UPDATE: Severe Thunderstorm Watch, Warning Ended

Environment Canada has ended all severe thunderstorm watches for the region.

The weather agency issued the alert Thursday afternoon for all of southern Ontario including London-Middlesex, Elgin County, Oxford County, Chatham-Kent, and Windsor-Essex. Forecasters said conditions were favourable for the development of thunderstorms on Thursday afternoon and evening.

“The threat of severe thunderstorms this afternoon and early this evening is associated with a cold front moving across Southern Ontario,” Environment Canada says. “Thunderstorms are also possible well in advance of the front.”

A severe thunderstorm warning was also briefly issued for the London Middlesex area between 5pm and 7pm, before it was downgraded to a watch. All severe thunderstorm watches were ended just before 9pm.
