AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE TAUNTON MA
540 AM EST TUE DEC 13 2005

.SHORT TERM (REST OF TODAY)...
UPDATED FORECAST TO REFLECT CLOUD COVER OVER ALL OF ESSEX COUNTY
INTO GREATER BOSTON AREA. ALSO INCLUDED SLIGHT CHANCE POPS FOR SHSN
THIS MORNING FOR WESTERN ESSEX COUNTY AND THE GREATER BOS AREA.

&&

.PREVIOUS DISCUSSION...
(ISSUED 355 AM EST TUE DEC 13 2005)

SHORT TERM (TODAY THROUGH WEDNESDAY)...
FOR THIS PERIOD SYNOPTIC SITUATION IS CUT...DRY...AND COLD FOR
INTERIOR SECTIONS...BUT EAST OF THE CAPE COD CANAL NEED TO REVIEW
THE MESOSCALE PROCESSES TO DETERMINE FORECAST.

ON THE BIG SCALE SURFACE HIGH PRESSURE BUILDS OVER NEW ENGLAND AND
SOUTHERN QUEBEC TODAY THROUGH WEDNESDAY. 500MB TROUGH PASSES
OVERHEAD THIS AFTERNOON AFTERWHICH RISING HEIGHTS.  SO OVER THE
INTERIOR BENIGN WEATHER WITH LITTLE IN THE WAY OF CLOUDS...BUT MUCH
IN THE WAY OF COLD.  WITH ARCTIC AIR SETTLING OVER
REGION...RADIATIONAL COOLING TONIGHT WILL ENABLE TEMPERATURES TO
PLUMMET INTO THE SINGLE DIGITS OVER THE INTERIOR WITH SOME READINGS
DROPPING BELOW ZERO. NO DOUBT COLDEST NIGHT OF THE SEASON TONIGHT.
FOR TUESDAY AND WEDNESDAY GOING WITH HIGHS IN THE 20S TO LOW 30S.
OVERALL FOLLOWED A BLEND OF GFS AND NAM MOS WITH HEAVIER ON NAM MOS.

NOW FOR EAST OF CAPE COD CANAL...LOOKS LIKE MORE OF A WINDEX EVENT TO
UNFOLD THIS MORNING OVER MID AND OUTER CAPE AS ARCTIC AIR INITIALLY
SPILLS OVER RELATIVELY WARMER OCEAN WATERS. CURRENT SATELLITE AND
RADAR SHOWS STRATO CU DECK AND -SHSN/FLURRIES MOVING ACROS CAPE ANN
AND EXPECT THIS TO TRANSLATE TO OUTER CAPE THROUGH THE MORNING HOURS.
THE DRY ARCTIC AIRMASS WILL PICK UP MOISTURE ON ITS TRAVEL SE. ADDING
TO THE MOISURE...1000-850MB OMEGA SWINGS ACROSS OUTER CAPE AS SHOWN
BY BOTH GFS AND NAM12. SO WITH MOISTURE...LIFT...AND UNSTABLE
SOUNDINGS FROM THE SURFACE TO JUST UNDER 850MB...THINKING THAT SQUALL
LIKE CONDITIONS WILL OCCUR BETWEEN 12-16Z...THEN TAPER OFF BY 18Z AS
WE LOSE LOW LEVEL LIFT. ACCUMULATIONS OF SNOW SHOULD BE AROUND AN
INCH OR LESS.

THEN WE TURN OUR ATTENTIONS TO TUESDAY NIGHT AND EARLY WEDNESDAY
EAST OF THE CANAL FOR OCEAN EFFECT SNOW SHOWERS.  MODELS INDICATING
UNIDIRECTIONAL NORTHERLY WIND FLOW FROM THE SURFACE THROUGH ABOUT
900MB. BASED ON LOCAL STUDY...FAVORABLE PATTERN AND THRESHOLDS BEING
MET OR EXCEEDED TUESDAY NIGHT...SUCH AS SUBSIDENCE INVERSION ABOVE
850MB...LAKE INDUCED CAPE GREATER THAN 400J/KG...NORMALIZED CAPE
GREATER THAN 0.18...AND DIFFERENCE BETWEEN SST AND 900-850MB GREATER
THAN 20C. ALL THIS POINTS TOWARD ACCUMULATING SNOW. BUT TO ISSUE AN
ADVISORY AT THIS TIME IS THE QUESTION.

SOME CONCERNS TO NOT ISSUE A SNOW ADVISORY ARE THAT GFS AND NAM12
MODEL CROSS SECTIONS ARE NOW LIMITING LOW LEVEL LIFT AND INCREASING
MEAN WIND SPEED IN THE MIXED LAYER. THE LACK OF LIFT IS NOT SO MUCH A
CONCERN...BUT AVERAGE WIND ALTHOUGH NORTHERLY...IS BORDERING 25KTS.
THIS SPEED WILL ACT TO LIMIT PARCEL RESIDENCE TIME OVER THE OUTER
CAPE...BUT GIVES GREATER CONFIDENCE THAT DOWNSTREAM NANTUCKET WILL
GET A BOUT OF THE OES...AND A NORTHERLY WIND GIVES GREATER CONFIDENCE
THAT THE MID CAPE WILL SEE SNOW. SO...EXPECT THE SNOW...BUT THINKING
UNFAVORABLE MEAN WIND SPEED WILL LIMIT SNOWFALL AMOUNTS JUST BELOW
ADVISORY. NEXT SHIFT CAN RE-EVALUATE AND WE STILL HAVE TIME TO ISSUE
A SNOW ADVISORY IF NEED BE.

QPF...INTERESTING IS THAT OPERATIONAL GFS HAS BEEN POINTING TOWARD
ACCUMULATING SNOW ON OUTER CAPE FOR THE PAST 5 NIGHTS. LATEST
ENSEMBLE MEMBERS ARE ALSO GIVING QPF OVER CAPE. GIVEN THOUGHTS ABOVE
WILL GO WITH A 1 TO 3 INCH TOTAL FOR TONIGHT AND CONTINUE WITH SPS.

BESIDES SUNSHINE AND DAYTIME HEATING ON WEDNESDAY...850MB RIDGE AXIS
AND SUBSIDENCE BECOMES MORE A FACTOR BY WEDNESDAY
AFTERNOON...SHRINKING DEPTH OF OCEAN EFFECT MIXED LAYER MACHINE...AND
THEREBY PUTTING AN END TO THE SNOW.

LONG TERM (WEDNESDAY NIGHT THROUGH MONDAY)...
LINGERING COLD AIR OVER THE WATERS (-10 TO -12C AT 850 MB) WITH LOW
LEVEL UNIDIRECTIONAL FLOW AND WITH SPEEDS OF OVER 12 KNOTS DURING
WEDNESDAY EVENING.  THE FLOW IS NNW GRADING TO NW. THIS IS ENOUGH TO
CONTINUE OCEAN EFFECT SHOWERS WITH THE FETCH POINTING TO EITHER THE
OUTER CAPE OR JUST OFFSHORE.  THE FLOW DIMINISHES AND TURNS
OVERNIGHT AND LESS COLDER AIR MOVES IN ALOFT...SO THESE SHOWERS
SHOULD DIMINISH OVERNIGHT.  ELSEWHERE HIGH PRESSURE BUILDS IN TO
BRING FAIR SKIES AND CHILLY TEMPS.

THE MAIN CONCERN THIS FORECAST PERIOD IS THE DEVELOPING STORM FOR
LATE IN THE WEEK.  THE 00Z GFS IS A TAD SLOWER AND FARTHER WEST WITH
THE TRACK OF THE SURFACE LOW UP THE COAST.  WITH A NEGATIVE TILT
TROF ALOFT SUCH A TRACK IS REASONABLE...AND THE LACK OF A GOOD
MARITIMES HIGH TAKES AWAY A POTENTIAL COLD AIR ANCHOR. HOWEVER BOTH
THE GFS AND THE GLOBAL HINT AT SOME COLD AIR DAMMING IN THEIR MSLP
PATTERNS AT 12Z FRIDAY.  AND THE GFS FORECASTS A 45-50 KNOT LOW
LEVEL AGEOSTROPIC FLOW OVER THE INTERIOR FRIDAY MORNING WHICH WOULD
WORK AGAINST THE TENDANCY FOR THE FLOW THERE TO TURN EAST AND MILD.
WITH THE SLOWER TIMING...THICKER CLOUDS WOULD ARRIVE LATER IN THE
DAY THURSDAY AND PRECIPITATION NOT UNTIL AFTER MIDNIGHT.  A FURTHER
THOUGHT IS THAT ANY TENDANCY TO HOLD COLD AIR IN THE INTERIOR MAY
ALSO ENCOURAGE A MORE EASTERLY TRACK IN THE COASTAL LOW.

WITH ALL OF THESE FACTORS IN MIND...WE HAVE SLOWED THE ONSET OF
CLOUDS AND PRECIP BY AROUND 6 HOURS.  THIS KEEPS SKIES SUNNY FOR THE
START OF THURSDAY AND HOLDS OFF THE OVERCAST UNTIL NIGHT.  CHANCE
POPS MOVE INTO THE CT AND WESTERN MASS ZONES TOWARD MIDNIGHT WITH
LIKELY POPS STILL EXPECTED IN ALL ZONES BY MORNING.

THE PRECIP TYPE STILL LOOKS LIKE A MESS.  ONSHORE FLOW OFF 44 DEGREE
WATER FAVORS A WARMING OF THE LOWER LAYERS AND RESULTING CHANGE TO
RAIN.  ANY STRONG AGEOSTROPIC DRAINAGE FLOW IN THE INTERIOR WILL
RESIST THIS AND RETAIN LOW LEVEL COLD AIR.  SO WE WILL GO WITH A
CHANGE TO RAIN ALONG THE COAST...BUT A MIX INLAND OF I-95.

WE HAVE ALSO ENDED THE PRECIP SOONER FRIDAY NIGHT BASED ON MOVEMENT
OF THE SURFACE LOW.

AVIATION...
VFR TODAY AND TONIGHT FOR ALL BUT HYA AND ACK. FOR HYA AND
ACK...CEILINGS TO LOWER TO MVFR LATER THIS MORNING WITH SCATTERED
SHSN. A BRIEF IMPROVEMENT THIS AFTERNOON TO VFR...ONLY TO LOWER TO
MVFR TONIGHT DUE TO OCEAN EFFECT SNOW SHOWERS.

MARINE...
COLD AIR ADVECTION OVER WARM WATERS WILL YIELD BRISK NORTHERLY WIND
GUSTS TO AROUND 25 KTS TODAY THROUGH WEDNESDAY OVER MOST OUTER
WATERS. BOS HARBOR AND NARR BAY WILL BE BELOW SCA THROUGH WED AND
BUZZ BAY/MVY SOUND/ BID AND RID SOUNDS SHOULD REMAIN JUST UNDER
SCA...EXCEPT FOR TONIGHT. SEAS WILL CONTINUE TO REMAIN ROUGH OVER
OUTER WATERS THROUGH THURSDAY MORNING.

THE MAIN CONCERN ON THE WATERS WILL COME WITH THE THURSDAY
NIGHT/FRIDAY COASTAL LOW.  THE GRADIENT IS TIGHT ENOUGH TO SUPPORT
AT LEAST SMALL CRAFT SUSTAINED WINDS...AND WITH 60 KT WINDS MOVING
OVERHEAD AT 950 MB WE ARE CONCERNED WITH THE POTENTIAL FOR GALE
FORCE GUSTS.  THE GFS ALSO BRINGS 35-40 KTS WITHIN MIXING RANGE OF
THE SURFACE FRIDAY EVENING...LEAVING A POTENTIAL FOR SUSTAINED GALES
AT THAT TIME.  ALL FACTORS TO BE WATCHED.

SCATTERED SNOW SHOWERS WILL DEVELOP OVER THE MID AND OUTER CAPE THIS
MORNING...POSSIBLY GRAZING THE ISLAND OF NANTUCKET BY NOON. THERE
WILL BE A BRIEF BREAK IN THE ACTION THIS AFTERNOON...BEFORE A SECOND
ROUND OF SNOW SHOWERS DEVELOPS THIS EVENING AND CONTINUES THROUGH
WEDNESDAY MORNING.

THE FIRST BATCH OF SNOW SHOWERS THIS MORNING WILL ACCOMPANY AN ARCTIC
FRONT SWEEPING ACROSS THE EAST COASTAL WATERS VIA BRISK NORTHWEST
WINDS. SNOW SQUALLS WILL BE POSSIBLE FOR A TIME THIS
MORNING...ESPECIALLY OVER THE OUTER CAPE FROM PROVINCETOWN TO
CHATHAM...WHERE AROUND AN INCH OF SNOW ACCUMULATION IS POSSIBLE.
SCATTERED SNOW SHOWERS WILL THEN TAPER OFF FOR A TIME THIS AFTERNOON.

WINDS WILL TURN NORTHERLY THIS AFTERNOON AND CONTINUE THROUGH
WEDNESDAY MORNING. A PROLONGED COLD BRISK NORTHERLY WIND BLOWING
ACROSS THE RELATIVELY WARM OCEAN WATERS...WILL CAUSE THE DEVELOPMENT
OF OCEAN EFFECT SNOW SHOWERS TONIGHT. THE FAVORABLE LOCATIONS FOR
OCEAN EFFECT SNOW SHOWERS TONIGHT WILL BE ACROSS THE MID AND OUTER
CAPE...AND THE ISLAND OF NANTUCKET. THE CURRENT FORECAST IS FOR A 1
TO 3 INCH SNOW ACCUMULATION. HOWEVER...THERE EXISTS THE POTENTIAL FOR
HIGHER AMOUNTS OF 2 TO 5 INCHES EAST OF HYANNIS. WEST OF HYANNIS...
LITTLE IF ANY ACCUMULATION IS EXPECTED. FOR NANTUCKET...LESS SNOW IS
EXPECTED WITH 1 TO AS MUCH AS 2 INCHES POSSIBLE.

IF LATER FORECASTS INDICATE GREATER CERTAINTY THAT SNOW
ACCUMULATIONS WILL BE ON THE ORDER OF 2 TO 5 INCHES TONIGHT...A SNOW
ADVISORY WILL BE ISSUED THIS AFTERNOON.
