East of the city, including Prince George’s, Anne Arundel and Charles counties, a winter weather advisory is in effect for 2 to 4 inches of snow Wednesday afternoon after a period of rain or mixed precipitation.

Southern Maryland is not included in any advisory or warning, as mostly rain is expected.

The warning, covering areas right along and west of I-95, is an expansion of a warning that covered areas further west issued early this morning. In those locations farther to the west, including Loudoun, Fauquier and Frederick counties, 8 to 14 inches of snow is forecast by the NWS.
