 An embedded supercell in a quasi-linear feature produced a 
 tornado near Oxford, PA. A path of damage began in crop land near 
 the intersection of 5th Street and Waterway Road. Tree damage 
 continued northeast of here. 
 
 Significant damage occurred in the Wiltshire Development. On Slate
 Hill Drive, one house lost a southeast facing exterior wall. 
 Another house lost a significant amount of siding and a portion 
 of the roof. Tree damage continued in a northeast path. At Hickory
 Hill Road, there was damage to the roof of a commercial 
 outbuilding and a recreational trailer was flipped on its side.
 
 Sporadic tree and crop damage was noted from drone footage (this 
 portion of the path was inaccessible by vehicle) continuing to the
 northeast. A metal storage building at a business along Reedville
 Road had wall and roof damage. Further northeast there was damage
 to turkey pens near the intersection of Baltimore Pike and West 
 Branch Road.
 
 Additional tree and power pole damage continued in a northeast 
 path. The last damage noted along this continuous path was 
 exterior wall damage to a farm outbuilding and crop damage along 
 Street Road near Route 10. Sporadic tree damage was observed near 
 Route 10 and Ewing Road, but this does not appear to be in a 
 continuous path from the other damage, so this may have been 
 caused by straight line winds.
 
 The National Weather Service would like to thank Mr. Lou Ruh for 
 his assistance with this survey.

2.37 at PHL seems really low. I bet most of the city saw much higher amounts. Agnes, didn't you finish with 5"+?

Most of the precipitation was to the north and west of downtown (I am like 20 miles from the airport as the crow flies and was probably around the southern fringe of the heavy rain).  The southern parts of the city had less, which for people like those in Eastwick (in SW Philly), which continually gets flooded with this type of event, was spared this time (usually getting swamped by the Darby Creek and Cobbs Creek)!  They got walloped last year by Isaias. The neighborhood is adjacent to the airport.

 

Hilly areas south of me - like East Falls and Manyunk, got hit with flooding from the Schuylkill as they are situated alongside the river or at the bottom of the hills coming out of Roxborough and got the brunt of the river and runoff of water down the hills.

As a side note, when I was just looking for something else, I did stumble on this compiled from Mt. Holly data regarding TORWs over the past 25 years or so (so throwing in this thread just for FYI) -

By chance, could we sticky this thread to the top? What happened was historic, and it's an interesting read through the whole way.

I was driving east on 322 in South Jersey today, and not being familiar with the area didn't realize we were getting near Mullica Hill. The damage to the trees and houses told the story pretty quickly. It was something to see.

I went through Horsham and especially Ambler (near Temple Ambler) and it was a mess after a tornado(9/1). Trees/roofs torn, cars scattered randomly and a SUV on it's roof where it shouldn't be...
