Warnings Issued

More heavy snow is forecast for the northeast into New England and southern Quebec. Above is a photo from the Salem County News in New Jersey.
They are expecting the third major storm this month.

11:30 am UPDATE: Warnings Extended into our region: Low pressure continues to move north into New England at 11:30am. Heavy snow is now falling in Montreal and warnings have been extended into the Ottawa Valley, Lachute and areas west and north of the city. Heavy Snow Warnings have also been posted for the 401 corridor from the Quebec Border to Prescott, Ontario and north to Highway 43. The snow will accumulate from 15-25cm today. Visibility is low and roads are snow packed and icy. The snow is very heavy and wet. More details later today.

As expected wet snow developed overnight across the region as low pressure moved into southern New England. The snow was the heaviest from Albany into the Catskills north into southern Vermont and the Green Mountains and into the eastern Townships. This morning travel is not recommended on Highway 10 east of Montreal towards Sherbrooke and south along Interstate 89. The snow has accumulated over 15cm with as much as 30cm reported. The heavy wet snow has brought down power lines, and dozens of schools are closed in Vermont and New York. There are reports of tractor trailers stuck on hills along the Eastern Townships Autoroute. Here in Montreal the snow has been much lighter, but roads are icy and snow packed and travel is slow. Around 5cm fell overnight with another 10cm or so expected today. The snow is very elevation dependent and very localized. Even on the Island of Montreal some places are reporting rain while not too far away it is snowing (L'Ile Perrot vs Dorval for example). Winter Storm Warnings remain in effect for Vermont, northern New York, the Townships and Laurentians through tonight.

Our attention will then turn to the next storm developing across the southern plain states. This system will follow a similar path up into southern New England. Heavy snow will fall along and to the west of the storm track from New Jersey and Delaware north into New York and Vermont. Winds will be very strong with this next storm and warnings may be needed. We will clear this storm out of the way today and then deal with the next system. Expect more rain and snow with strong winds to move into Montreal and southern Quebec by late Thursday. Amounts will be difficult to forecast with plenty of warm air arriving with the storm.
