What a difference a day makes.
After hot and humid conditions yesterday in southern Ontario, temperatures in the region will be dropping to below seasonal values today. Yesterday, temperatures peaked at 30°C in the city of Toronto, but with the humidex it felt more like 36.
In Ottawa and Montreal temperatures hovered in the mid-twenties, but the warm weather eventually gave way to heavy rain and gusty winds, and lightning.
The Weather Network meterologist Michelle Cassar says that as the cold front moved across the province, conditions cooled behind it. Today won't be nearly as warm as Tuesday, with temperatures dropping into the mid-teens.
The cold temperatures are forecast to continue through Thursday for southern Ontario. Gusty winds and showers are also a possibility as the cold front pushes east.
But the weather will warm up to near normal temperatures on Friday, when it is expected to hit 20°C.
