Tuesday will bring varying conditions to the region, with single digit temperatures expected in Central Ontario and Humidex values in the 30s in Southwestern Ontario.
Rain and thunderstorms will begin this evening in Central and Eastern Ontario and will continue through the day tomorrow. Nearly all areas will likely see rain and potentially some thunder during the morning hours before clearing.
Rain may be heavy at times, and thunderstorms will be possible at any time due to the warm airmass in place. Some thunderstorms in Central and Eastern Ontario may become severe with strong wind gusts and small hail being the main threats.
Localized flooding will be possible tomorrow, especially for areas that receive multiple rounds of torrential downpours. Ensure you do not drive through flooded roadways.
