The episode as NWS PBZ wrote it up.
A large area of strong low pressure tracked up the eastern seaboard downstream of a digging positive to neutrally tilted trough. Deep moisture through the dendritic growth zone and strong forcing resulted in widespread significant snowfall accumulation greater than 6 across the entire county warning area with amounts generally falling between 10-18. Localized amounts under narrow frontogenetically-forced bands reached up to 22 inches. An intruding mid-level warm nose reduced snow amounts slightly in northern West Virginia and resulted in a period of some mixing of snow with freezing rain and sleet.
