A nearly stationary frontal boundary and a low pressure system moving along it combined to develop thunderstorms that produced isolated damaging wind gusts as well as more widespread flash flooding across the southern half of New Jersey during the afternoon and evening of June 1st. As both the low pressure system and frontal boundary sagged southeast, the severe and heavy rain threat ceased.

The episode as NWS PHI wrote it up.
A nearly stationary frontal boundary and a low pressure system moving along it combined to develop thunderstorms that produced isolated damaging wind gusts as well as more widespread flash flooding across the southern half of New Jersey during the afternoon and evening of June 1st. As both the low pressure system and frontal boundary sagged southeast, the severe and heavy rain threat ceased.
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 Jun 1, 10:30 AM EST, 4 hours 10 minutes earlier.
AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MOUNT HOLLY NJ
1130 AM EDT MON JUN 1 2015
.SYNOPSIS...
THE COLD FRONT WILL CONTINUE TO SLOWLY SLIDE SOUTH THROUGH OUR
REGION TODAY AND TOMORROW. HIGH PRESSURE WILL BUILD SOUTHEASTWARD
BEHIND FOR THE MIDDLE AND LATTER HALF OF NEXT WEEK. THIS HIGH WILL
BE FOLLOWED BY ANOTHER COLD FRONT DROPPING SOUTHEAST INTO THE REGION
BY NEXT WEEKEND.
&&
.NEAR TERM /UNTIL 6 PM THIS EVENING/...
CURRENTLY WE HAVE A FRONTAL BOUNDARY LOCATED ACROSS THE CENTRAL
PORTIONS OF THE FORECAST AREA ACROSS EASTERN PA AND CENTRAL NJ. TO
THE NORTH OF THE BOUNDARY NORTHEAST WINDS AND RESIDUAL MOISTURE
HAVE LED TO A THICK LOW CLOUD DECK AND COOLER TERMEPRATURES.A
SUNNY SUMMER LIKE DAY IS IN PROGRESS SOUTH OF THE FRONT. THE HRRR
APPEARS TO HAVE A GOOD HANDLE OF THE FRONTAL LOCATION AND WAS USED
FOR TEMPERATURES THIS AFTERNOON. SUNNY REGIONS IN THE DELMARVA
WILL GO WELL INTO THE 80'S WITH AREAS FROM NORTHEAST PA INTO
NORTHERN NJ STAYING INTO THE 60'S.
ATTENTION TURNS TO WHERE SHOWERS AND STORMS WILL FORM ALONG THE
FRONT LATER TODAY. SEVERAL WRF'S THE HRRR AND RAP ALL SUGGEST
NARROW BANDS OF VERY HEAVY RAINFALL WITH THUNDERSTORMS SIMILAR TO
YESTERDAY. THE CHALLENGE OF TODAY'S FORECAST IS WHERE DOES IT SET
UP? OUR THINKING IS THE MOST LIKELY LOCATIONS ARE ACROSS SOUTHEAST
PA NEAR PHL INTO SOUTH- CENTRAL NJ. THE LATEST FEW HRRR RUNS ALSO
EXPAND THE HEAVIEST AXIS OF RAIN INTO DELAWARE. THE FLASH FLOOD
WATCH HAS BEEN EXPANDED SOUTHEAST FOR THIS POTENTIAL.
&&
.SHORT TERM /6 PM THIS EVENING THROUGH 6 AM TUESDAY/...
MUCH LIKE THIS MRNG, WE CUD BE LOOKING AT LESS OF A
CONVECTIVE THREAT AND MORE OF A STEADY RAIN THREAT, AGAIN DEPENDING
ON WHERE THE FRONT IS LOCATED. BY TONIGHT, IT SHUD BE THRU THE I-95
CORRIDOR AND SLOWLY WORKING S. PRECIP AMTS SHUD BE LIGHTER DURG THE
NIGHTTIME HOURS.
&&
.LONG TERM /TUESDAY THROUGH SUNDAY/...
DID NOT MAKE MANY CHANGES TO THE LONG TERM, SO FOCUS COULD BE ON
THE ONGOING CONVECTION.
TUESDAY...FRONT CONTINUES ITS PROGRESS SOUTH AT A SNAILS PACE.
PRECIPITATION MAY LINGER, ESPECIALLY TUESDAY MORNING, NORTH OF
THE FRONT DUE TO WEAK ON SHORE LOW LEVEL FLOW. BUT EXPECT MOSTLY
LIGHT RAIN DUE TO INCREASING STABILITY.
WEDNESDAY THROUGH FRIDAY: HIGH PRESSURE BUILDS OVER THEN PASSES EAST
OF THE REGION FOR THE MIDDLE AND LATER HALF OF THE WEEK. COOL
REFRESHING AIRMASS TO START THEN WARMER AND MUGGY BY WEEKS END. THE
POTENTIAL STILL DOES EXIST FOR AN AREA OF LOW PRESSURE TO DEVELOP WELL
TO OUR SOUTHEAST NEAR THE FRONTAL BOUNDARY WHICH PASSES THROUGH
OUR REGION TUESDAY. RIGHT NOW FOR THIS TIMEFRAME IT STILL LOOKS
LIKE THE HIGH PRESSURE HAS ENOUGH PUSH TO KEEP OUR WEATHER PARTLY
TO MOSTLY CLOUDY WITH THE MOST CLOUDS ACROSS THE SOUTHERN DELMARVA
REGION. A FEW SHOWERS AND STORMS MAY BE POSSIBLE ON FRIDAY AS THE
HIGH BEGINS TO BREAK DOWN, BUT STILL CONSIDERABLE UNCERTAINTY.
FRIDAY NIGHT THROUGH SUNDAY: ANOTHER COLD FRONT IS LIKELY TO MOVE
INTO THE REGION POSSIBLY DECAYING OVER THE REGION. TIMING
DIFFERENCES AS USUAL ARE PRESENT WITH THIS FEATURE WITH THE
FASTER, STRONGER GFS AND THE SLOWER ECMWF. WARM AND MORE HUMID
CONDITIONS ARE LIKELY PRECEDE THE FRONT. SOME SCATTERED
THUNDERSTORMS MAY FORM AHEAD OF THE FRONT AS WELL. OPTED FOR LOW
CHANCE POPS ATTM CENTERED ON SATURDAY AFTERNOON AND EVENING,
CLOSER TO THE ECMWF TIMING. GIVEN THE UNCERTAINTY WITH THE
FRONTAL TIMING AND THE POTENTIAL FOR MORE CLOUDS, KEPT
TEMPERATURES FAIRLY CLOSE TO THE GFS/ECMWF/WPC ENSEMBLE SETS.
&&
.AVIATION /16Z MONDAY THROUGH FRIDAY/...
THE FOLLOWING DISCUSSION IS FOR KPHL, KPNE, KTTN, KABE, KRDG, KILG,
KMIV, KACY AND SURROUNDING AREAS.
A FRONTAL BOUNDARY IS ROUGHLY LOCATED FROM RDG TO PHL FURTHER
EAST. ALONG AND NORTH OF THE BOUNDARY NORTHEAST WINDS UNDER 10
KNOTS HAS BROUGHT IN A IFR CLOUD DECK WHICH LOOKS TO HOLD FIRM
INTO THE EARLY AFTERNOON. THE SOUTHERN EDGE OF THE CLOUDS RUNS
FROM ILG TO MIV AND ACY WHERE CONDITIONS MAY GO BACK AND FORTH
BETWEEN IFR AND EVEN VFR THROUGH INTO THE AFTERNOON.
SHOWERS AND THUNDERSTORMS ARE LIKELY TO DEVELOP ALONG THE FRONT
THIS AFTERNOON STARTING BETWEEN 16 AND 18Z FROM PHL AND POINTS TO
THE SOUTH AND EAST.
OUTLOOK...
TUESDAY...IMPROVING TO VFR AS SHOWERS AND STORMS MOVE SOUTH OF THE
TAF SITES.
WEDNESDAY THROUGH FRIDAY...GENERALLY VFR CONDITIONS. A FEW STORMS
POSSIBLE ON FRIDAY.
&&
.MARINE...
NO MARINE FLAGS ARE ANTICIPATED THRU THE NR AND SHORT TERM
PDS, WITH SEAS GENLY 3 TO 4 FT AND WIND GUSTING AROUND 20 KT OUTSIDE
OF ANY TSRA.
OUTLOOK...
TUESDAY...WINDS AND SEAS SHOULD REMAIN BELOW SCA CRITERIA.
WEDNESDAY THROUGH THURSDAY...A FEW GUSTS NEAR OR ABOVE 20 KT ARE
POSSIBLE, PRIMARILY ON THE OCEAN WATERS. IN ADDITION...SEAS MAY BE
AROUND 5 FT, BUT THERE IS CONSIDERABLE UNCERTAINTY.
FRIDAY...WINDS AND SEAS SHOULD REMAIN BELOW SCA CRITERIA.
&&
.RIP CURRENTS...

SHORE AND DELAWARE BEACHES TODAY.
