The fall season is inching closer and this weekend marks the last unofficial long weekend of the summer. In southern Ontario however, the heat is hanging on for a little while longer.
Environment Canada issued a humidex advisory for Windsor, Essex, and Chatham-Kent on Thursday. By Friday morning, the advisory had been extended right through to Parry Sound and the Greater Toronto Area including York Region and Durham Region. Temperatures are expected to climb into the 30s, feeling more like the low 40s with humidity.
“And the heat will linger on Saturday, before a cool down early next week,” says Brian Dillon, a meteorologist at The Weather Network.
A smog advisory is also in place in southwestern Ontario. Residents are encouraged to spare the air by taking public transit or car pooling.
Additionally a heat advisory has been issued for both the City of Hamilton and the Halton region. Residents are being asked to relax and stay indoors.
Health officials say people with respiratory problems should avoid strenuous activities and limit time spent outside.
The rising heat and humidity helped to fuel thunderstorms across the region on Thursday and the potential for more storms continues throughout the day Friday, notes Dillon.
August has been an active month for severe conditions across Ontario and the tornado tally continues to climb.
13 tornadoes have been confirmed this season, with the most powerful hitting the town of Goderich over a week ago. The F3 twister devastated the community and left the area looking like a war zone.
A state of emergency remains in place to ensure certain buildings are safe. Mayor Deb Shewfelt says they decided to err on the side of caution and will keep parts of the downtown closed while recovery efforts continue.
After a hot and humid start to the Labour Day long weekend temperatures will cool significantly for holiday Monday.
