Forecast Discussion

Isolated non-severe thunderstorms are possible across parts of Northern Ontario stretching from Thunder Bay through Kapuskasing and along the Quebec border during the day on Thursday. These storms will be quite weak and some might not be even strong enough to produce lightning. A few still could produce strong wind gusts, small hail and torrential downpours. The storm threat will come to an end just after midnight.
