While all the highest crests with Irene occurred in August, river and creek flooding persisted into September in parts of Atlantic, Burlington, Cumberland, Morris and Salem Counties. Flooding in Morris County persisted the longest into the 5th and ended just before the flooding associated with the remnants of Tropical Storm Lee began.

NWS Philadelphia/Mount Holly wrote its last area forecast discussion before the first event at Aug 31, 11:56 PM EST, 4 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE MOUNT HOLLY NJ 1256 AM EDT THU SEP 1 2011 .SYNOPSIS... HIGH PRESSURE OVER THE AREA TONIGHT WILL GRADUALLY RETREAT INTO NEW ENGLAND THURSDAY. MEANWHILE, A WEAK DISTURBANCE IS FORECAST TO CROSS THE REGION LATE THURSDAY. A COLD FRONT WILL THEN APPROACH FROM THE WEST LATE SATURDAY AND MOVE THROUGH OUR REGION LATE SUNDAY. THIS FRONT SHOULD BE SETTLING SOUTH AND EAST OF THE AREA ON LABOR DAY, AS HIGH PRESSURE BUILDS ACROSS THE GREAT LAKES TO THE NORTHEAST TUESDAY AND WEDNESDAY. && .NEAR TERM /UNTIL 6 AM THIS MORNING/... HIGH PRESSURE AT THE SURFACE WILL MOVE OFF THE NEW ENGLAND COAST TONIGHT, WHILE A SHORTWAVE CONTINUES IN THE SAME DIRECTION. THIS SHORTWAVE SHOULD BRING MOST OF THE CLOUD COVER OVER OUR AREA TO OUR NORTH OVERNIGHT, ALTHOUGH SOME CIRRUS CAN BE EXPECTED. WE ARE NOT ANTICIPATING ANY PRECIPITATION TONIGHT, AND WITH LITTLE CLOUD COVER, WE SHOULD COOL FAIRLY NICELY AND END UP WITH A NIGHT SIMILAR TO LAST NIGHT. A MAV/MET MOS BLEND WAS TAKEN FOR TEMPERATURES. && .SHORT TERM /6 AM THIS MORNING THROUGH 6 PM FRIDAY/... THURSDAY SHOULD BE VERY SIMILAR TO WEDNESDAY. MOSTLY CLEAR SKIES SHOULD BEGIN TO FILL IN DURING THE DAY WITH MID/LOW LEVEL CLOUDS, AND THICKEN THROUGH THE DAY AS A SHORTWAVE WITH THE MID/UPPER TROUGH MOVES INTO THE AREA. WE ARE NOT OVERLY IMPRESSED BY PRECIPITATION CHANCES DURING THE DAY THURSDAY, AS THE HIGHEST MOISTURE CONTENT IN THE ATMOSPHERE SHOULD REMAIN TO OUR WEST FOR MUCH OF THE DAY. NEVERTHELESS, WE DO KEEP A SLIGHT CHANCE OF SHOWERS/THUNDERSTORMS FOR OUR EXTREME NORTHWEST ZONES DURING THE AFTERNOON. A MAV/MET MOS BLEND WAS TAKEN FOR TEMPERATURES. && .LONG TERM /FRIDAY NIGHT THROUGH WEDNESDAY/... THE OVERALL SYNOPTIC SETUP INVOLVES A TROUGH IN THE NORTHEAST THURSDAY NIGHT, WHICH THEN GIVES WAY TO A RIDGE FOR A TIME. THIS RIDGE THEN GETS KNOCKED DOWN AS WE GO THROUGH THE HOLIDAY WEEKEND WITH THE PASSAGE OF A COLD FRONT. THERE IS THEN INCREASING UNCERTAINTY AS WE GET CLOSER TO THE END OF THIS TIME FRAME DUE TO WHAT HAPPENS WITH THE TIMING AND AMPLIFICATION OF THE TROUGH ALONG WITH POSSIBLE SURFACE LOW ALONG THE FRONT. MODEL AND ENSEMBLE GUIDANCE HAS BEEN WAFFLING DURING THE LAST SEVERAL DAYS REGARDING HOW MUCH ENERGY AND MOISTURE ALONG AND SOUTH OF THE GULF COAST MAY GET PULLED NORTHEASTWARD BY THE TROUGH IN THE EASTERN U.S. SO FAR CONTINUITY AND CONSENSUS HAS FAVORED KEEPING THE BEST DEFINED SURFACE LOW OVER THE WESTERN GULF. HOWEVER GIVEN THE PRESENCE OF AN EASTERN TROUGH, THERE IS STILL THE POTENTIAL FOR SOUTHEASTERN ENERGY TO EVOLVE IN SUCH A WAY TO SUPPORT A SEPARATE SURFACE LOW NEAR THE EAST COAST WEDNESDAY. SOME OF THE OPERATIONAL MODELS ARE SHOWING THIS, HOWEVER THERE IS A SIGNIFICANT SPREAD AMONG THEM. GIVEN THE MODEL GUIDANCE VARIABILITY ON THIS, THERE IS RATHER LOW CONFIDENCE. AS NOTED BY HPC, RELATIVE AGREEMENT OF THE ENSEMBLE GUIDANCE AND HIGH SPREAD SEEN IN THE OPERATIONAL MODELS POINTS TOWARD A BLEND OF THE GEFS/ECMWF ENSEMBLE MEANS FROM LATE SATURDAY THROUGH WEDNESDAY. FOR THURSDAY NIGHT AND FRIDAY...A RIDGE BUILDING INTO THE GREAT LAKES AND OHIO VALLEY WILL BE SLIDING EASTWARD, HOWEVER ENERGY TOPPING THE RIDGE MAINTAINS A TROUGH SLIDING OFF THE NEW ENGLAND AND MID ATLANTIC COASTS. WHILE A FEW SHOWERS OR WEAKENING THUNDERSTORMS MAY TRY AND MOVE INTO AT LEAST OUR NORTHWEST ZONES, IT APPEARS THE LIFT IS WEAK UNDER THE INCOMING RIDGE AXIS AND SOME LINGERING HINTS OF SURFACE HIGH PRESSURE WEDGED DOWN INTO OUR AREA. AT THIS POINT, WE FAVORED JUST SOME SLIGHT CHC POPS ACROSS THE NORTHWEST FOR A TIME THURSDAY NIGHT. FOR SATURDAY AND SUNDAY...A COLD FRONT WILL BE APPROACHING OUR AREA FROM THE WEST AND NORTHWEST. THIS FEATURE MAY BE SLOW AT FIRST MOVING INTO THE AREA AS RIDGING HOLDS FOR AWHILE AND THE TROUGH IN THE MIDWEST AND WESTERN GREAT LAKES AMPLIFIES FAR ENOUGH TO OUR WEST. AN AXIS OF WAA AND INCREASING MOISTURE ADVECTION SHOULD COMBINE WITH BETTER SURFACE CONVERGENCE TO INITIATE SHOWERS AND THUNDERSTORMS ALONG THE FRONT. SOME OF THIS MAY EDGE CLOSE TO OUR NORTHWEST ZONES LATE SATURDAY, HOWEVER DESPITE THE HINTS OF A LEE SIDE TROUGH, IT APPEARS ANY CONVECTION SHOULD BE RATHER LIMITED. THE CHCS FOR CONVECTION INCREASES DURING SUNDAY AS THE FRONT MOVES INTO THE AREA ALONG WITH HEIGHT FALLS. A LEE SIDE TROUGH MAY TEND TO BECOME MORE ACTIVE AS WELL. GIVEN DEEPENING MOISTURE AND SOME INCREASE IN THE WIND FIELDS ABOVE THE SURFACE, THERE MAY BE SOME ROBUST CONVECTIVE ELEMENTS. FOR MONDAY THROUGH WEDNESDAY...THERE IS RATHER LOW CONFIDENCE AS WE GO THROUGH THIS TIME FRAME. THE MODEL GUIDANCE OVERALL VARIES REGARDING THE ENERGY AMPLIFYING ACROSS THE GREAT LAKES INTO THE NORTHEAST AS WELL WITH MOISTURE MOVING NORTHEASTWARD FROM THE GULF OF MEXICO. THE COLD FRONT FROM LATE SUNDAY SHOULD BE SETTLING TO OUR SOUTH AND EAST MONDAY, HOWEVER SOME OF THE GUIDANCE SUGGEST THAT THIS STALLS AND NEVER CLEARS OUR CWA. THIS SCENARIO WOULD END UP AS A MORE UNSETTLED ONE AS MOISTURE GETS TANGLED UP FROM A POSSIBLE GULF OF MEXICO SYSTEM AND STREAMS NORTHWARD ACROSS OUR AREA. THIS WOULD OPEN THE DOOR FOR ANOTHER ROUND OF HEAVY RAIN. WE ARE NOT SO CERTAIN THIS WILL OCCUR ATTM BUT THE POTENTIAL IS THERE. FOR NOW, GENERALLY LEANED MORE TOWARD HPC GUIDANCE IN PUSHING THE FRONT FAR ENOUGH SOUTH AND EAST TUESDAY AND WEDNESDAY AS HIGH PRESSURE BUILDS ACROSS THE GREAT LAKES AND NORTHEAST. MONDAY IS A LITTLE TRICKY AS SOME LINGERING SHOWERS COULD OCCUR ESPECIALLY IN THE MORNING DEPENDING ON THE EXACT MOVEMENT OF THE FRONT. && .AVIATION /06Z THURSDAY THROUGH MONDAY/... THE FOLLOWING DISCUSSION IS FOR KPHL, KPNE, KTTN, KABE, KRDG, KILG, KMIV, KACY AND SURROUNDING AREAS. MAINLY HIGH AND MID LEVEL CLOUDS ABOUT TO EXIT TO THE EAST OF THE AREA EARLY THIS MORNING. BEHIND THE MAIN CLOUD AREA...PATCHY MID LEVEL CLOUDS WILL PROBABLY CONTINUE TO MOVE EAST THROUGH SUNRISE. IT IS NOT CLEAR JUST HOW MUCH THIS WILL INTERFERE WITH RADIATIONAL COOLING (AND THE POTENTIAL FOR MVFR CONDITIONS IN PATCHY FOG). RIGHT NOW...THE LOWER LEVELS WERE A BIT MORE MOIST IN THE LOWER LEVELS (WITH RESPECT TO DEW POINT). WITH THIS IN MIND...PATCHY MVFR CONDITIONS IN FOG WERE ADDED TO THE 0600 UTC FORECAST FOR KRDG...AND MAY HAVE TO BE ADDED TO KABE AND KMIV AT SOME POINT. THE FOG WILL BE LEFT OUT OF THE LATTER TWO TERMINALS AND ADDED AS NEEDED. OTHERWISE...MAINLY HIGH AND PATCHY MID LEVEL CLOUDS TODAY WITH A WARM FRONT TO THE WEST. IT DOES NOT LOOKS A THOUGH CONVECTIVE TEMPERATURES WILL BE REACHED TODAY...SO THERE SHOULD BE A MINIMUM OF CUMULUS...ESPECIALLY SOUTH AND EAST OF KABE AND KRDG. THERE COULD BE WIDELY SCATTERED SHOWERS ACROSS THE NORTHERN LEHIGH VALLEY AND SOUTHERN POCONOS LATE THIS AFTERNOON AND EVENING...BUT THIS SHOULD NOT AFFECT THE TERMINALS. VFR CONDITIONS ARE EXPECTED TONIGHT AS A MID LEVEL DISTURBANCE DIVES TO THE SOUTHEAST ACROSS THE LEHIGH VALLEY. THIS SHOULD RESULT IN SCATTERED TO BROKEN MID LEVEL CLOUDS...BUT AT THIS POINT IT APPEARS AS THOUGH ANY SHOWERS SHOULD REMAIN WEST OF THE AREA. THE MOST LIKELY TERMINALS TO BE AFFECT BY SHOWERS WOULD BE KRDG AND KABE (AND PERHAPS KILG). FOR NOW...THE SHOWERS WERE LEFT OUT OF THE FORECAST/ OUTLOOK... THURSDAY NIGHT AND FRIDAY...A WEAK SYSTEM MOVES ON BY WITH PERHAPS AN ISOLATED SHOWER OR THUNDERSTORM MAINLY NEAR KABE AND KRDG THURSDAY EVENING. SATURDAY AND SUNDAY...A COLD FRONT APPROACHES LATER SATURDAY THEN MOVES THROUGH LATE SUNDAY. A SURFACE TROUGH MAY DEVELOP WELL AHEAD OF THE COLD FRONT SUNDAY AND HELP TO FOCUS SOME SHOWERS AND THUNDERSTORMS. OTHERWISE SOME SHOWERS AND THUNDERSTORMS AHEAD OF AND ALONG THE COLD FRONT SUNDAY WITH AREAS OF SUB-VFR CONDITIONS. LOWER CONFIDENCE AT THIS TIME REGARDING THE TIMING AND AREAL COVERAGE. MONDAY...THE COLD FRONT SHOULD SETTLE SOUTH AND EAST OF THE AREA, HOWEVER PERHAPS LINGERING CLOUDS AND A FEW SHOWERS IN THE MORNING. THERE IS LOW CONFIDENCE DURING THIS TIME FRAME, GIVEN UNCERTAINTY ON HOW MUCH ACTIVITY IS LEFT WITH THE FRONT AND HOW FAR SOUTH AND EAST THE FRONT IS OF OUR AREA. && .MARINE... LIGHT AND VARIABLE CONDITIONS ON THE WATERS ARE EXPECTED TO BEGIN TO PICKUP OUT OF THE EAST TO NORTHEAST LATER TONIGHT INTO THURSDAY. SEAS ARE EXPECTED TO REMAIN AROUND 3 TO 4 FEET, BUT WITH A RATHER LONG PERIOD SWELL DUE TO THE LONG FETCH FROM THE EAST-NORTHEAST. OUTLOOK... HIGH PRESSURE CENTERED UP INTO NEW ENGLAND WILL TRANSLATES EASTWARD AS AN UPPER-LEVEL TROUGH SHIFTS EASTWARD NEAR THE AREA. THIS WILL ALLOW FOR AN EASTERLY FLOW TO OCCUR THURSDAY NIGHT THROUGH FRIDAY. AS OF NOW, THIS FLOW LOOKS TO BE ON THE LIGHTER SIDE THEREFORE SEAS SHOULD STAY UNDER 5 FEET. AN UPPER-LEVEL RIDGE MOVES OVER THE AREA SATURDAY AHEAD OF A COLD FRONT. THEREFORE, THE FLOW IS EXPECTED TO SHIFT FROM THE SOUTH SATURDAY AND SUNDAY WITH SOME INCREASE. THE OVERALL GRADIENT AND LACK OF A STRONG SURFACE HIGH TO OUR EAST SUGGESTS THAT THE WINDS REMAIN BELOW SMALL CRAFT ADVISORY CRITERIA. A LEE SIDE TROUGH SHOULD FORM INLAND SUNDAY AHEAD OF THE COLD FRONT, THEN THE FRONT MOVES THROUGH LATE SUNDAY AND MONDAY MORNING. THERE IS LOWER CONFIDENCE REGARDING THE TIMING OF THIS FRONT, AS IT MAY EVEN STALL IN OUR AREA. DEPENDING ON THE LOCATION OF THIS FRONT, A WIND SHIFT TO THE NORTHWEST WILL OCCUR WITH SOME INCREASE ON MONDAY. THIS FLOW MAY ALLOW FOR SOME INCREASE IN THE SEAS, BUT FOR NOW GENERALLY KEPT THEM BELOW 5 FEET. && .HYDROLOGY... PLEASE SEE REMAINING FLS/FLW'S AS POSTED ON THE KPHI WEB SITE. && .TIDES/COASTAL FLOODING... SOME OF THE MODEL GUIDANCE WE ARE REVIEWING OFFERS INCREASING SURGE DEPARTURES THURSDAY INTO SATURDAY AS WE CROSS THRU THE NEW MOON HIGHER ASTRO TIDE PHASE. THE PERSISTENT NE-E FLOW ASSOCIATED WITH LOW PRESSURE DEVELOPING NEAR 38N/65W THE NEXT COUPLE OF DAYS WILL PROBABLY INCREASE THE SURGE DEPARTURES HERE AND MAY NECESSITATE THE NEED FOR SEVERAL CF ADVISORIES THURSDAY INTO SATURDAY...THE LOW DEL RIVER FROM PHL TO REEDY POINT AND MAYBE SANDY HOOK REGION. WE MAY ADD THIS TO OUR HWO LATER THIS EVENING. && .RIP CURRENTS...
