Stormy week ahead for winter weary Montreal

A winter storm will produce heavy snow in Montreal from Tuesday afternoon into Wednesday morning. Current indications are that 25 to 40cm of snow may fall in the St. Lawrence Valley. Strong winds will accompany the snow, greatly reducing visibility. Travel will become extremely challenging across the entire region. Adjust your plans if possible. (AccuWeather Photo)

Winter Storm Watch for Eastern Ontario.
Special Weather Statement for Southern Quebec.

A major winter storm is poised to impact southern Ontario and Quebec from Tuesday through Thursday this week. High pressure will remain in control of the weather in Montreal through early Tuesday, with clear and cold conditions. Clouds will increase on Tuesday morning as low pressure moves from the Ohio Valley into New York State. A second area of low pressure is expected to develop over Delaware and move towards southern New England on Wednesday.

The combination of these two storms will produce a wide area of heavy snow and sleet from southern Ontario across Quebec and New England. Current thinking is that the heaviest snow will fall in the St. Lawrence Valley from Kingston to Quebec City. In this corridor, amounts could easily exceed 30cm through Wednesday. Accompanying the snow will be gusty northeast winds in excess of 50km/h, producing areas of blowing and drifting snow. In Montreal, visibility will be severely reduced in falling and blowing snow through midday Wednesday. Travel across eastern Ontario and southwest Quebec will become extremely difficult Tuesday night.

A winter storm warning will likely be issued for Montreal early Monday morning. Look for additional updates on the storm beginning Monday morning.
