A disturbance diving towards the Delaware Coast by this evening will bring periods of snow showers and some light snow in time for the evening rush hour. While snow fall accumulations will be light, the impacts will be an issue for the evening commute.
Clouds will steadily increase through the day with winds from the north and northwest at 5 to 15 mph. Cold conditions will continue with temperatures struggling in the upper 10's to lower 20's for highs throughout the Philadelphia and New York City metropolitan areas. The combination of the northerly winds with the cold temperatures will produce wind chills in the single digits and lower 10's which can cause frost bite in a short period of time.
This evening, snow showers will become widespread throughout the Philadelphia and New York City metropolitan areas. The snow will become steady and light to moderate over southern Pennsylvania, southern and central New Jersey, and southeastern Long Island leading to snowfall totals as much as three inches. For locations north and northwest of the Philadelphia and New York City metropolitan areas, the snow showers will become more scattered in nature and thus more likely to only have a trace in most locations.

Temperatures will fall into the single digits to mid 10's for lows tonight.
