Modest instability and significant shear combined to produce a round of severe weather across western and portions of central Pennsylvania during the afternoon of May 30, 2017. Storms initiated shortly after midday along and just west of the Allegheny Front, and quickly evolved into discrete supercells. Low clouds and easterly flow over the middle and lower Susquehanna Valley prevented the storms from surviving as they progressed eastward into the more stable airmass.
