Southern Ontario: Thunderstorm Outlook for Saturday, August 7, 2021

Forecast Discussion

Isolated pop-up storms are expected throughout the afternoon and evening on Saturday across Southern Ontario. A few of these storms could have the potential to reach severe levels mainly through Eastern and Central Ontario. The main risks will be strong wind gusts, small hail and heavy downpours with the storms moving quite slowly. We don’t expect much of a tornado risk with these storms, but there could be some funnel clouds associated with the storms. We’ll see the storms dissipate right after sunset as the daylight heating that was fueling them disappears.
