AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MOUNT HOLLY NJ
342 PM EDT MON AUG 16 2010

.SYNOPSIS...
A COLD FRONT MOVING SLOWLY SOUTHEAST ACROSS THE AREA TONIGHT WILL
TRIGGER SHOWERS AND THUNDERSTORMS. THE FRONT WILL BECOME NEARLY
STATIONARY ACROSS SOUTHERN DELAWARE ON TUESDAY. A WAVE OF LOW
PRESSURE WILL MOVE NORTHEAST ALONG THE FRONT WEDNESDAY AND
WEDNESDAY NIGHT RESULTING IN MORE RAIN. WEAK HIGH PRESSURE WILL
COVER THE AREA ON THURSDAY AND FRIDAY BUT ANOTHER FRONTAL SYSTEM
MAY BRING MORE PRECIP FOR THE WEEKEND.

&&

.NEAR TERM /UNTIL 6 AM TUESDAY MORNING/...
THUNDERSTORM ACTIVITY IS GRADUALLY INCREASING ALONG AND AHEAD OF
THE COLD FRONT FROM NE THROUGH S-CNTRL PA AND INTO NRN VA. THE AIR
MASS AHD OF THE FRONT IS MODERATELY UNSTABLE WITH LI/S OF -4 TO
-8. TSTMS SHOULD CONTINUE TO INCREASE AND SPREAD EWD FOR THE
REMAINDER OF THE AFTN AND INTO THE EVE. WW 619 REMAINS IN EFFECT
UNTIL 900 PM FOR PHILA AND AREAS GENERALLY N AND W. ESSENTIALLY
THE ENTIRE CWA REMAINS IN A SLIGHT RISK.

&&

.SHORT TERM /6 AM TUESDAY MORNING THROUGH THURSDAY/...
THE COLD FRONT IS FCST TO MOVE SLOWLY SEWD THRU THE FCST AREA
TONIGHT AND BECOMED Q-STNRY ACRS SRN DELAWARE AND PSBLY SRN NJ BY
TUE MORNING. THE FRONT SHOULD BECOME LESS ACTIVE BY THEN WITH A
MORE STABILIZED AMS AND NO OBVIOUS UPPER-LVL FORCING IN THE AREA.
HWVR...WITH CONTD LOW-LVL CNVGNC IT SEEMS PRUDENT TO KEEP AT LEAST
A LOW CHC POP OVER DELMARVA FOR TUE.

TUE NIGHT SHOULD SEE SLIGHTLY HIGHER POPS OVER SRN AREAS AS A WAVE
STARTS TO DVLP ON THE FRONT. THE MAIN EFFECTS THO SHOULD BE ON WED
AND WED NIGHT AS THE WAVE OF LOW PRESSURE MOVES ACROSS THE AREA.
THERE ARE SOME DIFFERENCES IN LOCATION WITH GFS AND LATEST ECMWF
BEING FURTHER S THAN THAN THE NAM...BUT EITHER WAY THE FCST AREA
SHOULD HOPEFULLY SEE SOME NEEDED RAIN FROM THIS SYSTEM.

DEPENDENT ON TIMING...SOME PRECIP MAY LINGER OVER THE AREA THU
MORNING BUT MUCH OF THE DAY SHOULD BE DRY WITH NEAR NORMAL TEMPS.

A BLEND OF MAV/MET GUIDANCE WAS GENERALLY USED FOR MAX/MIN TEMPS
DURING THIS PERIOD.

&&

.LONG TERM /THURSDAY NIGHT THROUGH MONDAY/...
OUR CWA IS EXPECTED TO BE MORE DEEPLY ENSCONCED IN THE WESTERLY
FLOW THROUGH THIS PERIOD. THE 500MB HEAT RIDGE WILL REMAIN EITHER
IN THE SOUTHERN ROCKIES OR CENTRAL PLAINS THROUGH THE PERIOD.
WHILE OUR WEATHER WILL NOT BE COOLER THAN NORMAL, DISTURBANCES
WITHIN THE WESTERLY/NORTHWESTERLY FLOW WILL GIVE US SOME
LEGITIMATE PRECIPITATION CHANCES.

THERE WERE MODEL TIMING DIFFERENCES WRT TO THE WAVE ON THE FRONT IN
THE SHORT TERM, BUT OTHER THAN THE CAN GGEM, ALL OF THEM HAVE THE
LOW PRESSURE SYSTEM SUFFICIENTLY OFFSHORE TO START THU NGT AS DRY. A
SECONDARY COLD FRONT IS FORECAST TO MOVE THROUGH THE CWA ON FRIDAY.
MODEL FCST SOUNDINGS THOUGH ARE TOO DRY AND WE ARE NOT CARRYING ANY
PCPN CHANCES.

THE NEXT PCPN CHANCES ALONG WITH MORE HUMID WEATHER COME FRIDAY
NIGHT INTO SATURDAY AS A WARM FRONT IS FORECAST TO MOVE THROUGH OUR
CWA. PRECIP THREAT WILL CONTINUE INTO SUNDAY PRECEDING AND
ACCOMPANYING A COLD FRONT FROM THE MIDWEST. AS OF TODAY IT IS
POSITIONED FAIRLY WELL TO MAXIMIZE SHRA AND TSRA CHANCES ACROSS THE
NW HALF OF OUR CWA.

THEN FAIR AND DRIER WEATHER SHOULD RETURN ON MONDAY. THE LATEST
ECMWF IS MUCH SLOWER WITH THE SUNDAY/MONDAY EVOLUTION OF THE COLD
FRONT. OVER THE LAST COUPLE OF MONTHS IF IT HAS HAD A BIAS, ITS
BEEN A SLOW TIMING ONE. THE LATEST UKMET IS MORE LINE WITH THE GFS
THAN THE ECMWF. THE FCST 500MB FLOW IS MORE NW THAN IT WILL BE AT
THE START OF THE LONG TERM. THIS SHOULD BRING RELATIVELY DRIER, LESS
HUMID AIR INTO OUR CWA FOR THE START OF THE NEXT WORK WEEK IF NOT
MONDAY, THEN TUESDAY.

WE DID NOT SWAY MUCH FROM MEX OR HPC GUIDE WRT TO TEMPS. WANT TO SEE
IF WE GET SOME BENEFICIAL OR MAYBE TOO MUCH OF A BENEFICIAL RAIN
OVER THE NEXT COUPLE OF DAYS. WITHOUT IT AND AS LONG AS IT HAS NOT
BEEN COMPLETELY CLOUDY, MAX TEMPS HAVE BEEN RUNNING TOWARD THE HIGH
END OF THE GUIDANCE ENVELOPE.

&&

.AVIATION /19Z MONDAY THROUGH SATURDAY/...
A COLD FRONT ENTERING THE REGION AT MID AFTERNOON WILL MOVE
THROUGH TONIGHT BEFORE STALLING IN OUR VICINITY TUESDAY AND
WEDNESDAY. SOME LINGERING MVFR CLOUDS AROUND THIS AFTERNOON AS
PLENTY OF MOISTURE IN THE LOWER LEVELS HAS PREVENTED THIS FROM
COMPLETELY MIXING OUT. THE LAST OF THE IMPROVEMENTS ARE AT KRDG
AND KABE WHERE SOME HAZE HAS ALSO BEEN REPORTED. OVERALL, CEILINGS
ARE OR ARE EXPECTED TO BECOME VFR. THE MAIN CONCERN IS THE TIMING
AND COVERAGE OF THUNDERSTORMS THROUGH THIS EVENING. THE COLD FRONT
WILL DRIVE EASTWARD, AND AS OF 1900Z A BROKEN LINE OF SHOWERS AND
THUNDERSTORMS WAS FROM SOUTHEASTERN NEW YORK SOUTHWESTWARD TO
WESTERN MARYLAND. THIS ACTIVITY IS MOVING EASTWARD AND THERE
SHOULD BE SOME FILLING IN OF THE LINE AS IT ENCOUNTERS MORE
UNSTABLE AIR. THE LINE MAY NOT BE COMPLETELY SOLID THOUGH WITH
PERHAPS TWO AREAS OF BETTER ORGANIZATION. ONE UP ACROSS
SOUTHEASTERN NEW YORK STATE TO SOUTHWESTERN NEW ENGLAND AND THE
OTHER SOUTHWEST OF KPHL TO THE KDCA AREA. WE UTILIZED A TEMPO
GROUP TO INDICATE OUR BEST ESTIMATE OF TIMING AT THIS POINT AT ALL
TERMINALS EXCEPT KMIV AND KACY WHERE A CB MENTION WAS KEPT. THERE
IS SOME HIGHER CONFIDENCE THE FARTHER WEST ONE GOES. SOME STORMS
WILL BE CAPABLE OF PRODUCING GUSTY WINDS AND HEAVY RAIN. A SEA
BREEZE TYPE BOUNDARY IS SHOWING UP ON SATELLITE AND RADAR IMAGERY
ACROSS FAR EASTERN NEW JERSEY. AS OF NOW, WE ARE NOT ANTICIPATING
ANY CONVECTION FORMING ON THIS AND IMPACTING KACY OR KMIV.

AS THE FRONT SLIDES THROUGH, ANY CONVECTION SHOULD TEND TO WANE
THROUGH THE EVENING AS THE ENERGY DECREASES. SOME OF THE MODEL
GUIDANCE SUGGEST THAT SOME SHOWERS AND THUNDERSTORMS LINGER THROUGH
A GOOD PART OF THE NIGHT, HOWEVER THAT MAY BE OVERDONE. A SOUTHWEST
WIND AROUND 10 KNOTS WILL BECOME LIGHTER AND VARIABLE DURING THE
NIGHT. ANY TERMINAL THAT IS ABLE TO HOLD ONTO SOME WIND, SHOULD HAVE
A WIND SHIFT TO THE NORTH BEHIND THE FRONT. THE LOW-LEVEL MOISTURE
MAY HANG ON FOR AWHILE TONIGHT INTO TUESDAY, THEREFORE CARRIED A BIT
OF FOG AT SOME OF THE MORE PRONE TERMINALS. DEPENDING ON WHERE THE
FRONT GETS HUNG UP TUESDAY, THERE COULD BE A SHOWER OR THUNDERSTORM
/MAINLY CLOSET TO KACY AND KMIV. A NORTHERLY FLOW TO START TUESDAY
SHOULD INCREASE A LITTLE AND SHIFT TO THE NORTHWEST. THE WINDS LOOK
LIGHT ENOUGH WHERE SOME TERMINALS MAY HAVE THE WIND SHIFT TO THE
SOUTHWEST AND SOUTH DURING THE AFTERNOON /I.E. KACY AND KMIV/. SOME
CUMULUS SHOULD DEVELOP TUESDAY ESPECIALLY THE FARTHER SOUTH WHERE
DEEPER MOISTURE LINGERS LONGER, WITH PERHAPS SOME MID TO HIGH CLOUDS
ABOVE.

OUTLOOK...
THE FRONTAL BOUNDARY IS STALLED NEARBY THROUGH WEDNESDAY AND MAY BE
ABLE TO FOCUS SOME SHOWERS AND THUNDERSTORMS, MAINLY SOUTH OF ALL OF
OUR TERMINALS. AN AREA OF LOW PRESSURE HOWEVER IS FORECAST TO
DEVELOP AND TRACK ALONG THE FRONT WEDNESDAY INTO THURSDAY. THIS MAY
PRODUCE A MORE WIDESPREAD RAIN WITH EMBEDDED THUNDERSTORMS ACROSS A
PORTION OF THE AREA, WITH AREAS OF HEAVY RAIN POSSIBLE. THERE IS
SOME UNCERTAINTY HOWEVER ON THE TIMING AND LOCATION OF THE MORE
ORGANIZED CORRIDOR OF PRECIPITATION. A WEAK AREA OF HIGH PRESSURE
THEN BUILDS IN FOR FRIDAY, HOWEVER A FRONTAL BOUNDARY MAY SETTLE
INTO OUR AREA FRIDAY NIGHT AND LINGER SATURDAY.

&&

.MARINE...
A COLD FRONT WILL BE ARRIVING IN OUR AREA TONIGHT WITH A
SOUTHERLY FLOW AHEAD OF IT. THE LOW-LEVEL FLOW HAS INCREASED AHEAD
OF THE FRONT, HOWEVER AN INVERSION OVER THE WATER AS HOTTER AIR
ADVECTS IN IS KEEPING THE SURFACE WINDS IN THE 10 TO 15 KNOT
RANGE. SOME GUSTS HAVE BEEN APPROACHING 20 KNOTS, HOWEVER THAT
SHOULD BE THE UPPER END OF THE GUSTINESS THROUGH TONIGHT WITHIN
THE SYNOPTIC REGIME. SOME SHOWERS AND THUNDERSTORMS SHOULD CROSS
THE AREA TONIGHT AS THE FRONT SETTLES THROUGH, AND PERHAPS LOCALLY
GUSTY WINDS MAY RESULT FROM THE CONVECTION. THE FRONT LOOKS TO
STALL NEARBY ESPECIALLY ACROSS OUR SOUTHERN WATERS TUESDAY AND
WEDNESDAY. THE TRUE DEFINITION OF THE FRONT WILL DETERMINE THE
OVERALL WIND DIRECTION, HOWEVER A SHIFT TO THE NORTHWEST SHOULD
OCCUR BEHIND THE FRONT MAINLY ACROSS THE NORTHERN COASTAL WATERS
AND PARTS OF DELAWARE BAY LATE TONIGHT AND TUESDAY MORNING.
OTHERWISE, THE FLOW APPEARS LIGHT ENOUGH TUESDAY WHERE A SOUTHERLY
WIND BECOMES DOMINANT AND IT COULD BE ENHANCED SOME NEARSHORE BY A
SEA BREEZE CIRCULATION.

AN AREA OF LOW PRESSURE IS FORECAST TO TRACK ALONG THIS FRONT
WEDNESDAY INTO THURSDAY. THIS SURFACE LOW DOES NOT APPEAR TO BE REAL
VIGOROUS, HOWEVER THE LOW-LEVEL FLOW WILL TURN ONSHORE AHEAD OF IT.
ATTM, WE ARE NOT ANTICIPATING THE WINDS TO RAMP UP TO ADVISORY
CRITERIA AND THE LENGTH OF TIME THAT THE ONSHORE FLOW OCCURS APPEARS
SHORT ENOUGH TO NOT BUILD THE SEAS TO MUCH. AS A RESULT, WE
MAINTAINED CONDITIONS BELOW ADVISORY CRITERIA THROUGH THE PERIOD.
THE SURFACE LOW MAY BRING WIDESPREAD SHOWERS AND THUNDERSTORMS TO
THE AREA, WITH THE POTENTIAL FOR A STEADIER RAIN WEDNESDAY INTO
THURSDAY. THERE ARE HOWEVER SOME TIMING AND PLACEMENT UNCERTAINTIES
REGARDING THE MAIN PRECIPITATION. HIGH PRESSURE RETURNS FOR FRIDAY,
ALTHOUGH A FRONTAL BOUNDARY MAY SETTLE INTO THE AREA FRIDAY NIGHT
AND SATURDAY.
