Blown Discharge

Heavy rain along the rear-flank downdraft of a supercell masked most of the mesocyclone region, but that didn't stop the scene from erupting in a beautiful blast of windbown lightning. It wa no coincidence that the discharge's shape seemed to follow the outrush of air. Precipitaiton loading helped the downdraft region to create severe winds, which in turn redirected the invisible, downward-propagating step leader away from the core before it could be set alight by the essentially instantaneous return-stroke surge.
