Heavy snow blankets southern Quebec - over 25cm in Montreal

The snow is deep here on Ile Perrot, with another 25cm added overnight to the mountains already in place. Our municipality has been exceptional at plowing the roads, but as you can see above, you will need to dig out of your own driveway to get to work or school. (Valley Weather)

The snowfall warning remains in effect through the noon hour for Montreal.

As expected, snow began just prior to the evening commute Wednesday evening in Montreal. The snow became heavy quickly, with 21cm falling before midnight. Strong winds created blowing snow and nearly whiteout travel conditions on area highways, especially south and west of the city. As of 6am Thursday morning, 26cm had fallen in Montreal. Primary roads in the city are in good shape, but mountains of snow remain on side roads and parking lots.

There are delays at Trudeau Airport, call ahead to verify your flight.

Some schools have been closed for the day, especially north of Montreal, but the major boards remain open in the city.

Strong low pressure is moving down the St. Lawrence Valley early Thursday morning, with a secondary low developing near Long Island, New York. This storm will become the dominant system today as it lifts into the Gulf of Maine. We are in a dry slot at the moment, but precipitation should blossom again from the west, with another 5cm of snow expected for Montreal before precipitation tapers off early this afternoon. Gusty west winds will develop by noon, up to 50km/h, causing blowing snow, especially off island.

The snowstorm impacted all of southern and eastern Ontario as well Wednesday, with 13.8cm falling in Toronto and 15.6cm in Ottawa. There were reports of thunder and lightning accompanying the snow in many parts of Ontario, including Kingston. 

Skies will become partly cloudy tonight and Friday before more snow arrives for the weekend. High temperatures today will be around -3C (27F), with overnight lows dropping to -9C (16F).
