TUESDAY. THIS REPLACED THE PREVIOUSLY ISSUED EXCESSIVE WATCH FOR
MONDAY AND TUESDAY. IN ADDITION...AN EXCESSIVE HEAT WATCH HAS ALSO
BEEN ISSUED FROM TUESDAY EVENING THROUGH WEDNESDAY EVENING.

* HEAT INDEX VALUES...AROUND 100 DEGREES EACH AFTERNOON MONDAY
  THROUGH WEDNESDAY DUE TO FORECAST HIGH TEMPERATURES IN THE MID

  THE HEAT OVERNIGHT WITH LOW TEMPERATURES ONLY IN THE 70S.

* TIMING...THE HIGHEST HEAT INDICES SHOULD OCCUR BETWEEN 2 PM AND

  CARS DURING THE DAY IS DANGEROUS AND QUICKLY CAN BECOME FATAL!

* OUTLOOK...THIS HEAT WAVE IS EXPECTED TO CONTINUE UNABATED THROUGH
  FRIDAY OR POSSIBLY SATURDAY. HEAT INDICES MAY BE SLIGHTLY HOTTER
  THURSDAY AND FRIDAY. THIS PERSISTENTLY HOT WEATHER THROUGH THE
  ENTIRE WEEK CAN SHORTEN TEMPERS. KEEP COOL AS MUCH AS POSSIBLE
  AND DRINK PLENTY OF NON ALCOHOLIC COOLING BEVERAGES.


PRECAUTIONARY/PREPAREDNESS ACTIONS...

AN EXCESSIVE HEAT WARNING MEANS THAT A PROLONGED PERIOD OF
DANGEROUSLY HOT TEMPERATURES WILL OCCUR. THE COMBINATION OF HOT
TEMPERATURES AND HIGH HUMIDITY WILL CREATE A DANGEROUS SITUATION

RELATIVES AND NEIGHBORS.

TAKE EXTRA PRECAUTIONS IF YOU WORK OR SPEND TIME OUTSIDE. WHEN

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MOUNT HOLLY NJ
1242 PM EDT SAT JUL 13 2013

.SYNOPSIS...
A FRONTAL BOUNDARY WILL REMAIN NEARBY THROUGH TODAY AND THEN
GRADUALLY WEAKEN BY SUNDAY AS IT SLOWLY DRIFTS WESTWARD. MEANWHILE,
BERMUDA HIGH PRESSURE ACROSS THE WESTERN ATLANTIC BUILDS BACK INTO
OUR REGION BY THE END OF THE WEEKEND, BRINGING A RETURN TO
INCREASING HEAT AND HUMIDITY THROUGH THE UPCOMING WORK WEEK.

&&

.NEAR TERM /UNTIL 6 PM THIS EVENING/...
MAX TEMP FCST FOR THIS AFTN LOOKS REASONABLE WITH LOW TO MID 80S
EVERYWHERE EXCEPT HIER TERRAIN OF NW NJ AND POCONONS...AND
POSSIBLY ALONG SOME BEACHES WHERE SURF TEMPS ARE STILL IN THE 60S.
CLOUD BASES HAS LIFTED SOME BUT THERE IS STILL A GOOD BIT OF CLOUD
COVER AND LOW LEVEL MOISTURE AROUND. HAVE LOWERED POPS SMWHT FOR
THIS AFTN WHICH IS MORE IN LINE WITH LATEST MOS GUIDANCE AND
SURROUNDING OFFICES. HWVR WILL STILL MAINTAIN CHC POPS...SLIGHTLY
HIGHER N AND W OF PHL...AS PLENTY OF MOISTURE AND SOME INSTBY
REMAIN OVER THE AREA. THERE DOESN'T SEEM TO BE MUCH LARGE SCALE
LIFT AS THE UPPER LOW HAS SHIFTED WELL TO THE WEST AND WE ARE
COMING MORE UNDER THE INFLUENCE OF AN UPPER-LEVEL ANTI-CYCLONE.
HWVR THE RADAR SHOWS A FEW SMALL SHOWERS OVER NJ AND A MODEST
INCREASE IN CONVECTION IS EXPECTED FOR THE AFTN.

&&

.SHORT TERM /6 PM THIS EVENING THROUGH 6 AM SUNDAY/...
TONIGHT...MUGGY WITH STRATUS AND FOG EXPECTED. CONSIDERABLE SUPPORT
FROM THE SREF PROBS OF IFR-MVFR VSBY AND CIGS. THE FOG COULD BE
DENSE LATE TONIGHT BUT ITS SUMMER AND NIGHTS ARE SHORTER SO CONFIDENCE
ON WHERE IF AND WHEN DENSE IS LESS THAN AVG.

FAVORED THE WARMER OF THE 00Z/13 GFS/NAM GUIDANCE.

&&

.LONG TERM /SUNDAY THROUGH FRIDAY/...
OVERALL, OUR WEATHER THROUGH THE LONG TERM PERIOD WILL BE LARGELY
INFLUENCED BY BERMUDA HIGH PRESSURE, AS IT SETTLES ACROSS MUCH OF
THE EASTERN UNITED STATES. THIS WILL BE SUPPORTED BY MID-LEVEL
RIDGING/MID-LEVEL HIGH, WHICH WILL BE IN PLACE THROUGH MUCH OF THE
UPCOMING WORK WEEK, BEFORE THE FLOW ALOFT GRADUALLY BECOMES MORE
ZONAL BY THE END OF THE WEEK.

ON SUNDAY, A LINGERING FRONTAL BOUNDARY NEAR OUR AREA WILL CONTINUE
TO DISSIPATE AND MIX-OUT AS LARGE BERMUDA HIGH PRESSURE ACROSS THE
WESTERN ATLANTIC BEGINS TO RETROGRADE AND BUILD WESTWARD INTO THE
EASTERN UNITED STATES. MODEL SOUNDINGS SHOW SUFFICIENT SURFACE
INSTABILITY DEVELOPING SUNDAY, AND THIS LINGERING BOUNDARY MAY BE
ENOUGH TO HELP FOCUS SOME CONVECTIVE ACTIVITY. PWATS WILL STILL BE
ELEVATED, RANGING BETWEEN 1.5 TO 2.0 INCHES, AND ANY SHWRS/TSTORMS
THAT DEVELOP WILL BE EFFICIENT RAIN PRODUCERS. WE HAVE KEPT A
MENTION OF SCATTERED TO ISOLATED TSTORMS IN PLACE FOR SUNDAY AND
GENERALLY LOW CHANCE POPS, AS THE INCOMING BERMUDA HIGH WILL ALSO
PROVIDE SOME SUBSIDENCE ACROSS THE REGION.

THROUGH THE UPCOMING WORK WEEK, THIS OVERALL TREND OF DIURNALLY
DRIVEN CONVECTION WILL PERSIST AS DAYTIME HEATING DESTABILIZES THE
ATMOSPHERE, LEADING TO SOME ISOLATED TO SCATTERED TSTORMS EACH
AFTERNOON/EVENING. ALSO OF CONCERN FOR THE END OF THE WEEKEND AND
THROUGH THIS WEEK WILL BE THE INCREASING HEAT AND HUMIDITY EXPECTED
WITH THIS BERMUDA HIGH PATTERN. TEMPERATURES AND DEWPOINTS ARE
EXPECTED TO STEADILY CLIMB DAY BY DAY, WITH MUCH OF THE FORECAST
AREA LOOKING AT MAX TEMPERATURES INTO THE LOWER 90S AND EVEN MIDDLE
90S BY MID-WEEK. IN ADDITION, MODEL DATA ALSO SHOWS STEADILY
CLIMBING DEWPOINTS, REACHING THE LOWER TO PERHAPS MID 70S AT TIMES,
MAKING FOR A VERY MUGGY AIRMASS. AT THIS TIME, WE EXPECT HEAT
INDICES TO REACH THE UPPER 90S AND EVEN LOW 100S THROUGH MOST OF THE
SOUTHERN HALF OF OUR CWA AND INTO URBANIZED AREAS, ESPECIALLY BY
MID-WEEK.

&&

.AVIATION /16Z SATURDAY THROUGH WEDNESDAY/...
THE FOLLOWING DISCUSSION IS FOR KPHL, KPNE, KTTN, KABE, KRDG, KILG,
KMIV, KACY AND SURROUNDING AREAS.

TODAY...CIGS/VSBYS HAVE IMPROVED TO VFR LEVELS OR SOON WILL AT ALL
TAF SITES. SOME SHOWERS AND THUNDERSTORMS ARE POSSIBLE THIS AFTERNOON.
HOWEVER, THE TIMING AND ESPECIALLY THE COVERAGE REMAINS LOW
CONFIDENCE THEREFORE A VCSH WAS ONLY USED. AS EXPECTED WINDS HAVE
BECOME SOUTH TO SOUTHEAST NEAR 10 KNOTS AND SHOULD REMAIN SO FOR
THE AFTERNOON.

TONIGHT...AREAS OF 500 TO 1500 FT STRATUS EXPECTED WITH POSSIBLE
PATCHY IFR FOG IN LEFTOVER MOISTURE AND LIGHT S-SW WIND.

OUTLOOK...
SUNDAY THROUGH WEDNESDAY...MAINLY VFR CONDITIONS. ISOLATED TO
SCATTERED SHWRS/TSTORMS EACH AFTN/EVE COULD PRODUCE LOCAL MVFR OR
LOWER CONDITIONS.

&&

.MARINE...
NO SCA ANTICIPATED THROUGH TONIGHT.

FLOW WILL BE PROCEEDING FROM SE-S-SW WITH TIME DURING THE NEXT
24 HOURS AND UNDER 20 KT. PATCHY FOG MIGHT BE A PROBLEM AT TIMES.

OUTLOOK...
FROM SUNDAY THROUGH THE MID-WEEK PERIOD, SUB-SCA CONDITIONS ARE
EXPECTED FOR OUR COASTAL WATERS AND DELAWARE BAY, AS AN AREA OF HIGH
PRESSURE SETTLES ACROSS THE REGION. EACH AFTERNOON TO EVENING,
ISOLATED TO SCATTERED SHWRS/TSTORMS ARE POSSIBLE, WHICH COULD CAUSE
REDUCED VISIBILITIES AND LOCALLY GUSTY WINDS.

&&

.CLIMATE...
RERGED FOR 7/12/13 FOR RAINFALL.

THROUGH THE 19TH...PHL CURRENT 3.5 DEGREES ABOVE NORMAL THROUGH
THE 12TH...WILL BE SIMILARLY POSITIVELY ABOVE NORMAL THROUGH 19
DAYS....MAYBE EDGING UP TO 4 DEGREES ABOVE NORMAL. SIMILAR
POSITIVE DEPARTURES IN THE REMAINDER OF OUR CWA WILL CONTINUE
THROUGH THE 19TH.
