FORECAST DISCUSSION

Widespread thunderstorm activity is expected across Southern Ontario during the afternoon on Tuesday. Some of these storms may become severe with all threat types possible (hail, wind, flooding and tornado). Confidence is low in the exact severity and location so we’re sticking with an isolated risk for now. An upgrade to a ‘slight’ or even ‘strong’ risk isn’t out of the question once we get closer to Tuesday. An updated forecast will be issued sometime on Monday.
