Snow and freezing rain

AccuWeather.com

The forecast seems on track this morning as twin low pressure areas one along the east coast of the US and the other over the Ohio Valley begin to influence our weather. Light snow is spreading north into Montreal at 7am with a mix of snow and freezing rain in the 401 corridor to Kingston and rain southwest of there. Heavier snow is showing on radar south of the border along I-87 between Albany and Plattsburgh and moving north. Snow will mix with sleet and could be steady at times in southern Quebec today with accumulations of 5-10cm. Winds will be gusty out of the northeast at 30 to 50km/h. Winds are already gusting up to 40km/h at Trudeau Airport. Precipitation will taper off this evening to light freezing drizzle as the first storm system lifts northeast into Atlantic Canada. A wedge of warmer air will push temperatures up to 0C overnight in Montreal but they will begin to fall rapidly on Friday to the coldest readings this winter by Sunday morning, around -20C.

Meanwhile the main low pressure center over the Great Lakes will moves east overnight and across southern Quebec and New England on Friday. It will bring strong winds and falling temperatures with a mix of rain and snow. When all is said and done between the two systems it looks like 15cm of snow will have fallen in Montreal and Ottawa along with some liquid precipitation in the form of freezing rain or rain across extreme southern Quebec. It will be clear and cold for the weekend into Monday before another storm brings us a chance of snow on Tuesday.
