AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MOUNT HOLLY NJ
803 PM EDT TUE JUN 28 2011

.SYNOPSIS...
A WARM FRONT ACROSS SOUTHERN NEW JERSEY WILL EDGE NORTH THIS
EVENING. A COLD FRONT WILL MOVE EAST THROUGH THE MID ATLANTIC
STATES TONIGHT. THEN AN AREA OF HIGH PRESSURE OVER THE GREAT LAKES
ON WEDNESDAY WILL MOVE TO THE MID ATLANTIC STATES BY FRIDAY AND
OFFSHORE ON THE WEEKEND. A SERIES OF WEAKENING COLD FRONTS ARE
THEN EXPECTED TO PASS INTO OR THROUGH THE REGION SUNDAY THROUGH
TUESDAY.

&&

.NEAR TERM /UNTIL 6 AM WEDNESDAY MORNING/...
TO THIS POINT...THE MAIN CONVECTIVE AREAS HAVE BEEN TO THE NORTH
ACROSS NEW YORK STATE AND NEARBY PENNSYLVANIA (WHERE THE BETTER
SHEAR IS) AND ACROSS VIRGINA (WHERE THE BEST INSTABILITY LIES). IN
BETWEEN...WIDELY SCATTERED STORMS HAVE HAD A HARD TIME MAINTAINING
STRONG UPDRAFTS DESPITE RELATIVELY UNCAPPED CONDITIONS AS WELL AS
DECENT INSTABILITY. IT APPEARS AS THOUGH THE WEAKENING STATIONARY
FRONT IS NOT PROVIDING SUFFICIENT FOCUS FOR THE STORMS TO BECOME
BETTER ORGANIZED.

THE SHORT WAVE OVER EASTERN ONTARIO WILL DRIVE THE CONVECTION
ACROSS THE NORTH THIS EVENING. THE LATEST HRRR SUGGESTS THAT THE
ACTIVITY DANGLING DOWN INTO CENTRAL PENNSYLVANIA WILL BECOME THE
MAIN AREA OF CONVECTION THAT AFFECTS THE FORECAST AREA. SO...THE
FORECAST WILL CONTINUE TO SHOW THE BEST CHANCE OF SHOWERS AND
THUNDERSTORMS ON THE EDGE...WITH THE BEST SHEAR NORTH AND THE BEST
INSTABILITY SOUTH.

THE ENHANCED WORDING WAS RETAINED FOR MUCH OF THE AREA AS WELL...
WITH THE BEST CHANCE OF GUSTY WINDS ACROSS NORTHERN AREAS (AS WELL
AS SMALL HAIL). THE STORMS ACROSS THE SOUTH HAVE ACCESS TO
PRECIPITABLE WATER VALUES NEAR 1.90 INCHES...AND NORTHEAST
MARYLAND AND DELAWARE COULD SEE LOCALLY HEAVY RAIN. IN THESE
AREAS...FLASH FLOOD GUIDANCE NUMBERS ARE HIGH...SO NO MORE THAN
NUISANCE FLOODING IS EXPECTED.

THE COLD FRONT SHOULD CROSS THE REGION BETWEEN 0500 UTC AND 0900
UTC...WEST TO EAST. WITH THE PASSAGE OF THE FRONT...THERE COULD BE
A BRIEF PERIOD OF GUSTY WINDS (AS IT OCCURRING NOW OVER OHIO)...
BUT THIS MAY NOT LAST. IN FACT...SHELTERED LOCATIONS MAY ACTUALLY
SEE PATCHY FOG DEVELOP BEFORE DAYBREAK. FOR THE MOST PART...LOWS
WERE NOT CHANGED...AS THE LATE ARRIVING FRONT WILL NOT HAVE ENOUGH
TIME FOR AN AIRMASS CHANGE TO BE DELIVERED TONIGHT.

&&

.SHORT TERM /6 AM WEDNESDAY MORNING THROUGH FRIDAY/...
ASIDE FOR THE POSSIBILITY OF SOME LEFTOVER SHOWERS EARLY SOUTHEAST,
THE REST OF THE SHORT TERM WILL BE DRY WITH A PLEASANT END TO JUNE
AND START TO JULY BEFORE HOTTER WEATHER RETURNS.

NOT MUCH CHANGE TO MODELING FOR WEDNESDAY DAY AS THERE WILL BE A
CYCLONIC FLOW ALOFT, BUT NOT TOO MANY SHORT WAVES OF CONSEQUENCE. IN
ACTUALITY IF THE GFS TIMING IS NOT WAY TOO FAST, THERE WILL BE
LESS PVA IN THE AFTN THAN MORNING. REGARDLESS THE CAPPING IS
FORECAST TO BE IN PLACE BY AFTN WITH BOTH THE GFS AND WRF-NMM FCST
SOUNDINGS THROUGHOUT OUR CWA. SO WHILE SOME CU MIGHT FORM,
ESPECIALLY NORTH, NO PCPN IS FORECAST. BECAUSE OF THE WARM START
AND DOWNSLOPING WINDS, WE DID GO SLIGHTLY ABOVE STAT GUIDANCE FOR
MAX TEMPS. THERE SHOULD BE SOME RELATIVE BRISKNESS TO THE WINDS
AND PEAK GUSTS SHOULD REACH INTO THE 20S.

THEN FOR BOTH WEDNESDAY AND (JUMPING TO) THURSDAY NIGHTS, LOOKS LIKE
PLEASANT SLEEPING WEATHER WITH DEW POINTS WE MIGHT NOT SEE AGAIN
UNTIL SEPTEMBER. WE WENT SLIGHTLY BELOW STAT GUIDANCE IN OUTLYING
AREAS AS SKIES SHOULD BE MAINLY CLEAR AND WINDS SHOULD DECOUPLE,
ESPECIALLY THURSDAY NIGHT.

THURSDAY DAY LOOKS CLOSE TO A REPEAT OF WEDNESDAY EXCEPT WITH
SLIGHTLY LESS WINDS AND CLOUDS AS THE CLOSED LOW TO OUR NORTH WILL BE
OPENING AND MOVING TOWARD THE CANADIAN MARITIMES. WHILE THE FLOW
ALOFT WILL REMAIN CYCLONIC, ANY APPRECIABLE SHORT WAVES ARE STILL
FORECAST TO BE TO OUR WEST. STAT GUIDANCE LOOKS A SMIDGE TOO LOW FOR
MAX TEMPS BASED ON FCST 1000-850MB THICKNESSES. ANOTHER RELATIVELY
DRIER BUT WARMER DAY EXPECTED ON FRIDAY. THE GFS FAST BIAS FROM THE
GET GO IS LIKELY IN PLACE ON THIS DAY (LATEST ECMWF 2C COOLER AT
850MB). THIS IS ONE CASE WHERE WE WERE A BIT CONSERVATIVE WITH MAX
TEMPS VS MEX MOS. ANY RETURN FLOW CONVECTION OR DEBRIS AS OF NOW
LOOKS TO REMAIN MAINLY WEST OF OUR CWA THRU FRIDAY AFTN.

&&

.LONG TERM /FRIDAY NIGHT THROUGH TUESDAY/...
THE POTENTIAL FOR A HEAT WAVE OUTSIDE OF THE TERRAIN AND AWAY FROM
THE WATER IS INCREASING FOR SATURDAY INTO TUESDAY. OCCASIONAL
WEAK COLD FRONTAL PASSAGE BRINGING THE CHANCE FOR SHOWERS AND
THUNDERSTORMS IN THE SUNDAY THROUGH TUESDAY TIMEFRAME. HOWEVER...
TIMING AND PLACEMENT OF THE CONVECTION WILL PROBLEMATIC AS SHORT
WAVES ERODE THE MID LEVEL RIDGE FROM THE TOP DOWN.

SURFACE HIGH PRESSURE WILL CREST OVER THE MID ATLANTIC STATES FRIDAY
NIGHT...AS MID LEVEL RIDGING STARTS TO BUILD NORTHEAST. THE MID
LEVEL RIDGE CRESTS OVER THE MID ATLANTIC SATURDAY AFTERNOON. 850 MB
TEMPERATURES NEAR 16 CELSIUS SUGGEST THAT HIGHS AROUND 90 ARE
POSSIBLE AWAY FROM THE COAST AND OUTSIDE OF THE TERRAIN FOR SATURDAY.

THE MID LEVEL RIDGING SHOULD KEEP THE COLUMN CAPPED THROUGH SATURDAY
EVENING. THEREFORE...THE TIME PERIOD FRIDAY NIGHT INTO SATURDAY
EVENING WAS KEPT MOSTLY DRY. THE EXCEPTION COULD BE THE SOUTHERN
POCONOS AND NORTHWEST NEW JERSEY...WHERE THE BEST INSTABILITY AND
WEAKEST PORTION OF THE CAP LOOK TO BE.

THE MID LEVEL RIDGING STARTS TO BUCKLE AS A SHORT WAVE TRIES TO TOP
IT SUNDAY INTO SUNDAY EVENING. THE SHORT WAVE WILL PUSH A WEAK COLD
FRONT TOWARD THE REGION DURING THE AFTERNOON AND EVENING. AGAIN...
WARM MID LEVEL TEMPERATURES SHOULD RESULT IN CAPPING FOR MOST
LOCATIONS...WITH THE HIGH TERRAIN AGAIN BEING THE MOST LIKELY PLACE
TO SEE THE CAP BROKEN. 850 MB TEMPERATURES REACHING NEAR 19 CELSIUS
SHOULD RESULT IN HIGHS IN THE LOWER TO MID 90S...WHICH IS CLOSE TO
THE MID RANGE GUIDANCE.

ANY SUNDAY EVENING CONVECTION SHOULD DISSIPATE SUNDAY EVENING. AFTER
THIS...THE TIMING OF INDIVIDUAL SHORT WAVES RIDING OVER THE MID
LEVEL RIDGE WILL BECOME INCREASINGLY PROBLEMATIC. WITH THIS IN
MIND...SHOWERS AND THUNDERSTORMS WERE INSERTED INTO THE FORECAST FOR
MONDAY AND TUESDAY AFTERNOON...MAINLY ACROSS NORTHERN AND WESTERN
AREAS. TIMING AND PLACEMENT OF THUNDERSTORMS FOR THE SUNDAY NIGHT
INTO TUESDAY EVENING TIMEFRAME WILL HAVE TO BE RESOLVED AS THESE
DAYS DRAW CLOSER.

MONDAY COULD END UP BEING THE HOTTEST DAY OF THE MID RANGE
PERIOD...AS 850 MB TEMPERATURES REACH NEAR 20 CELSIUS. THIS COULD
EQUATE TO MID 90S FOR MOST PLACES OUTSIDE OF THE TERRAIN AND AWAY
FROM THE WATER. HIGHS MAY BE SLIGHTLY COOLER TUESDAY WITH MID LEVEL
HEIGHTS FALLING AND 850 MB TEMPERATURES DROPPING BACK A COUPLE OF
DEGREES.

&&

.AVIATION /00Z WEDNESDAY THROUGH SUNDAY/...
THE FOLLOWING DISCUSSION IS FOR KPHL, KPNE, KTTN, KABE, KRDG, KILG,
KMIV, KACY AND SURROUNDING AREAS.

WIDELY SCATTERED SHOWERS AND THUNDERSTORMS SHOULD BECOME BETTER
ORGANIZED AS A COLD FRONT APPROACHES FROM THE WEST. THE AIRMASS
AHEAD OF IT REMAINS MODERATELY UNSTABLE...AND THUNDERSTORMS MAY TROT
FORM ALONG THE LEE SIDE TROUGH. THE LATEST HRRR SUGGESTS THAT THE
SCATTERED LINE EXTENDING FROM KELM TO NEAR KUNV WILL TRY TO CONGEAL
AND AFFECT NORTHERN SECTIONS OF THE AREA BETWEEN 0200 UTC AND 0500
UTC.

WITH THE 0000 UTC ISSUANCE...MOST TERMINALS WILL INCLUDE A CB REMARK
TO SUGGEST THE CONVECTIVE THREAT...AND TSRA WILL BE ADDED TO THE
TERMINALS VIA AMENDMENTS AS THE THREAT GROWS.

OTHERWISE...THE WEAK STATIONARY FRONT STRETCHING ACROSS SOUTHEAST
PENNSYLVANIA AND SOUTHWEST NEW JERSEY INTO DELAWARE SHOULD BEGIN TO
DISSIPATE IN THE LOW LEVEL FORCING AHEAD OF THE COLD FRONT. ALL
TERMINALS ARE NOW VFR AHEAD OF THE COLD FRONT...AND ARE EXPECTED TO
REMAIN THAT WAY THROUGH THE FRONTAL PASSAGE.

THE COLD FRONT SHOULD CROSS KRDG BEFORE 0500 UTC...AND PASSE KACY
AFTER 0900 UTC. AS THE FRONT CROSSES...THE CONVECTIVE ELEMENTS
SHOULD BE WIDESPREAD NORTH AND SCATTERED SHOWER. ANY THUNDERSTORM
COULD PRODUCE A GUST TO 30 KNOTS...AS WELL AS MVFR CONDITIONS FOR
CEILINGS AND VISIBILITIES.

AFTER THE FRONTAL PASSAGE...THE WEST NORTHWEST GRADIENT SHOULD
INCREASE. HOWEVER...IT MAY NOT INCREASE FAST ENOUGH TO PRECLUDE MVFR
FOG AT BOTH KRDG AND KMIV BETWEEN 0800 UTC AND 1200 UTC. THE COLUMN
DRIES QUICKLY WEDNESDAY. MODEL SOUNDINGS SUGGEST GUSTS BETWEEN 19 AND
24 KNOTS BETWEEN 16000 UTC AND 2100 UTC WEDNESDAY FOR ALL TERMINALS.

THE DRIER COLUMN SHOULD MEAN CLEAR SKIES THROUGH THE MORNING. AS
CONVECTIVE TEMPERATURES ARE REACHED IN THE EARLY AFTERNOON...CUMULUS
WILL DEVELOP. RIGHT NOW...IT APPEAR AS THOUGH THE CUMULUS WILL
REMAIN SCATTERED.

OUTLOOK...
MOSTLY VFR CONDITIONS ARE FORECAST FOR WEDNESDAY NIGHT THROUGH
FRIDAY...AS HIGH PRESSURE WILL BUILD OVER OUR AREA THURSDAY AND
FRIDAY. A COASTAL TROUGH MAY SET UP ALONG THE COAST OVER THE
WEEKEND...WITH PERHAPS SOMEWHAT MORE UNSETTLED CONDITIONS.

&&

.MARINE...
MARINE CONDITIONS ARE FORECAST TO REMAIN BELOW SMALL CRAFT ADVISORY
CONDITIONS THROUGH THIS WEEK...AND PERHAPS INTO OR EVEN THROUGH THE
COMING WEEKEND AS WELL.

SOME SHOWERS WERE BEING GENERATED BY A WARM FRONT IN OUR AREA AT
EARLY AFTERNOON...UNDER THE INFLUENCE OF A PRE-COLD FRONTAL
SOUTHEAST TO SOUTH FLOW. THE ASSOCIATED COLD FRONT WILL APPROACH
FROM THE WEST AND MOVE THROUGH THE COASTAL WATERS OVERNIGHT.
SCATTERED TO PERHAPS BROKEN SHOWERS AND THUNDERSTORMS WILL OCCUR
WITH THE COLD FRONT. WINDS SHOULD GENERALLY BE UNDER 20 KNOTS AHEAD
OF THE COLD FRONT.

BEHIND THE COLD FRONT...WINDS WILL BECOME WEST TO NORTHWEST AT 10 TO
15 KNOTS OVERNIGHT INTO WEDNESDAY MORNING...THEN GUST OCCASIONALLY
TO 20 KNOTS DURING WEDNESDAY IN THE OFFSHORE FLOW. THIS SHOULD NOT
HAVE MUCH IMPACT ON SEAS...WHICH ARE FORECAST NO HIGHER THAN 4 FEET
TONIGHT AND WEDNESDAY.

HIGH PRESSURE WILL BUILD OVER THE AREA WATERS THURSDAY AND FRIDAY. A
COASTAL TROUGH MAY SET UP ALONG THE COAST OVER THE WEEKEND...WITH
PERHAPS SOMEWHAT MORE UNSETTLED CONDITIONS.

&&

.CLIMATE...
KPHL IS PROJECTING A JUNE AVG AROUND 75.4 OR TOP 10 WARMEST...BUT
WELL BELOW LAST YEARS XMACIS RESOURCED 78.2 AVG FOR JUNE.
XMACIS PERIOD OF RECORD /POR/ BEGINS 1873.

KACY IS PROJECTING A JUNE AVG TEMP OF ABOUT 74.4 OR TOP 5 WARMEST
JUNE BUT BELOW LAST YEARS 75.8 DEG XMACIS RESOURCED AVG FOR JUNE.
XMACIS POR BEGINS 1874.

KILG IS PROJECTING A JUNE AVG TEMP OF ABOUT 74.0...LAST YEAR IT
