Supercells possible with severe storm setup in northwestern Ontario
Folks across northwestern Ontario should pay close attention to the weather on Tuesday as severe thunderstorms will be possible, alongside one or two tornadoes
With Ontario getting a break from the heat to start the week, but will return soon, northwestern sections of the province will be getting into the severe weather risk on Tuesday.
In fact, multiple days of thunderstorms are expected in northern Ontario as a boundary stalls over the region. Tuesday could see severe thunderstorms push into the region, with strong winds, heavy downpours and hail as threats. Some areas near the Ontario-Minnesota border, west of Thunder Bay, could also see supercells, so one or two tornadoes can't be ruled out.
DON’T MISS: U.S heat will soon spill into Eastern Canada, bringing back 30 C weather
Tuesday's storm risk also extends back into southern Manitoba, with a severe chance in southeastern sections.
Make sure you keep an eye on the radar––especially if you have outdoor plans––and stay aware of any severe weather watches or warnings issued in your area.
Tuesday and Wednesday: Multiple storm opportunities
An active weather boundary moved into northern Ontario on Tuesday, will stall for multiple days this week--bringing several opportunities for severe weather.

As the day progresses on Tuesday, from late afternoon through the evening, storms could pop up from Dryden to Fort Hope, possibly becoming marginally severe with two-centimetre hail possible.
If you are in the region, please stay on top of severe weather alerts and know what to do and where to go in the event severe weather approaches.
Forecasters are also closely watching the Minnesota-Canada border, just west of Thunder Bay, for possible rotating supercells and one or two tornadoes.
On Wednesday, forecasters will then turn their attention to the potential for another cluster of storms to develop along the Lake Superior shores.
The area at risk will stretch from Thunder Bay through Wednesday morning to Sault Ste. Marie by the afternoon and evening.
There is some uncertainty on how much thunderstorm energy will develop and the severe potential at this time. But heavy rainfall and frequent lightning will be the main threats.
Heavy rain, especially, will be one of the main threats for northwestern Ontario. Localized flooding concerns are there with training thunderstorm potential.
After a warm start to the week, a strong cold front will track across the region with much cooler weather late next week and on the weekend, continuing well into the first week of August, especially in eastern areas.
Warmer weather is expected for the second week of August, however.
