Forecast Discussion

A few localized non-severe thunderstorms may develop during the afternoon and evening on Monday through Southwestern Ontario and into parts of Central Ontario east of Georgian Bay. Any storm activity that does develop will be fairly isolated so not everyone will see them. The main risks with the storms include some strong wind gusts, small hail and heavy downpours. Rain showers with embedded thunderstorms will continue to linger through the overnight and Tuesday morning for some parts of the region.
