Heat-busting storms on tap across northern Ontario, eyes on tornado risk
Severe weather makes its way through northern Ontario Tuesday, bringing potent thunderstorms and relief from the heat in its wake
The extreme heat blanketing much of Eastern Canada is helping to fuel a severe thunderstorm threat across northern Ontario for Tuesday.
There is the chance for supercells to develop later in the afternoon, and embedded rotation when they cluster up during the evening hours. Residents are being urged to stay weather-aware as these rotating storms could produce a tornado or two.

Behind the front, temperatures will cool significant for Wednesday, with some areas set to drop by 15°C.
Tuesday
Location: Northwestern Ontario
Timing: Tuesday afternoon and evening
Weather: Severe thunderstorms are forecast to develop Tuesday afternoon and evening, bringing nearly all storm hazards to northwestern Ontario.
Large hail is the initial threat as storms pop up through the day. Weather models are hinting at a slight window for a supercell or two to develop near Ignace.
Heading into the evening, forecasters will also watch any strong, stateside storms that track northeast for these severe hazards. At this point, the thunderstorms are likely to cluster, with a higher threat for heavy downpours, possible localized flooding, and wind gusts up to 90 km/h.
Behind the front on Wednesday, temperatures are set to tumble across the area, with daytime highs expected to be several degrees below seasonal.
That will feel like quite the temperature tumble, especially after an extended period of unusual hot and humid September weather that saw highs soar into the 30s.
Prepare
Make sure to keep up-to-date on your local forecast information and alerts. If you are outdoors in an area with a severe weather threat, make sure you have a safety plan in place in case you need to get to shelter.
If a severe thunderstorm approaches your location, remain mindful of trees or tree limbs that loom near your home. Trees falling into buildings are a significant source of injury during strong storms. Try to avoid rooms where trees may cause damage during high winds.
The greatest danger in any thunderstorm is lightning. If you can hear thunder, you’re close enough to be struck by lightning.
