Toronto is heading into what’s expected to be its warmest week of the year so far, with daytime highs soaring well above seasonal norms and a stretch of windy, unsettled weather carrying the city through to the end of the workweek.
According to 680 NewsRadio weather specialist Denise Andreacchi, the week begins on a mild, unsettled note as Monday brought scattered morning and early‑afternoon showers.
Toronto was expected to reach a high of 21°C Monday, a significant jump from the seasonal average while overnight will be mostly cloudy with a chance of lingering showers and a low near 10°C.
By the pre-dawn hours into early Tuesday morning, there will be a second wave of showers with the risk of thunderstorms, likely bringing locally heavy downpours. Heavy rain and thunderstorms will continue to impact the Tuesday morning commute. Active weather becomes more isolated through the day on Tuesday, with sunny and dry afternoon breaks.
Between 5 and 15 millimetres of rainfall is possible, with locally higher amounts within storms.
A special weather statement has been issued for Caledon along with Northern York and Northern Durham regions and surrounding areas where total rainfall could hit up to 20 millimetres.
More rain in the forecast midweek
Wednesday remains mild overall. The city will see a mix of sunny breaks and scattered showers, with lighter southwest winds of 10 to 20 km/h. The daytime high is forecast at 18°C, with a warm low of 12°C heading into the night.
Another warm day is expected on Thursday, though showers return in the afternoon and evening with about 5 mm of rain anticipated. Winds will pick up again from the southwest at 20 to 40 km/h, and the high will reach 19°C before dropping to 10°C overnight.
Friday rounds out the workweek with more warmth under a mix of sun and cloud. Winds shift slightly to the west‑southwest at 10 to 20 km/h, and temperatures climb to a high near 20°C, with another mild low of 10°C heading into the weekend.
While the warmth holds through Saturday, Andreacchi notes that cooler, more seasonal conditions are expected to return next week.
