AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE TAUNTON MA
455 PM EDT WED AUG 10 2011
.SYNOPSIS...
A COLD FRONT WILL PUSH ACROSS THE REGION THIS EVENING...BRINGING
SCATTERED SHOWERS AND THUNDERSTORMS. HIGH PRESSURE WILL BRING DRY
AND PLEASANT WEATHER THURSDAY INTO SATURDAY. A COMPLEX WEATHER
SYSTEM MAY TRY TO RIDE UP THE EASTERN SEABOARD SUNDAY...POSSIBLY
BRINGING LOW PRESSURE TOWARD THE REGION MONDAY.
&&
.NEAR TERM /UNTIL 6 AM THURSDAY MORNING/...
STARTING TO SEE SPOTTY CONVECTION DEVELOP ACROSS THE CENTRAL CT
VALLEY AT 20Z HEADING E. OTHERWISE...MAINLY MOSTLY SUNNY SKIES
THROUGH MOST OF THE REGION...WITH OCCASIONAL CLOUDINESS LINGERING
ALONG THE E COAST ALONG WITH ONSHORE WINDS.
SHORT RANGE MODELS SHOWING A RATHER STRONG H5 SHORT WAVE MOVING E
OUT OF THE EASTERN LAKES EARLY TONIGHT. ONLY PROBLEM NOTED IS THE
TIMING OF THIS SYSTEM. SOME CONVECTION POPPING ACROSS E NY STATE
WHICH WILL SHIFT E...BUT THE MAIN ACTION MAY HOLD OFF UNTIL AFTER
02Z. NAM 12KM MODEL SHOWING MAIN SHORT WAVE MOVING IN AROUND 04Z.
BEST INSTABILITY AND SHEAR ACROSS THE REGION...BUT NO LIFT TO SPEAK
OF UNTIL THE SHORT WAVE ARRIVES.
NOTING CAPES AROUND 1000-1500 J/KG ACROSS CENTRAL AND WESTERN MA/N
CT/N RI WHERE A COUPLE OF CELLS HAVE DEVELOPED. ALSO...NOTING BULK
SHEAR FROM THE W-SW AT 35-40 KT...SO PRETTY GOOD INSTABILITY IN
PLACE. SOMEWHAT LOW PW/S...AROUND 1 TO 1.3 INCHES...BUT STILL COULD
SEE SOME BRIEF HEAVY DOWNPOURS WITH ANY SHOWERS OR STORMS.
ALSO CONTINUE TO SEE WEAK BACK DOOR COOL FRONT THAT WORKED ACROSS E
MA...GENERALLY RUNNING W OF KLWM-NEAR KBED-W OF KPYM WITH LIGHT E-NE
WINDS. ALSO NOTING FRONT ON THE EASTERN EDGE OF GROUND CLUTTER
PATTERN ON KBOX 88D. IF ANY CONVECTION DOES MAKE IT FAR ENOUGH
E...THIS COULD BE A FOCUS TO REIGNITE SHOWERS OR STORMS.
BIG QUESTION NOW WILL BE TIMING OF SHORT WAVE AND ANY PRECIP WITH
IT. WILL BE MONITORING CLOSELY.
DOES APPEAR THAT ANY CONVECTION MAY FALL APART AS IT SHIFTS E INTO
MORE STABLE AIRMASS ACROSS E MA...POSSIBLY AROUND OR AFTER 06Z.
SHORT WAVE CONTINUES TO MOVE THROUGH...PUSHING OFF THE COAST BY 12Z.
COOLER AND DRIER AIR WILL ARRIVE W WINDS. EXPECT SKIES TO BECOME
PARTLY CLOUDY AND TEMPS TO FALL BACK TO THE MID AND UPPER 50S ACROSS
THE HIGHER TERRAIN OF S NH/W MA...RANGING TO THE LOWER-MID 60S ALONG
THE IMMEDIATE COAST.
&&
.SHORT TERM /6 AM THURSDAY MORNING THROUGH THURSDAY NIGHT/...
THURSDAY...
LARGE HIGH PRES ACROSS THE OHIO VALLEY WILL BRING MOSTLY SUNNY SKIES
AND DRY...SEASONABLE CONDITIONS. EXPECT SOME DIURNAL CLOUDS DEVELOP
WELL INLAND...BUT WILL BE A VERY PLEASANT DAY. DEWPTS WILL CONTINUE
TO FALL THROUGH THE 50S DURING THE DAY.
EXPECT DAYTIME HIGHS IN THE MID 70S TO LOWER 80S.
THURSDAY NIGHT...
THE HIGH WILL CONTINUE TO SLOWLY SETTLE TOWARD THE REGION...SO
EXPECT LIGHT WINDS AND MOSTLY CLEAR SKIES. LOWS WILL DROP THROUGH
THE 50S...AND COULD EVEN SEE SOME READINGS DROP TO THE UPPER 40S
ACROSS THE HIGHER TERRAIN WELL INLAND...RANGING TO THE LOWER 60S
ALONG THE IMMEDIATE COAST.
&&
.LONG TERM /FRIDAY THROUGH WEDNESDAY/...
HIGHLIGHTS...
* DRY AND PLEASANT WEATHER EXPECTED FRI INTO AT LEAST SAT AFTERNOON
* HEAVY SHOWERS LIKELY SOMETIME SUN POSSIBLY EXTENDING INTO MON.
DETAILS...
FRIDAY TO SATURDAY...
A FEW PLEASANT WEATHER DAYS WILL BE ON TAP FOR BOTH FRIDAY AND
SATURDAY AS HIGH PRESSURE BUILDS EASTWARDS AND SPREADS ACROSS
SOUTHERN NEW ENGLAND. THIS WILL RESULT IN MOSTLY SUNNY SKIES AND MAX
TEMPERATURES IN THE UPPER 70S TO LOWER 80S ACROSS THE REGION. CLOUDS
WILL BEGIN TO INCREASE THROUGHOUT THE DAY ON SATURDAY AS HIGH
PRESSURE CONTINUES TO MOVE EASTWARD OFF THE COAST COMBINED WITH
THE NEXT SYSTEM APPROACHING.
SUNDAY TO WEDNESDAY...
THIS IS THE MAIN FOCUS FOR THE EXTENDED AS THE GFS/ECMWF/GEM ALL
POINT TOWARDS A HEAVY RAIN PRODUCER ACROSS THE AREA. A VERY STRONG
SHORTWAVE FOR THIS TIME OF YEAR WILL MOVE ACROSS THE GREAT LAKES ON
SUNDAY. IN RESPONSE...A SURFACE LOW WILL DEVELOP AND TREK ACROSS THE
NEW ENGLAND COAST. WITH THE STRONG DYNAMICS IN THIS SYSTEM AND PWAT
VALUES NEARING 2 INCHES...CONFIDENCE IS HIGH THAT THE AREA WILL SEE
SOME RAIN BEGINNING SUNDAY AND LASTING TIL AT LEAST MONDAY EVENING
WITH THE HEAVIER RAIN OCCURRING ON SUNDAY NIGHT. THERE IS A CHANCE
THAT LOW CLOUDS AND SHOWERS MAY LINGER BEHIND THE SYSTEM THROUGH
TUESDAY AND WEDNESDAY AS MODELS HAVE BEEN IN DISAGREEMENT ON THE
MOVEMENT AND AMPLIFICATION OF THE UPPER LOW/SHORT WAVE OVER NEW
ENGLAND. DECIDED TO BE MORE CONSERVATIVE AND KEPT A SLIGHT CHANGE OF
POPS IN FOR TUESDAY AND KEEP WEDNESDAY DRY FOR NOW. WILL NEED TO
CONTINUE TO MONITOR THIS POTENTIAL SYSTEM ESPECIALLY FOR SUNDAY
NIGHT FOR HYDROLOGY CONCERNS.
&&

ACROSS THE REGION...WITH LOW CHANCE OF HITTING SPECIFIC TERMINAL
SITES. COULD SEE LOCAL BRIEF HEAVY DOWNPOURS...GUSTY WINDS AND
POSSIBLE HAIL WITH MVFR-IFR CONDITIONS.
TONIGHT...
MODERATE CONFIDENCE. LOOKS LIKE SCT SHOWERS/TSTMS WILL PUSH ACROSS
MA/S NH...WITH LOW CHANCE REACHING INTO N CT/RI...THROUGH 04Z-05Z.
MAINLY VFR...BUT WILL SEE BRIEF PERIODS OF MVFR-IFR CIGS/VSBYS IN
ANY PRECIP. WINDS SHIFT TO W-NW AFTER MIDNIGHT WITH DRIER AIR

TONIGHT...
SEAS CONTINUE TO RUN AROUND 5 FT ACROSS THE OUTER WATERS THIS
AFTERNOON...WITH 7 FOOT SEAS REPORTED ON THE GULF OF MAINE. E-NE
WINDS CONTINUE AT 20Z...MAINLY TO THE E OF THE WATERS...SO HAVE
EXTENDED THE SMALL CRAFT FOR HAZARDOUS SEAS THROUGH MIDNIGHT. LOW
CONFIDENCE ON TIMING WHEN THE SEAS WILL SUBSIDE...BUT WILL MONITOR
CLOSELY TO EITHER EXTEND OR POSSIBLY END EARLY.
OTHERWISE...EXPECT N-NE WINDS ACROSS THE EASTERN WATERS TO DIMINISH
AND SHIFT TO W DURING THE NIGHT. SCATTERED SHOWERS/TSTMS WILL
APPROACH THE EASTERN WATERS THIS EVENING.
THURSDAY AND THURSDAY NIGHT...EXPECT LIGHT W WINDS AND SEAS BELOW
SMALL CRAFT CRITERIA.
OUTLOOK...FRIDAY THROUGH MONDAY...
FRIDAY THROUGH SATURDAY...
HIGH PRESSURE WILL BE BUILDING IN FROM THE WEST ALLOWING FOR BOTH
SEAS AND WIND TO BE BELOW SMALL CRAFT ADV. ALTHOUGH ON
SATURDAY...WITH THE SOUTHWEST FLOW...THE WIND MAY GUSTS UP TO 15 KTS
ALONG THE SOUTH COAST.
SUNDAY THROUGH MONDAY...
WITH THE APPROACHING DYNAMICAL SYSTEM...EXPECT WINDS TO GUSTS UP TO
25 KTS WITH SEAS REACHING 5 TO 8 FT. THEREFORE CONFIDENCE IS HIGH
