The region is expected to see multiple bouts of storms Monday night and Tuesday, potentially becoming severe. Large hail, strong wind gusts and heavy rainfall will be the primary risks associated with any that form. As well, there is a low, but non-zero tornado threat.

It will be important to stay on top of the weather watches and warnings in your area, as conditions can change quickly when severe weather hits.

Monday night and Tuesday: Severe thunderstorm risk resurfaces in northwestern Ontario

A couple rounds of rain, heavy at times, and thunderstorms will track across northwestern Ontario Monday night through Tuesday. There will be a severe storm and tornadic threat.

There will be multiple rounds of storms. The first bout will be a line of rain and storms ahead of a warm front and low-pressure system trekking into northwestern Ontario.

A second and more potent round of thunderstorms will begin to track in mid-afternoon Tuesday as the cold front slides in.

There will be strong, upper-level support, accompanied by deep moisture and the presence of high atmospheric energy.

Good wind shear will be present, providing the final ingredient for the potential for supercell thunderstorms, which include a risk of a tornado.

For those to come to fruition, the critical timing will be between 6 and 9 p.m.

As such, all severe weather parameters are possible including heavy rain, a localized flood risk, large hail, strong wind gusts and a tornado risk.
