The episode as NWS PHI wrote it up.
A weakening approaching cold front triggered a series of strong to severe thunderstorms during the late afternoon and into the middle of the evening in New Jersey. Hardest hit was Hunterdon County with multiple municipalities that reported downed trees and wires.

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MOUNT HOLLY NJ
408 PM EDT WED JUL 2 2014
.SYNOPSIS...
A TROUGH OF LOW PRESSURE TO THE WEST WILL AFFECT OUR REGION TONIGHT.
IT WILL BE FOLLOWED BY A COLD FRONT WHICH WILL THEN CROSS THE AREA
THURSDAY INTO FRIDAY. BY THURSDAY...TROPICAL STORM ARTHUR WILL START
MOVING NORTHEAST AND WILL INTERACT WITH THE FRONT OFFSHORE BY LATE
FRIDAY AND SATURDAY. ANOTHER HIGH PRESSURE SYSTEM WILL MOVE TOWARD
OUR AREA BY SUNDAY BEFORE MOVING EAST OF THE REGION EARLY NEXT WEEK
&&
.NEAR TERM /UNTIL 6 AM THURSDAY MORNING/...
CONVECTION WAS OCCURRING IN BERKS COUNTY, THE LEHIGH VALLEY, THE
POCONOS AND NORTHWESTERN NEW JERSEY AT MID AFTERNOON. THE ATMOSPHERE
REMAINS QUITE UNSTABLE WITH SURFACE BASED CAPE VALUES IN EXCESS OF
3000 J/KG IN MUCH OF OUR REGION. A SEVERE THUNDERSTORM WATCH REMAINS
IN EFFECT UNTIL 700 PM FOR OUR NORTHWESTERN COUNTIES AND UNTIL 900
PM FOR THE REST OF OUR FORECAST AREA. THE STORMS ARE RELATIVELY SLOW
MOVING AND PRECIPITABLE WATER VALUES ARE IN EXCESS OF 1.75 INCHES.
AS A RESULT, LOCALLY HEAVY RAINFALL IS LIKELY.
HEAT INDEX VALUES HAVE EXCEEDED 100 IN MUCH OF OUR HIGHLY URBANIZED
CORRIDOR FROM WILMINGTON TO PHILADELPHIA TO TRENTON. THE HEAT
ADVISORY WILL REMAIN IN EFFECT UNTIL 800 PM. THUNDERSTORMS SHOULD
REACH THE INTERSTATE 95 CORRIDOR BY THAT TIME, COOLING TEMPERATURES.
A MOSTLY CLOUDY SKY ALONG WITH PATCHY LIGHT FOG AND HAZE ARE
EXPECTED FOR OVERNIGHT. SCATTERED RAIN SHOWERS MAY LINGER. LOW
TEMPERATURES SHOULD BE MAINLY IN THE LOWER AND MIDDLE 70S WITH A
LIGHT WIND.
&&
.SHORT TERM /6 AM THURSDAY MORNING THROUGH 6 PM THURSDAY/...
WE ARE ANTICIPATING THE FRONTAL BOUNDARY FROM THE NORTHWEST TO STALL
OVER OUR REGION ON THURSDAY. IT IS EXPECTED TO BEGIN TO INTERACT
WITH TROPICAL MOISTURE WHICH HAS BECOME ESTABLISHED IN OUR REGION.
AS A RESULT, WE ARE ANTICIPATING SHOWERS AND SCATTERED THUNDERSTORMS
TO DEVELOP ON THURSDAY MORNING AND THEY SHOULD CONTINUE INTO THE
AFTERNOON. PRECIPITABLE WATER VALUES WILL BE AROUND 2 INCHES. THE
SHOWERS AND THUNDERSTORMS SHOULD BE SLOW MOVING AND WE ARE CONCERNED
WITH THE POTENTIAL FOR FLASH FLOODING FROM THE INTERSTATE 95
CORRIDOR NORTHWESTWARD. WE HAVE ISSUED A FLASH FLOOD WATCH FOR THOSE
AREAS.
WE HAVE GONE A BIT BELOW GUIDANCE FOR THE MAXIMUM TEMPERATURES FOR
THURSDAY DUE TO THE EXPECTED RAIN SHOWERS AND CLOUD COVER. THE WIND
SHOULD FAVOR THE SOUTH AND SOUTHWEST AROUND 5 TO 10 MPH.
&&
.LONG TERM /THURSDAY NIGHT THROUGH WEDNESDAY/...
AT THE START OF THE LONGTERM PERIOD THE MID-LEVEL TROUGHING WILL
STILL BE TO THE WEST OF THE REGION. THIS WILL ALLOW FOR THE SURFACE
COLD FRONT TO SLOWLY SLINK ACROSS THE REGION AS IT BECOMES BETTER
ALIGNED PARALLEL TO THE UPPER LEVEL FLOW AS TS ARTHUR IS EXPECTED
TO PASS WELL TO OUR EAST. THE TROUGHING SHOULD LIFT THROUGH BY THE
FIRST HALF OF THE WEEKEND GIVING WAY TO PSEUDO-ZONAL FLOW THROUGH
EARLY NEXT WEEK. ANOTHER DEEPENING TROUGH IS EXPECTED BY MID NEXT
WEEK.
FRIDAY...THIS IS THE TIME OF THE YEAR WHERE WE HARDLY SEE A ROBUST
COLD FRONT RIP THROUGH THE REGION GIVING WAY TO A MORE REFRESHING
AIRMASS. AS PER THE NORM, THE SURFACE BOUNDARY WILL BASICALLY LIMP
THROUGH LATER ON FRIDAY PROVIDING ANOTHER FOCUS FOR CONVECTION AS
PWATS REMAIN AROUND 2 INHCES...MORE HEAVY RAIN IS EXPECTED. AT THIS
TIME THE CURRENT TRACK OF TS ARTHUR MAKES ITS CLOSEST PASS OF OUR
REGION, STILL WELL OFFSHORE, AS IT RACES TOWARDS THE NORTHEAST SO
DIRECT IMPACTS FROM THE SYSTEM WILL BE MINIMAL, WITH SOME MOISTURE
ENHANCEMENT AHEAD OF THE COLD FRONT.
SATURDAY - SUNDAY...HIGH PRESSURE AND NORTHWEST WINDS WILL BE IN
PLACE WITH LOWERING DEWPOINTS AND TEMPERATURES. EXPECTING DRY
WEATHER FOR THE WEEKEND WITH TEMPERATURES RIGHT AROUND AVERAGE.
MONDAY...HIGH PRESSURE MOVES OFFSHORE AND A RETURN FLOW SETS UP SO
WE WILL SEE A RETURN TO THE HEAT AND HUMIDITY. MEDIUM RANGE GUIDANCE
DIFFERS A BIT ON HOW FAST THE BOUNDARY LAYER MOISTENS UNDER THE WARM
AIR/THETA-E ADVECTION TAKING PLACE. THE TIMING OF THE NEXT MID-LEVEL
IMPULSE IS ALSO SUSPECT WITH THE GFS MUCH WETTER THAN THE EURO. FOR
THE TIME BEING USED A BLEND OF PERSISTENCE AND WPC GIVING A CHANCE
FOR SHOWERS ACROSS OUR NORTHERN TIER ZONES.
TUESDAY - WEDNESDAY...PRE-FRONTAL HEAT TROUGHS BOTH AFTERNOONS
SHOULD BE ENOUGH OF A FOCUS FOR SCATTERED SHOWERS AND THUNDERSTORMS
AHEAD OF THE NEXT COLD FRONT. THE NEXT FRONT IS EXPECTED TO
CROSS/STALL ACROSS THE REGION ON WEDNESDAY WITH CONTINUED SHOWERY
ACTIVITY. TEMPERATURES SHOULD BE WELL ABOVE NORMAL.
&&
.AVIATION /20Z WEDNESDAY THROUGH MONDAY/...
THE FOLLOWING DISCUSSION IS FOR KPHL, KPNE, KTTN, KABE, KRDG, KILG,
KMIV, KACY AND SURROUNDING AREAS.
THUNDERSTORMS WILL CONTINUE TO MAKE THEIR WAY EASTWARD ACROSS OUR
FORECAST AREA DURING THE BALANCE OF THE AFTERNOON AND EVENING HOURS.
WHILE CONDITIONS WILL BE MOSTLY IN THE VFR CATEGORY, THE
THUNDERSTORMS WILL BE ACCOMPANIED BY IFR CONDITIONS ALONG WITH
FREQUENT LIGHTNING, GUSTY WINDS AND HEAVY RAIN.
THE THUNDERSTORM ACTIVITY SHOULD LESSEN FOR THE OVERNIGHT PERIOD
WITH LINGERING CLOUDS AND SHOWERS ANTICIPATED. CONDITIONS SHOULD BE
MOSTLY VFR WITH OCCASIONAL MVFR CEILINGS AND VISIBILITY VALUES.
SHOWERS AND SCATTERED THUNDERSTORMS ARE FORECAST TO DEVELOP ON
THURSDAY MORNING AND THEY SHOULD CONTINUE THROUGH THE AFTERNOON.
CONDITIONS MAY DETERIORATE AS THE DAY PROGRESSES. THE RAIN WILL
LIKELY BE HEAVY AT TIMES.
THE WIND SHOULD FAVOR THE SOUTH AND SOUTHWEST AROUND 8 TO 10 KNOTS
INTO THIS EVENING. A LIGHT AND VARIABLE WIND IS EXPECTED FOR
OVERNIGHT. A SOUTH TO SOUTHWEST WIND AROUND 8 TO 10 KNOTS IS
FORECAST FOR THURSDAY.
OUTLOOK...
FRIDAY...MOSTLY POOR CONDITIONS WITH CIG/VSBY RESTRICTIONS AND OCNL
SHOWERS/TSTMS. GUSTY NORTH-NORTHWEST WINDS LIKELY.
FRIDAY NIGHT THRU SUNDAY...MOSTLY VFR. GUSTY WINDS SAT.
MONDAY...VFR. POSSIBLE AFTERNOON SHOWERS/THUNDERSTORMS NORTH OF PHL.
&&
.MARINE...
A SOUTHERLY FLOW IS EXPECTED ON THE COASTAL WATERS OF NEW JERSEY AND
DELAWARE FOR TONIGHT AND THURSDAY. SPEEDS SHOULD BE MAINLY IN THE 10
TO 20 KNOT RANGE.
WE WILL ALLOW THE SMALL CRAFT ADVISORY FOR THE WATERS TO CONTINUE
UNTIL 1000 PM FOR THE POTENTIAL OF 25 KNOT WIND GUSTS. OTHERWISE,
WIND SPEEDS AND WAVE HEIGHTS SHOULD BE BELOW THE SMALL CRAFT
ADVISORY CRITERIA FOR TONIGHT AND THURSDAY.
OUTLOOK...
FRIDAY...MARINE HEADLINES EXPECTED MUCH OF THE PERIOD
WITH THE INFLUENCE OF ARTHUR PASSING EAST OF THE WATERS.
SAT THRU MON...SCA SEAS EARLY SAT THEN SUB-SCA THRU MON.
&&
.HYDROLOGY...
WE HAVE DECIDED TO ISSUE A FLASH FLOOD WATCH FOR THE I-95 CORRIDOR
AND ALL POINTS WESTWARD BETWEEN 12Z THURSDAY AND 16Z FRIDAY.
REASONS...SLOW MOVING SURFACE FRONT, 2.00" PW'S AHEAD AND ALONG THE
FRONT, AMPLE INSTABILITY, PRONOUNCED UPPER LEVEL DIVERGENCE, AND THE
POSSIBILITY OF A PREDECESSOR RAINFALL EVENT OR PRE.
TIMING...WHILE AN ABOVE INGREDIENT OR TWO ARE IN PLACE AT SOME TIME
TEMPORALLY WITHIN THE WATCH, THEY ALL COME TOGETHER TOMORROW
AFTERNOON INTO TOMORROW EVENING. DURING THIS TIME, THE PW'S PEAK
AROUND 2.00" AND THE RIGHT REAR QUAD OF THE H25 JET IS OVERHEAD.
PREDECESSOR RAINFALL EVENTS (PRE)...AT THE MOMENT, THE GENERAL QPF
CONSENSUS FOR THE REGION IS BETWEEN ONE TO THREE INCHES OF RAINFALL,
FALLING TOMORROW INTO FRIDAY MORNING. THAT SAID, IS IT KNOWN THAT
NWP MODELS CAN UNDERESTIMATE HEAVY RAINFALL ASSOCIATED WITH A PRE.
DO WE HAVE PRE INGREDIENTS? YES WE DO. THIS INCLUDES THE RIGHT REAR
UPPER JET, BEING AHEAD OF THE MEAN LONG-WAVE TROUGH AXIS AT THE
MID-LEVELS, AND NEAR OR JUST WEST OF A LOW-LEVEL THETA-E RIDGE AXIS.
ADDITIONALLY, IF YOU LOOK AT THE CLIMATOLOGY OF PRE'S, MORE OF THEM
ARE TO THE LEFT OF A CYCLONE TRACK.
ALL OF THE ABOVE, AT LEAST AT THIS TIME, SEEM TO BE COMING TOGETHER
OVER SOUTHEAST PA. THIS IS WHY WE ARE PAINTING THE WATCH ACROSS THE
I-95 CORRIDOR AND POINTS TO THE WEST.
ANOTHER CONCERN IS THAT THE RIDGING RIGHT TO THE WEST OF ARTHUR
COULD SLOW THE APPROACHING FRONT DOWN EVEN MORE THAN WHAT MODELS ARE
CURRENTLY SUGGESTING.
ON A POSITIVE NOTE, ONE OF THE MORE TYPICAL INGREDIENTS WE COMMONLY
SEE IN LARGE RAIN EVENTS ACROSS THE FALL LINE IS A PERSISTENT
SOUTHEAST FLOW WITH AN EXTENDED FETCH. IN THIS CASE, WE ARE NOT
SEEING THAT, ALTHOUGH THE WINDS SHOULD GO SOUTHEAST RIGHT AHEAD OF
THE FRONT AND THE BEST SURFACE CONVERGENCE.
RAINFALL...1.00 TO 3.00", BUT WITH PW'S AROUND 2.00" CAN DEFINITELY
SEE 4.00", MAYBE 5.00" IN SOME ISOLATED SPOTS.
FLOODING...WE ARE NOT EXPECTING FLOODING ON ANY MAINSTEMS AT THIS
TIME. OUR CONCERN LIES WITH THE SMALLER CREEKS AND STREAMS ACROSS
SOUTHEAST PA AND NORTHERN DELAWARE AS WELL AS URBAN OR POOR DRAINAGE
AREAS.
&&
.RIP CURRENTS...
AN INCREASE IN RIP CURRENT RISK LIKELY THIS WEEKEND AS TROPICAL
STORM ARTHUR MOVES ALONG THE EAST COAST. THE RISK OF RIP CURRENTS
WILL BE AT LEAST MODERATE IF NOT HIGH DURING THE HOLIDAY WEEKEND GIVEN
THE LATEST NHC FORECAST. THIS POSES A HUGE CONCERN CONSIDERING THE
LARGE NUMBERS OF PEOPLE, INCLUDING THE LESS EXPERIENCED SWIMMERS,
WHO WILL VENTURE OUT DURING ONE OF THE BIGGEST BEACH WEEKENDS OF
THE YEAR. THE TRANQUIL WEATHER CONDITIONS ON LAND THIS WEEKEND
COULD LEAD TO A FALSE SENSE OF SAFETY IN THE WATERS.
RIP CURRENTS ARE LIFE-THREATENING IF YOU/RE NOT PREPARED TO
HANDLE THEM. FOR THE GREATEST CHANCE OF SAFETY...SWIM ONLY UNDER
THE WATCHFUL EYES OF LIFEGUARDS. OTHERWISE ANY OPPORTUNITY FOR
RESCUE CAN SUFFER FROM A MUCH GREATER RESPONSE DELAY AND BE FATAL.
