Southern Ontario: Thunderstorm Outlook for Tuesday, August 17, 2021

Forecast Discussion

There is the potential for some thunderstorm activity through parts of Southern Ontario on Tuesday. The main focus will be on the morning hours with some non-severe thunderstorms tracking through Southwestern Ontario, GTA and Eastern Ontario. Could also see some pop-up storms later in the day, but it’s questionable and any activity will be super isolated so unlikely most locations will see anything.
