The episode as NWS PHI wrote it up.
Widely scattered pulse type strong to severe thunderstorms affected the local Philadelphia area during the late afternoon of the 25th. PECO Energy reported about 5,000 homes and businesses lost power. Then later at night, a weakening line of strong to severe thunderstorms caused wind damage west of Philadelphia.
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 25, 2:34 PM EST, 1 hour 1 minute earlier.
AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MOUNT HOLLY NJ
334 PM EDT TUE JUN 25 2013
.SYNOPSIS...
A BERMUDA HIGH PRESSURE SYSTEM WILL KEEP THE REGION LOCKED IN A
HOT AND HUMID AIRMASS THROUGH AT LEAST THURSDAY. A STRONG COLD
FRONT WILL APPROACH FROM THE WEST ON THURSDAY AND CROSS THE AREA
BY FRIDAY BEFORE STALLING OFF THE COAST. AS A RESULT A PERIOD OF
UNSETTLED WEATHER IS EXPECTED FOR THE START OF JULY.
&&
.NEAR TERM /UNTIL 6 AM WEDNESDAY MORNING/...
NEITHER OF THE MODELS 500MB ANALYSIS LOOKED SPOT ON IN THE MIDWEST
AS THE SERIES OF CONVECTIVE COMPLEXES CONTINUE TO CAUSE
INITIALIZATION ISSUES. IF ANYTHING THE SYSTEMS LOOK SLIGHTLY SLOWER
THAN MODELED. THERMALLY A GFS AND WRF-NMMB COMPROMISE WORK THE BEST.
BUT THEY DIVERGE RATHER QUICKLY AFTER THAT.
INTO THIS EVENING SCATTERED THUNDERSTORMS WILL CONTINUE TO MOVE
THROUGH OUR CWA. IN GENERAL THE THERMODYNAMIC AND KINEMATIC
ENVIRONMENT IS NOT ON THE LEVEL OF YESTERDAY. SO FAR THE ORIENTATION
HAS BEEN MORE NORTH THAN SOUTH AND HIEST POPS WERE KEPT THERE.
WHILE ONE OR TWO PULSY TYPE STORMS MIGHT REQUIRE WARNINGS THE
OVERALL WEAK FCST BULK SHEAR ALONG WITH POORER MID LEVEL LAPSE RATES
SHOULD KEEP THIS BELOW LEVELS OF YESTERDAY'S CONVECTION. SOME OF THE
12Z MESOSCALE MODELS (SPC WRF/NMM) WENT TOO MUCH THE OTHER WAY AND
SHOWING WAY TOO LITTLE. BEST FIT IS BETWEEN THE RAP AND SLIGHTLY
TONED DOWN HR3.
FARTHER UPSTREAM MORE CONVECTION IS FORECAST TO DEVELOP OVER THE
UPPER OHIO VALLEY. THIS ONE WILL HAVE SOME SHORT WAVE SUPPORT, BUT
GIVEN ITS ARRIVAL LATER IN THIS EVENING LOWERS CONFIDENCE LEVELS AS
TO SUSTAINABILITY. WE DID CARRY POPS THROUGH THE EVENING AND WE WILL
SEE HOW THE PRESENT DEVELOPMENT EVOLVES.
STAT GUIDANCE HAS BEEN PRETTY REASONABLE WITH MINS AND WE CONTINUE
TO FOLLOW A MET/MAV BLEND.
&&
.SHORT TERM /6 AM WEDNESDAY MORNING THROUGH 6 PM WEDNESDAY/...
WE WILL ISSUE A HEAT ADVISORY FOR URBAN AREAS FOR WEDNESDAY.
CONFIDENCE IS NOT THE GREATEST, BUT THIS WILL BE THE THIRD STRAIGHT
DAY OF 90 PLUS HEAT AND NOT SURE IF WE ARE GOING TO GET AS MUCH
COOLING FROM TSRAS TONIGHT AS LAST NIGHT. NAM MOS IS RUNNING
APPROXIMATELY 3-6F TOO LOW ON HOURLY TEMPS TODAY, SO GUIDANCE WAS
NOT USED ON WEDNESDAY. GFS MOS WHICH HAS VERIFIED BETTER MATCHES
PRETTY CLOSELY WITH FCST 850/925MB TEMPS AS WELL AS 1000-850
THICKNESSES. OF CONCERN ALSO HAS BEEN THAT STAT GUIDANCE HAS BEEN
MIXING DEW POINTS DOWNWARD TOO QUICKLY THE PAST TWO DAYS. WHETHER ITS
THE LEE SIDE TROF OR JUST HOW WET THIS JUNE HAS BEEN, NOT BANKING ON
THE THIRD TIME BEING THE CHARM. RIGHT NOW THIS APPEARS TO BE ONE
DAY EVENT REASON FOR ADVY VS WARNING.
SENSIBLE WEATHER, IF TODAY IS THE RELATIVE LULL IN CONVECTIVE
ACTIVITY, WEDNESDAY IS SHOWING A TICK UP. NEARLY ALL KINEMATIC AND
THERMODYNAMICALLY FORCINGS ARE SLIGHTLY STRONGER THAN TODAY. THE ONE
PROBLEM WE ARE SEEING WITH WEDNESDAY IS THE SPLIT BETWEEN THE BETTER
FORCING NORTHWEST AND THE GREAT INSTABILITY AND FCST MID LEVEL LAPSE
RATES SE. PLUS THE FACT THE MODELS MAY BE FAST WITH THE OVERALL
PROGRESSION WILL HAVE US KEEP POPS AS CHANCE. SPC SLIGHT RISK
NORTHWEST HALF OF OUR CWA IS A GOOD FIT AS THAT IS CLOSER PROXIMITY
TO FORCING WHICH SHOULD BE PLACE FOR A BETTER CHANCE OF
ORGANIZATIONAL LINE OR CLUSTER.
&&
.LONG TERM /WEDNESDAY NIGHT THROUGH TUESDAY/...
THE WARM AND STICK AMS WILL REMAIN IN PLACE WED NIGHT AND BY THU A
STRONG S/WV, AND LOW PRESSURE SYS WILL APPROACH FROM THE W. THE
CDFNT ASSOCD WITH THIS LOW WILL CROSS THE REGION BY FRI MRNG. WITH
DEW POINTS INCREASING ON THU IT WILL REMAIN VERY UNCOMFORTABLE
DESPITE MORE CLOUDS AND TEMPS A FEW DEGREES LOWER THAN ON WED.
WITH A DECENTLY ROBUST LOW (FOR LATE JUNE) AND CDFNT APPROACHING,
THU COULD BE THE BEST SHOT OF SHWRS AND TSTMS FOR THE WEEK. SPC
HAS ALREADY PLACED A GOOD PORTION OF THE AREA GENLY WEST OF
PHILADELPHIA IN A SLGT RISK.
THE CDFNT WILL CROSS THE REGION BY FRIDAY BUT REMAIN CLOSE
OFFSHORE. PRECIP CHCS WILL DECREASE AND FRIDAY COULD END UP BEING
DRY OR MOSTLY DRY. SWLY FLOW WILL THEN PREVAIL THRU THE WEEKEND
INTO NEXT WEEK AND THE FLOW WILL STRENGTHEN ANS THE TROF DEEPENS
TO THE W. THIS WILL KEEP UNSETTLED WX OVER THE AREA WITH CHCS OF
SHWRS AND TSTMS EACH DAY. THERE ARE NO SIGNIFICANT SYNOPTIC
FEATURE OF NOTE, BUT EACH DAY'S TSTM CHCS WILL BE PARTIALLY BASED
ON BOUNDARIES AND ANY S/WVS THAT MAY BE PASSING THRU THE FLOW,
WHICH EACH MDL WILL HANDLE DIFFERENTLY AND ARE DIFFICULT TO
DIAGNOSE AT THIS TIME SCALE. FOR NOW, WILL MAINTAIN LOW CHC POPS.
MON LOOKS LIKE THERE COULD BE A WK LOW SO WILL GO A TAD HIGHER
THERE, BUT CONFIDENCE REMAINS LOW ON PRECIP CHCS AND LOCATION IN
THE EXTENDD PD.
AFTER THU, TEMPS LOOK TO RETURN CLOSER TO NRML, BUT WILL LIKELY
REMAIN SLIGHTLY ABV THRU THE PD.
&&
.AVIATION /19Z TUESDAY THROUGH SUNDAY/...
THE FOLLOWING DISCUSSION IS FOR KPHL, KPNE, KTTN, KABE, KRDG, KILG,
KMIV, KACY AND SURROUNDING AREAS.
18Z TAFS ARE CARRYING A TEMPO GROUP FOR THUNDERSTORMS THIS AFTERNOON
WITH MVFR CONDITIONS FROM THE KPHL METRO AREA AIRPORTS NORTHWARD.
OTHERWISE PREVAILING VFR CONDITIONS EXPECTED THROUGH THIS EVENING
WITH POSSIBLY MVFR CONDITIONS LATE TONIGHT. THEN WE START ALL OVER
AGAIN ON WEDNESDAY.
THIS AFTERNOON BEST FORCING AND WHERE ONGOING CONVECTION IS BOTH
FAVOR THUNDERSTORMS AT NORTHERN AIRPORTS AND TERMINALS.
CONFIDENCE IS LESS TOWARD THE KPHL METRO AIRPORTS WHERE THEY
SHOULD BE MORE ISOLATED. CONFIDENCE WAS TOO LOW AT KACY AND KMIV
TO INCLUDE IN TAFS. OUTSIDE OF THAT, VFR CONDITIONS ARE FORECAST WITH
WEST TO SOUTHWEST WINDS AVERAGING AROUND 10 KT. SEA BREEZE FRONT
SHOULD NOT MAKE MUCH MOVEMENT OFF THE COAST. WE ARE NOT
FORECASTING IT TO REACH KACY.
THIS EVENING ORGANIZED THUNDERSTORMS DEVELOPING IN THE OHIO VALLEY
ARE NOT FORECAST TO REACH THE TERMINALS. LOWEST CONFIDENCE KRDG. WE
SHOULD JUST HAVE SOME OUTFLOW VFR MID AND HIGH LEVEL CLOUDS.
SOUTHWEST WINDS AVERAGING 5 TO 10 KTS.
OVERNIGHT WE CARRIED SOME MVFR CONDITIONS LATE AT THE FOGGIER MORE
OUTLYING TERMINALS. THIS MIGHT NEED SOME ADJUSTMENT BASED ON ANY
CONVECTION DIRECTLY AFFECTING THE AIRPORTS. WINDS SHOULD BE LIGHT.
A VFR MORNING IS FORECAST FOR ALL OF THE TERMINALS WITH CU BASED
CLOUDS DEVELOPING. WEST TO SOUTHWEST WINDS SHOULD INCREASE TO
AROUND 10 KTS AGAIN. THE SEA BREEZE FRONT WILL STRUGGLE TO GET OFF
THE COAST AGAIN, MAYBE EVEN MORE SO THAN TODAY. MORE WIDESPREAD
SHOWERS AND THUNDERSTORMS ARE FORECAST FOR LATER WEDNESDAY, SO WE
INCLUDED A PROB30 FOR KPHL AS A START.
OUTLOOK...
WED NIGHT INTO THU MORNING...MOSTLY VFR WITH SHORT PERIODS OF
SUB-VFR IN MORNING FOG AND/OR SCT SHOWERS/TSTMS. MD CONFIDENCE.
THU AFTERNOON THROUGH SAT...GENLY VFR. HOWEVER, THERE WILL BE
PERIODS OF MVFR/IFR (POSSIBLY PROLONGED ONES) IN MORNING LOW
CLOUDS AND FOG AND AREAS OF SHOWERS AND TSTMS. LOW CONFIDENCE.
&&
.MARINE...
THE RETURN FLOW BEHIND THE DEPARTING BERMUDA HIGH WILL KEEP A W/SW
WIND ACROSS THE WATERS TODAY AND TONIGHT. WINDS/SEAS WILL REMAIN
BELOW SCA CONDITIONS THRU THE PERIOD. FAIR WEATHER EXPECTED THIS
MORNING...FOLLOWED BY SCT SHOWERS/TSTMS THIS AFTERNOON AND EARLY
EVENING. FAIR WEATHER WILL RESUME LATER TONIGHT INTO WED MORNING.
SEAS ON THE OCEAN WILL BE AROUND 2-4 FT AND 1-2 FT OVER DEL BAY.
REMEMBER...WINDS AND WAVES WILL BE LOCALLY HIGHER IN TSTMS.
OUTLOOK...
SUB-SCA CONDITIONS ARE EXPECTED INTO THURSDAY MORNING. AFTER THAT
INCREASING SWLY FLOW MIGHT BRING SCA CRITERIA MAINLY FOR SEAS, MORE SO
THAN WINDS, TO THE OCEAN WATERS BEGINNING LATER THU AND PSBLY
CONTINUING INTO THE WKND. RIGHT NOW CONFIDENCE REMAINS LOWER
THAN AVERAGE THAT THIS WILL OCCUR AS WAVE WATCH GUIDANCE OFTEN IS
TOO BULLISH UNDER THESE REGIMES.
