The calm after the storm in Montreal

Heavy snow fell across the extreme southwestern corner of the province on Saturday, with 25 to 30cm accumulating from Ile Perrot (shown above) towards the Ontario border. At my home on Ile Perrot, 41cm has fallen since Tuesday. To date just over 230cm of snow has fallen for the season at Trudeau Airport. (Valley Weather Photo)

The snowstorm is winding down across southwestern Quebec Saturday evening. I always knew the island of Montreal would be on the edge of the heaviest precipitation associated with this storm, but I never anticipated such a wide range of accumulations across such a small geographical area. The heaviest snow fell along and south of the St. Lawrence River from Ile Perrot to the Ontario border.

Across the extreme southwest corner of the province, accumulations of snow were significant, with 30cm reported at both Valleyfield and Vaudreuil-Dorion. Here on Ile Perrot, I measured 25cm at my home, while just 24 kilometres northeast at Trudeau Airport, only 14cm fell. Amounts were even less further north and east of the city, with 8cm reported in Laval and 7cm in Drummondville. Only flurries were observed in Quebec City.

Roads were snow covered and travel was quite difficult this morning heading southwest towards the Ontario border along both highways 20 and 40. Lighter snow this afternoon, along with warmer temperatures allowed for road conditions to improve quickly.

Low pressure continues to move away from New England this evening, with light snow ending by midnight. Temperatures will drop down to -5C (23F) under cloudy skies. Sunday will see a return of above freezing temperatures, with some clearing expected by late afternoon. There may be an isolated snowflake or two. The high temperature should reach plus 3C (38F) in Montreal, so expect some melting. Monday will be partly sunny and continuing mild, up to 4C (39F).
