Storm # 1 tonight will bring a messy mix tonight of snow to ice pellets to freezing rain to rain back to snow tomorrow. That sounds very familiar, doesn't it.
Storm # 2 is a weak clipper that will give us just a couple cms or so of snow Monday evening.
Storm # 3 is looking to be a bigger deal Tuesday night into Wednesday as system passes just south of the Great Lakes, giving us mostly frozen precipitation. Preliminary snowday call for Wednesday.
After Wednesday's system an Arctic high settles in giving clear and cold conditions with overnight lows potentially getting into the -20s C (overnight low Friday morning shown).

The forecast track is slowly narrowing down to one that has the storm center pass over the lower Great Lakes on a NE course, passing just south of Ottawa. If this holds, snow will begin late afternoon Wednesday. By early morning Thursday, there will likely be a change to freezing rain to rain. Up to 15-20 cms could accumulate before the change to rain. By late Thursday, there will be a change back to snow.

Mentioned a couple days ago on my Twitter feed that model output for next week Tuesday/Wednesday had a similar setup and storm as this week. The storm is still there on the models in one form or another. Look for firming of track and precip in the next couple days.
