The episode as NWS PHI wrote it up.
An approaching cold front helped trigger a series of strong to severe thunderstorms across Delaware during the afternoon and evening of the 28th. The most severe storms affected New Castle County. Delmarva Power and Light reported about 3,000 homes and businesses lost power in the state and power was not fully restored until the 29th.

NWS Philadelphia/Mount Holly wrote its last area forecast discussion before the first event at Jun 28, 2:44 PM EST, 21 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE MOUNT HOLLY NJ 344 PM EDT FRI JUN 28 2013 .SYNOPSIS... LOW PRESSURE WILL LIFT NORTHWARD INTO SOUTHEASTERN CANADA THROUGH SATURDAY. THE ASSOCIATED COLD FRONT WILL MOVE INTO THE AREA TONIGHT BEFORE STALLING. THIS FRONTAL BOUNDARY WILL REMAIN NEAR OUR AREA THROUGH THE END OF THE WEEK BEFORE DISSIPATING INTO THE WEEKEND. BERMUDA HIGH PRESSURE LOCATED OVER THE WESTERN ATLANTIC WILL PUSH IN FROM THE EAST DURING THE WEEK. && .NEAR TERM /UNTIL 6 AM SATURDAY MORNING/... SEL7 IN PROGRESS. PLEASE FOLLOW ALL MOUNT HOLLY WARNINGS...STATEMENTS LOCAL STORM REPORTS AND PUBLIC INFORMATION STATEMENTS. PLEASE SEND ANY DAMAGE REPORTS OR RAINFALL OR UNUSUAL FLOODING REPORTS TO THE NWS VIA FACEBOOK...OR OTHER CHANNELS NORMALLY USED TO COMMUNICATE WITH OUR OFFICE. REMAINDER OF TODAY... WE THINK THE PRIMARY EVENT WILL BE DELMARVA... BASICALLY PHL AND JUST SOUTH. THE PRIMARY BAND OF STG-ISOLATED SVR TSTMS DEVELOP IN S CENTRAL PA SWD TO MD DURING MID OR LATE AFTN AND QUICKLY ADVECT - DEVELOP EWD INTO OUR AREA. THIS IS PER TRADITIONAL MODEL PLAN VIEW MASS FIELDS INDICATING KI POPPING UP TO 35C WITH TT NEAR 48C LATE TODAY. THESE STORMS WILL HAVE ABOUT 1400J ML CAPE TO WORK WITH MUCH GREATER 0-6KM BULK SHEAR ARRIVING LATE IN THE DAY...35-45 KT E PA DELMARVA. THE THINKING FROM OUR SHIFT AND THE PRIOR SHIFT... FOCUS ON DELMARVA FOR WIND DAMAGE BETWEEN ROUGHLY 4 PM AND 10 PM. THE PWAT WILL BE DOWN NEAR 1.7 INCHES TODAY... LESS THAN YDY BUT STILL AMPLE FOR 1 HOUR RAINFALL OF AT LEAST 1.7 INCHES SHOULD TSTMS REMAIN OVER AN AREA FOR 1 HOUR. HIGHS IN THE UPPER 80S WITH GRADIENT WIND SW G 20 KT THIS AFTN WITH MIXED CLOUDS AND SUN...PROBABLY MORE CLOUD COVER THAN YDY. 1 HR FFG AFTER YDYS RAINS ARE NOW IN THE 1.4-1.8 INCH RANGE FOR NW CHESTER...CENTRAL MONTGOMERY...PHL COUNTY IN PA...NW CAMDEN...CENTRAL BURLINGTON...MERCER...WARREN AND MORRIS COUNTIES IN NJ NEWD. NO FFA. FFW...SVR AND SMW'S WBIS AS NEED. TONIGHT...SHOWERS AND TSTMS DIMINISH SEWD DURING THE NIGHT WITH THE BIGGEST STORMS OVER DELMARVA. THEN FAIR OVERNIGHT WITH HAZE AND HUMIDITY. ABOVE NORMAL TEMPS. ONE CAVEAT...SOME OF OUR GUIDANCE IS TRYING TO DEVELOP BACK EDGE OF SHOWERS AND CLOUDS NEWD FROM DELMARVA ALONG THE COAST OVERNIGHT. ATTM WE OPTED FOR A DRIER EASTWARD SOLUTION. NEEDS REEVALUATION ON THE EVENING SHIFTS. NO FOG IN THE FCST ATTM SINCE I WAS WRONG ON ITS EXPECTATION EARLY THIS MORNING AND ITS JUST A SUMMER HUMID AIRMASS WITH SHORT NIGHTS. AS FOR TEMPERATURES, MOSTLY AN EVEN BLEND OF THE GFS/NAM MOS WAS USED. THE THINKING IS THESE TEMPS MAY BE 1-2F TOO COOL TONIGHT. && .SHORT TERM /6 AM SATURDAY MORNING THROUGH 6 PM SATURDAY/... SATURDAY...SHOULD BE BY AND LARGE RAINFREE OVER MOST OF THE AREA WITH THE EXCEPTION POSSIBLY OF THE COAST. DO NOT HAVE THUNDER IN THE FCST DUE TO LOWER DEWPOINTS...MUCH LESS MLCAPE. INSTABILITY IS MARGINAL. ITS POSSIBLE WE'LL NEED TO MIX IN SOME THUNDER ALONG THE COAST DURING THE AFTN BUT ATTM...NOT CONFIDENT OF ANY SHOWERS. 50 50 BLENDED 12Z/28 GFS/NAM MOS GUIDANCE FOR TEMPS/DEWS/WINDS. && .LONG TERM /SATURDAY NIGHT THROUGH FRIDAY/... AT THE SURFACE, HIGH PRESSURE WILL CONTINUE TO SIT OVER THE WESTERN ATLANTIC WHILE A STALLED FRONTAL BOUNDARY REMAINS ACROSS OR NEAR OUR AREA. IN THE MID-LEVELS, A CLOSED LOW WILL GRADUALLY OPEN WHILE PUSHING A DEEP TROUGH INTO THE OHIO VALLEY AND THEN INTO THE DEEP SOUTH INTO EARLY NEXT WEEK. THIS WILL KEEP US IN AN UNSETTLED PATTERN THROUGH THE EXTENDED PERIOD. THE HIGH STARTS TO RETROGRADE EARLY IN THE WEEK, WHICH SHOULD PUSH THE FRONTAL BOUNDARY WESTWARD. WITH THE BOUNDARY IN CLOSE PROXIMITY TO OUR AREA AND SEVERAL MID-LEVEL IMPULSES ROTATING THROUGH OUR AREA, WE WILL HAVE A CHANCE FOR SHOWERS AND THUNDERSTORMS NEARLY EVERY DAY. AS THE HIGH PUSHES WESTWARD, THE FRONT STARTS TO BREAK DOWN AND SHOULD START TO DISSIPATE IN THE MID TO LATE WEEK TIMEFRAME. PRECIPITABLE WATER VALUES WILL REMAIN HIGH, AROUND 2 INCHES, AS WE CONTINUE TO HAVE DEEP SOUTHWESTERLY FLOW INTO THE REGION. HEAVY RAIN WILL CONTINUE TO BE A THREAT WITH ANY STORMS THAT DEVELOP AND WITH CONSIDERABLE RAIN SO FAR THIS MONTH ACROSS THE REGION, THE POTENTIAL FOR FLOODING WILL REMAIN A CONCERN. MONDAY LOOKS LIKE IT WILL BE ONE OF THE BETTER DAYS FOR HEAVY RAIN TO OCCUR AS THE FRONT IS FORCED WEST AND THE GRADIENT TIGHTENS. THIS WILL INCREASE THE SOUTHERLY FLOW ACROSS THE REGION. HOWEVER, THE UNCERTAINTY IN THE PLACEMENT OF THE DECAYING FRONT MAKES ZEROING IN ON THE AXIS OF HEAVIEST PRECIPITATION DIFFICULT BUT IT CONTINUES TO LOOK LIKE HEAVY RAIN WILL FALL ACROSS AT LEAST PARTS OF OUR AREA ON MONDAY. SKIES WILL HAVE A FAIR AMOUNT OF CLOUDS EACH DAY, WHICH SHOULD HELP TO LIMIT SURFACE HEATING TO A CERTAIN DEGREE. MAXIMUM TEMPERATURES ARE EXPECTED TO BE NEAR NORMAL, WHILE MINIMUM TEMPERATURES ARE MORE LIKELY TO BE SLIGHTLY ABOVE NORMAL. && .AVIATION /20Z FRIDAY THROUGH WEDNESDAY/... THE FOLLOWING DISCUSSION IS FOR KPHL, KPNE, KTTN, KABE, KRDG, KILG, KMIV, KACY AND SURROUNDING AREAS. REMAINDER OF TODAY...SCT-BKN CLOUDS AOA 4000 FT THIS AFTN WITH SW G 20 KT. WINDS HAVE BRIEFLY BACKED A LITTLE MORE THAN EXPECTED IN MY 18Z TAF. WILL MONITOR AT 19Z FOR A POSSIBLE MORE SLY CONVERGENT FLOW AHEAD OF THE TSTMS. BRIEF IFR VSBY TSTMS IN THE TAFS WHERE MOST CONFIDENT ALONG WITH GUSTS. HIGH CONFIDENCE FOR TSTM EVENT KPHL AREA BETWEEN 20Z-24Z....GUST IS 34 KT BUT NOT IMPOSSIBLE TO SEE G45KT KPHL KILG. PLEASE MONITOR STORM DEVELOPMENT AND TAF UPDATES. TONIGHT...AREAS OF SUB-VFR MAINLY DUE TO SHOWERS AND THUNDERSTORMS, WHICH ARE ANTICIPATED TO WEAKEN DURING THE EVENING HOURS. OTHERWISE, MOSTLY VFR ALTHOUGH SOME LOCAL FOG MAY DEVELOP ESPECIALLY LATE. SOUTHWEST WINDS DIMINISHING TO NEAR 5 KNOTS. SATURDAY...GENERALLY VFR SCT-BKN CLOUDS AOA 4000 FT EXCEPT POSSIBLE MVFR HAZE TIL 14Z. LOW CONFIDENCE ON FCSTG ANY AFTN SHOWERS...AND HAVE THESE RESTRICTED MAINLY TO THE COAST AND POCONOS. OUTLOOK... SATURDAY NIGHT THROUGH WEDNESDAY...GENERALLY VFR CONDITIONS EXPECTED. PERIODS OF MVFR/IFR IN SHOWERS AND THUNDERSTORMS MAINLY DURING THE AFTERNOON/EVENING HOURS. MVFR/IFR IN MORNING STRATUS/FOG IS POSSIBLE AS WELL. && .MARINE... ATLC SEAS SCA CONTINUES. ITS MARGINAL AND GFS WW3 GUIDANCE HAS BEEN TOO HIGH AND STILL IS! WE TRIMMED THE 12Z/28 GFS WW3 GUIDANCE AND SWELLS BY 1 FOOT THROUGH SATURDAY. OUTLOOK... HIGH PRESSURE REMAINS ANCHORED TO OUR EAST THROUGH MUCH OF NEXT WEEK. IN ADDITION, THERE WILL BE A FRONTAL BOUNDARY STALLED ACROSS OUR AREA. THE FLOW BETWEEN THE HIGH AND THE FRONT WILL BE OUT OF THE SOUTH OR SOUTH-SOUTHWEST. WINDS WILL BECOME GUSTY, ESPECIALLY ACROSS THE NORTHERN WATERS AS THIS FLOW CONTINUES THROUGH THE WEEK AND GUSTS AROUND 25 TO 30 KNOTS CAN BE EXPECTED. SEAS WILL GRADUALLY INCREASE AND WITH NO CHANGE IN THE SURFACE FLOW, THE SOUTHERLY FETCH WILL LIKELY KEEP SEAS AROUND 5 TO 7 FEET THROUGH AT LEAST MIDWEEK. && .RIP CURRENTS... THERE IS A MODERATE RISK OF DANGEROUS RIP CURRENTS FOR THE NEW JERSEY AND DELAWARE COASTS TODAY INTO TONIGHT. THIS IS BASED MAINLY ON SOME HIGHER SURF AND ALSO A SOMEWHAT LONGER PERIOD SWELL CONTRIBUTION. && .CLIMATE... WARMER THAN NORMAL DAILY TEMPS FOR AT LEAST THE NEXT 10-14 DAYS... (JULY 10TH FOR NOW) AS A PERSISTENT HUMID SSW SFC FLOW PREVAILS... PER 00Z/28 NAEFS AND 00Z/28 RMOP. A STAUNCH WESTERN ATLC RIDGE DEVELOPS AND BUILDS WESTWARD AND THEN MAY EMERGE OVER THE SE USA BY JULY 8TH...WHICH IF OCCURS...RETURNS 90F HEAT TO OUR AREA AS THE SSW FLOW TURNS MORE SW OR WSW. EC AND GFS MODEL TEMP GUIDANCE IS IN AGREEMENT THE NEXT 7 DAYS WITH TEMPS AVG'G 2 TO 6 DEGS ABOVE NORMAL ON A DAILY BASIS...THE GREATEST DEPARTURES OCCURRING WITH NIGHTTIME LOWS BEING SIGNIFICANTLY ON THE WARM SIDE OF NORMAL...AVERAGING ABOUT 5 DEGS WARMER THAN NORMAL NIGHTLY. THIS IS THE RESPONSE TO HIGH DEWPOINTS PREVENTING DECENT RADIATIONAL COOLING. JUNE TEMPERATURES WILL AVERAGE ABOVE NORMAL FOR ALL STATIONS ON THE ORDER OF GENERALLY 1 TO 2 DEGREES...MAYBE MORE THAN 2 DEGS ABOVE NORMAL AT KRDG AND KGED.
