AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE TAUNTON MA
952 AM EDT WED OCT 1 2008

.SYNOPSIS...
A COLD FRONT WILL PUSH INTO THE REGION TODAY...BRINGING SOME SHOWERS
AND A FEW RUMBLES OF THUNDER. THIS FRONT WILL PUSH OFF THE COAST BY
EARLY THURSDAY. HIGH PRESSURE WILL PUSH INTO NEW ENGLAND OUT OF
CENTRAL CANADA...BRINGING DRY AND COOLER WEATHER FOR THIS WEEKEND.
THE HIGH WILL REMAIN OVER THE NORTHEAST THROUGH NEXT TUESDAY.

&&

.NEAR TERM /UNTIL 6 PM THIS EVENING/...
NUMEROUS SHOWERS AND ISOLD TSTMS ARE MOVING NORTH ACROSS CT AND INTO
SW MA AT 9 AM WITH TT/SWI/LI INDICATING BEST INSTABILITY IN THIS
REGION. GFS SHOWS THIS INSTABILITY SHIFTING TO NE MA AND SE NH BY 18Z
SO EXPECT SCT SHOWERS AND ISOLD TSTMS TO MOVE NE THROUGH EARLY
AFTERNOON...BUT THEN DRYING MOVES IN FROM THE SW AS NOTED IN KI FIELD
AT 18Z.

CROSS SECTIONS SHOW A THINNING OF THE MOISTURE THIS AFTERNOON WHICH
ARGUES FOR SOME BREAKS OF SUN. VISIBLE SATELLITE SHOWS MOSTLY CLEAR
SKIES SOUTH OF THE COAST WITH BREAKS OVER SE NY AND WHILE THE CLOUDS
SHOULD FILL IN THE CLEAR AREAS...WE DO EXPECT SOME BREAKS OF SUN THIS
AFTERNOON BUT CONTD LOW CHC SHOWERS. GFS INDICATES AREA OF OMEGA
DEVELOPING OVER THE OCEAN THIS AFTERNOON AND MOVING NE POSSIBLY
BRINGING A PERIOD OF SHOWERS/POSSIBLE TSTMS TO OUTER CAPE/ISLANDS LATE
TODAY OR EARLY EVENING. RGEM IS SIMILAR BUT FURTHER OFFSHORE. WE WILL
KEEP POPS IN CHC CATEGORY FOR THE CAPE TODAY AND ILL MONITOR IF ANY
CONVECTION DEVELOPS TO THE SOUTH THIS AFTERNOON FOR POSSIBLE
INCREASE IN POPS.

&&

.SHORT TERM /6 PM THIS EVENING THROUGH 6 PM THURSDAY/...
01/00Z MODELS ARE QUITE CLOSE...AND SEE NO PRESSING REASON TO
DEVIATE TOO MUCH FROM THE CONSENSUS SOLUTION. SHOULD SEE THE OCCLUDED
FRONT REACH THE EAST COAST OF NEW ENGLAND TOWARD 02/00Z. IMPRESSIVE
UPPER LEVEL JET DYNAMICS AND A MID LEVEL SHORTWAVE WILL WARRANT
KEEPING A MENTION OF THUNDERSTORMS INTO TONIGHT ACROSS PORTIONS OF
SOUTHEAST MA AND THE COASTAL WATERS.

ANY THUNDERSTORMS TODAY OR EARLY THIS EVENING COULD PRODUCE BRIEFLY
HEAVY RAINFALL AND/OR SMALL HAIL. DO NOT THINK THE RISK OF HAIL IS
WIDESPREAD ENOUGH TO MENTION IN THE ZONES...BUT WILL MENTION THE
POSSIBILITY OF HEAVY RAINFALL.

TONIGHT...SHORTWAVE MOVES OFF THE COAST AFTER MIDNIGHT...AND WILL
LIKELY RESULT IN A SECONDARY LOW DEVELOPING ALONG THE FRONT OFFSHORE.
THIS WILL SLOW DOWN THE DRYING TREND FROM WEST TO EAST AS THE FRONT
CANNOT MOVE OFFSHORE AS QUICKLY.

THURSDAY...DRIER WEATHER WITH SEASONABLE TEMPERATURES EXPECTED.

&&

.LONG TERM /THURSDAY NIGHT THROUGH TUESDAY/...
MEDIUM RANGE MODELS ARE IN PRETTY GOOD AGREEMENT THIS MORNING. GFS
OP RUN THIS MORNING MORE IN LINE WITH THE MODEL SUITE AS COMPARED TO
YESTERDAYS RUN.

THURSDAY NIGHT THROUGH SUNDAY...UPPER LEVEL CUTOFF LOW WILL
DOMINATE...SLIDING NE OUT OF QUEBEC TO LABRADOR. THIS WILL KEEP THE
REGION IN A CYCLONIC UPPER FLOW OVER THE REGION INTO THIS WEEKEND.
WEAK SHORT WAVES IN THE FLOW MAY THROW IN A FEW MORE CLOUDS...BUT
DRY W-SW FLOW WILL LIMIT ANY SHOWERS.

AS THE LOW MOVES AWAY...E-W ELONGATED SHORT WAVE MAY TRY TO ROTATE
INTO THE REGION SUNDAY. NOT EXPECTING MUCH IN THE WAY OF PRECIP...
BUT HAVE A FEW MORE CLOUDS THAT DAY.

SUNDAY NIGHT...AS THE UPPER SHORT WAVE WORKS ACROSS...WEAK
REFLECTION AT THE SURFACE MIGHT PRODUCE A BRIEF SHOWER OR TWO. HAVE
SLIGHT CHANCE POPS MENTIONED IN THE GRIDS. THIS SYSTEM IS MOISTURE
STARVED THOUGH SO AT THIS POINT EXPECTED LITTLE IF ANY PRECIP.

MONDAY-TUESDAY...SOME MODEL SPREAD WITH EVOLUTION OF SURFACE AND
UPPER LEVEL PATTERN...NAMELY THE 00Z OP ECMWF RUN. THIS MODEL TRIES
TO SPIN UP A WEAK LOW ON THE PASSING FRONT S OF NEW ENGLAND.
HOWEVER...THIS IS AN OUTLIER AS MOST OTHER MODELS SHOWING A LARGE
HIGH BUILDING OUT OF HUDSON BAY. THIS WILL BRING COOLER AND DRY
WEATHER FOR EARLY NEXT WEEK.

&&

.AVIATION /13Z WEDNESDAY THROUGH SUNDAY/...
A MIX OF MVFR AND VFR CONDITIONS EXPECTED ACROSS SOUTHERN NEW
ENGLAND. MVFR...WITH SOME BORDERLINE IFR CONDITIONS...WERE PREVALENT
ACROSS THE EASTERN HALF OF SOUTHERN NEW ENGLAND EARLY THIS MORNING...
MAINLY EAST OF KAFN-KORE-KBDL. THESE CONDITIONS WILL PERSIST FOR THE
NEXT SEVERAL HOURS WITH A LIGHT ONSHORE FLOW AND ABUNDANT LOW LEVEL
MOISTURE.

CONDITIONS SHOULD IMPROVE TO MVFR AFTER DAYBREAK WITH STRONGER WINDS
HELPING TO MIX THE LOW LEVELS. EXPECTING NUMEROUS SHOWERS AND
ISOLATED THUNDERSTORMS TODAY INTO THIS EVENING. THE STRONGEST
CONVECTION WILL BE THIS MORNING ACROSS NORTHERN CT AND WESTERN AND
CENTRAL MA. THIS AXIS SHIFTS JUST OFFSHORE LATE TODAY INTO TONIGHT.

MOSTLY VFR CONDITIONS DEVELOPING TONIGHT...WITH MVFR IN SHOWERS.

VFR CONDITIONS THURSDAY.

OUTLOOK...THURSDAY NIGHT THROUGH SUNDAY...

MAINLY VFR. MAY SEE PATCHY LATE NIGHT AND EARLY MORNING FOG IN THE
INTERIOR VALLEYS EACH DAY WITH ISOLD MVFR-IFR VSBYS.  MAY SEE
PERIODS OF CLOUDS AT 4-6KFT THROUGH SUNDAY.

&&

.MARINE...
WINDS WILL REMAIN BELOW SMALL CRAFT ADVISORY THRESHOLDS THROUGH
TONIGHT...BUT THE COMBINATION OF EASTERLY SWELL AND DEVELOPING
SOUTHERLY WIND WAVE WILL CONTINUE TO BRING SEAS UP TO 5 FT ACROSS THE
OUTER WATERS. HAVE EXTENDED THE SMALL CRAFT ADVISORY FOR SEAS THROUGH
TONIGHT. WEST WINDS SHOULD INCREASE THURSDAY ACROSS THE WATERS...AND
MAY NEED TO EXTEND THE SMALL CRAFT ADVISORY EVEN LONGER FOR SOME OF
THE WATERS. WILL HOLD OFF FOR NOW UNTIL CONFIDENCE IMPROVES A BIT
MORE AS WIND SPEEDS ARE MARGINAL.

OUTLOOK...THURSDAY NIGHT THROUGH SUNDAY...

THURSDAY NIGHT-FRIDAY...AFTER THE FRONT PASSES OFFSHORE...WILL SEE
SOME GUSTS UP TO 25 KT MAINLY OVER THE OPEN WATERS ON FRIDAY. SEAS
WILL BUILD TO 3-6 FT.

SATURDAY-SUNDAY...W-NW WINDS MAY SEE GUSTS UP TO 20 KT. SEAS WILL BE
SLOW TO SUBSIDE...REMAINING AT OR ABOVE 5 FT ON THE EASTERN OUTER
