The episode as NWS PHI wrote it up.
A powerful squall line of strong to severe thunderstorms moved through Eastern Pennsylvania during the very late afternoon and first half of the evening on the 26th. Over 17,000 homes and businesses lost power because of downed trees, tree limbs and wires. More than 10,000 still did not have power on the morning of the 27th.
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.

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MOUNT HOLLY NJ
338 PM EDT THU JUL 26 2012
.SYNOPSIS...
LOW PRESSURE OVER NEW YORK STATE THIS AFTERNOON WILL MOVE EAST
ACROSS NEW ENGLAND TONIGHT AND FRIDAY MORNING. AN ATTACHED COLD
FRONT WILL MOVE SOUTH OF DELMARVA LATE BY SATURDAY NIGHT. WEAK
HIGH PRESSURE FOLLOWS SUNDAY THROUGH TUESDAY. LOW PRESSURE DEVELOPS
ALONG A BOUNDARY TO OUR SOUTH AND STAYS JUST OFFSHORE ON
WEDNESDAY.
&&
.NEAR TERM /UNTIL 6 AM FRIDAY MORNING/...
HEAT, HUMIDITY AND CONVECTION ARE THE MAIN CONCERNS THROUGH THIS
EVENING. THE WARM FRONT IS LOCATED JUST NORTH OF OUR AREA THIS
AFTERNOON WITH A STRONG SOUTHWEST FLOW BEHIND IT. THIS HAS ALLOWED
WARM, MOIST AIR TO OVERSPREAD THE REGION THIS AFTERNOON. WHILE
TEMPERATURES ARE NOT QUITE AS HOT AS EXPECTED, THEY HAVE STILL
MANAGED TO REACH INTO THE LOWER 90S IN MANY AREAS WITH THE DEWPOINTS
RISING INTO THE 70S. HEAT INDEX VALUES WILL REMAIN NEAR 100+ THROUGH
THIS AFTERNOON.
CLOUDS HAVE THINNED AND ALLOWED THE SURFACE TO START TO HEAT UP,
ALLOWING FOR THE CAP TO BREAK THIS AFTERNOON. WHILE WE ARE
MARGINALLY UNSTABLE AT THE MOMENT, WE WILL CONTINUE TO DESTABILIZE
THIS AFTERNOON AND EVENING AHEAD OF THE LINE OF STORMS TO OUR WEST.
THE AREA REMAINS IN A MODERATE RISK, MINUS THE MAJORITY OF DELMARVA
AND SOUTHERN NEW JERSEY WHERE A SLIGHT RISK IS STILL IN PLACE. A
LINE OF STORMS HAS DEVELOPED OVER WESTERN PENNSYLVANIA THIS
AFTERNOON AHEAD OF A COLD FRONT AND WILL CONTINUE TO TRACK EASTWARD
OVER THE NEXT SEVERAL HOURS. THE LINE TO THE WEST IS PACKING QUITE A
PUNCH. WE DON'T EXPECT IT TO DIE DOWN MUCH AS IT PUSHES EASTWARD
WITH MANY OF THE CELLS SHOWING A BOWING STRUCTURE. CURRENT TIMING
SUGGESTS THAT THE STORMS WILL START TO MOVE INTO OUR AREA CLOSER TO
6-7PM AND THEN CONTINUE EASTWARD, FINALLY EXITING OUR AREA AROUND
11PM-MIDNIGHT. PLEASE STAY IN A SAFE LOCATION AS THE STORMS MOVE
THROUGH AS FREQUENT LIGHTNING IS EXPECTED.
OVERNIGHT WE MAY SEE SOME LINGERING SHOWERS BUT MANY PLACES WILL SEE
A LITTLE BREAK FROM IT ALL. TEMPERATURES REMAIN MILD, REACHING INTO
THE 70S TO NEAR 80 ACROSS THE REGION. WITH TEMPERATURES NEAR 80 IN
THE URBAN AREAS, THERE WILL BE VERY LITTLE RELIEF FROM THE HEAT AND
THE WARNING WILL REMAIN IN PLACE IN THOSE AREAS.
LOOKS TO BE CLOUDIER THE FURTHER NORTH YOU GO TONIGHT BUT IN AREAS
WHERE RAIN HAS FALLEN WE COULD SEE SOME PATCHY FOG DEVELOP.
&&
.SHORT TERM /6 AM FRIDAY MORNING THROUGH 6 PM FRIDAY/...
EXCESSIVE HEAT WARNING WILL CONTINUE THROUGH FRIDAY. THE HEAT
ADVISORY FOR SOUTHERN NJ AND THE DELMARVA HAS BEEN EXTENDED THROUGH
FRIDAY.
FOR FRIDAY...THE COLD FRONT STARTS TO PUSH SOUTHWARD INTO THE AREA.
IT IS SLOW MOVING AND LOOKS TO STALL OVER OR NEAR OUR AREA FRIDAY
AFTERNOON. THIS BOUNDARY MAY BE THE FOCUS FOR MORE CONVECTION ON
FRIDAY BUT IT APPEARS TO BE MORE SCATTERED IN NATURE THAN WHAT WE
ARE SEEING FOR TODAY.
BEHIND THE FRONT WINDS WILL VEER TO THE WEST NORTHWEST ALLOWING SOME
DRIER AIR TO PUSH INTO THE AREA, ESPECIALLY ACROSS OUR MORE
NORTHWESTERN ZONES. ACROSS THE SOUTH, THE FRONT WILL TAKE ITS TIME
GETTING THERE. WHILE IT LOOKS LIKE IT STALLS IT MAY JUST BE MOVING
VERY VERY SLOWLY, KEEPING THE SOUTHERN AREAS IN THE WARM, MOIST AIR
LONGER. THIS WILL CONTRIBUTE TO HIGHER TEMPERATURES IN THE SOUTHERN
AREAS AS WELL AS HIGH HEAT INDEX VALUES AGAIN FOR ANOTHER DAY. HEAT
INDEX VALUES THROUGH THE URBAN AREAS WILL ONCE AGAIN RISE NEAR
100-102 FOR A COUPLE OF HOURS AND THE WARNING WILL BE LEFT IN PLACE
FOR ANOTHER DAY.
&&
.LONG TERM /FRIDAY NIGHT THROUGH THURSDAY/...
THE PROGRESSIVE UPPER TROUGH THAT WILL BE OVER THE GREAT LAKES
DURING THE SHORTER RANGES OF THE FCST WILL MOVE EAST AND SETTLE
ALONG THE MIDDLE ATLANTIC AND NORTHEAST THIS WEEKEND. THIS WILL
BRING UNSETTLED CONDITIONS WITH PARTLY TO MOSTLY CLOUDY PERIODS
AND CHC FOR SHOWERS AND AFTERNOON TSTMS. POPS FOR THIS FCST WILL
BE IN THE CHC RANGE FOR FRI NIGHT THROUGH SAT NIGHT. RIDGING AND
AN APPROACHING SFC HIGH SUN AND MON WILL BRING DRIER AIR AND
DECREASING CHCS FOR ANY SHOWERS...STILL KEPT SLGT CHC FOR SUN ATTM
TO ALIGN BETTER WITH NEARBY WFOS. THE UPPER TROUGH BEGINS TO
DEEPEN OVER THE AREA AGAIN TUE-WED SO PRECIP CHANCES WERE RAISED
BACK INTO THE CHC RANGE FOR THOSE PERIODS.
TEMPERATURES DURING THE EXTENDED RANGE WILL AVERAGE OUT IN THE
ABOVE NORMAL RANGE. SATURDAY WILL LIKELY SEE THE HIGHEST
TEMPERATURES OF THE EXTENDED PERIOD WITH PLENTY OF UPPER 80S AND
LOW 90S OVER THE AREA. READINGS SHOULD THEN SHOW A VERY SLOW
DECREASE INTO NEXT WEEK WITH HIGHS MOSTLY IN THE MID TO UPPER 80S.
&&
.AVIATION /19Z THURSDAY THROUGH TUESDAY/...
THE FOLLOWING DISCUSSION IS FOR KPHL, KPNE, KTTN, KABE, KRDG, KILG,
KMIV, KACY AND SURROUNDING AREAS.
VFR CONDITIONS WILL CONTINUE INTO THE EARLY EVENING BEFORE WE BECOME
IMPACTED BY SHOWERS AND THUNDERSTORMS. A LINE TO THE WEST WILL PUSH
EASTWARD AHEAD OF A SURFACE COLD FRONT. THESE STORMS WILL START TO
MOVE INTO THE AREA AROUND 21-22Z AND MOVE PRETTY QUICKLY EASTWARD,
IMPACTING NEARLY ALL OF THE TAF SITES THIS EVENING. WINDS WILL
BECOME VERY GUSTY AND FOR NOW HAVE COVERED UP TO 30 KNOTS IN THE
TAFS, ALTHOUGH WE COULD SEE GUSTS HIGHER THAN THAT AS THE STORMS
MOVE THROUGH.
CHANCE FOR THUNDER WILL DECREASE LATER TONIGHT AND A FEW LINGERING
SHOWERS MAY HANG AROUND THROUGH ABOUT 4-5Z. PATCHY FOG IS POSSIBLE
IN AREAS WHERE IT RAINS TONIGHT WITH KRDG AND KMIV BEING THE SITES
MOST LIKELY IMPACTED, MVFR POSSIBLE. FOG WOULD MAINLY BE AFTER 6-7Z
AND SHOULD LIFT BY AROUND 12Z.
WINDS REMAIN OUT OF THE SOUTHWEST THIS AFTERNOON AND WILL BECOME
MORE WESTERLY ON FRIDAY BEFORE STARTING TO VEER MORE TO THE
NORTHEAST BEHIND A COLD FRONT. THE FRONT STARTS TO PUSH SOUTHWARD
THROUGH THE AREA EARLY ON FRIDAY BUT IT IS SLOW MOVING AND IT MAY
TAKE A WHILE FOR IT MOVE THROUGH THE TAF SITES.
OUTLOOK...
FRI NIGHT-SAT NIGHT...VFR MUCH OF THE TIME BUT SCATTERED SHOWERS
AND A FEW TSTMS MAY BRING LOCALLY POOR CONDITIONS.
SUN-MON NIGHT...VFR.
TUE...MOSTLY VFR. SCATTERED SHOWERS AND A FEW TSTMS MAY BRING
LOCALLY POOR CONDITIONS.
&&
.MARINE...
SMALL CRAFT ADVISORY CONTINUES ON THE OCEAN THROUGH FRIDAY MORNING.
WE HAVE DROPPED THE ADVISORY ON THE DELAWARE BAY AS WINDS HAVE
FALLEN BELOW CRITERIA.
SOUTHWEST WINDS WILL CONTINUE ACROSS OUR WATERS THIS EVENING
BECOMING MORE WESTERLY ON FRIDAY AS A COLD FRONT SAGS SOUTHWARD
THROUGH THE AREA. WINDS WILL CONTINUE TO GUST AROUND 25-30 KNOTS ON
THE OCEAN BEFORE STARTING TO DECREASE EARLY FRIDAY MORNING. THROUGH
THE DAY ON FRIDAY, WINDS SPEEDS WILL GENERALLY BE AROUND 10 KNOTS OR
LESS. SEAS WILL REMAIN AROUND 5 FEET THROUGH TONIGHT BEFORE
SUBSIDING EARLY FRIDAY.
STRONG TO SEVER STORMS ARE POSSIBLE ON THE AREA WATERS THIS EVENING
AND INTO THE OVERNIGHT HOURS. SEAS AND WINDS WILL RESPOND QUICKLY TO
THESE STORMS.
OUTLOOK...
SUB-SCA CONDITIONS ARE EXPECTED THIS WEEKEND AND INTO EARLY NEXT
WEEK. SCATTERED TSTMS FRI NIGHT THROUGH SAT NIGHT WILL BRING
LOCALLY HIGHER WINDS AND SEAS.
