Severe thunderstorms likely to hit parts of Ontario and Quebec Thursday

Along with the humidity, comes the possibility for severe thunderstorms. Ontario has the potential to see the most severe weather of the season so far on Thursday

Muggy air will return to the province with the warm temperatures, and while folks may get a chance to soak up some sun, it won't last all week.

With building heat and high humidity comes instability in the atmosphere. A cold-front moving through the province will trigger a risk for thunderstorms, with the chance for some to become severe.

Thursday has the potential to be the most severe day of the season so far for southern Ontario and western Quebec, so 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.

A strong cold-front pushing eastward through the lower Great Lakes region this week will clash with the warm, humid air, triggering widespread rain and embedded thunderstorms in its path.

The hot and humid air mass settling over the region will bring copious amounts of thunderstorm energy for storms to develop from.

Torrential rain, strong wind gusts, large hail, and even a tornado or two are strong possibilities for Thursday. BE sure to be weather aware on Thursday as damage is possible given the severity of this upcoming system.

The dreary, stormy weather will stick around through the overnight Thursday, giving Friday a less-than-ideal start.
