Event narrative

SNOW SQUALL. A snow squall impacted Potter County on the morning of January 29, 2025. An RWIS station on State Route 6 near Coudersport recorded a visibility drop to below 900 feet as the squall moved through. The camera at the station showed snow quickly accumulating on the roadway. A spotter located 5 miles north-northeast of Denton Hill State Park reported visibility below 100 yards as the same squall impacted their location. They also reported that 1 inch of snow fell with the squall.

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.
