The Gales of November have disrupted the pattern of warmer weather, and now a cold front sweeps through northern Ontario, driving a surge of cold air directly across the Great Lakes—cold enough to trigger a lake-effect snow event. This marks a defining moment in the transition from autumn to winter, with highs struggling to reach the low single digits Sunday and Monday, wind chills making it feel even colder, and the very real possibility of accumulating snow in the coming workweek.
Periods of rain and drizzle are expected to end Friday afternoon, with temperatures reaching 8°C as a cold front continues swinging through the region in the morning. Gusty west winds turn northwest through the day with gusts occasionally pushing 20km/h through the afternoon. Cooler air arrives later in the night as skies partially clear, with temperatures dropping to near -5°C overnight.
Saturday will be partly cloudy, with temperatures reaching only 2°C, as high pressure builds over the Great Lakes this weekend, signalling the start of a notable cooldown that will persist into early next week.
Sunday brings mostly cloudy skies, with lake-effect snow showers developing as temperatures reach only 1°C. The lake-effect snow showers should remain over Michigan with northerly winds, but locations near the airport have some risk for accumulation.
