A disturbance moving along a stalling cold front this evening will bring the threat for a few widely scattered to isolated showers over portions of northeastern Pennsylvania and northwestern New Jersey tonight.
There is a lot of dry air in place over the Philadelphia and New York City metropolitan areas, which is prevent much of this precipitation from reaching the ground. However, as the afternoon and evening progresses, some of the precipitation will reach the ground in the form of snow flurries, sleet, and freezing drizzle. The best potential for this will be over northwestern New Jersey and northeastern Pennsylvania where lifting will be strongest overnight. While the precipitation is not expected to be heavy, only a trace of ice is needed to create hazardous road conditions overnight. At this time, less than an inch of snow and less than a tenth of an inch of ice is expected from this disturbance. A Winter Weather Advisory has been issued for the northern portion of the Delaware River and surrounding counties.
The rest of the northern Mid Atlantic can expect overcast skies and an occasional flurry or drizzle through tomorrow morning.
