Special Weather Statement, NWS Philadelphia/Mount Holly

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MOUNT HOLLY NJ
942 PM EDT TUE JUL 20 2010

.SYNOPSIS...
A WEAK WARM FRONT WILL SLOWLY LIFT NORTHWARD TONIGHT. A WEAK COLD
FRONT WILL THEN APPROACH THE REGION FROM THE WEST DURING WEDNESDAY.
HIGH PRESSURE BUILDING IN BEHIND THE FRONT WILL BRING DRIER
CONDITIONS WEDNESDAY NIGHT AND THURSDAY, ALTHOUGH THURSDAY WILL BE
HOT. A WARM FRONT CROSSING THE REGION FRIDAY WILL BRING HOT AND
HUMID WEATHER TO THE REGION FOR THE WEEKEND. THE NEXT COLD FRONT
IS SCHEDULED TO MOVE THROUGH SUNDAY.

&&

.NEAR TERM /UNTIL 6 AM WEDNESDAY MORNING/...
THE FORECAST PROBLEM TONIGHT WILL BE THE EXTENT AND COVERAGE OF
CONVECTION. THIS IS A LOWER CONFIDENCE FORECAST, GIVEN THE MORE
SUBTLE FEATURES.

A SUBTLE SHORT WAVE IS EVIDENT IN A MESOANALYSIS ACROSS SOUTH-
CENTRAL PENNSYLVANIA EARLY THIS EVENING. THIS IS WHAT IS PROBABLY
HELPING TO INITIATE RENEWED CONVECTION TOWARD SOUTHEASTERN
PENNSYLVANIA TO NORTHEASTERN MARYLAND /AS OF 2345Z/. SOME OF THE
STORMS EARLIER HAD SOME ROTATION EVIDENT ALOFT AS THE BETTER
SHEAR IS LOCATED NEAR THE PENNSYLVANIA-MARYLAND BORDER. THE STORMS
TODAY HAD MORE OF AN ELEVATED WIND MAXIMUM THAT TRIED TO LOWER
TOWARD THE SURFACE, AND ALSO SOME CELLS WERE RIGHT-TURNERS. THERE IS
QUITE A MODEL DIFFERENCE HOWEVER ON HOW THE QUASI-STATIONARY FRONT
ACROSS THE SOUTHERN ZONES IS HANDLED. IN THE ENVIRONMENT THAT WE
ARE IN, IT WILL NOT TAKE A LOT OF ADDED LIFT TO GET SOME
CONVECTION GOING AS SOME INSTABILITY IS FORECAST TO LINGER THROUGH
THE NIGHT ALONG WITH SOME SHEAR. AS OF NOW, WE BELIEVE THAT THE
CONVECTION WILL BE ISOLATED TO SCATTERED AS NO REAL STRONG AND
FOCUSED LIFT IS EVIDENT THROUGH THE NIGHT. WE DID HOWEVER SLOW A
BIT THE INCREASE IN POPS FROM WEST TO EAST, WITH THE HIGHEST POPS
GENERALLY ACROSS THE WESTERN ZONES. LOCALLY GUSTY WINDS WILL BE
THE MAIN THREAT FOR AWHILE, BUT GIVEN THE LOWER CHC OF THIS
OCCURRING ACROSS A MORE WIDESPREAD AREA, WE REMOVED ANY ENHANCED
WORDING.

WITH PRECIPITABLE WATER VALUES STILL NEAR 2 INCHES, THERE COULD
BE SOME HEAVY DOWNPOURS. AS LONG AS THE WARM FRONT LIFTS NORTH,
TRAINING OF CELLS SHOULD NOT BE A PROBLEM. THE STORM MOTION SHOULD
BE SUFFICIENT TO KEEP THE FLOOD THREAT TO A MINIMUM. MAY HAVE TO
WATCH FOR TRAINING ALONG THE WARM FRONT LATER TONIGHT, BUT FOR NOW
FLOODING IS NOT EXPECTED TO BE A PROBLEM.

CLOUDS AND THE PASSING WARM FRONT SHOULD KEEP TEMPERATURES FROM
FALLING OFF MUCH. GENERALLY USED A MODEL BLEND FOR LOWS. WE
ADJUSTED THE HOURLY TEMPERATURES GIVEN SOME AREAS REBOUNDED LATE
THIS AFTERNOON AND EARLY EVENING DUE TO INCREASED SUNSHINE. THE
LAMP/LAV GUIDANCE SEEMED TO CATCH THIS TO SOME EXTENT, THEREFORE
WE BLENDED THIS INTO THE DATABASE.

&&

.SHORT TERM /6 AM WEDNESDAY MORNING THROUGH FRIDAY/...
THE WARM FRONT SHOULD PASS WEDNESDAY MORNING. AFTER THIS...THE
CONVECTIVE THREAT IS NOT CLEAR CUT (AT LEAST TO ME). IT COULD BE
THAT MOST OF THE LOW LEVEL MOISTURE CONVERGENCE OCCURS WITH THE WARM
FRONT TONIGHT...WITH DEW POINTS A BIT LOWER FOR WEDNESDAY. THE LOW
LEVEL MOISTURE WILL BE THE KEY AS TO HOW MUCH CONVECTION WILL
DEVELOP AHEAD OF A WEAK MID SHORT WAVE AND SURFACE COLD FRONT.

RIGHT NOW...THE MULTI MODEL CONSENSUS IS FOR CONVECTION TO DEVELOP
IN THE MID AFTERNOON AHEAD OF THE SHORT WAVE. THE BEST INSTABILITY
SHOULD STRETCH FROM NORTHEAST PENNSYLVANIA THROUGH CENTRAL NEW
JERSEY. THE BEST BULK SHEAR WITH THE SHORT WAVE SHOULD BE ACROSS THE
NORTHERN ZONES. THE COMBINATION OF THE TWO...WITH A LEE SIDE TROF
AND EVENTUALLY COOL FRONT TO FOCUS ON...SHOULD RESULT IN THE
POTENTIAL FOR MULTI CELLULAR DEVELOPMENT WITH LINE SEGMENTS AND BOWS
AS THE LIKELY CONVECTIVE MODE.

IN ADDITION..IF THE HEATING IS SUFFICIENT...THE SHEAR COULD BE
STRONG ENOUGH FOR A SUPERCELL OR TWO. WILL INDICATE THE BEST CHANCE
OF SHOWERS AND THUNDERSTORMS ACROSS THE NORTHERN AREAS WEDNESDAY
AFTERNOON.

THE LOW AND MID LEVEL CLOUDINESS ASSOCIATED WITH THE WARM FRONT
SHOULD LIFT DURING THE MORNING HOURS. RAPID HEATING SHOULD OCCUR IN
THE AFTERNOON WITH SUNSHINE IN THE WARM AIRMASS. FOR THE MOST PART...
USED THE GFS MOS NUMBERS FOR HOURLY TEMPERATURES AS WELL AS HIGH
TEMPERATURES. WHILE IT MAY BE CLOSE TO HEAT ADVISORY CRITERIA FOR A
TIME WEDNESDAY AFTERNOON ACROSS CENTRAL NEW JERSEY...NOT ENOUGH
CONFIDENCE TO RAISE THE ADVISORY AT THIS TIME.

THE CONVECTION COULD PERSIST INTO WEDNESDAY EVENING...ESPECIALLY IF
MULTI CELLULAR OR SUPERCELLS DEVELOP. AFTER THIS...THE FRONT SHOULD
CROSS THE REGION...AND DRY OUT THE LOWER LEVELS. IN THE WAKE OF THE
SHORT WAVE...DOWNWARD VERTICAL MOTION SHOULD PROMOTE CLEARING AFTER
MIDNIGHT. WHILE THE COOL FRONT DOES PASS...THE TRUE AIRMASS CHANGE
DOES NOT OCCUR UNTIL THURSDAY. THUS...A BLEND OF MOS NUMBERS WAS
USED FOR LOWS.

THURSDAY LOOKS DRY AS MID LEVEL RIDGING BUILDS OVER THE TOP OF THE
WEAK SURFACE HIGH. DEW POINTS WILL BE LOWER THAN PREVIOUS DAYS...AND
MODEL SOUNDINGS SHOW CAPPING IN PLACE. IN FACT...CONVECTIVE
TEMPERATURES MAY BE JUST OUT OF REACH...SO WILL KEEP SKIES MOSTLY
SUNNY. WHILE THE AIRMASS WILL BE DRIER THURSDAY...850 MB
TEMPERATURES SUGGEST THAT A BLEND OF MOS NUMBERS SHOULD BE OK FOR
HIGHS.

THE SURFACE COOL FRONT THAT PASSES WEDNESDAY EVENING WILL RETURN
FRIDAY AS A WARM FRONT. WHILE THERE MAY BE SOME CONVECTION WITH THE
FRONT IN THE AFTERNOON (ESPECIALLY ACROSS THE NORTH)...THE MAIN
SENSIBLE WEATHER CHANGE WILL BE THE HEAT AND HUMIDITY. DOES NOT
APPEAR AS THOUGH HEAT INDEX VALUES WILL REACH 100 FRIDAY
AFTERNOON...SO NO HEAT HEADLINES AT THIS TIME.

&&

.LONG TERM /FRIDAY NIGHT THROUGH TUESDAY/...
DURING THE PERIOD FROM FRIDAY NIGHT THROUGH TUESDAY, THE UPPER
PATTERN IS EXPECTED TO FEATURE A RIDGE BUILDING OVER THE WESTERN
STATES AND A TROUGH AFFECTING THE GREAT LAKES AND THE NORTHEASTERN
STATES.

AT THE SURFACE, WE ARE ANTICIPATING A COLD FRONT MOVING THROUGH OUR
REGION ON SUNDAY.

AHEAD OF THE COLD FRONT, TEMPERATURES ARE EXPECTED TO BE VERY WARM
WITH OVERNIGHT LOWS MAINLY IN THE 70S. DAYTIME HIGH TEMPERATURES ARE
FORECAST TO BE IN THE UPPER 90S IN OUR CENTRAL AND SOUTHERN COUNTIES
ON SATURDAY. WE MAY NEED AN EXCESSIVE HEAT ADVISORY OR WARNING FOR
OUR URBANIZED AREAS AT THAT TIME. AS THE FRONT PASSES AND AFTER IT
PUSHES TO OUR SOUTH, WE SHOULD HAVE TYPICAL JULY TEMPERATURES FOR
SUNDAY, MONDAY AND TUESDAY. THE HUMIDITY IS EXPECTED TO DROP FOR
MONDAY AND TUESDAY AS HIGH PRESSURE BUILDS INTO OUR REGION FROM THE
WEST.

WE WILL CONTINUE TO MENTION CHANCE POPS OVER THE WEEKEND. THE
SHOWERS AND THUNDERSTORMS SHOULD FAVOR THE AFTERNOON AND EVENING
HOURS ON SATURDAY. THE PRECIPITATION TIMING FOR SUNDAY WILL LIKELY
BE DEPENDENT UPON THE PROGRESS OF THE COLD FRONT.

&&

.AVIATION /02Z WEDNESDAY THROUGH SUNDAY/...
THE FOLLOWING DISCUSSION IS FOR KPHL, KPNE, KTTN, KABE, KRDG, KILG,
KMIV, KACY AND SURROUNDING AREAS.

IT APPEARS AS THOUGH SHOWERS AND THUNDERSTORMS WILL AFFECT KMIV AND
KACY BETWEEN 0200Z AND 0400Z AND THEY HAVE BEEN INSERTED INTO THE
TAFS. OUR REMAINING SIX TAF SITES SHOULD REMAIN VFR, EVEN AS A
SHOWER MAY BRUSH PAST KPHL BETWEEN 0200Z AND 0300Z.

WE ARE INDICATING VFR CONDITIONS THROUGH THE REMAINDER OF THE TAF
PERIOD, WITH THE EXCEPTION OF A TEMPO GROUP FOR MVFR VISIBILITY
VALUES AT KRDG BETWEEN 0800Z AND 1100Z AND PREVAILING MVFR
VISIBILITY VALUES AT KMIV OVERNIGHT.

SOME AFTERNOON AND EARLY EVENING SHOWERS AND THUNDERSTORMS ARE
ANTICIPATED FOR WEDNESDAY. THEY WILL BE ADDED TO LATER TAF ISSUANCES
AS THEIR TIMING AND AREAL COVERAGE BECOMES A LITTLE MORE CERTAIN.

OUTLOOK...
THURSDAY LOOKS AS THOUGH IT WILL BE RAIN FREE. HOWEVER, THERE IS A
CHANCE OF SHOWERS AND THUNDERSTORMS ON FRIDAY, SATURDAY AND SUNDAY.
WITH HIGH HUMIDITY LEVELS, LATE NIGHT AND EARLY MORNING VISIBILITY
RESTRICTIONS ARE POSSIBLE EACH DAY.

&&

.MARINE...
WEAK PRESSURE SYSTEMS WILL CONTINUE TO MIGRATE ACROSS THE REGION
THIS WEEK AS A FRONTAL ZONE OSCILLATES OVER OR NEAR OUR AREA. THE
CLOSE PROXIMITY OF THE FRONT WILL NOT ALLOW THE PRESSURE GRADIENT TO
TIGHTEN. THIS, IN TURN, WILL KEEP WINDS RELATIVELY LIGHT AND
CONDITIONS BELOW SMALL CRAFT ADVISORY CRITERIA. SEAS ON OUR OCEAN
WATERS COULD APPROACH 5 FEET FOR SHORT PERIODS OF TIME, ESPECIALLY
FRIDAY NIGHT AND AGAIN LATE SATURDAY INTO SUNDAY. FOR NOW...SEAS
HAVE BEEN LIMITED TO 4 FEET.

WITH THE FRONTAL ZONE REMAINING CLOSE TO OUR AREA, SHOWERS AND
THUNDERSTORMS COULD OCCUR FROM TIME TO TIME. IT NOW APPEARS THAT
THE THURSDAY/THURSDAY NIGHT TIME FRAME COULD BE DRY. FOR THE
REMAINDER OF THE FORECAST PERIOD, EVEN THOUGH THERE WILL BE A
CHANCE FOR SHOWERS/TSTMS, MOST OF THE TIME CONDITIONS WILL BE
RAIN-FREE ON OUR WATERS. A STRONGER COLD FRONT IS FORECAST TO
CROSS THE AREA BY THE END OF THE WEEKEND. FOLLOWING THIS FRONT
WILL BE A FRESH BATCH OF SLIGHTLY COOLER AND DRIER AIR.
