A protracted rain event from the daylight hours on the 6th through the early morning on the 8th culminated with heavy rain during the afternoon and evening of the 7th and caused poor drainage flooding in New Jersey. It also caused minor to locally moderate river and creek flooding in the Raritan and Passaic River Basins in northern New Jersey and minor creek and river flooding in southwest New Jersey. Flooding in the Passaic Basin persisted into the early morning of the 11th. Event precipitation totals averaged 2 to 3 inches. The rain was caused by waves of low pressure that moved northeast along a slowly moving frontal boundary. The cold front was in central Pennsylvania on the morning of the 6th and eastern Pennsylvania on the morning of the 7th. The last wave of low pressure on this boundary, located over western North Carolina at 7 a.m. EST on the 7th intensified rapidly as the 7th progress. It was during this intensification process that rain fell at its heaviest that afternoon and evening. The low pressure system itself passed through Delaware during the early evening of the 7th and was over the Monmouth County, New Jersey coastal waters at 10 p.m. EST on the 7th. It reached Long Island, New York at 1 a.m. EST on the 8th. Shortly after the low reached Long Island, the rain ended across New Jersey.

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MOUNT HOLLY NJ
849 PM EST WED DEC 7 2011
.SYNOPSIS...
A COLD FRONT WILL DRIFT OFFSHORE THIS EVENING. LOW PRESSURE WILL
TRACK NORTHEASTWARD ALONG THIS FRONT AND INTENSIFY RAPIDLY AS IT
MOVES OFF THE NEW JERSEY COAST LATE THIS EVENING. THE STORM IS
EXPECTED TO MOVE TO THE NORTHERN NEW ENGLAND COAST THURSDAY
MORNING AND PASS INTO THE CANADIAN MARITIMES DURING THURSDAY. HIGH
PRESSURE BUILDING TOWARD THE CENTRAL MID ATLANTIC LATER THURSDAY
WILL BE OVER OUR AREA THURSDAY NIGHT AND FRIDAY. A WEAK COLD FRONT
WILL MOVE THROUGH FRIDAY NIGHT INTO SATURDAY. A STRONG RIDGE OF
HIGH PRESSURE WILL SET UP FROM THE CANADIAN MARITIMES
SOUTHWESTWARD TO THE LOWER MISSISSIPPI VALLEY SUNDAY INTO
WEDNESDAY...AND CONTRAST WITH POTENTIAL LOW PRESSURE IN THE
WESTERN ATLANTIC.
&&
.NEAR TERM /UNTIL 6 AM THURSDAY MORNING/...
IT LOOKS LIKE THE CONVECTION POTENTIAL IS GOING BY THE BOARDS AS
THE BEST INSTABILITY APPEARS TO BE GETTING CUT OFF TO THE SOUTH.
THERE ARE SOME CONVECTIVE LOOKING LINES IN DELAWARE AND SOUTHERN
NEW JERSEY...BUT NO WIND REPORTS OUT OF THESE AREAS SO FAR.
OTHERWISE...THE BEST MID LEVEL FRONTOGENETIC FORCING IS MOVING
ACROSS EAST CENTRAL PENNSYLVANIA AT THIS TIME. THIS IS RESULTING IN
THE AREA OF MODERATE TO HEAVY RAIN THAT COVERS MUCH OF THE
FORECAST AREA. THE BACK EDGE OF THE PRECIPITATION IS STILL BACK
OVER SOUTHWEST VIRGINIA...SO THE PRECIPITATION WILL CONTINUE INTO
THE EARLY MORNING HOURS.
WHILE KMPO IS NOT SHOWING SNOW YET...THE RADAR IMAGES SUGGEST THAT
SNOW IS PROBABLY FALLING IN THE HIGHER TERRAIN OF CARBON AND MONROE
COUNTIES NOW. GIVEN THE HIGH PRECIPITABLE WATER VALUES IN THE
FRONTOGENETIC FORCING...AND AN ISOTHERMAL LAYER IN THE LOWER TO
MID LEVELS...HEAVY SNOW SHOULD COMMENCE IN THESE AREAS SHORTLY.
BECAUSE OF THIS...THERE HAS BEEN NO SUBSTANTIAL CHANGE TO THE
SNOWFALL FORECAST HERE. THE HIGHEST AMOUNTS WILL BE ACROSS THE
HIGHER TERRAIN...AS LOWER ELEVATIONS MAY BE JUST ABOVE FREEZING
FOR MOST OF THE SNOWFALL. SNOWFALL AMOUNTS COULD BE A TAD HIGH IF
THE CHANGEOVER IS DELAYED...BUT THERE IS NO REASON TO THINK THIS
NOW.
THE WINTER WEATHER ADVISORY WILL REMAIN IN PLACE AS IT IS. THE
ONLY OTHER CONCERNS FOR TONIGHT MAY BE A BIT MORE SNOW THAN WE ARE
CURRENTLY ADVERTISING FOR THE HIGHER TERRAIN OF CHESTER...AS WELL
AS UPPER BUCKS AND UPPER MONTGOMERY COUNTIES. THE COLD AIR COULD
GET INTO THE REGION JUST IN TIME FOR A CHANGE IN THE HIGHER
TERRAIN. FOR NOW...AN INCH OF SNOW WAS INSERTED INTO THESE
AREAS...AND TRENDS WILL BE MONITORED.
AS THE LOW PULLS AWAY LATER TONIGHT THE ISALLOBARIC WINDS REALLY
RAMP UP IN THE WAKE OF TREMENDOUS PRESSURE RISES. GUSTS UPWARDS OF
45 MPH CAN BE EXPECTED ACROSS THE DELMARVA ZONES CLOSER TO THE
VERY TIGHT PRESSURE GRADIENT. AS FAST AS THE LOW PULLS OUT TO SEA
TOMORROW MORNING WILL BE AS FAST AS CONDITIONS IMPROVE. SKIES WILL
RAPIDLY CLEAR AND THE PRECIPITATION WILL COME TO AN END BY
DAYBREAK.
&&
.SHORT TERM /6 AM THURSDAY MORNING THROUGH 6 PM THURSDAY/...
THE LOW PRESSURE WILL BE COMPLETELY OUT OF THE REGION BY DAYBREAK
GIVING WAKE TO A FRESH CANADIAN AIRMASS. THE NORTHWEST FLOW WITH BE
GUSTY AT TIMES TOMORROW BUT ULTIMATELY RELAXING AS THE PRESSURE
GRADIENT RELAXES. WITH THAT BEING SAID, TEMPERATURES WILL BE NEARLY
15 TO 20 DEGREES COLDER THAN ON WEDNESDAY.
CONDITIONS WILL REMAIN DRY ON THURSDAY EVEN WITH STEEP LAPSE RATES
IN PLACE, THERE IS NOT ENOUGH MOISTURE IN THE LOW AND MID-LEVELS TO
SEE ANY INSTABILITY SHOWERS.
&&
.LONG TERM /THURSDAY NIGHT THROUGH WEDNESDAY/...
WITH A RIDGE OF HIGH PRESSURE EXPECTED TO PREVAIL THROUGH MOST OF
THE LONG TERM PERIOD...MORE QUIESCENT WEATHER WILL OCCUR AFTER
TONIGHTS POTENT LOW MOVES THROUGH. A WEAK FRONT IS EXPECTED FRIDAY
NIGHT INTO SATURDAY, BUT THIS DRY FEATURE WILL INCREASE THE
NORTHWEST TO NORTH FLOW SATURDAY FOR A WHILE. OTHERWISE...LOW
PRESSURE DEVELOPING OVER THE WESTERN ATLANTIC WILL CONTRAST WITH
THE RIDGE AND MAY PROVIDE INCREASED NORTHEAST WINDS AND ROUGHER
WATERS FOR OUR OCEAN ZONES...AS WELL AS HIGHER THAN NORMAL TIDES.
WITH A FAIRLY ZONAL UPPER FLOW OVER THE AREA THROUGH THE LONG TERM
PERIOD...TEMPERATURES WILL BE NEAR OR BELOW SEASONAL NORMALS. HPC
TEMPERATURES WERE ACCEPTED...WITH HIGHS FORECAST TO BE IN THE 30S
TO LOW 40S NORTH TO THE 40S TO NEAR 50 SOUTH.
&&
.AVIATION /02Z THURSDAY THROUGH MONDAY/...
THE FOLLOWING DISCUSSION IS FOR KPHL, KPNE, KTTN, KABE, KRDG,
KILG, KMIV, KACY AND SURROUNDING AREAS.
THE SURFACE BOUNDARY STRETCHES FROM FROM JUST NORTH OF KACY
THROUGH KDOV. NORTH OF THE FRONT...CONDITIONS REMAINS IFR WITH
CEILINGS GENERALLY BELOW 1000 FEET. WHILE CEILINGS MAY OCCASIONALLY
TRY TO JUMP UP TO VFR AT TIMES...THIS SHOULD BE LIMITED AN LEAVE
ONCE THE STEADIER RAIN ARRIVES FROM NORTHEAST MARYLAND. THE LOW
LEVEL WINDS HAVE SHIFTED TO NORTH NORTHEAST...AND THE SURFACE
PRESSURE GRADIENT SHOULD INCREASES THROUGH ABOUT 0400 UTC AS
SURFACE LOW PRESSURE APPROACHES.
THE FRONT SHOULD DROP SOUTH OF THE KMIV AND KACY BEFORE 0300 UTC.
IT LOOKS LIKE THE STEADIEST RAIN STAYS NORTH OF THESE LOCATIONS...
BUT CEILINGS WILL RESULT IN IFR CONDITIONS THERE AS WELL. AFTER
0400 UTC...THE PRECIPITATION WILL START TO END FROM WEST TO EAST.
THE RAIN COULD CHANGE TO SNOW BRIEFLY BEFORE IT ENDS AT KRDG AND
KABE...WHICH COULD RESULT IN A BRIEF PERIOD OF LIFR CONDITIONS AT
THESE LOCATIONS.
AS THE SURFACE LOW MOVES NORTHEAST OF THE AREA AFTER 0600 UTC...
WINDS WILL SHIFT TO NORTHWEST AT ALL LOCATIONS. CONDITIONS SHOULD
IMPROVE FAIRLY QUICKLY AT MOST TERMINAL SITES...WITH KRDG AND KABE
POSSIBLY HOLDING ON TO MVFR CONDITIONS A BUT LONGER. THE WIND WILL
BE THE ISSUE AFTER 0600 UTC...AND FROM KPHL SOUTH AND EAST...A
PERIOD OF 35 KNOT GUSTS ARE EXPECTED THROUGH ABOUT 1000 UTC.
AFTER 1000 UTC...AS WEAK HIGH PRESSURE BUILDS TOWARD THE AREA FROM
THE LOWER OHIO VALLEY...THE GRADIENT WILL SUPPORT WIND GUSTS NEAR
23 KNOTS THROUGH EARLY AFTERNOON. LITTLE IN THE WAY OF CLOUD COVER
IS EXPECTED WITH CONVECTIVE TEMPERATURES WELL OUT OF REACH.
OUTLOOK...
VFR WEATHER WILL EXIST THURSDAY NIGHT THROUGH MONDAY. A WEAK COLD
FRONT FRIDAY NIGHT INTO SATURDAY SHOULD BE DRY BUT WILL SERVE TO
ENERGIZE THE WINDS SOMEWHAT SATURDAY. OTHERWISE EXCELLENT FLYING
CONDITIONS ARE FORECAST OVER THE WEEKEND AND INTO EARLY NEXT WEEK.
&&
.MARINE...
SMALL CRAFT CONDITIONS WILL EVENTUALLY GIVE WAY TO GALES LATER
TONIGHT. ALTHOUGH THERE IS A BREAK IN THE RAIN THIS AFTERNOON THE
PROGRESSING LOW PRESSURE WILL BEGIN TO UNDERTAKE A DEEPENING PROCESS
AS IT NEARS OUR COAST. THIS WILL GENERATE ANOTHER AREA OF ENHANCED
RAINFALL LATE TONIGHT INTO TOMORROW MORNING. THIS IS THE SAME TIME
PERIOD IN WHICH THE WINDS WILL BEGIN TO STRENGTHEN TO GALES.
AS THE LOW PULLS FURTHER TO OUR NORTHEAST TOMORROW MORNING WINDS
SWING TO THE NORTHWEST AND CONTINUE TO HOWL. LARGE PRESSURE RISES
COUPLED WITH STRONG COLD AIR ADVECTION WILL CONTINUE TO MAKE FOR
TREACHEROUS CONDITIONS ON THE SEAS. SEAS WILL FALL FROM THEIR PEAK,
AROUND 8 FEET TONIGHT, TO AROUND 3 FEET BY THURSDAY AFTERNOON. THIS
IS WHEN THE WINDS BEGIN TO RELAX AS THE PRESSURE GRADIENT LESSENS.
THERE WILL STILL BE SMALL CRAFT GUSTS THROUGH THE REMAINDER OF
THURSDAY.
FOR THURSDAY NIGHT THROUGH MONDAY, MARINE CONDITIONS ARE FORECAST
TO BE GENERALLY BELOW SMALL CRAFT ADVISORY CRITERIA. OFFSHORE
WINDS MAY INCREASE SOMEWHAT SATURDAY AFTER A WEAK COLD FRONT
PUSHES THROUGH...BUT A RIDGE OF HIGH PRESSURE WILL SET UP
THEREAFTER INTO EARLY NEXT WEEK. LOW PRESSURE DEVELOPING OVER THE
WESTERN ATLANTIC COULD CAUSE A PRESSURE GRADIENT WHICH WOULD
INCREASE NORTHEAST WINDS AND ESPECIALLY SEAS ABOVE LEVELS FORECAST
AT THIS TIME...AND POSSIBLY TO ADVISORY CRITERIA...BUT WITH LOW
CONFIDENCE, A MIDDLE ROAD APPROACH WAS TAKEN FOR NOW.
&&
.HYDROLOGY...
TO THIS POINT...ONE AND ONE-HALF TO TWO AND ONE-HALF INCHES OF
RAIN HAS FALLEN ACROSS THE WESTERN TWO THIRDS OF THE FORECAST
AREA. THE RUNOFF IS GETTING INTO THE CREEKS AND STREAMS...AND AREAL
FLOOD WARNINGS HAVE BEEN ISSUED FOR THIS. THE NEXT CONCERN IS SOME
OF THE SMALLER RIVERS...WHICH COULD GET PUSHED INTO FLOOD WITH THE
BAND OF HEAVY RAIN OVER THE AREA NOW...AND THE ONE THAT IS
PUSHING THROUGH EAST CENTRAL MARYLAND.
