"We're seeing an explosive cluster of storms drifting across the Midwest U.S., with frequent lightning and damaging winds likely as they cross over into southwestern Ontario this morning," said Jessie Uppal, a meteorologist at The Weather Network.
As of Thursday morning, a severe thunderstorm watch has been put in place for Elgin, London-Middlesex, Sarnia-Lambton and Windsor-Essex-Chatham-Kent.*
After the storm passes, temperatures are expected to drop below seasonal, so don't expect hot sunny days for the long weekend.
