FORECAST DISCUSSION

There is the risk of non-severe thunderstorms in Deep Southwestern Ontario extending into regions east of Lake Huron. Thunderstorms are expected to develop over Michigan and may cross into Ontario sometime during the afternoon and early evening on Saturday. These storms should be fairly weak, however, there is a very questionable risk for strong storms toward the Windsor, Sarnia and Chatham regions.

The strongest environment for severe activity is expected to remain south of the border, but it isn’t out of the question that one of these storms sneak across the border. Although the confidence is too low for us to introduce an isolated severe risk.
