The start of the first weekend of 2025 is going to be a very snowy one.
Lake effect snow could dump as much as 60 centimetres over much of midwestern Ontario by Saturday night.
Environment Canada has a snow squall warning in effect for Huron, Perth, Grey, south Bruce, and north Wellington countries.
The snow squalls are expected to redevelop Friday morning and continue throughout the day Saturday.
The heaviest snow bands will come Friday night as squalls will become stationary over the area, dropping up to 30 centimetres.
Driving will be hazardous due to the rapidly accumulating snow and reduced visibility from blowing snow.
"Snow squalls cause weather conditions to vary considerably; changes from clear skies to heavy snow within just a few kilometres are common," Environment Canada said. "Road closures are possible. Be prepared to adjust your driving with changing road conditions.
Both Bruce and Grey counties had declared significant weather events. The declaration is meant to let the public know that due to the current or forecasted conditions, it may take longer than usual to bring the condition of the roads back to a state of repair. Grey County ended its declaration around 11:30 a.m.
Bruce Peninsula and northern Grey County will be spared the worst of the snow with only 5 to 10 additional centimetres expected. The national weather agency anticipates snow squalls in those areas will move south late Friday this morning. However, the lake effect snow will return this weekend over some areas.
