Severe thunderstorms swing through Thursday, Environment Canada says – The London Free Press

Another summer storm is on the way for most of Southwestern Ontario.

Environment Canada is urging everyone to be on the lookout Thursday afternoon and evening as scattered thunderstorms crop up across the region.

Storm cells are likely to develop near Windsor, east of Lake Huron and north to Georgian Bay by midday, the national weather agency said. The storms will track east across southern Ontario through the afternoon and evening.

London, Chatham-Kent, Sarnia-Lambton and Middlesex, Elgin, Oxford, Huron, Perth and Bruce counties are under a severe thunderstorm warning.

The system is capable of creating nickel-sized hail, Environment Canada said. Wind gusts strong enough snap tree branches, down power lines and send debris airborne are expected. Parts of the region might see torrential rain, lightning and hail as the thunderstorms pass through.

Environment Canada is warning people to stay indoors if they see lightning or hear thunder. The storms are expected to subside by the evening.
