Parts of Ontario will be hit with the first major snowfall of the season on Friday, with forecasts predicting 15 cm in the province’s northern regions.
And while conditions are comparatively mild in Southern Ontario to kick off the weekend, residents of the province’s most populous region might want to treat the conditions brewing to the north as something of a warning of what’s to come.
A vast swath of the province, including Timmins, Cochrane, and Kapuskasing, has been placed under a snowfall warning by Environment and Climate Change Canada (ECCC), with the government weather agency warning of “Snowfall with total amounts of about 15 cm.”
ECCC warns of intense snowfall creating “Near zero visibility at times” on Friday, set to taper off by late afternoon or early evening.
The sudden dump of snow is expected to make for treacherous travel conditions along Highway 11 and other local routes, with ECCC warning that highways, roads, and walkways will ” likely be difficult to navigate due to accumulating snow.”

The warning may not affect the densely populated regions to the south, but the system blasting these northern municipalities with early-November snow serves as a stern warning to Southern Ontario residents that the winter headaches are just around the corner.
The wait won’t be long for Toronto and the surrounding region, either.
Southern Ontario will get off relatively easy in comparison on Friday, with rain and temperatures maxing out at 11 degrees C in Toronto.
However, the relatively mild weather is predicted to come to a screeching halt in the days to come, bringing the first taste of snow for Toronto residents this season.
ECCC predicts temperatures to slide to -1 C in Toronto overnight Saturday, with a 30 per cent chance of rain showers or flurries.
Periods of snow or rain are expected to follow during the day on Sunday, Nov. 9, with temperatures falling to -5 C overnight, bringing a 60 per cent chance of flurries or rain showers.
Cold weather conditions are also on tap for the coming Monday, with a daytime high of 2 C and a 30 per cent chance of flurries or rain showers.

So, get that winter wardrobe back in rotation. You’re going to need to layer up before the deep freeze arrives.
