A cold front will sweep away the muggy air that fueled a weekend of powerful thunderstorms across Ontario.

Widespread severe thunderstorms swept across portions of Ontario this weekend, resulting in reports of wind damage, large hail, and localized flooding for some areas. The storms knocked out power for tens of thousands of customers throughout Ontario on Sunday. A cold front will bring a welcome change this week. More on what to expect leading up to the long weekend, below.


A cold front sweeping across the Great Lakes will allow drier air to filter over much of Ontario to start the week. Monday will still come in quite warm, but the humidity will decrease through the day.


Much of the region will see cooler, near-seasonal temperatures and less humidity for most of the upcoming week. It’ll feel more like normal summer weather as opposed to the kind of air you feel like you have to swim through to get around.

Daytime highs will come close to seasonal in the Greater Toronto Area, and it won’t feel too bad with the humidity at a more tolerable level.

We should get through the week mostly dry, with no large-scale storm systems moving across the region. The remnants of Hurricane Ida should remain stateside.


We could see warmer weather for the start of the long weekend, but the details are a bit uncertain this far out.

Stay tuned for the latest forecast across Ontario.
