A warm front lifted northeast across Pennsylvania, just ahead of a line of convection. Dewpoints in the mid 60s to near 70 spread eastward with time and increased in coverage. Strong heating and destabilization occurred in strong deep layer west/southwestly flow. Low-level lapse rates steepened, and 30-40 knot southwest winds around 700mb increased support for damaging thunderstorm wind gusts. Vertical shear supported rotating updrafts and a few supercell structures.
