If you spend most of the year longing for warm weather, you may be getting a bit more than you bargained for this weekend.

Weather experts are predicting that “dangerous” hot and humid conditions will attack southern Ontario Friday and Saturday, with temperatures into the 40s with the humidex.

“Humidity is really going to be unusually high.” Brett Anderson, senior meteorologist with AccuWeather told Yahoo Canada. “Factoring in the humidity, around Toronto at least, it’s going to feel more like 38 C both days with a high humidity.”

Anderson identified that areas around Windsor will likely experience the highest humidity in the region on Saturday.

“Combination of high heat, humidity, not great air quality tells me if you don’t have to be outside don’t go outside, especially during the afternoon hours,” Anderson said.

This extreme heat will come after a series of rain events and possible thunderstorms from Michigan into southern Ontario, particularly north and west of Toronto.

“Thunderstorms will cool it down but it makes it that much more humid once the storm moves away,” Anderson said.

More ‘comfortable’ weather on the horizon

There is some relief in sight as we near the end of the weekend. Temperatures on Sunday are expected to be a bit cooler and less muggy throughout the region.

“The good news is that we do have a cold front, which will be coming through...Saturday night,” Anderson said. “By Sunday, temperatures should be back where they should be for this time of year, looking at about 29 or 30 C for a high.”

According to Anderson, next week Ontario will see “comfortable” temperatures that will follow a big weather pattern change. The heat will shift to the western parts of North America with more of a northwesterly air flow across Ontario.

“That means less humid,...not a lot of moisture so rainfall is probably going to be below normal, and temperatures are going to be near or slightly below normal,” Anderson said.
