Coastal low pressure rapidly intensified Saturday night as it tracked northeast from off the Delmarva Coast, just southeast of the 40N/70W benchmark, and to southeast of Cape Cod by Sunday morning. Gale force north to northeast winds developed high surf which pounded the shoreline through the weekend.

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE NEW YORK NY
705 AM EST SAT DEC 19 2009
.SYNOPSIS...
A POWERFUL COASTAL STORM WILL BRING A SWATH OF HEAVY SNOW AND
STRONG WINDS TO THE REGION THIS AFTERNOON INTO SUNDAY MORNING.
CANADIAN HIGH PRESSURE WILL THEN BUILD IN THROUGH THE MIDDLE OF
NEXT WEEK. A COMPLEX LOW PRESSURE SYSTEM WILL IMPACT THE REGION BY
THE END OF NEXT WEEK.
&&
.NEAR TERM /UNTIL 6 AM THIS MORNING/...
7AM UPDATE...
INTENSE MESOSCALE BANDS DEVELOPING ACROSS SOUTHERN NJ AND DELMARVA
AS OF 7AM THIS MORNING. SNOWFALL RATES OF 1 TO 2 INCHES PER HOUR
IN THESE BANDS. THIS HEAVY SNOW ACTIVITY IS EXPECTED TO GRADUALLY
WORK NORTH INTO THE NY/NJ METRO AND LONG ISLAND THIS
AFTERNOON...WITH QUICKLY DETERIORATING CONDS. WINDS ARE EXPECTED
TO PICK UP LATE THIS AFTERNOON...WITH NEAR BLIZZARD CONDS
POSSIBLE. THE QUESTION IS STILL HOW FAR NORTH AND WEST THE BANDING
WILL GET. BEST ESTIMATE IS NY/NJ METRO...SOUTHERN LOWER HUDSON
VALLEY...AND SW CONN AND POINTS EAST. WILL UPDATE GRIDS TO REFLECT
SLIGHTLY EARLIER ONSET OF HEAVY SNOW ACROSS SOUTHERN ZONES.
PREVIOUS AFD...A DEEPENING MID/UPPER TROUGH OVER OHIO VALLEY WITH
100+ KT UPPER JET ROUNDING THE BASE THROUGH THE TENNESSEE
VALLEY...ALLOWING FOR DEEPENING OF LOW PRESSURE OFF THE CAROLINA
COAST THIS MORNING...WITH STRONG PRESSURE FALLS NE OF CAPE
HATTERAS.
MODELS NOT EXHIBITING ANY SIGNIFICANT INITIALIZATION ERRORS EARLY
THIS MORNING...WITH VERY GOOD AGREEMENT IN EXPLOSIVE DEVELOPMENT
OF LOW PRESSURE AS IT TRACKS FROM OFF THE CAROLINA COAST EARLY
THIS MORNING TO ABOUT 125 MILES EAST OF THE DELMARVA COAST BY THIS
EVENING...AS A RESULT OF THE STRENGTHENING NORTHERN STREAM JET AND
MID/UPPER TROUGH ENERGY SWINGING TOWARDS THE COAST.
SATELLITE IMAGERY DENOTING THE INTENSE UVV AHEAD OF THE JET
STREAK AND TO THE NW OF THE DEVELOPING LOW ACROSS THE MID ATLANTIC
WITH RAPIDLY COOLING CLOUD TOPS AND GRAVITY WAVE FEATURES.
MAIN QUESTION TODAY IS HOW QUICKLY SNOW MOVES INTO THE REGION.
NAM/GFS BLEND OF ONSET LOOKS TO BE BEARING OUT THE BEST EARLY THIS
MORNING. LIGHT SNOWFALL INTO CENTRAL NJ AS OF AROUND 4 AM. QUITE
A BIT OF LOW-LEVEL DRY AIR TO OVERCOME INITIALLY...WITH JUST SOME
LIGHT SNOW DEVELOPING FROM S TO E THIS MORNING. BUT WITH
INCREASING ISENTROPIC LIFT AND MOISTURE ADVECTION THIS
AFTERNOON...EXPECTING SNOW TO INCREASE INTENSITY FROM SW TO NE
FROM MID AFTERNOON INTO THIS EVENING...WITH RAPID DETERIORATION IN
CONDS ACROSS NY/NJ METRO AND LI...WITH 2 TO 4 INCHES POSSIBLE BY
AROUND 8 PM. LESSER AMOUNTS N/NE
NE WINDS INCREASING TO 15 TO 25 MPH WITH GUSTS UP TO 35 MPH ALONG
THE COAST LATE TODAY.
TEMPS LIKELY CLIMB INTO THE LOWER 30S TO AROUND 35
CITY/COAST AND MID/UPPER 20S COAST...BUT DROPPING ONCE SNOW
BEGINS TO FALL.
&&
.SHORT TERM /6 AM THIS MORNING THROUGH 6 PM SUNDAY/...
MODELS IN VERY GOOD AGREEMENT WITH SYNOPTIC FEATURES OF THE
INTENSIFYING MID/UPPER TROUGH SLIDING FROM THE OHIO VALLEY AND
THEN JUST SE OF THE REGION TONIGHT WHILE CUTTING OFF. THIS IN
COMBO OF INTENSIFYING UPPER JET ALLOWING FOR COASTAL LOW PRESSURE
TO CONTINUE TO BOMB AS IT TRACKS FROM THE DELMARVA THIS
EVENING...JUST SE OF THE 40/70 BENCHMARK...AND TO SE OF CAPE COD
BY SUN MORNING.
IDEAL PLACEMENT OF ARCTIC HIGH PRESSURE OVER THE SOUTHERN
CANADIAN PLAINS...RIDGING INTO SOUTHERN QUEBEC AND ONTARIO AND
TRACK OF MID/SURFACE LOW PRESSURE SHOULD MAINTAIN THIS AS AN ALL
SNOW EVENT ACROSS THE REGION.
ALL THE INGREDIENTS ARE THERE FOR MESOSCALE BANDING...WHERE
SNOWFALL RATES OF 1 TO 3 INCHES AN HOUR ARE POSSIBLE TONIGHT...BUT
QUESTION IS WHERE EXACTLY THIS SETS UP. EMBEDDED CONVECTION
POSSIBLE AS WELL IN THIS BAND. ENSEMBLE/OPER MODEL FIELDS HAVE
PLACED THIS ANYWHERE FROM NY/NJ METRO INTO SOUTHERN PORTIONS OF
LOWER HUDSON VALLEY AND EXTREME SW CONN...OR SOUTHEAST TO EASTERN
LI AND EXTREME SE CONN. THE OTHER UNCERTAINTY WOULD BE THAT TO THE
NW OF THIS BAND...SUBSIDENCE AND CAA WOULD RAPIDLY CUT OFF SNOW
AMOUNTS. FOR THIS REASON HAVE MAINTAINED A WINTER STORM WATCH
ACROSS ORANGE AND PUTNAM COUNTY. POTENTIAL IS THERE FOR SIX OR
MORE INCHES OF SNOW IF BANDING DEVELOPS FAR ENOUGH NW...BUT IF NOT
THE REGION MAY ONLY SEE LOW END ADVISORY AMOUNTS. WITH POSSIBLE
WARNING/ADVISORY LEVEL SNOWS NOT EXPECTED UNTIL TONIGHT HAVE
CONTINUED WATCH THERE AND WILL LET DAYSHIFT MONITOR RADAR/BANDING
TRENDS THOUGH EARLY THIS AFTERNOON AND ISSUE. OTHERWISE REMAINDER
OF WSW PRODUCTS REMAIN AS IS.
IN ADDITION...IF THE BAND DEVELOPS ACROSS NY/NJ METRO AND N...THEN
FAR SE SECTIONS OF MAY SEE SOME DRY SLOTTING. FOR THIS
REASON...HAVE NOT TRIED TO PINPOINT LINE...BUT BASED ON A ENSEMBLE
QPF APPROACH HAVE GONE WITH A GENERAL 10 TO 15 INCHES FROM NY/NJ
METRO AND POINTS NE AND E. HIGHER AMOUNTS POSSIBLE WHERE BAND
DEVELOPS...SLIGHTLY LOWER AMOUNTS POSSIBLE TO THE SE AND
SIGNIFICANTLY LOWER TO THE NW.
STRONG PRESSURE FALLS AND TIGHT GRADIENT TONIGHT WILL HAVE WINDS
INCREASING ALONG THE COAST TO 20 TO 25 MPH WITH GUSTS OF 35 TO 40 MPH.
HAVE CONTINUED BLIZZARD WARNING AS IS ACROSS LONG ISLAND...WHERE
WIND GUSTS OF 40 TO 45 MPH ARE POSSIBLE...ESPECIALLY EASTERN LI.
INCREASED FRICTIONAL EFFECTS WITH N FLOW OVER SE CONN AND NYC SHOULD
KEEP CONDS MAINLY BELOW BLIZZARD. HIGHEST PROB OF BLIZZARD CONDS IN
WARNED AREA EXPECTED LATE TONIGHT INTO SUN MORNING AS TEMPS DROP
WELL DOWN INTO THE 20S AND SNOW BECOMES LIGHTER COMBINED WITH
STRONG WINDS.
HEAVIEST PERIOD OF SNOW EXPECTED BETWEEN 00 TO 12Z WITH BEST
DYNAMICS...GRADUALLY TAPERING OFF FROM W TO E IN LIGHT TO MODERATE
DEFORMATION BANDING SUN MORNING INTO THE AFTERNOON AS UPPER TROUGH
PIVOTS NE. LIGHT ADDITIONAL ACCUM...PARTICULARLY EAST. SNOW
SHOULD FINALLY COME TO AN END ACROSS EASTERN SECTIONS BY MID
AFTERNOON. TEMPS MAXING OUT UPPER 20S INTERIOR AND LOWER 30S
COAST.
&&
.LONG TERM /SUNDAY NIGHT THROUGH FRIDAY/...
THE COASTAL LOW WILL SLOWLY MOVE TOWARDS NOVA SCOTIA WITH HIGH
PRESSURE GRADUALLY BUILDING IN FROM THE WEST. SKIES WILL PARTIALLY
CLEAR AND WEATHER SHOULD BE DRY THROUGH MID-WEEK. TEMPERATURES
LOWERED ON GUIDANCE THROUGH THE PERIOD TO ACCOUNT FOR EXPECTED SNOW
COVER. BREEZY NORTHWESTERLY WINDS SHOULD SUBSIDE BY WEDNESDAY AS
RIDGE AXIS CENTERS OVER THE REGION.
TEMPERATURES WILL GRADUALLY WARM TUESDAY THROUGH FRIDAY WILL AS A
HIGH PRESSURE RIDGE MOVES OFFSHORE. SURFACE FLOW TURNS MORE EASTERLY
ON THURSDAY AND EVENTUALLY SOUTHERLY OUT AHEAD OF NEXT SYSTEM BY
EARLY FRIDAY.
QUITE A BIT OF UNCERTAINTY WITH STORM SYSTEM FOR THE END OF THE
UPCOMING WEEK. GFS BRINGS THINGS IN FASTER AND IS WARMER THAN THE
ECMWF. FOR NOW RUNNING WITH CHANCE POPS CHRISTMAS EVE NIGHT AND
CHRISTMAS DAY...WITH SNOW CHANGING TO A RAIN SNOW MIX.
&&
.AVIATION /12Z SATURDAY THROUGH WEDNESDAY/...
VFR CIGS/VSBYS THROUGH TONIGHT. HIGH IMPACT WINTER STORM EXPECTED
SATURDAY INTO SUNDAY.
FOR KJFK/LGA/KEWR...ONSET OF LIGHT SNOW 18-21Z. HOWEVER...WITH
VERY DRY AIR AT THE SFC...IT IS POSSIBLE THAT PRECIP ONSET COULD
BE DELAYED. HOWEVER IT IS ALSO POSSIBLE THAT CONDITIONS REACH IFR
SOONER THAN FORECAST ONCE THE SNOW BEGINS. SO...WHILE CONFIDENCE
IN THE OCCURRENCE OF SNOW IS HIGH...THE FINER DETAILS MAY CHANGE
AS THE STORM DRAWS CLOSER.
WHILE NOT YET IN TAFS...EXCEPT AT KISP...PERIODS OF VLIFR WITH VSBY
NEAR ZERO POSSIBLE (ONLY GO TO 1/2 MILE ON VSBY AT KISP FOR
NOW)...ESP ACROSS LONG ISLAND AND EASTERN CT SAT NIGHT. HAVE STRONG
GUSTY WINDS LIKELY TO CREATE BLOWING AND DRIFTING OF SNOW ACROSS
RUNWAYS.
SNOWFALL RATES INCREASE INTO THE EVENING. POSSIBLE ACCUMULATION
RATES:
JFK/EWR/LGA/TEB/HPN/BDR...UP TO AN INCH PER HOUR THROUGH ABOUT 01Z
SUN...THEN UP TO 1-2 INCHES PER HOUR THROUGH ABOUT 06Z.
ISP/GON...UP TO 1-2 INCHES PER HOUR THROUGH ABOUT 01Z SAT...THEN
UP TO 2-3 INCHES PER HOUR WITH LOCALLY HIGHER AMOUNTS THROUGH
ABOUT 09Z.
SWF...MAY SEE UP TO AN INCH PER HOUR IF BANDING SETS UP. STILL MOST
UNCERTAIN ABOUT AMOUNT/DURATION HERE.
CONDITIONS SLOWLY IMPROVE SUNDAY MORNING...BUT WINDS REMAIN GUSTY
THROUGH SUNDAY AFTERNOON.
OUTLOOK 00Z MONDAY THROUGH WEDNESDAY...
SUN NIGHT - WED...VFR.
&&
.MARINE...
LOW PRES WILL TRACK FROM NEAR HATTERAS THIS MRNG TO ABOUT 165 NM SE
OF MONTAUK SUN MRNG. THE LOW WILL RAPIDLY DEEPEN AS IT TRACKS OVER
THE ATLANTIC DURING THIS TIME PERIOD. WINDS WILL STEADILY INCREASE
THRU THIS AFTN...WITH PEAK WINDS TO OCCUR TNGT.
FLAGS WILL REMAIN UNCHANGED WITH THIS FCST. THE DEPTH AND TRACK OF
THE LOW CONTINUES TO SUPPORT STORM CONDITIONS ON THE ERN OCEAN WITH
GALES ELSEWHERE. ANZ355 MAY NEED TO BE UPGRADED TO STORM FOR TNGT
DEPENDING ON HOW THE LOW AND RESULTANT WINDS ARE TRENDING. FOR NOW
WINDS FCST TO 45 KT...WITH THE MOST LIKELY AREA TO HIT STORM IN THE
SERN PORTION.
FOR SEAS...UP TO 15 FT OCEAN. 6 FT CNTRL SOUND WITH PORTIONS OF THE
ERN SOUND BUILDING TO CLOSE TO 8 FT.
WINDS DIMINISH SLOWLY SUN. THE HARBOR WILL BE THE FIRST TO END GALES
WITH A CANCELLATION BY NOON POSSIBLE.
LOW PRES REMAINS OVER THE N ATLANTIC WITH HI PRES BUILDING IN ACROSS
THE CNTRL CONUS THRU WED. THIS WILL RESULT IN PERSISTENT SCA
CONDITIONS WITH PERIODS OF GALES ON NW FLOW. A BRIEF LULL WILL OCCUR
IN THE THU TIME PERIOD IN ADVANCE OF THE NEXT LOW PRES SYSTEM.
&&
.HYDROLOGY...
STRONG STORM WILL RESULT IN ABOUT 1 TO 1 1/2 INCH ACROSS SE
2/3RDS OF THE REGION...TAPERING TO 1/4 TO 1/2 INCH ACROSS FAR NW
ZONES. THIS IN THE FROM OF SNOW AND SLOW DAYTIME MELTING WILL
OCCUR THEREAFTER.
&&
.TIDES/COASTAL FLOODING...
A STRONG N/NE FLOW AND STRONG PRESSURE FALLS EXPECTED LATE TODAY
INTO TONIGHT AS A POWERFUL COASTAL LOW APPROACHES THE REGION.
TIDAL DEPARTURES OF 2 1/2 TO 3 FT ABOVE NORMAL EXPECTED DURING THE
TIMES OF HIGH TIDE TONIGHT...WHICH IS EXPECTED TO CAUSE MINOR
COASTAL FLOODING ALONG NEW YORK HARBOR...THE SOUTHERN BAYS OF
QUEENS...BROOKLYN AND LONG ISLAND...THE NORTH SHORE OF LONG
ISLAND...THE EASTERN BAYS OF LONG ISLAND...AND ALONG WESTERN LONG
ISLAND SOUND DURING THE TIMES OF HIGH TIDE.
