The episode as NWS PHI wrote it up.
The same low pressure system that brought strong winds to Delaware on the 27th, brought additional strong west to northwest winds to the state during the daytime on the 28th. Peak wind gusts averaged around 45 mph and brought down additional tree limbs and weak trees. Peak wind gusts included 47 mph in Lewes (Sussex County) and 45 mph at the New Castle County Airport. The second round of strong winds was caused by the strong sea level pressure difference between the departing but intensifying low pressure system as it moved northeast along the Saint Lawrence River Valley and a high pressure system building east from the Great Lakes. Once the high pressure system moved closer, the strong winds subsided late in the afternoon.

NWS Philadelphia/Mount Holly wrote its last area forecast discussion before the first event at Dec 28, 3:00 AM EST, 6 hours earlier.
AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MOUNT HOLLY NJ
300 AM EST WED DEC 28 2011
.SYNOPSIS...
INTENSIFYING LOW PRESSURE WILL MOVE NORTHEASTWARD THROUGH THE
SAINT LAWRENCE VALLEY TODAY AND INTO THE CANADIAN MARITIMES
TONIGHT AND THURSDAY. HIGH PRESSURE WILL BUILD TO OUR SOUTH THIS
AFTERNOON INTO THURSDAY. A SERIES OF LOW PRESSURE SYSTEMS AND
FRONTAL BOUNDARIES WILL MOVE ACROSS THE NORTHERN TIER OF THE
COUNTRY THROUGH MONDAY. A CANADIAN HIGH PRESSURE SYSTEM WILL START
BUILDING INTO THE EASTERN UNITED STATES TUESDAY.
&&
.NEAR TERM /THROUGH TODAY/...
THE MAIN FORECAST PROBLEM TODAY WILL BE THE WIND.
OTHER THAN A FEW PATCHES OF STRATOCUMULUS ACROSS DELAWARE AND
SOUTHERN NEW JERSEY...AS WELL AS THE HIGHER TERRAIN...CLOUDS HAVE
CLEARED OUT. THERE ARE SOME SPRINKLES IN THE LEHIGH VALLEY AND THE
SOUTHERN POCONOS...BUT MOST OF THIS IS FAIRLY LIGHT. THE SPRINKLES
COULD BECOME FLURRIES IN THE SOUTHERN POCONOS AND NORTHWEST NEW
JERSEY BEFORE DAYBREAK AS COLD AIR ADVECTION COMMENCES.
WINDS ARE STARTING TO PICK UP AGAIN IN THE HIGHER TERRAIN AS THE
COLD AIR ADVECTION KICKS IN. WIND GUSTS TO 30 KNOTS HAVE BEEN
NOTED IN CENTRAL AND WESTERN PENNSYLVANIA...AND THESE TYPE OF
GUSTS ARE POSSIBLE IN THE LEHIGH VALLEY AND HIGHER TERRAIN BEFORE
SUNRISE.
THE GRADIENT WILL CONTINUE TO TIGHTEN THIS MORNING...SO THAT ABOUT
AN HOUR OR SO AFTER SUNRISE...THE GRADIENT WIND WILL INCREASE IN
ALL AREAS. THE GRADIENT LOOKS TO SUPPORT SUSTAINED WIND BETWEEN 15
AND 25 MPH...WITH THE GRADIENT TIGHTENING ONCE MORE IN THE LATE
AFTERNOON AND EVENING...AS ANOTHER SHOT OF COLD AIR ADVECTION
ARRIVES.
MODEL SOUNDINGS SUGGEST 35 TO 40 KNOTS OF WIND WILL BE AVAILABLE
AT THE TOP OF THE INVERSION THIS MORNING...DURING THE BEST OF THE
COLD AIR ADVECTION. THESE WINDS WOULD TRANSLATE TO 35 TO 40 MPH
GUSTS...AND PERHAPS A BIT HIGHER IN THE SOUTHERN POCONOS AND
NORTHWEST NEW JERSEY. A LAST PUSH OF COLD AIR ADVECTION WILL OCCUR
DURING THE LATE AFTERNOON AND EARLY EVENING...AND MODEL SOUNDINGS
SHOW ABOUT 40 KNOTS AT THE TOP OF THE INVERSION.
THIS ALSO MEANS 35 TO 40 MPH WIND GUSTS...SO RIGHT NOW NO WIND
HEADLINES ARE PLANNED FOR TODAY. THE 40 MPH WIND GUSTS WILL BE
MENTIONED IN THE GRIDDED AND TEXT FORECASTS...AS WELL AS THE
HAZARDOUS WEATHER OUTLOOK. ANY INCREASE IN THE EXPECTED WIND
SPEEDS COULD RESULT IN THE ISSUANCE OF A SHORT FUSED WIND ADVISORY
LATER THIS MORNING.
THE CLOUDINESS OVER THE HIGHER TERRAIN AND NORTHERN LEHIGH VALLEY
MAY BE TOUGH TO DISLODGE TODAY...AS COLD AIR ADVECTION LOWERS THE
CONVECTIVE TEMPERATURES. UPSTREAM CONVECTIVE TEMPERATURES ARE
WITHIN REACH...SO THESE AREAS MAY STAY MOSTLY CLOUDY TODAY. THE
PASSAGE OF THE LONG WAVE TROUGH LATE THIS MORNING AND EARLY THIS
AFTERNOON COULD BRING SCATTERED SNOW SHOWERS TO THE HIGHER TERRAIN
AND PERHAPS SOME FLURRIES TO THE LEHIGH VALLEY AND NORTHERN NEW
JERSEY. WHILE MID LEVEL LAPSE RATES STEEPEN WITH THE PASSAGE OF
THE LONG WAVE TROUGH...MOISTURE WILL BECOME INCREASINGLY
SPARSE...SO SPRINKLES OR FLURRIES WILL NOT BE PLACED IN THE
FORECAST ELSEWHERE.
THE PASSAGE OF THE MID LEVEL TROUGH AND LOWERING OF THE CONVECTIVE
TEMPERATURES SHOULD ALLOW FOR A FAIR AMOUNT OF CUMULUS AND
STRATOCUMULUS TO DEVELOP IN THE COLD AIR ADVECTION. THIS IS
REFLECTED IN THE STATISTICAL GUIDANCE AS WELL..SO PARTLY TO MOSTLY
SUNNY SKIES SHOULD SUFFICE.
GUIDANCE IS SUGGESTING FALLING TEMPERATURES TODAY (ESPECIALLY THE
NAM MOS GUIDANCE). WHILE THIS IS POSSIBLE IN THE SOUTHERN POCONOS
AND NORTHWEST NEW JERSEY...ELSEWHERE...THE COLD AIR ADVECTION DOES
NOT SEEM STRONG ENOUGH FOR THIS TO OCCUR. THEREFORE...HIGHS TODAY
WILL BE BASED MAINLY ON THE GFS MOS...WHICH SHOULD A DROP THIS
MORNING...THEN A SMALL RISE IN TEMPERATURES THIS AFTERNOON.
&&
.SHORT TERM /TONIGHT/...
AS THE LAST THRUST OF COLD AIR ADVECTION EXITS THE AREA IN THE
EVENING...THERE WILL BE ANOTHER PUSH OF WIND GUSTS. AGAIN...
FOLLOWING THE REASON OUTLINED IN THE NEAR TERM SECTION...WILL HOLD
OFF ON ANY WIND HEADLINES. THE LATE ARRIVAL OF THE PUSH...WHICH
MEANS NO HEATING TO HELP MOMENTUM TRANSFER EFFICIENCY...PROBABLY
KEEPS GUSTS UNDER 45 MPH.
THE LAST OF THE STRATOCUMULUS SHOULD BE HOLED UP IN THE HIGHER
TERRAIN...AS WHAT MOISTURE REMAINS GETS TRAPPED UNDER THE NEW
INVERSION. THE LOWER CLOUDS SHOULD BE ABLE TO EXIT BY LATE
EVENING...AS THE COLD AIR ADVECTION ENDS. HOWEVER...MID LEVEL
CLOUDINESS WILL APPROACH FROM THE SOUTHWEST...AS WARM AIR
ADVECTION COMMENCES IN THE MID LEVELS. SO...OVERALL SKIES SHOULD
BE PARTLY CLOUDY.
SUSTAINED WINDS PROBABLY STAY UP MOST OF THE NIGHT...WHICH MEANS
THE AIRMASS SHOULD BE FAIRLY WELL MIXED. THE MOS NUMBERS ARE CLOSE
(AS THEY USUALLY ARE IN WELL MIXED ENVIRONMENTS) AND ARE ACCEPTED
FOR LOWS.
&&
.LONG TERM /THURSDAY THROUGH TUESDAY/...
OVERALL LOWER THAN AVERAGE CONFIDENCE EXISTS FOR THE LONG TERM
FORECAST. BUT, CONFIDENCE HAS GOTTEN A LITTLE HIGHER FOR THE FIRST
COUPLE OF PERIODS AS THE 00Z GFS AND THE 00Z ECMWF ARE A LITTLE
CLOSER IN STORM TRACK AND TIMING.
THE LONG TERM PERIOD WILL BEGIN QUIETLY THURSDAY WITH HIGH
PRESSURE RIDGING UP FROM THE SOUTH. CLOUDS ARE FORECAST TO
INCREASE DURING THURSDAY AS WARM AIR ADVECTION BEGINS IN ADVANCE
OF THE NEXT WEATHER SYSTEM. SLIGHT CHANCE PROBABILITIES FOR SNOW
SHOWERS WERE KEPT FOR THE FAR NORTHERN ZONES THURSDAY AFTERNOON.
OTHERWISE, FOR THURSDAY NIGHT LOW CHANCE PROBABILITIES WERE
RETAINED FOR THE NORTHERN PART OF THE AREA. THE FORECAST QVEC
CONVERGENCE IS PRETTY DECENT, BUT THE OVERALL FORECAST ISENTROPIC
LIFT, ESPECIALLY ONCE WE GET ABOVE 800MB IS FAIRLY NEGLIGIBLE, NOT
THE BEST OF SIGNS IN THE WARM AIR ADVECTION PART OF THE SYSTEM.
THE INCREASING LOW LEVEL JET DURING THURSDAY NIGHT BRINGS IN THE
POSSIBILITY OF SOME NON-SNOW PRECIPITATION TYPES NORTH, ESPECIALLY
OFF THE WRF-NMM. IT WAS DECIDED TO USE THE COLDER ECMWF SOLUTION
AND KEEP THE PRECIPITATION TYPE EITHER SNOW OR RAIN. BOWING TO THE
FORECAST INCREASING SOUTHWEST FLOW AND THE INCREASING 925MB JET,
WE PLACED LOWS EARLIER IN THE NIGHT IN THE GRIDS AND RAISED
TEMPERATURES TOWARD MORNING. MODEL QPF AMOUNTS REMAIN MODEST AND
IT IS SUSPECTED THAT IF SNOW WERE TO FALL, ACCUMULATIONS WOULD BE
AT SUB-ADVISORY LEVELS.
CONTINUING WITH THE PREMISE THAT THE GFS MAY BE TOO FAST, THE
SECOND SHOT OF MOISTURE COMING FROM THE SYSTEM IN ALBERTA WAS
PROJECTED MORE IN THE FRIDAY AND FRIDAY NIGHT PART OF THE
FORECAST. OUR AREA SHOULD THEN HAVE A LULL SATURDAY INTO SUNDAY.
THE GREATER CONFIDENCE FOR PRECIPITATION IS FOR SATURDAY NIGHT,
WHEN MOST MODELS ARE IN AGREEMENT. THIS WOULD BE CONVENIENT IF
TRUE, SINCE IT IS NEW YEARS EVE.
THE NEXT PRECIPITATION CHANCE WOULD OCCUR WITH THE NEXT COLD
FRONTAL PASSAGE, EXPECTED SUNDAY NIGHT OR MONDAY. BY THEN THE
MODEL SPREAD IS GETTING FAIRLY LARGE AND OUR PRECIPITATION TIMING
SHOULD BE VIEWED AS LESS THAN AVERAGE. IT MIGHT BE COLD ENOUGH FOR
SOME SNOW NORTH, WHILE MAINLY RAIN IS EXPECTED SOUTH BASED ON THE
CURRENT TRACK OF THE SURFACE LOW AND FORECAST THERMAL FIELDS.
THE BIGGER DIFFERENCE OCCURS ON TUESDAY AS THE OPERATIONAL ECMWF
SHARPENS THE UPPER TROUGH AND SLOWS THE PROGRESSION OF THE COLD
FRONT OFFSHORE, PERMITTING A LOW TO RIDE UP THE COAST. THE GFS AND
UKMET CONTINUE FAIRLY PROGRESSIVE, AND THE HPC SOLUTION WAS
FOLLOWED WITH A MORE PROGRESSIVE SOLUTION SO AS TO KEEP TUESDAY
DRY.
FROM FRIDAY THROUGH THE END OF THE FORECAST PERIOD DUE TO THE
HIGHER THAN AVERAGE UNCERTAINTIES, WE DID ABOUT A ONE-THIRD BLEND
OF CONTINUITY, HPC GUIDANCE, AND MEX MOS FOR MAX AND MIN TEMPS.
&&
.AVIATION /08Z WEDNESDAY THROUGH SUNDAY/...
THE FOLLOWING DISCUSSION IS FOR KPHL, KPNE, KTTN, KABE, KRDG,
KILG, KMIV, KACY AND SURROUNDING AREAS.
CONDITIONS ARE GENERALLY VFR EARLY THIS MORNING...AS THE CLOUDS
ASSOCIATED WITH THE FRONT HAS MOVED EAST. THERE IS SOME MOISTURE
TRAPPED UNDER THE INVERSION LEFT BEHIND THE FRONT...AND THE
MOISTURE APPEARS TO BE LINGERING NEAR 3000 FEET. BECAUSE OF
THIS...MVFR CEILINGS WERE MENTIONED FOR KRDG AND KABE THROUGH
ABOUT 0900 UTC. IT YET REMAINS TO BE SEEN IF THE MOISTURE LINGERS
AFTER THAT TIME...AS MODEL SOUNDINGS SUGGEST THE THREAT CONTINUES
THROUGH ABOUT 1200 UTC.
ELSEWHERE...VFR CONDITIONS ARE EXPECTED THROUGH 1200 UTC...WITH
JUST SOME STRATOCUMULUS IN THE FLOW. FOR THE MOST PART...WINDS
HAVE DROPPED TO BELOW 10 KNOTS IN THE SLACK GRADIENT BETWEEN THE
FRONT THAT MOVED OFFSHORE...AND HIGH PRESSURE TO THE WEST. THERE
ARE GUSTS ACROSS CENTRAL AND WESTERN PENNSYLVANIA...AS THE
GRADIENT TIGHTENS THERE FIRST. FOR NOW...GUSTS WERE NOT INCLUDED
IN MOST 0600 UTC FORECASTS THROUGH 1200 UTC...BUT THE POTENTIAL IS
BEING MONITORED.
THE MAIN PROBLEM TODAY WILL BE THE WIND. THE GRADIENT WILL SUPPORT
SUSTAINED WINDS BETWEEN 15 AND 24 KNOTS AT ALL TERMINALS...WITH
THE HIGHEST SUSTAINED WINDS AT THE KPHL METRO AIRPORTS. MODEL
SOUNDINGS SHOW 35 TO 40 KNOTS OF WINDS AT THE TOP OF THE
INVERSION. THIS SHOULD TRANSLATE TO 28 TO 35 KNOT WIND
GUSTS...AGAIN WITH THE HIGHEST GUSTS AT THE KPHL METRO AIRPORTS.
A MID LEVEL TROUGH WILL CROSS THE REGION AROUND 1500 UTC. THIS
WILL LOWER CONVECTIVE TEMPERATURES...AND VFR CEILINGS (BETWEEN
4500 AND 600 FEET) ARE EXPECTED BETWEEN 1500 UTC AND 2100
UTC...WITH THE EXCEPTION OF KMIV AND KACY. CLOUDS SHOULD START TO
THIN OUT AFTER 2100 UTC.
GUSTY WINDS WILL CONTINUE INTO THE EVENING HOURS...WITH VFR
CONDITIONS EXPECTED. MODEL SOUNDINGS SUGGEST GUSTINESS COULD
CONTINUE AT THE KPHL METRO AIRPORTS THROUGH ABOUT 0300 UTC. SOME
MID LEVEL CLOUDINESS IS EXPECTED AFTER 0600 UTC THURSDAY...AND
SHOULD CONTINUE THROUGH 1200 UTC THURSDAY.
OUTLOOK...
VFR CONDITIONS ARE EXPECTED THURSDAY. THEN, A SERIES OF FAST-
MOVING LOW PRESSURE SYSTEMS WILL BE AFFECTING OUR AREA FOR THE
REST OF THE OUTLOOK PERIOD. A GREATER IMPACT IS EXPECTED FOR THE
NORTHERN TAF SITES VERSUS THE SOUTHERN ONES, BUT BOTH COULD HAVE
PERIODS OF MARGINAL VFR CONDITIONS DURING PRECIPITATION. THE
NORTHERN SITES COULD BE AFFECTED MORE DUE TO THE POSSIBILITY OF
SNOW, AS WELL AS THE OVERALL GREATER CHANCE OF PRECIPITATION.
&&
.MARINE...
WINDS HAVE DROPPED BELOW SMALL CRAFT LEVELS ACROSS ALL WATERS
EARLY THIS MORNING...AS THE GRADIENT HAS SLACKENED CONSIDERABLY IN
THE WAKE OF THE COLD FRONT. HOWEVER...THE BREAK WILL ULTIMATELY BE
FAIRLY BRIEF...AS THE PRESSURE GRADIENT IS TIGHTENING AGAIN AS LOW
PRESSURE DEEPENS OVER NORTHERN NEW YORK STATE. WINDS WILL INCREASE
AGAIN TO SMALL CRAFT LEVELS BEFORE SUNRISE.
THE GRADIENT FLOW ITSELF APPEARS CAPABLE OF SUPPORT GALE FORCE
WINDS TODAY AS THE LOW DEEPENS IN EASTERN CANADA. MODEL SOUNDINGS
SHOW 35 TO 40 KNOTS OF WIND AT THE TOP OF THE INVERSION IN THE
BEST COLD AIR ADVECTION THIS MORNING...AND AGAIN LATE THIS
AFTERNOON AND EVENING. THE COLD AIR ADVECTION WILL HELP MOMENTUM
TRANSFER EFFICIENCY...AND A FEW GUSTS TO 40 KNOTS ARE
POSSIBLE...ESPECIALLY OVER THE OCEAN WATERS.
THE SECOND PUSH OF COLD AIR ADVECTION ARRIVES LATE THIS AFTERNOON
AND THIS EVENING. THIS MAY ENHANCE GUSTS FOR A TIME THIS
EVENING... SO THE GALE WARNINGS HAVE BEEN EXTENDED INTO THE
EVENING HOURS TO ACCOUNT FOR THE GUSTINESS. AFTER THAT...THE
GRADIENT FLOW SLOWLY WEAKENS...AND WINDS MAY BE ABLE TO DROP BELOW
SMALL CRAFT LEVELS LATE TONIGHT OR EARLY THURSDAY MORNING.
CONDITIONS WILL DROP BELOW SMALL CRAFT ADVISORY LEVELS BY THURSDAY
AS HIGH PRESSURE NEARS THE MARINE AREA. SMALL CRAFT CONDITIONS
MIGHT RETURN LATER THURSDAY NIGHT OR FRIDAY IN THE SOUTHWEST FLOW
PRECEDING THE NEXT COLD FRONT. A RELAXATION IN THE GRADIENT SHOULD
BRING WINDS AND SEAS BELOW SMALL CRAFT ADVISORY CRITERIA LATER
FRIDAY NIGHT INTO SATURDAY, BEFORE THE CHANCE FOR MORE SMALL CRAFT
ADVISORY CRITERIA PRECEDING THE NEXT COLD FRONT OCCURS SUNDAY.
