Southern Ontario: Thunderstorm Outlook for Saturday, July 3, 2021

Forecast Discussion

A very small localized zone through Eastern Ontario extending from north of Lake Ontario through Peterborough/Bancroft and up into Pembroke along the Quebec border could see a few pop-up showers and maybe one or two non-severe thunderstorms during the afternoon on Saturday. These storms will quite weak and won’t pose much of a threat besides lightning and heavy rainfall. It will be extremely isolated so not every location within the risk zone will see rain or thunderstorms. The threat will come to an end by midnight.
