Photos: Damaging storms sweep northeastern Ontario

Monday, July 2, 2018, 2:33 PM - The long weekend was a stormy one across parts of northern Ontario, with overnight and predawn thunderstorms sparking tornado watches and warnings at time Saturday and Sunday. Most tornadoes in Canada occur in the afternoon or evening, but they can happen at any time of the day provided the conditions are right.

"In this case, we had an already existing cluster of energy which originated in Montana on Thursday. This energy rode a ‘wave’ on the top end of the incoming extreme heat and humidity," Weather Network meteorologist Kevin MacKay says. "Even though this occurred overnight, there was enough energy being supplied by the new airmass to fuel the storms, taking on the role which usually played by daytime heating."

Here's a look at how those tornado-warned storms looked.
