Environment Canada warns of an increasing possibility for a "widespread snowfall event" in southwestern Ontario this weekend, which could bring the first serious snow of the season – up to 15 centimetres of it – to the Toronto, Hamilton, Kitchener-Waterloo and Windsor areas.
In a statement published Friday morning, the forecasting service notes that a disturbance moving out of the south-central United States is expected to move northeast toward the Great Lakes, arcing across to central New York state by Sunday morning.
Bands of snow on the leading edges of this system are forecast to hit southwestern Ontario on Friday and spread northeast on Saturday.
Environment Canada is forecasting 10 to 15 cm of snow by Saturday night through the Windsor-Toronto corridor, with higher amounts around the west end of Lake Ontario and the north shore of Lake Erie.
