|Low pressure is forecast to intensify rapidly off the Maine coast late Sunday, delivering Montreal the largest snowstorm of the winter so far. (AccuWeather.com)|
Winter storm warnings are in effect for all of New England and New York for similar conditions. Air travel will likely become very difficult across the northeast US and eastern Canada by late Sunday. Any unnecessary road travel outside metro regions should be postponed Sunday. If the forecast conditions develop as expected, this will be the most significant snowstorm of the season so far in Montreal. Temperatures will remain cold throughout the storm here in the St. Lawrence Valley. The high on Sunday in Montreal will be near -6C (21F), with the overnight low near -8C (18F).
We will get a brief break on Tuesday, before another storm arrives Wednesday with more snow for Montreal.
