2:30 PM | *Significant snow on the way for the entire DC metro region*


The storm that will move into the Mid-Atlantic region on Wednesday is now causing accumulating snow across Wisconsin, Indiana and Illinois after dumping up to 18 inches across parts of North Dakota and a foot of snowfall in upstate Minnesota. Precipitation is likely to reach the DC metro region early tonight in the form of rain, snow or a mixture of the two. As the night progresses, colder air will cause a changeover of the precipitation to primarily snow by morning and there will then be periods of snow on Wednesday that will be heavy at times, maybe even some thundersnow. Total accumulations by later tomorrow evening should be in the 6-12 inch range with the higher amounts in that range to the west of the District. The “bullseye” region for snowfall amounts will likely end up being the higher elevation spots of eastern West Virginia, western Virginia and western Maryland where more than a foot of snow can accumulate. Meanwhile, farther north and east, Philly may get 3-6 inches of snow by late tomorrow night and the New York City metro region is likely to receive even less snowfall with accumulations of 1-3 inches possible there by Thursday morning. Stay tuned, March storms are often tricky.
