AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE TAUNTON MA
352 PM EDT WED JUN 26 2013

.SYNOPSIS...
WARM AND MUGGY CONDITIONS WILL CONTINUE WITH HIT AND MISS SHOWERS
AND THUNDERSTORMS INTO EARLY NEXT WEEK.  THE ACTIVITY LOOKS TO BE
MOST WIDESPREAD THU AFTERNOON INTO FRI WITH THE THREAT FOR HEAVY
RAIN AND FLOODING.

&&

.NEAR TERM /UNTIL 6 AM THURSDAY MORNING/...
A BROAD BAND OF LIGHT-MOD RAIN HAS DEVELOPED AHEAD OF A SHORTWAVE
MOVING THROUGH CENTRAL NEW ENGLAND. WHILE THERE HAS BEEN SOME
ISOLATED CONVECTION EMBEDDED WITHIN THIS BAND...THE CLOUD COVER
HAS KEPT SFC BASED INSTABILITY QUITE LOW SO MUCH OF THE CONVECTION
HAS BEEN ELEVATED AND RATHER WEAK...WITH LITTLE LIGHTNING AND ONLY
ENHANCED RAINFALL. THEREFORE...NOT EXPECTING MUCH MORE IN THE WAY
OF STRONGER STORMS IN THIS REGION TO CONTINUE THROUGH THE EVENING.

FURTHER S...PARTICULARLY CT/RI/SRN MA...THE COMBINATION OF MORE
SUNSHINE...INCREASING SHEAR AHEAD OF A SECONDARY WAVE HAVE LEAD TO
SOME MORE DISCRETE CONVECTION ALREADY THIS AFTERNOON. WITH THE
MAIN WAVE STILL EXPECTED TO SLIDE E OVER THE NEXT FEW HOURS...AND
FURTHER DESTABILIZATION STILL LEFT IN THE LOWEST LEVELS...STILL
EXPECTING A THREAT FOR SOME STRONG-SEVERE THUNDERSTORMS TO DEVELOP
INTO THE EVENING. WILL HIGHLIGHT THIS WITH A SWATH OF LIKELY POPS
THROUGH THE EVENING. ENHANCED WORDING MAINLY REPRESENTS THE HEAVY
RAIN/GUSTY WIND AND HAIL THREAT. MAY NEED TO UPGRADE THIS WORDING
PER LATEST MD FROM SPC LATER ON THIS AFTERNOON.

AS THE SHORTWAVE MOVES OFFSHORE THROUGH 00-06Z AND DIURNAL
HEATING IS LOST...EXPECT USUAL COLUMN STABILIZATION WITH
CONVECTION GRADUALLY GIVING WAY TO SHRA BEFORE COMING TO AN END
ALTOGETHER. IN FACT...GUIDANCE DOES SHOW A BRIEF MID LVL RIDGE
WHICH WILL DEVELOP DURING THE EARLY MORNING HOURS AHEAD OF A WEAK
BACKDOOR COLD FRONT. THIS SHOULD ACTUALLY PROVIDE NOT ONLY SOME
DRY WX...BUT POSSIBLY EVEN BREAKS IN THE SKIES WHICH COULD ENHANCE
A SECONDARY CONVECTIVE THREAT FOR THU.

MIN TEMPS OVERNIGHT DIP INTO THE MID TO UPPER 60S ACROSS THE
REGION. AND WITH SOME AREAS SEEING EVENING RAFL...EXPECT FOG TO
DEVELOP ONCE AGAIN. THERE IS EVEN THE THREAT THAT SOME OF THIS FOG
COULD BE LOCALLY DENSE BUT SCATTERED RATHER THAN WIDESPREAD.
THEREFORE...WILL HAVE TO MONITOR THE THREAT FOR PATCHES OF DENSE
FOG FOR THE EARLY HALF OF THE MORNING COMMUTE.

&&

.SHORT TERM /6 AM THURSDAY MORNING THROUGH THURSDAY NIGHT/...
THURSDAY...
ANOMALOUS PATTERN FOR JUNE AS A SERIES OF VERY STRONG VORT MAXES
FROM WEAKENED CONVECTIVE COMPLEXES NEAR THE GREAT LAKES WILL BE
SLIDING INTO LONGWAVE TROUGH OVER SRN ONTARIO AND QUEBEC. THIS
WILL ALLOW FOR THE GENERATION OF SFC LOW PRES IN THE SRN GREAT
LAKE...A FEATURE GUIDANCE NOW HAS GOOD AGREEMENT ON. AHEAD OF THIS
LOW...WEAK BACKDOOR COLD FRONT WILL SETTLE OVER SRN NEW ENGLAND
THROUGH THE DAY THEN STALL AS ENERGY FROM THE VORT MAX AND THE
LOW PRES SLIDE E THROUGH THE AFTERNOON. COMBINING THIS FEATURE WITH
DEVELOPING LOW LVL JET TO THE S...AND HAVE RIPE CONDITIONS FOR
ANOTHER ROUND OF SHOWERS WITH EMBEDDED THUNDERSTORMS. INSTABILITY
LOOKS TO BE A BIT WEAKER DURING THE DAY THANKS TO A BIT MORE CLOUD
COVER INITIALLY /ALTHOUGH AS MENTIONED EARLIER...MAY ACTUALLY BE
SOME BREAKS OF SUN INITIALLY/...AND COOLER DAYTIME TEMPERATURES. SB
CAPES ARE HIGHER WELL TO THE SW WITH GENERALLY 500-1000 J/KG
EVIDENT OVER SRN NEW ENGLAND. SHEAR ALSO NOT QUITE AS STRONG AS IT
WAS ON WED. THEREFORE...WITH PWAT VALUES APPROACHING 2.0
INCHES...A FAIRLY TALL SKINNY CAPE PROFILE ON SOUNDINGS...AND DEEP
WARM CLOUD DEPTHS...FEEL BIGGEST THREAT WILL BE HEAVY DOWNPOURS
WITH TRAINING POTENTIAL. CAN/T RULE OUT THAT A WET MICROBURST OR
SMALL HAIL MAY DEVELOP WITH NEAR 1000 J/KG OF CAPE...SO WILL
CONTINUE TO INCLUDE ENHANCED WORDING WITH THIS UPDATE. GIVEN THE
THREAT FOR HEAVY RAIN HOWEVER...AND LOOKING AT STRONGER SYNOPTIC
SCALE FORCING FOR HEAVY RAIN THU NIGHT...WILL BE ISSUING A FLASH
FLOOD WATCH WITH THIS UPDATE.

THU NIGHT...
STRENGTHENING SFC LOW PRES IS EXPECTED TO RIDE W TO E ALONG
STALLED FRONTAL BOUNDARY STRETCHED FROM NY INTO SRN NEW ENGLAND.
AS IT STRENGTHENS...EXPECT THE FORMATION OF A NEAR 40 KT SLY LLJ
WHICH WILL ACT TO ENHANCE RAINFALL ALONG THIS BOUNDARY. WITH SOME
CONVECTIVE ACTIVITY POSSIBLE DURING THE AFTERNOON/EVENING
HOURS...WHICH MAY BECOME ELEVATED THANKS TO MID LVL
WARMING/MOISTENING WITH THE LLJ...THERE CONTINUES THE THREAT FOR
HEAVY RAINFALL WITH SOME LOCALIZED FLOODING POSSIBLE.
THEREFORE...WILL CONTINUE WITH THE THREAT FOR SOME THUNDER WITH
HEAVY RAINFALL AND CARRY FLASH FLOOD WATCH INTO THE OVERNIGHT
HOURS. AT THIS TIME...WILL ESPECIALLY NEED TO WATCH BERKSHIRES AND
WORCESTER HILLS WHERE SOME UPSLOPE ENHANCEMENT IS POSSIBLE.
ALSO...EXACT PLACEMENT OF THE STALLED BOUNDARY COULD DICTATE WHERE
HEAVIEST RAINFALL AXIS LIES FROM W TO E ACROSS THE AREA. GIVEN
PWAT VALUES ARE EXPECTED TO STAY NEAR 2.0 INCHES...ANY CONVECTIVE
ELEMENTS WILL NEED TO BE WATCHED AS WELL.

&&

.LONG TERM /FRIDAY THROUGH TUESDAY/...
HEADLINES...

* NUMEROUS SHOWERS AND THUNDERSTORMS INTO FRIDAY MAY LEAD TO FLOODING
* HIT AND MISS SHOWERS/THUNDERSTORMS THIS WEEKEND AND BEYOND
* WARM AND HUMID THROUGH THE PERIOD

DETAILS...

FRIDAY AND FRIDAY NIGHT...

NUMEROUS SHOWERS AND THUNDERSTORMS WILL PROBABLY BE ON GOING FRIDAY
MORNING AS A SHORTWAVE MOVES THROUGH THE REGION.  THE MAIN THREATS
WILL BE FOR HEAVY RAIN AND FLOODING GIVEN THE HIGH PWAT VALUES IN
PLACE.  WHILE THE ACTIVITY MAY BE MOST NUMEROUS THROUGH THE FIRST
HALF OF FRIDAY...ADDITIONAL ACTIVITY MAY DEVELOP LATER IN THE
AFTERNOON AND EVENING.

SATURDAY THROUGH WEDNESDAY...

UPPER LEVEL TROUGH WILL REMAIN ANCHORED TO OUR WEST THROUGH THE
PERIOD.  AT THE SAME TIME...A BERMUDA HIGH PRESSURE SYSTEM WILL HOLD
IN PLACE. THESE TWO FEATURES WILL KEEP SOUTHERN NEW ENGLAND IN A
WARM AND HUMID WEATHER REGIME.  IN ADDITION...SUBTLE SHORTWAVES WILL
PROVIDE DAILY OCCURRENCES OF HIT AND MISS SHOWERS AND THUNDERSTORMS.
THE BULK OF THE SHOWERS/THUNDERSTORMS WILL OCCUR DURING THE
AFTERNOON AND EVENING. THEY WILL BE MORE WIDESPREAD ON SOME DAYS
THAN OTHERS...BUT THAT IS JUST TOO TOUGH TO PINPOINT THIS FAR IN
ADVANCE.

THE MAIN CONCERNS WITH THE SHOWERS AND THUNDERSTORMS WILL BE FOR
HEAVY RAINFALL GIVEN PWAT VALUES REMAINING BETWEEN 1.5 AND 2 INCHES.
THIS WILL RESULT IN THE THREAT FOR LOCALIZED FLOODING AND PERHAPS A
FEW INSTANCES OF FLASH FLOODING.

AS FOR THE SEVERE WEATHER POTENTIAL...APPEARS THERE WILL BE ENOUGH 0
TO 6 KM SHEAR AND INSTABILITY FOR THE THREAT OF SOME STRONG TO
SEVERE THUNDERSTORMS AT TIMES.  TIMING WHICH DAYS END UP MORE
FAVORABLE AT THIS POINT REMAINS UNCERTAIN.  IT WILL DEPEND UPON
EXACT TIMING OF SHORTWAVES AND INSULATION THAT OCCURS EACH DAY.  THE
ONE LIMITING FACTOR WILL BE POOR MID LEVEL LAPSE RATES GIVEN
SOUTHWEST FLOW ALOFT.  NOW THAT CERTAINLY DOES NOT MEAN THERE WON/T
BE SEVERE WEATHER...BUT A HIGH END WIDESPREAD SEVERE WEATHER
OUTBREAK APPEARS UNLIKELY.

&&

.AVIATION /19Z WEDNESDAY THROUGH MONDAY/...
FORECASTER CONFIDENCE LEVELS...

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

THIS AFTERNOON AND TONIGHT...MODERATE CONFIDENCE.
STILL EXPECTING SOME SHOWERS AND THUNDERSTORMS THROUGH THE EVENING
HOURS WITH A BETTER FOCUS BEING CT/RI AND SRN MA. VFR IS EXPECTED
OUTSIDE OF THESE SHOWERS/STORMS WITH LOCALIZED MVFR CONDITIONS
WITHIN THEM. OVERNIGHT...STORMS DIMINISH...BUT SOME FOG MAY
DEVELOP AT TYPICALLY PRONE AIRPORTS...THE SOUTH COAST...AND THOSE
THAT SAW RAINFALL TODAY. MVFR/IFR EXPECTED IN THIS FOG.

THU INTO THU NIGHT...MODERATE CONFIDENCE.
ANOTHER ROUND OF SHOWERS AND THUNDERSTORMS POSSIBLE WITH SOME
HEAVY RAIN AS WELL. VFR BEGINS THE DAY OUTSIDE OF EARLY MORNING
FOG. BUT LOCALIZED HEAVY RAIN COULD LEAD TO MVFR/IFR CONDITIONS
AGAIN. MORE WIDESPREAD RAIN IS EXPECTED OVERNIGHT THU NIGHT...WITH
MORE WIDESPREAD MVFR/IFR.

KBOS TERMINAL...MODERATE TO HIGH CONFIDENCE IN TAF. MAN REASON FOR
LOWER CONFIDENCE IS ANY SHOWERS/T-STORMS LATE TODAY AND LATE NIGHT
FOG DEVELOPMENT.

KBDL TERMINAL...MODERATE TO HIGH CONFIDENCE IN TAF BUT UNCERTAINTY
OF TIMING OF ADDITIONAL SHOWERS/THUNDERSTORMS THROUGH THE
AFTERNOON AND EVENING.

OUTLOOK...FRIDAY THROUGH MONDAY...

FRIDAY...MODERATE TO HIGH CONFIDENCE.  MVFR-IFR CONDITIONS ARE
EXPECTED FOR THE FIRST PART OF THE DAY IN NUMEROUS SHOWERS AND
THUNDERSTORMS.  SOME IMPROVEMENT MAY OCCUR DURING THE AFTERNOON AND
EVENING.

SATURDAY THROUGH MONDAY...MODERATE CONFIDENCE.  VFR CONDITIONS
LIKELY DOMINATE...BUT BOUTS OF SCATTERED SHOWERS/THUNDERSTORMS WILL
RESULT IN LOWER CONDITIONS AT TIMES.  PATCHY FOG/LOW CLOUDS AT TIMES
ALSO ARE POSSIBLE.

&&

.MARINE...
FORECASTER CONFIDENCE LEVELS...

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

SHORT-TERM THROUGH WEDNESDAY NIGHT...HIGH CONFIDENCE.

TONIGHT INTO EARLY THU... QUIET BOATING WEATHER IS EXPECTED
OUTSIDE OF ANY THUNDERSTORMS LATE THIS AFTERNOON AND EARLY
OVERNIGHT. LOCALIZED LIGHTNING...HEAVY RAIN AND GUSTY WINDS
POSSIBLE IN ANY STORMS. SOME FOG AND STRATUS POSSIBLE OVER S
WATERS TONIGHT.

LATE DAY THU INTO THU NIGHT...
MORE WIDESPREAD SHOWERS AND HEAVY RAINFALL...COMBINED WITH
SOUTHERLY FLOW REACHING 20-25 KT BY LATE DAY WILL LEAD TO LIKELY
HOOD THAT SMALL CRAFT ADVISORIES WILL BE NEEDED. ESPECIALLY AS
SEAS APPROACH 5-6 FT OVER THE SRN OCEAN WATERS BY TOMORROW NIGHT.

OUTLOOK...FRIDAY NIGHT THROUGH MONDAY...

BERMUDA HIGH WILL RESULT IN PERSISTENT SOUTHWEST WINDS ACROSS THE
WATERS THROUGH THE PERIOD.  SOUTHWEST WINDS WILL GUST TO BETWEEN 20
AND 25 KNOTS AT TIMES.  THE WINDS MAY EVEN GUST A BIT STRONGER ALONG
THE NEAR SHORE WATERS DURING THE AFTERNOON HOURS WHERE THERE WILL BE
BETTER MIXING.  IN ADDITION...PERSISTENT LONG SOUTHWEST FETCH WILL
RESULT IN SEAS AT OR ABOVE SCA LEVELS FOR THE SOUTHERN WATERS AND
OUR OUTER-ATLANTIC WATERS MOST IF NOT THE ENTIRE PERIOD. IN
ADDITION...SPORADIC STRONG THUNDERSTORMS AND PATCHY DENSE FOG WILL
BE A HAZARD TO MARINERS.

&&

.HYDROLOGY...
SOME CONVECTION IS POSSIBLE DURING THE LATE AFTERNOON AND EVENING
TODAY...BUT THESE SHOULD GRADUALLY DIMINISH DURING THE OVERNIGHT
HOURS. HOWEVER...ON TUESDAY...A BACKDOOR COLD FRONT WILL LIKELY
STALL IN THE VICINITY AS STRONG LOW PRES APPROACHES FROM THE WEST.
WITH THIS FRONTAL BOUNDARY IN PLACE...AND DECENT MOIST SOUTHERLY
FLOW EXPECTED TO DEVELOP LATE TOMORROW AFTERNOON...THERE IS THE
THREAT FOR HEAVY RAINFALL WITH SLOW TRAINING CONVECTION BEGINNING
IN THE AFTERNOON AND CONTINUING INTO THE OVERNIGHT EVEN AS
RAINFALL BECOMES MORE WIDESPREAD THANKS TO BETTER LARGE SCALE
FORCING. PRECIPITABLE WATER VALUES ARE EXPECTED TO APPROACH 2.0
INCHES. THEREFORE...THERE IS THE THREAT FOR SOME LOCALIZED
FLOODING/FLASH FLOODING ACROSS THE REGION PARTICULARLY LATE DAY
TOMORROW INTO EARLY FRIDAY. WILL NEED TO ESPECIALLY WATCH REGIONS
OF HIGHER TERRAIN WHERE UPSLOPE COULD ENHANCE THE RAINFALL AS WELL
AS URBANIZED AREAS...WHERE CONVECTIVE HEAVY RAIN MAY LEAD TO URBAN
FLOODING. GIVEN ALL OF THIS...WILL BE ISSUING A FLASH FLOOD WATCH
FOR ALL AREAS SAVE FOR THE CAPE...ISLANDS AND SRN NEW HAMPSHIRE
WITH THIS UPDATE. HOWEVER...THERE IS THE POSSIBILITY THAT THIS
MAY NEED TO BE EXPANDED AS MORE DATA BECOMES AVAILABLE AND WE ARE
ABLE TO GET A HANDLE ON CONVECTION LATE TODAY.
