Southern Ontario: Thunderstorm Outlook for Tuesday, July 6, 2021

Forecast Discussion

A few pop-up non-severe thunderstorms are possible along the northern Lake Erie shoreline during the afternoon and early evening on Tuesday. These storms will be extremly isolated so not all locations will see them. Current indicaqtions suggest that any storms that develop will move quite slowly so flash flooding could be an issue with 50+mm of rain in a short timeframe. Other threats include moderate-sized hail and strong wind gusts, but they should remain non-severe aside from the flooding risk. The storm threat will come to an end late in the evening as the storms fizzle out after sunset.
