Light precipitation spread east across the Mid Atlantic ahead of a low pressure system. Temperatures at the onset of precipitation were cold enough to produce snow. As precipitation spread east of the Blue Ridge, temperatures aloft increased to above freezing while temperatures at the surface remained below freezing. This caused eastern portions of the state to see a change over from snow to freezing rain. Road conditions began to rapidly deteriorate during the afternoon rush when rain began to freezing onto the roadways. Numerous traffic accidents were reported across the Baltimore Metro and across the northern Washington DC suburbs.
Several inches of snow was reported in the western part of the state in Allegany and Washington counties, with a mix of snow, sleet and freezing rain in central Maryland. Mostly ice was reported further east into the Baltimore Metro and northern Washington DC suburbs.
