Getting some heavy downpours from the southern edge of the complex skirting the Pa line. Some thunder in the distance 

Are you seeing a low level dust cloud kicked up as the heavy rain falls? :D

A snippet from the updated AFD from Mt Holly-

Hot and humid into the early evening hours ahead of an approaching shortwave. Showers and thunderstorms over central Pennsylvania will continue to track east, and additional storms will fire up ahead of that main area. Temperatures remain in the 80s to around 90 with surface dewpoints in the upper 60s to low 70s. As a result, surface-based CAPE values are up around 2000 J/kg across Delmarva and from 1500-2000 J/kg across southern New Jersey and southeast Pennsylvania. Across Delmarva and southern New Jersey, DCAPE values are up around 1000 J/kg. 0-6 KM Bulk Shear is minimal, generally around 25 kt, but up to 40 kt across far northern New Jersey. Finally, PWATs are from 1.5- 2.0 inches. Thunderstorms moving into the unstable airmass, especially across the southern half of the forecast area, will become strong to severe, with damaging winds and heavy rain the most likely impacts.

Hrrr has action all through to well after midnight :raining::lightning:

 

   With radar showing a lot of activity forming over WV, indicative of strong forcing that will overspread our area over the next few hours, the scenario of multiple rounds certainly seems plausible.
