AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE TAUNTON MA
400 PM EST SAT JAN 22 2011

.SYNOPSIS...
A DRY ARCTIC COLD FRONT WILL APPROACH FROM THE NORTH TONIGHT...
PUSHING ACROSS THE REGION SUNDAY MORNING. THIS WILL USHER IN
BITTERLY COLD WEATHER LATE SUNDAY AFTERNOON THROUGH MONDAY MORNING.
A STRONG COASTAL STORM IS POSSIBLE MIDWEEK ALONG WITH THE POTENTIAL
FOR SIGNIFICANT PRECIPITATION TO AFFECT SOUTHERN NEW ENGLAND.

&&

.NEAR TERM /UNTIL 6 AM SUNDAY MORNING/...
HIGH CIRRUS DECK HAS MOVED ACROSS MOST OF THE REGION THIS AFTERNOON
FROM THE SW AS SEEN ON BOTH IR AND WV SATELLITE IMAGERY. THIS IS THE
OUTER EDGE OF DEVELOPING LOW PRES OFF THE CAROLINAS. THIS LOW WILL
DEEPEN AS IT PASSES WELL OFFSHORE TONIGHT.

WILL SEE GENERALLY LIGHT WINDS WITH A WEAKENING SHORT WAVE MOVING
INTO CENTRAL NEW ENGLAND OUT OF NY STATE. AFTER MIDNIGHT...WINDS
WILL BACK TO N-NW BUT REMAIN GENERALLY BELOW 10 MPH. SHOULD ALSO
NOTICE THE HIGH CLOUDS MOVING OFFSHORE. THIS SHORT WAVE WILL ALSO
USHER A DRY ARCTIC FRONT THAT WILL APPROACH LATE TONIGHT. NOT
EXPECTING ANY PRECIP WITH THIS...AS THIS FEATURE IS MOISTURE STARVED
EXCEPT FOR ANY LAKE EFFECT PRECIP IT PICKS UP AS IT MOVES TOWARD NEW
ENGLAND. NOTING LITTLE IF ANY PRECIP ACROSS NY STATE ON NE MOSAIC
RADAR LOOP.

HAVE REMOVED MENTION OF SLIGHT CHANCE POPS FOR CENTRAL AND NORTHERN
AREAS TONIGHT. A COUPLE OF STRAY SNOW SHOWERS MAY SNEAK ACROSS THE E
SLOPES OF THE BERKSHIRES AFTER MIDNIGHT.

CLOUDS WILL CONTINUE TO INCREASE WITH THE NY FEATURE MOVING
EAST...BUT WILL STILL BE A VERY COLD NIGHT. H850 TEMPS DROP TO -14C
TO -17C BY 12Z SUN...WHILE H925 TEMPS FALL TO -10C TO -14C FROM S-N.
EXPECT OVERNIGHT LOWS TO DROP BELOW ZERO ACROSS THE HIGHER TERRAIN
OF N CENTRAL AND W MA INTO S NH...RANGING TO AROUND 20 DEGREES ON
OUTER CAPE COD AND NANTUCKET.

&&

.SHORT TERM /6 AM SUNDAY MORNING THROUGH 6 PM SUNDAY/...
SUNDAY...ONCE THE ARCTIC FRONT CLEARS THE REGION SUNDAY MORNING...
THE COLDEST AIR OF THE SEASON WILL SPILL ACROSS THE REGION. EXPECT
N-NW WINDS AT 10-20 MPH...EXCEPT A BIT GUSTY ALONG THE COAST...
ESPECIALLY ACROSS THE CAPE AND ISLANDS. WITH VERY COLD AIR MOVING
OVER THE RELATIVELY WARMER OCEAN WATERS ALONG WITH A WITH A N-NW
WIND COMPONENT /ABOUT 340 DEGS/...COULD SEE SOME OCEAN EFFECT SNOW
SHOWERS DEVELOP ACROSS OUTER CAPE COD DURING THE DAY. HAVE PUT A
MENTION INTO THE GRIDS. COULD ALSO SEE SOME SMALL ACCUMULATIONS
THERE.

ELSEWHERE...WILL SEE GENERALLY PARTLY CLOUDY CONDITIONS BUT BECOMING
BITTERLY COLD EVEN WITH RELATIVELY GENTLE WINDS. AS H850 AND H925
TEMPS CONTINUE TO PLUMMET DURING THE DAY...HIGH TEMPS WILL STRUGGLE
TO REACH 20 DEGREES ACROSS INLAND AREAS...BUT WILL MAKE IT TO THE
LOWER-MID 20S ALONG THE S COAST.

SUNDAY NIGHT...THE BRUNT OF THE COLD AIR SURGE WILL CROSS THE REGION
SUNDAY NIGHT INTO MONDAY MORNING. HIGH PRES WILL BUILD W OF NEW
ENGLAND...WITH GENERALLY CLEAR SKIES ARE EXPECTED. COULD STILL SEE
SOME LOW CLOUDS GENERATED OFF CAPE COD BAY AND MASS BAY ACROSS THE
OUTER CAPE...BUT NOT EXPECTING MUCH IN THE WAY OF PRECIP THERE AT
THIS POINT.

EVEN THOUGH WINDS WILL BE GENERALLY AROUND 10 MPH OR LESS...EVEN THE
LIGHTEST WINDS WILL GENERATE EXTREMELY LOW WIND CHILL VALUES.
SO...WE HAVE ISSUED A WIND CHILL WATCH WHERE THE COLDEST VALUES ARE
EXPECTED...ACROSS S NH/N CENTRAL AND W MA INTO WESTERN HARTFORD
COUNTY. EXPECT WIND CHILL VALUES ON THE ORDER OF -20 TO -35 BY EARLY
MONDAY MORNING. WILL LIKELY SEE BELOW ZERO LOWS FOR BOTH BOSTON AND
PROVIDENCE EARLY MONDAY MORNING...THE FIRST OCCURRENCE OF BELOW ZERO
READINGS IN 6 YEARS...ON JANUARY 22 2005 /THE DAY PRIOR TO THE
BLIZZARD OF '05/.

&&

.LONG TERM /MONDAY THROUGH FRIDAY/...
HIGHLIGHTS...
* FRIGID AIRMASS SUN NIGHT INTO MON NIGHT
* POTENTIAL MAJOR WINTER STORM WED/THU

MONDAY AND MONDAY NIGHT...VERY COLD DAY WITH ABUNDANT SUNSHINE AS
ARCTIC PRESSURE MOVES OVER THE REGION. SHALLOW MIXING DEPTH AND
FRIGID START WILL LIKELY RESULT IN TEMPS REMAINING IN THE SINGLE
NUMBERS IN THE INTERIOR AND NEAR 10 OR LOW TEENS COASTAL PLAIN.
ANOTHER FRIGID NIGHT MON NIGHT WITH TEMPERATURES DROPPING TO -10 TO
-15 IN THE WEST AND 0 TO -5 IN THE EAST...WITH POSITIVE SINGLE
DIGITS ALONG THE IMMEDIATE COAST. THERE SHOULD BE INCREASING MIDDLE
AND HIGH LEVEL CLOUDINESS AFTER MIDNIGHT...BUT NOT UNTIL
TEMPERATURES HAVE HAD THE CHANCE TO PLUMMET.

TUESDAY...PREFERRING THE 00Z ECMWF WHICH HAS HIGH PRESSURE MOVING
OFF THE COAST AND WARM ADVECTION IN THE RETURN FLOW AROUND THE
HIGH. A CLOUDY DAY IS FORECAST AND THERE COULD EVEN BE SOME LIGHT
SNOW BREAKING OUT...WITH LITTLE OR NO ACCUMULATION EXPECTED. HAVE
INTRODUCED 20-30 PERCENT POPS.

TUESDAY NIGHT THROUGH FRIDAY NIGHT...

WITH POTENTIAL MID-WEEK COASTAL STORM...MDL SOLNS EXHIBITING A FAIR
AMOUNT OF SPREAD IN HANDLING MASS FIELDS FROM SFC-H5. THERE IS SOME
SUBSTANTIAL AGREEMENT AMONGST ECMWF/GEFS/GEM WITH THE FASTER OPER
GFS REMAINING THE FAR OUTLIER...NEVERTHELESS THERE IS STILL A LOT OF
UNCERTAINTY. HAVE GONE WITH THE 12Z ECMWF AS IT HOLDS THE MIDDLE
GROUND AND OFFERS A FAVORABLE SYNOPTIC APPROACH WHILE CONSIDERING A
BLEND OF MOS-GUIDANCE AND PREV FCSTR THINKING.

ECMWF HIGHLIGHTS NRN GULF SFC LOW DVLPMNT BY 18Z TUE MOVING NEWD
THRU THE CAROLINAS BY 12Z WED...AND NEAR THE BENCHMARK AND ACRS THE
ISLANDS AND CAPE BY 6-12Z THURS. QUESTIONS REMAIN AS TO THE GRIP OF
THE EWD RETREATING ARCTIC HIGH IN KEEPING COLD AIR IN PLACE AT THE
SFC. NOTABLY WITH A DEEP SNOW PACK...AND DEPENDENT ON THE OVERALL
MOVEMENT OF THE ANTICIPATORY COASTAL STORM...IT MAY BE DIFFICULT TO
SCOUR OUT COLDER AND DRIER AIR FOR INTERIOR PORTIONS OF NEW
ENGLAND...PSBLY DELAYING THE ONSET OF PRECIP.

BASED ON THE 12Z ECMWF...MOISTURE CONVERGENCE WILL LIKELY BE
ABUNDANT THRU THE ATMOS COLUMN AS ISENTROPIC LIFT OF HIGHER THETA E
AIR COUPLED WITH BEST UPR LVL DYNAMICS...LEFT EXIT RGN OF THE H3
JET...AND Q-VECT FORCING IS PREVALENT AROUND 0-6Z THURS OVER SRN NEW
ENGLAND. AS SUCH THIS WILL LIKELY BE THE PD OF HEAVIEST PRECIP THRU
THE FCST RGN.

PRECIP TYPE REMAINS TRICKY AND LIKELY A BETTER HANDLE WILL BE EXIST
AS WE GET CLOSER TO THE PERIOD. IT IS WORTH NOTING THAT THE LATEST
0Z ECMWF HAS TRENDED WARMER...SOMEWHAT CLOSE TO THE 0Z GEM. BUT AM
NOT CONFIDENT WARM AIR WILL PRESS SO FAR INTO THE INTERIOR WITH
ANTICIPATED COLD AIR IN PLACE...SO HAVE NEGATED THE MDL SOLN.

BEYOND THURS MORN...SFC LOW WILL DEEPEN NEWD THRU THE SERN CANADIAN
PROVINCES AND STRONG NWLY WINDS FOR LATE THURS INTO FRI USHERING
MUCH COLDER AIR INTO THE RGN. THERE IS EVIDENCE OF WEAK DISTURBANCES
THRU THE NERN CONUS WHICH WILL LIKELY RESULT IN CHC PRECIP AND
CLOUDS TO LINGER THRU THE WEEKEND.

&&

.AVIATION /20Z SATURDAY THROUGH THURSDAY/...
FORECASTER CONFIDENCE LEVELS...
  LOW...LESS THAN 30 PERCENT
  MEDIUM...30 PERCENT TO 60 PERCENT
  HIGH...GREATER THAN 60 PERCENT

THROUGH 00Z...HIGH CONFIDENCE FOR VFR CONDITIONS.

TONIGHT...HIGH CONFIDENCE FOR VFR CONDITIONS. LIGHT WINDS BECOMING
N-NW OVER CAPE COD AND NANTUCKET. LOW CHANCE OF SNOW SHOWERS OVER
THE OUTER CAPE AFTER 09Z WITH LOCAL MVFR CIGS/VSBYS.

KBOS TERMINAL...HIGH CONFIDENCE FOR VFR WITH LIGHT WINDS THROUGH
TONIGHT.

SUNDAY AND SUNDAY NIGHT...HIGH CONFIDENCE FOR VFR CONDITIONS AT MOST
LOCATIONS. MEDIUM CONFIDENCE FOR CIGS AT 030-040 AND SCATTERED SNOW
SHOWERS DURING SUNDAY WITH 340 DEG WIND. EXPECT WINDS TO BACK TO 320
DEGS SUNDAY AFTERNOON AND PUSH SHSN OFFSHORE. SMALL ACCUMULATION
POSSIBLE.

EXPECT N-NW WINDS TO GUST UP AROUND 20 KT ACROSS CAPE COD AND THE
ISLANDS THROUGH MOST OF THE DAY...DIMINISHING SUNDAY NIGHT.

OUTLOOK...MONDAY THROUGH WEDNESDAY...

MONDAY THROUGH MONDAY NIGHT...HIGH CONFIDENCE FOR VFR CONDITIONS
EXCEPT OCCASIONAL MVFR CONDITIONS WITH POSSIBLE FLURRIES FOR
OUTERMOST CAPE COD SUNDAY NIGHT.

TUESDAY AND TUESDAY NIGHT...OVERCAST CLOUDINESS COULD LOWER TO MVFR
CIGS AT TIMES AND THERE IS A LOW CHANCE OF MVFR VSBYS IN AREAS OF
LIGHT SNOW IN WARM ADVECTION AS HIGH PRESSURE MOVES OFF THE COAST.

WEDNESDAY...LIKELY A MAJOR COASTAL STORM WILL IMPACT THE REGION
WITH STRONG WINDS AND IFR CONDITIONS. LOW CONFIDENCE AND UNCERTAINTY
LIES IN TERMS OF TIMING OF PRECIPITATION AND PRECIPITATION TYPE.

&&

.MARINE...
TONIGHT...EXPECT LIGHT WINDS TO BECOME N-NW OVERNIGHT AS LOW PRES
PUSHING E FROM THE MID ATLC COAST STRENGTHENS. WINDS AND SEAS
FORECASTED TO REMAIN BELOW SMALL CRAFT CRITERIA.

SUNDAY AND SUNDAY NIGHT...AS A DRY ARCTIC FRONT PUSHES OFFSHORE
EARLY SUNDAY...EXPECT N-NW WINDS TO INCREASE TO SMALL CRAFT CRITERIA
DURING THE DAY. HAVE ISSUED SMALL CRAFT ADVISORY FOR MOST OF THE
OPEN WATERS. EXPECT N-NW WINDS TO GUST UP TO 25-30 KT MAINLY AWAY
FROM THE NEAR SHORE WATERS. SEAS WILL ALSO BUILD UP TO 4-6 FEET...
HIGHEST WELL OFFSHORE SUNDAY NIGHT.

EXPECT OCEAN EFFECT SNOW SHOWERS TO DEVELOP WITH THE ARCTIC AIR
MOVING OVER THE RELATIVELY WARMER OCEAN WATERS...MAINLY ACROSS THE
EASTERN WATERS BUT MAY BE CLOSE ENOUGH TO AFFECT THE OUTER CAPE FOR
A TIME SUNDAY. ALSO EXPECT LIGHT TO MODERATE FREEZING SPRAY OVER THE
OPEN WATERS MAINLY SUNDAY NIGHT.

OUTLOOK...MONDAY THROUGH WEDNESDAY...

MONDAY...SLOWLY DIMINISHING WINDS AS HIGH PRES BUILDS INTO THE
REGION. MODERATE FREEZING SPRAY AS ARCTIC AIR POURS INTO THE REGION.
OCEAN EFFECT SNOW SHOWERS STILL LIKELY OVER THE EASTERN MA COASTAL
WATERS.

TUESDAY...WINDS AND SEAS BELOW SCA THRESHOLDS EXCEPT SEAS BUILDING
TO NEAR 5 FT LATE TUESDAY SOUTHERN COASTAL WATERS.

TUESDAY NIGHT...SMALL CRAFT CONDITIONS AGAIN WITH SEAS BUILDING TO
A ROUGH 5 TO 10 FT AND WINDS NEARING GALE FORCE.

WEDNESDAY...LIKELY A POTENTIAL SIGNIFICANT COASTAL STORM WITH
STRONG GALES AND POSSIBLE STORM FORCE EASTERLY WINDS WILL IMPACT
THE EASTERN SHORES. THERE IS ALSO CHANCES FOR FREEZING SPRAY WITH
THIS STORM.
