Southern Ontario: Thunderstorm Outlook for Tuesday, June 29, 2021

Forecast Discussion

Isolated thunderstorms are possible across much of Southern Ontario during the afternoon and evening on Tuesday. The exact strength of these storms is currently unclear although it appears that most should remain non-severe. There is a questionable severe risk through parts of Southwestern Ontario, but there are indications that storm development will be further to the north through Central and Eastern Ontario missing out on the prime environment to the south.
