AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MOUNT HOLLY NJ
528 AM EDT THU AUG 12 2010

.SYNOPSIS...
HIGH PRESSURE BUILDS INTO COASTAL NORTHERN NEW ENGLAND THROUGH FRIDAY
AND FILTERS COOLER AIR INTO OUR AREA. MEANWHILE...LOW PRESSURE
ORGANIZING ALONG THE NORTH CAROLINA COAST TODAY WILL PRODUCE SHOWERS...
SOME HEAVY...TO PARTS OF OUR AREA TODAY...ESPECIALLY THE INTERIOR.
THE LOW WILL MOVE OUT TO SEA FRIDAY. BY THE END OF THE WEEKEND THE
NEW ENGLAND HIGH PRES SYSTEM WILL STRETCH FROM THE MARITIMES TO
THE CAROLINA COAST AND RETURN VERY WARM AND HUMID AIR TO OUR AREA
NEXT WEEK. A COOL FRONT WILL APPROACH FROM THE WEST NEXT TUESDAY
OR WEDNESDAY.

&&

.NEAR TERM /UNTIL 6 PM THIS EVENING/...
ISOLATED HEAVY SHOWERS IN NW NJ AND NE PA THROUGH 515 AM. NOWS
ISSUED. SO FAR FFMP KEEPS THIS UNDER 1.75 INCHES AND NOR PROBLEMS
BUT NEEDS TO BE MONITORED FOR SLOW MOVING UNDER 20K TOP SHOWERS.

LARGE MASS OF SHOWERS ASSTD WITH MID LEVEL VT MAX WILL PROBABLY
TURN ESEWD TODAY. TIMES INTO PHL 12Z-13Z IF IT HOLDS TOGETHER.

THUNDER SHOULD BE CONFINED TO THE FAR W PART OF OUR AREA TODAY.

POP FORECAST IS AVERAGE OR BELOW AVERAGE WITH THE EXTENT OF
WIDESPREAD MEASURABLE SOMEWHAT IN DOUBT THOUGH IT LOOKS LIKE SE
PA...NE MD...DEL ARE TARGETED TODAY.

MAX TEMPS TODAY WILL BE AFFECTED BY THE TIMING OF THE SHOWERS WITH
THE MIDDAY/AFTN MAX TEMP. HAVE FCST BELOW THE COMBINED NCEP MOS
GUIDANCE IN INTERIOR S NJ ...DEL/SE PA AND MAY STILL BE TOO WARM
THIS AFTN?

&&

.SHORT TERM /6 PM THIS EVENING THROUGH SATURDAY NIGHT/...
INCREASING E BL FLOW AND SE FLOW JUST ABOVE THE BL EXPECTED INTO
FRI AS HIGH PRES BUILDS INTO COASTAL NEW ENGLAND.

HIGH PWAT AND SOMEWHAT UNSTABLE AIR IN THE FGEN REGEN WITH SELY
850 FLOW AND GENERALLY LIGHT AND EVENTUALLY EVOLVING NW FLOW AT 700
MB WILL PROBABLY YIELD SMALL POCKETS SUBSTANTIAL RFALL BY FRIDAY...
MAINLY DELAWARE RIVER/BAY WEST.

WHILE MOST SPOTS WILL PROBABLY SEE LESS THAN ONE HALF OF RAIN THE
NEXT DAY OR SO...BRIEF POOR DRAINAGE FLOODING PROBLEMS ARE NOT OUT
OF THE QUESTION IN THIS HIGH PWAT AIRMASS OF SLOW MOVING CELLS...
ESPECIALLY IF ANY OF THESE CELLS HOOK BECOME NEARLY STATIONARY FOR
MORE THAN AN HOUR.

THE POP FORECAST LOWERS FRIDAY AS DRIER AIR GRADUALLY INFILTRATES
TO THE WEST.

SATURDAY SHOULD SEE BRIGHTENING SKIES AS RIDGING ALOFT ARRIVES.

POPS WERE A BLEND OF 21Z SREF AND 00Z GFS MOS GUIDANCE.

BELOW AVG CONFIDENCE IN THE POP FCST TONIGHT AND FRIDAY. ITS
POSSIBLE THAT NO RAIN OCCURS AFTER TODAYS BATCHES OF SHOWERS
PROCEED SEWD OUT OF OUR AREA LATE TODAY.

TEMPS WERE BLENDED 00Z NAM/GFS MOS GUIDANCE AND MAY YET ADJUST A BIT
MORE ONCE THE DELAYED 00Z/12 ECMWF ARRIVES.

WE VIEWED THE SWODY1.

&&

.LONG TERM /SUNDAY THROUGH WEDNESDAY/...
THE OVERALL SYNOPTIC PATTERN IS COMPRISED OF AN EXPANSIVE
UPPER-LEVEL RIDGE ACROSS THE SOUTHERN STATES TO EVEN THE FOUR
CORNERS REGION. A RIDGE IS ALSO FORECAST TO BE POSITIONED IN FAR
WESTERN CANADA. THIS TYPICALLY POINTS TO TROUGHING MOVING ACROSS THE
REMAINDER OF CANADA WHICH THEN ALLOWS THE RIDGE TO AMPLIFY INTO THE
MID ATLANTIC AND NORTHEAST FOR A TIME. THE MODEL CONSENSUS OVERALL
IS GOOD REGARDING THIS PATTERN, HOWEVER AS ALWAYS THE CASE AS WE
FORECAST FARTHER OUT IN TIME, THE DETAILS BECOME NOT AS CLEAR. THIS
APPEARS TO REVOLVE AROUND THE TIMING OF ASSOCIATED COLD FRONTS INTO
THE NORTHEAST AS TROUGHING EVENTUALLY KNOCKS THE NARROW RIDGING DOWN
SOME, AND JUST HOW MUCH MOISTURE RETURN OCCURS ON THE BACKSIDE OF
THE DEPARTING SURFACE HIGH. THE MODEL GUIDANCE HAS BEEN TENDING TO
OVERDO THE CONVECTIVE CHCS/COVERAGE THIS SUMMER ACROSS THE BULK OF
OUR CWA. THIS MAY END UP BEING THE CASE AGAIN AS WE GO THROUGH THIS
TIME FRAME, ESPECIALLY IF THE UPPER-LEVEL ENERGY WITH THE INCOMING
TROUGH LAGS MORE TO OUR WEST. HPC WENT WITH THE GFS SOLUTION HOWEVER
SOME BLENDING OF THE GFS AND ECMWF WAS ALSO INCORPORATED. WE
INITIALIZED THE DATABASE WITH HPC GUIDANCE, BUT THEN MADE SOME
MOSTLY MINOR ADJUSTMENTS AFTER ADDITIONAL COLLABORATION. WE DID
LOWER HPC POPS SOME GIVEN INCREASED UNCERTAINTY IN TIMING AND
QUESTIONS REGARDING CONVECTIVE POTENTIAL/COVERAGE.

BASED ON THE ABOVE, HIGH PRESSURE NEAR THE COAST OF MAINE IS
FORECAST TO SLIDE EAST AND GIVE WAY ACROSS THE MID ATLANTIC. THIS IS
IN RESPONSE TO THE UPPER-LEVEL RIDGE BECOMING ERODED AS TROUGHING
AMPLIFIES INTO THE GREAT LAKES REGION. AS THE RETURN FLOW BECOMES
MORE ESTABLISHED ON THE BACKSIDE OF THE SURFACE HIGH, A WARM FRONT
SHOULD ORGANIZE AND LIFT NEAR THE AREA ESPECIALLY TO OUR WEST SUNDAY
AS THE STRONGER WAA IS FORECAST TO SURGE NORTHEASTWARD AHEAD OF A
COLD FRONT. THIS RETURN FLOW ALONG WITH THE WARM FRONT, MIGHT BE
ENOUGH TO PRODUCE SOME CONVECTION THEREFORE SOME SLIGHT CHC TO LOW
CHC POPS WERE USED FROM WEST TO EAST. SINCE THE MAIN TROUGH AXIS IS
FORECAST TO LINGER WELL TO OUR NORTHWEST FOR AWHILE, THE COLD FRONT
SHOULD TEND TO GRADUALLY SETTLE INTO OUR AREA MONDAY NIGHT AND
TUESDAY. SOME SHORT WAVE ENERGY SPINNING AROUND THE UPPER-LEVEL
TROUGH MAY BE ABLE TO FOCUS SOME CONVECTION, THEREFORE SLIGHT CHC TO
CHC POPS WERE USED THROUGH TUESDAY NIGHT. THE BETTER CHC MIGHT END
UP BEING ACROSS OUR WESTERN ZONES AS CONVECTION MAY END UP HAVING TO
MOVE INTO THESE AREAS FROM THE WEST. THE BOUNDARY MAY THEN STALL IN
OUR VICINITY OR EVEN WASH OUT AS RIDGING TRIES TO BUILD AGAIN
TUESDAY INTO WEDNESDAY AHEAD OF ANOTHER COLD FRONT AND ADDITIONAL
TROUGH AMPLIFICATION. THIS FRONT LOOKS TO ARRIVE INTO OUR AREA
WEDNESDAY OR PERHAPS A LITTLE BEYOND DEPENDING ON THE TIMING. AS A
RESULT, LOW CHC POPS WERE INCLUDED FOR WEDNESDAY. WHILE THE AREAL
COVERAGE AND TIMING CARRIES SOME UNCERTAINTY, THERE APPEARS TO BE AN
INCREASING CHC OF SHOWERS AND THUNDERSTORMS MONDAY THROUGH WEDNESDAY.

&&

.AVIATION /10Z THURSDAY THROUGH MONDAY/...
THE FOLLOWING DISCUSSION IS FOR KPHL, KPNE, KTTN, KABE, KRDG, KILG,
KMIV, KACY AND SURROUNDING AREAS.

THE ONSHORE FLOW HAS BEGUN AND IN TYPICAL FASHION, LOW CIGS HAVE
BEEN JUMPING UP AND DOWN ALL NIGHT IN OUR SOUTHERN AND EASTERN AREAS.
MOST CONDITIONS HAVE BEEN VFR NORTH AND WEST, BUT HAVE DROPPED TO
MVFR AND EVEN TO IFR IN SOME LOCATIONS SOUTH AND EAST. EXPECT MAINLY
VFR AFTER SUNRISE UNTIL THE SHOWERS AND TSTMS BEGIN TO TAKE OVER.
HAVE A FEW STARTING TO DEVELOP IN OUR NORTHERN AREAS RIGHT NOW, BUT
MOST OF THE ACTIVITY WILL BE MOVING IN FROM THE WEST DURING THE DAY.
WINDS WILL BE FROM THE EAST AT AROUND 10 KT.

OUTLOOK...
COULD SEE A REPEAT PERFORMANCE TONIGHT WITH THE STRATUS AND FOG,
AS THE BOUNDARY LAYER FLOW REMAINS EAST AROUND THE SURFACE
HIGH TO THE NORTH. AFTER THIS, COULD SEE SOME DRIER AIR TRY TO WORK
SOUTHWEST WITH THE HIGH. OVERALL, EXPECTING CONDITIONS TO BECOME
VFR AGAIN FRIDAY WITH ONLY A FEW SCATTERED SHOWERS POSSIBLE.
COULD BE LOOKING AT DRIER CONDITIONS FOR AT LEAST THE START OF THE
UPCOMING WEEKEND.

&&

.MARINE...
ENJOY THE QUIET CONDITIONS WHILE YOU CAN. AN ONSHORE EASTERLY FLOW
HAS SET IN AND WILL CONTINUE WELL INTO THE WEEKEND. THE PRESSURE
GRADIENT WILL ALSO TIGHTEN A BIT. THIS WILL CAUSE WINDS TO INCREASE
AND SEAS TO BUILD. WINDS MAY MAX OUT IN THE 20 TO 25 KT RANGE BUT
SEAS ARE NOW FORECAST TO BUILD TO 5 OR 6 FT ON OUR OCEAN WATERS.
FOR THIS REASON A SMALL CRAFT ADVISORY WILL GO INTO EFFECT AT
6 AM FRIDAY. FOR NOW, THE ADVISORY WILL REMAIN IN EFFECT THROUGH
FRIDAY NIGHT BUT COULD BE EXTENDED SINCE SEAS ARE FORECAST TO
REMAIN HIGH THROUGH THE WEEKEND.

HIGH PRESSURE TO OUR NORTH WILL BE THE DOMINANT FEATURE INTO THE
UPCOMING WEEKEND. THERE IS SOME INDICATION OF A DROP IN THE GRADIENT
AS THE SURFACE HIGH MOVES FURTHER AWAY FROM NORTHERN NEW ENGLAND COAST
SATURDAY NIGHT AND SUNDAY. THIS WOULD ALLOW WINDS TO DIMINISH A BIT
BUT SEAS WILL TAKE LONGER TO DROP OFF AS THE EASTERLY SWELL WILL BE
WELL DEVELOPED...AND COULD LAST INTO SUNDAY.

&&

.TIDES/COASTAL FLOODING...
WITH TIDES CURRENTLY RUNNING OVER 1/2 FOOT ABOVE NORMAL AND AN
ONSHORE FLOW DEVELOPING, MINOR TIDAL FLOODING WILL BE A CONCERN
FOR THE NEXT FEW DAYS. OCEAN FRONT SECTIONS OF NEW JERSEY, AND TO A
LESSER EXTENT DELAWARE, HAD MINOR SPILLOVER LAST EVENING. ALL
INDICATIONS ARE THAT THE TIDAL DEPARTURES WILL BE INCREASING AS
THE ONSHORE FLOW INCREASES. IT ALSO APPEARS THAT WATER PUSHED INTO
DELAWARE BAY WILL PRODUCE SOME MINOR TIDAL FLOODING THERE ALSO.
FOR THIS REASON, A COASTAL FLOOD ADVISORY HAS BEEN ISSUED FOR
THE NEXT TWO HIGH TIDE CYCLES ALONG THE NEW JERSEY AND DELAWARE
OCEAN FRONTS AND ON DELAWARE BAY. THIS ALSO INCLUDES THE BACK BAYS.
THE NEXT HIGH TIDE CYCLE THIS MORNING IS THE LOWER OF THE TWO DAILY
HIGH TIDES. EVEN SO, WATER LEVELS IN MANY AREAS WILL APPROACH OR
REACH MINOR TIDAL FLOOD HEIGHTS. THE HIGH TIDE CYCLE EARLY TONIGHT
SHOULD SEE EVEN HIGHER LEVELS, SINCE IT IS THE HIGHER OF THE TWO
TIDES AND TIDAL DEPARTURES SHOULD BE GREATER AT THAT TIME.

HIGH TIDES ALONG THE NJ AND DE COASTS WILL RUN FROM 930 AM TO
1130 AM AND FROM 10 PM TO MIDNIGHT. TIMES ON DELAWARE BAY AND ON
THE BACK BAYS WILL RUN UP TO 2 HOURS LATER.

&&

.RIP CURRENTS...
AS THE EASTERLY FETCH INCREASES TODAY INTO FRIDAY...THE RIP CURRENT
THREAT COULD INCREASE TO MODERATE. THIS APPEARS TO BE MORE LIKELY
FRIDAY THAN TODAY.

&&

.CLIMATE...
CORRECTED RTP WAS SENT THIS PAST WED EVENING FOR THE MAX TEMP AT
KACY. 5P CLIPHL DID NOT CATCH THE HIGH OF 96 TODAY THAT OCCURRED
AFTER THE 5PM OB AS ASSOCIATED CLIPHL.

A QUICK CHECK OF CLI FOR THE FIRST 11 DAYS...PHL ALREADY ABOVE NORMAL
FOR THE MONTH OF AUGUST ON NUMBER 90 OR HIGHER DAYS. NORMAL IS ABOUT
5 AND 6 HAVE OCCURRED. ALSO FOR THE YEAR TO DATE...42 SO
FAR...NORMAL AROUND 21.
