A cold front approaching through the afternoon hours will trigger another round of thunderstorms from southwestern Ontario through the Niagara Peninsula.
Several of the storms around Niagara could turn severe, posing a risk for heavy rainfall, strong wind gusts, and small hail.
Rainfall warnings remain in effect through Saturday as an additional 10-30 mm of rain is on the way. Locally higher totals may fall in thunderstorms. The combination of heavy rainfall and saturated ground may increase the flood risk in some areas.
Things will change in a hurry behind this cold front. Temperatures will tumble back into the single digits by Sunday, with the chance for a wintry mix spreading across southern Ontario.
