Cooldown in southern Ontario leads to chance of flurries for some
A noticeably chilly pattern has descended on the Great Lakes, bringing the region some of its coldest temperatures since the spring, along with the chance of flurries for higher elevations in parts of southern Ontario
Ready or not, October snows can happen!
For southern Ontario, fortunately, most areas won't be seeing the white stuff, just yet, but higher elevations could see some flurries through Tuesday.
DON’T MISS: Ready for the chill? Southern Ontario's coldest day since April looms
A noticeably chilly pattern has descended on the Great Lakes, bringing the region some of the coldest temperatures we’ve seen since spring.
Make sure you are dressed warmly if you're planning on venturing outdoors, even if it's just to get to your parked vehicle.
Tuesday: Cooldown brings snow chance for some
Lake-effect showers snuck their way down from Georgian Bay and Lake Huron on Monday evening, and may continue to sprinkle across through Tuesday. That will bring a risk for mixed precipitation for some higher-elevations areas on the escarpment and toward cottage country, where some flurries are expected heading into Tuesday.

Northerly winds will help keep temperatures unseasonably cold on Tuesday.
Temperatures will struggle to reach the double digits throughout southern Ontario through Tuesday, with even chillier readings expected beneath more organized precipitation across eastern portions of the province.
The last time we saw single-digit highs across southern Ontario include:
April 24 - Windsor
April 25 - Toronto, Hamilton
April 25 - Kingston
April 30 - Ottawa
If Toronto fails to hit 10°C Tuesday, it'll be our first day mired in the single digits since April 25. Ottawa is looking at its coldest day since April 5.
Right now, it looks like the Dundalk Highlands (elevation: 526 metres), north of Orangeville and Algonquin, are at risk for a coating of snowfall beginning early Tuesday.
Regions north of Orangeville along Highway 10, including Shelburne, are at the highest risk of seeing their first light accumulating snowfall of the season.
Temperatures hovering a couple of degrees above freezing through the overnight hours across higher terrain mean there is uncertainty in precipitation type, although it is unlikely we’ll see significant snowfall totals anywhere across southern Ontario.
It’s not a pattern that will last, however, as there’s now a strong signal for above-seasonal temperatures beginning late week, with temperatures even spiking above 20 C.
Next weekend looks exceptional for late-October standards, with a massive ridge of high pressure all across southern Ontario.
