New Storm Snowfall Map

Here is our newly updated snowfall forecast map that includes snowfall from the storm and the lake-effect snow following the storm for the period Thursday night through Saturday.

Keep in mind this does not include snow from yesterday and today from parts of the U.S. Midwest and Plains.

It looks like there will be a general 8-12 cm of snow right in Montreal on the front side of this storm before it changes over to a mix of snow/rain or all rain Friday afternoon. It will go back to snow Friday evening, but most of this accumulation will be on the front side of this storm.

Quebec City may briefly get a mix Friday evening, but the most of the precipitation from this storm should be in the form of snow.

I still think this storm will be 90-100% snow in Ottawa. Areas just north of Ottawa should get the heaviest accumulations. The Laurentian ski areas will be very happy as this will come just in time for the weekend.

Precipitation may start as snow not too far north and northwest of Toronto later this evening before changing over.

Most of the accumulation in and around the Bruce Peninsula area will be on the back side of the storm then with the lake-effect bands Friday evening into Saturday morning. Even though the map shows a maximum of 15-30 cm in the lake-effect snow belts there certainly could be locally higher amounts just inland from the southeastern part of Lake Huron.

Lake-effect snow will wind down Saturday afternoon.

Some computer models continue to show potential for another significant storm midweek next week (late Wed or so) with the potential for a more widespread snow for parts of Ontario and Quebec. More on that later.
