Brief period of heavy snow for Montreal - eastern Ontario

The first of two cold fronts crossed the region late Wednesday with a period of very light snow in Montreal with 1 to 2cm. It remains cloudy this morning and cold with current temperatures of -6C on L'Ile Perrot and -5C at Trudeau Airport. Temperatures will warm to -1C today in advance of a potent cold front that will enter the region by 3pm. Look for snow ahead of the front across eastern Ontario and southern Quebec beginning by the noon hour and tapering off this evening. There could be a brief period of heavy snow and strong winds with the arctic front as it passes Montreal by 4pm. Otherwise look for light snow with accumulations of 2 to 5cm in the city and perhaps as much as 10cm in the mountains of the Townships, Vermont and New York. Again as I said yesterday, this will not be a storm, but it is the first snow events of the year so travel could be affected. Visibility in the heaviest of squalls may be reduced to near zero in falling and blowing snow. Skies will clear by midnight and it will be very cold with lows between -12C in metro areas and -18C in the mountains north and south of Montreal. Friday will be sunny and cold with highs near -8C. We are still looking at milder air by Sunday but with clouds and showers.
