Isolated Severe Thunderstorm Risk: Overnight, Morning, Afternoon, and Evening (Wed, Jun 1, 2022)

Isolated severe thunderstorms are possible this Wednesday. By “Isolated” we mean that many areas could end up seeing no storms at all. However, even though the storms should remain isolated, many in our community will end up seeing storm activity as there could be quite a few of them, several rounds, and likely in populated areas.

Overnight & Early morning (12am - 8am): Overnight and early morning storms should begin moving east from Lake Huron near Kincardine and tracking towards Georgian Bay, Barrie, etc. We’ll also see storms moving east from Georgian Bay, starting around midnight or so and tracking into Muskoka and parts of eastern Ontario. These overnight and early morning storms have a marginal (low) risk for severe weather but they could bring with them isolated flooding, strong (potentially damaging) wind gusts, hail, and lightning. Tornado activity with these overnight and early morning storms is unlikely but we’ll be watching them, nonetheless as they may end up showing rotation on radar.

Morning: (8am - 11am): The morning storms will have a stronger environment to work with as they track through parts of southwestern and central Ontario, perhaps towards the GTA regions and parts of eastern Ontario. Damaging wind gusts, hail, flooding and lightning are the main risks. Tornado activity with these morning storms is also unlikely. Although, slightly less unlikely than the overnight and early morning storms.

Afternoon & evening: (12pm - 8pm): The afternoon storms are the main concern for tomorrow and we should see these develop around the noon hour or slightly thereafter. Multiple isolated supercells (rotating storms) are possible and at this point, we’re seeing a highlighted risk in southwestern, central, golden horseshoe (GTHA), and parts of eastern Ontario. Large hail, damaging wind gusts, frequent lightning, isolated flooding, and isolated tornadoes will be possible. The dotted “tornado risk” area on the map is specifically showing where the afternoon and evening storms should develop but we’d like to clarify that an isolated tornado outside of this highlight area isn’t entirely out of the question with the morning storms even though their overall tornado potential seems less likely than the afternoon storms.

If we see any rotation on radar, we will do our best to notify all those who have our free app Instant Weather and who subscribe to our premium Text Message Alerts as well as through Facebook, Twitter, etc. Having said that, Facebook notifications are usually very slow so please do not depend on them being timely.

And once again, a huge thank you to all those who share our updates and support our team and community! It makes all of this possible and helps us continue to achieve our goal of raising awareness about tornadoes and severe weather. Thank you!
