It seems like wintry weather is finally making its way to Ontario.

Residents are being advised of a late fall storm that will roll in early this week, bringing snow and freezing rain to much of the province.

In a recent social media post, Environment Canada’s predictions say the storm will hit the region starting Monday (Nov. 25) and continue into Tuesday.

Weather models from the European, Canadian and American systems show varying projections.

Four weather maps of Ontario showing the pressure pattern and location of rain, snow, and freezing rain for early Tuesday morning.

The European model (top-left image) predicts significant snow and freezing rain affecting regions in the Greater Toronto Area which includes Toronto, Brampton, Mississauga, Halton and Durham as well as Sudbury.

The Canadian model (bottom-left image) suggests heavier snow accumulation in areas such as Ottawa, Kingston and Barrie.

The American model (top-right image) points to lighter snowfall in western regions but still warns of freezing rain, particularly in London, Kitchener and Windsor.

The North American model (bottom-right image) shows a forecast similar to that of the American model. It points to freezing rain in specific areas, especially in the eastern regions of Ontario.

The accumulation of snow could range between five and 10 centimetres. In addition, it’s a possibility the stormy conditions will move into Wednesday bringing icy roads and reduced visibility.

With the storm still developing, Environment Canada says it’s too early to provide definitive details on the areas most affected. However, the weather agency will continue to monitor the situation closely.

Significant weather outlook for Ontario on Tuesday. 5-10 cm of snow is possible for parts of northeastern and central Ontario and towards Lake Ontario including Peterborough and Kingston. There is also a risk of freezing rain from Oshawa to Parry Sound east to Ottawa. Lake effect snow is also possible for the Dundalk Highlands including the Mount Forest area.

Significant weather outlook for Wednesday. Lake effect snow is likely for areas southeast of Georgian Bay and Lake Huron.
