Snow Forecast To Impact Millions In The Northeast This Weekend, Including DC, Philadelphia, New York, Boston

A big blast of snow, then cold air is set to sweep across the Northeast this holiday weekend.

Named Winter Storm Demi by The Weather Channel, it will bring a quick round of snow to some of the country's largest cities, which could impact everything from travel to playoff football.

C​urrent Winter Weather Alerts

W​inter storm watches have been added from the northern Virgnias to the interior portions of southern New England. This is where snow may make roads tricky to navigate by later in the holiday weekend.

Saturday

On Saturday, a cold front will sweep through the area, bringing mainly rain to coastal areas and the Interstate 95 corridor. Some light snow will sweep through interior sections of the Northeast, northern New England and the Ohio Valley.

A soggy Saturday is expected across much of the Southeast.

However, this is not the main event.

Sunday

The headliner for this weekend’s system is the area of low pressure that will shoot out of the South and head north along the Atlantic coast. This will strengthen as it moves northward and wring out the snow across the Northeast and New England.

There are still model discrepancies as to how much snow will fall; much of this depends on how close to the coast the low tracks.

If the low hugs the coast, then there will be more snow for the big cities. But if the low tracks farther west, then the snowfall amounts will be smaller along I-95.

S​unday Night

Sunday evening, the snow will be wrapping up from south to north before eventually moving out by Monday morning. Much of the Northeast and New England will continue to see snowfall during the overnight hours.

H​ere's a look at snowfall totals expected from Winter Storm Demi.

The Rams vs. Eagles playoff game in Philadelphia on Sunday could get interesting. With the potential for snow moving in, there could be issues with travel getting to and from the game. Right now, the forecast calls for generally up to 5 inches of snow in and around Philadelphia, with the highest totals along I-95 and westward.

T​he rest of the Northeast and New England could see several inches of snow, but there are still uncertainties. Regardless, there will still be travel trouble Sunday evening into Monday morning, with slick roads and possible airport delays.

T​he mid-Atlantic, including Washington, D.C., is also forecast for snowy conditions much of Sunday. The forecast calls for a couple of inches of snow, but the snow will be pushing out well ahead of the Presidential Inauguration on Monday.

D​angerous Cold Settles In

While the snow wraps up on Sunday, the winds will kick in Sunday night into Monday. Any snow on the ground will have the potential to blow around and cause visibility issues, making travel difficult in some areas.

Once the snow moves out, the coldest air mass of the season will move in, lasting through much of next week. Some areas will experience dangerously cold temperatures. Places like Boston could see morning wind chills dip to minus 10 to 15 degrees for multiple mornings in a row.
