Rip Current in Delaware, September 5 to 6, 2012

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MOUNT HOLLY NJ
351 AM EDT WED SEP 5 2012

.SYNOPSIS...
LOW PRESSURE OVER NEW ENGLAND EARLY TODAY WILL CONTINUE TO MOVE
NORTHEAST THROUGH TONIGHT. AN ATTACHED FRONT WILL SLOWLY CROSS THE
AREA THIS AFTERNOON AND TONIGHT. THE FRONT WILL STALL SOUTH OF THE
AREA THROUGH THE WEEKEND. WEAK HIGH PRESSURE WILL AFFECT THE AREA
THURSDAY AND FRIDAY. LOW PRESSURE WILL DEVELOP ALONG THE STALLED
FRONT AND MOVE BACK TOWARD THE AREA THIS WEEKEND...BRINGING MORE
UNSETTLED WEATHER. TROPICAL SYSTEM LESLIE WILL REMAIN WELL TO THE
EAST THROUGH EARLY NEXT WEEK.

&&

.NEAR TERM /UNTIL 6 PM THIS EVENING/...
AT 300 AM, MOST OF OUR FORECAST AREA WAS IN A BREAK FROM THE SHOWER
AND THUNDERSTORM ACTIVITY. THE ONLY EXCEPTIONS WERE SCATTERED
SHOWERS AND ISOLATED THUNDERSTORMS IN THE POCONOS AND IN FAR
NORTHERN NEW JERSEY, AND SOME ISOLATED RAIN SHOWERS IN THE LEHIGH
VALLEY AND IN SOUTHERN NEW JERSEY.

TODAY SHOULD BE OUR FINAL ROUND OF HEAVY PRECIPITATION IN OUR REGION.

A LOW LEVEL JET EXTENDED FROM THE CAROLINAS UP TO NEW ENGLAND EARLY
THIS MORNING. THE FEATURE WILL LIFT SLOWLY TO THE NORTHEAST TODAY.
AN AXIS OF DEEP MOISTURE COINCIDENT WITH THE LOW LEVEL JET WILL
REMAIN OVER OUR REGION THIS MORNING, THEN IT SHOULD DRIFT SLOWLY
TO THE EAST.

SURFACE LOW PRESSURE LOCATED OVER THE ADIRONDACKS EARLY THIS MORNING
WILL PROGRESS TO THE EAST, REACHING CANADA'S MARITIME PROVINCES LATE
IN THE DAY. THE LOW IS FORECAST TO PULL A WEAKENING FRONTAL BOUNDARY
INTO OUR REGION FOR TODAY.

PRECIPITABLE WATER VALUES ARE EXPECTED TO REMAIN AT OR ABOVE 2
INCHES IN MUCH OF OUR REGION FOR THIS MORNING, WITH A GRADUAL
DECREASE FROM THE NORTHWEST IN THE AFTERNOON. WITH ABUNDANT LOW
LEVEL MOISTURE, MODERATE INSTABILITY, THE SURFACE BOUNDARY AND WEAK
IMPULSES TRAVELING IN THE MID LEVEL FLOW, WE HAVE THE INGREDIENTS
FOR SHOWERS AND SCATTERED THUNDERSTORMS ALONG WITH HEAVY DOWNPOURS.

WE WILL KEEP THE FLASH FLOOD WATCH IN PLACE FOR THE PHILADELPHIA
METROPOLITAN AREA WITH URBAN LOCATIONS REMAINING THE MOST
SUSCEPTIBLE TO FLASH FLOODING IN OUR CURRENT SITUATION. HOWEVER,
LOCALIZED FLOODING REMAINS POSSIBLE IN THE REMAINDER OF OUR FORECAST
AREA, AS WELL.

SOME BREAKS OF SUNSHINE TODAY SHOULD ALLOW TEMPERATURES TO RISE INTO
THE LOWER AND MIDDLE 80S AT MOST LOCATIONS.

&&

.SHORT TERM /6 PM THIS EVENING THROUGH 6 AM THURSDAY/...
AS THE AXIS OF DEEP MOISTURE CONTINUES TO DRIFT TO OUR EAST TONIGHT,
THE THREAT OF HEAVY RAIN WILL COME TO AN END. IMPULSES IN THE MID
LEVEL FLOW WILL CONTINUE TO NUDGE THE MOISTURE AND THE WEAKENING
SURFACE FRONT OFF THE COAST. THE CHANCE FOR PRECIPITATION WILL
DECREASE FROM NORTHWEST TO SOUTHEAST.

THE AIR BEHIND THE FRONTAL BOUNDARY IS ONLY SLIGHTLY COOLER AND
SLIGHTLY LESS HUMID THAT THE AIR AHEAD OF IT. AS A RESULT, IT SHOULD
BE ANOTHER MILD NIGHT, WITH LOW TEMPERATURES MAINLY IN THE 60S.

&&

.LONG TERM /THURSDAY THROUGH TUESDAY/...
WEAK HIGH PRESSURE AND SLIGHT H5 RIDGING ACROSS THE REGION
THURSDAY AND FRIDAY WILL PROVIDE SOME DEGREE OF RELIEF FROM THE
RECENT SPELL OF HUMID/SHOWERY WEATHER. THE SFC FRONT WILL BE
STALLED SOUTH OF THE AREA THROUGH THE PERIOD. ITS NOT A STRONG
RIDGE ALOFT AND WITH WARM TEMPERATURES AT THE SFC...SOME
AFTERNOON AND EARLY EVENING SHOWERS OR A TSTM MAY BE TRIGGERED.
THE SLGT CHC POPS WERE LEFT IN THE GRIDS FOR NOW. TEMPERATURES
THU/FRI ABOVE NORMAL.

AN UPPER TROUGH DEVELOPING TO THE WEST FRI WILL MOVE EASTWARD AND
COLLECT THE SFC FRONT STALLED TO THE SOUTH. THIS WILL PRODUCE
SHOWERS/TSTMS FOR SAT INTO SUN NIGHT. CHC POPS ARE IN THE GRIDS
FOR THESE PERIODS NOW. SOME HEAVY RAINS ARE POSSIBLE FOR THESE
PERIODS.

&&

.AVIATION /08Z WEDNESDAY THROUGH SUNDAY/...
THE FOLLOWING DISCUSSION IS FOR KPHL, KPNE, KTTN, KABE, KRDG, KILG,
KMIV, KACY AND SURROUNDING AREAS.

CONDITIONS WERE MVFR AT 0730Z AT KABE AND KMIV. VFR CONDITIONS WERE
REPORTED AT OUR OTHER SIX TAF SITES. MVFR CEILINGS SHOULD EXPAND
OVER OUR REGION DURING THE EARLY MORNING HOURS. SHOWERS FROM THE
NORTHWEST WILL HAVE AN INCREASING IMPACT ON KRDG AND KABE.

WE ARE EXPECTING ANOTHER ROUND OF SHOWERS AND THUNDERSTORMS WITH
HEAVY RAIN TODAY AS A FRONTAL BOUNDARY WORKS ITS WAY SLOWLY THROUGH
OUR REGION FROM NORTHWEST TO SOUTHEAST. AS A RESULT, CONDITIONS FOR
AVIATION WILL AGAIN BE LESS THAN IDEAL. WE WILL INDICATE PREVAILING
VFR CEILING AND VISIBILITY VALUES. HOWEVER, CONDITIONS WILL LIKELY
DROP TO MVFR OR IFR AT TIMES NEAR AND IN SHOWERS AND THUNDERSTORMS.

A VERY GRADUAL IMPROVEMENT FROM THE NORTHWEST IS FORECAST TO TAKE
PLACE DURING THE AFTERNOON. THE PRECIPITATION SHOULD BEGIN TO PASS
OFF THE COAST LATE IN THE DAY.

CONDITIONS ARE FORECAST TO BE MAINLY VFR FOR THIS EVENING.
OVERNIGHT, LINGERING LOW LEVEL MOISTURE MAY RESULT IN SOME LOW
CLOUDS AND PATCHY OF FOG.

OUTLOOK...
THU THROUGH FRI NIGHT...MOSTLY VFR BUT OVERNIGHT FOG IS POSSIBLE.
SAT THROUGH SUN..VFR AT TIMES...BUT LOWER CONDITIONS IN SCATTERED SHOWERS
AND ISOLATED TSTMS WITH MVFR/IFR POSSIBLE.

&&

.MARINE...
A SOUTH TO SOUTHWEST FLOW IS EXPECTED TO CONTINUE ON THE COASTAL
WATERS OF NEW JERSEY AND DELAWARE FOR TODAY AND TONIGHT. WIND SPEEDS
TODAY SHOULD BE MAINLY IN THE 10 TO 20 KNOT RANGE. SPEEDS ARE
FORECAST TO DECREASE TO AROUND 10 KNOTS FOR TONIGHT.

WAVE HEIGHTS ON OUR OCEAN WATERS ARE EXPECTED TO REMAIN IN THE 4 TO
6 FOOT RANGE WITH A LONG PERIOD SOUTHEASTERLY SWELL. THE SWELL
PERIOD EARLY THIS MORNING WAS AROUND 14 SECONDS. WE WILL CONTINUE
THE SMALL CRAFT ADVISORY ON OUR OCEAN WATERS. WAVE HEIGHTS ON
DELAWARE BAY SHOULD BE MOSTLY IN THE 1 TO 3 FOOT RANGE, POSSIBLY
CLOSE TO 4 FEET NEAR THE MOUTH OF THE BAY.

OUTLOOK...
LONG PERIOD SWELLS TO SCA CRITERIA WILL LIKELY EXTEND INTO THE
WEEKEND AND EARLY NEXT WEEK ON THE OCEAN. SUB-SCA CONDITIONS
EXPECTED ON DEL BAY...WITH A FEW HIGHER SWELL WAVES NEAR THE
MOUTH OF THE BAY.

&&

.HYDROLOGY...
ANOTHER ROUND OF HEAVY SHOWERS AND THUNDERSTORMS IS EXPECTED FOR
TODAY. RAINFALL AMOUNTS OF AN INCH OR TWO MAY BE COMMON. THERE IS
THE POSSIBILITY OF LOCALIZED HIGHER AMOUNTS. WITH HIGH PRECIPITABLE
WATER VALUES AND THE POTENTIAL FOR TRAINING ECHOES, SOME LOCATIONS
COULD PICK UP 2 TO 4 INCHES OF RAIN IN A SHORT AMOUNT OF TIME. WITH
THE WET CONDITIONS OF THE PAST FEW DAYS, LOCALIZED FLOODING REMAINS
A THREAT. AS OF EARLY THIS MORNING, FLOODING CONTINUED IN
SOUTHEASTERN BURLINGTON COUNTY IN NEW JERSEY DUE TO RUNOFF FROM THE
RECENT HEAVY RAINFALL.

&&

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