Northern Ontario: Thunderstorm Outlook for Thursday, September 16, 2021

Forecast Discussion

Scattered thunderstorms are possible during the day on Thursday through parts of Northwestern Ontario along the International border. A few of these storms particularly during the afternoon and evening could reach severe levels with large hail, strong wind gusts and heavy rainfall. An isolated tornado can’t be ruled out either but it’s very questionable. The storm risk will come to an end later in the evening.
