Summer in September: Week of heat for southern ON

Sunday, August 30, 2015, 1:52 PM - As the final weekend of August winds down, the inevitable end of summer looms on the horizon. But this week will still offer the chance to soak up a few more summery days before trading in your flip flops.

Just as people are preparing to head back to school and return to their routines, parts of southern Ontario and Quebec can expect the longest stretch of hot, dry weather they've seen all summer.

A shifting pattern will see the jet stream push up to the north, triggering a massive upper level high pressure system to develop while a deepening trough moves in behind it through British Columbia and Alberta.

The same high pressure system will blankets parts of the eastern United States, tracking into Canada throughout the day on Monday.

While temperatures will sink well below-seasonal in the west, the east will reap the benefits -- in the form of heat, humidity and sunshine.

"Widespread parts of southern Ontario and southern Quebec can expect temperatures to feel like the mid-to-upper 30s with the humidex," says Weather Network meteorologist Tyler Hamilton.

Isolated thunderstorms and showers are possible over the next week, but forecasters are looking at a mainly rain-free period for the region.

Great news for those on vacation, or anyone simply looking to squeeze a few more drops of summer out of the season.

"Confidence is building that the provinces will see a stellar Labour day weekend, with temperatures well above seasonal," Hamilton says.

The fast-moving system will make its way into the Maritimes by Wednesday, bringing above seasonal temperatures to parts of the Atlantic provinces, with the exception of Newfoundland.
