Snow and blowing snow Wednesday.
An area of low pressure from Kansas is forecast to track south of the Lower Great Lakes on Wednesday. This system is expected to generate snow and local blowing snow for Wednesday for regions just north of Lake Erie and across the Niagara region where winter storm warnings are in effect. Snowfall will be somewhat less from Southern Lake Huron across the Greater Toronto area to Ottawa where up to 10 cm is possible. Amounts will trail off to 5 cm north of this tier of regions.
Although most of the snow will fall during the day Wednesday, some wet snow is likely just prior to the changeover to snow Wednesday morning as colder air settles in. This could create rather hazardous commuting conditions from the Greater Toronto area southwestwards as roads may become slippery with some of the initial accumulating snow turning to ice. Motorists are advised to exercise caution when travelling or commuting due to poor visibilities in snow and blowing snow and slippery roads.
