September 14, 2011 — After a late blast of summer heat in Ontario, temperatures are cooling significantly.

It was a stormy start to the day in parts of Ontario on Tuesday. People around Georgian Bay woke up to rumbles of thunder and frequent lightning.

“The first of two cold fronts slid through during the morning hours sparking isolated thunderstorms in some areas,” says Rob Davis, a meteorologist at The Weather Network. “And the thunderstorm activity redeveloped along that same cold front during the afternoon and evening hours as well.”

A severe thunderstorm warning was issued for the city of Ottawa, where heavy rain, strong winds and large hail were reported.

The line of severe storms moved through southern Quebec as well prompting a brief tornado warning for the Laval region. Radar showed a storm cell with the potential to produce a tornado, but no touchdowns were reported.

“Another thing to consider is the significant cool down,” warns Davis. “A second cold front moving through on Wednesday will send daytime highs plunging. By Thursday, Ontarians will be waking up to single digit temperatures.”

Temperatures have also dipped across the Prairies and in parts of northern Manitoba, a rain/snow mix was reported Tuesday morning.
