AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE TAUNTON MA
357 PM EDT SAT SEP 8 2007

.SYNOPSIS...
SUB TROPICAL STORM GABRIELLE...PLEASE FOLLOW TPC TRACKS AND DISCUSSIONS
REGARDING THE 4 DAY PROJECTED INTENSITY...RECURVATURE TRACK AND SWATH OF
TROPICAL STORM FORCE WINDS. FIRST ADVISORY WAS AT 11 PM THIS PAST FRIDAY
EVENING.

SOME OF OUR PRODUCTS NORMALLY ISSUED AROUND 4PM AND 4AM MAY BE DELAYED
ABOUT AN HOUR BEYOND NORMALLY DELIVERED TIMES THE NEXT SEVERAL DAYS DUE
TO INTERNAL COLLABORATION WITH TROPICAL PREDICTION CENTER WIND GRIDS.

HIGH PRESSURE OFFSHORE WILL PROVIDE NEAR RECORD HEAT TODAY. A COLD
FRONT WILL CROSS A PORTION OF SOUTHERN NEW ENGLAND TONIGHT STALLING
SUNDAY OR POSSIBLY MOVING NORTH LATE SUNDAY AS A WARM FRONT. THERE
MAY BE A LARGE CONTRAST IN TEMPERATURES ACROSS A PORTION OF OUR AREA.

MONDAY INTO TUESDAY WILL INCORPORATE THE TRACK OF GABRIELLE ALONG
WITH A STRONGER COLD FRONTAL PASSAGE. HIGH PRESSURE SHOULD PREVAIL
OVER THE NORTHEAST WEDNESDAY AND THURSDAY. A NEW COLD FRONT WILL
APPROACH FROM THE WEST LATE FRI.

&&

.NEAR TERM /UNTIL 10 PM THIS EVENING/...
SHOWERS/TSTMS ORGANIZING INTO A LINE AHEAD OF COLD FRONT MOVING SWD
FROM FAR NORTHERN NEW ENGLAND.  SCT-BKN LINE OF CONVECTION FROM S NH
THROUGH BERKS TO SE NY AT 3 PM.  19Z MESOANALYSIS SHOWS MAX
INSTABILITY AXIS WITH MLCAPES 2000+ J/KG FROM SE NH THROUGH CENTRAL
MA AND NW CT.  SO WE EXPECT CURRENT AREA OF CONVECTION TO INCREASE
IN INTENSITY AS IT MOVES INTO VERY FAVORABLE ENVIRONMENT.  AREA FROM
NE MA THROUGH NW CT IS OF MOST CONCERN NEXT FEW HOURS.

WARNING THRESHOLDS ARE 50-55 DBZ TO 26K AND 60-65 DBZ TO 15K.

BASED ON KI/TT AXIS...MAIN AREA OF CONVECTION SHOULD REACH LWM-HFD
LINE EARLY THIS EVENING WHILE GRADUALLY WEAKENING WITH LOSS OF
HEATING AND DECREASING INSTABILITY.  NO WEATHER EXPECTED SOUTH AND
EAST OF BOS-PVD CORRIDOR THROUGH EARLY EVENING.

&&

.SHORT TERM /10 PM THIS EVENING THROUGH 6 PM SUNDAY/...
COLD FRONT WILL SLOWLY MOVE SOUTH TO N MA LATE TONIGHT AND HIGHER
RESOLUTION NAM SUGGESTS IT WILL ONLY GET TO MASS PIKE SUN MORNING
BEFORE STALLING AND EVENTUALLY LIFTING BACK NORTH SUN NIGHT.

MODELS SHOW GOOD OVERUNNING NORTH OF BOUNDARY WITH BEST LIFT ACROSS
NORTHERN NEW ENGLAND LATE TONIGHT AND SUN.  BUT IT DOES APPEAR
SOUTHERN EXTENT OF OVERUNNING MOISTURE/LIFT WILL AFFECT FAR N ZONES
LATE TONIGHT AND SUN WHERE IT MAY BE WET.  IT WILL BE DRIER SOUTH OF
THE BOUNDARY ACROSS CT/RI AND SE MA AND EXPECT LITTLE OR NO PRECIP
THROUGH SUN CLOSER TO THE SOUTH COAST.  IN FACT...DRIER AIR FROM THE
OCEAN ADVECTS NORTHWARD ACROSS SOUTH COASTAL AREAS ON SUN WITH 850
TDS DROPPING TO NEAR ZERO AND SO WE EXPECT SOME SUNSHINE WILL
DEVELOP ACROSS PORTIONS OF CT/RI AND SE MA ON SUN.

WE RELIED ON SREF AND GFS ENSEMBLE MEAN POPS AND HAVE INDICATED
LIKELY POPS LATE TONIGHT/SUN NORTH OF ROUTE 2 REGION DECREASING TO
SLIGHT CHANCE NEAR THE SOUTH COAST BUT LITTLE IF ANY PRECIP EXPECTED
IN THE COASTAL PLAIN.  WE ALSO INCLUDED THUNDER ON SUN AWAY FROM S
COAST BASED ON ELEVATED INSTABILITY PARAMETERS.

DIFFICULT TEMP FCST SUNDAY DUE TO STRATUS COOL ELY FLOW SEPARATED
FROM RESIDUAL BL WARMTH S OF THE BOUNDARY. MUCH COOLER DAY ON SUN N
OF THE BOUNDARY ACROSS N MA AND S NH LOCKED IN CLOUDS AND SHOWERS
WITH TEMPS IN THE LOWER 70S AND POSSIBLY FALLING INTO 60S NE MA.
BUT TEMPS SHOULD REACH 80 DEGREES S OF THE PIKE WHERE SOME SUNSHINE
WILL LIKELY DEVELOP...AND GIVEN LEFTOVER WARM 850 MB TEMPS...IT
COULD GET INTO MID 80S IF THERE IS ENOUGH SUNSHINE BUT LOW
CONFIDENCE AT THIS TIME.

&&

.LONG TERM /SUNDAY NIGHT THROUGH SATURDAY/...
AN UPPER LEVEL RIDGE PREVAILS ACROSS THE FORECAST AREA DURING
SUNDAY. A SERIES OF SHORT WAVE DISTURBANCES TRACKING FROM THE OHIO
VALLEY INTO SOUTHERN NEW ENGLAND WILL ALLOW THE UPPER LEVEL RIDGE
TO GRADUALLY FLATTEN ALLOWING FOR A MORE ZONAL PROGRESSIVE FLOW.
IN ADDITION WILL NEED TO PAY ATTENTION TO THE RECENT DEVELOPMENT OF
SUBTROPICAL LOW GABRIELLE WHICH IS GRADUALLY GETTING MORE ORGANIZED
OFF THE SOUTHEAST U.S. COAST. AN UPPER LEVEL TROUGH DEEPENING ACROSS
THE MIDSECTION OF THE COUNTRY LATER THIS WEEK WILL ALLOW THE UPPER
LEVEL RIDGE TO REBUILD ACROSS THE EASTERN SEABOARD.

A WEAK COLD FRONT WILL ADVANCE INTO SOUTHERN NEW ENGLAND ON MONDAY
WHICH IS MORE PROGRESSIVE THAN SOME OF YESTERDAYS 00Z GUIDANCE.
WEAK HIGH PRESSURE WITH ITS SHALLOW MARINE AIRMASS WILL BEGIN LOSE
ITS INFLUENCE ACROSS SOUTHERN NEW ENGLAND. VERTICAL CROSS SECTIONS
INDICATE LOTS OF LOW LEVEL MOISTURE. ALTHOUGH THE WARM FRONT MAY
NEVER LIFT NORTH OF THE ENTIRE REGION...SUNSHINE MAY BURN THROUGH
THE LOW LEVEL INVERSION AWAY FROM THE COAST AND COULD ALLOW
TEMPERATURES TO RISE AROUND 80 DEGREES OR HIGHER. HOWEVER WITH THE
COLD FRONT NEARBY WILL KEEP TEMPERATURES SOMEWHAT CONSERVATIVELY
WARM FOR NOW AND UNDERCUT MOS TEMPS BY JUST A FEW DEGREES. WILL
ALSO CONTINUE WITH CHANCE POPS.

OUR ATTENTION TURNS TO SUBTROPICAL STORM GABRIELLE WHICH IS BECOMING
GRADUALLY BETTER ORGANIZED OFF THE SOUTHEASTERN U.S. COAST. THE LOW
IS PROGGED BY THE TROPICAL PREDICTION CENTER TO MAKE LANDFALL ALONG
THE NORTH CAROLINA COAST SUNDAY MORNING BEFORE MAKING A SHARP TURN TO
THE NORTHEAST...TRACKING ACROSS THE OFFSHORE WATERS TUESDAY MORNING.
OUR WIND GRIDS WERE POPULATED WITH THE LATEST TCM DATA FROM THE
TROPICAL PREDICTION CENTER. THIS SHOULD BRING TROPICAL STORM FORCE
WINDS NEAR OR JUST OUTSIDE THE OUTER COASTAL WATERS TUESDAY. OTHERWISE
CONTINUED WITH CHANCE POPS TUESDAY AT THIS TIME AS A COLD FRONT IS
EXPECTED TO SLOWLY CROSS THE REGION.

DID NOT MAKE ANY CHANGES BEYOND TUESDAY AT THIS TIME EXCEPT
TO MODIFY WIND VELOCITIES TUESDAY INTO WEDNESDAY MAINLY DUE TO
GABRIELLE FOR COLLABORATIVE PURPOSES. OTHER ELEMENTS MAY NEED TO BE
MODIFIED IN FUTURE RUNS FOR CONSISTENCY PURPOSES WEDNESDAY DAY 5
DEPENDING ON THE PROJECTED TRACK OF GABRIELLE. THE LATEST GFS/ECMWF
BUILDS A HIGH PRESSURE AREA INTO THE NORTHEAST. THIS MAKES SOME SENSE
GIVEN A DEVELOPING PROGRESSIVE UPPER LEVEL FLOW. MORE UNSETTLED
WEATHER COULD DEVELOP LATER IN THE WEEK AS THE MIDWESTERN TROUGH
DEEPENS AND A COLD FRONT APPROACHES.

&&

.AVIATION /19Z SATURDAY THROUGH THURSDAY/...
SCATTERED THUNDERSTORMS MAY BRIEFLY LOWER CONDITIONS TO MVFR/IFR
THROUGH EARLY THIS EVENING MAINLY ACROSS INTERIOR TAF
SITES...OTHERWISE VFR. MORE WIDESPREAD MVFR/IFR CONDITIONS LIKELY
LATER TONIGHT WITH AREA OF SHOWERS POSSIBLY DEVELOPING FROM CT
VALLEY NORTHWARD TO SOUTHERN NH AND MERRIMACK VALLEY.

TRICKY FORECAST FOR SUN AS FRONT WILL LIKELY STALL NEAR MASS PIKE
REGION. NORTH OF THE BOUNDARY WIDESPREAD MVFR/IFR LIKELY INCLUDING
KMHT/KBOS WITH LESS PROBABILITY AT KBAF...AND STEADY OVERRUNNING
SHOWERS LIKELY ACROSS N MA AND S NH. SOUTH OF THE BOUNDARY...AREAS
OF MVFR/IFR SHOULD IMPROVE TO VFR BY MIDDAY AS DRIER AIR ADVECTS
NORTHWARD FROM THE OCEAN.

SUNDAY NIGHT THROUGH WEDNESDAY...A COLD FRONT WILL BRING SCATTERED
SHOWERS AND THUNDERSTORMS WITH MARGINAL VFR/IFR CONDITIONS MONDAY AND
TUESDAY. FOG PATCHES AND STRATUS WILL BRING IFR CONDITIONS SUNDAY
NIGHT AND AGAIN MONDAY NIGHT MAINLY ALONG THE COAST AND INTERIOR
VALLEYS. CONDITIONS MAY IMPROVE TO VFR BEHIND THE COLD FRONT IN
NORTHWEST FLOW BY LATE TUESDAY AND WEDNESDAY.

&&

.MARINE...
SHORT TERM...SMALL CRAFT ADVISORY EXTENDED UNTIL 8 PM FOR NEARSHORE
WATERS.  WINDS WILL SUBSIDE OVERNIGHT WITH SW FLOW 10-15 KTS ON SUN
SOUTHERN WATERS...AND LIGHT ELY FLOW ACROSS NE WATERS.  SEAS OVER
OUTER WATERS SHOULD REMAIN BELOW 5 FT.

SUN...SHIFTING WINDS...BRIEF PRD OF 20-25 KT NE WINDS IN THE MORNING.
THEN AS WINS SETTLES...DENSE FOG MAY BECOME A NAVIGATION PROBLEM NR
THE FRONTAL BOUNDARY.

LIGHT ONSHORE FLOW SUNDAY NIGHT WILL DIMINISH...WITH WINDS VEERING
TO THE SOUTH MONDAY AHEAD OF A COLD FRONT. WINDS WILL SHIFT TO
NORTHWEST BEHIND A COLD FRONT TUESDAY NIGHT AND WEDNESDAY. WINDS
MAY INCREASE CLOSE TO TROPICAL STORM FORCE FOR A TIME TUESDAY ACROSS
THE OUTER PORTIONS OF ANZ254-255. ANY INCREASE IN SWELL SHOULD BE
CONFINED TO THOSE LOCATIONS GIVEN THE LOW TRACK ALMOST DUE EAST.

SUB TROPICAL STORM GABRIELLE IS APPROACHING THE SOUTHEAST COAST OF

SOUTHEAST OF NEW ENGLAND THIS COMING MONDAY AND TUESDAY SHOULD
MONITOR FORECASTS EVERY 6 TO 12 HOURS INCLUDING TROPICAL PREDICTION

WINDS. THERE CAN BE LARGE TRACKING ERRORS FOR STORMS 3 TO 4 DAYS IN
