For tomorrow, keep an umbrella handy across southern Ontario as a low-pressure system tracks through, bringing rain to Toronto and the GTA by mid-morning, though the day will turn milder south of the lake.
What will the temperature feel like tomorrow?
With the live forecast above showing highs near 10°C in Toronto, the damp air and cloud cover will make it feel several degrees cooler, especially in the afternoon when a brisk northeast wind picks up. In Mississauga and Brampton, the “feels like” temperature will hover 2–3 degrees below the actual high, so a wind-resistant jacket is your best bet.
How will conditions vary across the region?
The rain will arrive earliest for Toronto, Mississauga, and Brampton — generally between 8 a.m. and 11 a.m. — before tapering to showers by late afternoon. Areas north of the city, including parts of York Region, may see the rain linger into the evening, while lakefront neighbourhoods benefit from slightly warmer lake breezes.
Will the rain affect my commute in Brampton or Mississauga tomorrow?
Yes, the rain is expected to start around 9 a.m. for Brampton and Mississauga, coinciding with the late-morning commute. Reduced visibility and slick roads may slow travel along highways 410 and 403, so allow extra time.
Is there a chance of thunder or severe weather with tomorrow’s system?
No — this is a classic March rain event, not a thunderstorm. The system lacks the instability needed for lightning. Expect only steady rain with no severe weather warnings currently issued for southern Ontario.
Will we see any sun breaks tomorrow afternoon?
Brief glimpses of blue sky are possible late in the afternoon across Toronto once the main band of rain pushes east, but cloud cover will persist into the evening for most of the GTA. Overnight clearing is more likely.
