AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE TAUNTON MA
430 PM EDT SAT MAY 7 2011

.SYNOPSIS...
AN UPPER LEVEL DISTURBANCE WILL MOVE ACROSS NEW ENGLAND THIS EVENING
THEN STALL EAST OF NEW ENGLAND OVERNIGHT AND SUNDAY. AN OCEAN STORM
WELL OFFSHORE WILL DRIFT BACK TOWARD THE COAST AND BRING CLOUDS...
GUSTY ONSHORE WINDS AND COOL TEMPERATURES ESPECIALLY TO EASTERN NEW
ENGLAND THROUGH THE MIDDLE OF NEXT WEEK. SOME IMPROVEMENT IS
EXPECTED TOWARD THE END OF THE WEEK.

&&

.NEAR TERM /UNTIL 6 AM SUNDAY MORNING/...
AS OF 3 PM...CONVECTION IS WEAKENING ACROSS SNE AS SBCAPES HAVE
DECREASED. SCT SHOWERS AND ISOLD THUNDER PERSISTS BUT INTENSITY
HAS DECREASED CONSIDERABLY. MID LEVEL TROF STILL BACK TO THE
WEST AND WILL BE MOVING INTO SNE THIS EVENING THEN E OF NEW ENG
LATE TONIGHT.

REGIONAL RADAR SHOWS SCT SHOWERS EXTENDING BACK INTO NEW YORK AND
PA. WHILE SOME OF THIS ACTIVITY WILL DISSIPATE THROUGH THIS
EVENING...WE CANT RULE OUT A FEW SHOWERS OR EVEN AN ISOLD TSTM
THIS EVENING AS THE MID LEVEL TROF AND ASSOCD COLD POOL /-25C AT
500 MB/ MOVES THROUGH. TT VALUES STILL RATHER IMPRESSIVE WITH AREA
OF MID 50S TT MOVING THROUGH 00-06Z FROM WEST TO EAST THEN E OF
NEW ENG BY 12Z...AND ENOUGH MOISTURE IN THE COLUMN TO SUPPORT CHC
POPS TONIGHT.

&&

.SHORT TERM /6 AM SUNDAY MORNING THROUGH SUNDAY NIGHT/...
SUNDAY...MID LEVEL LOW MEANDERS E OF NEW ENG WITH OCEAN STORM WELL
OFFSHORE. OCEAN LOW CLOUDS EXPECTED TO REMAIN TO THE EAST...BUT RH
PROFILES SHOW ENOUGH MOISTURE IN THE COLUMN FOR MOCLDY SKIES
ESPECIALLY E NEW ENG CLOSEST TO MID LEVEL LOW.

LESS INSTABILITY EXPECTED COMPARED TO TODAY BUT MODELS SHOW
ANOTHER SPIKE IN TT TO LOWER 50S IN THE INTERIOR WITH SUBTLE LOW
LEVEL THETA-E RIDGE DEVELOPING. WILL ADVERTISE CHC POPS FOR THE
INTERIOR BUT NO THUNDER AS SFC INSTABILITY IS NEAR NIL.

N/NE FLOW DEVELOPS WHICH WILL RESULT IN COOLEST TEMPS ACROSS E
COASTAL MA AND MILDEST READINGS IN THE CT VALLEY.

SUNDAY NIGHT...OCEAN STORM RETROGRADES AND WILL LIKELY RESULT IN
LOW CLOUDS BACKING IN TOWARD THE COAST AS NE FLOW INCREASES WITH
LOW PROB FOR A FEW SHOWERS REACHING CAPE/ISLANDS LATE.

&&

.LONG TERM /MONDAY THROUGH SATURDAY/...
HIGHLIGHTS...
***CUTOFF LOW OFFSHORE WILL BRING SIGNIFICANT WINDS AND SWELLS TO
COASTAL REGION***

MAIN FEATURE OF INTEREST FOR THE LONG TERM IS A CUTOFF LOW THAT
FORMS TO THE EAST OF NEW ENGLAND. ALL MED RANGE MODELS SHOW THIS
FEATURE BUT THERE ARE SOME DIFFERENCES IN INTENSITY AND LOCATION.
THERE IS REASONABLY GOOD CLUSTERING IN THE GFS ENSEMBLES WITH
LOCATION...ALBEIT INTENSITY VARIATIONS. THIS CUTOFF WILL LIKELY BE
CLOSE ENOUGH TO ROTATE CONSIDERABLE STRATOCUMULUS CLOUDS INTO
EASTERN MA AND RI DURING MON INTO TUE. THE CT VALLEY WILL LIKELY
REMAIN JUST PARTLY CLOUDY THRU THE PERIOD. LESS CONFIDENT ON RAIN
CHANCES. HAVE INCREASED POPS TO CHANCE ALONG IMMEDIATE MA COAST AND
SLIGHT CHANCE AS FAR WEST AS AFN TO ORH TO WST LINE. SREF OUTPUT
PLACES HI CHANCE FOR .01 OR GREATER OUTER CAPE AND ACK. SEE A RISK
OF A MID LEVEL DEFORMATION ZONE THAT COULD RESULT IN A BAND OF MORE
SIGNIFICANT MEASURABLE RAIN ACROSS EASTERN OR CENTRAL ZONES...BUT
CONFIDENCE IN THIS MATERIALIZING AND WHERE IF IT DOES MATERIALIZE IS
LOW.

THE OTHER SENSIBLE WEATHER IMPACT FROM THE CUTOFF LOW IS POTENTIAL
FOR WIND GUSTS BETWEEN 30 AND 40 MPH ACROSS MUCH OF EASTERN MA AND
AT LEAST PARTS OF RI LATE MON INTO TUE. THERE IS EVEN A SLIGHT RISK
OF ADVISORY LEVEL WINDS BEING REACHED ALONG THE OUTER CAPE AND ACK.

THE PERIOD FROM TUE NIGHT THROUGH THU MORNING LOOKS DRY WITH PARTLY
CLOUDY/MOSTLY CLEAR SKIES AS REGION BECOMES SITUATED IN A NARROW
RIDGE BETWEEN THE CLOSED LOW SLOWLY LIFTING OUT OF THE CENTRAL USA
AND THE WEAKENING CUTOFF OFFSHORE. BY THU AFTERNOON CLOUDS WILL
LIKELY INCREASE AS ENERGY FROM THE CENTRAL PART OF THE COUNTRY
APPROACHES. HAVE A CHANCE OF RAIN THU NIGHT THROUGH FRI NIGHT. THIS
SYSTEM MAY FEATURE A WAVE OF LOW PRESSURE ALONG THE FRONT BUT
CONFIDENCE IN DETAILS IS NOT VERY HIGH THIS FAR OUT. AS IS OFTEN THE
CASE...THE GFS APPEARS TO BE FASTER THAN THE ECMWF.

WENT WITH BIAS CORRECTED MOS GUIDANCE FOR THE LONGER TERM PERIOD.
TEMP RANGE IS LIKELY TO BE FAIRLY NARROW IN NORTHEAST FLOW MON
THROUGH TUE.

&&

.AVIATION /21Z SATURDAY THROUGH THURSDAY/...
FORECASTER CONFIDENCE LEVELS...
  LOW...LESS THAN 30 PERCENT
  MODERATE...30 PERCENT TO 60 PERCENT
  HIGH...GREATER THAN 60 PERCENT

THROUGH 00Z...SCT CONVECTION WILL BE FOCUSED E OF CT VALLEY THIS
AFTERNOON WITH MVFR CONDITIONS LIKELY IN ANY SHOWERS/TSTMS ALONG
WITH SMALL HAIL. OTHERWISE VFR WILL PREVAIL.

TONIGHT...SCT SHOWERS MAY PERSIST ACROSS E NEW ENG DURING THE
EVENING...OTHERWISE VFR CIGS AOA 080 LIKELY. MEDIUM TO HIGH
CONFIDENCE.

SUNDAY...VFR CIGS EXPECTED...BUT SCT SHOWERS EXPECTED TO DEVELOP
IN THE AFTERNOON. LOW PROB FOR MVFR CIGS DEVELOPING OVER THE OUTER
CAPE IN THE AFTERNOON AS CLOUDS BACK IN FROM THE OCEAN IN NE FLOW.

SUNDAY NIGHT...MAINLY VFR CIGS BUT MVFR CIGS MAY EXPAND ACROSS
EASTERN NEW ENG.

KBOS TERMINAL...SHOWERS SHOULD MOVE OUT OF LOGAN AIRPORT
20-21Z..BUT CANT RULE OUT ADDITIONAL SHOWERS THROUGH THIS
EVENING. CONFIDENCE IS MUCH LOWER ON SEABREEZE DEVELOPMENT DUE TO
OUTFLOW WINDS SO REMOVED FROM TAF. VFR CIGS EXPECTED THROUGH THE
TAF PERIOD. NE WINDS SUNDAY.

OUTLOOK...MONDAY THROUGH THURSDAY...

MONDAY THROUGH TUESDAY...HIGH CONFIDENCE FOR VFR CONDITIONS ACROSS
THE CT VALLEY INTO SW NH. MEDIUM CONFIDENCE FOR MVFR CIGS CENTRAL
AND EASTERN AREAS. NE WINDS MAY GUST TO 30 KT ALONG THE E COAST
MAINLY DURING THE DAYLIGHT HOURS.

WEDNESDAY...MEDIUM TO HIGH CONFIDENCE FOR VFR MAINLY FROM KAFN-KIJD
LINE WEST. LOW TO MEDIUM CONFIDENCE FOR AREAS OF MVFR CIGS E OF
KAFN-KIJD LINE...BEST SHOT FOR MVFR CIGS ALONG E COAST. NE WIND
GUSTS UP TO 25-30 KT ALONG E COAST POSSIBLE.

THURSDAY...MEDIUM CONFIDENCE FOR VFR CONDITIONS.

&&

.MARINE...
TONIGHT...WINDS BECOMING NW BEHIND SFC TROF BUT SPEEDS BELOW SCA.
SEAS UP TO 5 FT OVER OUTER WATERS SUBSIDING OVERNIGHT.

SUNDAY...N/NE WINDS DEVELOPING WITH GUSTS UP TO 20 KT. SEAS BELOW
SCA.

SUNDAY NIGHT...NORTHERLY WINDS INCREASE AS OCEAN STORM RETROGRADES
WITH GUSTS UP TO 25 KT DEVELOPING LATE OVER EASTERN WATERS. SEAS
GRADUALLY BUILD REACHING SCA THRESHOLDS.

OUTLOOK...MONDAY THROUGH THURSDAY...

MONDAY-TUESDAY...EXPECT INCREASING NE GRADIENT AS OFFSHORE LOW
STARTS TO BACK TOWARD THE OUTER CAPE AND NANTUCKET AS IT
INTENSIFIES...BUT SHOULD REMAIN WELL SE. MEDIUM CONFIDENCE FOR GALE
FORCE NE WINDS OVER THE EASTERN WATERS OF STELLWAGEN BANK DOWN TO E
AND S OF THE CAPE. EXPECT NE WINDS TO CONTINUE...WHICH WILL CREATE A
LONG NE FETCH ACROSS THE EASTERN OUTER WATERS. HAVE CONTINUED TREND
FROM PREVIOUS FORECAST AND INCREASED SEAS ESPECIALLY OVER THE
EASTERN WATERS BY 1-2 FEET FROM THE WNA WAVEWATCH MODEL...AS THIS
MODEL DOES NOT HANDLE THE LONG NE FETCH TOO WELL. WILL LIKELY SEE A
STORM SURGE OF 1 TO 1.5 FEET THROUGH THIS PERIOD. ASTRO TIDES
FORECAST TO RUN SOMEWHAT LOW...THOUGH SOMETHING TO WATCH ALONG THE E
COAST.

WEDNESDAY...MAY STILL SEE NE WINDS TO GALE FORCE OVER THE EASTERN
WATERS WITH SMALL CRAFT LEVEL CONDITIONS ELSEWHERE. SEAS MAY START
TO SLOWLY SUBSIDE BUT REMAIN WELL ABOVE 5 FT ON THE OPEN WATERS.

THURSDAY...LOW PROBABILITY OF GALE FORCE WIND GUSTS S AND E OF CAPE
COD AND NANTUCKET EARLY...THEN SHOULD DIMINISH BUT REMAIN ABOVE
SMALL CRAFT.
