Blustery winds and temperature drop to hit Ontario before snow squalls

Change is on the horizon for southern Ontario as blustery winds and dropping temperatures will transition rain to snow for the second half of the week.

Southern Ontario is taking another plunge into winter this week and into December with several shots of Arctic air, gusty winds and lake-effect snowfall.

That means we will see multiple snow opportunities in the coming days, especially late week.

Before we get there, southern Ontario will be getting a considerable temperature plummet and blustery wind gusts as high as 80+ km/h for some areas on Wednesday, setting the stage for the significant, lake-effect snow squalls on Thursday and Friday.

Impacts include trickier drives with strong winds and possibility of localized power outages.

Widespread, southwesterly winds will blow across much of southern Ontario into Wednesday evening. Sustained winds of 40+ km/h and gusts 60-80+ km/h are expected. The strongest winds will be focused to the shorelines and southwest and parts of the Greater Toronto Area (GTA).

Late Wednesday and into Thursday is when conditions will begin to feel much more winter-like. Showers will transition to a wet mix and snow before winds align to deliver a heavy amount of snow in a multi-day, lake-effect snow event.
