Looks like artic front just north of Toronto buy about 40 miles. See how it interacts with band and lake. I do see a explosion of streamers forming over georgian Bay and lake Huron after front passed.
Only thing I can think of is they are counting on what wrfs are showing. Alot of models won't pick up on the snow cause its so shallow in atmosphere after front goes thru.
Becoming very squally in roc. Band from Huron over ontario. Probably won't last long as wind is backing more west now. Eastern lake ontario is about to launch off.
You almost in the worst area of Southern Ontario for lake snow. Its good you can get some bonus snow with a North East wind. You ever get any erie action. Suspect that's rare would have to be a ssw wind
