A strong low level jet moved across the Cape and Islands and continuing rainfall allowed these winds to mix to the surface. High winds were experienced mainly on the outer cape with a station at Wellfleet measuring 40 mph sustained winds.

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE TAUNTON MA
215 PM EDT THU NOV 4 2010
.SYNOPSIS...
LOW PRESSURE DEVELOPING ALONG THE MID ATLANTIC COAST WILL MOVE
NORTHEAST TO NEAR LONG ISLAND THIS EVENING...WITH A WARM FRONT
LIFTING NORTH ALONG THE COAST LATER TODAY AND TONIGHT. A SECOND LOW
WILL DEVELOP OFF THE MID ATLANTIC COAST TONIGHT AND MOVE INTO THE
GULF OF MAINE FRIDAY EVENING. THIS STORM MEANDERS ABOUT SOUTHEAST
CANADA SATURDAY...THEN HIGH PRESSURE WILL BUILD IN FROM THE
SOUTHEAST UNITED STATES FOR SUNDAY INTO THE MIDDLE OF NEXT WEEK.
&&
.NEAR TERM /UNTIL 6 PM THIS EVENING/...
NOT MUCH CHANGE FROM PREVIOUS FORECAST. STRONG EAST-SOUTHEAST
WINDS CONTINUE FOR THE CAPE AND ISLANDS THROUGH 5 PM WITH WINDS
DIMINISHING BETWEEN 7-8 PM. PEAK WINDS SO FAR...ACK 36KT/MVY 33 KT
AND WELLFLEET 39 KT.
RAIN WILL BEGIN TO EASE LATER THIS AFTERNOON AND EARLY EVENING AS
LOW LEVEL JET RACES NORTHEAST INTO THE GULF OF MAINE. ALREADY
STARTING TO SEE THIS ON UPSTREAM RADARS WITH LACK OF RADAR ECHOES
SOUTH OF NEW ENGLAND. SO FAR RAINFALL AMOUNTS HAVE RANGED FROM
0.20-0.65 INCHES ACROSS THE REGION AT 18Z.
WARM SECTOR APPROACHING MVY AND ACK WITH WIND SHIFTING TO
SOUTHEAST. TEMPS SHOULD JUMP THROUGH THE 50S TO NEAR 60 ACROSS
SOUTHEAST MA LATER TODAY.
&&
.SHORT TERM /6 PM THIS EVENING THROUGH 6 AM FRIDAY/...
MID LEVEL TROF UNDERGOES FURTHER AMPLIFICATION TONIGHT AS IT DIGS
INTO THE SE US. ADDITIONAL UPSTREAM ENERGY AND HEIGHT FALL CENTER
WILL RESULT IN A SECOND COASTAL LOW DEVELOPING ALONG MID ATLC
COAST WHICH MAY END UP CONSOLIDATING WITH FIRST LOW OVER SE NEW ENG
LATE TONIGHT. WILL SEE ANOTHER PULSE OF RAIN TONIGHT...AND THIS
TIME THE HEAVIER RAIN SHOULD BE FOCUSED IN SE NEW ENG ASSOCD WITH
SOUTHERLY LLJ WHICH PASSES CLOSE TO THE CAPE/ISLANDS. ISOLD THUNDER
ALSO POSSIBLE ACROSS SE NEW ENG NEAR THE LLJ AS ELEVATED INSTABILITY
PARAMETERS ARE FAVORABLE.
06Z NAM HAS SHIFTED FURTHER EAST WITH THE LLJ BUT IS STILL ON THE
WESTERN EDGE OF THE GUIDANCE. NAM WOULD SUPPORT STRONG WINDS OVER
THE CAPE/ISLANDS LATE TONIGHT WITH POTENTIAL FOR WIND ADVSY WHILE
REST OF THE MODEL GUIDANCE KEEPS THE STRONGEST WINDS OFFSHORE. WE
STILL EXPECT A PERIOD OF GUSTY SOUTHERLY WINDS LATE TONIGHT OVER
CAPE/ISLANDS BUT LOW LEVEL INVERSION WILL LIMIT THE GUST POTENTIAL.
WARM FRONT WILL LIFT NWD ALONG THE EASTERN NEW ENG COAST TONIGHT
WITH RISING TEMPS EXPECTED IN THE COASTAL PLAIN. TEMPERATURES MAY
RISE INTO THE 60S FOR A TIME OVER INTERIOR SE MA BUT COOLER
IMMEDIATE S COAST AND CAPE/ISLANDS DUE TO SOUTHERLY FLOW. WEST OF
THE FRONT IN THE INTERIOR TEMPS WILL HOLD IN THE 40S.
&&
.LONG TERM /FRIDAY THROUGH WEDNESDAY/...
IN THE LARGER PICTURE...A HIGH AMPLITUDE TROF MOVES THROUGH FOLLOWED
BY A LARGE BROAD RIDGE FOR NEXT WEEK. FORECAST CALLS FOR DRYING
CONDITIONS FRIDAY AND NIGHT...AND THEN DRY FOR THE REST OF THE
WEEKEND THROUGH AT LEAST MID WEEK. THERE IS...HOWEVER...A POTENTIAL
FLY IN THE OINTMENT. THE 00Z ECMWF...FOLLOWING A THEME FROM THE 18Z
GFS RUN...CLOSES OFF THE EXITING UPPER LOW AND RETROGRADES A SURFACE
LOW S OF NOVA SCOTIA INTO THE EASTERN GULF OF MAINE EARLY NEXT WEEK.
THIS COULD BRING CLOUDS BACK INTO EASTERN AREAS LATE MON THRU
TUE...AND POSSIBLY EVEN BRING A THREAT OF RAIN FOR EAST COASTAL
AREAS. THE GFS ENSEMBLES DO DEPICT THREE MEMBERS SIMILAR TO THE
LATEST ECMWF SOLUTION.
A LITTLE MORE SPECIFICALLY...
FRIDAY AND FRIDAY NIGHT...EXPECT STEADY RAFL TO TAPER OFF SW TO NE
DURING THE MORNING. SINCE THE UPPER LOW IS SO AMPLIFIED WITH THE
AXIS STILL WELL W OF NEW ENGLAND...A LITTLE WARY OF GETTING
STRAIGHTFORWARD CLEARING. THUS DECREASED POPS AND CLOUD COVER RATHER
SLOWLY. KEPT CHANCE POPS NEAR THE BERKSHIRE CREST AND MONADNOCKS FRI
NIGHT DUE TO OROGRAPHY. ANY RAIN COULD MIX OR CHANGE TO WET
SNOW...BUT NO ACCUMULATION OF ANY CONSEQUENCE EXPECTED. MODERATELY
STRONG COLD AIR ADVECTION SETS IN OVERNIGHT.
SATURDAY THRU SUNDAY...EVEN THOUGH THE UPPER TROF AXIS DOES NOT PASS
OUR LONGITUDE UNTIL SUNDAY MORNING...MODELS DEPICT VERY DRY AIR.
THUS...KEPT POPS LOW WITH JUST SLIGHT CHANCE OVER THE BERKSHIRES AND
MONADNOCKS WHERE COULD NOT RULE OUT A FLURRY OR SPRINKLE DUE TO COLD
POOL ALOFT AND THE OROGRAPHY. PROBABLY TEMPS IN 20S AND 30S SATURDAY
NIGHT. STAYED CLOSE TO MOSGUIDE FOR SAT AND SUN. HIGHS SAT SHOULD
GENERALLY RANGE FROM UPPER 40S NW TO LOWER 50S SE. SUN IS LIKELY TO
BE STILL A LITTLE COOLER WITH HIGHS REMAINING IN THE 40S MOST
LOCATIONS...PERHAPS NOT GETTING ABOVE THE LOWER TO MID 40S ACROSS
THE NW HIGHER TERRAIN.
EARLY NEXT WEEK...AS ALREADY NOTED...THIS PART OF THE FORECAST MAY
NOT BE QUITE AS CLEAR CUT AS WOULD FIRST SEEM. FOR NOW HAVE LEANED
TOWARD THE GREATER MODEL CONSENSUS OF DRY CONDITIONS EVERYWHERE AND
JUST SOME CLOUDINESS BACKING NEAR THE COAST. HOWEVER...THIS IS A
LARGE AMPLITUDE TROF WITH AN ASSOCIATED STRONG BAROCLINIC ZONE.
THUS...WOULD NOT BE SURPRISED IF IT TAKES LONGER TO FULLY EXIT LATER
THAN ADVERTISED AND HOLD BACK THE UPSTREAM RIDGE FROM BUILDING INTO
THE REGION FOR A DAY OR TWO. MAIN CONCERN IS EAST COASTAL SOUTHERN
NEW ENGLAND WHERE AN ALTERNATE FORECAST SCENARIO WOULD INCLUDE MORE
CLOUDS AND A CHANCE OF SOME RAIN LATE MON THRU TUE.
&&
.AVIATION /18Z THURSDAY THROUGH TUESDAY/...
THIS AFTERNOON AND EVENING...
MAINLY IFR CIGS WITH MVFR VSBYS. RAIN WILL TAPER OFF LATE THIS
AFTERNOON AND EARLY EVENING. LLWS CONFINED TO RI AND SOUTHEAST MA.
CONFIDENCE OVERALL MODERATE TO HIGH.
OVERNIGHT...
MORE OF THE SAME IFR CIGS WITH MVFR VSBYS. RAIN WILL REDEVELOP
ACROSS THE REGION AROUND MIDNIGHT FROM SOUTH TO NORTH AND THEN
TAPER OFF TO DRIZZLE TOWARD 09Z-12Z. LLWS IN STRONG SOUTH WINDS
ALOFT WILL OCCUR ACROSS CAPE COD AND THE ISLANDS. CONFIDENCE IS
ONLY AVERAGE AS CIGS AND VSBYS MAY LOWER TO LIFR FROM TIME TO TIME.
FRIDAY...
IFR CIGS WITH MVFR VSBYS WILL GRADUALLY IMPROVE TO VFR DURING THE
AFTERNOON FROM WEST TO EAST. RAIN ACROSS EASTERN MA WILL END BY
MIDDAY WITH DRY RUNWAYS FROM THE AFTERNOON. CONFIDENCE IS LOW ON
THE TIMING OF IMPROVING CONDITIONS.
KBOS TERMINAL...
IFR CIGS AND MVFR VSBYS MOST LIKELY SCENARIO FOR REMAINDER OF THIS
AFTERNOON AND CONTINUING INTO TONIGHT. LOW PROBABILITY OF LIFR
CONDITIONS OVERNIGHT ALTHOUGH WILL GO WITH IFR CIGS AND MVFR VSBYS
IN TAF GIVEN THIS IS THE MOST LIKELY SCENARIO. LLWS SHOULD BE
CONFINED TO CAPE COD AND THE ISLANDS. RAIN WILL TAPER OFF LATE
THIS AFTERNOON AND EARLY EVENING BEFORE REDEVELOPING AROUND
MIDNIGHT. CONDITIONS IMPROVE TO VFR FRI AFTN ALONG WITH DRY RUNWAYS.
OUTLOOK...FRIDAY NIGHT THROUGH MONDAY...
FRI NIGHT...MODERATE TO HIGH CONFIDENCE OF MOSTLY VFR CONDITIONS.
PATCHY MVFR CIGS ARE POSSIBLE IN SCATTERED RAIN/SNOW SHOWERS OVER
BERKSHIRES AND MONADNOCKS.
SAT THRU MON...MODERATE TO HIGH CONFIDENCE OF VFR CONDITIONS.
*** CHANGES TO TAF PROGRAM ***
NWS TAUNTON IS NOW ISSUING TAFS FOR HANSCOM FIELD IN BEDFORD MA
/KBED/. IN ADDITION...TAFS FOR WORCESTER MA /KORH/ ARE NOW ISSUED
EVERY 6 HOURS. AMENDMENTS ARE NO LONGER PROVIDED FOR KORH.
&&
.MARINE...
E/SE LLJ LIFTING NWD ACROSS THE WATERS WILL BRING A PERIOD OF GUSTY
WINDS LATER THIS MORNING INTO THE AFTERNOON. WE HAVE SCA ALL WATERS
AND THERE IS A CHANCE FOR A FEW GALE FORCE GUSTS OVER THE EASTERN
WATERS AS STRONG PRES FALLS DEVELOP. WINDS SHIFT TO SOUTH OVER SE
WATERS LATER TODAY AND DIMINISH.
ANOTHER PULSE OF GUSTY SOUTHERLY WINDS EXPECTED TONIGHT ASSOCD WITH
THE SOUTHERLY LLJ. CORE OF THE JET EXPECTED TO PASS OVER EASTERN
MOST WATERS WHERE STRONGEST WINDS EXPECTED. BUT STRONGER LOW LEVEL
INVERSION OVER THE WATER SHOULD KEEP GUSTS BELOW GALE.
OULOOK...FRIDAY THROUGH MONDAY
WILL LIKELY SEE A RATHER EXTENSIVE PERIOD OF GUSTS TO 25 TO 30 KT
LATE FRI THROUGH THE WEEKEND. CONFIDENCE IS ONLY MODERATE AS MODELS
SHOW CONSIDERABLE VARIABILITY IN THE STRENGTH OF THE SURFACE
GRADIENT OVER THE WEEKEND INTO EARLY NEXT WEEK. WILL ALSO HAVE TO
DEAL WITH AN EXTENDED PERIOD OF RATHER ROUGH SEAS IN THE MORE
EXPOSED WATERS...ALTHOUGH ONCE AGAIN THE WNA GUIDANCE LOOKS TO BE
OVERDONE BY SOME 15 TO 20 PERCENT.
&&
.TIDES/COASTAL FLOODING...
ASTRONOMICAL TIDES ARE RUNNING HIGH HOWEVER PERIOD OF STRONGEST
WINDS WILL OCCUR DURING LOW TIDE THIS AFTERNOON. THEREFORE RISK OF
COASTAL FLOODING IS VERY LOW TO NIL.
