Discussion

As surface low pressure intensifies today out over the western Atlantic, a northern stream wave of energy in the upper part of the atmosphere will pass directly over the Mid-Atlantic region and this will enhance upward motion and produce quite unstable conditions. As a result, there is likely to be some snow or snow shower activity in the DC-to-Philly-to-NYC corridor and small accumulations of a coating to an inch or so are possible…watch out for slippery spots. On the backside of the departing strong low pressure, another very cold and windy (gusts to 40 mph) day is in store for the Mid-Atlantic region with well below-normal temperatures on Friday and even lower wind chill values.
