Snowy morning in Montreal

The Davis Vantage Vue in my backyard continues to preform despite the heavy wet snow on top of.

Low pressure continues to meander near Lake Ontario in upstate New York this morning with the main area of snow starting to weaken and move northwest of the greater Montreal region. The light snow falling this morning across the St. Lawrence Valley should end by noon with just a few flurries or showers into the afternoon. I measured around 15cm of heavy, hard packed wet snow on my driveway. This stuff is heart attack snow, I moved just a few shovels of it and opted for the snow blower later this evening.

The snow is wet in nature and has stuck to everything making for a beautiful landscape this morning. (ValleyWX)

Trudeau Airport measured about 16cm yesterday in addition to what fell overnight. I am thinking most of the Ottawa Valley into Montreal will end up with close to 20cm (8 inches) for this event. The low pressure will be very stubborn to move out with weather systems being blocked by Atlantic high pressure. So expect clouds and light precipitation well into the weekend. We could pick up another 2-4cm of snow over that time frame. Temperatures will remain mild, with little in the way of diurnal range, highs generally 0 to 2C lows -1 to -3C.

Heavy wet snow in Montreal

The snowfall warning remains in effect as wet snow continues to fall across southern Quebec and into eastern Ontario. Gusty winds up to 50km/h are making for a raw night outdoors. As of 9pm about 10cm (4 inches) has fallen here on L'Ile Perrot since about 3pm. Prior to that is was just too mild and the snow was melting on contact. Snow will continue overnight, mostly light, but with pockets of heavier snow, especially across eastern Ontario. Temperatures will remain steady near 0C.

SNOWFALL WARNING: Metro Montreal
Radar this morning is showing decent precipitation moving north into southern Quebec from twin low pressure areas. We have most locations reporting a mix of rain to snow with pockets of heavy wet snow. The strongest returns and heaviest precipitation at this time is falling over St. Lawrence County, NY moving north into eastern Ontario. This will be affecting the 416 corridor over the next several hours with heavy wet snow north into Ottawa. Montreal can expect light precipitation to begin shortly with rain at the onset switching over to snow. Temperatures will be near the 0C mark for the next 24 hours making this a difficult forecast. A spattering of warnings are in effect including a snowfall warning for metro Montreal. Amounts will be widely variable and range from 5cm up to 20cm (2-8 inches) depending on location and elevation. Winds will be a factor gusting up to 60km/h out of the northeast.

Overnight snow and rain has caused travel issues across southern Ontario and in the GTA. There are numerous accidents as well gusty winds have brought down some trees and power lines. The travel delays are not reserved to the road with VIA Rail reporting 20 minute delays or more in the Montreal to Toronto corridor as well as 20 percent of the flights cancelled or delayed at Pearson Airport.

Radar at 7:15 am showing two main zones of precipitation from the two storms, with a dry slot between. A very difficult call for snow totals.

Low pressure areas will slowly move north today, one over Ohio, the second off the mid-Atlantic coast. Look for precipitation all day into the overnight for southern Quebec. Most time it will be light but there will be heavier bands within the system.

Difficult stormy forecast

One thing is certain about the upcoming storm, there will be one. The question will be, who gets rain and who gets snow? Today, the calm before the storm, we have ice fog this morning with visibility down to 0.4km at Trudeau. That should lift shortly with a mild, partly sunny day and high temperatures near 2C. It will be mild tonight with lows down to -3C. Mild again on Wednesday as the storm starts with highs near 1C.

As far as the storm goes, a betting man would say snow north of Montreal, mix in the city and rain south and east of the metro region. It looks like Ottawa will have all snow with over 15cm possible, same goes for the Laurentians. Burlington, Vermont west towards Cornwall and points south, mostly rain with perhaps a few inches of slushy snow. The big question mark will be here in Montreal and in general the St. Lawrence Valley. Northeast winds can often keep temperatures just cold enough at the surface for snow or freezing rain, especially in this type of a scenario. The wind will be out of the east at 40-60km/h. The official word from Environment Canada is 5cm of snow mixed with rain on Wednesday, with wet snow Thursday as cooler air is drawn back into the system. My thoughts are that it will be mostly a snow event with over 15cm likely. As I always say, time will tell.

This storm originates from Texas and is bringing north a tremendous amount of moisture. Yesterday blizzard conditions were reported from north Texas into the central Plains and Midwest. Some areas had over 40cm of snow, and hurricane force winds were reported in Amarillo, Texas with the snow. Meanwhile strong thunderstorms produced hail and damaging winds along the Gulf Coast from Louisiana to Florida. This storm has the potential to disrupt travel on Wednesday and Thursday on the busy Montreal to Windsor corridor.

Another storm for Ontario & Quebec

Montreal had nearly 10cm of wet snow that made travel a little tricky on Saturday. (ValleyWX)

Montreal enjoyed a mild weekend with wet snow off and on for most of it, and very little sunshine. Trudeau Airport had about 8cm of steady wet snow on Saturday, that was quite heavy at times. This morning it remains mild at -1C, but just cold enough for a layer of thin ice beneath the dusting of snow. We should see a few breaks in the cloud today as high pressure attempts to briefly build into the region. It will be short lived as a rather large and very complex storm is taking shape over Texas. This system will lift north towards the Great Lakes over the next several days and dominate our weather from late Tuesday until the end of the week. Today and Tuesday will be quiet in southern Quebec with mild late February highs of 1 to 3C and just a few flurries this morning.

By late Tuesday deep moisture will begin to surge across Ontario and Quebec from the Texas storm. It appears precipitation will fall as wet snow mixed with rain for most locations. Amounts will be very tricky to forecast with just enough warm air to mix the snow with rain in many locations. Specific amounts, type and duration of precipitation will be further complicated by a second storm that develops along the US east coast. Both system will provide the region with precipitation well into Thursday. At this time it looks like at least 15cm for Montreal and maybe more. Warnings may be required for a large portions of the region from Ontario into Quebec, Atlantic Canada and northern New York and New England. Winds will be gusty with the system especially along Lake Ontario and the St. Lawrence Valley.

More precipitation for snow weary Quebec

I need spring!

With March just around the corner, it appears we are well entrenched in winter 2012-2013. The wind has finally eased this morning after 48 hours of blowing snow, making me think I was back in Saskatchewan. Drifts are 2 and 3 feet high in open spaces with snowbanks towering over residential streets.The blowing snow was a nuisance in the city but very problematic on area highways, especially the 20 west to the Ontario border and the 15 and 30 on the south shore. Final accumulations from the two day event ranged from near 20cm (8 inches) in metro Montreal up to 40cm across the Townships and 60-100cm in the Gaspe region and eastern Quebec. This morning it is calm and rather mild compared to Thursday morning with a temperature of -6C. Today will be sunny and calm with mild highs of 0C (32F).

Snow blown by 60km/h west winds continued on Thursday afternoon on the West Island of Montreal.

We now await the next storm system moving from the central US plains into the Great Lakes. This storm is very strong bringing blizzard conditions across Kansas and Nebraska. It is however expected to weaken while a second system develops along the US east coast and moves well east of Cape Cod. Both storms will be far enough from Montreal as to not produce a major storm. However we are looking at snow developing Saturday and lasting into Sunday with 5-10cm (2-4 inches) expected, perhaps more once again across the south shore. It  will be breezy, but not like the intense wind we just had, perhaps in the 20-40km/h range. Temperature will be mild, so the snow will be wet, also cutting down on the blowing and drifting. More snow is expected next week as yet another storm heads towards the northeast.

Over 100cm snow in the Gaspe

Spring is out there somewhere, but it does not look like it on L'Ile Perrot with the mountains of snow in my neighborhood. I have not seen my lawn since early December. We are buried and if it was not for the two major January thaws we would have even more. (ValleyWX Photos)

This is not a storm, right? At least that is what I blogged yesterday, but it sure feels like one. Low pressure near Sydney, Nova Scotia, continues to pinwheel waves of snow across southwestern Quebec. Most times the snow has been light but often it is not. The result has been 15-20cm (6-8 inches) across most metro regions with over 30cm in the Townships and Green Mountains of Vermont. Officially Trudeau Airport had 11cm yesterday  but with the west wind gusting over 60km/h it has been difficult to measure at best. It looks like 15cm here on L'Ile Perrot, but I have drifts in the backyard over 2 feet. The wind has been relentless for the last 24 hours with blowing snow creating havoc on south shore highways, including the new Autoroute 30 that had to be closed in sections yesterday due to whiteout conditions. This morning there have already been several major accidents on area highways as the wind and blowing snow continue, now with biting cold at -14C (6F) and windchills down in the minus 20's in Montreal.

100cm of snow in the Gaspe
Other parts of the province have been hit much harder, with over 100cm (40 inches) of snow from back to back storms across the Gaspe region. Strong winds have whipped the snow into to high drifts closing many roads. The Gaspe Airport has had visibility under 0.5km since last evening. They recorded 27cm of snow yesterday, to go with the 60cm already this week. There is relief in sight as the low pressure will move into the north Atlantic and release its grip on the area. Skies will clear out for Friday and it will be fair and warmer, up to 0C in the bright late February sun. More stormy weather is expected this weekend with rain and snow. More on that later today.

Snowy week for Montreal

A burst of moderate snow on L'Ile Perrot last night left about 8cm on the ground. (ValleyWX)

While it is not a storm as such, there will be enough snow to shovel and plow over the next few days across southern Ontario and Quebec. A trough of low pressure swung across southern Quebec last night with a surprising burst of moderate snow between 7:30pm and around 11pm. Some locations reported as much as 8cm with 6cm officially at Trudeau Airport. That amounts to 2 or 3 inches in just a few hours. This morning the gusty northwest winds are blowing that snow around and they will continue most of the day up to 60km/h.

A large upper level low will slowly drift across eastern Ontario and southern Quebec well into Friday with periods of snow. The snow will be light most of the time with amounts in the 5-10cm range by late Thursday with higher totals across the snow belts of the Great Lakes and in the mountains north and southeast of Montreal. Friday looks fair at this time before another low and frontal system approaches the St. Lawrence Valley for Saturday. Temperatures will be slightly cooler today around -3C but warm to the freezing point for the balance of the week. Overnight lows will generally be mild around -5C.

Light to moderate snowfall for Ontario & Quebec

The power is coming back on in Atlantic Canada after a winter storm walloped the region with winds in excess of 100km/h and over 30cm of snow on Sunday and Monday. Heavy rain and high surf affected  Nova Scotia. Search efforts also continue for the Miss Ally, a 13 metre fishing boat that went missing during the height of the storm late Sunday off the Nova Scotia coast with 5 on board. (CBC)

A series of low pressure areas will bring a mixed bag of winter weather to portions of Ontario and Quebec over the next few days. Today we have low pressure lifting northeast across the central Great Lakes and into Ontario. This system will push a warm front up the St. Lawrence Valley later today with light snow spreading into eastern Ontario and Montreal by late today. The snow will continue overnight and mix with some rain or freezing rain along the US border. Temperatures will warm to near the freezing point in southern Quebec and above south of the border into New York and west into the GTA. Snowfall amounts will range from a trace near the US border to around 5cm in Montreal and as much as 10cm north and west of the city. A strong cold front will cross Ontario today and into Quebec by Wednesday with gusty winds, up to 90km/h in Ontario and 60km/h in southern Quebec. Some decent snow showers are expected along the front with blowing snow and perhaps another couple of centimeters accumulation. Temperatures will cool off behind the front with highs of -3C on Wednesday. The balance of the week looks unsettled with more snow flurries and temperatures close to the normal high of  -3C.

Atlantic Canada & Gaspe snowstorm update

Here is an update on the current snowstorm affecting Atlantic Canada, along with a great satellite photo of the storm. Montreal is on the western edge of the system with just some high clouds to the east, we will however have gusty winds up to 60km/h. Combine that with overnight lows of -16C, and windchill values will be as cold as -29C for the morning commute on Monday.

Snowstorm Update - Canadian Weather Blog Weather Blog

Snowstorm for eastern Quebec

Light snow is falling across eastern portions of the island of Montreal this morning as a clipper system races off to the east. L'Ile Perrot had around 2cm overnight, most of that falling in a burst just before 6am. Local roads are slippery but temperatures are very mild, right at 0C (32F), so melting is occurring on the main highways. Skies will be cloudy for the most part today as winds increase out of the west and temperatures level off or slowly fall. Tonight should be clear and cooler than it has been across the region with lows on either side of -10C. The weekend for the Montreal metro region and points west looks great with lots of sunshine, but chilly. Off to the east and southeast it will be a different story as a coastal low takes shape and moves northeast towards Atlantic Canada. This storm will be well offshore so I don't expect anything for Montreal on Sunday at this time, except a passing cloud or two. Some light snow is forecast across New England, but amounts will be light. The heaviest snow and strongest winds will occur in eastern Quebec and across New Brunswick where up to 20cm is possible.

HYDRO-QUEBEC

Last weekends snowstorm in New England prompted Hydro-Quebec to send 50 crews to Massachusetts to help restore power to more than 600,000 homes and businesses. There is always so much negative attention given to the province of Quebec in the media. Yesterday this brief note was published in the Montreal Gazette, so I though I would share it here. These guys work long hours in difficult and dangerous conditions to keep the power on. Kudos to them, nice job.

As a resident of Wareham, Massachusetts, U.S.A., I would like to extend my sincere thanks for all the help Hydro-Québec crews gave us during our blizzard and severe electrical outage this past weekend! What a great feeling it is to know that we can all come together across borders and cultures to help one another. Your crews were very professional and you were well represented. It’s something me and my family will not soon forget!

Mild with flurries for Ontario & Quebec

Weak high pressure will try to clear skies out today but I think low clouds and moisture will limit any sunshine we see here in southern Quebec. On Tuesday and overnight we had periods of very light snow with a trace to as much as 1cm here on L'Ile Perrot. It is mild with the cloud cover keeping the temperatures in the -2C range. Highs today will be up above freezing to 2C. Thursday will be partly cloudy and a touch cooler with highs generally below freezing at -1C. By Friday another clipper system will affect southern Ontario and Quebec with some light snow and rain. As a rule these type of systems produce up to 5cm of snow or rain and not much more. The weekend at this time looks fair with near normal temperatures, but we are watching the potential for another east coast storm once again by Sunday. This will need to be monitored as several scenarios are at play at the moment. The system could hug the coast or move well out into the Atlantic and miss us entirely.

Unsettled weather week ahead

The freezing rain and rain are over for the Montreal area as low pressure continues to move well north and east of the city this morning. Yesterday, cold air hung around longer than expected in the St. Lawrence Valley and as a result we had several hours of freezing rain late in the day. Conditions on the Island of Montreal were icy but not as bad as off island highways. Highway 30 across the south shore in Beauharnois was the scene of several ditched cars during the evening rush hour. Temperatures finally did warm above freezing late in the evening, all the way up to 4C, the first above zero reading this month. We are still above the freezing point at 1C (33F) this morning with several snow flurries around. There are some heavier snow showers in the Ottawa Valley along an advancing cold front, so we may see 1-2cm today. Some heavier snow will be confined to the higher elevations of the Green Mountains and the Townships as well as the snowbelt region along Interstate 81 east of Lake Ontario.

Temperatures will stay right where they are all day. Under partly cloudy skies lows will be around -10C and up to -1C on Wednesday. Most of the week looks unsettled with lots of clouds and a chance of light snow. There are several potential storms in our future but at this time the tracks look to be to south to affect Montreal. We will have to watch and wait.

From the Blizzard of 2013 to rain & ice

Coastal damage in Nova Scotia from the Blizzard of 2013

The snow is over as the Blizzard of 2013 has swept into the North Atlantic this morning. In its wake we have damaged coastal infrastructure, thousands without power and 1-3 feet of snow from Ontario and southern Quebec across New England, Atlantic Canada and finally Newfoundland. Montreal remained on the northern edge of the storm with 15-25cm (6-10 inches ) across the city. Power is slowly being restored to the nearly 1 million customers that lost it, including 650,000 in New England. Utility crews from across the region, including 65 teams from Hydro Quebec are in New England helping to restore power. So far more than half have been brought back on the grid.

The storm took a parting shot at Newfoundland yesterday with heavy snow and hurricane force winds up to 145km/h. The snow fell fast and furious with 53cm recorded at Gander.

This morning we await the next system, a low pressure area moving across the central Great Lakes. It will produce snow and wind across Minnesota, Wisconsin and into northwest Ontario. Montreal and eastern Ontario will remain on the warm side of the storm with light snow and freezing rain changing to rain this afternoon. We are currently at -10C but will warm above freeing to 2C (36F) by late this afternoon. Freezing rain warnings are in effect for the Ottawa Valley and eastern Ontario as well as points north of Montreal. School bus service for the second consecutive work day has been cancelled in eastern Ontario. Look for any precipitation to change back to flurries tonight before ending. Overnight lows will be in the -1C range. Amounts today will be light with up to 2cm of snow and perhaps 5mm of rain.

Awesome New England Blizzard

Via Twitter @radiomelissa - Taunton, Mass this morning.

High tide in Hampton Beach this morning with the surf lapping against the boardwalk in the midst of a raging blizzard.

I like this entry from the National Weather Service office in Gray, Maine this morning:  INTENSE MESOSCALE BANDING HAS SET UP ALONG THE COASTAL PLAIN EARLY THIS MORNING ALONG WITH INCREASING WINDS. CONDITIONS AT THE OFFICE HERE IN GRAY MAINE HAVE BEEN NEARLY UNPRECEDENTED. SNOWFALL RATES HAVE BEEN 2-4 INCHES PER HOUR WITH GUSTS 40-50 MPH. NEEDLESS TO SAY THIS IS A DANGEROUS AND HISTORIC BLIZZARD. TRAVEL EARLY THIS MORNING WILL BE VERY DIFFICULT AT BEST AND IMPOSSIBLE AT TIMES. TOTALS WILL BE 1-3 FEET FOR MOST OF THE AREA WITH SIGNIFICANT DRIFTING. TRAVEL IS HIGHLY DISCOURAGED THIS MORNING. 

From Toronto across extreme southwest Quebec and into New England those two powerful winter storms have left their mark. Yesterday heavy snow fell in Ontario, up to 40cm around the GTA with 25cm in downtown Toronto, 25cm at Ottawa and 20cm at Kemptville. The wind and snow caused several major accidents from Montreal to Toronto with three fatalities reported, 1 in Quebec and two in eastern Ontario on the 401. In Montreal dry air entered the system from the east as the energy transferred from the Great Lakes low to the coastal storm. As this happened precipitation abruptly shut off in the region with 20cm (8 inches) measured here on L'Ile Perrot.

Such was not the case across southern New England where heavy snow, thunder and lightning and hurricane force winds created a massive weather emergency last night. Highways were closed across a four state region with a travel ban is in place as a result of snow totals in some cases up to 30 inches. Portland, Maine set a record for the largest one day storm ever at  just over 29 inches. Wind gusts were reported between 70 and 90 mph across southeast Massachusetts and the Cape. Nearly 600,000 homes are without power across Massachusetts, Connecticut, Rhode Island, Maine and parts of Long Island. The storm is also producing a dangerous surge at high tide this morning, flooding portions of the coast from southeast Massachusetts into New Hampshire and southern Maine.

The storm is now pounding Nova Scotia, PEI and extreme southern New Brunswick with a high storm surge and between 30- 60cm of wind driven snow. The snow is over for Montreal, it will be breezy and cold today with some drifting snow. Winds will abate tonight and it will be cold down to -18C (0F).

Classic Nor'Easter - Montreal on the northern edge

Radar this morning clearly showing both storms as they converge on New England. Heavy snow is falling from Toronto across Ontario to the Quebec border. Meanwhile more heavy precipitation is moving north from the middle Atlantic.

Quickly here is the latest on the winter storm affecting Ontario and southern Quebec. We have winter storm warnings posted from Montreal southwest to Windsor. They have been extended northward to include the Ottawa Valley. Basically we are looking at a very cold day with gusty northeast winds up to 60km/h and lots of snow and blowing snow. Accumulations will be in the order of 10cm in the northern regions to 25 or 30cm towards the US border and Lake Ontario. In metro Montreal 10cm over the island and Laval with 15cm from L'Ile Perrot south and up to 25cm near the New York border.

By tonight this low will become absorbed by a much larger system that is taking shape this morning along the North Carolina coast. That storm will move towards Cape Cod while deepening rapidly. This will be a major blizzard for New England and Atlantic Canada with 100km/h (60mph) winds and 1 to 2 feet of snow. Already this morning delays and cancellations are pouring in. Coastal flooding will be a big issue from Massachusetts along the coasts of New Hampshire, Maine and Nova Scotia. Large, damaging waves will surge in along the coast.

With the snow affecting such a large area in the east, air travel will be severely disrupted - call ahead. Also, if you are thinking about driving to Ottawa, Toronto or Boston today, I would strongly advise that you don't.

This will be an historic storm in places just not in southern Quebec or Ontario. It will however be a snowstorm. Here is the break down as it stands at 6:30 pm this evening. Low pressure near Chicago will move east towards Lake Erie and pass south of the region. It will begin to interact with a moist rapidly developing storm over the Gulf of Mexico as it moves northeast towards Long Island. The system will deepen rapidly into a major blizzard for southern and interior New England. Strong winds up to hurricane force (74mph) and 1 to 2 feet (30-60cm) of snow is forecast for those areas.

Locally we have a winter storm warning in effect from the south shore of Montreal to the US border and southwest along the St. Lawrence River to Lake Ontario and the GTA. Storm totals from Montreal south will be in the 10-20cm (4-8 inch) range. From Montreal north more like 5-15cm (2-6 inch). All regions will have very cold temperatures and strong northeast winds creating dangerous windchill values and blowing snow reducing visibility to under 1km at times. This storm will have disruptive effects on air travel across the entire east as well as road travel south and southwest of Montreal. Travel in those areas is not advised on Friday. If you have a flight to Toronto, New York or Boston, call ahead.

That is it for now I will update more details later on this evening.

Snowstorm for portions of Quebec, Ontario & NE

From AccuWeather, snow accumulations expected from storm 1.

There is plenty of weather to talk about this morning as two separate areas of low pressure are forecast to come together off the east coast of the US and produce a major storm for New England and Atlantic Canada. I will try to bring some order to this, as always when I am excited about the weather, I tend to be all over the place with the blog!

We will start with storm one over Texas that will move towards Lake Erie later today. This system has prompted winter storm warnings for southern Ontario from Windsor up towards Kingston. Snow will start tonight and become heavy on Friday. Amounts in the order of 25cm are forecast for the region with perhaps 15cm for the Ottawa Valley. Travel on Friday will be very difficult along the 401 corridor and especially in the GTA.

The strom could be historic in southern New England including Boston and the Cape.

By Friday a potent storm will begin developing near North Carolina and this system will begin to absorb the fist low. It will move northeast towards Cape Cod while bombing out. This type of storm can loose as much as 24mb of pressure in 24 hours as it deepens rapidly. The intense low pressure area may be historic in places along the I-95 corridor from Providence up towards Portland. Heavy snow, strong winds up to hurricane force in places, coastal flooding and even thunder are forecast from Friday afternoon into Saturday morning. This storm will produce 1-2 feet of snow in a wide swath from southern New England north and west towards the Adirondacks and southern Quebec. For Montreal expect a few centimetres/inches of snow from the first storm from late tonight into Friday morning. There may be a lull in the snow before a second wave arrives from the southeast by late Friday. By Saturday morning we could be looking at 25cm (10 inches) of snow from the metro area south with more along the US border and into the Townships. No warnings are in place here at this time. A winter storm watch is in effect for the US side of the St. Lawrence Valley as well as northern New York and all of Vermont. There are still more details to iron out, but make no mistake whether you are planning to travel by car or air Friday, it will be very difficult across all of the east.

I will update this storm as the day moves along on Twitter with a full update by 7pm this evening.

Potential storm for Friday

Another weak clipper system is affecting southern Quebec this morning with a few flurries giving a dusting of snow. It will turn windy with clearing skies by mid-afternoon with temperatures leveling off around -8C. Tonight will be clear and cold with lows down to -21C in Montreal, colder in the burbs. Thursday will feature increasing and lowering clouds as the day progresses with very cold highs of -17C and an increasing northeast wind making it feel damp and chilly.

From AccuWeather.com

We then have a rather complex situation setting up with two low pressure areas expected to affect southern and eastern Ontario, Quebec, New England and eventually Atlantic Canada. Light snow will begin in southwest Ontario early Thursday and reach the Ottawa Valley and Quebec border by late in the day. The snow is being generated by the first system a clipper from out west that will produce about 5-10cm of snow for most locations. The snow will become enhanced Thursday night and especially Friday as the first low begins to interact with a developing coastal low near the Outer Banks of North Carolina. This system will become the main storm, rapidly deepen and move to Cape Cod by late Saturday. This will result in a significant snowfall for many portions of our region Friday. The exact amounts and where warnings may be required still needs some tweaking. Currently a Winter Storm Watch is posted for southern New England. We will see more watches and warnings as the forecast becomes a little more clear. I will post another update later today.

Cold start in Montreal - storm by Friday?

Impressive Environment Canada image of large storm swirling off the coast of Newfoundland on Monday.

Clear skies, calm winds and a fresh coating of snow have all helped the temperature drop rapidly to -23C here at my home on L'Ile Perrot this morning. It is a little "warmer" at Trudeau Airport at -19C. Temperatures will climb nicely today under bright sunshine with little wind to highs of around -8C. Clouds will increase later today as a weak clipper system slides down the St. Lawrence Valley. A period of very light snow is expected after midnight, much the same as this past weekend. Expect 1-2cm and not much more than that, just enough to coat the roads again. Skies will clear out Wednesday and it will be chilly once again.

Our weather pattern will then become a little more active heading into Thursday. Low pressure from the west will attempt to merge with energy along the eastern seaboard to produce snow by late Thursday into Friday. There are many different computer generated scenarios at this time but basically expect at least 10cm of snow from the GTA towards Montreal and Ottawa. If we have a merging of the two systems we could be looking at a larger coastal storm with perhaps more snow for Montreal. Once that clears out the weekend looks sunny and seasonable before another complex storm system takes aim at the region into Monday with more snow and mixed precipitation.

Yesterday a large and very deep coastal low with a pressure reading as low as 962mb affected portions of Atlantic Canada. Winds gusted up to 140km/h at Sagona Island, Newfoundland and 100km/h at Sable Isalnd, Nova Scotia. Halifax had over 20cm of snow while parts of the south coast had over 40mm of rain.

A little light snow

Light snow and gusty winds Saturday created icy highways in and around Montreal.

It is another chilly morning in Montreal after a cold weekend with a current temperature of -13C. We will settle into some typical early February weather to start the week. A cold front will pass across the region this morning with a few flurries. Behind the front, winds will increase out of the west and gust between 40-60km/h which will level off the temperatures around -9C. Increasing winds will lower the windchill values and also create some blowing snow, especially off island to the south and west. We saw on the weekend how easily even a little snow can get blown around and ice up highways after the 2cm on Saturday.

Other areas up the St. Lawrence Valley near Brockville and over to Kingston reported heavy snow as squalls moved north off Lake Ontario. Up to 15cm of snow fell around Kingston in only a few hours Sunday morning.

Once skies clear this morning we will have mainly sunny skies. Tonight will be clear and cold with lows down to -20C. Tuesday looks sunny and cold with highs near -10C. The next threat for snow will come late Thursday and Friday when, depending on which model you choose, we could be in for a storm or another 1 to 2cm snow event like Saturday. Stay tuned!

Groundhog Day 2013 - shadow for Sam NO shadow for Phil

Our groundhogs are at odds again as Shubenacadie Sam in Nova Scotia has seen his shadow and is predicting a long road ahead to spring. Meanwhile in a cold Punxsutawney, Pennsylvania, Phil did not see any shadow and has proclaimed an early spring is upon us. This year, both are probably right, it has been that kind of a winter as we all know. In Montreal this morning -17C (2F), during a week that saw a record high and a 10C (50F) day. We await Wiarton Willie in the cold and snow of Ontario....

Damage & power outages from Montreal wind storm

The wind is still gusty this morning in the 30-40km/h range in Montreal, but well down from the 60-80km/h sustained winds of Thursday. Departing low pressure responsible for all kinds of damage and injuries across eastern North America has finally moved well east of the area and off the eastern coast. In its wake we have a blustery and cold day with temperatures remaining fairly close to where they are now, -14C. This is a far cry from the record warmth of this week and about 25 degrees colder than 24 hours ago. Yesterday the wind peaked in gusts of 85km/h at Trudeau Airport but as high as 100km/h across the South Shore of the St. Lawrence River. The wind cut power to nearly 110,000 homes and businesses in Southern Quebec. It also caused structural damage around the region including car shelters blown over, a chimney toppled in downtown Montreal, trees knocked down and even a roof peeled back from a home here on L'Ile Perrot. The wind also played havoc with area traffic blowing some vehicles off the roads on Highway 25 north of Montreal, and knocking a transport onto its side on Highway 40 in Vaudreuil/Dorion.

Winds will diminish today as skies remain cloudy with a few flurries. Temperatures will gain maybe a degree or two but not much more before dropping to -18C tonight. The weekend will be cloudy with a few flurries or snow showers at times and chilly. If your travels take you anywhere around the Great Lakes be advised there is lots of snow squall activity. The squalls have been strong where they have occurred creating sudden white out conditions on Interstates 81 and 90 as well as the 401. Yesterday a squall in Detroit on I-75 resulted in a massive pile up and three fatalities. Drive with caution, be safe.
