Toronto remains under heat warning as humid conditions continue

A heat warning is in effect for the city of Toronto today — again.

In case you hadn’t noticed, it is hot outside.

According to the latest Environment Canada update, temperatures on Wednesday will reach 31 or 32°C, across the region in a hot and humid tropical air mass. Humidex values will reach the upper thirties to near 40 this afternoon.

“Hot and humid air can also bring deteriorating air quality and can result in the Air Quality Health Index to approach the high risk category,” the warning says.

“A cold front accompanied by showers and thunderstorms will move through Southern Ontario tonight, bringing this heat event to an end.”

By Thursday, temperatures will drop about 10°C to 21°C, and this weekend will see mild weather along with plenty of sunshine.
