Sunday
Areas: Southern Manitoba into northwestern Ontario
Timing: Sunday afternoon and evening
Weather: We’ll see some heat and instability pump into northwestern Ontario and southern Manitoba on Sunday as the ridge of high pressure builds toward the east.
A warm front lifting north will usher in enhanced moisture and instability by the afternoon hours, as well as serving as a focus for thunderstorm development and organization across northwestern Ontario.
The main hazards will be strong wind gusts, large hail, and heavy rainfall given the ample moisture present over the region.
Sunday overnight into Monday
Areas: Southern Manitoba into northwestern Ontario
Timing: Sunday overnight
Weather: The risk for thunderstorms will shift east through Sunday night into Monday morning as a cold front pushes across the region.
These overnight storms shouldn’t pack quite the punch as their daytime counterparts, but the affected areas could still see small hail, heavy rainfall, and gusty winds.
