Storm Snowfall Forecast Maps for West and East

Jan 16, 2012; 12:54 PM ET

Be sure to follow me on my twitter account for quick updates on the weather pattern and storm updates BrettAWX

This is my initial forecast for the storm system that will impact parts of eastern Canada and the Maritimes from early Tuesday through Wednesday.

Once again, it looks like the storm will track very close to the St. Lawrence River Valley. Ski country north of Montreal should do well in terms of snow. Montreal itself will get a small accumulation of snow before a change to sleet and/or freezing rain.

Ice and sleet could be an issue for many areas as well.

------

The combination of a moist, Pacific air flow and Arctic air pressing in from the north will result in periodic snow across southwestern Canada and into the Pacific Northwest through Tuesday. The map below shows expected snowfall from today through Tuesday.

Computer models are still divided on the Pacific storm for Wed/Wed night/Thursday morning. Some bring a healthy dose of snow to the Lower Mainland and Vancouver Island, BC, before going to rain Thursday afternoon, while other models have the cold being so dominant that the storm track is forced too far south and there is little in the way of precipitation, but plenty of cold.

Will try to iron it out later today.
