The episode as NWS PHI wrote it up.
An intense low pressure system brought strong to high northeast winds into southeast Pennsylvania during the evening of the 26th into the early morning of the 27th. The wind and rain caused Philadelphia International Airport to have delays of up to four hours. There were also 200 cancellations. The winds also brought down weak trees, tree limbs and wires and caused scattered outages. Peak wind gusts included 59 mph in Brookhaven (Delaware County), 56 mph in Kennett Square (Chester County), 53 mph in Coatesville (Chester County), 47 mph at the Northeast Philadelphia Airport and 45 mph at the Philadelphia International Airport. The strongest winds ceased once the low pressure system reached New Jersey. | |The strong to high winds were caused by the pressure gradient (difference) between a low pressure system that passed across the southeast part of the state and a high pressure system over nearby New England and southeast Canada. The low itself moved from Texas on Christmas Day northeast into the Tennessee Valley on the 26th. A secondary low pressure system formed in the Carolinas on the 26th and became the main low. This low moved northeast and passed through southern Delaware on the evening of the 26th and across southeast New Jersey overnight on the 26th.

NWS Philadelphia/Mount Holly wrote its last area forecast discussion before the first event at Dec 26, 7:03 PM EST, 57 minutes earlier.
AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MOUNT HOLLY NJ
703 PM EST WED DEC 26 2012
.SYNOPSIS...
A STRONG LOW PRESSURE SYSTEM WILL CROSS THE REGION TONIGHT AND MOVE
OFF TOWARDS THE NORTHEAST THROUGH THURSDAY. HIGH PRESSURE WILL
BRIEFLY BUILD IN FOR FRIDAY AND MOVE TO OUR EAST BY EARLY SATURDAY.
ANOTHER LOW PRESSURE SYSTEM WILL TRACK ACROSS THE SOUTHEASTERN
UNITED STATES AND THEN UP THE MIDDLE ATLANTIC COAST ON SATURDAY. A
RETURN TO HIGH PRESSURE IS EXPECTED FOR SUNDAY AND MONDAY. A COLD
FRONT IS FORECAST TO CROSS THE REGION MONDAY NIGHT OR TUESDAY.
&&
.NEAR TERM /UNTIL 6 AM THURSDAY MORNING/...
WE WILL ALLOW THE WINTER WEATHER ADVISORY TO EXPIRE RIGHT NOW IN
THE LOWEST TIER. THE NEXT TIER UPWARD, BERKS, LEHIGH VALLEY AND
WARREN AND MORRIS WE SUSPECT WILL RETAIN POCKETS OF FREEZING
RAIN THROUGH THE NIGHT. WE ARE GETTING REPORTS OF FREEZING RAIN
MIXING IN INTO THE POCONOS WITH POWER OUTAGES, SO A VERY ROUGH
NIGHT IS IN STORE FOR THE WARNING COUNTIES.
FROM THE SUPPORTIVE UPPER JET STRUCTURE THROUGH THE MID LEVEL
Q-VECTOR CONVERGENCE AND THE CLOSED LOW ATTACHED TO A NEGATIVE TILT
TROUGH TO THE H7 TROWAL TO THE LOWER LEVEL FRONTOGENESIS AND STRONG
LOW LEVEL JET BRINGING UP GOOD MOISTURE, THIS IS A POTENT SYSTEM
HEADING TOWARD US. THE PATH OF THE SURFACE LOW IS NOT CONDUCIVE TO
SNOW FROM NEAR THE I95 CORRIDOR SOUTHEAST, BUT AS ONE MOVES
NORTHWEST THE SNOW GROWTH REGION COINCIDES WELL WITH THE BEST LIFT
AND THE THETA E PROFILE IS ISOTHERMAL. THE ONLY THINGS WORKING
AGAINST HEFTIER SNOW AMOUNTS NORTHWEST ARE THE STRONG WIND FIELD IN
THE SNOW GROWTH REGION, WHICH WOULD TEND TO SHATTER CRYSTALS AND
LOWER THE RATIOS; A POSSIBLE MID LEVEL DRY SLOT ARRIVING AROUND
MIDNIGHT; AND WARMING ABOVE THE SURFACE DUE TO THE STRONG LOW LEVEL
JET THAT IS EXPECTED TO GRADUALLY CHANGE SNOW TO SLEET AND THEN
FREEZING RAIN. FURTHER SOUTHEAST, RAINFALL AMOUNTS OF UP TO TWO
INCHES ARE FORECAST. SEE THE HYDRO SECTION BELOW. MODELS ALSO SHOW
STRONG WINDS MAKING IT DOWN TO THE SURFACE NEAR THE NORTHERN NEW
JERSEY COASTAL REGION. THIS IS NOT SANDY, BUT IT IS A SIGNIFICANT
SYSTEM.
WE HAVE ISSUED A HIGH WIND WARNING FOR MIDDLESEX, MONMOUTH AND
OCEAN COUNTIES AND HAVE MAINTAINED THE WIND ADVISORY FOR SOUTHERN
AND CENTRAL DELAWARE AND THE REST OF EASTERN NEW JERSEY.
&&
.SHORT TERM /6 AM THURSDAY MORNING THROUGH 6 PM THURSDAY/...
WE EXPECT PRECIPITATION TO BE ON THE WANE ON THURSDAY, WITH
LINGERING RAIN NORTHWEST CHANGING BACK TO SNOW SHOWERS. WINDS SHOULD
BE FAIRLY ROBUST ON THURSDAY, ALTHOUGH THE LOWER LEVEL JET WILL NOT
BE AS STRONG AS IT WILL BE IN THE NEAR TERM. ANOTHER WIND ADVISORY
MAY BE ISSUED FOR PARTS OF THE AREA. TEMPERATURES ARE A
CONTINUITY/GUIDANCE BLEND.
&&
.LONG TERM /THURSDAY NIGHT THROUGH WEDNESDAY/...
NOT MANY CHANGES MADE TO THE EXTENDED DUE TO ONGOING WEATHER
CONDITIONS TODAY. UPDATED THE GRIDS AND BLENDED MODEL GUIDANCE WITH
CONTINUITY THROUGH SATURDAY AND THEN BLENDED HPC GUIDANCE ALONG WITH
CONTINUITY FOR SUNDAY THROUGH THE END OF THE PERIOD.
WEAK HIGH PRESSURE BUILDS IN FOR FRIDAY AND EARLY SATURDAY. THE NEXT
STORM SYSTEM DEVELOPS ACROSS THE SOUTHEASTERN UNITED STATES AND
TRACKS UP THE MIDDLE ATLANTIC COAST ON SATURDAY. STILL SOME TIMING
ISSUES WITH THIS STORM AND WITH VARIABILITY AMONGST THE MODELS AS TO
THE STRENGTH AND DEPTH OF THE LOW, DIDN'T WANT TO GET CUTESY WITH
THE WEATHER GRIDS. STUCK WITH A RAIN/SNOW FORECAST FOR NOW. BASED ON
THE LATEST MODEL GUIDANCE, THE BEST CHANCES FOR MEASURABLE
PRECIPITATION TO FALL LOOKS TO BE THROUGH THE I-95 CORRIDOR, SOUTH
AND EAST. HOWEVER, MODEL CONSENSUS CONTINUES TO INDICATE THAT WE
WILL SEE SNOW THROUGH OUR ENTIRE FORECAST AREA THROUGH EARLY SUNDAY
AND WE HAVE INCREASED THE POPS TO LIKELY ACROSS THE AREA. ANY
LINGERING SNOW SHOWERS SHOULD TAPER OFF ON SUNDAY AS THE SYSTEM
MOVES OFF TOWARDS THE CANADIAN MARITIMES.
HIGH PRESSURE THEN BUILDS IN FOR SUNDAY AND MONDAY WITH A COLD FRONT
EXPECTED TO MOVE ACROSS THE REGION MONDAY NIGHT OR TUESDAY.
&&
.AVIATION /00Z THURSDAY THROUGH MONDAY/...
THE FOLLOWING DISCUSSION IS FOR KPHL, KPNE, KTTN, KABE, KRDG, KILG,
KMIV, KACY AND SURROUNDING AREAS.
WITH THE LATEST 00Z TAFS, KABE WILL HAVE FREEZING RAIN INTO THIS
EVENING BEFORE WE CHANGE THEM OVER TO RAIN. ALL OTHER TAF SITES
JUST RAIN.
DURING THIS EVENING THE LAST BAND OF HEAVIER RAIN WILL MOVE
THROUGH WITH CIGS ALONG THE MVFR AND IFR THRESHOLD AND VSBYS
DROPPING TO IFR WHEN THE HEAVIER RAIN MOVES THRU. LLWS WILL BE
CONTINUED AS A LLJ WILL AVERAGE AROUND 60KTS FROM THE E OR SE.
OVERNIGHT LIGHTER RAIN IS FORECAST WITH CIGS REMAINING NEAR THE
MVFR AND IFR THRESHOLD, BUT PREVAILING VSBYS SHOULD BE MVFR. WINDS
ARE FORECAST TO SLOWLY BACK TO THE NORTH AND NORTHWEST WITH LESS
GUSTINESS AS THE LLJ LIFTS TO THE NORTHEAST.
RAIN SHOULD END ON THURSDAY MORNING AS VSBYS BECOME VFR. CIGS
SHOULD AVERAGE MVFR AND SLOWLY IMPROVE TO VFR BY AFTERNOON.
NORTHWEST WINDS WILL START INCREASING WITH GUSTINESS LIKELY
BETWEEN 20 AND 30 KTS.
ON THURSDAY AFTERNOON, VFR CIGS ARE FORECAST AND WINDS SHOULD ALSO
INCREASE FROM THE NORTHWEST WITH SUSTAINED SPEEDS CLOSE TO 20 KTS
AND PEAK GUSTS EXCEEDING 30 KTS.
OUTLOOK...
THURSDAY NIGHT THROUGH FRIDAY...VFR CONDITIONS EXPECTED. NORTHWEST
WINDS 15-25 KNOTS WITH GUSTS 30-35 KNOTS THURSDAY NIGHT, DIMINISHING
TO 10-20 KNOTS ON FRIDAY. WINDS WILL DIMINISH FURTHER FRIDAY
EVENING.
SATURDAY...VFR CONDITIONS EXPECTED AT THE START OF THE DAY WITH
SUB-VFR CONDITIONS EXPECTED THROUGH THE AFTERNOON AND EVENING.
TIMING REMAINS AN ISSUE WITH RESPECT TO PRECIPITATION AND STRENGTH
OF THE WINDS. SNOW IS EXPECTED TO FALL ACROSS THE REGION AND AFFECT
THE TERMINALS.
SUNDAY AND MONDAY...MAINLY VFR CONDITIONS EXPECTED. SOME FLURRIES OR
SNOW SHOWERS MAY AFFECT THE NORTHWESTERN TERMINALS /KABE TO KRDG/ ON
SUNDAY. NORTHWEST WINDS 15-20 KNOTS WITH GUSTS AROUND 30 KNOTS CAN
BE EXPECTED ON SUNDAY...BECOMING MORE WESTERLY 10-15 KNOTS ON MONDAY.
&&
.MARINE...
WE HAVE EXTENDED THE GALE WARNING THROUGH THURSDAY OVER THE SOUTHERN
ATLANTIC WATERS AND DELAWARE BAY, AND WE HAVE MAINTAINED THE STORM
WARNING OVER THE NORTHERN ATLANTIC WATERS THROUGH 6 AM EST THURSDAY.
IT MAY BE DOWNGRADED TO A GALE WARNING BEFORE THEN. THE LOW LEVEL
JET IS QUITE ROBUST THROUGH THE EVENING (ESPECIALLY NORTHEAST), AND
IT RUNS IN EXCESS OF 35 KNOTS IN THE COLD AIR ADVECTION ON THURSDAY.
THERE MAY BE A LULL IN THE JET AND THE SURFACE WINDS OVERNIGHT
TONIGHT. SEAS TONIGHT IN EXCESS OF 15 FEET ARE POSSIBLE IN THE STORM
WARNING REGION. THEY WILL APPROACH 15 FEET OVER THE SOUTHERN
ATLANTIC WATERS TONIGHT, AND ALL ATLANTIC SEAS WILL SUBSIDE A BIT
THROUGH THURSDAY. SEAS OVER THE BAY GENERALLY WILL RANGE FROM 3 TO 6
FEET.
OUTLOOK...
GALE FORCE GUSTS WILL START TO DIMINISH THURSDAY EVENING AND BECOME
SMALL CRAFT CONDITIONS ON FRIDAY. BOTH WINDS AND SEAS WILL DECREASE
THROUGH THE DAY ON FRIDAY AND FALL BELOW SMALL CRAFT ADVISORY LEVELS
BY FRIDAY AFTERNOON AS THE PRESSURE GRADIENT WEAKENS ACROSS THE
REGION.
HIGH PRESSURE WILL BUILD ACROSS THE AREA ON FRIDAY AND KEEP US
HEADLINE FREE THROUGH MOST OF SATURDAY. A COASTAL STORM IS SLATED TO
ARRIVE OVER THE WEEKEND, IMPACTING THE AREA WATERS STARTING SATURDAY
EVENING. WITH DISAGREEMENT AMONGST THE MODEL GUIDANCE AS TO THE
STRENGTH AND TRACK OF THE SYSTEM, THE DETAILS REMAIN A LITTLE FUZZY.
EXPECT AND INCREASE IN WINDS AND SEAS AS THE SYSTEM APPROACHES AND
AT LEAST SMALL CRAFT ADVISORIES LOOK LIKE THEY WILL BE NEEDED. A
PERIOD OF GALE FORCE GUSTS ALSO LOOKS POSSIBLE FOR A PERIOD OF TIME
ON SUNDAY. BOTH WINDS AND WAVES WILL GRADUALLY DIMINISH BEHIND THIS
SYSTEM BUT A DECENT PRESSURE GRADIENT LOOKS TO REMAIN ACROSS THE
AREA AND SMALL CRAFT ADVISORY LEVEL WINDS MAY REMAIN ON THE OPEN
WATERS THROUGH AT LEAST MONDAY.
&&
.HYDROLOGY...
MODELS HAVE FAIRLY CONSISTENTLY SHOWN ABOUT 1.25 TO 2.25 INCHES OF
LIQUID OVER THE WATCH AREA, AND THE HEADWATER GUIDANCE AND THE
HIGHER END OF THE AFOREMENTIONED QPF SUPPORT MAINTAINING THE WATCH.
THE RIVER FORECAST CENTER HAS INDICATED THAT FLOODING MAY BE
CONFINED TO STREAMS AND THE SMALLER RIVERS.
&&
.TIDES/COASTAL FLOODING...
COASTAL FLOOD WARNING WAS ISSUED AROUND RARITAN BAY AND MONMOUTH
COUNTY FOR THE MORNING HIGH TIDE. A COASTAL FLOOD ADVY WAS ISSUED
FOR OCEAN COUNTY FOR THE SAME HIGH TIDE. WE HAVE ALSO ISSUED A
COASTAL FLOOD ADVISORY FOR HYBRID FLOODING, TIDES AND HEAVY RAIN
RUNOFF IN THE TIDAL DELAWARE RIVER FOR THE OVERNIGHT HIGH TIDE CYCLE.
THINKING IS PLACES FARTHER TO THE SOUTH ARE NOT GOING TO HAVE ENOUGH
TIME TO RAMP UP WITH THE LOWER ASTRONOMICAL HIGH TIDE THIS
EVENING. ACY'S TIDE IS ABOUT TO CREST NEAR THE MINOR TIDAL
FLOODING THRESHOLD OF 6.0 FEET ABV MLLW. TIDAL DEPARTURES ARE CURRENTLY
1.5 FEET AND WE WOULD NEED A DOUBLING IN LESS THAN THREE HOURS.
THEN FOR THE NEXT, THURSDAY MORNING HIGH TIDE CYCLE THE WINDS WILL
BE BLOWING OFFSHORE. THERE HAS TO BE A PIVOT POINT IN ALL OF THIS
ALONG THE NEW JERSEY COAST WHICH FOR NOW WE HAVE THE BEST
CONFIDENCE IN OCEAN COUNTY.
AS FOR CHESAPEAKE BAY, TIDAL DEPARTURES ARE AROUND HALF A FOOT.
CBOFS IS CURRENTLY RUNNING TO HIGH WITH THE APPROACHING HIGH TIDE
CYCLE AND IT JUST TOOK CAMBRIDGE TO OUR MINOR TIDAL FLOODING
PRODUCT ISSUANCE LEVEL. THE GUIDANCE DOES THE SAME WITH THE NEXT
HIGH TIDE CYCLE AT TOLCHESTER BEACH ON THURSDAY MORNING, BUT BY
THEN THE BAY SHOULD START DRAINING, SO PREFER TO SEE HOW THE TIDES
TRANSPIRE OVERNIGHT AND JUST LEAVE THE CHANCE IN THE HWO.
