Ottawa and Montreal should pay particularly close attention to the forecast over the coming days, as a major weather event is possible here.
Periods of heavy rain will soak southern Ontario, including the Greater Toronto Area, through the day.
A sharp temperature gradient will exist across the region.Easterly winds off the lake will keep the GTA in the single digits even when it’s near 20°C in Windsor. A brief, sharp temperature increase is possible late Wednesday ahead of the cold front’s arrival.
Readings will quickly drop below freezing for all of southern Ontario behind the cold front, creating slick roads and slippery sidewalks. The freezing rain threat will dissipate across eastern Ontario after the front passes through.
Wind gusts behind the cold front will grow to 40-60 km/h through Thursday, making the day’s chilly conditions feel even colder.
