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 and undergo rapid intensification while out over the open waters of the western Atlantic. At the same time low pressure is intensifying rapidly off the coast on Thursday, a vigorous wave of energy in the northern jet 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 some snow or snow shower activity in the Philly metro region on Thursday and small accumulations of a coating to an inch or so are 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.
