Wider weather episode

Low pressure passed through the area while high pressure to the north supplied cold air. The heaviest snow occurred over northern Maryland, just north from the surface low. Snowfall averaged between 4 to 8 inches for most of these areas. Snowfall averaged around 1 to 3 inches across central Maryland, with less over southern Maryland toward Washington DC.

There was also a light glaze of ice in the Allegheny Highlands as warmer air worked its way in aloft allowing the snow to end as a period of light freezing rain and freezing drizzle.
