Cold alerts could soon break in southern Ontario, but predicted to return next week

TORONTO — Cold weather alerts that have gripped most of southern Ontario since Thursday could break by Sunday morning as Environment and Climate Change Canada predicts sunshine on the horizon.

However, the current frigid temperatures Ontarians are experiencing likely aren’t going away any time soon.

Environment Canada meteorologist Mitchell Meredith says cold warnings could return to large swaths of southern Ontario next Saturday as the next wave of cold air comes in.

He says sub-zero temperatures in southern Ontario could stick around until mid-to-late-February – marking a noticeable long stretch of cold temperatures not seen in the region in recent years.

Meredith says Toronto could see a wind chill of -25 overnight before temperatures are forecasted warm to a high of -8 C Sunday.

As cold warnings persist in southern Ontario, Environment Canada has warned of frostbite, which can develop within minutes on exposed skin and cause numbness, a tingling sensation or swelling.
