Special Weather Statement, NWS Philadelphia/Mount Holly

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MOUNT HOLLY NJ
248 PM EDT THU AUG 22 2013

.SYNOPSIS...
A COLD FRONT IN THE SAINT LAWRENCE RIVER VALLEY WILL MOVE SOUTHEAST
THIS AFTERNOON AND CROSS THE AREA DURING THE FIRST HALF OF THE DAY ON
FRIDAY. A LARGE AREA OF HIGH PRESSURE WILL BUILD INTO THE REGION
FROM THE NORTHWEST AND SLIDE OVER OUR AREA ON THE WEEKEND BEFORE
MOVING TO OUR SOUTH ON MONDAY. A WEAKENING COLD FRONT SHOULD MOVE
THROUGH THE MIDDLE ATLANTIC STATES AROUND WEDNESDAY.

&&

.NEAR TERM /UNTIL 6 AM FRIDAY MORNING/...
AN 18Z SURFACE ANALYSIS PLACED A TROUGH FROM NEAR NEW YORK CITY
SOUTHWESTWARD INTO VIRGINIA. A COLD FRONT WAS FROM SOUTHEASTERN
CANADA TO NEAR THE OHIO VALLEY THEN BACK INTO THE CENTRAL PLAINS. AN
UPPER AIR ANALYSIS SHOWED A TROUGH AXIS OVER THE MID ATLANTIC WITH A
STRONGER TROUGH FROM THE UPPER GREAT LAKES TO SOUTHEASTERN CANADA.

THE MAIN WEATHER FEATURE IS A LINGERING UPPER-LEVEL LOW THAT WILL
CONTINUE TO WEAKEN AS IT SHIFTS EAST THROUGH EARLY THIS EVENING. WE
THEN LOOK TO THE NORTHWEST AS A STRONG UPPER-LEVEL TROUGH WILL MOVE
ACROSS SOUTHEASTERN CANADA AND THE NORTHEAST THROUGH TONIGHT. THIS
WILL DRIVE A SURFACE COLD FRONT TOWARD AND EVENTUALLY ACROSS OUR
AREA LATE.

SOME SHORT WAVE ENERGY IN COMBINATION WITH A PLUME OF DEEPER
MOISTURE SHIFTING EAST IS HELPING TO AIDE IN ENOUGH LARGE SCALE LIFT
TO FOCUS SOME SHOWERS AND THUNDERSTORMS. THE MOST ACTIVE AND
ORGANIZED ACTIVITY HAS BEEN WITH A PRE-FRONTAL SURFACE TROUGH ALONG
THE INTERSTATE 95 CORRIDOR. THIS ACTIVITY WILL CONTINUE TO SHIFT
EASTWARD THROUGH THE REMAINDER OF THE AFTERNOON. BACK TO THE WEST,
SOME SUBSIDENCE IN THE WAKE OF THE INITIAL SHORT WAVES HAS KEPT NEW
DEVELOPMENT ISOLATED. HOWEVER, ADDITIONAL CONVECTION IS ONGOING
FARTHER TO THE WEST CLOSER TO THE ACTUAL COLD FRONT. WHILE
ADDITIONAL CONVECTION IS ANTICIPATED FOR AWHILE THIS EVENING, THE
MAIN ACTIVITY MAY END UP WEAKENING AS IT ARRIVES LATER THIS EVENING.
THEREFORE, WE LOWERED POPS THROUGH THE NIGHT WITH THE HIGHEST /CHC
RANGE/ ACROSS THE NORTHWEST ZONES AS INCOMING CONVECTION MAY ARRIVE
BEFORE DISSIPATING. THE POPS IN THE VERY NEAR TERM ARE BEING
ADJUSTED BASED ON RADAR TRENDS.

A PLUME OF PW VALUES NEAR 2 INCHES HAS RESULTED IN LOCALLY
TORRENTIAL RAIN WITH THE STRONGER CORES, WITH EVEN SOME FLOODING
REPORTED. A FEW THUNDERSTORMS COULD BE LOCALLY STRONG THROUGH EARLY
EVENING, HOWEVER THE LACK OF STEEPER MID LEVEL LAPSE RATES, STRONGER
LOW-LEVEL FLOW AND VERTICAL SHEAR SHOULD KEEP THE SEVERE
THUNDERSTORM THREAT ON THE RATHER LOW SIDE.

AS FOR LOW TEMPERATURES, WE MOSTLY USED A BLEND OF THE GFS/NAM MOS
WITH JUST SOME MINOR TWEAKS. THE HOURLY GRIDS WERE ADJUSTED BASED ON
THE LATEST OBSERVATIONS, THEN SOME BLENDING IN OF THE LAMP/LAV
GUIDANCE WAS USED TO ASSIST WITH THE TRENDS ESPECIALLY THROUGH MID
EVENING.

&&

.SHORT TERM /6 AM FRIDAY MORNING THROUGH 6 PM FRIDAY/...
AN UPPER-LEVEL TROUGH SETTLES INTO THE NORTHEAST AND THE MID
ATLANTIC AND EVEN AMPLIFIES SOME. AS THIS OCCURS, THE SURFACE COLD
FRONT WILL BE SETTLING SOUTH AND EAST OF OUR CWA. IT MAY TAKE A
LITTLE WHILE TO CLEAR OUR SOUTHERN ZONES, WHICH WILL ALLOW BETTER
MOISTURE TO REMAIN IN PLACE A BIT LONGER. OVERALL THOUGH, A DRIER
AIRMASS IS FORECAST TO ADVECT INTO THE AREA FROM THE NORTHWEST.

THE FORECAST SOUNDINGS REVEAL AS THE DRIER AIR ADVECTS FROM
NORTHWEST TO SOUTHEAST ACROSS THE CWA, A CAP DEVELOPS AS WELL. THIS
OCCURS SOONER UP NORTH AND LATER DOWN SOUTH. BASED ON THE POTENTIAL
FOR SOMEWHAT DEEPER MOISTURE HANGING ON ACROSS OUR FAR SOUTHERN
ZONES THROUGH MUCH OF THE AFTERNOON, WE HELD ONTO SOME SLIGHT CHC
POPS. AS THE DRIER AIR PUSHES FARTHER SOUTH, FORECAST SOUNDINGS
INDICATE THE INSTABILITY DROPS OFF BY LATER IN THE AFTERNOON. SOME
OF THE GUIDANCE INDICATES SOME CONVECTION MAY BE CLOSE TO OUR FAR
SOUTHERN ZONES, WHICH COULD BE AIDED BY THE DECENT POSITIONING OF AN
UPPER-LEVEL JET FOR A TIME. THEREFORE, WILL HANG ONTO SOME LOW CHC
POPS. THIS SAME UPPER-LEVEL JET FEATURE MAY ALSO TEND TO TOSS MORE
CIRRUS ACROSS AT LEAST THE SOUTHERN PARTS OF THE CWA.

AS SURFACE HIGH PRESSURE BUILDS ACROSS THE GREAT LAKES, THE PRESSURE
GRADIENT ACROSS OUR AREA IS FORECAST TO TIGHTEN SOME. THE FORECAST
SOUNDINGS INDICATE SOME DEEPER MIXING DEVELOPING, THEREFORE SOME
UPTICK IN THE WINDS ARE FORECAST ESPECIALLY FROM MIDDAY ON.

AS FOR HIGH TEMPERATURES, WE OPTED TO START WITH A BLEND OF THE
GFS/NAM MOS THEN MADE SOME TWEAKS. THE FLOW IS NORTH-NORTHWEST SO
THIS MAY ALLOW THE COASTAL PLAIN ESPECIALLY TO GET WARMER, PENDING
CLOUDS ARE AT A MINIMUM.

&&

.LONG TERM /FRIDAY NIGHT THROUGH WEDNESDAY/...
THE GFS INITIALIZATION LOOKED BETTER THAN THE WRF-NMMB AT 500MB AND
850MB. THE LATTER LOOKED BETTER OVER THE LOCAL AREA AT 925MB, BUT
UPWIND THE GFS LOOKED BETTER. THE GFS WAS PART OF WPC'S PREFERENCE
AND THUS WAS GIVEN MORE WEIGHT THAN AVERAGE THROUGH THE LONG TERM.
THAT BEING SAID, THE MODEL SPREAD TOWARD THE END OF THE LONG TERM
REMAINS PRETTY LARGE AND WE WENT MORE ALONG THE LINES OF PRESERVING
CONTINUITY UNTIL A MORE CONVERGENT SOLUTION EVOLVES.

A CLEAR NIGHT IS EXPECTED ON FRIDAY NIGHT. THERE SHOULD BE TOO
MUCH OF AN INITIAL GRADIENT FOR AN IDEAL RADIATIONAL COOLING
NIGHT. THE TRAJECTORY AROUND THE SURFACE HIGH ALSO CASTS SOME
DOUBT FOR THE EASTERN PART OF OUR CWA. THUS WE WERE MORE BULLISH
ABOUT MINIMUM TEMPS NORTHWEST OF I95 THAN SOUTHEAST.

WE ARE SLIGHTLY LESS CONFIDENT ABOUT THE AMOUNT OF SUNSHINE ON
SATURDAY VS SUNDAY AS THE FLOW AROUND THE SURFACE HIGH IS
STRONGER ONSHORE SATURDAY THAN SUNDAY WHEN IT BECOMES VERY LIGHT.
RIGHT NOW THE GFS FCST MOISTURE IS EXTREMELY LOW EVEN WITH THE
OCEANIC TRAJECTORY. THE COUPLE OF HUNDREDTHS THE MODEL
MANUFACTURES SEEMS TIED TO DEW POINTS WHICH SHOULD VERIFY TOO
HIGH. EITHER WAY TEMPERATURES SHOULD AVERAGE AT OR LOWER THAN
NORMAL WITH LOW HUMIDITY LEVELS BOTH DAYS. THE SUNDAY MORNING MINS
FOLLOW THE MORE TRADITIONAL RADIATIONAL COOLING PATTERN IN NON
URBAN AREAS WITH MINS IN INTERIOR DELMARVA LOWER THAN PHL AND THE
PINE BARRENS COMPARABLE TO OUTLYING AREAS NW OF I95.

THEN WE WILL START THE AIR MASS MODIFICATION PROCESS ON MONDAY. THE
00Z MODEL SUITE WAS SLOWER IN BRINGING BACK SUFFICIENT MOISTURE FOR
PCPN, SO WE REMOVED OUR LOW CHANCES FOR MONDAY. THEN THE REST OF THE
LONG TERM WE KEPT CLOSE TO CONTINUITY. THE MODELING TREND HAS
BEEN LEANING AWAY FROM THE HEAT RIDGE MAKING IT OUT OF THE CENTRAL
MISSISSIPPI AND LOWER OHIO VALLEYS. THIS WOULD LEAVE OUR CWA IN
THE RING OF FIRE AROUND THIS SYSTEM WITH FRONTAL BOUNDARIES TRYING
TO WORK THEIR WAY THROUGH OUR CWA. WHILE WE SHOULD GET WARMER AND
MORE HUMID, THE CURRENT MODELING TREND MIGHT PREVENT MOST OF US
FROM REACHING 90F AND REMAINING IN THAT RING WILL GIVE US SHOWER
AND THUNDERSTORM CHANCES BOTH TUESDAY AND WEDNESDAY.

&&

.AVIATION /19Z THURSDAY THROUGH TUESDAY/...
THE FOLLOWING DISCUSSION IS FOR KPHL, KPNE, KTTN, KABE, KRDG,
KILG, KMIV, KACY AND SURROUNDING AREAS.

REST OF THIS AFTERNOON...VFR OVERALL. SOME SHOWERS AND THUNDERSTORMS
WILL CONTINUE TO TRACK EASTWARD ACROSS MUCH OF THE AREA. THE
GREATEST COVERAGE IS FROM KTTN TO KPHL AND KILG, HOWEVER SOME
ADDITIONAL DEVELOPMENT IS OCCURRING FARTHER TO THE WEST. ANY SHOWERS
AND THUNDERSTORMS WILL GREATLY REDUCE THE LOCAL VISIBILITY FOR A
TIME DUE TO HEAVY DOWNPOURS. SOUTHWESTERLY WINDS GENERALLY AROUND
10 KNOTS.

TONIGHT...VFR OVERALL, HOWEVER LOCALLY REDUCED VISIBILITIES WITH SOME
LINGERING SHOWERS AND THUNDERSTORMS. IT APPEARS ANY SHOWERS AND
THUNDERSTORMS ARE MAINLY DURING THE EVENING. THE COLD FRONT WILL
ARRIVE LATER, ALLOWING THE WEST-SOUTHWEST WINDS TO BECOME NORTHWEST
LATE. THE WINDS SPEEDS ARE FORECAST TO BE LESS THAN 10 KNOTS. AS THE
LOW-LEVEL MOISTURE LINGERS, SOME LOCALIZED FOG IS POSSIBLE AND THIS
WAS HINTED AT SOME OF OUR MORE FOG PRONE TERMINALS.

FRIDAY...PERHAPS LOCAL MVFR DUE TO FOG EARLY, OTHERWISE VFR.
NORTH-NORTHWEST WINDS AROUND 10 KNOTS, WITH SOME LOCAL GUSTS TO
AROUND 18 KNOTS IN THE AFTERNOON.

OUTLOOK...
FRIDAY NIGHT THROUGH MONDAY...PREDOMINATELY VFR CONDITIONS. SOME
MORNING FOG POSSIBLE SUNDAY AND MONDAY AT MORE RURAL AIRPORTS.
MORNING VISIBLE SATELLITE PHOTOS WILL LIKELY SHOW FOG WITHIN SOME
OF THE LARGER RIVER VALLEYS.

&&

.MARINE...
SUB-ADVISORY CONDITIONS WILL CONTINUE ACROSS THE AREA WATERS.

WINDS WILL BE OUT OF A SOUTHERLY DIRECTION WITH SPEEDS AROUND 10
KNOTS. WINDS WILL START TO TURN MORE TO THE WEST...THEN NORTHWEST
AS A COLD FRONT APPROACHES AND THEN CROSSES THE WATERS LATE
TONIGHT INTO FRIDAY MORNING. SHOWERS AND THUNDERSTORMS WILL BE
AROUND THE REGION THROUGH THE DAY WHICH MAY CAUSE LOCALLY HIGHER
SEAS AND WIND GUSTS.

OUTLOOK...
SUB SMALL CRAFT ADVISORY CONDITIONS ARE EXPECTED TO CONTINUE THROUGH
THE OUTLOOK PERIOD. THE LOWEST CONFIDENCE ABOUT THIS OUTLOOK IS ON
CALENDAR DAY SATURDAY AS THERE SHOULD BE AN ONSHORE FLOW BEFORE THE
HIGH PRESSURE SYSTEM BUILDS IN DEEPER INTO OUR MARINE AREA. BOTH
WINDS AND SEAS MIGHT COME CLOSE TO ADVISORY CRITERIA SATURDAY ON
THE OCEAN.

AFTER THAT AS THE HIGH PRESSURE SYSTEM SETTLES SOUTHWARD ON SUNDAY
INTO MONDAY, THERE IS GREATER CONFIDENCE ABOUT REMAINING BELOW SMALL
CRAFT ADVISORY CONDITIONS.
