The Gulf Coast storm system will move northeastward today. Upper level energy Moisture is already streaming north, mainly as rain, over southeastern states. A cold front dropping in from the Great Lakes will merge with this coastal low and will create snow on the western flank of the storm system. Locally, some light wintry weather is possible for a while this morning, especially west of D.C. Most of the precipitation will change over to all rain after noon, as the moisture starts to pick up in coverage and intensity. The heaviest rain will fall overnight, as winds start to pick up. Wednesday will be rainy, windy, and cold. Total rainfall accumulations may range between two and four inches! Localized flooding is a concern in our region.
As the low races north, into New England, precipitation may end as snow late in the evening. Little to no accumulation is expected, as this time. Thanksgiving Day brings much quieter weather to the Nation's Capital. It will remain cold, with highs Thursday in the upper 30s and still a bit breezy. We remain dry and chilly on Black Friday with highs, again, in the upper 30s. Traveling Saturday and Sunday should be much easier with partly cloudy skies both days and highs in the 40s.
