Snowy weekend for Montreal

Welcome to the wild weather world known as the month of March. This month swings between record warmth and snowstorms, sometimes within a 48 hour period. Just this week, after such a cold six weeks, Montreal almost squeezed out a record high on Tuesday. The mercury soared to plus 8C (48F), short of the 10.3C record set in 1977. That was at Trudeau Airport, other locations in southern Quebec including L'Ile Perrot and St. Anicet actually went above the record high reaching 11C (52F). But, just 36 hours later here we are shivering again at -12C (10F) with a gusty wind.

We can expect a partly cloudy Friday with temperatures warming to -3C (27F). Clouds will thicken this afternoon as a slow moving weak area of low pressure moves east from northwest Ontario. This system will bring very light snow or freezing drizzle overnight to eastern Ontario and southern Quebec. On Saturday, deeper moisture will stream northward from developing low pressure in the Mississippi Valley. This will likely produce a period of wet snow mixed with rain. The precipitation will change over to all snow by the evening and overnight hours Saturday. Montreal and points north of the city can expect 5-10cm of wet snow. South and east of Montreal across the Townships and into Maine closer to 20cm could fall. On Sunday precipitation will taper off to a few flurries or sprinkles. Temperatures throughout the weekend will be mild with highs just above freezing at plus 2 or 3C and lows near 0 or -1C. This same storm will intensify and bring the winter weary Maritimes more snow and strong winds on Sunday. Taking a quick look at the rest of March, it appears temperatures will remain below normal for Montreal with the likelihood of more snow.

Of note on this day in 1993, a massive storm hammered the east coast from Florida to Quebec. Take a look at it HERE.
