Snowstorm Targets Northeast; Wintry Mix for NYC, DC

A storm Sunday into Monday will hit areas of the coastal Northeast largely missed by Friday's snow and ice. The storm threatens to bring travel delays and potential power outages to millions.
Travel delays and slippery conditions are likely Sunday over much of Virginia to southern Pennsylvania. Over much of upstate New York and interior New England, the storm and slippery travel will occur on Monday.
The storm has the potential to bring first accumulating snow of the season so far from Washington, D.C. to Philadelphia and New York City.
As the storm moves along Sunday through Monday, the risk of downed trees and power lines will tag along over the mountains and valleys of the central and northern Appalachians, due to wet snow and/or an icy mix with temperatures near the freezing mark.

People attempting to catch Sunday afternoon and evening flights in or out of the mid-Atlantic are likely to experience delays and could be faced with a few cancellations. These flight disruptions would expand into New England Monday.
Road conditions are likely to improve from Washington, D.C., to New York City by Monday morning as rain takes over, but travel may be slow, slushy and slippery around Boston in the early hours. Flight delays due to rain and low ceilings may linger through much of the day Monday in the I-95 Northeast.
Fresh cold air will invade New England and the mid-Atlantic in the wake of Friday night's storm delivering rain and some sleet and snow on its northwestern flank. The late Friday night storm may bring Boston its first accumulating snow of the season.

While the cold air is forecast to leave as the next storm is moving in Sunday and Monday, temperatures will not quickly rise above freezing everywhere.
According to AccuWeather.com Expert Senior Meteorologist Bernie Rayno, "In the mid-Atlantic, where the precipitation comes right in Sunday morning and midday and comes down hard, these areas will have the greatest chance of an extended period of slippery travel."
This is most most likely in parts of Virginia, Maryland and West Virginia and would include Roanoke, Va.; Washington, D.C.; Baltimore; and Martinsburg, W.Va. Temperatures are forecast to drop to or below freezing ahead of the storm Saturday night in these areas.

A brief period of snow and wintry mix is forecast around Philadelphia, but it could last long enough to bring slippery roads for a time Sunday afternoon.
The storm is forecast to start later in the day Sunday or Sunday evening farther to the northeast around New York City. This should allow temperatures to recover. However, at the very least part of the New York metro area will have some slippery travel for a time.
The northern and western suburbs of the I-95 cities will stay colder longer and are likely to have more snow, ice and travel woes when compared to the major cities closer to the coast.
Similar to parts of Virginia, portions of interior New England may be in for an extended period of snow and/or wintry mix later Sunday night into Monday. These areas will not get as warm Sunday and may cool ahead of the storm Sunday evening.
