AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MOUNT HOLLY NJ
313 PM EDT MON MAY 31 2010

.SYNOPSIS...
A BLOCKY WEATHER PATTERN IS GOING TO BE REPLACED BY A MORE
PROGRESSIVE ONE OVER THE NEXT WEEK. THE FORECAST AREA WILL BE NEAR
THE SOUTHERN PERIPHERY OF THE WESTERLY FLOW ALOFT INTO SATURDAY AND
AS SUCH A FEW FRONTAL BOUNDARIES WILL REACH, QUICKLY STALL AND THEN
MOVE BACK TO THE NORTH. COLD FRONTS SHOULD MOVE INTO THE REGION ON
TUESDAY AND FRIDAY BEFORE THEY STALL AND MOVE BACK TO THE NORTH.
A STRONGER COLD FRONTAL PASSAGE IS THEN FORECAST FOR SUNDAY NIGHT.

&&

.NEAR TERM /UNTIL 6 AM TUESDAY MORNING/...
THE GFS INITIALIZED SLIGHTLY BETTER THAN THE WRF-NMM WITH THE 12Z
SOUNDINGS. IN TERMS OF 6HR VERIFICATION, ALL OF THE NOAM MODELS ARE
NOT WIDESPREAD ENOUGH WITH THE CONVECTION ASSOCIATED WITH THE OPENING
CLOSED LOW OVER THE SERN CONUS AND THE MESOSCALE WRF MDLS HAVE
BEEN HIT AND MISS WITH THE CONVECTION OVER THE OHIO VALLEY AND
CENTRAL APPALACHIANS. BECAUSE THE IAD SOUNDING WAS WETTER THAN THE
MODELS INITIALIZED, WE ARE CONTINUING THE TREND OF INCREASING POPS
FOR THIS EVENING AND WILL BE FOLLOWING THE GFS SHORT WAVES AND
NORTHERN AXIS OF THE FCST LLJ FOR DELINEATING POPS. THE SEA BREEZE
FRONT CONTINUES TO MAKE PROGRESS INTO NJ, MOST OF THE OBSERVED
CAPES IN THE CENTRAL AND SOUTHERN PART OF THE STATE ARE LESS THAN
2000J, SO THE PLACE WHERE IT MIGHT TRIGGER SHRAS OR TSRAS SHOULD
BE IN THE SWRN PART OF THE STATE INTO EARLY THIS EVE.

FORECAST BULK SHEAR VALUES REMAIN RATHER TAME FOR THIS AFTERNOON AND
IN TERMS OF GUSTY WINDS OR SEVERE POTENTIAL. THE BEST THING GOING IF
ONE WANTS TO CALL IT THAT IS THE INVERTED V FORECAST SOUNDINGS. AS
SUCH THE LATEST SREF OUTPUT STILL PLACES SERN PA AS THE BEST CHANCE
FOR STRONGER/SEVERE STORMS IN OUR CWA THRU ABT 00Z THIS EVE.
AFTER THAT THE POTENTIAL TURNS MORE TOWARD HEAVY RAIN PRODUCING
TSRAS VS WIND. WE BELIEVE OUR CWA WILL NOT BE ON THE SAME PAGE
WITH FORCING MECHANISMS. WHILE THEY SHOULD MAINTAIN THUNDER INTO
THE EVE AND PROBABLY INTO THE NIGHT, THEY ARE NOT COINCIDENTAL. A
LLJ IS FORECAST TO DEVELOP AND MOVE ACROSS THE SERN PART OF OUR
CWA OVERNIGHT, BUT THE GREATEST FCST THETA E AND WAA IS SUPPOSE TO
OCCUR THIS EVE. ALSO THE FCST SHORT WAVE ENHANCING THE CONVECTION
SHOULD BE IN THE CATSKILLS BY THEN. OUTSIDE OF THE MANATAWNY
BASIN IN BERKS/MONTGOMERY COUNTY, MOST OF THE FFG FOR OUR CWA IS
RATHER HIGH, SO NO WATCH IS PLANNED ATTM. WE WILL CARRY ENHANCED
STRONG WIND WORDING IN THE GRIDS THRU 7 PM AND THEN ENHANCED HEAVY
RAIN WORDING FOR THE NW HALF OF OUR CWA UNTIL THE SHORT WAVE
CLEARS.

CAN NOT SEE MINS DROPPING MUCH WITH HIER DEWPTS ADVECTING IN ALOFT
AND CLOUDS AND A BIT OF SW WIND PREVAILING. STAT GUIDANCE SEEMS TO
BE ON TO THIS AND WAS PRETTY MUCH FOLLOWED. A STICKY NIGHT FOR OUR
CWA.

&&

.SHORT TERM /6 AM TUESDAY MORNING THROUGH THURSDAY/...
MORE OF THE FORCING MECHANISMS NOT BEING ON THE SAME PAGE ON
TUESDAY. THE LLJ IS FORECAST TO EXIT DURING THE MORNING. THERE IS
NEUTRAL LLVL WAA FORECAST. THE ENTRANCE REGION OF THE H2.5 JET AND
THE BEST FCST BULK SHEAR IS IN THE NW PART OF OUR CWA LATE IN THE
DAY, POSSIBLY TOO LATE. SREF GUIDANCE SUGGESTING BECAUSE OF THE
FORCING ALOFT (A SHORT WAVE INVOLVED TOO) THAT THIS SHOULD BE THE
BEST CHANCE FOR STG/SEVERE STORMS ALTHOUGH ONCE AGAIN THE CHANCES
ARE RELATIVELY LOW ESPECIALLY WHEN COMPARED TO THE IOWA AREA. WE
ALSO WILL HAVE ALL THE DEBRIS TO CLEAR AND NOT MUCH OF A CAP OR
FCST CIN, THUS HAVE WEAKER SHRAS OR TSRAS START BEFORE THE FRONT
ARRIVES. FCST MID LVL LAPSE RATES REMAIN SO-SO AND THE SKINNY
LOOKING FCST CAPE DOES NOT APPEAR FOREBODING. TOO MANY IFS AT THIS
POINT TO CARRY ENHANCED WORDING. WOULD LIKE TO GIVE THE MID SHIFT
THE CHANCE TO SEE HOW ALL OF THE CONVECTION OVER THE SERN CWA
MUDDIES THE CONVECTIVE POTENTIAL FOR TUESDAY. STILL GIVEN THE
LONG DAY WOULD BE PRUDENT TO CONTINUE THE TREND OF GOING ABOVE
STAT GUIDANCE FOR MAX TEMPS AS PREV SHIFT NOTED NOT TOO MANY
CLOUDY JUNE DAYS AND IT WON'T TAKE MUCH JUNE SUN TO GET TO OUR
FCST HIGH TEMPS. ITS GOING TO BE MORE DIFFICULT FOR THE SEA BREEZE
TO MAKE AN INLAND ADVANCE ON TUESDAY THAN TODAY AS THE FORECAST
WINDS ABOVE THE BOUNDARY LAYER WILL BE STRONGER FROM THE SW VS
PRETTY MUCH LIGHT AND VARIABLE TODAY.

SREF GUIDANCE SUGGESTING A SHARPER CDFNTL PASSAGE THAN EITHER OF OUR
OPERATIONAL MODELS WHICH LOOKS OK GIVEN WE ARE FCST TO BE IN THE
WESTERLIES AT 500MB. WE MADE NO CHANGE TO THE PROGRESSION OF PCPN
TUE NGT. KEPT WED PCPN FREE AS THE FCST MOISTURE SHOULD BE A
LIMITING FACTOR. FCST 850MB TEMPS AND 1000-850 TEMPS SUPPORT STAT
GUIDANCE.

WEDNESDAY NIGHT AND THURSDAY ARE MIRRORING SUNDAY NIGHT AND TODAY TO
A CERTAIN EXTENT WITH DECENT WAA FORECAST DURING THE DAY ON
THURSDAY. THE GENERAL MODEL TREND HAS BEEN FOR A SLIGHTLY FASTER CFP
OVER THE LAST COUPLE OF DAYS. THIS SEEMS LOGICAL GIVEN THAT THE
FORECAST FLOW IS PROGRESSIVE. SO WE DID INCREASE THE POPS AND
EXTENDED THEM FARTHER TO THE SOUTH WI OUR CWA FOR THE DAY ON
THURSDAY. THURSDAY SHOULD HAVE SIMILAR TEMPERATURE AND DEW POINT
LEVELS AS TODAY. THE GFS IS WARMER THAN THE WRF-NMM BY THIS
FORECAST JUNCTURE, BUT GIVEN HOW LITTLE COOLING WE ARE EXPECTING
CENTERED AROUND WEDNESDAY, THE MEX MOS MAX TEMPS APPEAR
REASONABLE.

&&

.LONG TERM /THURSDAY NIGHT THROUGH SUNDAY/...
A FRONTAL BOUNDARY FROM THE NORTHWEST IS EXPECTED TO DROP INTO OUR
REGION ON THURSDAY NIGHT AND FRIDAY. WITH THE UPPER PATTERN FORECAST
TO BECOME ZONAL FOR THE LATE PART OF THE WEEK INTO SATURDAY, THE
FRONT SHOULD NOT HAVE MUCH OF A PUSH BEHIND IT. AS A RESULT, WE ARE
EXPECTING THE BOUNDARY TO EITHER STALL OR DISSIPATE OVER OUR REGION.
IN EITHER CASE, WE WILL INTRODUCE CHANCE POPS TO OUR NORTHERN
COUNTIES ON THURSDAY NIGHT AND CARRY CHANCE POPS EVERYWHERE FOR
FRIDAY. WE WILL LINGER CHANCE POPS INTO FRIDAY EVENING, MAINLY IN
OUR SOUTHERN COUNTIES.

ISOLATED CONVECTION IS POSSIBLE ON SATURDAY WITH THE REMNANTS OF THE
FRONTAL BOUNDARY NEARBY, SO WE WILL CARRY SLIGHT CHANCE POPS.

A SHORT WAVE IS EXPECTED TO PASS OVER THE GREAT LAKES REGION ON
SUNDAY. THE FEATURE IS THEN FORECAST TO PASS ACROSS THE NORTHEASTERN
STATES IN THE SUNDAY NIGHT INTO MONDAY TIME FRAME. THE SHORT WAVE
MAY PROVIDE ENOUGH OF A PUSH TO CAUSE A COLD FRONT FROM THE
NORTHWEST TO MAKE ITS WAY THROUGH OUR REGION. WE WILL INCLUDE CHANCE
POPS FOR SHOWERS AND THUNDERSTORMS FOR SUNDAY AFTERNOON INTO SUNDAY
NIGHT, OUT AHEAD OF THE COLD FRONT.

IF THE COLD FRONT CLEARS OUR REGION, WE WILL SEE DRY WEATHER
CONDITIONS FOR MONDAY.

IT LOOKS AS THOUGH MAXIMUM TEMPERATURES WILL BE MAINLY IN THE 80S
FOR FRIDAY, SATURDAY AND SUNDAY, WITH OVERNIGHT LOWS IN THE 60S AND
LOWER 70S. IT MAY BE A BIT COOLER FOR MONDAY.

&&

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

VFR CONDS ARE GENLY EXPECTED THROUGH THE NIGHT WITH A COMBINATION OF
HIGH CLOUDS AND CU OVER MOST LOCATIONS.  HOWEVER, LATEST RADAR
IMAGERY SHOWED SOME ISOLATED TSTMS OVER THE REGION.  WHILE THE
CHANCES OF THEM HITTING ANY PARTICULAR AIRPORT ARE LOW, IT CAN NOT
BE RULED OUT.  SINCE AREAL COVERAGE AND CONFIDENCE ARE LOW, WILL
HANDLE THIS SCENARIO WITH AMENDMENTS.

AFTER SUNSET, AREAL COVERAGE OF ANY STORMS SHOULD DECREASE.  SWLY
WINDS WILL REMAIN AROUND 10 KTS DURG THE DAY AND DROP A0B 10 KTS
OVERNIGHT.  WINDS WILL BECOME MORE WSW ON TUESDAY AND INCREASE AS
HIGH AS 15 KTS DURG THE DAY.  THERE IS A BETTER CHC OF MORE
WIDESPREAD TSTMS ON TUESDAY AS A CDFNT APPROACHES THE REGION.
HOWEVER, THERE IS STILL SOME UNCERTAINTY AS TO EXACT TIMING AND AREAL
COVERAGE.  OBVIOUSLY, ANY TSTMS COULD BRING MVFR AND IFR CONDS, AND
HAVE STARTED TO MENTION THEM IN THE TAF PKG.

OUTLOOK...
HIGH PRESSURE WILL BRING A RETURN TO FAIR WEATHER WITH GOOD FLYING
CONDITIONS WEDNESDAY INTO THURSDAY BEFORE ANOTHER, AND STRONGER,
FRONT MOVES IN LATE IN THE WEEK.

&&

.MARINE...
TRANQUIL CONDS REMAIN IN PLACE OVER THE AREA WATERS ON THIS LAST DAY
OF THE HOLIDAY WEEKEND.  WINDS ARE LIGHT AND SEAS ARE GENLY AROUND 2
FT.  EXPECT THE QUIET WX TO REMAIN OUTSIDE OF ANY TSTMS.

WITH THE APPROACH OF THE AFOREMENTIONED CDFNT, WINDS AND SEAS WILL
INCREASE ON TUESDAY.  LATEST WAVEWATCH DATA INDICATES THAT SEAS MAY
HIT 5 FT TUESDAY AFTN.  HOWEVER, OTHER MDL GUIDANCE KEEPS WINDS
BELOW CRITERIA, SO ITS PSBL THE SEAS ARE OVERDONE.  NOT A LOT OF
CONFIDENCE ON HOW THIS WILL ALL PLAY OUT, SO FOR NOW WILL REFRAIN
FROM ISSUING ANY FLAGS. THE CDFNT WILL ALSO BRING MORE WIDESPREAD
SHOWERS AND TSTMS WHICH COULD INCREASE WINDS AND SEAS AS WELL.

HIGH PRESSURE WILL RETURN WEDNESDAY INTO THURSDAY, BEFORE ANOTHER
CDFNT APPROACHES THURSDAY NIGHT OR FRIDAY.  ADDITIONAL MARINE FLAGS
MAY BE NEEDED AT THAT POINT.
