Environment Canada: Extreme heat continuing today in Ontario, Quebec

Eastern Ontario and much of western Quebec are forecast to experience another day of sweltering weather, with the nation’s capital expected to hit a high of 34 C by Wednesday afternoon.

Environment Canada’s heat warnings say daytime highs are expected to hit 43 with the humidex. And while the daytime hours are expected to be steamy, there may be some relief during the overnights.

The agency says the low overnight on Wednesday is expected to be 23 C.

However, any benefit from the roughly 10-degree difference could very well be lost when factoring in humidex values.

Deteriorating air quality can also be a factor on these hot days, so don’t forget to check in with loved ones to ensure they are cool and coping.
