If you are one of the few who had hoped to see snowflakes fly just one more time in Montreal, then you are in luck. Otherwise, turn away now from this forecast. After what has been a fairly warm month, we are looking at the potential for accumulating snow this Wednesday.
April 15 UPDATE: The rain has started across southern Quebec and will persist into Friday. I have already measured 3.5mm of rain on Ile Perrot since 7am, easily eclipsing the monthly total up until this morning of 0.4mm.
High pressure will dominate the weather picture for the upcoming week across southern Quebec. Stubborn low pressure over Nova Scotia will ensure a damp, cool week for Atlantic Canada and portions of eastern Quebec, while allowing high pressure to remain stationary over our region. Some showe…
UPDATE: April 1 - 8:15AM: I guess Mother Nature has pulled an April Fools joke on us, as there is no snow on the ground in Montreal this morning. The low pressure system in question has moved further east along the Atlantic coast. The storm is also moving along at a faster clip. Both these f…
Strong west winds of 50 to 80km/h are forecast for Montreal Sunday night into Monday, along with rain changing to snow showers after midnight.
3:45 PM Update: Heavy rain warning in effect for metro Montreal. Expect 25 to 45mm of rain overnight into Friday. There is also a risk of thunderstorms.
Rainfall Warning in effect for southern Quebec for Friday.
I hope I don't regret this, but it looks like a very quiet end to the winter season in Montreal, and perhaps the entire month of March. I am not saying that it is out of the realm of possibility that we receive a sneaky snowfall or two between now and the end of April, but for now no major s…
Our preview to spring is just about over in eastern Canada. The high in Montreal on Wednesday was 9C (49F), just shy of the record high for the date. We have a much better chance of reaching the record today, 11.2C (52F) set back in 2012. The forecast is for a high of 10C (50F), however ther…
With thoughts from veteran CJAD Traffic Reporter Rick Leckner
Today is the 50th Anniversary of the Montreal Blizzard of 71. The 1971 storm continues to draw numerous comments to my posts through the years. I have shared a few below.
Snow Squall Watch cancelled for southern Quebec
Could we be looking at the end of winter already? A very mild period of weather is forecast across southern Quebec over the next week and perhaps even longer. Temperatures will be at or slightly above the freezing point as we head towards the start of meteorological spring on March 1st. Whil…
***ALL weather warnings for metro Montreal have expired as of 11:30AM. Close to 17cm of snow has fallen, with only flurries expected for the balance of the day.
***ALL weather warnings for metro Montreal have expired.
Two major storm systems are set to impact Montreal and southern Quebec over the next week. This is all part of the series of winter storms that have been moving around the periphery of a cold dome of arctic air that has descended upon the central portion of the continent. The cold has sent s…
A significant record-breaking cold snap is underway across most of western Canada. Temperatures have dropped into the minus 20s and 30s for highs and down as cold at the minus 40s for lows over the past week. The arctic air has been in place since last weekend and is now starting to spread e…
Regardless of what the groundhog had to say last week, winter is here to stay in southern Quebec for awhile. While Montreal will escape the worst of the current cold snap and the heaviest now over the next week, the weather will still feel like mid-winter.
Update 8:45 AM: All weather warnings have expired for metro Montreal, with only light snow forecast for the remainder of Wednesday. Officially at Trudeau Airport, close to 20cm of snow fell, however many locations around the region reported more. I measured 26cm on Ile Perrot for the 24 hour…
Special Weather Statement in effect for southern Quebec for 10-20cm of snow Tuesday.
The coldest temperatures so far this winter are anticipated tonight through Sunday morning across southern Quebec, Ontario and New England. Montreal along with parts of eastern Ontario received a surprise 5 to 10cm of snow Tuesday evening in a little less than 6 hours. The snow was part of a…
I know I promised a quiet week, but weather happens. Weak low pressure was expected to remain well south of Montreal this week, however the path has brought it a little closer to the region. As I write, an area of steady snow is moving northeast along Highway 401 from Toronto towards the Ont…
A weak area of low pressure accompanied by an arctic frontal boundary delivered 5 to 10cm of fluffy light snow to southern Quebec over the last 24 hours. The snow caused the usual rash of accidents on area highways. A few more flurries or snow showers are likely Friday before drier air moves…
Snowfall Warning in effect for Montreal.
Snowfall Warning in effect for Montreal, Ottawa and Cornwall
The weather remains rather quiet and dismal across southern Quebec on Wednesday, with just a couple of weak systems impacting the region. The result has been plenty of cloud cover, some light precipitation at times in the form of drizzle or flurries, and little range in temperature. Temperat…
This is a follow-up to the story I wrote back in January 2017. If I seem a little nostalgic at times for winter during that decade, I am. While mild winters are certainly welcome by most, I prefer more traditional winter weather, at least in December and January. The extreme changes in tempe…
Strong high pressure over our region is being blocked from any eastward movement by an upper level low northeast of Atlantic Canada. This is forcing all the weather systems to slow to a crawl, and pushing any storms well south of our region across the southern US. So what you see is what you…
10:30 Update, Saturday, January 2: The snowfall warning is set to expire shortly for metro Montreal after 11 to 15cm of snow fell overnight. Only flurries are expected for the balance of the day...SB
Precipitation has come to an end in Montreal, with temperatures hovering around the freezing point early Thursday morning. It is just cold enough outside for a thin layer of ice on everything, as I found out the hard way leaving the house this morning. The clipper system is now well northeas…
A relatively weak weather system, an Alberta Clipper, will cross the Great Lakes and move just north of Montreal late tonight. Accompanying the system will be an area of light snow and perhaps some mixed precipitation. The low will move northeast of Montreal on Thursday, leaving behind clea…
Heavy rainfall warning in effect for southern Quebec.
Winter is here, officially arriving on Monday morning at 5:02. The good news is that the days will now slowly get longer. To celebrate winters arrival, we have a little light snow falling early Tuesday morning, but it remains very mild, near the freezing point in Montreal. December has certa…
The massive Nor'Easter that dumped record amounts of snow from Pennsylvania to New England is slowly moving towards Nova Scotia on Thursday afternoon. The storm put down a general 30-60cm (12-24 inches) of snow from the central Appalachians into New England. The snow was accompanied by 50 to…
In a scenario all too common this year, another snowstorm is missing southern Quebec, but not by much. A massive Nor'Easter is currently strengthening off the Carolina coast, poised to dump 30-60cm (1-2 feet) of wind-driven snow from Virginia to Nova Scotia. Snow has already started falling …
4PM Update: Temperatures have quickly risen above the freezing point in Montreal and locations south and west of the city, and the threat for freezing rain has now diminished. The warnings have been cancelled for Montreal. Showers will persist this evening and overnight with perhaps some sli…
Winter is desperately trying to establish a foothold in southern Quebec. But with no real cold air in place, it has been difficult at best. The little snow that has fallen to date, including the 4 to 5cm of snow that fell on Wednesday in Montreal, melts away very quickly. Even milder air is …
A poorly timed burst of snow Wednesday morning has turned the commute in Montreal into carnage on the highways. Traffic is crawling in many areas due to the combination of light snow and black ice. Traffic was moving way too fast for the conditions earlier this morning. I witnessed a Hummer …
It is yet another dreary morning in Montreal, with a light cold rain falling. The day will shape up cloudy, with scattered showers and flurries and temperatures fairly steady near 2 or 3C. The big weather news is the potential for a snowstorm this weekend. But before you get too angry or exc…
Strong low pressure is forecast to move from the southern Appalachians towards the Great Lakes on Monday. The strengthening storm will take a very unusual path towards western New York and across Lake Ontario before drifting west across central Ontario and eventually northeast towards James …
A warm front lifting northward towards the St. Lawrence Valley Wednesday morning, has spread an area of light to moderate snow across the region. The snow started in Montreal just before dawn, and has accumulated a couple of centimetres so far.
The first snowfall of the season brought a few surprises along with it. The storm underperformed in southern Quebec but dumped a record-breaking 19cm of snow at Pearson Airport in Toronto. The snow spread across Ontario Sunday, arriving in southern Quebec by 4pm. The snow changed to rain in …
Special Weather Statement for Montreal for 5-10cm of snow Sunday evening.
Strong low pressure moved across the Great Lakes on Sunday bringing powerful winds of up to 141km/h in southern Ontario and 101km/h in Quebec. There were at least 15 reports of winds in excess of 100km/h (60 mph) in Ontario alone, including 100km/h at Toronto's Pearson Airport, 131km/h at Po…
Wind Warning posted for the Richelieu Valley
Colder weather has returned to southern Quebec after our remarkable stretch of warm weather. Conditions were similar to late summer then mid-November. By the numbers it was very impressive. There were dozens upon dozens of new record highs established from central Ontario to Atlantic Canada.…
The wind in the wires made a tattle-tale sound - And a wave broke over the railing - And every man knew, as the captain did too, T'was the witch of November come stealin'.
What a spectacular weekend it was across southern Quebec and Ontario. The weather was more like early September than mid-November. Numerous record highs were established from Ontario to Atlantic Canada. Here in Montreal the high both Saturday and Sunday was just shy of the 20C (68F) mark alt…
UPDATE: Monday, November 2 - 10:45AM: Light snow is falling this morning south of Montreal towards the US border and across the Eastern Townships. Several centimteres are likely. The snow will taper off this afternoon, but start up again this evening. The snow should come to an end early Tue…
Wild weather continues across portions of North America, with a frigid push of Arctic air all the way down to New Mexico and Texas. Meanwhile here in southern Quebec, the first snowfall of season occurred on Monday, with several centimetres falling north of Montreal in the Laurentians. In th…
