Nor’easter to Bring First Snow of the Season to the Northeast, Disrupting the Busy Interstate 95 Corridor
The first Nor’easter of the winter season is expected to move out of the Southeast and up along the East Coast late Monday night through Wednesday, bringing a mix of rain, ice, and snow to the region. 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, with Winter Storm Watches posted for parts of central and upstate New York, western Massachusetts, southern Vermont, southern New Hampshire, and Southern Maine.
Impact on Travel and Daily Life
A fast-moving area of low pressure will move out of the Southeast and up along the East Coast late beginning Monday night through Wednesday. According to the Fox Forecast Center, some computer forecast models are drawing an extremely sharp boundary between rain and snow, which is currently expected to set up just inland of I-95. New Jersey Governor Phil Murphy declared a State of Emergency beginning at 5:00 A.M. ET on Tuesday due to the significant impacts expected from the storm.
Temperatures will likely be too warm for snow along the coast, but periods of heavy rain Tuesday could cause travel delays at airports in Washington, D.C., Philadelphia, Newark, New Jersey, New York City, and Boston.

Expected Snowfall and Ice Accumulation
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.

Meanwhile, where exactly the rain-snow line sets up could have significant impacts on drivers. Anywhere between a coating and 0.25 of an inch of ice is forecast for roads in the Appalachians, particularly in West Virginia and Virginia. Higher elevations in Pennsylvania, northern New Jersey, New York’s Mid-Hudson Valley, and Connecticut could also see ice accumulating.

La Niña Pattern and Future Weather Outlook
The presence of a La Niña pattern historically tends to bring more frequent nor’easters along the Eastern Seaboard, which saw several coastal storms this past fall. NOAA indicated that the U.S. may shift back to neutral conditions around the start of January. 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.
