Widely scattered strong to locally severe thunderstorms developed along a lee side trough and affected the Philadelphia northern suburbs during the late afternoon of the 6th. While lightning was responsible for most of the PECO Energy outages (about 5,500 customers in Bucks and eastern Montgomery Counties), some wind damage occurred near the New Jersey border in lower Bucks County.

The episode as NWS PHI wrote it up.
Widely scattered strong to locally severe thunderstorms developed along a lee side trough and affected the Philadelphia northern suburbs during the late afternoon of the 6th. While lightning was responsible for most of the PECO Energy outages (about 5,500 customers in Bucks and eastern Montgomery Counties), some wind damage occurred near the New Jersey border in lower Bucks County.
The local office's own words before the first event, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.
NWS Philadelphia/Mount Holly wrote its last area forecast discussion before the first event at Jul 6, 2:33 PM EST, 52 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE MOUNT HOLLY NJ 333 PM EDT WED JUL 6 2011 .SYNOPSIS... A WEAK COLD FRONT WILL SLOWLY SAG INTO THE AREA TONIGHT, THEN STALL NEAR THE AREA THURSDAY, THEN SLOWLY CONTINUE TO MOVE THROUGH THE AREA FRIDAY AS AN AREA OF LOW PRESSURE DEVELOPS ALONG THE BOUNDARY. THE FRONT SHOULD MOVE SOUTH OF THE AREA SATURDAY, WHILE HIGH PRESSURE BUILDS IN FOR THE LATTER PART OF THE WEEKEND. ANOTHER FRONTAL BOUNDARY IS EXPECTED AROUND TUESDAY NEXT WEEK. && .NEAR TERM /UNTIL 6 AM THURSDAY MORNING/... SHOWERS AND THUNDERSTORMS CONTINUE TO DEVELOP LATE THIS AFTERNOON AND WILL CONTINUE INTO THE EVENING AS A SHORTWAVE/VORTICITY MAXIMUM MOVES THROUGH THE AREA. A FRONTAL BOUNDARY WILL CONTINUE TO MOVE SOUTH INTO THE AREA FROM THE NORTHEAST WHICH COULD CONTINUE SOME SHOWERS/THUNDERSTORMS INTO THE EVENING HOURS. THE CONVECTION SHOULD BEGIN TO DIMINISH AS THE SUN SETS, BUT WE MAINTAIN A SLIGHT CHANCE OF POPS OVERNIGHT. ALTHOUGH WE HAVE QUITE A BIT OF INSTABILITY /2000-3000 J/KG OF CAPE AND LI'S AROUND -4 TO -6/ SHEAR VALUES ARE NOT THE GREATEST /GENERALLY AROUND OR BELOW 20 KNOTS/ SO WIDESPREAD SEVERE WEATHER IS NOT EXPECTED. HOWEVER, WITH THE HIGH INSTABILITY, WE COULD HAVE A FEW STRONG TO SEVERE STORMS WHICH WE HAVE HAD ALREADY. HEAVY RAIN, FREQUENT LIGHTNING, ALONG WITH GUSTY WINDS AND SMALL HAIL ARE POSSIBLE. && .SHORT TERM /6 AM THURSDAY MORNING THROUGH SATURDAY/... THE COLD FRONT IS EXPECTED TO STALL ACROSS THE FORECAST AREA ON THURSDAY AND NOT MAKE MUCH PROGRESS THROUGH MUCH OF THE DAY. WE WILL HAVE A FAIR AMOUNT OF MOISTURE IN THE ATMOSPHERE, AND IT WILL BE QUITE HOT AND HUMID. HOWEVER, WE DO NOT HAVE MUCH OF ANY STRONG UPPER LEVEL FORCING /I.E SHORTWAVE OR VORTICITY MAX/ SO WE ARE NOT EXPECTING WIDESPREAD CONVECTION TOMORROW. BUT WITH THE INSTABILITY AND MOISTURE, WE COULD HAVE SOME SHOWERS/THUNDERSTORMS DEVELOPING DURING THE AFTERNOON. AS MENTIONED BEFORE, THE FRONTAL BOUNDARY IS EXPECTED TO STALL NEAR THE AREA AND NOT MAKE MUCH PROGRESS THROUGH THURSDAY NIGHT INTO FRIDAY, BEFORE BEGINNING TO DRIFT SOUTHWARD FRIDAY NIGHT. STARTING THURSDAY NIGHT INTO FRIDAY AND FRIDAY NIGHT, SEVERAL SHORTWAVES ALOFT ARE EXPECTED TO CROSS THE AREA, WHILE AN AREA OF LOW PRESSURE DEVELOPS ALONG THE FRONTAL BOUNDARY ON FRIDAY. THESE SHORTWAVES SHOULD HELP TO CREATE A BETTER CHANCE OF SHOWERS/THUNDERSTORMS FROM THURSDAY NIGHT INTO FRIDAY NIGHT. FRIDAY AFTERNOON INTO FRIDAY NIGHT LOOKS TO BE THE BEST PROBABILITY FOR PRECIPITATION AS THE STRONGEST SHORTWAVE/VORTICITY MAX AND SURFACE LOW PRESSURE ALONG THE FRONT CROSS THE REGION. BY SATURDAY, THE FRONT SHOULD HAVE MADE IT OFF THE COAST, AND PRECIPITATION CHANCES SHOULD DIMINISH BEHIND IT. HOWEVER, WE DO MAINTAIN A SLIGHT CHANCE OF SHOWERS/THUNDERSTORMS ON SATURDAY AS A SHORTWAVE CROSSING TO THE NORTH MAY HELP SPARK OFF SOME CONVECTION DURING THE DAY WITH THE HEAT AND INSTABILITY. ONE THING TO NOTE IS THAT EVEN THOUGH WE HAVE A CHANCE OF PRECIPITATION EACH DAY THROUGH SATURDAY, WE WILL HAVE PERIODS OF NO PRECIPITATION. FOR TEMPERATURES THROUGH THE PERIOD, WE TOOK A BLEND OF MOS, BUT STAYED CLOSER TO THE MAV MOS. THICKNESSES DO NOT CHANGE MUCH OVER THE NEXT FEW DAYS, BUT WITH CLOUDS AND RAIN AND AN EASTERLY FLOW ON FRIDAY, IT SHOULD BE THE COOLEST DAY OF THE NEXT THREE. THURSDAY IS EXPECTED TO BE THE WARMEST WITH TEMPERATURES REACHING THE UPPER 80S TO LOW 90S FOR MOST AREA AWAY FROM THE WATER AND HIGHER ELEVATIONS. && .LONG TERM /SATURDAY NIGHT THROUGH WEDNESDAY/... THE NORTHERN FLOW REMAINS ACTIVE DURING THIS TIME FRAME AS RIDGING REMAINS MOSTLY INTACT ACROSS THE SOUTHERN STATES. THIS PATTERN REGIME WILL ALLOW SYSTEMS TO SLIDE ACROSS THE NORTHERN TIER OF STATES WITH THEIR ASSOCIATED COLD FRONTS MOVING THROUGH BUT THEN STALLING SOUTHWARD DUE TO THE RIDGING. THE ECMWF ENSEMBLE MEAN HAS BEEN SHOWING GOOD CONTINUITY FOR QUITE SOME TIME. HPC BLENDED IN THE LATEST ECMWF ENSEMBLE MEAN WITH THE PREVIOUS ONE. WE INITIALIZED THE DATABASE WITH HPC GUIDANCE THEN MADE SOME TWEAKS AFTER ADDITIONAL COLLABORATION WITH OUR NEIGHBORING OFFICES. BASED ON THE ABOVE, HIGH PRESSURE ACROSS THE AREA SATURDAY NIGHT AND SUNDAY WILL EVENTUALLY SLIDE TO OUR EAST. THE MOISTURE AND THERMAL ADVECTIONS ON THE BACKSIDE OF THIS HIGH AND AHEAD OF A COLD FRONT SHOULD ALLOW A STALLED FRONT TO OUR SOUTH TO WORK NORTHWARD AS A WARM FRONT MONDAY. AT THIS POINT, THERE DOES NOT LOOK LIKE MUCH OF A TRIGGER FOR CONVECTION WITH THE WARM FRONT ITSELF. THE COLD FRONT SETTLES ACROSS OUR AREA MONDAY NIGHT INTO TUESDAY, BUT WILL PROBABLY TEND TO SLOW ITS SOUTHWARD MOVEMENT TUESDAY DUE TO BECOMING REMOVED FROM THE STRONGER FLOW AND RIDGING FARTHER TO THE SOUTH. AS HIGH PRESSURE MOVES ACROSS THE GREAT LAKES REGION TUESDAY AND WEDNESDAY, THIS SHOULD PUSH THE FRONT SOUTH OF OUR DELMARVA ZONES. WE WILL BRING IN SOME SLIGHT CHC POPS ACROSS OUR NORTHWEST ZONES MONDAY THEN EXPAND THIS ALONG WITH LOW CHC POPS MONDAY NIGHT AND TUESDAY AS THE FRONT ARRIVES. WE HELD ONTO SOME SLIGHT CHC POPS WEDNESDAY MAINLY ACROSS PORTIONS OF OUR DELMARVA ZONES IN THE EVENT THE FRONT DOES NOT SETTLE FAR ENOUGH SOUTH. THIS PATTERN LOOKS TO FAVOR WARM TO HOT CONDITIONS THROUGH THE ENTIRE TIME FRAME, AND WE DID NOT MAKE ANY SIGNIFICANT CHANGES TO THE HPC TEMPERATURE GUIDANCE. && .AVIATION /20Z WEDNESDAY THROUGH MONDAY/... THE FOLLOWING DISCUSSION IS FOR KPHL, KPNE, KTTN, KABE, KRDG, KILG, KMIV, KACY AND SURROUNDING AREAS. A HOT AND HUMID AIR MASS COMBINED WITH A SLOW-MOVING BUT WEAK FRONTAL BOUNDARY OVER/NEAR THE AREA ARE COMBINING TO PRODUCE POPUP THUNDERSTORMS ACROSS THE CWA THIS AFTERNOON, ESPECIALLY SOUTH OF THE LEHIGH VALLEY. A THUNDERSTORM CANNOT BE RULED OUT ANYWHERE, SO A CB GROUP HAS BEEN INCLUDED AT ALL TAF SITES FOR THE REMAINDER OF THE AFTERNOON, AND INTO THE EVENING HOURS SOUTH OF THE LEHIGH VALLEY. THE SEABREEZE MOVED WEST OF ACY BY EARLY WED AFTN AND SO A SOUTHEAST COMPONENT IS EXPECTED THERE THROUGH THE AFTN HOURS. AFTER SUNSET A SOUTHWESTERLY WIND IS EXPECTED. WINDS ARE THEN EXPECTED TO BECOME LIGHT AND VARIABLE AT ALL TAF SITES DURING THE LATE OVERNIGHT HOURS WHICH, ALONG WITH TEMP-DEWPOINT DEPRESSIONS AT OR UNDER 4 DEGREES, WILL SET THE STAGE FOR SOME POSSIBLE VSBY RESTRICTIONS TOWARD MORNING...ESPECIALLY AT RDG, MIV AND ACY. THEN MORE POPUP THUNDERSTORMS POSSIBLE AGAIN THURSDAY AFTERNOON. OUTLOOK... THE FRONT WILL NOT CLEAR THE AREA UNTIL SOMETIME LATER FRIDAY... MEANING THAT SCATTERED SHOWERS AND THUNDERSTORMS WILL CONTINUE THROUGH THEN. MOST OF THE TIME WILL FEATURE VFR CONDITIONS...WITH LOCAL MVFR CONDITIONS IN THUNDERSTORMS. AFTER THE FRONT MOVES EAST OF THE AREA AND HIGH PRESSURE BUILDS IN FROM THE WEST...VFR CONDITIONS ARE EXPECTED FOR THE WEEKEND. && .MARINE... A SLOWLY-MOVING BUT WEAK FRONTAL BOUNDARY APPROACHING THE FORECAST WATERS ALONG WITH AN ESTABLISHED MOIST AIR MASS WILL CONTINUE TO PRODUCE MAINLY AFTERNOON AND EARLY EVENING THUNDERSTORMS OF THE SCATTERED VARIETY TODAY AND THURSDAY. THE GENERAL WIND PATTERN THROUGH THIS PERIOD WILL BE SOUTHWEST IN THE 10 TO 15 KT RANGE WITH LOCAL VARIABILITY DUE TO THUNDERSTORM OR SEABREEZE DEVELOPMENT. THE FRONTAL BOUNDARY IS THEN PROGGED TO STALL JUST OFF THE COAST, ALLOWING LOW PRESSURE FROM THE EASTERN CAROLINAS TO MOVE ALONG IT FRIDAY NIGHT AND SATURDAY. RIGHT NOW WINDS AND SEAS ARE EXPECTED TO REMAIN BELOW SCA CRITERIA, BUT ANYTIME A FRONTAL BOUNDARY HANGS AROUND THE FORECAST TERRITORY, CONDITIONS CAN CHANGE FAIRLY QUICKLY. HIGH PRESSURE IS THEN EXPECTED TO BUILD IN FROM THE WEST LATE SATURDAY AND DOMINATING THE WEATHER PATTERN OVER THE FORECAST WATERS THROUGH MONDAY. && .PHI WATCHES/WARNINGS/ADVISORIES... PA...NONE.
