Environment Canada has ended its a severe thunderstorm watch for the London region, as the national weather agency was monitoring a cold front Thursday morning.
Conditions were favourable for the development of severe thunderstorms that may be capable of producing wind gusts of up to 100 km/h, large hail and heavy rain.
The watch — calling for rainfall amounts in the 30 to 50 mm range — was in place for London, Parkhill, Strathroy, Komoka, and parts of Middlesex County.
At one point Thursday morning, Environment Canada had issued a thunderstorm warning as they were tracking a system west of London.
As forecasters expected, the system cleared out of the area by Thursday afternoon.
