Below normal temperatures expected for Montreal

A very slow moving area of low pressure centered over Ontario will drift southeast into Maine by the weekend. Cloudy, cool weather with periods of rain and even wet snow is possible into the weekend for Montreal and southern Quebec. (AccuWeather Image)
The stubborn, vertically stacked low pressure over the Great Lakes continues to slowly move east from Ontario into Quebec. This low has been responsible for a cold, moist dome of air over the region stretching from the upper Midwest into Quebec and east to New England and Atlantic Canada. The result has been temperatures 5 to 10 degrees below normal as well as periodic showers and even wet snow. On Wednesday, more heavy showers with even small hail occurred across metro Montreal bringing the three day rain total at my home on L'Ile Perrot up to 36.8mm.

Light rain is falling again this morning with a very cold late April temperature of 1C (34F). Gusty northwest winds of 30-50km/h will make it feel even colder today. Light wet snow is being reported across several portions of eastern Ontario and northern New York this morning, so it would not surprise me one bit if we saw a snowflake or two today and tonight. Temperatures today will reach 7C (45F) in the showers. Tonight, more of the same, rain and snow showers and a low of 0C (32F). Sadly Friday through the weekend looks identical, perhaps a few more breaks of sunshine by Sunday. Temperatures will remain below normal with lows of 0 to 3C (32 to 38F) and daytime highs of 8 to 12C (47 to 54F).
