As Canadians we talk about the weather relentlessly, I just talk about it a little more! I hope to provide useful information to my family, friends and all those who simply enjoy talking about the weather. My primary region of concern is the St. Lawrence Valley of Quebec, Ontario, and New York, as well as our neighbouring regions. This Blog is dedicated to my late father for inspiring my interest in weather, and to my "all weather" pup Bella.

Unsettled start to week

Today we are looking at more showery weather here in southern Quebec and extending into eastern Ontario and New England. Stubborn low pressure continues to spin east of Cape Cod feeding the area with a cool northeast marine air mass. We lucked out yesterday in Montreal with gusty showers all around us, but here in the city mostly sunny and mild most of the day. We are not so lucky this morning as the temperature is a very chilly 11C with a gusty northeast wind to 25km/h. Those winds will increase in the St. Lawrence Valley to between 30 and 50km/h today. So it will be cool and showery most of the day with highs no better than 16C. The good news is we should have a gradual warming trend by the end of the week with much warmer summer type weather by next weekend.
Over this past weekend, very heavy rain fell across portions of New England, primarily Maine and New Hampshire, areas that were already affected by major flooding last week. As much as 2 to 3 inches of rain soaked the area. Trust me it was raining hard, I drove home in it on Saturday. In addition the rain that coastal system has caused flooding and high surf from Massachusetts all the way northeast into Newfoundland including coastal areas of eastern Quebec. Watches and warnings are in place.

Rainy weekend
| Sunrise this morning here in Hampton Beach. ValleyWX Pic |
The Seacoast: The forecast is the same here on the New England coast. The other factor here however will be high astronomical tides combined with the storm that could produce coastal flooding. A special weather statement has been posted and warnings may be needed. This morning was spectacular with a beautiful sunrise at 5:02 that I captured above.

After the big flood - the big clean up
Crews continue to clean up and assess the damage caused by yesterdays thunderstorms in Montreal and across Ontario and New England.
Heavy rain produced massive flooding in Montreal across the south shore and into Vermont and New Hampshire. Nearly 70mm of rain or close to 3" fell in less than 1 hour swamping the sewer system and flooding roads and stores. Several schools are closed today because of flooding. While no estimate is ready yet damage will certainly run into the millions. You will notice no data on my weather station, the storm took it out and it won 't be fixed until the weekend. Here on the Seacoast of New Hampshire a marine layer of cool air forced the heavy rain and flooding into central and southwest New Hampshire where roads were washed out. In New York state, 3.5" hail was reported, massive for that part of the country.

Major flooding hits Montreal
![]() |
| Major flooding hit downtown Montreal around 5pm tonight. (CJAD) |
As forecast earlier today, big thunderstorms swept the island of Montreal this afternoon causing major flooding downtown. Nearly 50mm of rain fell on the city in under 1 hour. The rain overwhelmed the Montreal sewer system flooding major roads and downtown businesses. Several downtown stores received flooding and were forced to close. The Ville Marie tunnel eastbound was closed as well as portions of Highways 138 and 20. Tornado warnings were in effect for the border areas of Lacolle and the Richelieu Valley. Flooding also occurred in Vermont and New York, and tornado warnings were in effect for parts of Vermont. The storms are farther off to the southeast now, and I am waiting for them here in coastal New Hampshire.
Here in Maine and New Hampshire, we had dense fog all day as winds blew inland off the 10C (50F) Atlantic Ocean and ran into the warm and humid air. The cooler air here at the coast should knock down the storms quite a bit as they arrive by midnight.
Big storms today
I am back online after a night with no Internet, very hard for a techno weather geek. Anyway I will be brief, just a heads up for Montreal, eastern Ontario and New England. A warm front has become the focus for severe slow moving thunderstorms. Watches are posted all day including an elevated risk for a tornado. The big threat will be heavy flooding rain and large hail. It will be warm & humid. Be safe and check back often to the links on the left side for updated warnings.

On top of the world... or at least New England
| Here I am measuring the wind on the summit of Mount Washington today. It was a rare day with visibility over 70 miles as you can see (ValleyWX pic). |
I have taken the weather show on the road again, this time not too far from home, in New Hampshire. Today I went to the top of Mount Washington to visit the Weather Observatory. At 6288 feet, Mt Washington is the highest peak in New England. The weather can be downright treacherous, but on this day it was near perfect. The sun was shinning and the wind was light, by Mt W standards. Remember this was the location of one of the strongest wind gusts in the world, 231 mph in April 1934.
The wind regularly surpasses 100 mph, and temperatures are often below -18C (0F). On this day the temperature was 24C (76F) at the base, and 10C (50F) at the summit, relatively mild for a place where snow has fallen every month of the year. The wind speed at 12:50pm was 28 mph gusting to 36mph producing a windchill of 4C (40F). It was a thrill to climb the 8 mile Auto Road with our guide Mike. The location is a must see for anyone who is interested in weather. You can drive it yourself or save your brakes and your breakfast (the road is very narrow) and take one of the "coaches" or well equipped vans. Coaches have been carrying visitors up to the summit since 1861. At the time it was a horse and carriage but that has thankfully evolved. How lucky were we to have sunshine? Each year fog and clouds limit the visibility on over 300 days, most times under 1 mile. Today the visibility was over 70 miles allowing us to see all the way to Mount Orford in southern Quebec. More tomorrow when I head south to the Atlantic coast.
Locally across southern Quebec and New England, strong thunderstorms may fire up again by late Monday. On Friday night 2 tornadoes occurred northwest of Montreal. It will be an unsettled week as a warm front remains over the region.
Tropical storm Beryl is nearing the coast with 70 mph winds at this hour. Heavy rain, power outages and coastal flooding are likely tonight into Monday from South Carolina to northern Florida.

Strong storms cross Montreal
| Awesome storm photo from Ottawa this evening. Photo by @MSC_63 via The Weather Network. |
A fierce line of thunderstorms has crossed the Ottawa Valley and southern Quebec and is now affecting the south shore and points east. A tornado warning was issued for Montreal and surrounding regions after two separate storm cells showed signs of rotation. I observed both storms as long as daylight would allow me and saw no rotation. As best I can tell the strongest portion of the storms passed very close to my location here on L'Ile Perrot. Winds gusted to over 30km/h at my home and up to 55km/h at the airport. They may have been higher here on L'Ile Perrot but data is only sent to my computer every 15 seconds. Heavy rain was the big story here with 23mm or just under 1 inch in less than 30 minutes. The tornado warning has expired for Montreal Island but a severe thunderstorm watch remains posted until midnight. I imagine that will expire shortly as well as most of the activity is off to the east. Ottawa also had heavy storms with power outages reported. According to CFRA in Ottawa, an 18 year old man is in critical condition after being struck by lightning near Vincent Massey Park during the storm.
Strong thunderstorms possible

On the other side of the country it is cold across the prairies with Regina sitting at 1C this morning and flurries in the air. Snow also fell across far northwest Ontario. Heavy rain is forecast from Montana across Saskatchewan over the weekend with as much as 25mm. Where they could use the rain is near Kirkland Lake, Ontario. A massive forest fire burning about 2700 hectares continues to test firefighters. Winds have been strong and temperatures warm under a nearly stationary high pressure area. Dense smoke from the blaze is affecting the Timmins area where a state of emergency has been declared.
Tropics: It is not unheard of the have such an early active tropical season in the Atlantic, but it is rare. Last weekend it was tropical storm Alberto which thankfully moved out to sea and dissipated. This week we are looking at an elongated area of low pressure off the coast of Florida that has deluged the state this week. Nearly 10 inches of rain fell in south Florida with major flooding. The system is forecast to develop into a tropical storm this weekend and be named Beryl. The storm will move northeast and then back west towards the beaches of Georgia and the Carolina's. Remember it is the busy Memorial Day Weekend and the area will be very crowded. All interests should monitor the latest forecast for the area available HERE.

Thunder possible today & Friday
Once the clouds lifted on Wednesday, it was actually a rather pleasant day with sunshine and highs of 22C. Today we started off at a rather muggy 13C at 6am that has rapidly risen to 19C here on L'Ile Perrot. It will be a very warm and humid day with a 30 percent chance of afternoon showers and perhaps a rumble of thunder. Temperatures will try to hit 30C, already for the second time this year and we are only in May. A cold front will approach the area on Friday with a good chance of showers and thunderstorms likely. Temperatures will again be warm on Friday to 27C before drier and cooler air moves in for the weekend. Temperatures will cool into the mid 20's with sunshine for Saturday. Clouds will increase on Sunday with a chance of some showers.

It will be a very mild and humid week with some clouds and fog around this morning, giving way to sunshine and high temperatures near 23C today. Thursday into this upcoming weekend will be warm and a touch on the humid side with some showers and perhaps a thunderstorm by late Friday. High temperatures will be near 28C for highs and the upper teens for lows, well above normal for May.

After the sun - heavy rain
SEVERE THUNDERSTORM WATCH - ENDED
Environment Canada at 3:05pm has posted a thunderstorm watch for the Montreal metro area and points southwest along the St. Lawrence River, as well as the Townships. Slow moving showers and thunderstorms with heavy rain are developing in Ontario and New York. The storms are moving slowly northeast along a cold front towards southern Quebec. Already 20mm has fallen on L'Ile Perrot. Storm totals will be in the 40-50mm range, or up to 2 inches. The storms will taper off by this evening.

Record high for Montreal
What an incredible holiday weekend it has been weather wise across southern Quebec and eastern Ontario. Temperatures under light winds and abundant sunshine soared to record highs today making it the third month in a row this spring that we have had record highs well into the summer range. The high here on L'Ile Perrot was 32C (90F). St Anicet southwest of the metro region was 34C (94F), while Montreal reached just over 31.2C (89F) beating the record of 31.1 set in 1975. Kemptville, Ontario also reached 31C breaking their record of 30C set in 1998. The warm air will remain in place for Victoria Day Monday but with a few clouds and highs a little cooler around 28C. A cold front with showers and thunderstorms arrives late Monday and into Tuesday with temperatures closer to normal for May.
Tropical Storm Alberto: Alberto continues to meander just off the Georgia and South Carolina coast with very little impact on land except for some rough surf and clouds. All watches have been lowered at this time. Alberto is drifting southwest but is expected to accelerate off to the northeast away from the coast on Monday. The storm has 45mph winds, but is in an area of strong wind sheer and colder water temperatures. No change is strength is expected before the storm moves away from land and dissipates by Thursday. Interests from northeast Florida to the Outer Banks should continue to monitor Alberto.

Spectacular Weekend

Temperatures will warm quickly today under bright sunshine with highs near 23C. Saturday we are looking at 26C and up to 30C both Sunday and Monday. On Monday stubborn low pressure that will be hanging along the Atlantic Coast from the Carolina's to New England this weekend, may send a few clouds into the extreme southern portion of Quebec. I don't think we will see any precipitation from this system.

Cool and dry
| Thunderstorms rolling across Lake Champlain into Burlington, Vermont on Wednesday. (Burlington Free Press photo) |
Numerous weather warnings were issued by both Environment Canada and the National Weather Service on Wednesday. The thunderstorms produced lots of severe weather, mostly in the form of hail. There were dozens of reports of pea and marble size hail across southern Quebec including south shore St. Hubert where 2cm hail fell at the airport along with 80km/h winds.. The storms missed my location here on L'Ile Perrot with no rain recorded at all. The strongest storms affected the north end of Montreal into Laval. Another area of very strong storms developed rapidly in Clinton County in upstate New York, affecting Champlain and Lacolle in the border region. They then moved north and east into the Richelieu Valley. No storms are forecast through this upcoming Victoria Long Weekend with sunshine and warming temperatures both Saturday and Sunday. Holiday Monday is a little up in the air right now as the timing of another cold front comes into play. There will likely be a mix of sun and clouds along with showers and storms.

Strong thunderstorms today
| From weather.com, strong storms are possible today from the St. Lawrence Valley into New England and New York. |
5pm Update: Most of the activity with today's cold front is well east of Montreal and into Vermont and eastern New England. The watch for Montreal and points west has been allowed to expire. Some strong storms did occur, especially in the north end of Montreal and the Richelieu Valley. Some hail and heavy rain was observed. Here on the West Island we had some gusty showers with winds over 55km/h, but no thunder or lightning. I have yet to hear thunder this year.
We have a very humid and foggy morning in Montreal today as an unstable, mild and moist air mass is in place. Temperatures are around 13C here on L'Ile Perrot with a forecast high of 22C. The fog will burn off by mid morning and sunshine and warm temperatures are expected into the early afternoon. A strong cold front with a history of severe weather is forecast to move into Eastern Ontario around 2pm and sweep southeast across the St. Lawrence Valley and into upstate New York by 6pm. Yesterday this same front prompted tornado and severe thunderstorm warnings for northwest Ontario including Timmins. Along and ahead of the front look for showers and the occasional strong thunderstorm to develop. The storms will be capable of strong winds and even hail. The cold front should clear the area overnight with clearing skies on Thursday and much drier and cooler weather. At this time the long Victoria Day weekend looks awesome with sunshine and temperatures warming to the high 20's by Monday.

Summer humidity returns
Remember humidity? Well it is back. This morning we have a front just south of the St. Lawrence Valley that is pushing some clouds and showers across the region. It is muggy and will stay that way for the next 24 to 36 hours. On Wednesday a cold front will give us a risk of showers and thunderstorms. Temperatures will be mild, 20 to 23C unless we see some sunshine.
The Pacific tropical season starts today, May 15. Tropical storm Aletta formed a few hours before that last evening. The storm is gaining strength in the Eastern Pacific, 645 miles southwest of the Mexican coast. Winds are 40 mph, and the storm is no threat to land.

Warm sunshine today
That certainly was close to a perfect weekend for early May. Plenty of sun on Saturday helped sneak temperatures up to 26C around Montreal or very close to 80F. Some much needed showers late Saturday night helped to green up the grass and open the tulips for what turned out to be a glorious Mother's Day. The showers ended just after sunrise followed by rapid clearing by noon. That front has now slipped south of the border across the Adirondacks of New York and has become nearly stationary. You do not have to drive far down Interstate 87 to hit rain and lots of it. The front will remain the focus of steady rainfall across central and southern New York and New England before it lifts back north as a warm front by late Tuesday bringing southern Quebec more showers and thunderstorms. Until then it will be another sunny and warm day today with highs in the mid 20's. Once the threat for showers ends by Wednesday, warmer temperatures and sunshine will develop and last into next weekend.
Friday, May 11, 2012
Weekend Update
Skies are beginning to break up a little in Montreal this morning as a front associated with strong low pressure in Atlantic Canada, slides east of the city. Look for a sprinkle or two this morning followed by clearing skies. The warm May sun will rapidly warm temperature to 17C or 18C today. Clear skies tonight will allow for some frost well away from the metro region across the Townships and into Vermont. Saturday will be a glorious day with warm sunshine pushing temperatures into the 20's. That trend will continue into Sunday with just a hint of a front moving across the St. Lawrence Valley overnight Saturday. Again perhaps a cloud or sprinkle but skies will clear rapidly and it will be a sunny Mother's Day. Temperatures will be a little cooler Sunday, around 17C. Good news to start next week, temperatures look warm and the forecast looks dry. We will have to watch low pressure over Texas that is producing major flooding to an area that was in a severe drought, go figure. Anyway that system will move northeast towards the middle Atlantic and could play a role in our weather during the middle part of next week.

More clouds and showers
| Wild photo of waterspouts off Grand Island on Louisiana's Gulf Coast on Wednesday. (NOLA.com) |
Yesterday Montreal managed a humid high of 19C. There were numerous showers and thunderstorms across Ontario and into the Laurentians north and west of Montreal but they managed to avoid the city. This morning we have low pressure lifting north along the Atlantic Coast with rain falling rather heavily from eastern New England into the Maritimes. Some locations will see close to 75mm (3 inches) of rain today. Numerous locations in Coastal Massachusetts and New Hampshire had at least that overnight. We will remain under clouds from that system but the precipitation should stay east of the city. Gusty northwest winds and clouds will keep high temperatures down to 15C today. A few showers are possible overnight tonight and into Friday before skies clear out. We are looking at a mostly sunny and mild weekend, but we may see a few clouds and perhaps a stray shower late Saturday night.
We did have some active weather yesterday with small hail in Ontario during afternoon thunderstorms. There was also some waterspouts (tornadoes over water) in coastal Louisiana along Grand Island on the Gulf Coast. I posted a spectacular shot from NOLA.com above.

Awesome Monday - rainy week
| The super moon rising over Montreal Saturday. (The Weather Network) |
It was a busy weather weekend across the country with snow and wind in southwest Saskatchewan and in the Calgary area with as much as 10cm reported. In Montreal we had a beautiful but chilly weekend with ideal conditions to watch the super moon rise over the city on Saturday night. The full flower moon was 14% larger and 30% brighter than normal. The cosmic show was brought about by what NASA described as the moons closest approach to earth while being in the full phase.

Weekend Update
We are 0 for 4 in the sunshine department for May thus far. It has been a chilly and at times showery start to the month. Yesterday some warm air nosed into extreme southern Ontario with the temperature soaring to 31C in Windsor. Meanwhile eastern Ontario and Montreal remained as we are this morning, on the cool side of that warm front. More showers are occurring with the occasional rumble of thunder along the US border. Temperatures are in the low teens. The front should pass east of Montreal and allow for some partial clearing and warmer temperatures up to 22C today. A cold front will pass across the area this evening with some scattered showers and may a thunderstorm, again close to the US border. Skies will clear overnight and it will be a sunny but cool weekend with highs around 15C and lows close to 2C. There may even be some frost again Saturday night. Have agreat weekend.

Dense fog
Temperatures are a little milder this morning, but not warm enough to turn off the heat for good. Seems odd this year that we have the heat on in May and the A/C was on back in March. High pressure this morning is trying to nudge into the region after the showers and prolonged drizzle of yesterday and last night. Clouds are still thick with lots of fog across southern Quebec and Ontario this morning, and that will take some time to burn off. Once it does we can expect some partial sunshine and warmer temperatures close to 15C. We will add a few more degrees to that high tomorrow and Friday as we approach 20C. Sadly we will lose the sunshine as a warm front slowly moves across the region with showers and thunderstorms, followed by a cold front Friday and more thunderstorms. The weekend at this time looks fairly mild with a mix of cloud and sun. The storms will be of the garden variety in Quebec, but they could approach severe limits in southwest Ontario with heavy rain, gusty winds and dangerous lightning.

May flowers
The tulips and trees are popping everywhere this morning as a light rain helps them to burst onto the scene. A weather system passing to our south has pushed an area of showers across southern Quebec including Montreal this morning. I have measured about 5mm overnight with the heaviest rain remaining south of the border. Light rain will last until the early afternoon before tapering off. Cloud cover will keep the temperatures a little cooler than yesterday in the 10C range. Skies will try to clear out tomorrow, but I think lots of clouds will remain and we may even have a few sprinkles. A warm front is expected to approach the region late in the day and try top pass across the region on Thursday. We may see some showers and thunderstorms into Friday. Temperatures are forecast to warm into the low 20's by the weekend, assuming the front clears the city.
Below Normal Snowfall
A good friend of mine asked me yesterday how much snow we had this past winter. My reply was none, but I really did not have an accurate figure in mind. He guessed 125cm for the season and he was not far off. I scanned the records and all I could come up with was 128cm a paltry 52 inches or so. The normal for Montreal is nearly double that at 217.5cm. The worst month of this bizarre winter was April with officially only 0.4cm of snow. The most snow fell in January with 57.6cm. I used my snow blower on the driveway maybe three times, not even one tank of gas on the machine. As far as snowstorms go, really, not too many. I found only two days with 15cm (6 inches) or more of snow, December 5 and January 12th, tied at 16cm each. Most of the early storms were more ice than snow events, and with temperatures soaring into the high 20's in March, winter 2011/2012 was a non event.

Warmer week ahead
High pressure over the weekend provided us with a sunny and dry couple of days. Unfortunately it was cold and windy as well. Gusty northwest winds help to make it feel much colder than the plus 8 or 9C highs Montreal had. Frost warnings were posted all weekend but here on L'Ile Perrot those same winds managed to keep away the frost. It was chilly with lows below freezing the last three mornings including -1C this am. The only frost I managed to see was a little on the car this morning. It will warm quickly today under sunny skies and light winds to around 15C. The balance of the week will be somewhat unsettled but mild. We are looking at showers on Tuesday as a system passes well south of the border. Wednesday we may see some partial clearing before another round of showers and even some thunderstorms Thursday and Friday. It will be warm however with temperatures rising to near 20C by mid week.

Frost Warning
| Overnight lows in degrees Fahrenheit for the border region. It will be cold with widespread frost in Quebec, Ontario and New England tonight. (NWS Burlington) |
Cold high pressure is settling in behind a departing cold front and low pressure this morning. The storm system that gave the region rain last night is now strengthening over southern Maine. It is forecast to move across Atlantic Canada with heavy rain and even some snow across the lower St. Lawrence and Gaspe area.
Meanwhile in its wake much colder air is settling across southern Quebec and Ontario this morning. Temperatures have fallen with strong northwest winds this morning into the -1 to plus 3C range. With the wind it feels even colder making it rather raw and chilly for late April. Toss in a few snowflakes and we have an unseasonable Friday ahead of us. Things will clear out for the weekend with sunny and dry weather expected but it will be cold. Environment Canada has posted frost warnings for southwestern Quebec and the National Weather Service has them in effect for the St. Lawrence and Champlain Valley's of New York and Vermont where the growing season has started early. Overnight lows will drop to the -5 to -8C range, well below normal, and likely providing a heavy frost if not a solid freeze. If you have anything growing, cover them up to save them. High temperatures across the area under sunny skies will be cold, no warmer than 10C on both Saturday and Sunday.

Finally a little sun
| Over 20cm of snow fell in Orangeville, Ontario on Monday. CBC News |
It has been a dismal weather week with lots of clouds, showers, wet snow and even some small hail since Monday's strong storm moved across the region. That system is now well north of us over Hudson Bay giving blizzard conditions to far northern Quebec. Most of us had more rain from that storm in 24 hours than we had seen in the entire month of April. I measured around 42mm here on L'Ile Perrot with closer to 30mm at the airport. Just a trace of snow fell in Montreal, but as much as 10cm fell down the 401 in the Thousand Islands and over 20cm west of Toronto in Orangeville. The snow created a bunch of accidents closing the 401 for a spell as well as cancelling school buses for thousands of students in Ontario. Despite everybody being shocked, a glance at the record books shows it was not that unusual with many historic mid and late April snowstorms over the years in Ontario and Quebec.
Today we start of with some sunshine and chilly temperatures with a light frost here on L'Ile Perrot at 0C. We will have some brief sunshine however clouds are on the increase once again as low pressure in the Ohio Valley moves northeast across New York. Temperatures may warm to around 10C or so today. Look for rain to develop later today with winds increasing to 20-40km/h. Rain overnight may mix with a few flurries before ending by morning. Another 15-20mm of rain is likely as we continue to balance the precipitation books for the month. Slow clearing arrives Friday followed by a sunny but chilly weekend with cold lows well below freezing. If you planted early be prepared to protect that vegetation this weekend as widespread frost and freezing temperatures are likely across the entire area including metro regions. It will slowly warm up next week as we welcome May and hopefully real spring.

Nor'Easter continues
** The weather has resulted in school bus cancellations across Stormont, Dundas and Glengarry Counties in Ontario as well as Cornwall and some in Leeds & Grenville.
Heavy Rain Warning for Montreal today.
High wind advisory for the St. Lawrence Valley
Snow in Ottawa.
It will be a stormy day today across western Quebec, Eastern Ontario and New England as strong low pressure lifts north from the Jersey Shore into the central Adirondacks later today. Overnight Montreal had a mix of rain and very wet snow with a slushy coating on my car this morning that is rapidly being washed away. The rain was heavy at times with close to 30mm or over 1 inch here on L'Ile Perrot since 10pm. Temperatures were as low as 1C and are at a chilly plus 2C (36F) now. Winds are strong out of the northeast at 50km/h with a peak gust overnight to 71km/h at Trudeau Airport and they will continue to gust to 70km/h today.
While enough warm air is in place in Montreal for rain you do not have to go very far west to have snow. Along and west of the 416 corridor in Ontario including Ottawa a heavy wet snow has visibility down to 1km at times. From Prescott north through Kemptville to Ottawa and west a good 2-5cm of snow has fallen and will continue to fall today while mixing with rain at times. Roads are snow covered in places and travel is slow. It is raining in Toronto but south of the GTA in the Niagara Region and western New York heavy snow is developing and will accumulate 5 to 10 inches (up to 25cm) locally. The heavy nature of the snow will bring down trees and power lines. There is even a good chance of some thunder with the snow at times.
As the low moves northward a pronounced dry slot is working its way into the Champlain Valley and north towards Montreal. As a result we may see a break in the precipitation in Montreal later this morning. Look for a generally wet and windy day across the region with highs near 10C for Montreal south and east and between 2 and 5C for points north and west.

Heavy rain & snow
| NOAA image this afternoon of the developing storm over the Atlantic Ocean near Cape Hatteras. Heavy rain and snow will spread north and west. |
The same storm is forecast to dump heavy rain up and down the eastern seaboard with coastal flooding all the way north into Atlantic Canada. Southern New Brunswick could see 100mm (4 inches) of rain with freezing rain across the north. In central Quebec heavy snow is forecast. This is a developing storm with still some uncertainty so check back later this evening.

Wet weekend update
It is chilly in Montreal this morning with some showers draped along the Quebec/Vermont border. A warm front will try to push north of Montreal today, until it does we will have northeast winds and chilly highs of around 9C. Once the front moves north of the city we should see a brief shot of warm air on Saturday that could push temperatures up to 18C. It will be short lived as a cold front and low pressure area will give rain late Saturday into Sunday. The big weather story then begins late Sunday night and lasts well into next week. A rather large coastal storm will develop near the Delmarva and move north and begin to affect New England, Quebec and Ontario. Lots of precipitation, as much as 50mm or more along with strong winds and cool temperatures are expected to start the work week. There is even a growing possibility of wet snow for some of us. The exact track and intensity of the storm is yet to be determined, so there are lots of details to sort out. Look for cloudy, damp and cool weather until at least Wednesday of next week.

Enjoy today - a wet weekend ahead
It will be another spectacular spring day in Montreal with a warmer southwest wind developing and temperatures rising rapidly to around 20C (68F) this afternoon. That will be quite a bit warmer than Wednesday when the mercury reached 11C in the city and around 12 to 15C off island. That high pressure will slowly drift off the Atlantic coast today allowing low pressure and a stationary front to establish itself over the area for the upcoming weekend. The first system in Michigan today will move along the international border on Friday with a period of showers and much cooler weather here in Montreal. By Saturday a cold front will approach the area with widespread rain expected. We may see some brief partial sunshine on Sunday before a much larger storm develops off the east coast near Virginia and moves north. This system will be the first coastal storm in quite some time to affect the region. Gusty winds, chilly temperatures and widespread rainfall, possibly up to 50mm (2 inches) may fall late Sunday into Monday. There is even a risk of some wet snow for places like the Adirondacks in northern New York. The track and details are still a little up in the air, but we do need the rain desperately in the area, so it would be welcome. In any event today will be near perfect - so get out and enjoy.

Frosty morning
It is hard to believe we are sitting below freezing in Montreal, Ottawa and Toronto this morning after reaching nearly 30C (86F) on Monday. But here we are back to the gloves with a touch of frost on the ground and certainly on your front windshield. High pressure settled into southern Quebec and Ontario overnight with calm winds and cold temperatures. A widespread frost and in some cases a freeze has occurred across Michigan and Ontario south into Ohio and New York as well as most of Quebec. It could be worse, snow is still on the ground across northwest Ontario with as much as 40cm in some locations. Another round of snow, likely 10cm or so is forecast later today for that same area.
Our weather will be controlled by high pressure into Friday with warming temperatures and just some high cirrus clouds. By Friday the weather will become increasingly stormy into the weekend and early next week. A complicated collection of systems will begin to affect southern Quebec, the most important being a potent low pressure area moving from the Gulf of Mexico up the eastern seaboard. This storm will have the potential to produce heavy rain with up to 50mm (2 inches) possible along the track. It is much needed rain so it will be welcomed to help lower the recent fire threat. It will however mean a wash out for the weekend at this time. Winds will be gusty and it will be chilly. It may even be cold enough for some wet snow in some elevated location and north of Montreal, but we will look at that a little closer as we move towards the weekend. In the meantime enjoy the sunshine, it will warm to 12C today and up to 18C on Thursday.

Summer vs Winter
UPDATE 12:30PM: I have two more record highs to add to the list, Kemptville hit 28.3C yesterday breaking the old record of 27.6C set in 2002, and Brockville was 28.4C, the old record from 1973 was 24.4C. Today, just 24 hours later, most places are in the cold plus 9 to 11C (48-52F) range with a strong west wind. From shorts to gloves!
SUMMER
I really did not think we had a chance, but there it is, a new official record high for April 16 of 28.9C (85F) at Trudeau Airport, squeaking past the old record of 28.7C set in 2002. By my count that makes 6 record highs already this year for Montreal. There were dozens of other records smashed including 31.4C (88F) at St Anicet, 29.9C (86F) at St Anne's on the West Island and 29C (85F) at Lennoxville. I was at 31C here on L'Ile Perrot, and we had around 10mm of rain with the front last night. Temperatures all over the region nudged into the high 20's and low 30's, normal for mid July. Burlington, Vermont was still at 27C (80F) last night at 11pm! A strong cold front has chilled things way down this morning as we sit at 12C (54F) with a gusty west wind up to 50km/h. Temperatures will not move much today staying in the 13 to 15C range, but with plenty of sunshine. Winds will abate this evening and temperatures will drop to near freezing. As a matter of fact freeze warnings and watches are in effect for a large area of western New York and Ohio where the growing season is well underway.
That same cold front was the focus for strong southwest winds ahead of it on Monday. Winds gusted to over 95km/h across most of southern Ontario including 96km/h at London and Hamilton with 70 and 80km/h gusts in the GTA. The winds toppled trees, power lines and signs knocking out power to thousands of homes and businesses. It even knocked over a semi-truck on Highway 400 north of Toronto. The front also produced some scattered thunderstorms, but only showers rolled through Montreal in the middle part of the evening.
WINTER
The parent low pressure area of that cold front meanwhile was producing heavy snow and freezing rain across northern Minnesota into northwest Ontario including Thunder Bay where 3 hours of freezing rain was reported. In Timmins over 14 hours of ice snarled traffic and cut power. Atikokan had snow and lots of it with 27cm, while Kapuskasing recorded 32cm. The OPP had to close the Trans Canada Highway near Wawa because of severe winter weather.

Titanic 100 Year Anniversary
| The ghostly image of the Titanic 2.5 miles below the frigid waters of the North Atlantic nearly 400 miles off the Nova Scotia coast. |
The distress call from RMS TITANIC at 11:55 PM, April 14, 1912. (Position Lat. 41.46 N Long. 50.14 W)
As I write this entry it is almost the exact moment 100 years ago that the SS Titanic out of Southampton, England hit an iceberg that would eventually lead to her sinking around 2:40am on the 15th of April, 1912. Sadly, as we all know 1500 souls were lost on that terrible night. By all accounts the voyage to that point was uneventful in the weather department. The waters of the Atlantic had been calm with sunny, mild days and starlit nights. The same held true the night of the collision, maybe a little too calm. The presence or lack there of any weather, or moon (new moon) for that mater would mean that any ice would have been difficult to spot. In addition to the calm, mirror like seas, it was a very cold night. The Titanic had sailed through a cold front earlier in the day that had left her in air temperatures right around the freezing point by 11:40pm. The water was frigid by some estimates almost as cold as -2C (28F). Sea water can reach temperatures below 0C without freezing due to the salt content. In water temperatures such as these survival would have been nearly impossible with death in minutes.
By comparison that night, Montreal was plus 5C (41F) on the 14th and dropped below freezing overnight. In St. John's, Newfoundland, the closest major centre to the Titanic disaster, cold temperatures prevailed behind the cold front with highs of plus 3C (38F) on the 14th and plus 4C (39F) on the 15th. In Halifax where many of the dead from Titanic are buried, and rescue and recovery efforts were launched, it was a mild 10C (50F) on the 14th. Temperatures in Halifax dropped quickly behind the same cold front that the Titanic had encountered, down to -4.4C (25F) by the morning of the 15th showing how cold the air was in the region. New York City where the Titanic was expected was also chilly and clear on the 15th.

Weekend Update
After the clouds, showers and hail of this past week, we have a spectacular Friday and Saturday on tap for southern Quebec and eastern Ontario. Sunshine today will allow temperatures to rebound nicely from near the freezing point this morning up towards 16C (61F) by this afternoon. Nothing but sunshine today with fairly light westerly winds. Winds will increase overnight and Saturday as a frontal system approaches from the southwest. Overnight lows will be milder than this morning, remaining around 5C (41F). On Saturday look for a breezy day with partial sunshine and highs near 16C once again. That frontal boundary will move into the region on Sunday with a few showers and perhaps a thunderstorm. Winds will be gusty up to 40km/h and highs will be near 17C (63F). On Monday a warm front will lift north of the region putting most of Ontario, New England and extreme southern Quebec in some very warm and even humid air. Highs will soar to around 23C (73F) in Montreal but as warm as 26C (79F) in parts of the St. Lawrence Valley. A cold front late in the day may trigger some showers and perhaps a rumble of thunder.
Sunday, April 15 in the wee hours of the morning, we mark a somber event, the 100th anniversary of the sinking of the HMS Titanic. The ship went down in under three hours after striking an iceberg. Nearly 1500 souls were lost that terrible night. Tomorrow's blog entry will feature a brief look at the weather that night not only at the crash site but also for comparison along the coast and here in Montreal.

One more showery day
We continue to have an upper level low spinning near Quebec City, the same one that was over the Atlantic Ocean last weekend. It will slowly drift south into northern Vermont today and eventually east back out to sea by Thursday. Here in southern Quebec and across eastern Ontario we are looking at one more day of showers. Yesterday afternoon the radar image resembled a popcorn machine with little kernels of instability bubbling up all over the place in the cool and humid air. We can expect the same today with a few very small sunny breaks early in the day followed by scattered to numerous showers and even some small hail. We did have a little hail in the late afternoon here on L'Ile Perrot yesterday.
This will be the last day of showers with a very slow clearing forecast for Thursday and warm sunshine by Friday. The temperature will be 10C today, followed by lows near 1C tonight. Friday and into the weekend we can expect much warmer highs near 16C.
The big precipitation with this system has been falling across the high peaks of the Green Mountains. The oragraphic lift created by the northwest winds has produced steady and at times heavy snow showers with 19 inches so far at Killington Mountain and 15 inches at Jay Peak. The snow has been a blessing it what was otherwise a poor ski season in Vermont. It has allowed both resorts to open trails and welcome hoards of skiers looking for a final run. This was the biggest snowfall of the season in Killington.
This will be the last day of showers with a very slow clearing forecast for Thursday and warm sunshine by Friday. The temperature will be 10C today, followed by lows near 1C tonight. Friday and into the weekend we can expect much warmer highs near 16C.

Showers or flurries & chilly
![]() |
| Low pressure is moving west into southern Quebec this week with flurries & showers. |
The week starts off chilly with clouds, showers and temperatures in the 8C range for highs and 2 or 3C for lows in eastern Ontario and southwest Quebec. There may even be a few snowflakes across the regions northeast of Montreal and in the mountains of Vermont and New York. Stubborn low pressure that dealt the Maritimes an Easter Sunday snowstorm is retrograding (in weather terms, basically moving the wrong way) west towards northern Maine and eventually northern Vermont or extreme southern Quebec. It will take most of the week for the pattern to resume a more normal flow and sweep the low pressure area back east and out to sea. Until then look for lots of clouds, temperatures below normal, a chilly wind and showers scattered around at any time into at least Wednesday if not Thursday.
