Winter Weather in Lancaster, Pennsylvania

Snow fell across Lancaster County from the afternoon of December 13 through the afternoon of December 14. Most of the county saw 3 to 5 inches of snow with localized amounts as high as 7 inches.

Surface low pressure stationed across northern Ontario and western Quebec allowed for a cold frontal passage during the evening hours of December 13, 2025 across central Pennsylvania. Snowfall along and ahead of the cold front with ample moisture in place allowed for a brief period of light to moderate snowfall across the Laurel Highlands into the early morning hours of December 14th. After the cold frontal passage, enhanced westerly flow allowed for continued upslope snow showers across portions of Cambria and Somerset counties that brought additional accumulations into the evening hours of December 14th. Increased moisture off of the Chesapeake Bay allowed for an additional area of heavy snowfall to form across portions of York and Lancaster counties.
