Get ready for a major chilly change across Ontario next week
A lobe of Arctic air will spill over Ontario next week, bringing the province unseasonably cold temperatures and even a threat for snow.
If you’ve been snubbing your sweaters and avoiding the season’s first running of the heat, your dreams of a final breath of summer might come to a rude end before long.
A solid dose of Arctic air will spill across Ontario by the middle of next week, making things feel more like November and possibly even bringing some snow to parts of the province.

Canada will endure a stark divide between the west and the east heading into next week. British Columbia will continue enjoying beautiful skies and summer-like warmth as a steep ridge builds over Western Canada.
Extremes beget extremes, unfortunately, and Ontario drew the short straw on this upcoming temperature split.
An upper-level low swooping south from the Arctic will start spreading over Ontario early next week. This lobe of chilly air will arrive in southern Ontario by Tuesday and stick around for a couple of days.

We’ll see temperatures plunge across northern sections of the province on Monday and Tuesday, with some communities struggling to push their daytime high temperatures above the freezing mark.
MUST SEE: Here’s what you need to prepare for inevitable icy weather
By midweek, daytime highs in Toronto will only reach the upper single digits, with even chillier conditions expected for folks up toward cottage country.
The upcoming bout of cold air is more like what you’d expect to see in November than the middle of October. Most of Ontario will see daytime highs come in 5 to 8 degrees below seasonal by the middle of the week.
Fall Forecast revisited: The good, the bad and the ugly
We’re also on the lookout for the chance for snow across the province.
Temperatures will be cold enough—and the atmospheric pattern favourable enough—that any precipitation that moves through the region could fall as wet snow. The potential for snow could even stretch into cottage country and southern Ontario.
