FRIDAY: HEAT REMAINS, SEVERE STORM RISK
Relief from the summer-like heat is coming, but not until the weekend, as the return of cooler, seasonal temperatures settles in after the passage of a cold front.
Many cities in southern Quebec will still be sweltering under daytime highs at or above 30°C Friday, with the humidity making it feel more like the mid- to upper-30s.
However, along with the muggy and hot conditions comes a thunderstorm threat in the afternoon, with some to potentially become severe, in parts of central and southern Quebec, including Montreal area. The main threats will be heavy rain, strong winds and small hail.
On the weekend, temperatures will drop off considerably Saturday, as the front eliminates the heat and humidity. Frost is likely Saturday and Sunday nights for parts of Quebec, but not Montreal. Even cooler Sunday across southern Quebec with temperatures more typical of mid/late April.
