Snow squall warnings still in effect for parts of southern Ontario

Environment Canada's snow squall warnings remain in effect for a large part of southwestern Ontario on Jan. 3, 2025.

Snow squall warnings in southern Ontario remain in effect Friday, with as much as 60 centimetres expected by Saturday evening in some areas.

The lake effect snow will be felt most by areas along Lake Huron, including Kincardine, Hanover, Saugeen Shores, southern Bruce County, Dundalk, and southern Grey County.

Environment Canada says the heaviest periods of snowfall in those areas are expected tonight as stationary snow squall bands develop.

“Snow squalls cause weather conditions to vary considerably; changes from clear skies to heavy snow within just a few kilometres are common. Travel is expected to be hazardous due to reduced visibility. Road closures are possible,” the national weather service said in their warning.

Weather warnings are also still in place for Barrie, Collingwood, Midland, northern York Region, Newmarket, and northern Durham Region, but those areas are only expected to get five to 10 centimetres of accumulation.

Much of southwestern Ontario is also under a snow squall watch, with total accumulations expected in the 20-to-35-centimetre range by Saturday evening.

The weather alerts north and west of Toronto come a day after those areas were hit with a blast of winter weather, with total snowfall in some areas forecasted to reach the 60-cm mark.

Whiteout conditions were reported on some highways and the OPP said they responded to several crashes and collisions due to the weather. No injuries or fatalities were reported.

Toronto only got a light dusting Thursday amid a 70 per cent chance of flurries, which persists on Friday and into next week. No weather advisories are currently in effect for the city.

Friday’s high will reach 1 C and the low will drop to – 6 C amid a mix of sun and cloud.
