The episode as NWS PHI wrote it up.
A lee side trof helped trigger clusters of showers and thunderstorms during the second half of the morning and afternoon. While the greatest impact was flash flooding in the Raritan Basin of New Jersey, lightning and wind damage also occurred. About 6,000 homes and businesses lost power in the state.

NWS Philadelphia/Mount Holly wrote its last area forecast discussion before the first event at Aug 22, 7:36 AM EST, 1 hour 3 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE MOUNT HOLLY NJ 836 AM EDT THU AUG 22 2013 .SYNOPSIS... A COLD FRONT IN THE SAINT LAWRENCE RIVER VALLEY WILL MOVE SOUTHEAST TODAY AND CROSS THE AREA DURING THE FIRST HALF OF THE DAY ON FRIDAY. A LARGE AREA OF HIGH PRESSURE WILL BUILD INTO THE REGION FROM THE NORTHWEST AND SLIDE OVER OUR AREA ON THE WEEKEND BEFORE MOVING TO OUR SOUTH ON MONDAY. A WEAKENING COLD FRONT SHOULD MOVE THROUGH THE MIDDLE ATLANTIC STATES AROUND WEDNESDAY. && .NEAR TERM /UNTIL 6 PM THIS EVENING/... THE WATER VAPOR IMAGERY SHOWS AN UPPER-LEVEL LOW GRADUALLY WEAKENING OVER WEST VIRGINIA. AN UPPER AIR ANALYSIS REVEALS A SUBTLE 250 MB JET STREAK ROUNDING THE BASE OF THIS FEATURE ALONG WITH A COUPLE OF SHORT WAVES. THE ACTUAL SHORT WAVES ARE TRAVERSING OUR CWA THIS MORNING, WHICH IS TEAMING UP WITH DEEP MOISTURE, AREAS OF MOISTURE CONVERGENCE, AND A PRE-FRONTAL TROUGH TO PRODUCE POCKETS OF SHOWERS AND THUNDERSTORMS. GIVEN PW VALUES NEAR 2 INCHES, LOCALLY VERY HEAVY RAIN HAS BEEN REPORTED WITH THE STRONGER CORES WITH EVEN SOME ROADWAY AND POOR DRAINAGE FLOODING. THE MID LEVEL MOISTURE PLUME IS OVER OUR CWA THIS MORNING, HOWEVER THE WATER VAPOR IMAGERY SHOWS A DRY SLOT WORKING EASTWARD FROM SOUTH-CENTRAL PENNSYLVANIA TO CENTRAL VIRGINIA. THERE IS SOME ADDITIONAL CONVECTION DEVELOPING WITH THIS, THEREFORE WHILE THERE WILL BE BREAKS IN THE SHOWERS/STORMS SOME ACTIVITY IS EXPECTED TO PERSIST. THE ORGANIZATION IS SOMEWHAT UNCERTAIN, AND THEREFORE WE WILL CONTINUE WITH POPS NO HIGHER THAN CHC FOR SCATTERED SHOWERS AND THUNDERSTORMS. A FEW THUNDERSTORMS COULD BE LOCALLY STRONG, HOWEVER THE LACK OF STEEPER MID LEVEL LAPSE RATES, STRONGER LOW-LEVEL FLOW AND VERTICAL SHEAR SHOULD KEEP THE SEVERE THUNDERSTORM THREAT ON THE RATHER LOW SIDE. THE HOURLY GRIDS WERE ADJUSTED BASED ON THE LATEST OBSERVATIONS, THEN SOME BLENDING IN OF THE LAMP/LAV GUIDANCE WAS USED TO ASSIST WITH THE TRENDS. NO CHANGES WERE MADE TO THE HIGH TEMPERATURES, WHICH WERE MOSTLY A BLEND OF THE GFS/NAM MOS. && .SHORT TERM /6 PM THIS EVENING THROUGH 6 AM FRIDAY/... THE COLD FRONT WILL MOVE INTO PENNSYLVANIA THIS EVENING AND THEN INTO OUR AREA BY LATE TONIGHT. THE FRONT WILL BE SLOW MOVING AND IS NOT EXPECTED TO MOVE OFFSHORE UNTIL FRIDAY MORNING. IN ADVANCE OF THE FRONT, WE WILL HAVE ONGOING SCATTERED SHOWERS AND THUNDERSTORMS. THIS ACTIVITY WILL DIMINISH IN COVERAGE FROM WEST TO EAST AS THE FRONT MOVES THROUGH. LOW TEMPERATURES WERE A BLEND OF THE GFS/NAM MOS. CLOUDS WILL BE AROUND ALL NIGHT AND WILL KEEP THE TEMPERATURES WARMER THAN NORMAL FOR LATE AUGUST. && .LONG TERM /FRIDAY THROUGH WEDNESDAY/... THE GFS INITIALIZATION LOOKED BETTER THAN THE WRF-NMMB AT 500MB AND 850MB. THE LATTER LOOKED BETTER OVER THE LOCAL AREA AT 925MB, BUT UPWIND THE GFS LOOKED BETTER. THE GFS WAS PART OF WPC'S PREFERENCE AND THUS WAS GIVEN MORE WEIGHT THAN AVERAGE THROUGH THE LONG TERM. THAT BEING SAID, THE MODEL SPREAD TOWARD THE END OF THE LONG TERM REMAINS PRETTY LARGE AND WE WENT MORE ALONG THE LINES OF PRESERVING CONTINUITY UNTIL A MORE CONVERGENT SOLUTION EVOLVES. FOR THE START OF THE LONG TERM FRIDAY ITS A RACE BETWEEN TOO MUCH DRY AIR MAKING IT IMPOSSIBLE FOR CONVECTION AND ANY RESIDUAL LIFT FROM THE SAGGING SOUTHWARD FRONT. THE GFS WAS SLIGHTLY SLOWER THAN ITS PRECEDING SOUNDING RUN. BUT ALL OF THE FORECAST SOUNDINGS ARE EITHER CAPPED OR WAY TOO DRY TO SUPPORT CONVECTION NORTH. WE DID SHAVE BACK THE MENTION OF PCPN IN OUR CWA AND POPS ARE PRETTY CLOSE TO SPC'S SWODY2 GENERAL THUNDER. DID NOT WANT TO REMOVE POPS COMPLETELY AS SREF FCST CAPE AS WELL AS GFS FCST MLYR CAPE STILL WOULD SUPPORT A CHANCE SOUTH. GIVEN THAT THERE IS WEST OR NORTHWEST FLOW AND A FCST DECREASE OF THETA E WE KEPT POPS PRETTY LOW. THE POSITIONING OF THE JET LOOKS GOOD, BUT ONE STILL NEEDS MOISTURE TO BE LIFTED WHICH MAY BE THE ONE BIG MISSING INGREDIENT. THE KATABATIC FLOW SHOULD HELP MAXIMIZE MAX TEMP POTENTIAL AND WE WENT TOWARD THE WARMER NAM MOS. WE SUPPOSE IF THE JET DEVELOPS MORE CIRRUS THAN ANTICIPATED WE MIGHT BE TOO EXUBERANT WITH THE MAX TEMPS. A CLEAR NIGHT IS EXPECTED ON FRIDAY NIGHT. THERE SHOULD BE TOO MUCH OF AN INITIAL GRADIENT FOR AN IDEAL RADIATIONAL COOLING NIGHT. THE TRAJECTORY AROUND THE SURFACE HIGH ALSO CASTS SOME DOUBT FOR THE EASTERN PART OF OUR CWA. THUS WE WERE MORE BULLISH ABOUT MINIMUM TEMPS NORTHWEST OF I95 THAN SOUTHEAST. WE ARE SLIGHTLY LESS CONFIDENT ABOUT THE AMOUNT OF SUNSHINE ON SATURDAY VS SUNDAY AS THE FLOW AROUND THE SURFACE HIGH IS STRONGER ONSHORE SATURDAY THAN SUNDAY WHEN IT BECOMES VERY LIGHT. RIGHT NOW THE GFS FCST MOISTURE IS EXTREMELY LOW EVEN WITH THE OCEANIC TRAJECTORY. THE COUPLE OF HUNDREDTHS THE MODEL MANUFACTURES SEEMS TIED TO DEW POINTS WHICH SHOULD VERIFY TOO HIGH. EITHER WAY TEMPERATURES SHOULD AVERAGE AT OR LOWER THAN NORMAL WITH LOW HUMIDITY LEVELS BOTH DAYS. THE SUNDAY MORNING MINS FOLLOW THE MORE TRADITIONAL RADIATIONAL COOLING PATTERN IN NON URBAN AREAS WITH MINS IN INTERIOR DELMARVA LOWER THAN PHL AND THE PINE BARRENS COMPARABLE TO OUTLYING AREAS NW OF I95. THEN WE WILL START THE AIR MASS MODIFICATION PROCESS ON MONDAY. THE 00Z MODEL SUITE WAS SLOWER IN BRINGING BACK SUFFICIENT MOISTURE FOR PCPN, SO WE REMOVED OUR LOW CHANCES FOR MONDAY. THEN THE REST OF THE LONG TERM WE KEPT CLOSE TO CONTINUITY. THE MODELING TREND HAS BEEN LEANING AWAY FROM THE HEAT RIDGE MAKING IT OUT OF THE CENTRAL MISSISSIPPI AND LOWER OHIO VALLEYS. THIS WOULD LEAVE OUR CWA IN THE RING OF FIRE AROUND THIS SYSTEM WITH FRONTAL BOUNDARIES TRYING TO WORK THEIR WAY THROUGH OUR CWA. WHILE WE SHOULD GET WARMER AND MORE HUMID, THE CURRENT MODELING TREND MIGHT PREVENT MOST OF US FROM REACHING 90F AND REMAINING IN THAT RING WILL GIVE US SHOWER AND THUNDERSTORM CHANCES BOTH TUESDAY AND WEDNESDAY. && .AVIATION /13Z THURSDAY THROUGH MONDAY/... THE FOLLOWING DISCUSSION IS FOR KPHL, KPNE, KTTN, KABE, KRDG, KILG, KMIV, KACY AND SURROUNDING AREAS. TODAY...VARYING CEILINGS AS A WEALTH OF LOW-LEVEL MOISTURE IS AROUND THIS MORNING. THE MVFR/IFR CEILINGS ARE THINNING FROM THE SOUTHWEST, THEREFORE IMPROVING CONDITIONS ARE ANTICIPATED. SOME SHOWERS AND THUNDERSTORMS AROUND THIS MORNING ASSISTING IN LOWER VISIBILITIES/CEILINGS AT TIMES WITH DOWNPOURS. THE CONDITIONS ARE ANTICIPATED TO IMPROVE TO VFR BY ABOUT MIDDAY ACROSS THE AREA, HOWEVER A COLD FRONT WILL GRADUALLY APPROACH FROM THE WEST WITH SOME ADDITIONAL SHOWERS AND THUNDERSTORMS OCCURRING. OUR CONFIDENCE REMAINS SOMEWHAT REDUCED ON THE TIMING AND LOCATION OF THUNDERSTORMS AFTER THE CURRENT ACTIVITY SHIFTS OUT OF THE AREA. IT APPEARS THOUGH THE BETTER TIMING IS BETWEEN 19-22Z, AND WE HAVE ADDED A TEMPO GROUP TO SEVERAL OF THE TAFS TO INDICATE THIS. AMENDMENTS WILL BE ISSUED TO ADJUST THE TIMING, ESPECIALLY BASED ON RADAR TRENDS. SOUTHWESTERLY WINDS NEAR 5 KNOTS SHOULD INCREASE TO ABOUT 10 KNOTS ESPECIALLY THIS AFTERNOON. TONIGHT...VFR OVERALL, HOWEVER LOCAL MVFR/IFR POSSIBLE WITH SOME LINGERING SHOWERS AND THUNDERSTORMS. THE COLD FRONT WILL ARRIVE LATER, AND DUE TO THE TIMING AT NIGHT THERE MAY NOT BE A LOT OF CONVECTION WITH IT. WEST-SOUTHWEST WINDS 5-10 KNOTS, BECOMING NORTHWEST LATE. OUTLOOK... FRIDAY...MVFR CONDITIONS POSSIBLE EARLY ALL AREAS AND LOCALLY SOUTHEAST IN ANY LEFTOVER SHOWERS OR THUNDERSTORMS. FRIDAY NIGHT THROUGH MONDAY...PREDOMINATELY VFR CONDITIONS. SOME MORNING FOG POSSIBLE SUNDAY AND MONDAY AT MORE RURAL AIRPORTS. MORNING VISIBLE SATELLITE PHOTOS WILL LIKELY SHOW FOG WITHIN SOME OF THE LARGER RIVER VALLEYS. && .MARINE... SUB-ADVISORY CONDITIONS WILL CONTINUE ACROSS THE AREA WATERS. THE HIGH HAS SETTLED TO THE SOUTHEAST OF THE REGION AND THE AREA WATERS REMAIN FAIRLY CALM. SEAS ARE AROUND 2 FEET ON THE OCEAN AND 1 TO 2 FEET IN THE DELAWARE BAY. WINDS WILL BE OUT OF A SOUTHERLY DIRECTION WITH SPEEDS AROUND 10 KNOTS. WINDS WILL START TO TURN MORE TO THE WEST...THEN NORTHWEST AS A COLD FRONT APPROACHES AND THEN CROSSES THE WATERS LATE TONIGHT INTO FRIDAY MORNING. SHOWERS AND THUNDERSTORMS WILL BE AROUND THE REGION THROUGH THE DAY WHICH MAY CAUSE LOCALLY HIGHER SEAS AND WIND GUSTS. OUTLOOK... SUB SMALL CRAFT ADVISORY CONDITIONS ARE EXPECTED TO CONTINUE THROUGH THE OUTLOOK PERIOD. THE LOWEST CONFIDENCE ABOUT THIS OUTLOOK IS ON CALENDAR DAY SATURDAY AS THERE SHOULD BE AN ONSHORE FLOW BEFORE THE HIGH PRESSURE SYSTEM BUILDS IN DEEPER INTO OUR MARINE AREA. BOTH WINDS AND SEAS MIGHT COME CLOSE TO ADVISORY CRITERIA SATURDAY ON THE OCEAN. AFTER THAT AS THE HIGH PRESSURE SYSTEM SETTLES SOUTHWARD ON SUNDAY INTO MONDAY, THERE IS GREATER CONFIDENCE ABOUT REMAINING BELOW SMALL CRAFT ADVISORY CONDITIONS. && .PHI WATCHES/WARNINGS/ADVISORIES...
