July 11, 2010 — Skies suddenly darkened as severe thunderstorms fired up in southern Ontario on Sunday afternoon.

A picture-perfect Saturday in southern Ontario gave way to a stormy Sunday. Our StormLine (1-800-463-9463) and Facebook page were quickly flooded with reports of torrential rain, constant lightning, and powerful wind gusts.

Many calls, comments and viewer photos came from Guelph, where there was enough hail to cover the lawn in some neighbourhoods. Other severe cells popped up in Wasaga Beach, Barrie and Ingersoll.

What caused the rapid switch from gorgeous to gloomy? The air was warm because of the sunshine and daytime heating. Then it collided with cool air as breezes converged off the Great Lakes, triggering the thunderstorms, explains Weather Network meteorologist Michelle Cassar.

A severe thunderstorm watch covered most of southern Ontario. Storms moved quickly though some areas, and the sunshine was pushing through the clouds soon after the downpours. Drivers reported low visibility on the roads at times. A funnel cloud was spotted near Cawthra Road in Mississagua.
