A heat warning remains in effect stretching from Windsor-Essex and Chatham-Kent through Lambton County as well as London and Middlesex.
The chance for scattered showers and thunderstorms starts Tuesday morning and moves into the afternoon, according to CTV News London Meteorologist Julie Atchison.
“We’ll pick up a lot of sunshine as well throughout the day which will push the temperature up into the upper 20s in through Grey and Bruce and Huron-Perth Counties — in London, we could hit 31 C Tuesday afternoon. That would be the hottest day of the month,” Atchison added.
The last time it was this hot in London was Aug.1, when the temp hit 30.8 C.
