I-95 Rain, Interior New England Snow to End Weekend

The Northeast will be dealing with a soaking rain, a swath of snow and another round of brisk winds Sunday through Monday.

Despite subfreezing high temperatures throughout most of the Northeast on Saturday, the I-95 corridor is not facing a disruptive snowstorm.

Instead, a quick surge of warmth ahead of a storm riding up the coast will cause rain to spread northward from the eastern Carolinas to Washington, D.C., to New York City to Portland, Maine, on Sunday through Sunday night.

The steadiest rain around Foxboro, Massachusetts, is likely to come during the AFC Championship game.

As the rain begins, there is concern for a period of icing from Harrisburg, Pennsylvania, to the northern and western suburbs of Philadelphia to northwestern New Jersey and the southern Hudson Valley on Sunday morning.

"The rain may sneak in a few hours before temperatures nose above freezing, so some untreated roads or sidewalks could become slick," according to Meteorologist Bill Deger.

This danger includes Allentown, Pennsylvania, and Poughkeepsie, New York.

Plain rain alone could cause disruptions to travelers.

According to Senior Meteorologist Alex Sosnowski, "People hitting the roadways should be prepared for rainy travel with poor visibility. Airline delays are also possible as well due to low visibility and low cloud ceilings."

Due to the frozen ground having trouble absorbing the rain, localized flash flooding issues may also arise.

It is not until Sunday night as the storm moves through New England that colder air will arrive, causing the storm to strengthen and snow to develop along its northwestern fringe.

The cold will come via another, yet weaker storm system that will spend Sunday delivering snow showers, mixed with rain showers over eastern areas, to the Great Lakes and central Appalachians.

The heaviest snow will develop across Vermont and upstate New York to the western and central St. Lawrence Valley. Such snow will create treacherous travel conditions, while providing fresh powder for ski resorts.

Motorists planning to drive on I-87, I-89, I-91 in northern New England should prepare for slower travel.

Snow mixing with or changing to rain for a time will hold down amounts in northern New Hampshire, northern Maine and northward to Quebec City, Ontario.

The storm will depart Maine and the St. Lawrence Valley on Monday, but brisk winds on its back side will chill all of the Northeast for Martin Luther King, Jr. Day.

The winds will hold RealFeel® temperatures generally to the 20s across the region. The exceptions will be the teens near the eastern Great Lakes and the 30s toward Washington, D.C.

In addition to the fresh chill, snow showers will continue to fly across the central and northern Appalachians.
