The episode as NWS PHI wrote it up.
A southward moving cold front stalled across northern New Jersey and northeast Pennsylvania early on September 13. Warm and humid conditions were present south of the front. An upper level disturbance moving through the westerly flow aloft helped to increase wind shear. Combined with the instability, this disturbance caused a line of thunderstorms to move through the region during the evening hours of September 13. This line of storms became severe, with a number of reports of damaging wind along it. The line moved offshore and out of the region later that evening.

NWS Philadelphia/Mount Holly wrote its last area forecast discussion before the first event at Sep 13, 7:04 PM EST, 28 minutes earlier.
Area Forecast Discussion National Weather Service Mount Holly NJ 804 PM EDT Mon Sep 13 2021 .SYNOPSIS... A cold front will slowly move south tonight before moving pushing back north as a warm front on Tuesday. Another cold front will approach the region on Wednesday, stalling nearby through Thursday. A coastal low pressure may bring some unsettled weather to the region Friday into Saturday. High pressure will slide across the northeast on Sunday. && .NEAR TERM /THROUGH TUESDAY/... Cold front remains draped across northern Pennsylvania and northern New Jersey. A cluster of thunderstorms that produced heavy rain and locally damaging winds is tracking through northeast Pennsylvania, and is approaching Carbon and Monroe counties, and should pass through the Lehigh Valley going through this evening. While SB CAPE values range from 1500-2000 J/kg, there is an area of CIN over much of the region. DCAPE values are on the order of 700-900 J/kg. There is a good deal of wind shear, though, ranging from 40-50 kt. Severe Thunderstorm Watch 497 now in effect until 1 am for parts of northern New Jersey and portions of the Lehigh Valley and southern Poconos. Any convection should wind down by the predawn hours. some patchy fog is possible. Conditions on Tuesday should turn out to be fairly nice overall. However, with the boundary pushing north as a warm front, the area remains in the warm sector. With highs rising back into the 80s and dew points back into the 60s to around 70, it will feel muggy and very much like summer outside. A chance for diurnally driven showers or thunderstorms will be possible, mainly across the southern Poconos and Lehigh Valley during the afternoon and evening hours. && .SHORT TERM /TUESDAY NIGHT THROUGH THURSDAY NIGHT/... Any showers and thunderstorms that develop across the Lehigh Valley and areas to the north and west should dissipate as we head past sunset Tuesday night. Skies may continue to have some clouds around but most areas should see some clearing overnight. The next cold front approaches the region on Wednesday. We should be dry through much of the day but some showers and thunderstorms may start to develop by early afternoon across our northwestern areas before starting to spread to the south and east as a cold front drops into the region. The front may not make it more than halfway through before it stalls, leaving us unsettled through at least Thursday. The heat and humidity will persist across the region for Wednesday and Thursday, especially for areas to the south of the stalled boundary. && .LONG TERM /FRIDAY THROUGH MONDAY/... As we head into the end of the week, we turn our eyes to the potential coastal system, which looks to remain largely offshore. However, some models take it closer to the coast so we can't fully discount that there may be some showers that move into the area on the east to northeast flow. This flow should help to keep us more stable so expect it will remain more showery than thundery as we move through Friday and Saturday, with the low pushing off to our northeast Saturday afternoon/evening. Behind the system we see high pressure take control land move over the northeast states. The high hangs around into early next week. && .AVIATION /00Z TUESDAY THROUGH SATURDAY/... The following discussion is for KPHL, KPNE, KTTN, KABE, KRDG, KILG, KMIV, KACY and surrounding areas. Tonight...Overall, a VFR forecast. Some SHRA/TSRA may affect KRDG/KABE and possibly KTTN, but will only include a VCTS for KABE due to low confidence in a storm passing over a given terminal. Some patchy fog possible late tonight. LGT/VRB winds. Moderate confidence. Tuesday...VFR. LGT/VRB winds becoming SW, then S at 5-10 kt. Slight chance of some scattered storms forming in the afternoon near KRDG/KABE but low confidence on this. Moderate confidence on the overall pattern, but low confidence on the timing and coverage of showers and storms. Outlook... Wednesday...Mainly VFR becoming MVFR or lower in showers and thunderstorms Wednesday afternoon and night. South to southwest winds around 10 knots becoming light at night. Moderate confidence. Thursday...Mainly MVFR with lower conditions possible in showers and thunderstorms. East to southeast winds around 5 to 10 knots becoming light at night. Low confidence. Friday through Saturday...Mainly VFR though MVFR possible at times in showers. East-northeast winds around 5 to 10 knots on Friday becoming light north to northeast winds on Saturday. Moderate confidence. && .MARINE... Sub-SCA conditions will continue on the area waters through Tuesday. Seas around 2 feet. South-southwest winds will become easterly on Tuesday. Outlook... Wednesday...Winds may gust around 25 knots on the ocean waters and a SCA may be needed for the afternoon and evening hours. Seas may near 5 feet on the northern New Jersey waters. Thursday...Seas and winds are expected to remain below SCA criteria. Friday...Seas may approach 5 feet on Friday as a coastal low passes to the east of the ocean waters. Saturday...Seas and winds are expected to remain below SCA criteria. Rip Currents... Lighter winds combined with less of a long period swell component and lower waves in the surf zone results in a LOW risk of dangerous rip currents for both the New Jersey and Delaware beaches for today. Southeasterly winds are expected to increase, however waves in the surf zone are forecast to be low along with a lower swell component and therefore a continued LOW risk of dangerous rip currents will continue for Tuesday. && .PHI WATCHES/WARNINGS/ADVISORIES...
