Environment Canada has ended a severe thunderstorm watch for London-Middlesex.
However, a heat warning remains in effect for London-Middesex, Parkhill, Strathroy, and Komoka.
Environment Canada says the heat warning will likely continue through Thursday. Seasonal temperatures should return by Friday.
As a reminder, Environment Canada says, during these hot conditions, people should be drinking plenty of liquids - especially water, and should never leave people or pets in a parked vehicle.
