Areal Flood Advisory 4, NWS Philadelphia/Mount Holly

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MOUNT HOLLY NJ
346 PM EDT SUN JUL 6 2008

.SYNOPSIS...
A FRONTAL BOUNDARY WILL PERSIST IN OUR AREA TONIGHT, THEN WEAKEN
DURING MONDAY AS IT MAY LIFT SLOWLY NORTHWARD. AS THIS OCCURS,
HIGH PRESSURE IN THE WESTERN ATLANTIC WILL BUILD TOWARD OUR AREA
MONDAY INTO TUESDAY. A COLD FRONT IS FORECAST TO ARRIVE ON
WEDNESDAY AND POSSIBLY STALL TO OUR SOUTH AS HIGH PRESSURE ARRIVES
FROM THE NORTHWEST THURSDAY AND FRIDAY. THE AFOREMENTIONED FRONT
MAY THEN TEND TO LIFT BACK NORTHWARD SATURDAY INTO SUNDAY AS A
WARM FRONT.

&&

.NEAR TERM /UNTIL 6 AM MONDAY MORNING/...
A SURFACE MAP ANALYSIS THIS AFTERNOON PLACES A STATIONARY FRONT
ACROSS FAR SOUTHERN NEW JERSEY, BACK ACROSS DELAWARE AND MARYLAND,
THEN DOWN THROUGH VIRGINIA AND INTO THE TENNESSEE VALLEY. A MESOLOW
DEVELOPED ACROSS THE DELMARVA IN CONJUNCTION WITH THE DEEPENING
PORTION OF THE UPPER-LEVEL TROUGH. WATER VAPOR IMAGERY SHOWS THE
UPPER-LEVEL LOW BECOMING BETTER ORGANIZED OVER THE OHIO VALLEY, WITH
A DEEP PLUME OF TROPICAL MOISTURE SURGING NORTHWARD ON ITS EASTERN
SIDE. THE MESOLOW AND ENHANCED LOW-LEVEL CONVERGENCE HAS BEEN THE
FOCUS FOR SOME HEAVY SHOWERS AND THUNDERSTORMS IN EASTERN
MARYLAND AND DELAWARE THIS AFTERNOON. INSTABILITY AROUND THE
REGION ON AVERAGE IS BETWEEN 1000 TO 2000 J/KG. AN EASTERLY FLOW
AND CLOUD COVER EARLIER LIMITED THE INSTABILITY NORTH AND EAST OF
PHILADELPHIA, HOWEVER MORE INSTABILITY HAS DEVELOPED OVER THE
PAST FEW HOURS.

THE FORECAST SOUNDINGS CONTINUE TO ADVERTISE A THIN CAPE PROFILE AS
THE ATMOSPHERIC COLUMN REMAINS RATHER MOIST. THE INSTABILITY IS
FORECAST TO LINGER FOR AWHILE TONIGHT BUT BECOMES LESS THAN ABOUT
200 J/KG ON AVERAGE. THE BULK OF THE CONVECTION THAT OCCURS INTO THIS
EVENING IS DIURNALLY INDUCED, THEREFORE WE ARE EXPECTING MUCH OF IT
TO WEAKEN THROUGH THIS EVENING. WE WILL NEED TO WATCH YET ANOTHER
SHORT WAVE MOVING NORTHEASTWARD ON THE EAST SIDE OF THE UPPER-LEVEL
TROUGH. THE GFS YESTERDAY WAS RIGHT ABOUT THIS ONLY TO FAR NORTH
WITH IT. NOW THE NAM HAS THE SHORT WAVE BETTER DEPICTED. THIS MAY
POP ISOLATED TO SCATTERED SHOWERS OR A THUNDERSTORM OVERNIGHT,
ESPECIALLY ACROSS OUR SOUTHERN/SOUTHEAST ZONES. AS A RESULT, WE
WILL KEEP A MENTION IN THE FORECAST WITH THE HIGHEST POPS THROUGH
EARLY THIS EVENING.

THE LOW CLOUDS AND FOG PLAYED OUT VERY WELL LATE LAST NIGHT AND THIS
MORNING, AS THE ETA MOS DEPICTED. TONIGHT WE ARE EXPECTING THE LOW
CLOUDS TO REDEVELOP GIVEN A VERY SIMILAR AIRMASS EVEN THOUGH THE
LOW-LEVEL WINDS ARE SHIFTING TO A MORE SOUTHERLY DIRECTION. LOW
TEMPERATURES ARE EXPECTED TO BE SIMILAR TO WHAT WE SAW THIS
MORNING.

&&

.SHORT TERM /6 AM MONDAY MORNING THROUGH TUESDAY NIGHT/...
THE RELENTLESS UPPER-LEVEL TROUGH REMAINS TO OUR WEST ON MONDAY. AS
WE START WITH A GOOD AMOUNT OF CLOUDS AND SOME FOG ACROSS THE BULK
OF THE CWA, WE SHOULD TRANSITION TO AT LEAST SOME HAZY SUNSHINE IN
THE AFTERNOON. THE PERSISTENT SURFACE BOUNDARY THAT HAS BEEN
STALLED IN THE VICINITY SHOULD EITHER SLIDE NORTHWARD OR DISSIPATE
ON MONDAY AS THE LOW-LEVEL FLOW BECOMES MORE SOUTHERLY. THE MODEL
GUIDANCE IS HINTING AT AT LEAST SCATTERED CONVECTION POPPING ON
MONDAY, HOWEVER THE AREAL COVERAGE MAY ONCE AGAIN BE OVERDONE.
WHILE THERE WILL BE INSTABILITY, IT APPEARS TO NOT BE ENOUGH TO
PROMOTE VERY STRONG UPDRAFTS AS THE CAPE PROFILE IS YET AGAIN VERY
THIN. WE MAY HAVE ISOLATED PULSE STORMS AS THE CORES BUILD AND
THEN COLLAPSE /I.E. WHAT WE SAW TODAY/. THE CONTINUED WEAK FLOW
THROUGH THE ATMOSPHERIC COLUMN WILL PROMOTE SLOW PROPAGATING
STORMS WITH ANY COLLAPSES/DOWNPOURS TOSSING OUT OUTFLOW
BOUNDARIES. OTHER THAN OUTFLOW BOUNDARIES, THERE IS A LACK OF
LOW-LEVEL CONVERGENCE TO GET ORGANIZED CONVECTION GOING. GIVEN
THE PATTERN THOUGH, WE WILL NEED TO KEEP AT LEAST CHC POPS IN FOR
SCATTERED CONVECTION INTO MONDAY EVENING WITH THE BEST CHC OF
CONVECTION BEING FROM ABOUT MIDDAY INTO THE EARLY EVENING.

WE MAY SEE SOME FOG FORM AGAIN MONDAY NIGHT HOWEVER THE LOW CLOUDS
ARE NOT EXPECTED TO BE NEARLY AS WIDESPREAD AS THE BOUNDARY LAYER
FLOW IS MORE SOUTHWEST. THE ENTIRE UPPER-LEVEL TROUGH THEN FINALLY
WEAKENS MONDAY NIGHT AND TUESDAY. EVEN SO, THE PRESENCE OF THE
UPPER TROUGH OVERHEAD AND BUILDING HEAT TUESDAY, WE CANNOT RULE
OUT SOME CONVECTION POPPING UP DURING THE AFTERNOON HOURS. AGAIN,
A RATHER THIN CAPE PROFILE INDICATED, HOWEVER FORECAST SOUNDINGS
SHOW A DEVELOPMENT OF SOME DRIER AIR WITHIN THE BOUNDARY LAYER
/INVERTED-V TYPE SIGNATURE/ WHICH COULD LEAD TO SOME GUSTY WINDS
WITH THE STRONGER CONVECTION. ANY ACTIVITY THAT POPS UP SHOULD
DIMINISH FAIRLY QUICKLY IN THE EVENING WITH THE LOSS OF DAYTIME
HEATING.

AS FOR TEMPERATURES, WE UTILIZED A BLENDED APPROACH FOR MONDAYS
HIGHS AS THERE IS A SIGNIFICANT DIFFERENCE BETWEEN THE ETA MOS AND
GFS/NGM MOS. THE FLOW IS EXPECTED TO BE MORE SOUTHERLY, THEREFORE
MOST PLACES SHOULD BE ABLE TO GET INTO THE 80S. THE ETA MOS KEEPS
THE LOWER CLOUDS AROUND LONGER, WHICH HAS BEEN THE CASE FOR AT
LEAST A PART OF THE CWA TODAY. THEREFORE WE WENT WITH A BLEND TO
LEAN A LITTLE TOWARD THE COOLER MOS. WE CONTINUED WITH THE WARMER
MOS ON TUESDAY AS WE ARE ON THE WESTERN SIDE OF THE WESTERN
ATLANTIC RIDGE. THE AMOUNT OF CUMULUS THAT POPS THOUGH WOULD HAVE
AN IMPACT ON HOW HIGH TEMPERATURES GO. FORECAST HEAT INDICES TOP
OUT AROUND 95 DEGREES TUESDAY AFTERNOON IN THE URBANIZED AREAS, AND
WE WILL CONTINUE TO MENTION THIS IN THE HAZARDOUS WEATHER OUTLOOK.

&&

.LONG TERM /WEDNESDAY THROUGH SUNDAY/...
AN EXPANSIVE UPPER-LEVEL RIDGE THAT BUILT TOWARD THE MID ATLANTIC
DURING THE SHORT TERM WILL GET KNOCKED DOWN SOME WEDNESDAY AS AN
UPPER-LEVEL TROUGH MOVES ACROSS THE GREAT LAKES REGION. HOT AND
HUMID CONDITIONS WILL PERSIST THOUGH WEDNESDAY AHEAD OF AN
ADVANCING SURFACE COLD FRONT. THE OVERALL MODEL GUIDANCE CONTINUES
TO BE IN DECENT AGREEMENT WITH THE LARGER FEATURES, WHICH MAINLY
INVOLVES A SLIGHTLY AMPLIFYING UPPER-LEVEL TROUGH MOVING ACROSS
THE MIDWEST TO NEW ENGLAND WEDNESDAY THROUGH THURSDAY. THIS WILL
ULTIMATELY DRIVE A COLD FRONT ACROSS OUR AREA WEDNESDAY NIGHT.
SOME EARLIER GUIDANCE WAS SUGGESTING THAT THE COLD FRONT ITSELF
MAY MOVE A LITTLE SLOWER, HOWEVER SOME NEWER GUIDANCE IS BACK ON
TRACK WITH THE FRONTAL BOUNDARY ARRIVING INTO OUR CWA LATE
WEDNESDAY AFTERNOON. THE GFS AND UKMET PORTRAY A PROGRESSIVE FLOW
ALONG THE CANADIAN BORDER. HPC NOTED THAT THE ECMWF/GFS ENSEMBLE
MEANS, THE 00Z ECMWF AND THE GEM GLOBAL ALL ESTABLISH A MEAN
TROUGH OVER THE PACIFIC NORTHWEST DURING THE SECOND HALF OF THE
PERIOD. THE GEM GLOBAL LOOKS OVERDONE WITH THE AMPLITUDE OF ITS
TROUGH OVER THE NORTHWEST BY THE START OF SATURDAY. HPC UTILIZED A
BLEND OF THE ECMWF AND ECMWF ENSEMBLE MEAN THROUGH AT LEAST
FRIDAY, THEN SHIFTED TO THE MOST RECENT ECMWF ENSEMBLE MEAN
THEREAFTER TO ADDRESS THE UNCERTAINTY AT THAT TIME RANGE.

BASED ON THE ABOVE, A COLD FRONT WILL GRADUALLY MOVE INTO THE AREA
ON WEDNESDAY. GIVEN THE SYNOPTIC PATTERN, THERE SHOULD BE A
DEVELOPING LEE SIDE TROUGH IN THE MID ATLANTIC REGION. THIS LEE SIDE
TROUGH MAY ACTUALLY BE THE MAIN FOCUS FOR CONVECTIVE DEVELOPMENT AS
THE COLD FRONT ITSELF MAY HOLD BACK TO OUR WEST A BIT LONGER. THE
MID AND UPPER LEVEL JETS ARE FORECAST TO REMAIN NORTH AND WEST OF
OUR AREA WEDNESDAY, HOWEVER SOME STRONGER UPPER- LEVEL WINDS ARE
FORECAST TO NEAR IN THE EVENING. THE ADVERTISED PATTERN COULD BE
CHARACTERISTIC OF SOME CONVECTIVE COMPLEXES THAT DEVELOP IN THE
GREAT LAKES REGION AND SLIDE EASTWARD, GIVEN THE MUCH STRONGER
FLOW THERE. THERE STILL REMAINS UNCERTAINTIES WITH THE INITIATION
POINTS THOUGH ALONG WITH THE PLACEMENT OF INDIVIDUAL SHORT WAVES.
IF SOME CONVECTIVE COMPLEXES DO FORM ACROSS THE GREAT LAKES, THEN
CLOUD DEBRIS COULD SPILL DOWNSTREAM. STILL, THE EXPECTATION OF A
LEE SIDE TROUGH WITH A VERY WARM AND HUMID AIRMASS IN PLACE SHOULD
ALLOW FOR SOME CONVECTION TO POP, SOME OF WHICH COULD BE STRONG TO
SEVERE. WE WILL CONTINUE WITH CHC POPS SPREADING FROM WEST TO EAST
WEDNESDAY INTO WEDNESDAY NIGHT.

THE AFOREMENTIONED COLD FRONT SHOULD CLEAR OUR ENTIRE AREA LATE
WEDNESDAY NIGHT AND PERHAPS STALL TO OUR SOUTH DURING THURSDAY. A
SURFACE HIGH IS FORECAST TO BUILD TOWARD OUR AREA THURSDAY AFTERNOON
WHICH MAY THEN PUSH THE LOW-LEVEL BOUNDARY A BIT MORE SOUTHWARD.
HIGH PRESSURE THEN SLIDES OVER THE AREA ON FRIDAY, BEFORE GRADUALLY
TRACKING TO OUR EAST SATURDAY. THE LEFTOVERS OF THE FRONTAL BOUNDARY
SHOULD LIFT NORTHWARD AS A WARM FRONT DURING SATURDAY, WITH A WARM
SOUTHWESTERLY FLOW BECOMING MORE ESTABLISHED SUNDAY.

THAT IS ALL FOR NOW. THANKS TO THE SURROUNDING OFFICES FOR THE
COLLABORATION TODAY. HAVE A GOOD ONE

&&

.AVIATION /20Z SUNDAY THROUGH FRIDAY/...
THE EASTERLY FLOW THAT THE NAM CORRECTLY FORECAST HAS CREATED SOME
CONVECTIVE INHIBITION /CIN/ AROUND THE AREA, WITH THE GREATEST AXIS
RUNNING FROM ALONG I195 INTO THE PHL AREA AND THEN UP INTO THE NWRN
TAF SITES AT 17Z. THAT CIN WAS WEAKEST AT THE MIV, ACY AND ILG
SITES. THE NAM PROGS CIN TO WEAKEN WITH TIME DURING THE COURSE OF
THE AFTERNOON, AND OUR TIMING OF INCLUSION OF CB OR VCTS AND OUR
CHOICE OF WHERE TO INCLUDE TEMPO GROUPS FOR TSTMS DEPENDED TO A FAIR
EXTENT ON THIS FORECAST. AFTER AROUND 01Z, WE AGAIN LEAN TOWARD
CLIMATOLOGY AND BEGIN TO SHUT DOWN THE CONVECTION. CAPES DROP BELOW
250 J/KG BEYOND THAT TIME PER THE NAM BUFKIT. THERE IS, AGAIN, AN
IMPULSE THAT THE NAM KICKS OUT OF THE MID LEVEL LOW TO OUR WEST AND
RUNS TOWARD OUR SOUTHERN LOCALES BY AROUND 12Z MON, BUT WHAT WERE
FORECASTING OVERNIGHT IS FOR STRATUS AND FOG TO REDEVELOP. THE NAM
SFC WINDS WERE BECOMING OR ARE FORECAST TO BECOME MORE SOUTHERLY
WITH TIME TONIGHT, BUT THEY STILL MAINTAIN A SUFFICIENT, ALBEIT
WEAK, ONSHORE COMPONENT TO SUPPORT THIS. SO DOES THE INITIAL
PROXIMITY OF OUR WEAK SURFACE BOUNDARY.

OUTLOOK...
WE ARE FORECASTING THE FRONTAL ZONE TO WEAKEN AND LIFT NORTH BY
TOMORROW AS A LARGE BERMUDA HIGH PRESSURE SYSTEM TAKES OVER THE
CIRCULATION. THIS WILL BRING AN INCREASINGLY WARM AND HUMID FLOW TO
OUR AREA AND CONTINUE THE THREAT OF SHOWERS AND THUNDERSTORMS
THROUGH MIDWEEK. A COLD FRONT APPROACHING FROM THE NORTHWEST MAY
WORK ITS WAY INTO THE FORECAST AREA WEDNESDAY NIGHT.

&&

.MARINE...
THE FRONT OVER OUR WATERS IS FORECAST TO WEAKEN GRADUALLY AND LIFT
NORTH BY TOMORROW AS A BERMUDA HIGH TO THE SOUTHEAST AND ASSOCIATED
MID LEVEL RIDGE GRADUALLY BUILD. THE NAM IS GIVING UP THE EASTERLY
COMPONENT TO THE WINDS BY TOMORROW. WE THEREFORE ARE CARRYING SOUTH
WINDS OR SOUTHEAST WINDS BECOMING SOUTH FOR TONIGHT, THEN
FORECASTING A SOUTHERLY FLOW TO BE DOMINANT OVER ALL THE WATERS INTO
THE MID-WEEK PERIOD. EVENTUALLY, WHAT IS LEFT OF THE MID LEVEL LOW
TO THE WEST AND AN ASSOCIATED COLD FRONT SHOULD MOVE ACROSS OUR AREA
AND CAUSE WINDS TO SHIFT TO THE WEST. THIS PROBABLY WILL HAPPEN
AROUND WEDNESDAY NIGHT. WINDS THROUGH THE FORECAST ARE PROGGED TO BE
LIGHT TO MODERATE AND SEAS ARE CAPPED BELOW THE ADVISORY CRITERION.
WE CONTINUE TO FORECAST A CHANCE OF SHOWERS AND THUNDERSTORMS,
ESPECIALLY IN THE AFTERNOON AND EVENING PERIODS, AND WE CONTINUE TO
FORECAST SOME FOG EARLY IN THE FORECAST, ESPECIALLY IN THE OVERNIGHT
AND MORNING PERIODS.

&&

.HYDROLOGY...
PRECIPITABLE WATER VALUES WILL CONTINUE TO RUN NEAR 2.0 INCHES
TONIGHT RIGHT THROUGH TUESDAY. GIVEN THE WEAK WIND FLOW, ANY
STRONGER CONVECTIVE ELEMENTS WILL BE CAPABLE OF PRODUCING LOCALLY
TORRENTIAL RAINFALL AS THEY SLOWLY PROPAGATE. AS A RESULT, LOCALIZED
FLOODING WILL BE POSSIBLE.
