What happened

The episode as NWS PHI wrote it up.

Strong to high winds occurred in the wake of the departing winter storm low pressure system on the 27th across Eastern Pennsylvania. Peak wind gusts average 50 to 55 mph and knocked down some weak tree limbs and power lines. The largest effect though was the considerable blowing and drifting of the snow the wind caused. This hampered plowing and clean-up operations after the snow ended. Sporadic power outages were reported in the local Philadelphia area.

The winds were caused first by pressure gradient (difference) between the low pressure system and a strong high pressure building east from the central part of the United States. Winds eased as the low moved farther away from the Middle Atlantic States as the day progressed on the 27th as well as it stopped intensifying after the morning of the 27th. The low pressure system's surface pressure bottomed at 961 millibars at 10 a.m. EST on the 27th as it was passing just east of Cape Cod, Massachusetts.

What forecasters said that day

The local office's own words before the first event, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.

NWS Philadelphia/Mount Holly wrote its last area forecast discussion before the first event at Dec 26, 11:45 PM EST, 15 minutes earlier.

Area forecast discussion, Dec 26, 11:45 PM EST, 15 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MOUNT HOLLY NJ
1145 PM EST SUN DEC 26 2010

.SYNOPSIS...
LOW PRESSURE OFF THE MID-ATLANTIC COAST WILL CONTINUE TO INTENSIFY
AS IT MOVES NORTHEAST TO A POSITION OFF THE NEW ENGLAND COAST ON
MONDAY. HIGH PRESSURE IS THEN EXPECTED TO BUILD ACROSS THE REGION
AND DOMINATE THE WEATHER PATTERN FOR MOST OF THE WEEK. A COLD
FRONT MAY CROSS THE AREA LATE IN THE UPCOMING WEEKEND.

&&

.NEAR TERM /UNTIL 6 AM MONDAY MORNING/...
OUR HUNCH IS THAT WE SHOULD DROP THE WARNINGS FOR THE MARYLAND
EASTERN SHORE, ALL OF DELAWARE, BERKS, CHESTER AND CARBON
COUNTIES. HOWEVER, MODEL GUIDANCE STILL SUPPORTS SOME
REDEVELOPMENT OVERNIGHT, AND SO WE ARE REMAINING CAUTIOUS FOR NOW.

SOME BANDING STILL IS GOING ON OVER THE NORTHEASTERN PART OF OUR
FORECAST AREA AND FROM NEAR PHILADELPHIA TO NEAR CAPE MAY. THE
FORMER BAND IS LINING UP NICELY WITH LOWER LEVEL FRONTOGENESIS
FIELDS, WHILE THE LATTER IS A BIT DISPLACED TO THE NORTHEAST.
FRONTOGENESIS PROGS HAVE THE BANDS WEAKENING WITH TIME OVERNIGHT.

THE WIND CONTINUES AS THE SURFACE LOW OFF THE NORTHERN NEW JERSEY
COASTLINE IS IN THE PROCESS OF STACKING UP TO H5. THE END OF BLIZZARD
CONDITIONS LOOK TO BE A FUNCTION OF WHEN THE BANDING ENDS. WINDS
SHOULD CONTINUE TO GUST ABOVE 35 MPH IN THE WARNING AREA, ALTHOUGH
THEY SHOULD RELAX A BIT.

THE ENDING TIME OF THE WARNINGS WAS CUT AS THE MAIN IMPACT SHOULD
END AFTER THE SNOW TAPERS OFF. WHILE BLOWING AND DRIFTING MAY
CONTINUE MONDAY MORNING...THE WARNINGS WERE SHAVED BACK TO FOCUS
ON THE HEART OF THE EVENT OVERNIGHT.

&&

.SHORT TERM /6 AM MONDAY MORNING THROUGH WEDNESDAY/...
ANY LINGERING SNOW WILL END FROM SOUTH TO NORTH DURING THE MORNING
HOURS. THE WIND WILL CONTINUE TO HOWL FROM THE NORTHWEST THROUGH
THE DAY...BUT NOT QUITE AS STRONG AS DURING THE OVERNIGHT HOURS.
THEN AS THE SUN SETS LATE MONDAY AFTERNOON...THEY WILL SUBSIDE.
WITH A SNOW COVER AND CLEAR SKIES...TEMPERATURES SHOULD DROP LIKE
A ROCK MONDAY NIGHT. COLD BUT TRANQUIL CONDITIONS ARE EXPECTED FOR
BOTH TUESDAY AND WEDNESDAY.

&&

.LONG TERM /WEDNESDAY NIGHT THROUGH SUNDAY/...
AFTER A PERIOD OF LESS AMPLIFIED FLOW ALOFT DURING THE MIDDLE OF THE
UPCOMING WEEK...THE PATTERN WILL AGAIN AMPLIFY ACROSS NORTH AMERICA.
THE DIFFERENCE THIS TIME IS THAT UNLIKE THE PAST MONTH...WE WILL
BEGIN ON THE WARMER SIDE OF THE CHANGE THIS TIME. THIS WILL MEAN
ABOVE NORMAL TEMPERATURES BY THIS TIME NEXT WEEK AND MORE RAIN THAN
SNOW WHEN A DISTURBANCE MOVES BY.

MUCH OF THE EXTENDED PERIOD WILL FEATURE DRY WEATHER AS HIGH
PRESSURE WILL REMAIN ACROSS THE EAST COAST FROM WEDNESDAY NIGHT
THROUGH SATURDAY. AN UPPER RIDGE WILL BE BUILDING ON TOP OF THE SFC
HIGH...SO TEMPERATURES WILL BECOME MILDER AS THE WEEK PROGRESSES.
THE MILDER TEMPERATURES WILL BE REFLECTED IN THE HIGH TEMPERATURES
MORE THAN THE LOWS...SINCE THE CLR TO PARTLY CLOUDY SKIES WILL ALLOW
FOR DECENT NIGHTTIME COOLING...ESPECIALLY OVER ANY SNOW COVER. HIGHS
THU WILL BE SLIGHTLY BELOW NORMAL. HIGHS WILL THEN BE NEAR NORMAL
FRI AND ABOVE NORMAL SAT AND SUN. HIGH IN THE MID 40S TO NEAR 50 MAY
OCCUR BY SUN.

THE STORM TO WATCH DURING THE EXTENDED PERIOD WILL BE WELL WEST OF
OUR AREA. IT WILL DEEPEN OVER THE PLAINS STATES FRI AND THEN MOVE UP
INTO CANADA NEXT WEEKEND. IT WILL CAUSE A SFC COLD FRONT TO APPROACH
FROM THE WEST SAT INTO SUN. FOR THIS REASON...AND ALIGNING WITH THE
HPC...WE HAVE INCLUDED CHC OR SLGT CHC POPS FOR SAT INTO SUN.
TEMPERATURES WILL PROBABLY FALL BACK TO NEAR NORMAL BEHIND THE FRONT
FOR THE FIRST FULL WEEK OF THE NEW YEAR.

&&

.AVIATION /06Z MONDAY THROUGH FRIDAY/...
A MAJOR WINTER STORM WILL CONTINUE TO AFFECT THE TAF SITES THIS
AFTERNOON INTO TONIGHT.

IFR CONDITIONS DUE TO HEAVY SNOW HAVE OVERSPREAD THE TAF SITES AND
THESE CONDITIONS WILL CONTINUE THROUGH MIDNIGHT TONIGHT.  WINDS WILL
INCREASE DURING THE EVENING HOURS RESULTING IN AN INCREASE OF
BLOWING SNOW.

THE MAIN ACCUMULATING SNOW WILL BE CONCLUDED BY 06Z-08Z TIMEFRAME.
HOWEVER BLOWING SNOW WILL CONTINUE INTO THE DAY ON MONDAY.

CONDITIONS SHOULD IMPROVE TO MVFR BY 10-12Z MONDAY WITH VFR
CONDITIONS EXPECTED BY LATE MORNING...UNLESS VISIBILITIES ARE REDUCED
ENOUGH DUE TO BLOWING SNOW.

OUTLOOK...
HIGH PRESSURE WILL BUILD INTO OUR REGION FROM THE WEST AND DOMINATE
OUR WEATHER TUESDAY THROUGH THURSDAY.

&&

.MARINE...
A MAJOR WINTER STORM WILL CONTINUE TO AFFECT THE COASTAL WATERS
TONIGHT INTO MONDAY.

LATEST GUIDANCE CONTINUES TO SUPPORT STORM WARNING IN COASTAL WATERS
FROM LITTLE EGG INLET NORTHWARD WITH MAXIMUM WINDS OF 55 KNOTS
EXPECTED. CONTINUED STORM WARNING THROUGH 23Z MONDAY...AS WIND GUSTS
WILL CONTINUE TO BE STRONGER OVER OUR NORTHERN WATERS...AND GUSTS
MAY STILL REACH 50 KNOTS MONDAY.

ELSEWHERE THE GALE WARNING WILL CONTINUE AS IS....IN EFFECT THROUGH
12Z TUESDAY FOR NOW.

WAVE HEIGHTS ON OUR OCEAN WATERS ARE EXPECTED TO REACH 10 TO 13 FT
AT THE HEIGHT OF THE STORM LATE TODAY INTO TONIGHT...THEN GRADUALLY
LOWER AND DROP BELOW ADVISORY CRITERIA TUESDAY AFTERNOON. BUMPED
SEAS TONIGHT & MONDAY ABOVE WAVEWATCH BASED ON OBSERVED CONDITIONS.

HIGH PRESSURE WILL PUSH IN FROM THE WEST TUESDAY AND DOMINATE OUR
WEATHER THROUGH THURSDAY. WEST TO NORTHWEST WINDS WILL CONTINUE TO
GUST TO OVER 25 KNOTS THROUGH TUESDAY, BUT MAY DROP BELOW ADVISORY
CRITERIA TUESDAY NIGHT.  SUB-ADVISORY WINDS AND SEAS ARE FORECAST
FOR WEDNESDAY THROUGH FRIDAY.

&&

.TIDES/COASTAL FLOODING...
COASTAL FLOOD WARNING CONTINUES FROM 02Z THROUGH 09Z TONIGHT FOR THE
OCEAN FRONT AND BACK BAYS FOR OCEAN AND MONMOUTH COUNTIES...AND ALSO
FOR THE BAYFRONT IN MIDDLESEX...FOR MINOR TO AREAS OF MODERATE TIDAL
FLOODING. CONFIDENCE IS GOOD THAT WE WILL REACH MODERATE FLOODING
LEVELS.

HAVE EXTENDED THE COASTAL FLOOD WARNING SOUTHWARD TO INCLUDE
SOUTHEAST BURLINGTON AND ATLANTIC COUNTY AS LATEST OBSERVATIONS &
GUIDANCE SUPPORT THEM REACHING MODERATE COASTAL FLOODING CRITERIA ON
THE UPCOMING HIGH TIDE.

FURTHER SOUTH...POSITIVE ANOMALIES ARE NOT EXPECTED TO BE AS HIGH
AS WINDS WILL NOT BE AS STRONG. EVEN SO...ANOMALIES OF PLUS 2 FEET
ARE LIKELY TO CAUSE MINOR TIDAL FLOODING...SO A COASTAL FLOOD
ADVISORY CONTINUES FOR THE HIGH TIDE CYCLE TONIGHT.

ADDITIONAL TIDAL FLOODING AFTER TONIGHT/S HIGH TIDE CYCLE IS LESS
LIKELY...AS THE OFFSHORE WIND FLOW WILL ALLOW DEPARTURES TO
LOWER...ALTHOUGH WATER LEVELS WILL REMAIN HIGH.
