Snowstorm Forecast Map and Quick Update

February 25, 2013; 4:48 PM ET

Monday late afternoon update

--Latest computer models have trended a little farther south/colder for this storm, which makes sense based on actual observations from earlier today.

--The snow map issued below goes through Wednesday, but there will be additional snowfall into Thursday morning across eastern Ontario and southern Quebec, so that places such as Ottawa and Montreal will likely end up with at least 15 cm.

--Snow will also shift into southern New Brunswick and Nova Scotia on Thursday with some accumulation likely, though not as much as Ontario/Quebec.

--The Tuesday evening commute home should be OK in terms of weather from the GTA on northeast. However, much different story for this region Wednesday morning, so allow a good deal of extra time to get to work on Wednesday.

--The latest ECMWF model does predict an area of 30 cm plus for this storm from Hamilton to Kitchener to Toronto to Newmarket and Peterborough, Ontario.

Map adjustments will of course be made throughout the storm.

This should set us up for a great week and weekend of skiing/snowboarding/snowmobiling across large portions of Ontario and southern Quebec as it will stay cold with flurries and snow showers later in the week.

Earlier post from Monday....

It's a busy day today doing the forecaster graphics schedule for Here is our latest thinking for the snowstorm (based on 06Z models and current data) that comes up into Ontario and Quebec Tuesday evening through Wednesday. I will have further updates later today/evening as more information becomes available.

It does look like the mix line gets up to near Sarnia, London to Hamilton line with all or mostly snow to the north of that line.

By the way, the latest 12z NAM model is a little farther south and colder than the previous run.
