Winter Weather in Union, Pennsylvania

Snowfall began in Union County during the early morning hours with the heaviest snowfall falling during the evening hours of February 22nd and into the morning hours of February 23rd. Snowfall amounts in the county ranged generally between from two to four inches; however, a heavy snow band across western portions of the county allowed for localized accumulations between six and seven inches. Snowfall became lighter during the late morning hours of February 23rd before tapering off during the afternoon/evening hours. No incidents were reported due to this snowfall.

A coastal low stationed off the Tidewater of Virginia during the morning to afternoon hours of February 22, 2026 allowed for ample moisture influx from the Atlantic with light snow forming across portions of eastern Pennsylvania. Light snow was mainly observed throughout the morning and afternoon hours with heavier snow beginning during the late evening hours and throughout the morning hours of February 23rd across portions of eastern Pennsylvania. This heavier snow was due to a combination of bombogenesis of the aforementioned area of low pressure and ample frontogenetic forcing that allowed for a heavy band of snowfall to form across portions of south-central Pennsylvania extending into the Susquehanna Valley. Winds associated with the pressure gradient of the rapidly deepening cyclone allowed for gusty winds, generally in the 30 to 40 mph range, across much of eastern Pennsylvania with highest gusts closer to the Atlantic Coast. Slick conditions and gusty winds from this system allowed for multiple accidents across eastern Pennsylvania, including one that resulted in one injury in Lancaster County.
