Showers and thunderstorms developed well ahead of an approaching cold front during the afternoon of May 26, 2021. Discrete storms developed over the central mountains, likely aided by a lee-side trough, and these cells eventually congealed into a line that crossed the Lower Susquehanna Valley. Well behind this line, another line of storms formed just ahead of the approaching front. Wind damage was the primary weather hazard throughout this event.
