AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE TAUNTON MA
219 PM EDT MON AUG 4 2014

.SYNOPSIS...
NEAR OR JUST BELOW NORMAL TEMPERATURES ARE EXPECTED THIS WEEK.
WHILE MOST OF THE TIME WILL BE DRY...A FEW ROUNDS OF SCATTERED
SHOWERS/THUNDERSTORMS ARE EXPECTED WITH ACTIVITY MOST WIDESPREAD
ON WEDNESDAY. MEANWHILE...HURRICANE BERTHA IS EXPECTED TO PASS
ABOUT 300 MILES SOUTHEAST OF NANTUCKET TUESDAY NIGHT. THIS WILL
HAVE LITTLE IMPACT ON OUR REGION OTHER THAN POTENTIAL FOR HIGH
SURF AND DANGEROUS RIP CURRENTS.

&&

.NEAR TERM /UNTIL 6 PM THIS EVENING/...
***SCT SHOWERS/ISOLD THUNDERSTORMS MAY RESULT IN VERY LOCALIZED
 HEAVY RAINFALL INTO THIS EVENING***

145 PM UPDATE...
SCT SHOWERS HAVE DEVELOPED ACROSS PORTIONS OF THE CT VALLEY ALONG
A WEAK TROUGH NOTED ON MSAS MAP OVER THE LAST FEW HOURS. THESE
HAVE SLOWLY MOVED INTO SW NH AND N CENTRAL MA. LIGHT WINDS AT THE
SURFACE AND ALOFT HAVE CAUSED THESE SHOWERS TO MOVE VERY SLOWLY E
OR EVEN RAIN THEMSELVES OUT...ONLY TO HAVE A FEW MORE DEVELOP NEAR
THE WEAK CONVERGENCE ZONE. HAVE ALSO NOTED A FEW SHOWERS THAT
DEVELOPED ACROSS S CENTRAL NH IN THE LAST COUPLE OF HOURS. A FEW
MORE SHOWERS HAVE DEVELOPED ACROSS S CT WHICH MAY SLOWLY MOVE INTO
SW RI THROUGH THE AFTERNOON.

SEA BREEZES HAVE DEVELOPED ALONG THE E COAST...WHICH MAY ALSO
CAUSE A FEW SHOWERS TO DEVELOP JUST INLAND. WILL MONITOR THESE
CLOSELY. HAVE NOT NOTED ANY THUNDER/LTNG YET...BUT CAN NOT RULE
OUT ISOLD ACTIVITY THROUGH THE REMAINDER OF THE DAY.

HAVE UPDATED GRIDS TO BRING CONDITIONS CURRENT.

PREVIOUS DISCUSSION...
MARGINAL INSTABILITY OF 500 TO 1000 J/KG OF CAPE IN PLACE AND WILL
CONTINUE TO COMBINE WITH A RELATIVELY UNCAPPED ATMOSPHERE.
SCATTERED SHOWERS WILL CONTINUE TO DEVELOP THROUGH THE REMAINDER
OF THE DAY.

WEAK WIND FIELDS FROM 700 MB TO THE SURFACE WILL CAUSE ANY SHOWERS
AND STORMS THAT DO DEVELOP TO BE VERY SLOW MOVING. THIS WILL
BRING THE POTENTIAL FOR LOCALLY HEAVY RAINFALL AND PERHAPS A LOW
PROBABILITY FOR AN ISOLATED FLASH FLOOD EVENT. ONE OF THE LIMITING
FACTORS WILL BE SOME DRY MID LEVEL AIR/SUBSIDENCE THAT WILL WORK
INTO THE REGION BEHIND A SHORTWAVE THIS MORNING. THIS MAY TAME
SOME OF THE ACTIVITY...BUT THERE IS AT LEAST THE POTENTIAL FOR
SOME VERY LOCALIZED FLOODING.

&&

.SHORT TERM /6 PM THIS EVENING THROUGH 6 PM TUESDAY/...
TONIGHT...

ANY SCATTERED SHOWERS/ISOLATED THUNDERSTORMS WILL COME TO AN END
THIS EVENING.  OTHERWISE...DRY WEATHER EXPECTED OVERNIGHT AS LOW
TEMPS BOTTOM OUT IN THE UPPER 50S TO THE MIDDLE 60S.  AREAS OF FOG
WILL ONCE AGAIN DEVELOP LATE...SOME OF WHICH COULD BE LOCALLY DENSE
IN THE TYPICALLY PRONE LOCATIONS.

TUESDAY...

A WARM AND SOMEWHAT HUMID DAY IS ON TAP FOR THE REGION UNDER A
MIXTURE OF CLOUDS AND SUN.  HIGHS SHOULD TOP OUT WELL INTO THE 80S
IN MOST LOCATIONS.  MARGINAL INSTABILITY WILL ONCE AGAIN DEVELOP
WITH 500 TO 1000 J/KG OF CAPE.  HOWEVER...THERE WILL BE A LOT OF DRY
AIR IN THE MID LEVELS OF THE ATMOSPHERE THAT WILL HURT UPDRAFT
FORMATION.  ALSO...SYNOPTIC SCALE FORCING IS QUITE LIMITED.
THEREFORE...ANY ACTIVITY THAT DEVELOPS TUESDAY AFTERNOON WILL BE
LESS THAN TODAY AND RATHER ISOLATED...WITH MOST AREAS REMAINING
DRY. DECIDED TO COVER THAT WITH SLIGHT CHANCE POPS FOR NOW.

&&

.LONG TERM /TUESDAY NIGHT THROUGH SUNDAY/...
* SHOWERS AND THUNDERSTORMS POSSIBLE THROUGH THE MUCH OF THE WORK
  WEEK
* HIGH PRESSURE BRINGS DRIER WEATHER TOWARDS NEXT WEEKEND

04/00Z GFS AND 03/12Z ECMWF ARE IN GOOD AGREEMENT THROUGH THE LONG
TERM.  FORECAST IS FOR A FAIRLY ACTIVE WEATHER PATTERN WITH A
PERSISTENT MID LEVEL TROUGH OVER THE NORTHEAST THROUGH THE END OF
THE WORK WEEK.  A COLD FRONT WILL MOVE THROUGH SOUTHERN NEW ENGLAND
WEDNESDAY WHILE TROPICAL STORM BERTHA PASSES WELL SOUTHEAST OF
SOUTHERN NEW ENGLAND. THE MID LEVEL TROUGH MOVES OVER THE REGION
WEDNESDAY AND THURSDAY... MOVING OFFSHORE FRIDAY.  HIGH PRESSURE
BUILDS INTO SOUTHERN NEW ENGLAND FOR THE WEEKEND.

WEDNESDAY...WHILE STILL A LOW CONFIDENCE FORECAST... THIS WILL BE
THE BEST DAY FOR STRONG TO SEVERE STORMS WITH THE COLD FRONT MOVING
ACROSS SOUTHERN NEW ENGLAND AND A MID LEVEL COLD POOL MOVING OVER
THE REGION.  THIS WILL PROVIDE NOT JUST A BETTER CHANCE FOR LARGE
HAIL BUT ALSO STEEPEN MID LEVEL LAPSE RATES...CREATING BETTER
INSTABILITY.  IN ADDITION... MODELS INDICATE 30-40 KTS OF 0-6 KM
SHEAR AND CAPE VALUES GREATER THAN 1500 J/KG.  MAIN CONCERN FOR
STORMS WILL BE HAIL...HOWEVER THERE IS POTENTIAL FOR SOME HEAVY RAIN
WITH TROPICAL STORM BERTHA PASSING TO THE SOUTHEAST.  WHILE BERTHA
IS EXPECTED TO PASS WELL TO THE SOUTHEAST OF SOUTHERN NEW
ENGLAND...IT WOULD NOT BE OUT OF THE QUESTION TO SEE SOME TROPICAL
MOISTURE MOVE INTO THE REGION.  MODEL PRECIPITABLE WATERS INDICATE
THAT THIS IS NOT GOING TO HAPPEN BUT IT BEARS WATCHING.

THURSDAY AND FRIDAY...THE CENTER OF THE COLD POOL MOVES OVER
SOUTHERN NEW ENGLAND THURSDAY AND THEN SLOWLY SHIFTS OFFSHORE
FRIDAY.  WHILE SHOWERS AND THUNDERSTORMS ARE POSSIBLE BOTH
DAYS...THE BETTER CHANCE IS THURSDAY WITH BETTER INSTABILITY
AVAILABLE.  HIGH PRESSURE STARTS TO BUILD OVER THE REGION ON FRIDAY
AS THE MID LEVEL TROUGH MOVES OFFSHORE.

SATURDAY AND SUNDAY...HIGH PRESSURE BUILDS INTO SOUTHERN NEW ENGLAND
BRINGING DRIER WEATHER AND MORE SEASONABLE TEMPERATURES.

&&

.AVIATION /18Z MONDAY THROUGH SATURDAY/...
FORECASTER CONFIDENCE LEVELS...

LOW...LESS THAN 30 PERCENT.
MODERATE...30 TO 60 PERCENT.
HIGH...GREATER THAN 60 PERCENT.

SHORT TERM...THIS AFTERNOON THROUGH TUESDAY NIGHT...

THIS AFTERNOON...MODERATE TO HIGH CONFIDENCE.
EXPECT MAINLY VFR CONDITIONS. SCATTERED SHOWERS WILL CAUSE BRIEF
MVFR-IFR CIGS/VSBYS MAINLY ACROSS CENTRAL AND WESTERN AREAS. SEA
BREEZES ALONG THE E COAST WILL SHIFT TO LIGHT S BY EVENING.

TONIGHT...MODERATE CONFIDENCE.
VFR CONDITIONS DURING THE EVENING WILL LOWER TO MVFR-IFR LEVELS
IN AREAS OF LOW CLOUDS/FOG AFTER 03Z-05Z EXCEPT EARLIER ACROSS
CAPE COD AND THE ISLANDS. LOCAL LIFR AFTER 06Z ACROSS OUTER CAPE
COD AND NANTUCKET. LOWER CONFIDENCE ON COVERAGE OF LOWER
CONDITIONS.

TUESDAY...MODERATE TO HIGH CONFIDENCE.
AREAS OF LOW CLOUDS/FOG PATCHES WILL BURN OFF BY LATE MORNING.
OTHERWISE...MAINLY VFR CONDITIONS. AN ISOLATED SHOWER/THUNDERSTORM
IS POSSIBLE DURING THE AFTERNOON ACROSS THE INTERIOR...THOUGH MOST
OF THE REGION WILL REMAIN DRY.

TUESDAY NIGHT...MODERATE CONFIDENCE.
ANY ISOLD SHOWERS/THUNDERSTORMS WILL DISSIPATE BY 03Z...OTHERWISE
VFR. AFTER 04Z-05Z...AREAS OF LOW CLOUDS/FOG DEVELOP AGAIN WITH
MVFR-IFR CONDITIONS...EXCEPT EARLY ACROSS CAPE COD AND THE
ISLANDS.

KBOS TERMINAL...MODERATE CONFIDENCE. LIGHT SEA BREEZE EXPECTED
THROUGH 22Z...THEN DEVELOPING AGAIN BY MIDDAY TUESDAY.

KBDL TERMINAL...HIGH CONFIDENCE.

OUTLOOK...WEDNESDAY THROUGH FRIDAY...

.MARINE...
FORECASTER CONFIDENCE LEVELS...

LOW...LESS THAN 30 PERCENT.
MODERATE...30 TO 60 PERCENT.
HIGH...GREATER THAN 60 PERCENT.

SHORT TERM...THIS AFTERNOON THROUGH TUESDAY AFTERNOON...

HIGH CONFIDENCE.  A WEAK PRESSURE GRADIENT WILL KEEP WINDS/SEAS
BELOW SCA THRESHOLDS THROUGH TUE AFTERNOON.  THE MAIN CONCERN
FOR MARINERS WILL BE AREAS OF FOG...SOME OF WHICH MAY BE LOCALLY
DENSE LATE TONIGHT INTO EARLY TUE MORNING.

OUTLOOK...TUESDAY NIGHT THROUGH FRIDAY...

TUESDAY NIGHT AND WEDNESDAY...MODERATE CONFIDENCE.  SEAS INCREASE AS
SWELL FROM HURRICANE BERTHA REACHES THE COASTAL WATERS. SMALL
CRAFT ADVISORIES WILL LIKELY BE NECESSARY FOR A PORTION OF THIS
TIME. WINDS REMAIN BELOW 20 KTS. SHOWERS AND THUNDERSTORMS ARE
LIKELY AGAIN WEDNESDAY WITH FOG POSSIBLE TUESDAY NIGHT.

THURSDAY AND FRIDAY...MODERATE CONFIDENCE.  SEAS DIMINISH...FALLING
BELOW SMALL CRAFT CRITERIA.  SHOWERS AND THUNDERSTORMS ARE POSSIBLE
THURSDAY.
