Special Weather Statement, NWS Philadelphia/Mount Holly

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MOUNT HOLLY NJ
1153 AM EDT MON SEP 3 2012

.SYNOPSIS...
A STATIONARY FRONT REMAINS DRAPED TODAY FROM THE LOWER DELMARVA TO
THE UPPER OHIO VALLEY. LOW PRESSURE TO OUR WEST WILL GRADUALLY
TRACK TO THE NORTHEAST THROUGH WEDNESDAY, PULLING THE STATIONARY
FRONT NORTHWARD AS A WARM FRONT TONIGHT AND TUESDAY. AS THE LOW
REACHES THE VICINITY OF MAINE AND THE CANADIAN MARITIMES WEDNESDAY
NIGHT, IT IS EXPECTED TO PULL A TRAILING FRONTAL BOUNDARY THROUGH
OUR REGION. A COLD FRONT FROM THE NORTHWEST IS FORECAST TO ARRIVE
EARLY FRIDAY, FOLLOWED BY A WEAK AREA OF HIGH PRESSURE. ANOTHER
COLD FRONT MAY APPROACH FROM THE WEST SUNDAY.

&&

.NEAR TERM /UNTIL 6 PM THIS EVENING/...
HIGH PRESSURE CENTERED ACROSS EASTERN NEW ENGLAND IS WEDGED AT THE
SURFACE SOUTHWESTWARD INTO THE NORTHERN MID ATLANTIC STATES.
MEANWHILE, A STATIONARY FRONT IS DRAPED FROM THE LOWER DELMARVA
WESTWARD TO THE NORTHERN OHIO VALLEY WITH THE REMNANT LOW OF
ISSAC NEAR WESTERN KENTUCKY. THE 12Z STERLING, VA RAOB INDICATED A
MOIST ENVIRONMENT WITH A WEALTH OF MOISTURE FROM THE SURFACE UP TO
NEAR 600 MB. IN ADDITION, A PW VALUE OF 2.04 INCHES WAS INDICATED.

A FOCUSED AREA OF LOW-LEVEL CONVERGENCE ALONG WITH DEEP MOISTURE
IN THE DELAWARE VALLEY HAS BEEN LEADING TO A MORE ORGANIZED AREA
OF HEAVY SHOWERS SO FAR. THIS AREA OF HEAVY SHOWERS SHOULD TEND TO
WEAKEN SOME WITH A NORTHERN EXTEND DUE TO THE LOSS OF A MORE DEFINED
FOCUS AND MORE OF AN INFLUENCE OF HIGH PRESSURE. AN UPSLOPE FLOW
COMPONENT IS ALSO PROBABLY ENHANCING THIS TO SOME EXTENT. GIVEN
THE RATHER HIGH MOISTURE CONTENT IN THE AIR ALONG WITH A SLOW
STORM MOTION, DOWNPOURS WILL OCCUR WITH LOCALIZED FLOODING. THE
LIKELY POPS WILL CONTINUE FOR A TIME WITH THIS, THEN SHIFT
SOUTHWESTWARD WITH ADDITIONAL DEVELOPMENT NOW OCCURRING. FARTHER
NORTHEAST, SHOWERS SHOULD TEND TO BE MORE SPOTTY THEREFORE
MAINTAINED SOME LOWER POPS. WHILE OVERALL THERE IS SOME
INSTABILITY, CONVECTION IN MAY NOT BE TALL ENOUGH TO RESULT IN
CHARGE SEPARATION. SOME BREAKS IN THE CLOUDS HOWEVER ACROSS THE
DELMARVA AND ALSO VIRGINIA HAS ALLOWED SOME STRONGER CONVECTIVE
ELEMENTS TO DEVELOP INCLUDING CLOUD TO GROUND LIGHTNING. WE WILL
CONTINUE TO MENTION A SLIGHT CHC/CHC FOR ISOLATED/SCATTERED
THUNDER ESPECIALLY ACROSS SOUTHWESTERN PORTIONS OF THE CWA.

GIVEN THE RATHER MOIST AIRMASS, PLENTY OF CLOUDS ARE EXPECTED TO
PREVAIL THROUGH THE DAY. SOME CLEARING HAS OCCURRED ACROSS
SOUTHERN DELAWARE AND THE NEARBY COASTAL WATERS BUT ANY HEATING
SHOULD ALLOW FOR MORE CLOUDS TO FILL IN WITH PERHAPS AN UPTICK IN
CONVECTIVE DEVELOPMENT. THE HOURLY GRIDS WERE TWEAKED WITH SOME
INCORPORATION OF THE LAMP/LAV GUIDANCE. NO MAJOR CHANGES WERE MADE
TO THE HIGH TEMPERATURES ATTM.

&&

.SHORT TERM /6 PM THIS EVENING THROUGH 6 AM TUESDAY/...
THE PATTERN WILL CONTINUE FOR TONIGHT WITH YET MORE MOISTURE
ASSOCD WITH THE UPPER TROF SPREADING NEWD ACROSS THE AREA. HAVE
FCST SLGTLY HIGHER POPS FOR NJ/PA VS DELMARVA FOR TONIGHT...BUT
CONFIDENCE IS NOT TOO HIGH FOR THAT DISTINCTION. WITH PLENTY OF
MOISTURE AVAILABLE...ANY SHOWERS/T-STMS WILL BE CAPABLE OF
PRODUCING VERY HEAVY RAIN AND POSSIBLY LOCALIZED FLOODING.
ALSO...WITH CLOUDY SKIES AND SELY WINDS DURG THE NIGHT MIN TEMPS
EARLY TUE MORN SHOULD BE SIMILAR TO THIS MORN.

&&

.LONG TERM /TUESDAY THROUGH SUNDAY/...
TUESDAY, TUESDAY NIGHT AND WEDNESDAY REMAIN A PERIOD OF CONCERN
FOR OUR REGION WITH THE THREAT OF EXCESSIVE RAINFALL. AT THIS
TIME, WE HAVE LOW CONFIDENCE IN FORECASTING THE EXTENT, TIMING AND
LOCATION OF THE HEAVIEST RAINFALL. HOWEVER, IT SEEMS FAIRLY LIKELY
THAT SOMEWHERE IN OUR AREA OF RESPONSIBILITY THERE WILL BE
FLOODING. FOR NOW, WE WILL CONTINUE TO HIGHLIGHT THE THREAT IN OUR
HAZARDOUS WEATHER OUTLOOK. A FLOOD WATCH MAY EVENTUALLY BE ISSUED.

THERE WILL BE DEEP AND ABUNDANT MOISTURE OVER OUR REGION FOR
TUESDAY AND WEDNESDAY. PRECIPITABLE WATER VALUES SHOULD BE NEAR OR
IN EXCESS OF TWO INCHES FOR MUCH OF THE TIME.

WEAK SURFACE LOW PRESSURE, ASSOCIATED WITH THE REMNANTS OF
TROPICAL SYSTEM ISAAC SHOULD MOVE FROM THE OHIO RIVER VALLEY ON
TUESDAY TO NEW ENGLAND ON WEDNESDAY. MEANWHILE, IMPULSES IN THE
MID LEVEL FLOW SHOULD HELP TRIGGER THE DEVELOPMENT OF SHOWERS AND
THUNDERSTORMS. WITH ABUNDANT MOISTURE, THEY WILL LIKELY PRODUCE
HEAVY RAIN IN SPOTS. ON TUESDAY, THERE IS FORECAST TO BE VERY
LITTLE ATMOSPHERIC FLOW OVER OUR REGION, SO ANY SHOWERS AND
THUNDERSTORMS WILL BE VERY SLOW MOVING. THE ATMOSPHERIC FLOW MAY
INCREASE A BIT DURING TUESDAY NIGHT AND WEDNESDAY.

WE ARE ANTICIPATING THAT PARTS OF OUR REGION WILL RECEIVE FROM
TWO TO FOUR INCHES OF RAIN FROM TUESDAY INTO WEDNESDAY WITH
LOCALLY HIGHER AMOUNTS.

THE SURFACE LOW IS EXPECTED TO REACH THE COAST OF MAINE AND
CANADA'S MARITIME PROVINCES ON WEDNESDAY NIGHT. IT SHOULD PULL A
TRAILING FRONTAL BOUNDARY THROUGH OUR REGION AT THAT TIME. AS THE
MID LEVEL FLOW INCREASES, IT WILL LIKELY HELP TO PUSH THE BOUNDARY
OFF THE COAST ALONG WITH THE DEEP MOISTURE, REDUCING THE THREAT OF
FLOOD IN OUR REGION.

WE WILL KEEP A LOW CHANCE OR SLIGHT CHANCE OF PRECIPITATION IN
THE FORECAST FOR THURSDAY AS A COLD FRONT APPROACHES FROM THE
NORTHWEST. THE BOUNDARY SHOULD PASS THOUGH OUR REGION FROM LATE
THURSDAY NIGHT INTO EARLY FRIDAY WITH A DECREASE IN HUMIDITY
FOLLOWING FOR FRIDAY INTO SATURDAY.

WITH ANOTHER COLD FRONT APPROACHING FROM THE WEST OVER THE
WEEKEND, WE HAVE INCLUDED A SLIGHT OR LOW CHANCE OF SHOWERS,
MAINLY FOR SUNDAY.

TEMPERATURES ARE EXPECTED TO REMAIN NEAR OR SLIGHTLY ABOVE NORMAL
DURING THE PERIOD FROM TUESDAY THROUGH SUNDAY.

&&

.AVIATION /16Z MONDAY THROUGH FRIDAY/...
THE FOLLOWING DISCUSSION IS FOR KPHL, KPNE, KTTN, KABE, KRDG,
KILG, KMIV, KACY AND SURROUNDING AREAS.

AN EAST TO SOUTHEAST FLOW AROUND 10 KNOTS WILL CONTINUE TO BRING
IN MOISTURE OFF THE OCEAN. IN ADDITION, THE AIRMASS IS RATHER
MOIST THEREFORE ANY THINNING OR BREAKS IN THE CLOUDS WILL LEAD TO
ADDITIONAL CLOUD DEVELOPMENT. THE CONDITIONS WILL VARY FROM VFR TO
MVFR REGARDING CEILINGS, AND THE VISIBILITIES WILL GENERALLY BE
VFR WITH THE EXCEPTION OF A QUICK REDUCTION TO NEAR 1SM IN
DOWNPOURS.

THERE WILL BE SHOWERS AND A FEW THUNDERSTORMS, WITH THE MOST
NUMEROUS MAINLY FROM THE KPHL AREA ON SOUTH AND WESTWARD. THESE
SHOWERS MAY TEND TO TAPER OFF FOR A TIME LATER THIS EVENING,
BEFORE INCREASING ONCE AGAIN TOWARD DAYBREAK TUESDAY. THE WEALTH
OF MOISTURE ALONG WITH AN ONSHORE FLOW WILL CONTINUE TO RESULT IN
LOWER CEILINGS WITH EVEN SOME REDUCTION IN THE VISIBILITIES
THROUGH TONIGHT.

OUTLOOK...
TUESDAY THROUGH WEDNESDAY...SHOWERS LIKELY WITH A CHANCE OF
THUNDERSTORMS. THERE IS THE POTENTIAL FOR PERIODS OF MODERATE TO
HEAVY RAIN ACCOMPANIED BY MVFR OR IFR CONDITIONS. MVFR OR IFR
CONDITIONS ARE ALSO POSSIBLE IN LATE NIGHT AND EARLY MORNING FOG,
HAZE AND LOW CLOUDS.

WEDNESDAY NIGHT AND THURSDAY...MAINLY VFR WITH A LOW CHANCE OF
SHOWERS AND THUNDERSTORMS. MVFR OR IFR CONDITIONS ARE ALSO
POSSIBLE IN LATE NIGHT AND EARLY MORNING FOG, HAZE AND LOW CLOUDS.

THURSDAY NIGHT AND FRIDAY...MAINLY VFR.

&&

.MARINE...
WINDS HAVE BEGUN TO INCREASE FROM THE ESE AND ARE EXPECTED TO
INCREASE A BIT MORE DURG TODAY. THESE WINDS ARE ASSOCD WITH WEAK
HIGH PRES BUILDING IN FROM THE NE TODAY. SEAS NOW 2-3 FEET OVER THE
COASTAL WATERS ARE ALSO FCST TO INCR TO 3 TO 4 FT TODAY.

WINDS SHOULD BECOME SLY BY LATE TONIGHT AS THE HIGH PRES RETREATS
AND LOW PRES SLOWLY APPROACHES FROM THE W. SEAS WILL REMAIN AROUND
3 TO 4 FEET. SCATTERED SHOWERS WITH HEAVY RAIN WILL LIMIT VSBYS
AND PRODUCE LOCALLY STRONGER WINDS.

OUTLOOK...
A WARM FRONT IS FORECAST TO LIFT SLOWLY OVER THE COASTAL WATERS
OF NEW JERSEY AND DELAWARE ON TUESDAY WITH ANOTHER FRONTAL
BOUNDARY ARRIVING FROM THE WEST ON WEDNESDAY NIGHT. A COLD FRONT
FROM THE NORTHWEST IS ANTICIPATED FOR EARLY FRIDAY. NEVERTHELESS,
WIND SPEEDS AND GUSTS SHOULD REMAIN LESS THAN 25 KNOTS THROUGH THE
PERIOD.

LONG PERIOD SWELLS FROM DISTANT TROPICAL SYSTEM LESLIE ARE
FORECAST TO AFFECT THE COASTAL WATERS OF DELAWARE AND NEW JERSEY
FROM TUESDAY THROUGH FRIDAY. WAVE HEIGHTS ON OUR OCEAN WATERS MAY
BUILD TO 5 FEET OR GREATER DURING THAT PERIOD WITH A SMALL CRAFT
ADVISORY POSSIBLE.

&&

.HYDROLOGY...
A RATHER MOIST AIRMASS WILL REMAIN OVER THE AREA DURING THE NEXT
COUPLE OF DAYS AS A SOUTHERLY LOW-LEVEL FLOW CONTINUES. IN
ADDITION, THE REMNANTS OF ISSAC WILL CONTINUE TO ARRIVE ESPECIALLY
TUESDAY INTO WEDNESDAY. THE PW VALUES NEAR 2 INCHES TODAY ARE
FORECAST TO INCREASE, FROM SOUTHWEST TO NORTHEAST, TO NEAR 2.25
INCHES TONIGHT AND TUESDAY. THIS WILL RESULT IN LOCALLY VERY HEAVY
RAIN ALONG WITH FLOODING OF ROADWAYS AND POOR DRAINAGE AREAS. IF
THE HEAVY RAIN BECOMES FOCUSED WITHIN A WATERSHED, SOME OF OUR
QUICKER RESPONDING WATERWAYS COULD HAVE SOME FLOODING. THIS WILL
CONTINUE TO BE MONITORED, BUT FOR NOW WILL HOLD OFF ON A FLASH
FLOOD WATCH AND CONTINUE A MENTION IN THE HAZARDOUS WEATHER
OUTLOOK. THIS WILL BE REVISITED LATER TODAY.

&&

.RIP CURRENTS...
LONG PERIOD SWELLS FROM DISTANT TROPICAL SYSTEM LESLIE ARE
FORECAST TO AFFECT THE COASTS OF DELAWARE AND NEW JERSEY INTO NEXT
WEEKEND. AS A RESULT, A PROLONGED PERIOD WITH A MODERATE TO HIGH
RISK OF RIP CURRENTS IS ANTICIPATED.
