Tuesday marks the final full day of summer. And Ontarians will be celebrating the end of the season with true summer-like conditions.
“High pressure is in place and is dominating the region and that's why we're experiencing the fair weather,” says Gerald Cheng, a meteorologist here at The Weather Network.
Despite a few showers throughout the weekend, most places saw daytime highs near the 20 degree mark. While temperatures were a bit cooler on Monday, they're set to heat up once again today.
“Humidex values will return to southern Ontario for the last day of summer,” says Cheng.
Toronto in particular will see temperatures climb to 25°C, feeling more like the 30's with the humidity.
And that summer heat will help to fuel thunderstorms late in the day.
“We'll get hit by the same system that's been affecting the Prairies. Showers will pass through the Greater Toronto Area through the evening and overnight hours Tuesday,” explains Cheng.
While there's still three and a half months of the year left, Toronto could see its warmest year on record. So far, the city's average temperature for the year is 11.2°C. Since record keeping began in 1938, the record for the warmest year was set back in 1998 with an average temperature of 10.2.
