Wider weather episode

Low pressure developed over the southeastern CONUS while high pressure to the north supplied cold air to start. Precipitation started as snow, but warmer air worked its way in from the Atlantic, causing precipitation to change to ice and even rain across portions of central and eastern Maryland. Snow on the back side of the system impacted the Allegheny Highlands through the 17th. Snowfall amounts ranged from around 1 to 3 inches near and east of Interstate 95 with 2 to 4 inches west of Interstate 95 to the Catoctin Mountains.
