Heavy rain and strong winds moved through the region with downed trees reported in the Windsor area.

Camera operator Mark Rozitis captured some of the damage done by the storms including damage to backyard fences and furniture.

Weather Network meteorologist and Storm Hunter Mark Robinson was also out in the thick of the storms when he captured this amazing shelf cloud near Sarnia.

The thunderstorm risk continues on Wednesday, with isolated severe storms possible through the afternoon and evening hours.

Up to 30 mm of rain is forecast in the hardest hit places, with locally higher amounts possible in thunderstorms.

The greatest risk for severe storms Wednesday will be along the Huron shores.

"Any storms that fire up in southern Ontario will be big rain makers and slow movers," says Weather Network meteorologist Kelly Sonnenburg. "Localized flash flooding could occur."

Rising heat and humidity will also give parts of the province a break from the autumn-like weather.

"Most areas will not see true summer heat however," says Weather Network meteorologist Dr. Doug Gillham. "The increasing humidity will make it feel muggier and keep overnight temperatures from dropping off, but clouds and scattered showers and thunderstorms will also limit how warm it can get during the day."

PATTERN CHANGE: Dr. Doug Gillham provides a detailed analysis of the weather for the end of August.
