Event narrative

SNOW SQUALL. A snow squall impacted Interstate 80 in Clearfield County during the afternoon of January 29, 2025. An RWIS station at Exit 111 on Interstate 80 near Penfield reported a visibility drop to below 1/4 mile as the squall moved through and a wind gust of 25 mph. The same squall produced a wind gust of 40 mph at the Clearfield-Lawrence Airport as well as a visibility drop to below 1/4 mile in heavy snow.

Wider weather episode

During the early morning hours of January 29, 2025, a potent Arctic Front began dropping southeast into Pennsylvania and became collocated with the left exit region of a strong upper-level jet. These factors, coupled with marginal surface-based instability, allowed for heavier snow showers and snow squalls to form by mid-morning. Dynamics and sufficient lift were most favorable in the northern half of the Commonwealth, thus snow squall potential dropped fairly rapidly south of the Interstate 80 corridor. Multiple snow squalls were observed; however, no injuries and/or fatalities were observed due to traffic accidents in snow squalls. Gusty winds ahead of the cold frontal passage knocked over multiple trees into wires in Perry County, closing West Main Street for a period of time.
