Special Weather Statement, NWS Philadelphia/Mount Holly

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MOUNT HOLLY NJ
622 PM EDT THU JUL 3 2014

.SYNOPSIS...
HURRICANE ARTHUR WILL PULL AWAY FROM THE MIDDLE ATLANTIC COAST
AND MOVE OFF TO THE NORTHEAST EARLY SATURDAY. MEANWHILE...A COLD
FRONT WILL CROSS THE REGION TONIGHT FOLLOWED BY HIGH PRESSURE FOR
THE WEEKEND. THE HIGH WILL SLIDE ACROSS THE OHIO VALLEY AND THEN
SHIFT TO THE SOUTH AND EAST OF THE AREA, ANCHORING OVER THE
WESTERN ATLANTIC SUNDAY NIGHT INTO MONDAY. A LEE SIDE TROUGH LOOKS
TO DEVELOP ACROSS OUR AREA ON MONDAY AND PERSIST THROUGH THURSDAY.
A LOW PRESSURE SYSTEM WELL TO OUR NORTH WILL SLOWLY PUSH A COLD
FRONT INTO THE REGION WEDNESDAY AND THURSDAY.

&&

.NEAR TERM /UNTIL 6 AM FRIDAY MORNING/...
SEVERE THUNDERSTORM WATCH 391 REMAINS IN EFFECT FOR OUR ENTIRE
FORECAST AREA UNTIL 1000 PM.

THE GFS INITIALIZATION LOOKED BETTER THAN THE WRF-NMMB WITH
ARTHUR. WHILE THE INITIALIZATION LOOKED SLIGHTLY TOO FAR WEST, ITS
RIDGING EAST OF ARTHUR WAS WEAKER THAN REALITY. AT 18Z, THE ECMWF
HAS VERIFIED THE BEST WITH THE SFC POSITION OF ARTHUR. THE MODELS
ARE OVERALL FASTER AND NOT AS WIDE RIGHT. THIS FCST PACKAGE IS
GOING TO FOLLOW THE ECMWF GUIDANCE THE CLOSEST.

A SOLID LINE OF THUNDERSTORMS HAS FORMED OVER THE APPALACHIANS AND
DOWN TO THE CHESAPEAKE BAY REGION AND THERE REMAINS CORROBORATIVE
MESOSCALE MODEL TIMING THAT THIS FEATURE WILL WORK ITS WAY THROUGH
OUR CWA THIS EVENING. THERE IS BETTER FCST BULK SHEAR IN THE
NORTHWESTERN PART OF OUR CWA CLOSER TO THE ENTRANCE REGION OF THE
250MB JET. AS IS OFTEN THE CASE, THE HIGHEST CAPES ARE IN THE SERN
PART OF OUR CWA AND ML CAPES ARE CURRENTLY AROUND 3000J. THIS
UNSTABLE AIR MASS WHILE FINDING SOME CAPPING NOW, SHOULD SUPPLY
AMPLE FUEL FOR THUNDERSTORMS THIS EVENING TOO ONCE UPWIND GUST
FRONTS PROVIDE THE NECESSARY LIFT.

AS FAR AS HEAVY RAIN POTENTIAL GOES, THE FORMATION OF THE PRE IS
STARTING AND THE ENTRANCE REGION OF THE 250MB JET THIS EVENING
FAVORS THE NWRN HALF OF OUR CWA. A SECOND PRE IS THEN PREDICTED TO
SHIFT EASTWARD LATER TONIGHT INTO FRIDAY MORNING OVER OUR EASTERN
CWA. THE FLASH FLOOD WATCH REMAINS IN EFFECT. SEE FURTHER DETAILS
IN THE HYDROLOGY SECTION.

&&

.SHORT TERM /6 AM FRIDAY MORNING THROUGH 6 PM FRIDAY/...
AS ARTHUR PASSES EAST OF OUR CWA, THE EMPHASIS FOR THE HEAVIEST
RAIN ON FRIDAY MORNING WILL BE IN NJ AND DE. THE THUNDER POTENTIAL
WAS TIED TO THE ECMWF'S PREDICTED SHOWALTER INSTABILITY ALOFT.
GRADUAL IMPROVEMENT WILL OCCUR AS FRIDAY MOVES ALONG AND WITH
DRIER AIR MIXING IN ON THE WESTERN SIDE, BETTER MIXING AND A
BREEZY DAY IS EXPECTED. CURRENT WIND GUSTS MAY BE A BIT TOO
CONSERVATIVE. MAX TEMPS ARE BASED ON LATE IN THE DAY SUNSHINE.

&&

.LONG TERM /FRIDAY NIGHT THROUGH THURSDAY/...
AT THE SURFACE...HURRICANE ARTHUR WILL BE PULLING AWAY FROM THE
MIDDLE ATLANTIC COAST AND MOVE OFF TO THE NORTHEAST EARLY
SATURDAY. HIGH PRESSURE WILL SLIDE ACROSS THE OHIO VALLEY AND THEN
SHIFT TO THE SOUTH AND EAST OF THE AREA, ANCHORING OVER THE
WESTERN ATLANTIC SUNDAY NIGHT INTO MONDAY. A LEE SIDE TROUGH LOOKS
TO DEVELOP ACROSS OUR AREA LATE MONDAY INTO TUESDAY AND PERSIST
THROUGH THURSDAY. A LOW PRESSURE SYSTEM WELL TO OUR NORTH WILL
SLOWLY PUSH A COLD FRONT INTO THE REGION WEDNESDAY AND THURSDAY.

IN THE MID LEVELS...SLIGHT TROUGHING WILL BECOME MORE ZONAL OVER
THE WEEKEND AND THEN CONTINUE INTO EARLY NEXT WEEK. SEVERAL
SHORTWAVES WILL ROTATE THROUGH THE ZONAL FLOW THROUGH THE EARLY TO
MID-WEEK PERIOD.

FRIDAY NIGHT...BY FRIDAY NIGHT IT LOOKS LIKE HURRICANE ARTHUR
WILL HAVE MOVED EAST OF THE AREA. WE SHOULD START TO SEE IMPROVING
CONDITIONS AS THE STORM PULLS FURTHER AWAY AND OFF TO THE
NORTHEAST OVERNIGHT. EXPECT WINDS TO REMAIN PRETTY GUSTY THROUGH
THE NIGHT, ESPECIALLY CLOSER TO THE COAST, WITH DECREASING SPEEDS
AS YOU HEAD TOWARD SATURDAY MORNING.

SATURDAY THROUGH SUNDAY...HIGH PRESSURE WILL SLIDE EASTWARD FROM
THE OHIO VALLEY AND WILL INFLUENCE OUR WEATHER THROUGH THE
WEEKEND. THE WEATHER OVERALL SHOULD BE ENJOYABLE WITH DRY
CONDITIONS. SATURDAY WILL BE A BIT GUSTY EARLY UNTIL THE GRADIENT
STARTS TO SLACKEN AND THEN IT SHOULDN'T BE TOO WINDY THROUGH THE
AFTERNOON AND EVENING. OTHERWISE, SUNNY SKIES WITH HIGHS INTO THE
80S ARE EXPECTED.

MONDAY THROUGH THURSDAY...THE HIGH SLIDES TO THE SOUTHEAST OF THE
AREA AND ANCHORS ITSELF IN THE WESTERN ATLANTIC. THE RETURN FLOW
AROUND THE HIGH WILL BEING A RETURN TO A DOMINANT SOUTHWESTERLY
FLOW. THIS MEANS WE WILL START TO FEEL THE HEAT AND HUMIDITY CREEP
UP OVER THE NEXT SEVERAL DAYS. THIS MEANS AFTER A NICE AND
RELATIVELY COOL WEEKEND, TEMPERATURES WILL ONCE AGAIN REACH INTO
THE 90S AND FEEL EVEN WARMER.

A LEE SIDE TROUGH WILL DEVELOP ON MONDAY AND WILL START TO BECOME
A FOCUS FOR CONVECTIVE DEVELOPMENT THROUGH THE FIRST HALF OF THE
WEEK. A COLD FRONT WILL START TO CREEP TOWARDS THE REGION ON
TUESDAY BUT WILL BE VERY SLOW MOVING AND MAY NOT EVEN MAKE IT INTO
OUR WESTERN ZONES UNTIL WEDNESDAY.

&&

.AVIATION /22Z THURSDAY THROUGH TUESDAY/...
THE FOLLOWING DISCUSSION IS FOR KPHL, KPNE, KTTN, KABE, KRDG,
KILG, KMIV, KACY AND SURROUNDING AREAS.

DURING THIS EVENING WE ARE FORECASTING A LINE OF STRONG, ISOLATED
SEVERE, TSTMS TO MOVE THROUGH THE TERMINAL AREA. WE ARE EXPECTING
MVFR CONDITIONS TO PREVAIL, BUT BRIEF IFR CONDITIONS ARE POSSIBLE.
WIND GUSTS ABOVE 30KTS ARE LIKELY, ESPECIALLY WESTERN AIRPORTS.

OVERNIGHT THE CONGEALING OF MOISTURE FROM ARTHUR AND THE FRONTAL
BOUNDARY SHOULD CAUSE WIDESPREAD MVFR CONDITIONS IN SHOWERS.
WIDELY SCATTERED THUNDER WILL OCCUR, BUT TOO LOW COVERAGE TO
INCLUDE. WINDS WILL BE LIGHT.

ON FRIDAY, VERY SLOW IMPROVEMENT FROM WEST TO EAST TO VFR LEVELS.
MIGHT NOT BE TIL THE AFTERNOON AT KMIV AND KACY. NORTH WINDS WILL
INCREASE WITH SUSTAINED SPEEDS AT 10 TO 15 KNOTS AND GUSTS
APPROACHING OR EXCEEDING 20 KTS.

OUTLOOK...
FRIDAY NIGHT THRU SATURDAY...VFR CONDITIONS EXPECTED. GUSTY WINDS
WILL CONTINUE FRIDAY NIGHT INTO SATURDAY AS HURRICANE ARTHUR
PUSHES FURTHER TO OUR EAST. WINDS WILL DIMINISH DURING THE DAY
SATURDAY WITH GUSTIEST WINDS EXPECTED CLOSEST TO THE COAST.

SUNDAY...VFR CONDITIONS EXPECTED.

MONDAY...MAINLY VFR CONDITIONS EXPECTED. CHANCE FOR AFTERNOON
SHOWERS AND THUNDERSTORMS TO THE NORTH AND WEST OF KPHL.

TUESDAY...MAINLY VFR CONDITIONS EXPECTED WITH SHOWERS AND
THUNDERSTORMS POSSIBLE, MAINLY IN THE AFTERNOON AND EVENING.

&&

.MARINE...
WE UPPED THE STARTING TIME OF THE SMALL CRAFT ADVISORY ON THE
OCEAN TO TONIGHT BASED ON LATEST WAVE WATCH GUIDANCE. WE KEPT THE
SAME STARTING TIME ON LOWER DELAWARE BAY. ARTHUR'S PASS ON THE
OCEAN IS GOING TO BE CLOSE TO TROPICAL STORM FLAGS. PLEASE KEEP
ABREAST TO THE LATEST INFORMATION. IT IS VERY STRONGLY RECOMMENDED
THAT SMALL CRAFT REMAIN IN PORT.

OUTLOOK...
FRIDAY NIGHT THROUGH SATURDAY MORNING...WINDS AND WAVES WILL
CONTINUE TO REMAIN ABOVE SMALL CRAFT CRITERIA AS HURRICANE ARTHUR
MAKES ITS WAY OFF TO THE NORTHEAST. WAVES OF 6 TO 8 FEET WILL
START TO SUBSIDE AND SHOULD START TO FALL BELOW 5 FEET BY SATURDAY
MORNING. WINDS WILL GUST AROUND 25 TO 30 KNOTS, POSSIBLE NEAR GALE
FORCE IN THE EXTREME SOUTHERN WATERS, AND THEN DIMINISH SATURDAY
MORNING. SMALL CRAFT CONDITIONS SHOULD ABATE BY LATE SATURDAY
MORNING. SHOULD THE TRACK OF ARTHUR PUSH A BIT TO THE WEST, BOTH
SEAS AND WINDS WILL INCREASE ON OUR AREA WATERS.

REST OF SATURDAY THROUGH SUNDAY...SUB-ADVISORY CONDITIONS ARE
EXPECTED ON THE AREA WATERS AS HIGH PRESSURE SLIDES ACROSS FROM
THE WEST AND THEN MOVES OFF TO OUR SOUTH AND EAST.

SUNDAY NIGHT THROUGH MONDAY...MAINLY SUB-ADVISORY CONDITIONS ARE
EXPECTED. BOTH WINDS AND WAVES WILL START TO INCREASE AND MAY
REACH SMALL CRAFT ADVISORY CRITERIA.

TUESDAY...WAVES WILL BE DIMINISHING THROUGH EARLY TUESDAY WITH
SUB-ADVISORY CONDITIONS EXPECTED.

&&

.HYDROLOGY...
A FLASH FLOOD WATCH REMAINS IN EFFECT FOR OUR ENTIRE FORECAST
AREA. IT COVERS LOCATIONS ALONG AND WEST OF THE I-95 CORRIDOR THRU
FRIDAY MORNING. THE WATCH IS VALID FOR SRN NJ AND THE DELMARVA
INTO FRIDAY AFTERNOON.

REASONS...SLOW MOVING SURFACE FRONT, 2.00" PW'S AHEAD AND ALONG
THE FRONT, AMPLE INSTABILITY, PRONOUNCED UPPER LEVEL DIVERGENCE,
AND THE POSSIBILITY OF A PREDECESSOR RAINFALL EVENT OR PRE.

TIMING...THE ABOVE INGREDIENTS COME TOGETHER THIS AFTERNOON INTO
TONIGHT. THE PW'S PEAK AROUND 2.00" AND THE RIGHT REAR QUAD OF THE
H25 JET IS OVERHEAD.

PREDECESSOR RAINFALL EVENTS (PRE)...AT THE MOMENT, THE GENERAL
QPF CONSENSUS FOR THE REGION IS BETWEEN ONE TO THREE INCHES OF
RAINFALL, FALLING THIS AFTERNOON INTO FRIDAY MORNING. THAT SAID,
IS IT KNOWN THAT NWP MODELS CAN UNDERESTIMATE HEAVY RAINFALL
ASSOCIATED WITH CONVECTION IN GENERAL AND PARTICULARLY WITH PRE.

DO WE HAVE PRE INGREDIENTS? YES WE DO. THIS INCLUDES THE RIGHT
REAR UPPER JET, BEING AHEAD OF THE MEAN LONG-WAVE TROUGH AXIS AT
THE MID-LEVELS, AND NEAR OR JUST WEST OF A LOW-LEVEL THETA-E RIDGE
AXIS. ADDITIONALLY, IF YOU LOOK AT THE CLIMATOLOGY OF PRE'S, MORE
OF THEM ARE TO THE LEFT OF A CYCLONE TRACK.

ANTECEDENT CONDITIONS WILL ALSO CONTRIBUTE TO AN ENHANCED FLASH
FLOOD RISK AS ONE TO THREE INCHES FELL FROM THUNDERSTORMS
WEDNESDAY AFTERNOON AND NIGHT ACROSS SOME OF THE AREA. THE GROUND
IS SATURATED FROM THIS PRIOR HEAVY RAINFALL...AND ADDITIONAL HEAVY
RAINFALL WILL RUNOFF.

ALL OF THE ABOVE, AT LEAST AT THIS TIME, SEEM TO BE COMING
TOGETHER OVER EASTERN PA THIS AFTERNOON/EVE AND NJ/DELMARVA TNGT.

ANOTHER CONCERN IS THAT THE RIDGING RIGHT TO THE WEST OF ARTHUR
COULD SLOW THE APPROACHING FRONT DOWN EVEN MORE THAN WHAT MODELS
ARE CURRENTLY SUGGESTING.

ON A POSITIVE NOTE, ONE OF THE MORE TYPICAL INGREDIENTS WE
COMMONLY SEE IN LARGE RAIN EVENTS ACROSS THE FALL LINE IS A
PERSISTENT SOUTHEAST FLOW WITH AN EXTENDED FETCH. IN THIS CASE, WE
ARE NOT SEEING THAT, ALTHOUGH THE WINDS SHOULD GO SOUTHEAST RIGHT
AHEAD OF THE FRONT AND THE BEST SURFACE CONVERGENCE.

RAINFALL...1.00 TO 3.00", BUT WITH PW'S AROUND 2.00" CAN
DEFINITELY SEE 4.00", MAYBE 5.00" IN SOME ISOLATED SPOTS.

FLOODING...AT THE MOMENT, WE ARE NOT EXPECTING FLOODING ON ANY
MAIN STEM RIVERS AT THIS TIME. OUR PRIMARY CONCERN LIES WITH THE
SMALLER CREEKS AND STREAMS AS WELL AS URBAN OR POOR DRAINAGE
AREAS.

&&

.RIP CURRENTS...
BECAUSE OF ARTHUR'S PASS COINCIDING WITH THE START OF THE HOLIDAY
WEEKEND, WE HAVE DECIDED TO ISSUE A HIGH SURF ADVISORY FOR FRIDAY
INTO FRIDAY NIGHT, EVEN IF WE WILL FALL A BIT SHORT OF CRITERIA.
WE ALSO ARE ANTICIPATING A HIGH RISK FOR RIP CURRENTS.

THIS POSES A HUGE CONCERN CONSIDERING THE LARGE NUMBERS OF
PEOPLE, INCLUDING THE LESS EXPERIENCED SWIMMERS, WHO WILL VENTURE
OUT DURING ONE OF THE BIGGEST BEACH WEEKENDS OF THE YEAR. THE
TRANQUIL WEATHER CONDITIONS ON LAND THIS WEEKEND COULD LEAD TO A
FALSE SENSE OF SAFETY IN THE WATERS.

RIP CURRENTS ARE LIFE-THREATENING IF YOU/RE NOT PREPARED TO
HANDLE THEM. FOR THE GREATEST CHANCE OF SAFETY...SWIM ONLY UNDER
THE WATCHFUL EYES OF LIFEGUARDS. OTHERWISE ANY OPPORTUNITY FOR
RESCUE CAN SUFFER FROM A MUCH GREATER RESPONSE DELAY AND BE FATAL.

COASTAL FLOODING, WE NEED THREE FOOT DEPARTURES TO REACH ADVISORY
STATEMENT LEVELS AND ARTHUR'S PASS APPEARS TO BE TOO FAST TO
INCREASE DEPARTURES TO THAT LEVEL. AS ALWAYS ANY WESTWARD
ADJUSTMENT WOULD INCREASE THE RISK.
