AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MOUNT HOLLY NJ
402 PM EDT WED JUL 14 2010

.SYNOPSIS...
LOW PRESSURE OVER SOUTHERN NEW JERSEY THIS AFTERNOON WILL MOVE
SLOWLY EAST AND OFF THE COAST TONIGHT. WEAK HIGH PRESSURE WILL
MOVE OVER THE REGION ON THURSDAY AND THEN MERGE WITH THE SEASONAL
BERMUDA HIGH ON FRIDAY. A COLD FRONT WILL APPROACH ON FRIDAY
NIGHT THEN BECOME NEARLY STATIONARY OVER THE AREA FOR THE WEEKEND.

&&

.NEAR TERM /UNTIL 6 AM THURSDAY MORNING/...
LOW PRESSURE HAS BEEN MOVING SLOWLY EASTWARD ACROSS THE FORECAST
AREA TODAY. HEAVY SHOWERS AND THUNDERSTORMS HAVE BEEN BEEN
DEVELOPING IN A DEFORMATION ZONE JUST NW OF THE LOW CENTER. THESE
STORMS ARE SLOW MOVING IN A VERY MOIST AIR MALL AND ARE PRODUCING
LOCALLY HEAVY RAINFALL UP TO 2 INCHES PER HOUR. SEVERAL FLOOD
WARNINGS AND ADVISORIES ARE IN EFFECT AS OF THIS WRITING. IT LOOKS
LIKE STORMS WILL CONTINUE PAST 4 PM AND INTO THE EVENING SO THE
FLOOD WATCH HAS BEEN EXTENDED UNTIL 1000 PM. LATER THIS EVENING
THE LOW SHOULD MOVE OFFSHORE AND THE HEAVY TSTORMS SHOULD DIE OFF.

SKIES SHOULD AT LEAST PARTIALLY CLEAR OVERNIGHT AND WITH RATHER
LIGHT WINDS...PLACES THAT RECEIVED RAIN OVER THE PAST COUPLE OF
DAYS MAY SEE SOME AREAS OF FOG DEVELOP.

&&

.SHORT TERM /6 AM THURSDAY MORNING THROUGH SATURDAY/...
FOR THURSDAY...THE LOW PRESSURE SHOULD CONTINUE TO DRIFT AWAY FROM
THE COAST AND WEAK HIGH PRESSURE WILL BUILD IN. IT WILL BE VERY
WARM AND HUMID...BUT FCST HIGH TEMPS NEAR 90 AND DEWPTS IN THE
MID TO UPPER 60S YIELD HEAT INDICES ONLY IN THE LOWER 90S...THUS A
HEAT ADVISORY DOES NOT SEEM NECESSARY AND THE HEAT WATCH HAS BEEN
CONTNUED ONLY FOR FRIDAY.

FOR FRIDAY...THE BERMUDA HIGH WITH SW FLOW BECOMES RE-ESTABLISED
OVER THE AREA. TEMPS AND DEWPTS WILL BE SLIGHTLY HIGHER THAN THURS
AND HEAT INDICES ARE FCST AROUND 100. THUS THE HEAT WATCH REMAINS
IN EFFECT FOR FRIDAY. A COLD FRONT WILL BE APPROACHING FROM THE NW
AND THERE IS AT LEAST A SLIGHT CHANCE FOR LATE AFTN OR EVENING
TSTORMS OVER NERN PA AND NWRN NJ.

FOR FRIDAY NIGHT AND SATURDAY...THE COLD FRONT IS FCST TO PUSH
SEWD ACROSS THE FCST AREA AND THEN STALL SOMEWHERE AROUND THE
MASON-DIXON LINE. CLOUDINESS ASSOCIATED WITH THE FRONT SHOULD
RESULT IN SLIGHTLY COOLER TEMPS ON SATURDAY BUT A CONTINUING
CHANCE OF SHOWERS AND THUNDERSTORMS.

&&

.LONG TERM /SATURDAY NIGHT THROUGH WEDNESDAY/...
A FRONTAL ZONE WILL REMAIN OVER OR NEAR OUR AREA UNTIL THE END OF
THIS PERIOD. THIS WILL MEAN THAT OUR FORECAST WILL HAVE CHANCE OR
SLIGHT CHANCE POPS FOR AN EXTENDED PERIOD OF TIME. I DID MANAGE TO
DROP THE MENTION OF PRECIPITATION FOR LATE SUNDAY NIGHT INTO
MONDAY MORNING AND THEN AGAIN LATE TUESDAY NIGHT AND WEDNESDAY, AS
HIGH PRESSURE TRIES TO PUSH IN FROM THE NORTHWEST. OBVIOUSLY, AT
OTHER TIMES, IT WILL NOT BE CONSTANTLY RAINING, BUT THERE WILL BE
A THREAT FOR A SHOWER OR THUNDERSTORM. TEMPERATURES WILL REMAIN ON
THE WARM SIDE THROUGH THE PERIOD WITH DAYTIME HIGHS IN THE 80S TO
LOWER 90S AND OVERNIGHT LOWS IN THE 60S TO LOWER AND MID 70S.

&&

.AVIATION /20Z WEDNESDAY THROUGH MONDAY/...
THE FOLLOWING DISCUSSION IS FOR KPHL, KPNE, KTTN, KABE, KRDG,
KILG, KMIV, KACY AND SURROUNDING AREAS.

AN AREA OF LOW PRESSURE REMAINS OVER THE REGION AND IS VERY
LETHARGICALLY MOVING EASTWARD. A COPIOUS AMOUNT OF MOISTURE IS
ASSOCIATED WITH THIS SYSTEM AND HAS BEEN DUMPING SAID MOISTURE
ACROSS MOST OF OUR TAF SITES THIS AFTERNOON. A LINE OF STRONG
THUNDERSTORMS HAS DEVELOPED OUT AHEAD OF THE CENTER OF THE LOW,
SOUTH OF PHL, AND ARE CURRENT TREKKING TO THE NORTH
NORTHWEST...AROUND THE LOW PRESSURE CIRCULATION. TEMPO GROUPS HAVE
BEEN ADDED TO THE FORECAST TAFS FOR THE NEXT COUPLE OF HOURS AS
VSBYS AND CIGS, PLUS WEATHER, ARE EXPECTED TO CHANGE RAPIDLY WITHIN
THESE STORMS.

THE MAIN SLUG OF MOISTURE THAT HAS PLAGUED RDG AND ABE MOST OF THE DAY
APPEARS TO BE WEAKENING AS IT VERY SLOWLY MAKES ITS WAY TO THE
SOUTHEAST. NOT EXPECTING MUCH OF THIS MOISTURE TO MAKE IT ALL THE
WAY TO PHL AND INTO NEW JERSEY HOWEVER THERE COULD STILL BE SOME
SCATTERED SHOWERS AFTER 21Z ACROSS THE METRO AREA. AFTERWARD, WITH
THE LOW OFFSHORE, WINDS WILL SWING MORE TO THE NORTH-NORTHWEST
ACROSS THE ENTIRE REGION AND A GRADUAL DRYING TREND WILL TAKE PLACE.
STILL EXPECTING THE CIGS TO REMAIN IN THE MVFR RANGE THROUGH THE
REMAINDER OF THE EVENING, HOWEVER, WITH A VERY SATURATED GROUND AND
A COOL AIRMASS MOVING IN TONIGHT, AREAS OF BR AND POSSIBLY FOG MAY
FORM. MAY HAVE SOME ISSUES WITH IFR CIGS OVERNIGHT TONIGHT, BUT IT
SHOULD REMAIN FAIRLY ISOLATED.

BY LATE TOMORROW MORNING WE SHOULD BE SEEING THE BR AND LOWER
MVFR/IFR STARTING TO BURN OFF. STILL ARE NOT EXPECTING TO GET BACK
TO VFR CONDITIONS UNTIL THURSDAY AFTERNOON AS THE SURFACE LOW
PRESSURE MOVES FURTHER OFFSHORE AND WE LOSE IT INFLUENCE COMPLETELY
ACROSS THE REGION.

OUTLOOK...
VFR CONDITIONS SHOULD BEGIN TO PREVAIL BY THURSDAY AFTERNOON AS
CENTER OF LOW PRESSURE MOVES FURTHER OFFSHORE AND WE LOSE ANY
REMAINING LOW LEVEL MOISTURE. NEXT FRONTAL SYSTEM LOOKS TO ENTER IN
FROM THE WEST BY LATE FRIDAY EVENING SPILLING INTO SATURDAY. A
CHANCE OF SHOWERS AND THUNDERSTORMS WILL PERSIST THROUGH THE
OVERNIGHT FRIDAY HOURS. VFR CONDITIONS SHOULD REMAIN IN PLACE
THROUGH A BETTER PART OF THE WEEKEND WITH POSSIBLY OF MORE
ORGANIZED THUNDERSTORMS ON SATURDAY WITH THE ACTUAL COLD FRONT
PASSAGE.

&&

.MARINE...
LOW PRESSURE CENTERED OVER THE SOUTHERN NEW JERSEY AREA WILL
CONTINUE TO MOVE OFFSHORE THROUGH THE EVENING AND OVERNIGHT
HOURS...VERY SLOWLY. A WEAKENING SOUTHERLY FLOW OVER THE WATERS WILL
TURN GRADUALLY MORE NORTHERLY AS THE LOW PUSHES FURTHER OUT TO SEA
TONIGHT. THE CURRENT SMALL CRAFT ADVISORY FOR HIGHER SEAS WILL BE
LEFT IN PLACE THROUGH 00Z TONIGHT. BUOY 44009 HAS SEEN A DOWNWARD
TREND THROUGH THE DAY, IT MAXED OUT AT CLOSER TO 7 FEET THIS
MORNING. THE REMAINDER OF THE OUR WATERS WILL BE EXPERIENCING THIS
TREND AS WELL TONIGHT.

THE SEAS WILL RETURN MORE TRANQUIL ON THURSDAY WITH A NORTHWESTERLY
FLOW. WE DO NOT LOSE ALL OF THE LOWER LEVEL MOISTURE UNTIL LATE ON
THURSDAY MEANING WE COULD SEE A FEW PASSING SHOWERS AND
THUNDERSTORMS. THE NEXT SYSTEM WE ARE CURRENTLY WATCHING FOR DOES
NOT MOVE INTO THE REGION UNTIL LATE FRIDAY NIGHT INTO SATURDAY
MORNING. THIS AGAIN MAY PRODUCE SCATTERED SHOWERS AND THUNDERSTORMS
ON FRIDAY AND SATURDAY. AHEAD OF THE ACTUAL FRONTAL PASSAGE WE MAY
SEE SEAS AND WINDS BUILD CLOSE TO SCA CRITERIA, BUT BEING THIS FAR
FROM THE TIME PERIOD, IT IS NOT BEING FORECASTED.

&&

.HYDROLOGY...
A FEW STRONG AND SLOW MOVING THUNDERSTORMS OVER THE AREA CONTINUE
TO PRODUCE HEAVY DOWNPOURS AND FLOODING. SOME RADAR ESTIMATED ONE
HOUR AMOUNTS OF UP TO TWO INCHES HAVE BEEN REPORTED.
