What happened

The episode as NWS OKX wrote it up.

A rapidly intensifying low pressure system tracked from off the Southeast US coast on Christmas Day and then past the Mid Atlantic Coast on Sunday December 26th to just east of Long Island by early Monday morning December 27th. This intense low pressure system spread snowfall into the region Sunday morning, with bands of heavy snow plus embedded thunderstorms and very strong winds affecting the region Sunday afternoon through Sunday night. The powerful blizzard (defined when sustained winds or frequent gusts greater than or equal to 35 mph accompanied by falling and/or blowing snow, frequently reducing visibility to less than 1/4 mile for three hours or more) brought a widespread area of 20 to 30 inches of snow across the NYC metro and Lower Hudson Valley, with 10 to 20 inches across Long Island. The heavy snow was accompanied by area wide winds of 25 to 40 mph and gusts in excess of 60 mph Sunday afternoon into Sunday night, resulting in near whiteout conditions with blowing and drifting snow and making all forms of travel extremely difficult to nearly impossible. In fact, all three major New York Airports were closed during and for a period after the storm. Bus service was severely hampered, and all service on the LIRR and several lines of MTA North, MTA subway, and PATH were suspended Sunday night into Monday morning due to high snow drifts. New York City struggled with snow removal due to the overwhelming blowing and drifting snow and stranded or abandoned buses and cars littering the streets, which severely hampered emergency services response times. In addition, 8000 customers lost power in New York City and Southern Westchester Counties, 8500 in Putnam and Northern Westchester, and 12,000 on Long Island during the height of the storm.

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE NEW YORK NY
934 AM EST SUN DEC 26 2010

.SYNOPSIS...
A DEVELOPING WINTER STORM OFF THE NORTH CAROLINA COAST WILL MOVE
NORTHEAST TO JUST SOUTH OF LONG ISLAND TONIGHT...BRINGING
BLIZZARD CONDITIONS TO MOST OF THE REGION. THE STORM WILL MOVE
INTO THE CANADIAN MARITIMES ON MONDAY. HIGH PRESSURE WILL RETURN
FOR THE MIDDLE OF THE WEEK.

&&

.NEAR TERM /UNTIL NOON TODAY/...
FIRST OF SEVERAL NEAR TERM MESOSCALE UPDATES FOR TODAY.
FIRST...SEEING SOME SPITS OF MAINLY LIGHT SNOW ACROSS EASTERN
LONG ISLAND AND COASTAL SE CT...DRIVEN IN PART BY LOW LEVEL
CONVERGENCE NOTED NEAR MONTAUK POINT WHERE A COASTAL FRONT MAY BE
DEVELOPING. HOW FAR WEST THAT COASTAL FRONT DRIVES TONIGHT AS THE
INTENSE LOW MAKES ITS CLOSEST APPROACH TO LONG ISLAND STILL A BIG
QUESTION...AS THE 12Z NAM...WHILE NOW VERY CLOSE TO THE 06Z
GFS/00Z ECMWF LOW TRACK...HANGS TOUGHER WITH COLDER AIR...WITH
ONLY BRIEF MIXING INDICATED NEAR MONTAUK AS MAX BL WET BULB TEMPS
WARM BRIEFLY ABOVE +1C TONIGHT. WET BULB TEMP JUST TO THE EAST AT
BLOCK ISLAND ALREADY WARM ENOUGH FOR RAIN...SO NAM TOO COLD
UNLESS STRONG NORTHERLY FLOW ON THE COLD SIDE LATER TODAY KEEPS
THE COASTAL FRONT IN PLACE.

OTHER BIG ISSUE CONCERNS EXACTLY WHERE HEAVIEST SNOW WILL FALL
LATER TODAY INTO TONIGHT...WHICH MAY BE COMING MORE INTO FOCUS.
THE 12Z NAM SHOWED ITS STRONGEST H7-8 LAYER FRONTOGENESIS
DISPLACED ABOUT 30 MILES NW OF THE STRONGEST RADAR RETURNS OFF
DELMARVA ATTM...NO SURPRISE THERE AS THIS OFTEN HAPPENS WITH
INTENSE COASTAL STORMS. TAKING THE NAM OTHERWISE AS A PERFECT PROG
AND FOLLOWING EVOLUTION OF ITS FRONTOGENETIC FORCING INDICATES
THAT THE HEAVIEST SNOW WILL OCCUR OVER SOUTH CENTRAL CT INTO
WESTERN SUFFOLK AND NASSAU COUNTIES ON LONG ISLAND..POSSIBLY A
LITTLE FARTHER WEST INTO SOUTHWEST CT AND NYC IF YOU LOOK AT H7
FRONTOGENESIS ONLY. MAY HAVE TO INCREASE MAX TOTALS IN THOSE AREAS
TO NEAR 20 INCHES...MAYBE MORE...AS THAT BANDING LOOKS TO SET UP
THERE TOWARD EVENING AND REMAIN FOR A GOOD CHUNK OF THE NIGHT.

&&

.SHORT TERM /NOON TODAY THROUGH TUESDAY/...
NO CHANGES TO THE WINTER STORM HEADLINES...YET.

TWO MAIN FCST ISSUES THIS MORNING. FIRST IS THE WIND. SECOND IS
THE POTENTIAL FOR RAIN ACROSS ERN LI.

MODEL STORM TRACK HAS CONSOLIDATED WITH THE 00Z RUNS. THE ECMWF
TRACKS ALONG THE 3Z SREF. GFS ABOUT 20MI NW OF THE ECMWF...AND
THE NAM SLIGHTLY E OF THE ECMWF.

QPF AND RESULTANT SNOWFALL FCST RELATIVELY UNCHANGED WITH A
GENERAL 6-18 INCHES LIKELY. LEAST AMOUNTS ACROSS THE W AND HIGHEST
AMOUNTS E...WHERE RAIN DOESN/T HOLD THE NUMBERS DOWN.

WITH REGARD TO THE RAIN...CLOSE PROXIMITY TO THE LOW MAY ALLOW
FOR THE COASTAL FRONT TO PENETRATE WWD INTO E-CNTRL LI. THE TWIN
FORKS ARE MOST SUSCEPTIBLE. AS THE LOW MAKES IT/S CLOSEST APPROACH
HOWEVER IT UNDERGOES OCCLUSION. IT SHOULD BE NOTED THAT H85
TEMPS NEVER RISE ABOVE FREEZING ACROSS THE CWA. FOR THIS REASON
HAVE KEPT THE AREA MOSTLY SNOW BUT THERE REMAINS UNCERTAINTY.
ANYWHERE FROM CNTRL LI WWD WILL BE ALL SNOW.

THE DEEP LOW WILL PRODUCE A POTENTIALLY DAMAGING WIND FIELD. BL
WINDS IN THE GFS OVER 60KT. NAM WIND FIELDS ARE WEAKER...BUT THE
DEEPER ECMWF GIVES SUPPORT TO THE GFS. FOR THIS REASON HAVE BUMPED
WIND GUSTS UP TO 45-60 MPH. LOCALLY HIGHER GUSTS POSSIBLE ACROSS
MOST OF LI. HAVE KEPT THE WARNINGS INTACT...BUT WILL INCLUDE
WORDING STATING THAT AN UPGRADE TO A BLIZZARD WARNING IS POSSIBLE.
BECAUSE THE HIGHEST WINDS...ESPECIALLY ACROSS THE INTERIOR...WILL
BE TONIGHT...THERE IS STILL TIME TO OBSERVE WHAT ENSUES OVER THE
OCEAN.

THE STORM WINDS DOWN MONDAY WITH STRONG WINDS CONTINUING. THE
ACCUMULATING SNOW APPEARS IT WILL BE OVER BY 15Z ATTM. DRY WITH
LESS WIND TUE.

&&

.LONG TERM /TUESDAY NIGHT THROUGH SATURDAY/...
NO CHANGES...

NORTHWEST FLOW BEGINS TO DIMINISH ON TUESDAY AS HIGH PRESSURE
BUILDS INTO THE REGION AND THE PRESSURE GRADIENT RELAXES. TUES
NIGHT THROUGH THU SHOULD BE DRY CONDITIONS AND HIGH TEMPS RIGHT
AROUND NORMAL...TOPPING OFF IN THE UPPER 30S AND LOWER 40S. GFS
INDICATES A WARM FRONTAL APPROACH THU NIGHT-FRI WHILE ECMWF KEEPS
THE FRONT WELL TO THE WEST...WILL TAKE THE MIDDLE GROUND AND
FORECAST ONLY SLIGHT CHANCE POP FOR SOME LIGHT PCPN AT THAT
TIME. SLIGHTLY WARMER ON FRI AND SAT WITH HIGHS IN THE LOWER AND
MID 40S. PCPN CHANCES BEGIN TO INCREASE LATE SAT AS A SFC SYSTEM
APPROACHES FROM THE OHIO VALLEY.

&&

.AVIATION /14Z SUNDAY THROUGH THURSDAY/...
A MAJOR WINTER STORM WILL IMPACT THE TERMINALS THIS AFTERNOON THROUGH
MONDAY WITH HEAVY SNOW AND HIGH WINDS.

VFR CONDITIONS WILL BE BRIEF BEFORE THE FIRST BAND OF SNOW MOVES IN FROM
THE SOUTH TOWARDS THE LATE MORNING AND EARLY AFTERNOON PERIOD.
CIGS LOWER TO MVFR WITH VERY LIGHT NON ACCUMULATING SNOW
INITIALLY. THEN SNOW INCREASES IN INTENSITY RESULTING IN A RAPID
DETERIORATION OF CONDITIONS TO IFR AND THEREAFTER BELOW IFR FOR
REST OF AFTERNOON AND FOR TONIGHT.

MESOSCALE BANDING WILL RESULT TO THE NW OF THE SFC LOW AS ITS
PRESSURE FALLS RAPIDLY. THIS BAND MAY LIKELY BE OVER THE NY METRO
WITH 1+" PER HOUR RATE POSSIBLE AFTER 19Z AND MORE LIKELY BY 21Z.
THUNDER SNOW POSSIBLE (NOT IN TAF) IN THE BAND.

SNOW TOTALS OF 11-15" EXPECTED.

NORTHERLY WINDS WILL GUST STARTING THIS AFTERNOON BETWEEN 20 AND
30 KT AND THEN BETWEEN 30 AND 45 KT FOR TONIGHT...WITH GUSTS
BETWEEN 40 AND 50 KT FOR KISP...KBDR...AND KGON. SOME OCCASIONALLY
HIGHER GUSTS WILL BE POSSIBLE.

OUTLOOK FOR 12Z MONDAY THROUGH THURSDAY...

MON...MOSTLY LIGHT SNOW WITH NO ACCUMULATING SNOW ON MONDAY
DAYTIME...BUT BLOWING SNOW IN NW 30 G 40 KT WND. CIGS GRADUALLY
IMPROVING TO MVFR/VFR BY LATE MON MORNING.
TUE...VFR...GUSTY NW WINDS.
WED AND THU...VFR.

&&

.MARINE...
ALL WATERS UPGRADED TO STORM. PEAK WINDS WILL BE AFTER DARK. STORM
FORCE WINDS MAY NOT OCCUR OUTSIDE OF THE OCEAN UNTIL THE TONIGHT
PERIOD...WITH MAINLY GALE FORCE WINDS LATE THIS AFTERNOON.

LOW WATER PROBLEMS ARE POSSIBLE AT THE TIMES OF LOW TIDE MON
AFTERNOON AND NIGHT AFTER PASSAGE OF THE LOW.

THEREAFTER...GALES CONTINUE FROM MON INTO TUE...FOLLOWED BY GRADUALLY
DIMINISHING WINDS TUE NIGHT.

&&

.HYDROLOGY...
SNOW SUNDAY THROUGH MONDAY AFTERNOON WILL GENERALLY YIELD LIQUID
EQUIVALENT AMOUNTS OF 0.75 TO 1.50 INCHES...HEAVIEST FROM NYC EAST
INTO SOUTHERN CT AND EASTERN LONG ISLAND. NO HYDROLOGIC IMPACTS
ARE EXPECTED DUE TO ITS FROZEN STATE...AND LITTLE SUBSEQUENT
MELTING OF ANY SNOW PACK AS LONG TERM HIGH TEMPS BARELY REACH THE
LOWER 40S MAINLY IN URBAN/COASTAL SECTIONS DURING MID TO LATE
WEEK.

&&

.TIDES/COASTAL FLOODING...
WITH LOW PRESSURE RAPIDLY DEEPENING OFFSHORE THROUGH TONIGHT...THERE
IS THE POTENTIAL FOR WIDESPREAD MINOR COASTAL FLOODING AND EVEN
ISOLATED MODERATE COASTAL FLOODING TOWARDS WESTERN LONG ISLAND SOUND
FOR THE HIGH TIDE CYCLE LATE TONIGHT INTO EARLY MONDAY MORNING.

GFS STORM SURGE GUIDANCE SHOWS ABOUT 2 TO 3 FT OF STORM SURGE ON
AVERAGE FOR LATE TONIGHT INTO EARLY MONDAY. A COASTAL FLOOD WATCH
HAS BEEN ISSUED FOR ALL OF THE AREA SURROUNDING LONG ISLAND SOUND.
DESPITE A LOWER ASTRONOMICAL CYCLE NEAR HALF MOON AND UNCERTAINTY
IN THE MODEL GUIDANCE...IT IS PRUDENT TO ISSUE A WATCH ATTM WITH
SOME GUIDANCE SUGGESTING 5 FT TIDAL DEPARTURES ON THE SOUND. THE
MOST SUSCEPTIBLE AREAS ATTM ARE ALONG THE N SHORE OF LI AND INTO
QUEENS DUE TO THE FCST NLY WIND DIRECTION. SMALL CHANGES IN THE
TRACK HOWEVER WILL INFLUENCE WIND DIRECTION...AND ANY WWD TREND IN
THE ACTUAL LOW WOULD FAVOR NE WINDS AND GREATER IMPACTS TO CT.
