Hot Weather Expected Across Ontario, Quebec, & New Brunswick

Southwestern Quebec

Areas of Southwestern Quebec will also experience warmer temperatures today. The hot weather will linger through Wednesday and Thursday. Daytime temperatures will reach 30 degrees in some areas combined with humidex values in the high thirties.
