1:40 PM | Mid-week Mid-Atlantic storm threat continues perhaps centering on the DC metro region

A major storm is headed towards the Mid-Atlantic region for Wednesday and, while light-to-moderate snow accumulations are possible across southeastern Pennsylvania, perhaps the greatest chance for significant snow is in the DC metro region. Low pressure will drop southeastward on Monday across the Northern Plains and it should reach the North Carolina/Virginia border region by later Wednesday. Significant total precipitation amounts are likely from West Virginia eastward across DC to the Delmarva Peninsula region and possibly as far north as the Pennsylvania Turnpike with lesser total precipitation amounts likely from NYC to Boston. As far as accumulating snow is concerned, it currently appears that the greatest chance for substantial snowfall will be across eastern West Virginia, western Virginia, western Maryland, and perhaps in the western suburbs of the District. Temperatures will be border line between rain and snow during part of the storm in the DC to Philly corridor so this will likely not be an all-snow event in those two metro regions. There is still a decent amount of time before the event unfolds on Wednesday and a small shift in the storm track can result in big differences. The storm pulls away on Thursday and high pressure takes over at the end of the week. Stay tuned.
