Toronto is heading into a stormy stretch of midsummer weather, with forecasters warning of rain, thunderstorms and gusty winds on Tuesday before conditions gradually improve later in the week.
The forecast is calling for a warm, moisture‑laden air mass to move across southern Ontario overnight Monday into Tuesday, setting the stage for periods of rain and the potential for thunderstorms — some of which could be heavy at times.
Precipitation totals will vary depending on location, but Toronto could see 5-10 mm of rain through Tuesday evening, with upwards of 15 mm in some areas. Showers will develop through the morning with embedded thunderstorms possible from late morning into the afternoon.
Forecasters say rainfall could be locally heavy, and brief downpours may reduce visibility during the commute. Winds will pick up from the southwest, adding to the unsettled feel. Temperatures will reach the mid‑20s, though humidity will make it feel warmer.
Wednesday brings a mix of clouds and scattered showers, especially early in the day. A few rumbles of thunder can’t be ruled out, but the risk is lower than Tuesday. Skies should begin to brighten by afternoon with a high near the mid‑20s.
A more stable air mass settles in Thursday, delivering a warm, pleasant day with sunshine and a high in the mid‑20s. Humidity will be moderate, and winds light — a welcome break after two unsettled days.
Friday looks seasonable and calm in Toronto, with a mix of sun and cloud and temperatures hovering in the low‑ to mid‑20s. A stray shower is possible north of the city, but most areas should stay dry.
