The official start to summer is still a week away, but parts of Ontario have been feeling like the middle of July recently.
Temperatures climbed to the high 20s in some areas over the weekend, feeling even hotter with the humidity. That forced officials to issue a smog advisory on Sunday, which continued for much of the day on Monday.
Places like Ottawa, Trenton and North Bay even broke the daily temperature record on Monday with daytime highs around 30 degrees.
Tuesday will be a much fresher day across the province thanks to a cold front moving through.
"Rain developed ahead of the cold front Monday night and brought 10-20 mm to the Golden Horseshoe and parts of the GTA," says Gerald Cheng, a meteorologist at The Weather Network. "And the rain along with the risk of isolated thunderstorms will continue through part of the day on Tuesday."
The thunderstorms will be mostly non-severe in nature, but some places can expect heavy downpours at times.
Dark clouds and strong winds began moving through the region Tuesday afternoon.
There were also reports of nickle-sized hail in Newmarket and Brantford.
"Temperatures will also return to seasonal values and high pressure will remain in place for much of the week," notes Cheng.
The humidity and sticky conditions aren't expected to creep back in until the weekend.
