Create Account Environment Canada meteorologist Julien Pellerin says scorching temperatures over the eastern part of the continent are causing below-normal temperatures in other regions. On Saturday, the weather agency warned that areas in British Columbia could face heavy showers, and over some of the highway summits, the possibility of wet snow. Pellerin says the Prairies are also experiencing colder-than-normal temperatures and severe thunderstorms that can be linked to the extreme heat elsewhere. He says the dangerous heat levels span from southwestern Ontario towards North Bay, Sudbury and Timmins, while in Quebec the highest temperatures are expected from Montreal to Shawinigan and north up to Abitibi. Pellerin says he expects Ontario and Quebec to hit their peak daytime highs on Monday and Tuesday with temperatures rising above 30 C, and the humidex making it feel more like 40 to 45 degrees, depending on the region.
