Big temperature swing - more light snow for Montreal

Snowfall forecast from AccuWeather.com

Another shot of light snow or freezing drizzle is expected for southern Quebec as we head into this weekend. We are quite cold this morning across the western suburbs of Montreal with temperatures between -12C and -15C (5 to 10F). Expect a sunny, chilly day today with highs reaching -2C (29F) by late in the day. Clouds will be on the increase all day as a warm front lifts north from the Ohio Valley. Low pressure will move along the front as well passing well south of Montreal. Some light snow will develop this evening and mix with freezing rain overnight. A general 2-3cm is possible for metro Montreal, very similar to Wednesday night. More snow is expected further south and east along the Maine border as well as northeast of Quebec City. Temperatures will eventually rise above freezing on Saturday to around 2C (36F) with showers likely. Another strong cold front will cross the region late in the day Saturday with a round of snow showers before temperatures fall back down below freezing. Sunday and Monday look fair but cold with highs near -7C (19F).

Looking ahead into early next week, an active period of weather is possible with the potential for an east coast storm by the middle of the work week. Temperatures across North America will be above normal as the cold air retreats well to the north and milder Pacific air takes over. As far as the east coast storm goes, there is the chance for significant snow or rain depending on the track. It will bear watching. Look for updates on this blog over the weekend.
