Cold here to stay in Montreal

The cold is here to stay in Montreal, with perhaps some mild air for Christmas Eve. Otherwise expect below freezing temperatures for the balance of the month. (AccuWeather)
Snow squalls Thursday night in Montreal dropped a quick 2 to 5cm of fresh snow on the city. In its wake, much colder air has arrived this morning, with temperatures in the -9C to -5C (16 to 23F) range across southern Quebec. Gusty northwest winds are making it feel even colder. Expect very little rise in the mercury today, with a cold night forecast into Saturday morning. Montreal and southern Quebec will likely see the coldest morning of the season, dropping to -15C (5F). The winter weather stretches from coast to coast this morning. Snow is forecast in Vancouver, with over 10cm expected. Bitter cold stretches across the Rockies into the Prairies, as cold as -30C (-22F). Across the Great Lakes, lake effect snow has dropped over 30cm in Ontario and New York, with more forecast today. The snow resulted in numerous multi-vehicle collisions in Michigan, Ohio and Pennsylvania.

Disruptive snow for Montreal for Monday commute
After Thursday's high of 3C (39F) in Montreal, I don`t see above freezing temperatures returning until Christmas Eve. Up until then, expect periods of snow along with a reinforcing shot of cold air next week. For the short-term, high pressure will nose into Quebec today with clearing skies and cold temperatures. The dry weather will persist into early Sunday. Late Sunday, low pressure and a warm front will approach southern Quebec. Expect a period of moderate snow into the Monday morning commute in Montreal. Current indications are for 10 to 15cm of snow, but it is another difficult forecast with multiple factors involved. After the snow, arctic air will arrive next week, with highs no better than -9C (16F) by Wednesday.
