Special Weather Statement, NWS Philadelphia/Mount Holly

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MOUNT HOLLY NJ
631 AM EDT TUE AUG 14 2012

.SYNOPSIS...
WEAK HIGH PRESSURE OVER THE AREA EARLY THIS MORNING WILL MOVE
OFFSHORE. A COLD FRONT WILL APPROACH THE AREA LATE THIS AFTERNOON
AND TONIGHT. LOW PRESSURE IS EXPECTED TO FORM ON THE FRONT LATE
TONIGHT AND WEDNESDAY MORNING. THE FRONT WILL MOVE OFFSHORE
WEDNESDAY EVENING. HIGH PRESSURE BUILDS IN BEHIND THE FRONT FOR
THURSDAY AND THURSDAY NIGHT. ANOTHER COLD FRONT WILL SLOWLY CROSS
THE AREA FRIDAY INTO SATURDAY

&&

.NEAR TERM /UNTIL 6 PM THIS EVENING/...
THE HIGH PRESSURE SLIDES TO OUR EAST THIS MORNING EVENTUALLY GETTING
ABSORBED INTO THE LARGER HIGH ACROSS THE ATLANTIC. LOW PRESSURE WILL
CROSS THE OHIO VALLEY TODAY AND MAKE ITS WAY INTO WESTERN
PENNSYLVANIA THIS AFTERNOON. A MID LEVEL IMPULSE WILL MOVE INTO THE
AREA THIS MORNING, EXITING TO THE NORTHEAST LATER THIS AFTERNOON.

CLOUDS CONTINUE TO STREAM IN FROM THE SOUTHWEST AS A MID LEVEL
IMPULSE ARRIVES. THERE ARE SOME SHOWERS AND EMBEDDED THUNDERSTORMS
ASSOCIATED WITH THIS IMPULSE WITH THE MAJORITY OF THE STORMS JUST
TO OUR WEST BUT STARTING TO MAKE A SLIGHT EASTWARD PUSH INTO OUR
WESTERN ZONES. WE CONTINUE THE MENTION OF ISOLATED TO SCATTERED
SHOWERS AND THUNDERSTORMS ACROSS THE WESTERN AREAS, EXPANDING
EASTWARD AND INCREASING POPS THROUGH THIS MORNING INTO THIS
AFTERNOON.

THE BEST TIMING FOR CONVECTION LOOKS TO BE THIS AFTERNOON AND
EVENING AFTER WE GET SOME SURFACE HEATING. WITH THE CLOUDS
BUILDING UP THROUGH THE DAY, THIS MIGHT LIMIT OUR SURFACE HEATING
WHICH IN TURN WOULD LIMIT OUR CONVECTIVE POTENTIAL A BIT AND
ESSENTIALLY PUSH BACK THE TIMING ON WHEN THINGS WOULD START TO GET
GOING. SPC STILL CONTINUES TO HIGHLIGHT OUR REGION IN AN AREA OF
SLIGHT RISK FOR SEVERE STORMS. THE MAIN THREAT IS DAMAGING WINDS.
HOWEVER, MODERATE LOW LEVEL FLOW COMBINED WITH LCL'S ONLY A COUPLE
OF THOUSAND FEET ABOVE THE SURFACE THIS AFTERNOON COULD INCREASE
THE POTENTIAL FOR OVERTURNING OF THE ATMOSPHERE, WHICH WOULD LEAD
TO SOME ROTATION IN STORMS THAT DEVELOP. THIS CURRENTLY LOOKS BEST
ACROSS THE DELMARVA AND WILL NEED TO BE MONITORED TODAY.

TEMPERATURES SHOULD RISE INTO THE LOW TO MID 80S ACROSS THE REGION
BUT AS MENTIONED BEFORE, CLOUD COVER COULD KEEP US COOLER THAN
CURRENTLY FORECAST.

&&

.SHORT TERM /6 PM THIS EVENING THROUGH 6 AM WEDNESDAY/...
SHOWERS AND THUNDERSTORMS WILL CONTINUE INTO THIS EVENING AND
OVERNIGHT IN ADVANCE OF A COLD FRONT. POPS WILL INCREASE FROM WEST
TO EAST AS THE COLD FRONT APPROACHES FROM THE WEST.

TEMPERATURES OVERNIGHT WILL BE MILD AS THERE WILL BE PLENTY OF
CLOUDS AROUND. FOG WILL BE POSSIBLE AS PLENTY OF LOW LEVEL MOISTURE
WILL REMAIN IN THE REGION UNTIL THE FRONT PUSHES THROUGH.

&&

.LONG TERM /WEDNESDAY THROUGH MONDAY/...
CONVECTIVE POTENTIAL WEDNESDAY AND FRIDAY ARE THE FORECAST
HIGHLIGHTS OF THIS PERIOD.

NEAR/SHORT TERM MODELS ARE ALL SHOWING A SURFACE WAVE TRYING TO
DEVELOP ON THE FRONT...AS SHORT WAVE ENERGY SHOOTS EAST AHEAD OF THE
LOW WAVE TROUGH OVER THE WESTERN GREAT LAKES. WHILE THERE ARE SOME
MODEL DIFFERENCE REGARDING TIMING...THE 0000 UTC NAM SOLUTION
APPEARS TO BE THE ODD MAN OUT WITH RESPECT TO HOW THE LOW LEVEL
WINDS EVOLVE. FOR NOW...THE GENERAL MODEL CONSENSUS TIMING WAS USED
FOR THIS FORECAST.

THE WEST SOUTHWEST FLOW IN THE MID LEVELS WILL CONTINUE THE INFLUX
OF MOISTURE AHEAD OF THE SLOWING FRONT. PRECIPITABLE WATER VALUES
TOP OUT NEAR 1.75 INCHES DURING THE LATE MORNING AND EARLY
AFTERNOON..WITH THE HIGHEST VALUES ACROSS EASTERN SECTIONS. THE
POSITION OF THE FRONT SUGGESTS THAT THE BEST CHANCE OF SHOWERS AND
THUNDERSTORMS WOULD BE ACROSS THE EASTERN HALF OF THE AREA...AND THE
FORECAST WILL REFLECT THIS.

THE AIRMASS AHEAD OF THE FRONT HAS THE POTENTIAL TO BECOME
MARGINALLY TO LOCALLY MODERATELY UNSTABLE. MODIFIED MODEL SOUNDINGS
SUGGEST THAT THE MOST UNSTABLE PORTION OF THE AIRMASS (AS MEASURED
BY MLCAPE) SHOULD BE SOUTHEAST OF THE I 95 CORRIDOR. IN THESE
AREAS...THE INSTABILITY AND SHEAR COULD BE ENOUGH FOR
ORGANIZATION...WITH GUSTY WINDS POSSIBLE. IN ADDITION...STEEPENING
MID LEVEL LAPSE RATES SUGGEST THE POTENTIAL FOR HAIL IN STRONGER
CELLS AS WELL.

THE ABOVE IS PROBABLY ENOUGH FOR A MENTION OF GUSTY WINDS AND HAIL
IN THE HAZARDOUS WEATHER OUTLOOK FOR WEDNESDAY. MODEL SOUNDINGS
SUGGEST THAT THE POTENTIAL WANES DURING THE AFTERNOON...AS THE FRONT
PASSES AND THE LOWER LEVELS STABILIZE.

FURTHER NORTH AND WEST...THE LOW LEVEL INSTABILITY IS NOT AS
PLENTIFUL...SUGGESTING THAT STRONG SURFACE BASED CONVECTION IS NOT
AS LIKELY. CLOUDINESS COULD END UP BEING A CONSIDERATION AS WELL...
AS THE MID LEVEL SOUTHWEST FLOW DOES NOT SUGGEST QUICK CLEARING
BEHIND THE FRONT. THE GFS MOS NUMBERS LOOK A TAD TOO HIGH FOR
WEDNESDAY...MAINLY BECAUSE OF THE CLOUDINESS.

CONVECTION SHOULD SLOWLY DIE OFF WEDNESDAY EVENING...ESPECIALLY
ACROSS THE NEW JERSEY SHORE AND DELAWARE...WHERE INSTABILITY COULD
REMAIN INTO THE EARLY MORNING HOURS OF THURSDAY. A FINAL MID LEVEL
SHORT WAVE PASSING JUST NORTH OF THE AREA LATE WEDNESDAY NIGHT
SHOULD FINALLY GIVE THE COLD FRONT A KICK FURTHER OFFSHORE.

CLEARING SHOULD OCCUR AFTER THE SHORT WAVE PASSAGE. SINCE THE LOW
LEVEL AIRMASS TRANSITION DOES NOT OCCUR UNTIL LATE (OR EVEN THURSDAY
MORNING)...LOWS WERE GENERALLY BASED ON THE SLIGHTLY WARMER GFS MOS
NUMBERS.

THURSDAY LOOKS LIKE THE BEST DAY OF THE LONG TERM...WITH A QUASI
ZONAL FLOW IN THE MID LEVELS AND WEAK HIGH PRESSURE AT THE SURFACE.
DECENT MID LEVEL LAPSE RATES COULD RESULT IN CUMULUS DEVELOPMENT
THURSDAY...ESPECIALLY ACROSS THE HIGHER TERRAIN. HOWEVER...THE
COLUMN LOOKS TOO DRY FOR ANYTHING MORE THAN THAT. THE PRESSURE
GRADIENT FLOW MAY BE ENOUGH TO KEEP SEA AND BAY BREEZES IN CHECK.
THIS MEANS HIGHS MAY BE MORE UNIFORM ACROSS THE REGION THURSDAY THAN
MOST DAYS THIS TIME OF YEAR. HIGHS WERE BASED ON THE MOS BLEND...AS
THE SLIGHTLY COOLER NAM MOS NUMBERS IN MOST PLACES.

AFTER RIDGING IN THE LOWER TO MID LEVELS MOVES OFFSHORE THURSDAY
NIGHT...THE RETURN FLOW MEANS THAT THE LOW AND MID LEVEL MOISTURE
START TO RETURN FRIDAY. THE MID LEVEL FLOW BACKS TO THE SOUTHWEST
AHEAD OF A FAIRLY DEEP 500 MB TROUGH FOR MID AUGUST (HEIGHTS NEAR
THE TROUGH AXIS ALMOST 3 STANDARD DEVIATIONS BELOW NORMAL). THIS
MEANS THAT THE COLUMN WARMS OVERALL...AND THIS IS REFLECTED IN THE
LOW LEVEL TEMPERATURE ADVECTION. FRIDAY LOOKS LIKE THE WARMEST DAY
OF THE WEEK...AS 850 MB TEMPERATURES SUPPORT HIGHS NEAR 90 IN THE
PHILADELPHIA METRO AREA.

FRIDAY ALSO LOOKS CONVECTIVELY ACTIVE. MARGINAL INSTABILITY SHOULD
BE PRESENT IN THE AFTERNOON AND EVENING...ALONG WITH INCREASING BULK
SHEAR AHEAD OF THE APPROACHING LONG WAVE TROUGH. THE FRONTAL TIMING
APPEARS TO BE FRIDAY NIGHT...SO THE LEE SIDE TROUGH WOULD BE NEEDED
FOR SURFACE CONVERGENCE. OTHERWISE...SURFACE CONVERGENCE WOULD BE
THE LIMITING FACTOR FOR A MORE ORGANIZED CONVECTION SCENARIO.

THE DETAILS OF THE WEEKEND ARE NOT IN ANY BETTER FOCUS EARLY THIS
MORNING. THE POSITION OF THE LONG WAVE TROUGH...AND THE SHORT WAVES
SHOOTING THROUGH IT...SUGGEST THAT TIMING/POSITION OF SYNOPTIC SCALE
FEATURES WILL BE PROBLEMATIC. BECAUSE OF THIS...NOT MUCH IN THE
CURRENT FORECAST WAS CHANGED AFTER SATURDAY NIGHT.

&&

.AVIATION /12Z TUESDAY THROUGH SATURDAY/...
THE FOLLOWING DISCUSSION IS FOR KPHL, KPNE, KTTN, KABE, KRDG, KILG,
KMIV, KACY AND SURROUNDING AREAS.

VFR CONDITIONS ARE EXPECTED TO START THE DAY. CEILINGS WILL START TO
LOWER AS A MID LEVEL IMPULSE MOVES INTO THE AREA, BRINGING SOME
SHOWERS AND ISOLATED THUNDERSTORMS LATER THIS MORNING. SHOWERS
LOOK TO IMPACT KRDG AND KABE BETWEEN 11-15Z, KILG KPNE AND KPHL
BETWEEN 12-15Z AND KTTN BETWEEN 14-16Z. CHANCES ARE LESS FOR
STORMS TO IMPACT KMIV AND KACY THIS MORNING AND WE HAVE LEFT IT
OUT OF THE TAF AT THIS TIME.

CONVECTION WILL BE POSSIBLE AGAIN THIS AFTERNOON AND EVENING, IN
ADVANCE OF A SURFACE COLD FRONT. WITH TIMING AN ISSUE, WE HAVE
INCLUDED A PROB30/TEMPO GROUPS TO COVER THE TIME WE FEEL STORMS
WILL HAVE THE BIGGEST IMPACT AT THE TERMINALS. OTHERWISE,
CEILINGS WILL GENERALLY BE SCATTERED TO BROKEN AT AROUND
4000-6000FT THROUGH TODAY. CEILINGS AND VISIBILITIES MAY DROP DOWN
TO MVFR AT TIMES, ESPECIALLY IN CONVECTION, AND THEN AGAIN
OVERNIGHT BEFORE STARTING TO IMPROVE TOWARD WEDNESDAY.

WINDS WILL REMAIN LIGHT INTO THIS MORNING, PICKING UP A BIT THIS
AFTERNOON OUT OF THE SOUTH SOUTHWEST. WINDS SPEEDS WILL BE AROUND 10
KNOTS OR LESS.

OUTLOOK...
WEDNESDAY...DEPENDING ON HOW WIDESPREAD SHOWERS ARE EARLY...MVFR/IFR
CONDITIONS ARE POSSIBLE SOUTH AND EAST OF KPHL IN THE MORNING.
MAINLY VFR IN THE AFTERNOON WITH SCATTERED SHOWERS AND THUNDERSTORMS.

WEDNESDAY NIGHT...LOCAL MVFR CONDITIONS POSSIBLE IN SHOWERS EARLY
SOUTHEAST OF KPHL...OTHERWISE VFR.

THURSDAY...VFR CONDITIONS ARE EXPECTED.

FRIDAY...PATCHY MVFR FOG IS POSSIBLE EARLY. MAINLY VFR WITH SCATTERED
SHOWERS AND THUNDERSTORMS IN THE AFTERNOON AND EVENING.

SATURDAY...DEPENDING ON THE POSITION OF A FRONT...MAINLY VFR
CONDITIONS ARE EXPECTED. CONFIDENCE IN THIS IS LOW.

&&

.MARINE...
CONDITIONS ON THE AREA WATERS WILL REMAIN BELOW SMALL CRAFT CRITERIA
TODAY. SEAS WILL BE AROUND 2 FEET ON THE OCEAN AND 1 TO 2 FEET IN
THE DELAWARE BAY. WINDS WILL MAINLY BE OUT OF A SOUTHERLY DIRECTION,
BECOMING MORE SOUTHEASTERLY THIS AFTERNOON AND EVENING. SPEEDS WILL
GENERALLY BE AROUND 10 TO 15 KNOTS. WITH A SOUTHEAST WIND DEVELOPING
THROUGH THE DAY, THE CHANCE FOR GUSTIER WINDS ON THE DELAWARE BAY
WILL EXIST DUE TO FUNNELING UP THE BAY. WIND GUSTS UP AROUND 20
KNOTS ARE POSSIBLE FROM THIS AFTERNOON THOUGH THIS EVENING.

OUTLOOK...
LOW PRESSURE FORMING ON THE COLD FRONT WILL SLOW ITS PROGRESS
WEDNESDAY INTO WEDNESDAY EVENING. AT THIS POINT...THE PRESSURE
GRADIENT DOES NOT LOOK TO SUPPORT WINDS ABOVE 20 KNOTS. IN FACT...
THE GRADIENT COULD EVEN BE WEAK ENOUGH TO SUPPORT LOCAL SEA AND BAY
BREEZES DEVELOP IN THE LATE MORNING AND EARLY AFTERNOON.

ONCE THE FRONT DOES MOVE OFFSHORE...THE LOW LEVEL PUSH OF COOLER AIR
MAY BE ENOUGH TO ALLOW WEST TO NORTHWEST WINDS TO GUST TO 20 KNOTS
FOR A TIME LATE WEDNESDAY NIGHT AND THURSDAY MORNING. MODEL
SOUNDINGS SUGGEST THAT 20 KNOTS SHOULD BE THE TOP END OF THE GUSTS
THROUGH THURSDAY MORNING.

AS HIGH PRESSURE BUILDS OFFSHORE THURSDAY NIGHT...THE RETURN FLOW
INCREASING...AND WINDS COULD START GUSTING TO NEAR 20 KNOTS BY
FRIDAY MORNING. THE GRADIENT FLOW AHEAD OF A SLOW MOVING COLD FRONT
MAY BE ENOUGH TO SUPPORT WIND GUSTS NEAR 20 KNOTS. HOWEVER...MODEL
SOUNDINGS SUGGEST THAT THE THE DEPTH OF THE MIXED LAYER WILL CUT OFF
ACCESS TO HIGHER WINDS ABOVE THE INVERSION.

THE SOUTH TO SOUTHWEST FETCH AHEAD OF THE FRONT MAY BE IN PLACE LONG
ENOUGH FOR SEAS TO GET CLOSE TO 5 FEET ON THE OCEAN FRIDAY NIGHT AND
SATURDAY MORNING. HOWEVER...CONFIDENCE IN THIS IS LOW SINCE IT IS
UNCLEAR JUST HOW MUCH MOMENTUM WILL MAKE IT TO THE SEA SURFACE IN
THE SOUTH TO SOUTHWEST FLOW.
