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

.SYNOPSIS...
A COLD FRONT OVER NORTHWEST NEW YORK AND PENNSYLVANIA WILL MOVE
SOUTHEAST ACROSS THE REGION THIS EVENING AND TONIGHT. THE FRONT
WILL BE PRECEDED BY SCATTERED SHOWERS AND THUNDERSTORMS. HIGH
PRESSURE WILL BUILD IN BEHIND THE FRONT AND BRING FAIR WEATHER FOR
FRIDAY AND THROUGH THE WEEKEND. NEXT WEEK THE HIGH WILL SETTLE TO
OUR SOUTEAST RESULTING IN MORE HUMID CONDITIONS AND THE CHANCE FOR
SHOWERS AND THUNDERSTORMS.

&&

.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 TO OUR 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 EASTWARD 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 MOSTLY ISOLATED. HOWEVER, ADDITIONAL CONVECTION
IS ONGOING FARTHER TO THE WEST /ORGANIZING INTO A LINE/ CLOSER TO
THE ACTUAL COLD FRONT. WHILE ADDITIONAL CONVECTION IS ANTICIPATED
LATE THIS AFTERNOON AND 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/ ENDING
UP ACROSS THE NORTHWEST ZONES AS INCOMING CONVECTION MAY ARRIVE
BEFORE EVENTUALLY DISSIPATING. THE POPS IN THE VERY NEAR TERM WERE
ADJUSTED BASED ON RADAR TRENDS. SOME INCREASE IN THE POPS MAY BE
NEEDED ESPECIALLY ACROSS THE NORTHWEST ZONES PENDING INCOMING
CONVECTION.

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 WILL TEND TO 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 SLIGHT
CHC POPS ALTHOUGH THESE WERE TRIMMED BACK A BIT MORE. THIS SAME
UPPER-LEVEL JET FEATURE MAY ALSO TEND TO TOSS MORE HIGH LEVEL CLOUDS
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 THURSDAY/...
FOR THE EXTENDED PERIOD...A STRONG UPPER RIDGE STAYS IN PLACE OVER
THE CENTRAL U.S. FOR THE ENTIRE PERIOD RESULTING IN NW FLOW ALOFT
OVER THE MID ATLANTIC REGION. FOR SAT AND SUN...THE FLOW IS ANTI-
CYC AND SFC HIGH PRESS SHIFTS SEWD FROM THE LOWER GRTLKS TO THE
MID ATLANTIC COAST. LOW RH AND GENERALLY DOWNWARD VV WILL YIELD
FAIR SKIES AND LITTLE OR NO CHC OF PRECIP. THE DRIER AMS WITH
CLEAR SKIES AND LIGHT WINDS WILL ALLOW GOOD RADIATIONAL COOLING
SATURDAY AND SUNDAY NIGHT WITH SMWHAT BELOW NORMAL MIN TEMPS...
HWVR DAYTIME MAX TEMPS SHOULD BE NEAR NORMAL FOR THIS TIME OF
YEAR. THIS PATN SHOULD CONTINUE INTO MONDAY WITH SIMILAR PLEASANT
CONDITIONS.

STARTING MONDAY NIGHT...THE HIGH PRESSURE WILL SHIFT TO OUR SE
ALLOWING FOR SW LOW-LVL WINDS AND INCREASING MOISTURE. ALSO...A
SHRTWV TROF IS FCST TO MOVE SEWD ACROSS THE AREA WHICH MAY KICK
OFF SCT SHRA/TSRA. THE ECMWF IS MORE ROBUST WITH THIS FEATURE. OUR
POP FCST HAS A SLGT CHC FOR PRECIP MON NIGHT INTO TUE AS A
COMPROMISE.

ANOTHER SHRTWV TROF IN THE NW FLOW IS FCST TO AFFECT THE AREA FOR
WED WITH MORE SHRA/TSRA. THE GFS SEEMS A BIT OVERDONE WITH THIS
ONE WITH AN UNSEASONABLY STRONG SFC LOW AND LOTS OF PRECIP IN A
SITN WHERE IT IS DFCLT TO TAP INTO MUCH MSTR. THE TIMING IS ALSO
UNCERTAIN BUT FOR NOW WE ARE ASSUMING THE SYS WILL MOVE PAST BY
EARLY THURS SO POPS ARE LOW FOR THURS DAYTIME.

&&

.AVIATION /20Z THURSDAY THROUGH TUESDAY/...
REST OF THIS AFTERNOON...VFR OVERALL. SOME SHOWERS AND
THUNDERSTORMS WILL CONTINUE TO TRACK EASTWARD ACROSS THE AREA. THE
GREATEST COVERAGE IS SHIFTING EAST OF 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 NEAR 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 UP
TO 20 KNOTS IN THE AFTERNOON.

OUTLOOK...
SATURDAY NIGHT THROUGH TUESDAY...PREDOMINATELY VFR CONDITIONS ARE
EXPECTED. SOME MORNING FOG POSSIBLE EARLY SUNDAY AND MONDAY AT
MORE RURAL AIRPORTS. SCATTERED SHRA/TSRA ARE POSSIBLE MONDAY NIGHT
AND TUESDAY WITH LOCALLY REDUCED CIGS/VSBYS.

&&

.MARINE...
THE CONDITIONS ARE EXPECTED TO REMAIN BELOW SMALL CRAFT ADVISORY
CRITERIA THROUGH FRIDAY. A COLD FRONT WILL ARRIVE LATE TONIGHT,
THEN SETTLE SOUTH AND EAST OF THE AREA FRIDAY MORNING. THE
SOUTHERLY FLOW WILL CONTINUE AHEAD OF THE FRONT, THEN SHIFT TO THE
WEST LATE TONIGHT. SOME SHOWERS AND THUNDERSTORMS WILL BE AROUND
THROUGH THIS EVENING, AND A FEW STORMS MAY PRODUCE LOCALLY GUSTY
WINDS. AS HIGH PRESSURE BUILDS ACROSS THE GREAT LAKES FRIDAY, THE
PRESSURE GRADIENT WILL TIGHTEN SOME ACROSS OUR AREA. HOWEVER
DESPITE THE WINDS TURNING MORE FROM THE NORTH, THE OVERALL SPEEDS
ARE FORECAST TO REMAIN WELL BELOW ADVISORY CRITERIA.

OUTLOOK...
NORTHEAST WINDS ON SATURDAY COULD RESULT IN SEAS APPROACHING 5
FEET ON SATURDAY INTO SAT EVENING. OTRW SCA CONDITIONS ARE NOT
EXPECTED THROUGH TUESDAY...ALTHOUGH SW WINDS WILL INCREASE ON
TUESDAY.

&&

.HYDROLOGY...
SCATTERED SHOWERS AND THUNDERSTORMS WILL CONTINUE TO DEVELOP THIS
AFTERNOON AND EVENING AND PRODUCE LOCALLY HEAVY DOWNPOURS AND
LOCALIZED FLOODING. THESE MAY REQUIRE FURTHER ISSUANCE OF FLOOD
ADVISORIES AND WARNINGS...BESIDES THOSE CURRENTLY IN EFFECT...UNTIL
THE COOL FRONT PASSES SOMETIME OVERNIGHT.
