The combination of a cold frontal passage and an unseasonably hot and humid air mass generated a series of strong to locally severe thunderstorms that moved through New Jersey during the afternoon and evening of the 6th. The strongest thunderstorms affected central and northern New Jersey where about 37,000 homes and businesses lost power.

The episode as NWS PHI wrote it up.
The combination of a cold frontal passage and an unseasonably hot and humid air mass generated a series of strong to locally severe thunderstorms that moved through New Jersey during the afternoon and evening of the 6th. The strongest thunderstorms affected central and northern New Jersey where about 37,000 homes and businesses lost power. Most of the power was restored by midnight that night.

NWS Philadelphia/Mount Holly wrote its last area forecast discussion before the first event at Sep 6, 2:44 PM EST, 21 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE MOUNT HOLLY NJ 344 PM EDT SAT SEP 6 2014 .SYNOPSIS... A STRONG COLD FRONT APPROACHING FROM THE NORTHWEST WILL PASS THROUGH OUR REGION TONIGHT FOLLOWED BY HIGH PRESSURE FOR SUNDAY INTO MONDAY. LOW PRESSURE IS FORECAST TO DEVELOP ALONG THE MIDDLE ATLANTIC COAST ON MONDAY NIGHT AND TUESDAY BEFORE MOVING OUT TO SEA ON WEDNESDAY. A COLD FRONT IS EXPECTED TO APPROACH FROM THE NORTHWEST ON THURSDAY AND THURSDAY NIGHT AND IT SHOULD PASS THROUGH OUR REGION EARLY ON FRIDAY WITH ANOTHER AREA OF HIGH PRESSURE ARRIVING IN ITS WAKE. && .NEAR TERM /UNTIL 6 AM SUNDAY MORNING/... SHWRS AND TSTMS WILL BE WORKING THEIR WAY ACRS THE REGION AHEAD OF A CDFNT WHICH WILL MOVE THRU THE REGION TONIGHT. THE ENTIRE AREA HAS BEEN PLACED UNDER A SVR TSTM WATCH. THERE IS GOOD SHEAR, AND MOISTURE (WHICH IF ANY STEPS OUTSIDE YOU KNOW) WITH DEW PTS IN THE LWR 70S AND CAPE. HVY RAIN AND DAMAGING WIND LOOK TO BE THE MOST LIKELY HAZARDS. LATEST RADAR SHOWED INCREASING COVERAGE, MAINLY OVER NRN AND WRN AREAS, MOVING SLOWLY EWD. POPS WILL BE HIGHEST N AND W ERLY, AND SHIFT S AND EWD LATE. PRECIP CHCS WILL END N AND W AROUND MIDNIGHT AND IN ALL BUT THE EXTREME SRN AREAS BY DAYBREAK. BEHIND THE CDFNT, A NOTICEABLY COOLER AND MORE PLEASANT AMS IS IN STORE (MORE TYPICAL OF SEPTEMBER). && .SHORT TERM /6 AM SUNDAY MORNING THROUGH 6 PM SUNDAY/... FOR SUN, A REFRESHING CHANGE WILL BE NOTICED BY ALL, WITH LESS HUMIDITY, COOLER TEMPS AND DRY WX EXPERIENCED BY ALL. THERE COULD STILL BE SOME LINGERING SHWRS ERLY IN THE EXTREME S, BUT A GENLY DRY DAY IS ANTICIPATED. HIGH TEMPS WILL BE IN THE UPPER 70S LWR 80S, VS THE UPR 80S AND 90S LIKE WE HAVE BEEN. && .LONG TERM /SUNDAY NIGHT THROUGH SATURDAY/... SURFACE HIGH PRESSURE IS EXPECTED TO BUILD ACROSS THE SAINT LAWRENCE RIVER VALLEY AND NORTHERN NEW ENGLAND ON SUNDAY NIGHT. THE AIR MASS WILL LIKELY BRING DRY WEATHER CONDITIONS TO MOST OF OUR FORECAST AREA AT THAT TIME. HOWEVER, CLOUDS MAY BE ON THE INCREASE FROM THE SOUTH LATE ON SUNDAY NIGHT AND THERE IS A CHANCE OF RAIN IN SOUTHERN DELAWARE AND IN THE ADJACENT COUNTIES OF NORTHEASTERN MARYLAND TOWARD MONDAY MORNING OUT AHEAD OF OUR NEXT WEATHER SYSTEM. AN INVERTED SURFACE TROUGH IS FORECAST TO BE LOCATED ALONG THE SOUTHEAST COAST OF THE UNITED STATES ON MONDAY. MEANWHILE, A MID LEVEL SHORT WAVE TROUGH IS EXPECTED TO PASS ACROSS THE SOUTHEASTERN STATES AT THAT TIME. A SURFACE LOW IS ANTICIPATED TO DEVELOP ON THE INVERTED TROUGH ALONG THE NORTH CAROLINA COAST ON MONDAY NIGHT WITH ANOTHER LOW FORMING FARTHER OUT TO SEA BEYOND 70 WEST LONGITUDE. BOTH LOWS ARE FORECAST TO DRIFT OUT TO SEA. WHILE THE EASTERN LOW SHOULD NOT IMPACT OUR REGION, THE ONE CLOSE TO THE COAST WILL LIKELY HAVE SOME INFLUENCE ON OUR WEATHER. THERE IS STILL A BIT OF A SPREAD AMONG THE MODEL GUIDANCE. HOWEVER, THERE IS A GENERAL TREND OF SOME RAIN SPREADING INTO OUR REGION FROM THE OCEAN MAINLY FOR MONDAY INTO TUESDAY. THE GUIDANCE SEEMS TO SUGGEST A FAIRLY GOOD CHANCE FOR RAIN ON THE COASTAL PLAIN WITH A BIT MORE UNCERTAINTY FOR AREAS TO THE NORTHWEST. THE PRECIPITATION IS FORECAST TO MOVE OUR TO SEA ON TUESDAY NIGHT AND WEDNESDAY. AN ONSHORE FLOW FOR MONDAY, TUESDAY AND WEDNESDAY SHOULD KEEP HIGH TEMPERATURES MAINLY IN THE 70S DURING THE PERIOD. A DEVELOPING SOUTHERLY SURFACE FLOW FOR THURSDAY, AHEAD OF AN APPROACHING COLD FRONT, WILL DRAW WARM AIR INTO OUR REGION AT THAT TIME. IT SHOULD BE THE WARMEST DAY OF THE WORK WEEK WITH MAXIMUM TEMPERATURES IN THE 80S. THE INCREASING LOW LEVEL MOISTURE WILL HELP TO FUEL SHOWERS AND THUNDERSTORMS IN ADVANCE OF THE FRONTAL BOUNDARY FOR THURSDAY AFTERNOON INTO THURSDAY NIGHT. THE COLD FRONT IS ANTICIPATED TO ARRIVE EARLY ON FRIDAY WITH ANOTHER AREA OF HIGH PRESSURE FOLLOWING FOR LATE FRIDAY INTO SATURDAY. && .AVIATION /20Z SATURDAY THROUGH THURSDAY/... THE FOLLOWING DISCUSSION IS FOR KPHL, KPNE, KTTN, KABE, KRDG, KILG, KMIV, KACY AND SURROUNDING AREAS. VFR CONDS ARE EXPECTED BEFORE AND AFTER ANY SHWRS AND TSTMS MOVE THRU THE INDIVIDUAL AIRPORTS. THE LATEST RADAR SHOWED SHWRS AND TSTMS MAINLY ACRS NRN AND WRN AREAS MOVING SLOWLY EWD. TIMING HAS BEEN RECENTLY ADJUSTED ALG AND N OF THE I-95 CORRIDOR TO BRING IN THE PRECIP A BIT SOONER, BASED ON LATEST RADAR TRENDS. EXPECT MVFR/IFR WITH STRONG GUSTY WINDS AND HEAVY RAIN IF AN INDIVIDUAL ARPT IS IMPACTED BY TSRA. A CDFNT WILL MOVE THRU THE REGION TONIGHT AND BEHIND THE CFP, THE WIND WILL BECOME NW AND USHER IN A COOLER AND MORE REFRESHING AMS. EXPECT VFR CONDS ON SUN, WITH NW WIND BECOMING NE WITH SPEEDS AROUND 10 KTS. OVERALL WIND SHOULD BE 10 KTS OR LESS OUTSIDE OF ANY SHRA/TSRA OR ANY OUTFLOW FROM SUCH STORMS. OUTLOOK... SUNDAY NIGHT...MAINLY VFR. MONDAY...MAINLY VFR WITH LIGHT RAIN SPREADING INTO THE REGION FROM THE SOUTH. MONDAY NIGHT AND TUESDAY...MAINLY VFR WITH POSSIBLE MVFR CONDITIONS AT TIMES IN RAIN. TUESDAY NIGHT AND WEDNESDAY...MAINLY VFR. WEDNESDAY NIGHT AND THURSDAY...VFR EXCEPT FOR LATE NIGHT AND EARLY MORNING LOW CLOUDS AND FOG. ALSO, THERE IS A CHANCE OF AFTERNOON AND EVENING SHOWERS AND THUNDERSTORMS ON THURSDAY. && .MARINE... NO MARINE HEADLINES ARE ANTICIPATED THRU THE NEAR AND SHORT TERM PDS WITH SEAS GENLY IN THE 2 TO 4 FT RANGE AND WIND IN THE 10-15 KT RANGE OUTSIDE OF ANY TSRA THAT WILL IMPACT THE AREA LATER TODAY AND TONIGHT. OUTLOOK... SUNDAY NIGHT...NO MARINE HEADLINES ARE ANTICIPATED. MONDAY INTO TUESDAY...SMALL CRAFT ADVISORY CONDITIONS ARE POSSIBLE IN A STRONG NORTHEASTERLY FLOW. GALE FORCE GUSTS MAY OCCUR FROM MONDAY NIGHT INTO TUESDAY MORNING DEPENDING UPON THE STRENGTH OF A DEVELOPING COASTAL LOW. TUESDAY NIGHT AND WEDNESDAY...WIND SPEEDS ARE FORECAST TO FALL BELOW THE SMALL CRAFT ADVISORY CRITERION. HOWEVER, WAVES ON OUR OCEAN WATERS MAY REMAIN AROUND 5 FEET. WEDNESDAY NIGHT AND THURSDAY...NO MARINE HEADLINES ARE ANTICIPATED. && .TIDES/COASTAL FLOODING... A DEVELOPING NORTHEASTERLY SURFACE FLOW MAY RESULT IN MINOR TIDAL FLOODING ALONG THE NEW JERSEY AND DELAWARE COASTS, ALONG DELAWARE BAY AND ON THE TIDAL DELAWARE RIVER DURING THE MONDAY EVENING HIGH TIDE. THE NORTHEAST FLOW IS EXPECTED TO CONTINUE DURING THE SUBSEQUENT TWO HIGH TIDES ON TUESDAY MORNING AND TUESDAY EVENING AND IT MAY CAUSE ADDITIONAL MINOR TIDAL FLOODING. && .RIP CURRENTS...
