Low pressure is moving from Lake Superior across Ontario and into southern Quebec today. In advance of the system cold rain and snow showers have overspread the region this morning. It is very chilly and raw here on L'Ile Perrot with about 1mm of rain since 7am. Current temperatures are 4C (39F) at my home. You don't have to go far north to have snow falling. Transport Quebec traffic cameras from the Laurentian Autoroute as close as St. Jerome show snow accumulating on the roadsides. Some areas of southern Quebec may see as much as 10cm of wet snow today. The system is also expected to produce strong winds later today. Winds will be 40-70km/h with gusts as high as 90km/h along the shores of Lake Ontario. Wind warnings have been posted on both the Canadian and US shores. Temperatures today will do no better than 6C (43F) in Montreal. Tonight the precipitation will continue with a windy and cold overnight low of 5C (41F). Montreal will stay at 5C on Sunday with more showers.
As with the last storm that came across the Great Lakes this past Thursday, some regions will see lake effect snow once again later tonight and on Sunday. On Thursday, 10-15cm of wet snow fell in places like Barrie, and Flesherton, Ontario (photos above & below) with roads snow covered and icy. Snow also fell in Ohio and western New York. As I have already said this week, now is the time to get ready.
