AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE TAUNTON MA
448 AM EDT SAT JUN 2 2007

.SYNOPSIS...
UNSTABLE MUCH ABOVE NORMAL WARMTH PRODUCING MORE SEVERE STORMS THIS WEEKEND
THEN THE REMNANTS OF TS BARRY MONDAY FOLLOWED BY A BRIEF COOL DOWN MIDDLE
OF NEXT WEEK BEFORE MODEL CONFLICT LATE NEXT WEEK...BIG HEAT /EC-UKMET
AND SOME MEMBERS GFS..VS NORMAL TEMPS OF 18Z OP RUN GFS?

&&

.NEAR TERM /UNTIL 11 AM THIS MORNING/...
PER RADAR AND GRADUAL WARM ADVECTION...SHOWERS AND ISOLATED TSTMS MOVING
ACROSS NYS AND SHOULD MAINTAIN ORGANIZATION INTO THE VERY W PART OF MASS
AND SW NH EARLY THIS MORNING. SHOULD NOT HAVE SVR THIS MORNING. DENSE OG
ORE-EEN ETM. CLOUD COVER MAY BE PRETTY THICK THROUGH 9AM THEN SLOWLY THIN
AND ALREADY A PRETTY WARM START ON TEMPS AND WE RAPIDLY MOVE TO SIMILAR
VALUES AS YDYS HIGH TEMPS.

&&

.SHORT TERM /11 AM THIS MORNING THROUGH 6 PM SUNDAY/...
SVR THIS AFTN LIKELY TO BE WORSE THAN THIS PAST FRI EVENING /SEE FRI
LSR/. SPC DAY1 OUTLOOK DISC COVERS. LARGE TT/KI THIS AFTN.

DIRECTIONAL SHEAR IS LARGER TODAY INDICATING BETTER WAA BENEATH WNW
FLOW ALOFT. BLV WE HAVE A BETTER SHOT AT MESOS SAT AFTN WITH BIGGER
CAPE COMPENSATING FOR MODEST SPEED SHEAR.

GFS ENS POPS FOR .05 UTILIZED ALONG WITH MULTIMODEL QPF AGREEMENT FOR
INCREASING POPS BDL-ORH-BOS NORTHWARD. DONT THINK WELL MUCH IF
ANYTHING S OF PVD-PYM UNLESS WE GET IT ARD 8AM. TENDENCY TO DRY NR
THE S COAST THIS AFTN.

SEABREEZES THIS AFTN VCNTY BOS TO CAPE ANN...SOME UNCERTAINTY HOW
PRONOUNCED THESE ARE...POSSIBLY LESS EFFECTIVE THAN YDY.

CONFIDENCE IS HIGH FOR THE SCENARIO ABOVE AND IN THE PRODUCTS.

TONIGHT..THUNDER DIMINISHES LATE THIS EVE BUT POSSIBLY MAINTAINS
ALONG AN AXIS FM BOS-BDL. UNCERTAIN HOW LONG CONVECTION WILL CONTINUE
TONIGHT AND THIS FCST MAY BE OVERDONE ON THAT POSSIBILITY. GFS/UKMET
FAVORED FOR THIS FCST PRD. CONFIDENCE AVG OR BLO AVG ON HOW
CONVECTION LASTING PAST 10 PM. NEVER LIKE SEEING KI AS HIGH AS HAVE
IN THE GFS FOR TONIGHT. MODELS CIORRECTLY PREDICTED BURGEONING KI
PREDAWN TODAY AND YOU SEE WHAT RADAR IS BRINGING US NOW CROSSING THE
BERKS.

SUN...CONVECTION REFIRES NW MASS IN REMAINING UNSTABLE AIR THAT IS SLOWLY
LIFTING N IN RESPONSE TO RDG ALOFT MOVING N AHEAD OF WHAT REMAINS OF TS
BARRY. OTRW...TENDENCY TO DRY OUT MIDDAY AND AFTN BOS-IJD SOUTHWARD
AND IT SHOULD BE A NICE AFTN FM BOS-IJD SEWD TO THE CAPE.

&&

.LONG TERM /SUNDAY NIGHT THROUGH FRIDAY/...
FOR THIS PERIOD...PUTTING ENTIRE FOCUS ON SUN NIGHT AND MON...WHEN
REGION IS IMPACTED BY BARRY OR ITS REMNANTS.

THE UPPER JET STRUCTURE IS NOT ALL THAT IMPRESSIVE ON EITHER THE NAM
OR GFS. HOWEVER...BOTH NAM AND GFS SHOW 50 TO 60 KT LOW LEVEL JET AT
925 MB TO E OF CENTER.  THERE ALSO SEEMS TO BE TREND FOR MODELS TO
CONVERGE ON A TRACK THAT WOULD TAKE THE SURFACE LOW CENTER ACROSS RI
OR SE MA. ISSUES TO LOOK AT INCLUDE WIND GUST POTENTIAL E OF
CENTER...HEAVY RAFL...HIGH SURF AND SVR. MIGHT ALSO HAVE TO BE
CONCERNED WITH TIDAL DEPARTURE OF 1 TO 3 FT UP NARRAGANSETT BAY IF
CENTER IS A BIT FURTHER TO THE W.

ANTICIPATING SQUALLS WITH 40 KT GUSTS TO E OF CENTER AND MAY
EVENTUALLY NEED GALE WARNING FOR MANY OF S COAST WATERS. SE MA AND
PSBLY PORTIONS RI MAY EXPERIENCE WIND GUSTS 40 TO 50 MPH IN SQUALLS.

EXPECT THIS SYSTEM TO DRAW TROPICAL MOISTURE INTO REGION BUT NOTE
THAT QPF FROM BOTH NAM AND GFS NOT ALL THAT IMPRESSIVE...PSBLY
REFLECTIVE OF A FAIRLY WEAK/DISORGANIZED UPPER JET STRUCTURE. STILL
HAVE TO BE WARY OF TROPICAL MOISTURE AND PRECIP WATERS 1.5 TO 1.75
INCHES AND MAY SEE SWATH OF 2 TO 4 INCHES RAFL OCCURRING IN 6 TO 8
HOUR TIME FRAME.

CLIMATOLOGY WOULD SUGGEST SOME WARINESS TOWARD POTENTIAL SVR ON MON
AS WELL.

HIGH SURF POTENTIAL EXISTS TO E OF CENTER ALONG S AND SE FACING
COASTS LATE SUN NIGHT AND MON.

AS FAR AS POPS AND TEMPS...HAVE UPPED POPS TO CATEGORICAL FOR SUN
NIGHT AND THEN TAPER BACK TO LIKELY AND EVENTUALLY CHC ON MON. MOS
GUID LOOKED REASONABLE FOR SUN NIGHT BUT OPTED TO RAISE SEVERAL
DEGREES ON MON. THINK A GOOD CHC THAT WILL SEE SOME BREAKS MON
AFTERNOON TO DRIVE TEMPS HIGHER THAN GUID...ESPECIALLY MAV GUID.

ANOTHER LOW PRESSURE FROM THE GREAT LAKES SHOULD STILL IMPACT
SOUTHERN NEW ENGLAND TUESDAY.  HIGH PRESSURE THEN EXPECTED TO TAKE
OVER LATE WEDNESDAY INTO FRIDAY.

&&

.AVIATION /08Z SATURDAY THROUGH WEDNESDAY/...
BELIEVE ITS INEVITABLE FOR LIFR FOG TO FORM ACK AND HYA SOMETIME TODAY
AS SFC TDS 58 TO 63 ABV SST IN THE 50S. FOR BOW HAVE FCST THE FOG TO
DVLP THIS AFTN OR EVE BUT IT COULD BE SOONER?

OTHERWISE HAZY MVFR VSBY AT TIMES TODAY.

TSTMS THIS AFTERNOON WILL BRIEFLY LOWER CONDITIONS TO MVFR. BASED ON
KI/LI PARAMETERS...BULK OF CONVECTION WILL LIKELY BE IN THE INTERIOR.
BLV TSTMS WILL FORCE REROUTING OF AIR TRAFFIC FM LOGAN/BDL ETC BOUND
FOR ALB AND POINTS WEST. PLAN FOR AIR TRAVEL DELAYS EVEN IF NO THUNDER
AT LOGAN. I THINK THE CHANCE OF NO THUNDER AT LOGAN THIS AFTN IS LESS
THAN 30 PCT. IN OTHER WORDS...I THINK WE HAVE A BIG TSTM AFTN AHEAD
OF US FOR SNE AND LOTS OF LIGHTNING IN NW FLOW SVR WX EVENTS.

PATCHY IFR CONDITIONS TONIGHT IN FOG AROUND CAPE COD AND THE ISLANDS.
STILL AS RISK OF MVFR CONDITIONS IN SHOWERS AND THUNDERSTORMS INTO
SUNDAY.

THE REMNANTS OF TROPICAL STORM BARRY WILL LIKELY PRODUCE WIDESPREAD
MVFR AND PSBLY IFR CIGS/VSBYS SUN NIGHT INTO MON MORNING. IN
ADDITION...LLWS AND STRONG SURFACE WIND GUSTS MAY BE AN ISSUE IN SOME
SE MA AND S COAST RI LOCATIONS. DURING MON...SCT TSTMS MAY ALSO HAVE
AN IMPACT ON AVIATION.

HIGH PRESSURE RETURNS VFR CONDITIONS TO ALL OF SOUTHERN NEW
ENGLAND LATE WEDNESDAY.

&&

.MARINE...
IN THE SHORTER TERM...WAVEWATCH IS STILL TOO HIGH ON THE SEAS AND
CUT BACK SOME MORE TODAY. MARGINAL SCA CONDS IN ONE SRN OUTER WATER
ZONE. SRN SOUNDS SEAS MAY NEED SOME MORE CUTTING OF WH IN LATER FCST
ISSUANCES. FOG COULD BECOME A NAVIGATION PBLM TONIGHT INTO SUN MORNING
BEFORE DRIER AIR FM THE S DURING MIDDAY SUNDAY PROBABLY REDUCES FOG
RISK.

IN THE LONGER TERM...BELIEVE THERE IS A RISK OF HIGH END GALE FORCE
GUSTS TO THE E OF THE LOW CENTER LATE SUN NIGHT AND MON...EVEN A
LITTLE WARY OF POTENTIAL FOR BRIEF 50 KT GUSTS IN A FEW SQUALLS.
HAVE BUMPED SEAS UP GIVEN EXPERIENCE OF SYSTEMS LIKE THIS COMING OUT
OF LOW LATITUDES WITH REASONABLY DEFINED WIND CORE. ANTICIPATE UP TO
15 FT SEAS OUTER S AND SE COAST WATERS...PSBLY 8 TO 10 FT EVEN AT
MOUTH OF NARRAGANSETT AND BUZZARDS BAYS DEPENDING UPON TRACK OF LOW
CENTER. SEAS AS HIGH AS 15 TO 20 FT POSSIBLE S AND E OF ACK FOR A
COUPLE HOURS OR SO ON MON. ROUGH SEAS LIKELY TO MAKE SOME
HARBOR/INLET ENTRANCES VERY HAZARDOUS FOR SMALL CRAFT LATE SUN NIGHT
AND MON.
