Snowfall Warning posted for southern Quebec

A few centimetres of  fluffy light snow overnight made for a slick Wednesday morning commute in Montreal. Like a broken record this month to date, there were numerous accidents reported. Roads will be in even worse shape for the Wednesday evening drive home, as moderate snow is forecast for the Montreal region. (Valley Weather)

 An Alberta Clipper storm system will slide across the Great Lakes on Wednesday and down the St. Lawrence Valley. An area of steady snow is currently approaching the Montreal region, with as much as 10cm expected over the next few hours. The snow will become lighter overnight and taper off on Thursday, with another 5-10cm possible.

Widespread snowfall warnings are in effect from southern Ontario into southern Quebec. On the backside of the low pressure, winds will increase sharply on Thursday, gusting up to 60km/h. The temperature will fall as well from early morning highs near the freezing point to -10C (14F) by afternoon. The gusty winds will produce areas of blowing snow, along with significant windchill values, into the minus 20s.

Travel was already difficult on Wednesday morning, with numerous accidents reported in the region. One accident closed Highway 50 near Mirabel in both directions. Roads will continue to be in poor shape during the Wednesday afternoon commute in Montreal, with moderate snow and icy road surfaces. In eastern Ontario, moderate snow resulted in most regions canceling school bus service.

Conditions should improve Thursday afternoon, but the weather will remain breezy and cold.
