Heavy rain and thunderstorms possible Saturday as Toronto heads into a mixed weekend forecast
Forecasters say Saturday will begin with sun and cloud in Toronto, but conditions will deteriorate later in the day as a system moves in from the U.S. Midwest.
Toronto anticipates a series of shifting weather patterns over the upcoming weekend, with a heightened risk of heavy rain and thunderstorms on Saturday. The Toronto area is set to experience a dynamic weather setup, beginning with warm and mostly calm conditions on Friday. By Saturday morning, forecasts suggest a warm high of 26°C under mostly sunny skies.
However, as the day progresses, the influence of a storm system originating from the U.S. Midwest is expected to bring about heavy rain and thunderstorms, particularly in the late afternoon. The system is forecast to bring 10–20 mm of rainfall by the evening, with gusty winds from the east at 15–30 km/h.
Air quality is currently rated at a low risk (AQHI of 3), but the UV Index is predicted to reach 7, advising the public to use sun protection. Sunday may start with unsettled weather, featuring early morning showers or thunderstorms, before clearing up to a sunny day with a high of 23°C. The following Monday is expected to be more stable, with a high of 22°C and a low of 14°C, marking a notable drop in temperature as the cooler, fresher pattern takes hold.
