AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE TAUNTON MA
348 PM EST FRI JAN 29 2010

.SYNOPSIS...
ARCTIC AIR WILL CONTINUE TO MOVE INTO SOUTHERN NEW ENGLAND TONIGHT
FOLLOWED BY HIGH PRESSURE SATURDAY. A COLD FRONT MOVES ACROSS THE REGION
SUNDAY NIGHT REINFORCING THE COLD AIR. HIGH PRESSURE FROM CANADA
THEN BRINGS MORE DRY WEATHER FOR MONDAY AND TUESDAY. WEAK LOW
PRESSURE PASSES SOUTH OF NEW ENGLAND WEDNESDAY...BUT MAY BRING A
CHANCE OF SNOW.

&&

.NEAR TERM /UNTIL 6 AM SATURDAY MORNING/...
WEST TO NORTHWESTERLY WINDS CONTINUE TO GUST UP TO 40 KTS ACROSS
SOUTHERN NEW ENGLAND THIS AFTERNOON. THESE WINDS WILL DIMINISH
SOMEWHAT OVERNIGHT AS THE PRESSURE GRADIENT CONTINUES TO WEAKEN AND
COLDEST AIR MOVES EASTWARD. A WIND ADVISORY REMAINS IN EFFECT THROUGH
6 PM. WHILE THE WINDS WILL DIMINISH BELOW ADVISORY CRITERIA SUSTAINED
WINDS WILL CONTINUE IN THE 10 TO 20 KT RANGE WITH GUSTS UP TO 35
KTS...PARTICULARLY ACROSS THE HIGHER TERRAIN. COUPLED WITH VERY COLD
TEMPERATURES /DOWN INTO THE SINGLE DIGITS BOTH ABOVE AND BELOW ZERO/
ACROSS MOST OF SOUTHERN NEW ENGLAND...WIND CHILLS WILL FALL INTO THE
NEGATIVE SINGLE DIGITS TO TEENS. THE LOWEST WIND CHILLS WILL BE
ACROSS THE EAST SLOPES OF THE BERKSHIRES...AND THE HIGHER TERRAIN OF
WORCESTER COUNTY WHERE WIND CHILLS IN THE -15 TO -20 RANGE WILL BE
COMMON. A WIND CHILL ADVISORY HAS ALSO BEEN ISSUED WITH THIS FORECAST
PACKAGE FOR THESE AREAS.

&&

.SHORT TERM /6 AM SATURDAY MORNING THROUGH SATURDAY NIGHT/...
HIGH PRESSURE CONTINUES TO BUILD INTO SOUTHERN NEW ENGLAND ON
SATURDAY ALLOWING FOR MOSTLY SUNNY TO SUNNY SKIES ACROSS THE AREA.
LATE IN THE DAY...HIGH CLOUDS ASSOCIATED WITH THE LOW PRESSURE
MOVING NORTHEAST OFF THE CAROLINA COAST MAY STREAM INTO THE SOUTHERN
PORTIONS OF THE REGION /SOUTH OF THE MASS PIKE...BUT MOST LIKELY
CONFINED TO THE SOUTH COAST AND COASTAL PLAIN/.

WILL BE SLIGHTLY WARMER ON SATURDAY...IF NOT IN ACTUAL TEMPERATURE
IT WILL AT LEAST FEEL WARMER WITH SIGNIFICANTLY LOWER WINDS.  BUT
STILL TEMPERATURES WILL FALL A GOOD 10 TO 15 DEGREES BELOW NORMAL.
USED A BLEND OF THE MET/MAV GUIDANCE AND LOWERED A FEW DEGREES FOR
TEMPERATURES THROUGH THE PERIOD.

SATURDAY NIGHT...THE LOW PRESSURE OFF THE CAROLINA COAST WILL MOVE
NORTHEASTWARD PASSING WELL SOUTH OF NANTUCKET LATE.  THE 18Z NAM HAS
THIS LOW PASSING SLIGHTLY MORE TO THE NORTH THAN PREVIOUS MODEL
RUNS.  THIS CLOSER PASS MAY BRING SOME SNOW SHOWERS TO NANTUCKET...
INDICATED BY SLIGHT CHANCE POPS LATE SATURDAY NIGHT.  WILL HAVE TO
KEEP AN EYE ON FUTURE MODEL RUNS TO DETERMINE WHETHER THESE POPS
WILL HAVE TO BE INCREASED.  LOW TEMPERATURES WILL BE SLIGHTLY WARMER
WITH A FEW MORE LOCATIONS ALONG THE SOUTH COAST IN THE DOUBLE
DIGITS...BUT OVERALL ANOTHER CHILLY NIGHT IS IN STORE.

&&

.LONG TERM /SUNDAY THROUGH FRIDAY/...
SATURDAY-SUNDAY...HIGH PRESSURE AND ARCTIC AIR IN CONTROL. MIXING
WILL BE MORE SHALLOW AND LESS FAVORABLE BOTH DAYS SO WINDS SHOULD
ONLY GUST TO 20 KNOTS OR LESS...MOSTLY LESS. CAROLINA LOW PRESSURE
REMAINS WELL OUT TO SEA WITH THE RH FIELDS SHOWING MAINLY A CIRRUS
CANOPY OVER THE REGION SATURDAY ESPECIALLY SOUTH OF THE MASS PIKE.
SOME LOW CLOUDS ASSOCIATED WITH AN APPROACHING COLD FRONT MAY MOVE
INTO THE NORTH AND WESTERN AREAS ON SUNDAY.

BUT IF THERE IS A WEATHER MAKER OVER THE WEEKEND IT WILL BE THE FLOW
OF ARCTIC AIR OVER THE COASTAL WATERS. OCEAN TEMPS EAST OF MASSACHUSETTS
ARE AROUND 40F/4.5C. THE DIFFERENTIAL TO 850 MB TEMPS WILL BE 17-20C
ON SATURDAY AND MAYBE A SMIDGE LESS ON SUNDAY. WINDS OVER MASS BAY
WILL BE 15-20 KNOTS SATURDAY AND AROUND 12-15 KNOTS SUNDAY. POTENTIAL
LIMITING FACTOR WILL BE THE DEPTH OF THE CAPPING INVERSION...WHICH
MAY BE TOO LOW. IDEAL DEPTH IS AROUND 3000-4000 FEET. BUFKIT FORECAST
SOUNDINGS SHOW A DEPTH OF 2000 FEET SATURDAY POSSIBLY INCREASING TO
3000 FEET SUNDAY. AS TO AFFECTED AREAS...WITH A WEST-NORTHWEST WIND
THE BANDS WOULD MAINLY BE OFFSHORE OF OUTER CAPE COD. A NORTH WIND
WOULD BRING SNOW BANDS TO MUCH OF CAPE COD ESPECIALLY FROM MID CAPE
EASTWARD. THE PASSAGE OF THE OFFSHORE LOW BRIEFLY BRINGS WINDS TO
NORTH SATURDAY NIGHT/SUNDAY MORNING...WINDS THEN SHIFT TO WEST SUNDAY
AFTERNOON. THE 00Z ECMWF...SIMILAR TO LAST NIGHT...FORECASTS LIGHT
PRECIP JUST EAST OF OUTER CAPE COD. THEREFORE...WE WILL BRING CHANCE
POPS TO THE CAPE AND ISLANDS SATURDAY NIGHT AND SUNDAY MORNING.
OTHERWISE ANY SNOW SHOWERS WILL STAY JUST OFFSHORE WITH THE FISH.

ALL TEMPS ARE BASED ON A BLEND OF METNAM GRIDS AND GMOS GRIDS.

SUNDAY NIGHT-MONDAY...A WEAK FRONT MOVES THROUGH LATE SUNDAY NIGHT
AND MONDAY MORNING. THIS IS DRIVEN BY A SHORTWAVE MOVING ACROSS FROM
THE GREAT LAKES. LIMITED MOISTURE AND UPPER SUPPORT SO WE WILL BRING
A PERIOD OF CLOUDS LATE NIGHT MOVING OUT MONDAY MORNING. HIGH
PRESSURE BRINGS DRY WEATHER FOR MONDAY AND MONDAY NIGHT.

TUESDAY-WEDNESDAY...LOW PRESSURE FORM THE GREAT LAKES MOVES SOUTH OF
NEW ENGLAND TUESDAY NIGHT-WEDNESDAY. THE ECMWF HAS A BETTER DEFINED
LOW PASSING BY...WHILE THE GFS MOVES AN UPPER SHORTWAVE OVER A WEAK
ZONE IN THE SURFACE HIGH PRESSURE. FOR NOW WE WILL BRING PARTLY
CLOUDY SKIES AND EITHER SLIGHT CHANCE OR LOW-END CHANCE POPS THIS
PERIOD. LOW CONFIDENCE ON ANY PRECIP AND ITS TIMING.

THURSDAY...HIGH PRESSURE BRINGS FAIR WEATHER.

&&

WEATHER WARNING IS IN EFFECT THROUGH 6 PM FOR BOS.

TONIGHT...HIGH CONFIDENCE VFR. W-NW WINDS 25-35 KT EARLY...THEN
