What happened

The episode as NWS PHI wrote it up.

An unseasonably hot and one of the most humid air masses of the summer combined to produce afternoon hourly heat indices of between 100F to 105F. High temperatures themselves were in the lower to mid 90s. There was one heat related death within Philadelphia. High temperatures included 95 degrees in Reading (Berks County), 94 degrees at the Philadelphia International Airport, 92 degrees in Pottstown (Montgomery County) and 91 degrees in Doylestown (Bucks County) and the Lehigh Valley International Airport.

This latest hot spell solidified July 2012 as one of the hottest Julys on record in Pennsylvania. It was the 5th hottest July on record (dating back through 1895) with a statewide average temperature of 74.5 degrees. At the Philadelphia International Airport, the July monthly mean temperature of 81.8 degrees was the 3rd warmest on record and the 21 days in which the maximum temperature reached 90 degrees or higher tied 2011 and four other Julys for the greatest ever. The unseasonably hot July helped pave the way for the 5th warmest meteorological summer on record in Philadelphia with an average temperature of 78.0 degrees. It was also the seventh warmest July on record at the Lehigh Valley International Airport with an average temperature of 77.5 degrees, the fourth warmest July on record in Mount Pocono (Monroe County) with an average temperature of 71.5 degrees and the third warmest July on record in Reading (Berks County) with an average temperature of 79.5 degrees.

Area forecast discussion, Jul 26, 8:11 AM EST, 1 hour 49 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MOUNT HOLLY NJ
911 AM EDT THU JUL 26 2012

.SYNOPSIS...
A STRONG WARM FRONT WILL PUSH NORTHEASTWARD THROUGH OUR REGION LATER
THIS MORNING. LOW PRESSURE WILL SETTLE SLOWLY SOUTH ACROSS OUR AREA
LATE FRIDAY AND SATURDAY WITH ITS WEAK COLD FRONT MOVING SOUTH OF
DELMARVA LATE 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 PM THIS EVENING/...
**NEAR RECORD OR RECORD HEAT KGED KACY AND KILG TODAY AND SPC MDT
 RISK FOR A LARGE PTN OF PA, NJ AND NORTHERN DE**

SHOWERS AND THUNDERSTORMS CONTINUE TO DEVELOP AND PUSH THROUGH OUR
AREA THIS MORNING. THESE STORMS ARE MOVING FAIRLY QUICKLY AND ARE
MOVING TO THE EAST SOUTHEAST. SOME AREAS WILL PICK UP A QUICK TENTH
OF AN INCH UP TO A QUARTER OF AN INCH AS THESE STORMS ROLL
THROUGH.

HIGH RISK RIP CURRENTS NJ COAST.

A SUBSTANTIAL HEAT EVENT IS SLATED FOR THIS AFTERNOON FOLLOWED BY
SVR. ITS GOING TO FEEL A WORLD OF DIFFERENCE BETWEEN 5 AM THIS
MORNING AND 5 PM THIS AFTERNOON...POSSIBLY AS BAD AS ITS BEEN
INCLUDING JULY 18!

00Z/26 NAM/RGEM 2M TEMPS BLENDED 50 50 WITH THE 00Z/26 GFS/NAM
MOS WHICH FAVORED WARMER THAN ALL GUIDANCE IN RELATIVELY STG SW
FLOW HOT AIR ADVECTION. 06Z NAM AND GFS ARE SIMILAR TO THEIR 00Z
VERSIONS SO THE FCST SHOULD BE ON TRACK.

DEPENDING ON CLOUD COVER...SEVERAL OF THESE HEAT ADVISORY ZONES
MAY NEED AN UPGRADE TO A WARNING. FOR NOW...CONSERVATIVE DUE TO
CLOUD COVER UNCERTAINTY. COULD SEE SPOT 111'S IN SNJ MID AFTN AND
SPOT 113'S IN E MD S 2/3RDS DE.

THEN FOR CONVECTION...NOT QUITE SURE HOW IT ALL WORKS BUT IT APPEARS
FIRST ATTN SHIFTS NORTH DURING THE 19Z-02Z TIME FRAME... INTO THE
SPC MDT RISK AREA WHICH IS ALSO WHERE BLENDED NCEP GUIDANCE...
INCLUDING SREF...HAVE HIGHEST POPS...WITHIN THE 2 INCH PWAT
CORRIDOR.

SURFACE BASED CAPE VALUES ARE FORECAST TO RISE ABOVE 3000 J/KG
THIS AFTN AND ML CAPE TO AT LEAST 2400J. PLENTY OF SHEAR BOTH IN
THE 0-3 AND 0-6KM LAYER. TT 49-52 AND SWI NEAR -4C. SO WE HAVE THE
POCS INTO NNJ FOR THE PRD 19Z-01Z FOR SVR. 00Z/26 SPC WRF WAS ALSO
REVIEWED AND APPLIED.

ANOTHER AREA OF CONCERN I THINK IS CONVERGENCE ASSTD WITH A LEE
SIDE TROF IN E PA IN THE 22Z-03Z WHICH WOULD SHOVE SHORT LINES OF
SVR TSTMS BOWING EWD FROM SE PA THRU S NJ. THIS IS LOWER CONFIDENCE
AND HOTTER AIR SO THE HAIL MAY BE SMALLER. THIS IS WELL DEFINED IN
THE 00Z/26 SPC WRF. SHOULD BE BOWING SEGMENTS DEVELOPING OUT OF A
NNE-SSW AXIS FM ROUGHLY KSEG SWD TO NEAR KDCA IN THE 20-23Z TIME
FRAME AND SWEEPING EWD OFF THE S NJ/DE COASTS BETWEEN 03-05Z.

THERE IS MODEL UNCERTAINTY REGARDING HOW FAR SOUTH CONVECTION
DEVELOPS THIS AFTN. THE LEAST LIKELY REGION FOR ANY TSTMS IS FROM
TALBOT AND CAROLINE COUNTIES IN MD THRU SUSSEX COUNTY IN S DE. PLS
MONITOR SWOMCD'S...WATCHES/WARNINGS THROUGH THE DAY. LIGHTNING
STRIKES IN STORMS SHOULD BE SIGNIFICANT.

THE CLIMATE SECTION HAS THE RECORDS...CONTINGENT ON CLOUD CVR.

&&

.SHORT TERM /6 PM THIS EVENING THROUGH 6 AM FRIDAY/...
THIS EVENING...SEE THE CONVECTIVE DISCUSSION IN THE NEAR TERM
ABOVE.

LATE TONIGHT...MAY NOT BE MUCH IF ANY CONVECTION AFTER 06Z THOUGH
IT WILL REMAIN UNSTABLE...ESPECIALLY S NJ DE/MD. VERY WARM WHERE
TSTM COMPLEXES DONT RAIN OR CAST COOLING OUTFLOWS. LIKELY EVENING
POPS DROP TO SMALL CHANCE IN THESE AREAS OVERNIGHT.

&&

.LONG TERM /FRIDAY THROUGH WEDNESDAY/...
ON-GOING CONVECTION OVER THE NORTHERN TIER OF OUR CWA WILL CONTINUE
TO WANE THROUGH THE MORNING HOURS. THIS WILL MORE THAN LIKELY WORK
OVER THE ATMOSPHERE IN THESE AREAS ENOUGH TO ULTIMATELY PUSH THE
THREAT FOR CONVECTION FURTHER SOUTH INTO DELMARVA AND SOUTHERN NEW
JERSEY. MODELS CONTINUE TO SHOW AMPLE MID-LEVEL ENERGY TRYING TO
BURST THROUGH DURING THE AFTERNOON TOMORROW AHEAD OF THE LONGWAVE
MID-LEVEL TROUGH PASSAGE. A LEE-SIDE TROUGH WILL ALSO DEVELOP IN
CENTRAL MARYLAND AND NORTHERN VIRGINIA AND WILL MOVE ACROSS OUR
DELMARVA ZONES INCREASING CHANCES OF CONVECTIVE INITIATION DURING
PEAK HEATING. SHEAR VALUES ARE NOT NEARLY AS IMPRESSIVE AS THEY ARE
FOR TODAY AND WE LOSE A BIT OF SURFACE INSTABILITY SO MORE OF A
PULSE/MULTICELLULAR CONVECTIVE MODE TYPE OF DAY IS ON TAP.

SPEAKING OF HEATING, THE DIFFUSE SURFACE BOUNDARY THAT WILL PUSH
THROUGH DURING THE DAY FROM THE NORTHWEST WILL ALLOW THE WINDS TO
VEER. THIS WILL INTRODUCE SLIGHTLY DRIER AIR INTO OUR WESTERN ZONES
WITH A DOWNSLOPING WIND COMPONENT. TEMPERATURES ALOFT AND AT THE
SURFACE WILL STILL BE QUITE HOT, +19C AT 850MB EQUATING TO AROUND
93/94F AT THE SURFACE. ACROSS THE DELMARVA AREAS MOISTURE WILL POOL
IN THE LOW-LEVELS AND WITH A MORE SOUTHWESTERLY FLOW STILL, HEAT
INDEX VALUES MAY EXCEED 105F...ADVISORY CRITERIA. SINCE THERE IS
CURRENTLY AN ADVISORY UP FOR TODAY FOR THESE AREAS, WITH TOMORROW
NOT BEING AS CLEAR CUT IN REGARDS TO THE POSITION OF THE SURFACE
BOUNDARY, FELT IT PRUDENT NOT TO EXTEND THE HEADLINE FOR DELMARVA
AND SOUTHERN NEW JERSEY. ACROSS THE PHILADELPHIA METRO AREA THE
WARNING HAS BEEN PUSHED THROUGH 22Z FRIDAY AS HEAT INDEX VALUES WILL
BE NEAR, IF NOT EXCEEDING, 100F FOR A COUPLE OF HOURS...MAINLY
ALONG THE I-95 CORRIDOR.

THE SURFACE BOUNDARY/FRONT WILL CONTINUE TO SAG SOUTHWARD LATE ON
FRIDAY INTO SATURDAY AS MID-LEVEL ENERGY PUSHES THROUGH. A COUPLE
OF SURFACE WAVES FORM ALONG THE FRONT AND MOVE TOWARDS THE EAST ON
SATURDAY AS THE FRONT SLOWLY PROGRESSES THROUGH THE REGION. THIS
WILL CONTINUE TO KEEP UNSETTLED WEATHER THROUGHOUT OUR CWA ON
SATURDAY AND PROVIDES ANOTHER DAY OF CONVECTIVE POTENTIAL. AS OF
NOW SATURDAY LOOKS LIKE A BETTER DAY FOR MORE WIDESPREAD
CONVECTIVE ACTIVITY, WHEN COMPARED TO FRIDAY, AS THESE MULTIPLE
WAVES ALOFT PULL THROUGH AND THE MID-LEVEL TROUGHING SLIDES
OVERHEAD.

THE TROUGHING ALOFT DEEPENS AS IT MOVES TOWARDS THE EAST ON
SATURDAY AND SURFACE HIGH PRESSURE SETTLES IN FROM SUNDAY THROUGH
AT LEAST TUESDAY. THE NOW EAST COAST TROUGH WILL REMAIN FAIRLY
STATIONARY THROUGH MID-WEEK, BUT FAR ENOUGH TO OUR EAST TO PUT AN
END OF THE UNSETTLED WEATHER. AS FOR TEMPERATURES, ONCE WE GET
THROUGH THE NEXT COUPLE OF DAYS A RETURN TO NEAR NORMAL IS
EXPECTED THROUGH WEDNESDAY.

.AVIATION /13Z THURSDAY THROUGH MONDAY/...
THE FOLLOWING DISCUSSION IS FOR KPHL, KPNE, KTTN, KABE, KRDG, KILG,
KMIV, KACY AND SURROUNDING AREAS.

POSSIBLE WITH DETAILS TO BE DETERMINED.

OTRW...GRADIENT SW WIND G20-25 KT 16Z- 22Z. PROB30 EVERYWHERE IN
OUR 06Z TAFS...GIVES BEST TIMING WE THINK FOR PRIMARY HEAVY
CONVECTION. THIS ENVIRONMENT SHOULD EASILY PRODUCE STG GUSTY
OUTFLOWS. 00Z/26 SPC WRF REVIEWED FOR THIS TAF ISSUANCE.

TONIGHT...SHOWERS AND SCT STRONG THUNDERSTORMS MOVE E OFF THE
NJ/DE COASTS BY 05Z OR 06Z. MAINLY VFR CONDITIONS EXPECTED WITH W
OCNL CIGS AOA 6000 FT. SW WIND 8 TO 18 KTS IN THE EVENING BECOME
MORE WSW LATE AND DIMINISHING.

OUTLOOK...

FRIDAY THROUGH SATURDAY NIGHT...SCATTERED SHOWERS AND
THUNDERSTORMS POSSIBLE DURING THE AFTERNOON/EVENING HOURS BOTH
DAYS. MAINLY VFR CONDITIONS IN STORE EXCEPT WITHIN HEAVIER
SHOWERS/THUNDERSTORMS. WINDS TURN MORE TOWARDS THE WEST ON FRIDAY
AND SATURDAY.

SUNDAY THROUGH MONDAY...MAINLY VFR CONDITIONS EXPECTED WITH LIGHT
NORTHERLY WINDS TURNING TOWARDS THE EAST BY MONDAY.

&&

.MARINE...
SCA ISSUED FOR DE BAY AND ATLC COASTS. MAY STILL BE TOO SLOW ALONG
THE ATLC COAST.

ISO G 25 KT THIS MORNING. HAD TO COVER FOR DE 431 BRANDYWINE WITH
AN UPDATED ISSUANCE.

SOUTHWEST WIND 15-20 KT THROUGH MIDDAY WITH WIDESPREAD G25 KT
THIS AFTN. WAVE HEIGHTS ON OUR OCEAN WATERS SHOULD BUILD TO 5
FEET LATE IN THE DAY.

SMALL CRAFT CONDITIONS CONTINUE TONIGHT. WINDS START TO DECREASE
AND SHOULD DROP BELOW 25 KNOTS BY LATE TONIGHT WITH SEAS TAKING A
BIT LONGER TO DROP BELOW 5 FEET, NOT UNTIL EARLY FRIDAY MORNING.

OUTLOOK...
FRIDAY AND BEYOND...

SOUTHWESTERLY WINDS TURN MORE TOWARDS THE WEST BY SATURDAY AS A
SURFACE COLD FRONT SLIDES TO OUR SOUTH. A COUPLE OF SURFACE WAVES
FORM ALONG THIS FRONT AND SLIDE TOWARDS THE EAST ON SATURDAY
SPILLING INTO SUNDAY. WIND SPEEDS IN GENERAL WILL BE LIGHT AND
AROUND 10 KNOTS OR LESS. A MORE EAST SOUTHEAST PUSH DEVELOPS
MONDAY AS HIGH PRESSURE SLIDES ACROSS THE REGION. ONCE SEAS DROP
BELOW 5 FEET EARLY FRIDAY MORNING, THEY SHOULD REMAIN BELOW SMALL
CRAFT THROUGH THE REST OF THE FORECAST PERIOD.

A CHANCE FOR SHOWERS AND THUNDERSTORMS EXISTS THROUGH MUCH OF THE
FORECAST PERIOD.
