The first Nor’easter of the winter season will move out of the Southeast and up along the East Coast late Monday night through Wednesday. The heavily populated Interstate 95 corridor will likely see mostly rain, with ice forecast for the Appalachians and higher elevations in Pennsylvania and northern New Jersey. The heaviest snow will fall across the interior Northeast. Winter Storm Watch has been posted for parts of central and upstate New York, western Massachusetts, southern Vermont, southern New Hampshire and Southern Maine.

Heavy snow is forecast for the interior Northeast, as the storm taps into some of the coldest arctic air of the season that will set up over the region.
Winter Storm Watches have been posted for parts of central and upstate New York, western Massachusetts, southern Vermont, southern New Hampshire and southern Maine beginning Monday night.
WINTER STORM WARNING EXPLAINED
Winter Storm Alerts are in effect from the Ohio Valley to Maine, which will see between 3-5 inches of snow, while 5-8 inches are expected across upstate New York and interior New England.
The effects of the snow will be amplified across higher elevations, including parts of the Adirondacks, Green and White mountain ranges through Wednesday morning.

Another round of even colder arctic air is expected to reach the East Coast by Thursday, which could create slick roads during the morning rush.
