Discussion
Low pressure is organizing over the northern Gulf coast this morning and it will then head in an east-northeast direction reaching the waters off the Carolina coastline by early tomorrow morning. From there, the low pressure system will continue on an east-northeast track on Thursday and undergo rapid intensification while out over the open waters of the western Atlantic Ocean. The DC metro region will be on the northern edge of this “southern stream” system today with some snow or snow shower activity likely during the afternoon hours. Small accumulations of a coating to an inch or so are likely; especially, in southern areas of the metro region…watch for slippery spots.
On Thursday, a vigorous wave of energy in the “northern stream” will pass right overhead of the Mid-Atlantic region and this will enhance upward motion and produce quite unstable conditions. As a result, there is likely to be additional snow or snow shower activity in the DC metro region on Thursday and small accumulations of a coating to an inch or so are again possible. On the heels of the low pressure, another windy and very cold day is coming to the Mid-Atlantic region on Friday, but temperatures should modify by the latter part of the weekend and the early part of next week.
