Ontario recorded its first snow of the season over the weekend, arriving weeks before the official end of summer, and reminding locals that the brutally cold winter months loom just ahead.

Much of Ontario experienced fall-like temperatures during the second weekend of September. However, some northern areas of the province saw temperatures dip to the low single digits, and there are even confirmed reports of snow.

Environment and Climate Change Canada (ECCC) reported on Saturday evening that snow had been spotted on highways north of North Bay — sharing a webcam image captured at the intersection of Highway 63 and Highway 533.

OH Snnnoooowwwww ❄️❄️❄️!!!

📢 Snow is being reported over parts of northeastern ON this evening.

While ECCC stated that no accumulation was expected, some collection was reported on grass and trees.

Yes, we had a little accumulation later in the evening. All gone now.

Similar conditions were reported as far south as Huntsville, around 2.5 hours outside of Toronto.

Looks like a rain-snow mix has worked its way as far south as Huntsville (Looking at the street light). Don’t be surprised if you see some wet snow across parts of Cottage Country overnight as temps continue to drop and this pushes SE. #ONStorm #ONwx pic.twitter.com/UEJ60ungoq

The lack of accumulation on roads and other paved surfaces means that many meteorologists may not classify this taste of winter as the official first snowfall of the season.

While early September snow in Ontario might have some people thinking the summer is making an early exit, the weather is expected to make a dramatic turnaround and bring another blast of heat to close out the season.

The same areas of Northern Ontario that witnessed snow on the weekend will be the first to experience high temps starting Tuesday, with the system to arrive in Southern Ontario the following day.

Thermometers in some areas of the province will exceed the 30 C mark this week, marking a total 180 from the brisk weather seen just days earlier.
