Snow arrived in Ontario , over 100 cm expected
Difficult driving conditions continue through this weekend across portions of Ontario as powerful snow squalls continue whipping off all five of the Great Lakes, leading to impressive, multi-day accumulations through Sunday.
Powerful snow squalls could produce up to or more than 100 cm of snow across parts of Ontario through this weekend.Chilly air pouring over the Great Lakes for the past few days has given rise to multiple potent snow squalls throughout the region. Bracebridge, Ont., reported 55 cm of snow through Friday evening.Cold air is a key ingredient in lake-effect snow production. A strong temperature gradient between the frigid air above and the warm waters below creates convection, resulting in bands of lake-effect snow. Thundersnow is also possible in some of the heaviest snow squalls. Minus 10 Deg C with 60km winds
Road closures are possible as steep accumulations and near-whiteout conditions occur beneath the heavier bands of snow that roll inland off the lakes. Snow squalls can produce a rapid change in conditions over short distances.These potent bands of lake-effect snow will continue through Sunday, with some communities such as Gravenhurst in line to potentially see up to or more than 100 cm of snow by the time it ends. Hardest-hit communities could still see an additional 40-50 cm of snow. As a reminder, lake-effect snowfall is a highly localized, high-impact weather event.
