Heavy Rain, Interior Snow Follow Icy Sunday Travel in Northeast

After an icy start to Sunday in part of the Northeast, heavy rain and a swath of snow will continue to cause travel disruptions to finish up the weekend.
Several hours of freezing rain will glaze roads, sidewalks and elevated surfaces in part of northern New England, before temperatures rise above freezing Sunday night.
Despite subfreezing high temperatures throughout most of the Northeast on Saturday, the I-95 corridor is not facing a disruptive snowstorm.
While the rain has moved into New England, residents of central and eastern Pennsylvania, and the western suburbs of the I-95 corridor, should be on alert for black ice on roadways and sidewalks Sunday night.

The rain will be heavy at times and will also lead to travel disruptions from the Delmarva Peninsula to southern and eastern New England.
The steadiest rain around Foxboro, Massachusetts, is likely to come during the AFC Championship game.
"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," Sosnowski said.
Areas from New York City, Boston and Portland, Maine could experience problems due to urban flooding.
The heavy rain ended from southwest to northeast over much of the coastal mid-Atlantic during Sunday afternoon. The worst conditions will focus over New England Sunday night.
Localized flash flooding issues may also arise due to the frozen ground having trouble absorbing the rain. Melting snow in northern New England will expand the flooding threat.
"Temperatures could rise enough, combined with heavy rain to bring the risk of ice jam flooding along small streams and some rivers," Sosnowski said.
Thunder and lightning can accompany the heavy rain in some areas along the mid-Atlantic and New England coasts.

It is not until late 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 slow 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. Flooding problems due to runoff may continue in Maine for a time on Monday.
The winds will hold AccuWeather.com 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 on Monday.
