After a hot and dry weekend for much of the region, rising humidity continued to stifle the province for the start of the work week.
The humid airmass that moved in from the Gulf of Mexico prompted Environment Canada to issue a humidex advisory for areas in the southwest on Monday.
By the afternoon hours however, the advisory was dropped as a cold front slid through.
“The cold airmass also helped to trigger some thunderstorms in the Windsor area,” says Rob Davis, a meteorologist at The Weather Network.
Strong winds and heavy rain were reported throughout the day.
Meanwhile in Toronto, the heat continued to hang on.
“The city was the hotspot of the entire country, with temperatures reaching 33.5°C, feeling closer to 39 with the humidity,” explains Davis.
The heat certainly didn't smother the spirits of eager U2 fans lined up outside the Rogers Centre on Monday.
“We got some water and Gatorade. We brought umbrellas to keep us in the shade, we have our little hand fan, so we've done this a few times,” said one fan.
“We're prepared, lots of water. Hydrate, hydrate, hydrate,” said another person in line trying to stay cool.
Toronto was the hotspot of the country for the second day in a row on Tuesday as temperatures climbed to 33.1°C.
Significantly cooler and more comfortable conditions are expected on Wednesday and in some areas, temperatures could even be below seasonal values, says Davis.
“The break will be short lived however. The humidity will begin to creep back in by Saturday.”
And no significant rain is in the forecast either. A dry trend is expected to persist throughout the weekend. So far this month, only 4 mm of rain has been recorded at Toronto's Pearson International Airport. The average rainfall for July is close to 75 mm.
