A slowly southward-moving front was draped across central Ohio and Pennsylvania on July 13th.  Warm air aloft initially kept storm development muted, but a mesoscaled convective vortex fired thunderstorms by early to mid-afternoon over the Middle Ohio Valley.  These storms lifted northeastward into an environment characterized by 40 to 50 knots of deep-layer shear and up to 2500 J/kg of mixed layer CAPE.  Dry air aloft also enhanced the downburst wind threat.  As a result, many reports of tree damage were received across southwest Pennsylvania, along with several instances of marginally severe hail.
