Strong and gusty winds possible later this afternoon and evening. A sharp and fast moving cold front will bring a sudden end to the warm air and sunshine being experienced across Southern Ontario today. This front will race into Southwestern Ontario this afternoon, and will reach the Golden Horseshoe area including Toronto by early this evening, then into Eastern Ontario later this evening. Strong and gusty winds along with showers and isolated thunderstorms will begin suddenly as the front goes through. Wind gusts of 80 to 85 km/h are quite possible in a few locales, with 90 km/h gusts not completely out of the question. These winds may be strong enough to cause some tree damage and associated local power outages in exposed areas. There is also some potential for isolated thunderstorms to briefly reach severe limits with wind gusts of 90 km/h during brief very heavy downpours later this afternoon into early this evening as the cold front blasts through. Environment Canada is closely monitoring the situation. Severe thunderstorm watches or warnings may be issued as required later today.
