SNOW

Simply put it will snow all weekend. Radar shows light snow over Eastern Ontario spreading into western Quebec at this hour of 8pm EST. This snow will taper Friday before another shot begins to wrap around a deepening storm near Cape Cod overnight into Saturday. That snow will become steady across the region especially south and east of Montreal. I think most regions of southern Quebec, New England and extreme eastern Ontario will see between 15 and 30cm by the time Monday rolls around. There may even be more at higher elevations. In addition to the snow winds will begin to increase out of the north on Saturday causing blowing snow. It appears that all forecasts are on track now keeping the mild maratime air well to our east meaning the precipitation will stay as snow. Travel safely...Happy New Year....

I may try to squeeze one more post in later on this evening before the bell tolls midnight. Thank you all again for reading. I have had over 37,000 hits this year. It means so much to me to share my passion for weather with all of you.
Be good, be safe... Stephen B.

Happy New Year

What has been a challenging year for so many, comes to an end tonight under partly cloudy skies and scattered flurries in Montreal. I wish everyone a healthy and happy start to 2010, a new year and a new decade. Be safe and please be good to each other...

Environment Canada has put out its annual list of the top 10 weather events for the past year. You can read them HERE.

STORM?
That storm system moving from the deep south towards Nova Scotia is becoming a real pain. Computer models have been all over the place with the forecast for this upcoming weekend. It will snow everywhere from the Ontario/Quebec border south and east. There is the potential for lots of snow in many areas, but where? Well that keeps changing with every model run. My best guess here, reading the area forecast discussions, is that we will have one of those long drawn out snow events lasting from New Years Day well into early next week. Montreal will remain on the western edge of a deepening storm that will move from Nova Scotia back inland across Maine and finally back out to sea. To complicate the forecast even more some models are predicting a warm front to usher in mild maritime air changing some of the precipitation to rain. As a matter of fact the high temperature forecast for Montreal by Environment Canada for Sunday is plus 5C, while the National Weather Service is forecasting highs below freezing for the same area. Whew! Ok so light snow all weekend. Roads will be slippery and snow covered and winds will be increasing from the north during the period. There is the chance for more than 10cm of snow and blowing snow by the end of the weekend. The storm will be far more intense from Quebec City eastward towards the Gaspe if your travels take you there. The forecast is very fluid so check back here often and prepare for winter weather if travelling.

Happy New Year!

New Year - New Storm

Some of the wind blown snow is plowed away (and blown away) in Beaconsfield yesterday.

Lots to talk about this morning in the weather department. First of all it is cold this morning, minus 18C here on Ile Perrot and -20C in the Ottawa area. Yesterday we had a blustery day with lots of blowing snow and biting wind chills around the mid minus twenties.

We can expect a sunny and chilly day today but the wind will ease. Tonight a clipper system approaching from the west will moderate out temperatures and produce a little light snow into New Years Eve. That will be followed by a impressive winter storm taking shape along the east coast of the US. Models have been all over the place with this storm. It is expected to rapidly strengthen east of Cape Cod before retrograding back towards the coast and into northern New England. Many questions are still up in the air regarding precipitation strength and location and wind. The potential does exist for a very heavy snowfall and wind event in the St. Lawrence Valley. The steady snow will begin New Years Day and continue well into the weekend. It is way to soon to pinpoint who will get what, but travel will be greatly impacted. More information will be posted later today on this storm which could be a big one for Montreal and southern Quebec.

• We have a second full moon this month tomorrow night to greet the New Year. The "Full Long Nights Moon" is classified as a "blue moon" because it is the second full moon this month.

• The NHL Winter Classic will be played outside at my favorite ballpark, Fenway Park home of the Red Sox. The game between the Flyers and the Bruins starts at 1pm New Years Day. The weather looks troublesome at this point from the same coastal storm we are concerned about.

Arctic front

An arctic cold front is currently pushing across eastern Ontario heading towards western Quebec. A brief period of heavy snow occurs along the frontal passage and drops several centimetres of snow in a very short period of time. Visibility in snow and blowing snow will drop to less than 1km rapidly. Keep this in mind if travelling the 416, 401, 417, 15, 20 or 40 in the next few hours. Radar is showing the front just west of Ottawa with heavy snow along the 417 to Renfrew. The temperature will fall rapidly with the frontal passage and winds will increase to 30-50km/h out of the northwest. North Bay has already fallen to -18C while Ottawa is -3C and Montreal -1C.

A special weather statement is available HERE. Skies should clear early Tuesday but it will remain windy and bitterly cold. The cold air will remain with us for the balance of the week with a good chance of snow on New Years Day and Saturday.

Winter Weather Advisories

The National Weather Service has posted Winter Weather Advisories for New York and Vermont from 7am Monday until midnight . A winter storm watch for lake effect snow is also posted for numerous counties bordering Lakes Huron, Ontario and Erie on both sides of the border. A potent low pressure trough will slide across the region Monday with a general 5 to 15cm of snow and gusty northwest winds over 50km/h expected in Montreal, Ottawa and points south into the northern US. Conditions will start to deteriorate in the afternoon as the snow becomes heavier and winds increase. In addition to the snow and blowing snow region wide, temperatures will begin to drop to lows by early Tuesday morning of -17C. Travel may become difficult from midday Monday through Tuesday morning along area highways. More snow in the order of 20 to 30cm is expected in the snow squall prone areas around the Great Lakes.

Unsettled week ahead

The most recent rain and freezing rain event appears to be ending across the region with just light drizzle and fog left behind. Most region had an impressive 20 to 30mm of rain and freezing rain with more locally. Hundreds of accidents were reported on icy roads and there were isolated power outages and a few minor transformer fires in the Ottawa Valley. The problem this morning is huge puddles everywhere as the snow blocks drainage paths and the new rain and ice pools on roads. This will become problematic late Monday as an arctic front roars through the region with dropping temperatures. Speaking of that front it will drop a quick 5-10cm of snow in many regions of Ontario, Quebec, New York and Vermont accompanied by dropping temperatures and strong winds. It could be interesting travelling Monday across the area so keep that in mind. Despite all the precipitation that has fallen, today may be the better day of the next three for travel in Ontario and Quebec. In addition to the frontal snow, the lake machine will rev up again with the potential for significant squalls south and east of Lakes Huron, Erie and Ontario. That would include portions of the St. Lawrence Valley for a spell late Monday and early Tuesday from Brockville to Kingston. I will update this event later today. For the short term the ice is over and conditions are improving. Montreal is currently cloudy and 2C.

Icy Roads

The freezing rain began in the Montreal area just after the noon hour today and has continued most of the day. It fell quite steady around 6pm with several millimetres accumulating on trees and wires. The roads were in decent shape but many of the sidewalks and parking lots were treacherous. As of 11pm the warnings have been dropped for the immediate metro region, but I am still showing 0C with a sleet and freezing rain mixture here on Ile Perrot. Across eastern Ontario and the Ottawa Valley the warnings remain in effect, however they have been lowered for Kemptville.

The front will slowly lift north of the region overnight and temperatures should warm to just above freezing allowing the precipitation to be rain. Any untreated roads will remain very slippery.

The photo above is from Merrickville, Ontario. Thanks so much Andy W. for reading and for allowing me to use the photo. The one below is of the sleet and ice accumulating on my car here on Ile Perrot.

Freezing Rain Warning

Steady freezing rain is expected to move into the St. Lawrence Valley overnight and move northeast towards Montreal by noon Boxing Day. Low pressure over Iowa has an occluded front draped to a developing second area of low pressure along the east coast. The combination of both these storms will produce moisture that is falling into the cold air at the surface. Freezing rain is expected to be most prolonged in the St. Lawrence and Ottawa Valley's where 5-15mm of ice accretion is possible. Winds will be gusting out of the northeast from 30-50km/h keeping temperatures at or below 0C. The freezing rain will last well into the evening on Saturday. Travel will become difficult on Saturday and power outages may be possible as well. Freezing Rain Warnings are in effect for southwestern Quebec and Eastern Ontario with a Winter Storm Warning in place for the US side of the St. Lawrence Valley.

Merry Christmas

Merry Christmas to all...

An active weather pattern is upon us with a major storm lifting north across the central US plains and into the Great Lakes. West of this system arctic air and strong north winds are producing a Christmas blizzard across the Dakotas, Minnesota, Nebraska, Wisconsin and north into northwest Ontario. Travel is nearly impossible with 30cm of snow and 80 to 100km/h winds. We will remain on the warmer side of the storm with freezing rain and rain. The precipitation has already started in southwest Ontario and is primarily rain. However temperatures at the surface remain below freezing in the St. Lawrence Valley as well as upstate New York and the Ottawa Valley. A winter storm watch is in effect for upstate New York while a freezing rain warning is posted for the Ottawa Valley and east central Ontario. I expect those will be shifted east into Quebec and Montreal. The precipitation will not start till overnight tonight and it will last well into Boxing Day. Look for 5 to 10mm of ice possible, enough to make travel very dangerous Saturday. Afterwards a strong cold front and cold arctic air will sweep the region Sunday with a burst of steady snow into Monday as the cold air deepens. Roads will be snow covered with low visibilities in blowing snow into Monday. Stay tuned for more information and an update on the warnings later today. Lake effect snow will also develop around the Great Lakes on Sunday.

Messy Boxing Day

I want to thank everyone for reading my blog on such a regular basis,

and wish you all a very safe and happy holiday season and a Merry Christmas.

TRACK SANTA NOW WITH NORAD

The weather picture is looking calm in Ontario and Quebec for today and most of Christmas Day. Afterwards a messy low pressure area from Texas will move north towards the central Great Lakes. Two things have happened with this system as the week has moved along. First, much warmer air will be coming north with the storm and secondly it has slowed down somewhat. Therefore the precipitation will start later and we are looking at primarily rain or ice as opposed to snow. Some of the colder more sheltered valley's such as the St. Lawrence and Ottawa may have a prolonged period of freezing rain on Saturday which will make travel very poor and possibly produce some power outages. The good news at this point is that precipitation looks lighter, in the order of perhaps 10 to 15mm. More details need to be ironed out on this forecast and I will update the blog late tonight or early Christmas Day.

Plan accordingly if you are travelling. On Sunday a strong arctic front will move across Ontario and Quebec with gusty winds, snow squalls and dropping temperatures. So travel Sunday into Monday will be no better. Conditions should improve late Monday as the low pressure lifts north and east of the region.

Track Santa

Here is a great site for tracking Santa with a peak at the weather as well...

Boxing Day Storm

It was a sharply cold morning today with temperatures at -16C at my home on Ile Perrot. I did not expect it to be that cold, add to that a west breeze approaching 20km/h and the air had an edge to it. Ok I am ready for summer now! I used my new snow blower and we are guaranteed a white Christmas so all is well, it can now warm up to 25 or 30C. On that note, in the irony department, places like Washington and Richmond, Virginia as well as large parts of North Carolina will have a white Christmas, while Buffalo, snow capital of North America has no snow cover at all and Burlington, Vermont only has a thin layer on the ground. Bizzaro Christmas!

A weak disturbance today will provide the area with a couple of centimetres of snow into Wednesday. While the accumulations will be minimal, the roads are icing up due to the cold. It should be very pleasant Thursday and Christmas Day with mild temperatures and sunny skies. The weather then becomes a challenge for traveling in Ontario and Quebec late Christmas Day and Boxing Day. As the storm develops over Texas and lifts into the Great Lakes, precipitation will overspread the region. It will begin as snow and then change to freezing rain and eventually rain in southwest Ontario and parts of upstate New York. It appears at this time, and we are several days out, that there will be an extended period of freezing rain possibly dare I say even an ice storm. But as I said, it is still days away and the track remains quite uncertain. There is also the likelihood of another low pressure area developing along the east coast of the US which would complicate the forecast, especially for us here in the St. Lawrence Valley. Stay tuned...but count on decent travel to your destinations, it just may be the return home that is complicated.

Christmas Day storm?

It was a blizzard for the record books across the middle Atlantic states and up into the extreme coastal areas of the northeast yesterday and today. Heavy snow whipped by 60mph winds fell in a narrow swath from western North Carolina and Virginia through DC and up into New York City, Long Island and Cape Cod. One to two feet of snow fell setting records. Nearly 2 feet fell in Philadelphia beating a record that dated back to 1932. The snow snarled traffic and closed airports in Washington, Baltimore and Philadelphia. Over 3000 accidents were reported in Virginia alone, with 3 fatalities. Washington recorded 18 to 22 inches of snow while parts of New York and eastern Massachusetts had 12 to 15 inches. In Suffolk County on the eastern end of Long Island, East Patchogue reported 27.5 inches of snow with 50 mph winds. The storm is now affecting eastern Nova Scotia with heavy snow.

Winter arrives tomorrow at 12:47 EST here in Montreal. It is just a formality as the cold and snow have been with us since the start of the month. This weekend was chilly but sunny across the region with just a few high clouds from the east coast storm. An Alberta clipper may give us a few flurries late Monday and into Tuesday. The real story will be a Texas low pressure area that is forecast to develop and move north towards the Great Lakes by Christmas Eve. This storm is expected to spread snow, freezing rain and rain across the Midwest and into Ontario and Quebec by Christmas Day. If you are travelling this week, please keep this in mind. The best chance of frozen precipitation will be Christmas Day in Ontario and Christmas night and Boxing Day in Quebec. Please check back often as the forecast is still 5 days out and lots can change.

Big storm...to our south

When arctic high pressure meets moisture you get snow, plain and simple. A strong area of high pressure currently over Quebec is producing the coldest air of the season with temperatures this morning in Montreal and eastern Ontario colder than -20C at numerous locations. It will "warm" to the minus teens today, but not much better. The weekend looks fair but cold with an increase in cloud cover and possibly a flurrie or two along the US border. The clouds and flurries will be in response to a big winter storm taking shape over northern Florida today. Last night an amazing 7 to 14 inches of rain fell in Broward County alone. The low pressure will deepen rapidly and move east of Washington D.C. late Saturday. Heavy rain along the coast will mix with and change to very heavy snow just inland. Over 2 feet may fall in the mountains of western North Carolin and Virginia with 6 to 12 inches closer to the coast. The snow will be driven by 30-50mph winds in some cases. A slew of warnings are flying this morning from the southeast all the way north to Long Island and southern New England. There is even a Blizzard watch for Long Island. In addition to the heavy precipitation, the wind will create high surf with the potential for coastal flooding and beach erosion. This will be a big and paralyzing storm for many east coast cities so if your travel plans take you there be advised there likely will be major delays and closures. I will update this storm later tonight.

Arctic Chill

Deep cold arctic air is moving into eastern Canada along a cold front today with plenty of instability and breezy conditions. As a result, an area of snow and flurries has developed and has become quite steady in Montreal and along the St. Lawrence Valley. The snow is being enhanced near any body of water as the cold air continues to flood into the region. The snow will continue intermittently for most of the day and a few centimeters may accumulate locally. Roads will become snow covered and slippery in the cold temperatures. We have likely reached our high for the day and temperatures will remain steady or drop slowly. Tonight skies will clear, and with the fresh snow cover temperatures will drop into the minus 20’s in eastern Ontario and southern Québec. It will remain cold right into this weekend.

More fog and ice

Ottawa Citizen photo of the carnage on Highway 416 this morning.

If you are travelling around eastern Ontario and southern Quebec tonight be prepared for icy roads and low visibility in fog. A moist air mass in place is creating ideal conditions for ice fog to form. Fog this morning led to two major multi vehicle collisions on Highway 416 between Ottawa and Manotick. Nearly 70 cars were involved in the crash with only minor injuries reported. The highway was closed for several hours. Similar conditions are possible tomorrow morning along with light snow and freezing drizzle. Radar tonight is showing precipitation in the region along the 20, 401 and 416/417. The air will dry out later in the day and it will turn sharply colder.

-46C!

At one point yesterday, Edmonton International, south of the city centre, was the coldest major city on the planet. The airport hit -46.1C at 5am yesterday morning, and warmed to a sultry -33C for a daytime high. The cold arctic air has the west in its grip with some relief in sight by the end of this week. In the meantime windchill warnings are in effect for all three Prairie provinces. It does not take much of a breeze to produce dangerous wind chills when the temperature is below -30C let alone -40C. The cold has established dozens of records in Alberta and Saskatchewan. The cold air has spread west over the Rockies and along the Pacific Coast. Couple that with moisture moving inland and you get heavy snow, lots of it in Vancouver and Victoria and inland. Some areas will have 20cm along the coast and up to 50cm inland by late Tuesday.

Montreal can expect an arctic front to cross the region Tuesday with a few centimeters of fresh snow and much colder air from Wednesday on. We can expect up to 5cm of snow with the front, along with gusty winds and the risk of some freezing drizzle. Temperatures will drop into the minus teens for the balance of the week.

Yesterday's little episode of snow dumped 7cm in Montreal and 10cm along the 401 at Cornwall. It was far more than the 2-4cm forecast, and it fell in under three hours. Numerous cars hit the ditch as roads became snow packed and visibility dropped to well under 1km. (See below).

Snowy Sunday

Travel southwest along the 401 and 20 was difficult this afternoon. PJ photo

That little bit of "light snow" this afternoon put down a quick 5-10cm of snow in the St. Lawrence Valley between 1 and 5pm this afternoon. I was attempting to drive from Ile Perrot to Kemptville, and gave up at Cornwall. The snow was heavy and wet with significant accumulations on the 401. The visibility in heavy snow was under 1km most of the afternoon with several cars in the ditch and travel slowed to under 70km/h. It has since tapered off to flurries. It is not to often I get caught in a missed forecast but today was one of those days. The warm air never made it down to the surface in the St. Lawrence Valley so instead of the precip changing to rain, it remained snow. The enhancement of the snow was from a frontal trough sliding southeast into New York state.

Light Precipitation

A low pressure passing well north of the region today will slide a frontal trough through the area. A shot of steady precipitation is accompanying the trough in the form of snow and rain with patchy freezing rain. The precipitation should taper off this evening with a total of about 2-4cm of snow and a few showers. There have been freezing rain warnings posted for southern Ontario as well as winter weather advisories for the Adirondacks and Green Mountains.

Once this system moves out another low will enter the region late Monday with yet another round of rain and snow. This will set us up for an Arctic front late Tuesday the will usher in the coldest air of the season and more lake snows for Ontario and New York. Speaking of lake snows, the radar shot above shows one of the plumes of snow off Lake Huron and Georgian Bay this past week. The wind was so strong aloft and the squalls so intense that they reached into southern Quebec, a distance of over 800km. I have never seen a squall off Lake Huron reach into this region before. The snow fell heavily all the way east to Lanark County where over 30cm fell in Franktown. Closer to the lake shore over 75cm of snow fell in the Grey and Bruce regions as well as the Muskokas. The same was true east of Lakes Ontario and Erie. Snow fell all the way east into Vermont. As much as 4 feet fell on the Tug Hill Plateau south of Watertown and in ski country south of Buffalo. More will fall later this week, but I don't expect them to be as intense.

The snow that fell on Ile Perrot last Thursday depositing a paltry 5cm originated all the way from Lake Huron. Hard to believe for certain.

Weekend Weather

The weekend weather looks windy and chilly for Saturday with another chance of some light snow or flurries for Sunday. Temperatures will be cold Saturday in the -5C range but warm Sunday to near zero.

Yesterday strong winds and the occasional snow squall made travel icy and slow in places across southern Quebec. Believe it or not a couple of centimetres fell on Ile Perrot from a plume of snow extending inland from Lake Huron over 800km to our west. That plume of snow was driven by 100km/h west winds of of all the Great Lakes. The snow piled up nearly 80cm in parts of central Ontario with as much as 20cm all the way east towards Smiths Falls and Lanark County. The Lake Ontario snow band dumped 2 feet of snow on parts of Oswego and Lewis and Jefferson County in western New York and extended as far inland as the Green Mountains of Vermont and the Seaway Valley.

The snow will continue today but shrink to the more traditional spots along the shore lines. Travel today on Interstate 81 and 90 is not advised in the warning areas adjacent to the lakes.

Flurries & Windy

The clean up is underway this morning slowing
morning traffic more than yesterday's storm did!

The big clean up has now begun across the Montreal area from the 28cm of snow that fell yesterday and overnight. It will take 96 hours and over 3000 pieces of equipment to remove the snow from city streets. It will also take 17 million out of the yearly snow budget to carry out the operations.

Another 3-5cm of snow can be expected today. Radar is showing narrow bands of steady snow off Lake Ontario in the traditional snow belts. These snow squalls are being driven unusually far inland by 100km/h winds and reaching far down the St. Lawrence Valley. They should begin to affect the Montreal region this morning. The heaviest snow, measured in feet, will occur in Jefferson and Oswego County in New York. The snow will fall for the next 24 to 36 hours. The same is true off the other Great Lakes. Buffalo even reported a thunderstorm with the snow during the last hour. Snow will also fall along the 401 from Brockville to Kingston.

Other totals from yesterday's storm include 20cm in Cornwall and 22cm in Ottawa. The other factor today will be the surface winds blowing out of the southwest at 40-70km/h in Montreal. They are bringing in much colder air. We have reached our high today of 1C and temperatures will begin to drop. As the snow becomes more granular, blowing snow may also become a problem especially south of the city.

Windy & White

The massive winter storm that has produced heavy snow, rain, wind, thunderstorms and flooding is now over Lake Huron and will slide east across Ontario and Quebec. The storm is dragging a sharp cold front across the region tonight with winds shifting from northeast to southwest and eventually northwest on Thursday. They have been gusting in Ontario to 111km/h at Long Point, 91km/h at Windsor and 74km/h in Toronto. Those same winds will invade the southern portions of Quebec overnight and I expect gusts to 70km/h. The wind will cause considerable blowing and drifting snow. Nearly 22cm of snow has fallen in Montreal (I measured 30cm on my deck here in Ile Perrot) with another 5-10cm quite possible through Thursday morning. Travel will be difficult in rural areas Thursday due to blowing and drifting snow.

In western New York an intense lake effect snow event is about to take place. Strong southwest winds will blow at 30 to 50mph off both Lakes Erie and Ontario and dump 1-3 feet of snow around Buffalo and Watertown, New York. Travel into or through those regions including Interstate 90 and 81 is not advised until at least Saturday.

In addition to the heavy snow, a lake shore flood warning is in effect as Lake Erie is expected to surge over 9 feet high with crashing waves into the shoreline around Buffalo and Niagara.

The pressure in this storm was so low today it resembled that of a Category 2 hurricane. The pressure continues to fall in Montreal and is currently at 987mb. The lowest I saw today in observations on this side of the border was 977mb at Wiarton, Ontario.

Storm Update

Staying ahead of the storm today in Kirkland, Quebec. SB Pic

Our major winter storm is located along the shores of Lake Michigan this afternoon. It has deepened to a 978 mb low with strong winds and intense precipitation. Steady snow continues to fall in Montreal with more than 15cm this morning. A storm total of over 30cm is expected. Winds have been increasing all day in the St. Lawrence Valley. Visibility has been under 1km for most of the morning at Trudeau Airport. The storm has a nasty cold front that is producing severe thunderstorms in western New York this afternoon. The precipitation will become light this evening in our area but continue through the night. Winds will increase as the cold front approaches and cause considerable blowing and drifting snow. The winds could gust to 70km/h late tonight and Thursday. Behind the front arctic air will pour into the region dropping temperatures and producing heavy wind driven lake effect snows in Ontario and New York.

Storm hits region

NOAA satellite photo of impressive winter storm early this morning.

10am Update: Heavy snow continues to spread north into the St. Lawrence Valley. Cornwall has visibility less than 1km with gusts of wind over 50km/h and Plattsburgh, N.Y. has near zero visibility in heavy snow. Travel is not advised today. Montreal is currently -5C, northeast wind gusting to 41km/h and 0.8km visibility.

The snow started shortly after 7am this morning on the west end of Montreal Island and is spreading rapidly north and east. The heavy snow is just southwest of our region. Already visibility has gone from 24km to 2km at Trudeau Airport and dropping. Winds are in the 30km/h range and will continue to increase as the morning moves along. The center of the intense low pressure area is approaching Lake Michigan at this hour with a wide swath of heavy precipitation along the (warm front) eastern flank of the storm. The heavy snow will continue all day today across eastern Ontario and western Quebec with he heaviest amounts in the St. Lawrence Valley from Montreal northeast where 25-35cm may fall. Ottawa and eastern Ontario is forecasting 15cm with 10-15cm across New England as a mix of sleet or rain mat occur. It remains very chilly in Montreal at -6C. Winter Storm and Wind Warnings are in effect for the entire region. Precipitation will become more scattered this evening before another burst of heavy snow along a powerful arctic front tonight. This will be followed by strong west winds Thursday from 50-70km/h causing cold wind chills and considerable blowing and drifting snow.

**Visibility is now down to 1km in Montreal as of 8am with winds increasing. School bus service has been canceled across Eastern Ontario and several school boards south of Montreal have canceled classes. Call ahead to the airport as flights are beginning to be delayed as well, especially to Toronto and the Midwest US. Drive slowly today or cancel travel all together.

Winter Storm Update

The big winter storm continues to rapidly deepen as it move northeast across the central plains and into the Midwest. Over 30 States have warnings posted along with three provinces at the moment. Winter Storm Warnings are in effect for all of southern and eastern Ontario and southern and Central Quebec. Heavy snow will move from southwest to northeast in the pre dawn hours Wednesday and reach Montreal by mid morning. The snow will fall heavily before mixing with sleet and maybe rain south of the city late in the day. I expect a good 15cm in all regions with 30cm locally. Winds will be fierce gusting 50-90km/h and up over 100km/h in Quebec City. The wind will greatly reduce visibility on area highways and may make travel along the 20 east towards the old capital impossible.

Stats are impressive so far with the storm with wind gusts over 90 mph in the southwest US. Over 250,000 people lost power in Phoenix last night as the cold front associated with the storm roared east. This will be a storm to remember. There is a real threat of power outages in many areas. South of the border in western New York, flooding is even possible along Lake Erie from a storm surge associated with the strong winds.

Here is a quote from the weather discussion out of Quad City, Iowa.

THIS STORM IS IMPRESSIVE. SNOW AMOUNT WISE...IT HAS BEEN ABOUT 10 YEARS SINCE SNOWS OF THIS MAGNITUDE AND EXPANSE HAVE BEEN SEEN. STORM STRENGTH IS ANOTHER MATTER. BASED ON THE CURRENT FORECAST OF A 980MB OR BETTER SURFACE LOW...IT HAS PROBABLY BEEN 20 TO 30 YEARS SINCE A WINTER STORM OF THIS MAGNITUDE HAS BEEN SEEN IN THE AREA.

I will update the situation early tomorrow morning.

Snowfall Warning

Environment Canada has posted a snowfall warning for southern and central Quebec for Wednesday. In Ontario for some reason no warnings have been issued yet despite a similar forecast for the St. Lawrence Seaway and Ottawa. I guess with the precipitation primarily falling as rain in the GTA, there appears to be no rush to advise the public of this dangerous winter storm. As the first storm of the year, it will be impressive tracking from Colorado towards Chicago and then north of Montreal. A heavy burst of snow will develop Wednesday morning in southwest Quebec and spread north and east. The snow will mix with sleet and rain in the afternoon in Montreal. Accumulations in our region will be in the order of 15-30cm with 15 at the US border and 30cm in the mountains of New England and north of Montreal. In addition to the snow gusty east winds will approach 60km/h before backing to the northwest Thursday and reach speeds up to 90km/h. The winds will blow around whatever falls.

We are not alone with this storm. Strong winds and heavy snow are falling from Arizona to Illinois with blizzard warnings in effect on the backside of the storm. In the warm sector severe thunderstorms are expected from Texas to Georgia.

Closer to home a Winter Storm warning is in effect for the Adirondacks and Green Mountains, with a Winter Weather Advisory in the Champlain and St. Lawrence Valley. A High Wind Watch has also been issued for New York and Vermont.
This is a difficult storm to forecast with bitter arctic air to the north and very warm air streaming in aloft. The forecast is very changeable so watch for updates today and prepare for nasty weather.

Storm update

Sorry folks, I am a little late on this update. Things are still on track for a big storm beginning late Tuesday in Ontario and Wednesday in Quebec. This is a difficult forecast because of the track of the system which appears to be from Colorado towards Chicago and then Ottawa. The facts are that it will be an intense low pressure area with lots of moisture (over 1 inch liquid) and very strong winds. It will be followed by the coldest air of the season on Friday. It is possible that Montreal and Ottawa could see 10-20cm of snow followed by mixed precipitation. It is also quite probable that we will have wind gusts approaching 100km/h. There are a slew of warnings out tonight across the US from the Rockies to the Great Lakes. I imagine we will see some watches posted locally by tomorrow morning.

The cold air that will invade our region set several record lows in Alberta this morning including -37.5C in Edmonton shattering the previous record of minus 35C in 1972.

BIG storm this week

The mainstream media is finally picking up on what we have been talking about on this blog for a week, the first big winter storm for southern Quebec. While many parts of the country are already having mid winter weather, such as the Prairies and the region around the snowbelts of Lake Huron, we have been relatively mild and snow free. A burst of flurrie activity overnight put down 1-2cm of snow across our area. Another weak area of low pressure will move across the valley this afternoon with another 1-3cm of very light fluffy snow. This is just a warm up for what lies ahead. Tuesday will be the calm before the storm as high pressure dominates with clear and cool weather.

975mb Low
Low pressure will emerge from the southern Rockies and move to near Chicago on Wednesday and just north of Montreal on Thursday. This low is expected to intensify rapidly to a 975mb low. The intense storm will produce heavy precipitation north and east of the system. It appears that snow will start across Ontario late Tuesday and spread into Montreal by Wednesday morning. The onset will be all heavy snow with 10-20cm expected before a push of warmer air and a transition to freezing rain and sleet from Montreal south. From Montreal north it should remain all snow with 25cm plus expected. There may even be some rain along the US border. There is still some question as to the track of the system, but the described scenario above is becoming more clear with each computer model run.

Another component of this storm will be fierce winds. Winds will be northeast from 30-60km/h and then backing Thursday to the northwest 50-70km/h and gusty. These winds will cause blowing snow and reduced visibility. Air and road travel will be impacted all over the Northeast, New England, Ontario, Quebec, the Midwest and eventually the Maratimes. Plan your week accordingly.
The next update will be no later than 7pm this evening.

First Snow Alert

Snow in Clagary (left) and Houston. Our turn will be this week.

CBC.ca and the Houston Chronicle.

I have been interested in weather since I was a child growing up in Verdun. I began keeping daily weather records in 1979, yep 30 years ago! I used to go by the name VAWB (Verdun Amateur Weather Bureau). It was a little harder in those days, not the same technology we have now, you really had to watch and understand the weather to make a prediction. One thing I liked to do back then was issue my own warnings for people when I felt the forecasters were being a little cautious. One such warning was only issued once a year, the first snow alert. So today I am warning all my readers and friends, we have a first snow alert posted for Montreal, southwest Quebec and all of eastern and Southern Ontario.

Here is the long played out scenario: First of all the Houston snowstorm will move off the middle Atlantic coast today and hit the Maratimes tonight. The Calgary storm that produced visibilities of less than 1km for over 10 hours will slide just south of Montreal on Monday and produce a general 1-3cm snowfall in our region. Cold air will then pour into the region behind that storm while low pressure begins to organize in the US southwest.

The southwestern storm will then move across the Midwest and to near the lower Great Lakes on Wednesday. This storm will have good atmospheric support, a strong wind field and plenty of moisture as it passes just south of Montreal mid week. Combine that with the newly arrived cold air mass, and we are looking at our first snowstorm potential for Wednesday and Thursday. It is early yet, but successive computer model runs are pointing to s significant winter storm for Ontario and Quebec. Stay tuned folks!

Snow in Houston

Interstate 10 in Houston, Texas today.

Quite the weather event taking place today across the deep south. Snow has been falling in the Houston metro area most of the day with a couple of inches of slushy accumulation reported. Winter weather advisories are in effect and freezing temperatures are expected right down to the Gulf of Mexico. When I checked about an hour ago Galveston was actually colder than Montreal with a reading of 2C and light snow.

The winter weather is being caused by an upper level low that is expected to lift northeast from the gulf states towards Cape Hatteras. Snow will spread across the deep south tonight and northward into the middle Atlantic and southern New England. This will be a coastal event with very little effect here in Montreal. Some light snow may spread into southern Vermont. Nova Scotia has posted winter storm watches for their province. Depending on the exact track of the low pressure, 15-25cm of snow could fall.

Southern Saskatchewan and Alberta are bracing for blizzard conditions tonight as cold air pours into that region. 10-15cm of snow with winds up to 70km/h is expected to produce dangerous travel and zero visibility. As the cold air moves south and east we can expect temperatures to gradually lower in Quebec and Ontario as well over the weekend. It will be a slow process. Snow may affect our region by next Wednesday as another storm lifts out of the US towards the Great Lakes. Speaking of the lakes, snow is falling around them in western New York and central Ontario today. Some portions of upper Michigan saw over a foot of snow yesterday.

Of Note: Houston has had more snowfall than Burlington, Vermont this year to date!

Warm vs Cold

It was a very different weather day today depending on which side of the country you reside. Along the east coast heavy rain and mild temperatures made it feel more like September than December. Dozens of record highs were established for the date in New England including 20C (68F) in Boston and 14C or 57F in Burlington, Vermont. Burlington has yet to have any snow this season which means it is just short of the record for the latest start to winter. That occurred in 1937 when it did not snow till December 7. Winds in the northeast gusted out of the south over 50mph in many areas including Boston. South of Boston at the Blue Hill Observatory a gust to 70 mph was observed.

Montreal was 8C today with about 25mm of rain here on Ile Perrot just southwest of the city. The mild air is being chased out by gusty Northwest winds tonight. It will be cooler this weekend but the main batch of Arctic air will hold off till next week. There is a chance we could see measurable snow on Monday with a greater chance of a storm by Wednesday or Thursday of next week.

Prairie Blizzard...
In the west it is a very different story. Temperatures struggled today to reach -10C across Alberta and Saskatchewan and they have fallen back tonight to -17C in Regina and -20C in Assiniboia. This is just a taste of what is on the way. Winter Storm Warnings have been posted for most of central and southern Alberta for Friday, and they will likely be extended east into Saskatchewan. A strong arctic cold front will slide southeast across the region Friday with intense winds in excess of 50km/h, snowfall of over 15cm and dropping temperatures. Blizzard conditions are likely outside of the major urban areas and travel will be difficult. The front will clear the region and in its wake leave an arctic air mass with temperatures in the minus 20's. It will remain cold all next week.

Heavy Rain Warning

Low pressure with a wide swath of heavy rain is moving north towards Ontario and Quebec tonight. Radar at 10pm is showing bands of very heavy rain with some freezing rain in isolated pockets moving into the region. The heavy rain will begin overnight and taper off late Thursday. Total amounts of 30-40mm are forecast. In addition to the rain strong winds will develop in the St. Lawrence Valley and gust to over 60km/h. Environment Canada has posted a heavy rain warning for Montreal and the surrounding regions. Currently it is 4C on Ile Perrot so I expect straight rain in the region.

Heavy Rain

Snow and cold temper spirits in downtown Regina yesterday.

Low pressure deepening over the Gulf states is expected to lift north across upstate New York over the next 24 hours. The inland track of this storm will guarantee Quebec and eastern Ontario mild air and rain. Today should be sunny and mild with high temperatures around 5C. Clouds will rapidly thicken tonight, and the rain should begin by midnight. Mild air tomorrow will push temperatures to near 10C with a steady rain all day. Indications are that 25-35mm will fall. It will be windy with gusts over 60km/h expected. This would have been a great first snowstorm!

Winter is settling into portions of the country. It has turned sharply colder across the west with snow falling from Calgary eastward towards Winnipeg. Some parts of southeastern Saskatchewan had 15-20cm yesterday, and it was blown around by cold northwest winds over 50km/h. It is bitterly cold this morning with reading in the -10C to -20C range in Alberta and Saskatchewan, including -20C at Stony Rapids. That arctic air mass will move east but modify as it moves into Ontario and Quebec. Temperatures will cool significantly this weekend with flurries possible, especially around the great Lakes. Low temperatures will be in the -7C range with highs staying below freezing at -1C.

First SNOW

Photos of the first accumulating snow of the season
this morning on the West Island of Montreal.

As expected weak low pressure moved across the area overnight and the light rain changed to light snow at around 1am in Montreal. As of 8am about 2cm had accumulated locally with another 1cm or so expected. Roads are slick in spots especially in your own neighborhood, with numerous accidents reported. SLOW DOWN. The snow should end by noon with clearing skies and dropping temperatures to a low of -5C tonight. The balance of the week will be unsettled with another major storm on Thursday. That system will bring rain to the valley but heavy wet snow is possible northwest of Montreal. We will have to nail down the track of the system as each successive computer run is bringing more of a western tack through the region which would mean rain not snow for Montreal. More later today on that system.

137 mph winds!

Well it appears winter is upon us. OK my headline caught your attention. First off the move is complete and I am now back among the cyber living with a new Videotron Cable internet connection and in a new home southwest of Montreal about 50km from the downtown.

Now the winter thingy...that storm on Friday that bombed out moving up the east coast, produced some impressive snowfalls east and south of Montreal. Here in the city not even a flake. We had 15mm or so of rain and gusty winds close to 50km/h at times or about 30mph. Well compare that to Mt. Mansfield where 20 inches of snow fell and winds topped out in the 50mph range. Not enough yet, how about Mt. Washington. They recorded there strongest wind of 2009 with and incredible & unbelievable gust to just over 137mph. (use the link on left to read the observers comments). Combine that with sub zero cold wind chills and nearly 25 inches of snow and you can see it was a storm to be reckoned with.

We are going to see a transition in the weather pattern this week with winter beginning to settle in. It has been a warm November, but as the month draws to a close several fronts and low pressure this week should bring us our first accumulating snow. Tonight showers will develop and change to snow by morning from Ottawa across the Laurentians and into Montreal. A few centimetres may fall north of the city. An even better change of snow will come Thursday as low pressure moves up the Atlantic Coast. Cold air will be established over the St. Lawrence Valley, and snow is expected. How much? Too soon to tell, but be ready for winter weather this week. I will update this situation later today.

By the way today is the Grey Cup in Calgary. The forecast is expected to be ideal for football, partly cloudy and 8C.
GO ALS GO!

GREY CUP CENTRAL

Weekend snow

First off Happy Thanksgiving to all our American friends. Secondly, the move is nearly complete, however thanks to Bell once again, our phone service is delayed. This means no computer connection at the moment from home.

Traditionally this is the time of the year where we begin to see our first accumulating snows in our region. This will be the case this weekend for many portions of Ontario, Quebec, New York and New England. Low pressure developing off the US east coast will move north towards the Maratimes. Steady rain will develop today in most areas with a gusty and chilly northeast wind. Tonight as the temperature lowers the rain will change to wet snow northeast of Quebec City and across the higher elevations of the Townships, Greens and Adirondacks. Look for between 15-25cm of wet snow to accumulate at the highest elevations. Additionally there will be gusty northwest winds developing on the back side of the system. These winds will exceed 50km/h and produce blowing snow. Environment Canada has posted a Heavy Snow Warning for the Townships while a Winter Weather Advisory is in effect for the Dacks and Greens.

In the lee of Lakes Huron, Erie and Ontario, a round of lake effect snow is possible late Friday into Saturday. In Montreal a cold rain today will taper off to a few flurries Saturday with a gusty Northwest wind of up to 60km/h.

If you are travelling south today for the US holiday or Black Friday, keep in mind that travel will become poor on many roadways across Vermont, New York and southern Quebec. The low pressure is expected to bomb out (rapidly intensify) near Portland, Maine tonight and move into Atlantic Canada with very strong winds and heavy precipitation.

Week of transition

It was a busy weekend as valleyweather moves from the south shore of Montreal to the just off the western tip of the Island of Montreal about 50km to the west. It will take a few days to get things properly up and running so the blog entries may be a little small.

This truly is a week of transition both personally and in the weather. The week will start off sunny and mild, although this "dirty" high pressure system continues to allow for low clouds and fog to form in the past 24 hours, this should burn off shortly. Temperatures continue well above normal for November, close to 8C. By Wednesday the first in a series of low pressure areas will begin to affect the region. Showers are expected from Wednesday into the US Thanksgiving holiday. By Thursday low pressure organizing along the Carolina coast will move north towards Long Island. Precipitation in the form of rain will spread inland from south to north across Vermont and New York and into Quebec and Ontario. At first rain is expected, but as cold air moves into the region from the north, we expect the rain to mix with and change to snow Friday night. It is very early in the forecast period, but be advised that colder weather and some snow is in the extended forecast. More on this later in the week.

Weekend Forecast

An active but fairly weak weather pattern is upon us this Friday morning. A frontal system has produced some rain and drizzle this morning in Montreal. This will slowly taper to showers for the balance of the day. Strong southwest winds will develop along and ahead of the associated cold front and will produce gusts up to 70km/h in the St. Lawrence Valley by noon. Skies will remain cloudy tonight and most of Saturday before high pressure gives us a clear and cool night Saturday. Sunday at this time looks sunny before another system moves of the Atlantic Coast. Temperatures this weekend will be near normal with highs near 5 or 6C and lows just below freezing. Any fog that forms Saturday night could freeze on surfaces, keep this in mind when driving. This week, ice fog in Montreal resulted in several serious accidents. SLOW DOWN!
The system that is currently taking shape along the Gulf Coast will be another decent storm for the eastern seaboard. At this time the system is forecast to move along the gulf this weekend and up the east coast of the U.S. on Monday. Montreal will remain on the extreme western flank of the precipitation. From 1-3 inches of rain is expected along the track with gusty winds and high surf, but nowhere near as bad as Ida was last week. However keep in mind that tremendous damage was done to the dunes and beaches, and any high surf is causing problems in the Carolina's north to New Jersey, especially the Outer Banks.

More information on this storm over the weekend. Be safe.

Slippery commute

The fog rolls in just after sunrise this morning along the Lakeshore in Montreal. The conditions made roads very slippery.

A little taste of winter this morning along the St. Lawrence Valley here in Montreal. After a brilliant sunrise just before 7am, the temperature lowered to dew point temperature and dense fog began to rapidly form along the riverfront. The fog spread across the region and deposited a thin layer of moisture that froze on contact with bridges and overpasses. The result was several serious accidents and a very slow commute in the Montreal region. At 6am this morning Trudeau Airport reported 24km visibility with clear skies. As of 9am we were down to 0.8km visibility with ice fog being recorded by the observer. Roads, especially elevated surfaces, remain slippery. Caution is advised this morning while traveling until about noon when the sun will burn off the fog.

Rare November weather

Out of the fog: The tropical air mass from the east coast storm produced high dew points and plenty of fog in Montreal this past weekend. The photo is of the St. Lawrence Seaway early Sunday.

Strong high pressure is dominating the weather in southern Quebec and eastern Ontario this week with abundant sunshine in what should be the cloudiest month of the year. Temperatures will be near normal, 6C during the day and just below freezing at night. The next chance of rain will come by Friday.

Yesterday we had some wild weather across the middle portion of the continent. While it was snowing heavily in Kansas, Nebraska and Colorado, northern Alberta had record highs. Portions of northeast Kansas had nearly a foot of snow with 8 inches in Denver. Meanwhile Edmonton shattered their record high, reaching 14C breaking the previous high of 10.9C set in 2001. There were several other record highs in northern Alberta as well.

Rainy Saturday

Clouds are rapidly thickening up as the moisture shield from the remains of Ida nudges across northern New England and into southern Quebec this morning. The main wind has remained along the immediate coast from Maryland north to Maine with just a northeast wind up to 20km/h in Montreal. Gusts to 45mph are possible along the immediate coast. Inland the rain may accumulate from 15-25mm (1 inch) locally and taper to showers tonight. The center of the storm has moved east off the coast of North Carolina, and is well removed from the moisture. The surf is slowly subsiding along the coast, but not after producing record damage in some locations.

Bill left me a comment below directing me to an incredible site with awesome pictures of the recent storm damage on Hatteras Island in the Village of Rodanthe. The subject of many of the photos is a home named Serendipity which was the main star in the film Nights in Rodanthe. I have taken numerous pictures of the house myself and walked that very beach several years in a row. None of my photos come close to these amazing pictures that Bryan Elkus has taken.

Coastal storm stays south

Above: The cloud deck from the coastal storm and smog along with a thick frost along the South Shore of Montreal this morning. Below: The remains of Ida form a big coastal storm off the mid-Atlantic coast.

The big east coast storm that continues to batter the region from the Carolina's north to New Jersey will begin edging towards our region today. Already sat photos are showing the cloud deck moving into southern Quebec. Clouds will continue to lower over the next 24 hours before rain moves in Saturday. Montreal will remain on the western edge of the storm and therefore we are only expecting light rain.This is not the story along coastal areas where heavy rain and strong winds have produced serious flooding and damage. Thousands are without power in Virginia and North Carolina. The Outer Banks have been hammered by successive high tides producing major flooding. NC 12 is closed on Hatteras Island from Oregon Inlet to Rodanthe. It may reopen later today as the storm slowly moves north. Storm warnings and coastal flood warnings are now posted as far north as Cape Cod. Heavy rain will overspread New England tonight. In Norfolk major flooding has occurred along the coast, and power is out as winds gusted to near hurricane strength yesterday.

Coastal Storm Update

North Carolina 12, in the center of the picture, is washed over with sand and surf while the mighty Atlantic is on the right. This image is looking north from the Village of Rodanthe on the Outer Banks at 8:12 this morning.

The remains of Ida combined with high pressure over Quebec continues to produce a significant wind and water event for the mid Atlantic coast from Long Island south to the Outer Banks of North Carolina. Web cams this morning are showing a fierce Atlantic Ocean rising up and in some cases over the dunes producing severe flooding, especially along the Outer Banks and in Virginia Beach. The still shot above is from the web cam looking north from the Village of Rodanthe, a place I know very well. Hatteras Island is narrow at this location and subject to ocean overwash. Winds in the region are gusting from the northeast to 60mph and many regions have reported 3 to 6 inches of rain. Numerous warnings for flash flooding, high surf, high winds and coastal surge remain in effect from New York City to South Carolina and inland up the Chesapeake Bay towards Washington.

The northern extent of the precipitation is into New Jersey while the extreme edge of the cloud shield made for a brilliant sunrise in Montreal today. It appears this system will stay south of Quebec and northern New England for now.

Remains of Ida pounding Mid-Atlantic

The combination of the remains of Hurricane Ida, a frontal system and low pressure north of the Bahamas are expected to produce a long period of heavy rain, wind and high surf from North Carolina to New Jersey. Flash Flood Warnings are in effect for the Carolina's, Virginia, Delaware and Maryland. Coastal flooding is expected along the Outer Banks tonight through Friday afternoon. Ocean over wash is possible along NC12, and it could become impassable. Flooding is expected to be as bad as with Hurricane Isabel in 2003 in many areas of Tidewater of Virginia and Chesapeake. Storm force winds are already blowing along the coast with gusts over 40mph at the Bay Bridge. More information on this story can be found here at The Virginia Pilot Online.

Remembrance Day

Please take time to remember today.

The weather will be ideal for most parts of the country this November 11. Temperatures are close to normal here in Montreal and Eastern Ontario (plus 7 to 10C). It will be sunny and dry. The evenings will be seasonable with lows below freezing (0C to -4C). The next chance for rain will come this weekend. There is not much certainty at this time with the weekend forecast as we wait to see what the remains of Hurricane Ida do.

Ida moved inland along the Alabama coast yesterday with high surf and very heavy rains. The rainfall amounts will be excessive in the 4 to 8 inch range (so far almost 6 inches of rain have been reported in Alabama and the Florida panhandle). As the system moves off the southeast coast it is expected to become a very intense coastal storm with strong winds and destructive tides along the coast from Georgia northward to the middle Atlantic and especially the Carolina's. Numerous warnings are in place for coastal flooding and storm surge. NWS radar this morning is showing very heavy rain in the Carolina's and showers from the system as far north as New York City. High pressure over our area combined with Ida will produce a strong onshore flow along the Atlantic Coast along with strong storm force winds. Coastal damage is expected.

Indian Summer

Indian Summer, is when the weather is sunny and warm, and above normal, usually 21°c (70°F), and all of the leaves of the trees have turned but before the first snow has fallen. A true Indian summer occurs after the first frost, generally a killing frost, of the season.

It really looked like this would be the year not only without a summer, but also without an Indian Summer, but I believe we qualify for this today. The temperature has reached 18C so far at the airport in Montreal (close enough), warmer downtown, and 21C at St. Anicet and along the US border in Champlain, NY. What a glorious day with plenty of sunshine. Enjoy!

Hurricane Ida

It is fitting that post number 800 for Valley Weather will be about a Hurricane...

Hurricane Warnings are in effect for the US Gulf Coast from Mississippi over to the Florida panhandle, while a Tropical Storm Warning is posted for the Louisiana coast including New Orleans. This morning Hurricane Ida is located about 235 miles SSE of the mouth of the Mississippi River and moving NNW at 16mph. The storm has lost some strength and is now back to a Category 1 after peaking at a 2 with 105mph winds yesterday afternoon. Very little change in strength is expected before the storm moves inland tonight. There is still some uncertainty in the forecast track, but despite that, the storm will still bring rising surf and heavy rains to the region. A surge of 3-6 feet above normal tides is expected along with 4 to 8 inches of rainfall. It is still too soon to tell what further impacts up and along the east coast that Ida will have, but most indications at this time are that the system will remain to the south and east of New England. Heavy rain is forecast in the southeast US.

Weekend Weather

Tropical Depression Ida this morning

Post Number 799

We finally have some active weather to talk about, just not here. It has been a very quiet weather week in Ontario and Quebec with just a few flurries and sprinkles this morning along the US border. They should end by noon with clearing skies for the weekend. It will start off chilly today and Saturday morning. Today we will only warm to 5C with a north breeze. Winds however will veer to the south tomorrow and milder air will flow into the region. Look for temperatures of 10 to 12C for the weekend.

The active weather lies on both coasts like bookends. A strong Pacific storm is bring heavy rain and snow to BC and the Pacific northwest. Rainfall amounts of 50-100mm occurred along with heavy mountain snows. Winds were very strong as well with this storm. On the east coast a strong nor'easter is pounding the Nova Scotia and Newfoundland coasts with winds over 110km/h, high surf and up to 25cm of snow in the interior of both provinces. The cutoff for the precipitation is sharp with warnings confined to northern and eastern Nova Scotia and most of Newfoundland.

The last big story is we have a tropical system in the Caribbean Sea along the Honduras and Nicaraguan border. Tropical Depression Ida developed yesterday and reached storm strength with winds of 60mph. She has since weakened slightly to a depression as the system interacts with the land. The storm is expected to move into the southern Gulf of Mexico on Saturday and strengthen into a tropical storm once again. Heavy rain is producing flash floods along the Central American coast and especially over higher terrain inland. All interests along the US Gulf Coast from Texas to Florida should begin to monitor this system. It has been a very quiet season and with the end in sight, many have let their guard down. November hurricanes, while rare, can still pack a punch. Hurricane Jeanne back in 1980 flooded parts of the Florida Keys before moving up the east coast as a major storm with rain and even snow inland. Ida is following, to this point anyway, a life cycle similar to Jeanne. Stay tuned!

Breezy and cooler

Parts of Nebraska had record snow for the month of October with several areas recording there annual average in one month! Photo of North Platte, Nebraska from AccuWeather

Showers are slowly moving across the region this morning in advance of a cold front. They are light in nature and should taper off by noon. It will turn windy this afternoon behind the cold front with temperatures dropping to -3C tonight. Combine this with Northwest 30-50km/h winds and it will be an early taste of winter. Another frontal system and associated low will affect the region on Thursday with rain and mountain snow showers. A dusting of snow is possible in the Laurentians, Greens and Adirondacks. It will remain very chilly right through Friday. The weekend at this time looks quite pleasant with sunshine returning and much milder temperatures near 10C once again.

Pleasent weather to start week

A windy, wet Halloween on the West Island of Montreal

It was a very windy Halloween across the island of Montreal, with peak gusts over 70km/h. The good news was that the rain was much lighter than expected with about 9 mm falling. The wet weather was over by trick or treat time, but the wind continued well into the overnight before diminishing. Sunday was sunny with cloudy periods and breezy, but mild for early November with temperatures around 10C.

Monday will be fair before unsettled weather for the balance of the week. Several cold fronts will affect the region with showers at first but the threat for flurries by Thursday as much colder air moves into the St. Lawrence Valley and New England. Daytime highs in the 7 to 10C range will lower to the 3 to 5C range by Friday.

Windy & Spooky

A windy, very spooky and mild Halloween is in store across Ontario, Quebec and New England. Very strong low pressure is moving north across central Ontario and into Quebec. It will draw a potent cold front across the region today. Along the front heavy rain is falling, but the big story is the wind. Wind Advisories are in effect for the Richelieu Valley and south shore in Quebec as well as Prince Edward County in Ontario and northern New York and Vermont. South winds are gusting to 60km/h and will increase to gusts to 90km/h as the front approaches. It will be mild with temperatures in the upper teens (60' F). Once the front passes temperatures will drop down to more seasonable values with clearing skies and diminishing winds. The shower activity will become more spotty for the trick or treaters in Montreal and Kemptville tonight. Please drive safely.

Remember to put your clocks back one hour tonight to standard time.

A windy Halloween

Snow fell in Denver this week. Are we next?

The strong winter storm that has been affecting the US Rockies and central plains is beginning to move northeast. The storm was responsible for nearly 40 inches of snow north and west of Denver with roads closed and power outages reported. The system is trailing a cold front that has produced severe weather in the Midwest and southern plains. That cold front will play a major role in our Halloween weather. As the storm moves across the Dakotas and into northwest Ontario, the cold front will approach the St. Lawrence Valley. Look for strong southwest winds ahead of the front to develop tonight and push the mercury up to the 19C mark in Montreal for Halloween. That is the good news. The bad news is it will be blustery with winds gusting from 50 to 70km/h and even approaching 90km/h in places. We may need advisories on this weather situation, but that will be determined at some point later today. It will not be a washout, but the front will generate a period of heavy showers late in the day Saturday. It will be cooler and dry on Sunday as high pressure follows and the temperature reaches 10C.

Next weeks weather looks interesting by the end of the week, and by that I mean snow is possible. I put my winter tires on the old Saturn this morning, and usually I am pretty good with these things. I would do the same soon as well.

44,000 Hits

Wow, ValleyWeather surpassed 44,000 hits yesterday morning. Thank you from the bottom of my heart for reading. Many of you have asked me weather questions, and friends and co-workers often ask me the weekend forecast and I thank you as well. I always have time to talk weather and have for the last 30 years, since September 1979 when I tracked my first hurricane - David - along the east coast of Florida and started recording daily weather.

My interest in weather actually started much earlier during the winter of 1971 when a fierce March snowstorm closed down Montreal for several days. It caught my young attention span and managed to keep me still for a day just watching the weather outside. Hurricane force winds and 45cm of snow in one day will do that. There have been so many memorable weather events in those 30 years. Some that stand out are the day the Decarie and most of Montreal flooded on July 14, 1987, and shortly after that the terrible Edmonton tornado on the 31st of July 1987. Hurricanes Hugo, Andrew and Katrina, just to name a few. Others are the 1998 Ice Storm, my first tornado in Saskatchewan in 1998, Tropical Storm Allison in June 1995 on the Outer Banks of North Carolina, the Halloween Nor’Easter in 1991 (the Perfect Strom) and the March 1993 east coast super storm. That storm on March 13, 1993 (43cm) was the only day that I could not get the Montreal Gazette newspaper out to the paper carriers and stores in my entire career at the paper. There are so many more events, too many to mention them all.

Anyway it has been a very challenging year personally for me and I have not always updated ValleyWeather as often as I would have liked to. So for sticking with me I thank you again. I will be relocating in a few weeks and setting up my home weather station again, so I hope to have better and more local weather information and maybe even a web cam in the near future.

Be good and be safe…

**Today will be cloudy across the region and chilly with northeast winds in Montreal, and no better than 9C for a high temperature. Showers are possible especially south of the city towards the U.S. border. Skies will clear out for Thursday and it will be sunny and mild into Friday. It looks like Halloween will be wet, but there is still time for the forecast to change and a window of opportunity for tricks and treats to open up. Next week looks cooler, with a chance of some snow again by mid week.

Sunny Monday

Cross border shoppers were not the only Canadians taking a break on Sunday. These geese paused on their flight south along the Lake Champlain shoreline just off Route 9 in Plattsburg, NY.

It was a mixed weather weekend in our region with steady rain and windy conditions Saturday followed by cooler but dry weather Sunday. About 20mm of rain fell in Montreal Saturday with much less to the north and west, (6mm in Kemptville) and more south and east of the city. Portions of Vermont had nearly double that amount.

High pressure will remain in control today, with a sunny and cool day, close to 7C. A weak area of low pressure will move across the area tonight with just a couple of showers or flurries. A stronger system will impact the area on Wednesday with a greater threat of rain. The week will be mild, with no major cold outbreaks in sight. It is early in the forecast period, but it looks like Halloween could be on the wet side. The rain may taper in time for the trick or treaters. More on that later in the week.
