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 later today; especially, during bursts of heavier snow. 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.
