Southern Ontario: Thunderstorm Outlook for Friday, June 18, 2021

Forecast Discussion

A decaying complex of thunderstorms could track into Southwestern Ontario during the early morning hours on Friday. Current data suggests it will survive overnight as it tracks across Michigan although it’s possible it could fizzle out before reaching the border. Thunderstorms are also possible across Southern Ontario later in the day and a few of these could pose an isolated severe risk. More details to come as the event draws closer.
