Most Ontarians enjoyed a perfect Canada Day forecast on Friday. Between high temperatures and moderate humidity, there wasn't much to complain about. During the evening hours, temperatures hovered in the low to mid 20s, making it ideal weather for watching fireworks.
The comfortable conditions didn't last long however. By Saturday, some areas saw the humidex reach as high as 45. The humidity and rising temperatures were the perfect ingredients for active weather in parts of the province Saturday evening. A severe thunderstorm watch was issued by Environment Canada for areas in the southwest. Large hail and winds gusting over 100km/h damaged trees and power lines in places like, Windsor, London, Leamington and Fergus.
Power outages from the storm persisted into Monday morning in Guelph and Leamington. Crews were out moving trees and branches from lines and also replacing transformers.
The thunderstorm risk continues in parts of northwestern Ontario Monday. Damaging winds, heavy downpours and large hail are the main threats with this system.
This is part of the same system that brought a line of severe thunderstorms to the Prairies over the weekend.
