Northern Ontario: Thunderstorm Outlook for Friday, June 25, 2021

Forecast Discussion

Heavy rainfall and isolated embedded thunderstorms courtesy of a moisture-laden system are expected through southern parts of Northeastern Ontario just to the north of Georgian Bay throughout Friday. The main threat will be very heavy rainfall since the system will pump lots of moisture into the region with rainfall totals by the end of Friday potentially exceeding 50mm in some locations. Strong wind gusts and small hail are also possible in the strongest cells.
