What happened
The episode as NWS PHI wrote it up.
Around two inches of rain fell within one hour near Hamilton Square in southwest Mercer County. This caused the flash flooding of smaller streams in the area as well as urban and poor drainage flooding. Fortunately this heavy rain fell just to the south of the torrential downpours from the previous evening and did not exacerbate the ongoing problems in those areas. No serious injuries or damage was reported.
The radar
The Philadelphia radar (KDIX), 45 km away, was scanning. The volume nearest the first event began at 20:01 UTC.
