Saturday, February 27th 2021, 6:00 pm - Spring-like warmth in Ontario faces some messy wintry interruptions this weekend.
Much of southern Ontario basked in temperatures in the mid-to-upper single digits Saturday, with a gloomy morning giving way to sunnier skies in the afternoon. Another round of showers makes its way into the region Sunday morning, though similarly mild temperatures are also in the cards. Beyond, the glimpse of spring-like weather will disappear Monday as a clipper and cold front will quickly send temperatures plummeting, accompanied by a quick shot of snow and intense wind gusts. A closer look, below.
- Unsettled conditions return to the province Sunday morning
- Temperatures milder once again Sunday, though somewhat delayed
- Cooldown once again early next week, with unsettled conditions, though not excessive
SUNDAY: SPRING-LIKE WARMTH DELAYED BY GLOOMY START
Sunday will have a similar setup as Saturday in the south, except the unsettled conditions will hang on a bit longer. Rain returns in the early morning hours in the southwest, reaches GTA by mid-morning.
It won’t be a washout by any means, but showers will continue much of the day before tapering off through the evening continues tracking east. The east will enjoy a little more sunshine to start the day, as the rain won't track in until the afternoon.
Mild temperatures are in store again due to southerly flow for most people, but an east wind off Lake Ontario means cooler temperatures will prevail for longer for some communities. Once the wind shifts to the southwest late-day, the region can expect a return to warmer conditions once again.
BEYOND: UP-AND-DOWN TEMPERATURES, STRONG WINDS, SOME UNSETTLED CONDITIONS
Monday will see temperatures dip and the return of snow, thanks to a clipper and cold front crossing the region. It will be a quick burst, so accumulations will be minimal. A few cm is possible for eastern Ontario, including Ottawa and the Montreal area, with strong winds.
Flurries will be brief, but heavy for the GTA. Bands of lake-effect snow will develop behind the front southeast of Lake Huron and Georgian Bay.
Winds will be intense in southern Ontario Monday afternoon and evening. Gusts of 70-80 km/h will develop, with 90+ km/h possible along Lake Huron shores and Georgian Bay.
Colder than seasonal temperatures are expected for Tuesday, especially for eastern Ontario. By mid-week, temperatures turn milder once again with fair skies, but late week holds some potential for the return of unsettled conditions, as well as another drop in daytime highs for the first weekend of March.
