Low pressure passed by to the west as it tracked into the Ohio Valley and Great Lakes on the 18th into the morning of the 19th, before transferring its energy to a coastal low along the Mid-Atlantic Coast. The coastal low moved out to sea later on the 19th.
Canadian high pressure supplied plenty of low-level cold air, but warmer air worked its way in aloft, and this caused a wintry mix of snow, sleet, and freezing rain. Snow and sleet overspread the area on the early morning of the 18th. Snow and sleet changed to a light wintry mix including freezing rain by the evening of the 18th. Precipitation ended as a period of light snow and sleet on the morning of the 19th.
The highest snowfall accumulations were across the eastern Panhandle of West Virginia toward the Potomac Highlands (around 4 to 8 inches of snow) where the heaviest precipitation occurred while temperatures will still cold enough for snow.
Ice accumulation from freezing rain was up to a tenth of an inch for most areas, mostly on the evening of the 18th into the overnight.
