Event narrative

A severe thunderstorm producing winds estimated to have been 100-110 mph produced considerable straight-line wind damage between Mifflintown and Thompsontown. The strongest downburst winds associated with the storm occurred at the Centre Lutheran Church, where the roof of the church was peeled off from the north. A metal cross on the church's steeple was also destroyed, while a pine tree adjacent to the church had a piece of its trunk snapped off. The storm then continued

southeastward across the Juniata River, producing tree damage near the PFBC Vandyke Hatchery. Additional tree damage was then found farther southwest along Highway 333 immediately southeast of Mexico and east of Port Royal, associated with the rear flank

downdraft of the storm.

Wider weather episode

A north-south stationary boundary bisected central Pennsylvania ahead of a cold front approaching from the Great Lakes on June 16, 2022. A broken line of showers and thunderstorms formed along a lake-breeze front that developed over northwestern Pennsylvania, just ahead of the approaching cold front. As this line progressed southeastward, one of the cells within the line became a long-track supercell that produced a swath of wind damage and hail from Warren County southeastward to the Lower Susquehanna Valley.
