Winter Weather in Southern Centre, Pennsylvania

SNOW SQUALL. A snow squall impacted Southern Centre County early in the evening on December 19, 2025. A multi vehicle crash occurred on the southbound side of Interstate 99 near exit 61. Webcams showed heavy snow falling and accumulating on the roadway.

A strong area of low pressure stationed across northern Ontario allowed for a potent cold front to cross central Pennsylvania during the early morning hours of December 19, 2025. A strong line of gusty showers along the front caused multiple instances of measured wind gusts exceeding 58 mph in Clearfield, Dauphin, and Lancaster counties throughout the morning and afternoon hours. This line of gust showers also produced widespread tree damage in York and Lebanon counties during the afternoon hours, with no injuries reported. In the wake of the cold front, northwesterly flow allowed for a brief period of lake effect snow squalls, impacting portions of Interstate 99 and US Route 22 as the area of low pressure raced northeast.
