Environment Canada has issued a severe thunderstorm watch for our region.

Thunderstorms this afternoon have the potential to quickly become severe and generally track eastward. Thunderstorms are generally expected to be isolated early this afternoon, however, a organized line of thunderstorms may develop later this afternoon.

Wind gusts up to 100 km/h are possible. 

According to CTV London Meteorologist Julie Atchison, some rainfall is expected this holiday weekend in midwestern Ontario, but it’s not a wash out.

"There will be some showers and a few spotty thunderstorms,” said Atchison, adding Saturday’s weather could be “unsettled.”

“It will be cooler and drier Sunday, back into some nice sunshine as we head into Sunday afternoon,” said Atchison. “Holiday Monday, that’s the day! It’s looking absolutely perfect with sunshine right across the region.”
