Strong Wind in Dauphin, Pennsylvania

Wind gusts between 40 and 50 mph throughout the afternoon of December 19 knocked down several trees and power lines across Dauphin County.

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.
