Damaging Winds and Lightning Strikes in Massachusetts, July 23, 2011

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE TAUNTON MA
938 AM EDT SAT JUL 23 2011

.SYNOPSIS...
ONE MORE HOT DAY IS IN STORE FOR TODAY BEFORE A COLD FRONT BRINGS A
RETURN TO MORE SEASONABLE TO EVEN BELOW TEMPERATURES SUNDAY AND INTO
THE MIDDLE OF NEXT WEEK. ALTHOUGH MOST OF THE TIME WILL BE DRY...A
ROUND OF SHOWERS AND ISOLATED THUNDERSTORMS ARE LIKELY LATE MON AND
MON NIGHT.  SUMMERLIKE WARMTH AND HUMIDITY LOOKS TO RETURN LATE NEXT
WEEK...BUT NOT AS EXTREME AS WHAT WE ARE CURRENTLY EXPERIENCING.

&&

.NEAR TERM /UNTIL 6 PM THIS EVENING/...
930 AM UPDATE...
JUST A QUICK UPDATE REGARDING THE ONGOING CONVECTION. WE ARE
SEEING SOME IMPRESSIVE CORE HEIGHTS BUT THE STORMS SEEM TO PULSE
UP AND DOWN. WE HAVE COME CLOSE TO ISSUING A COUPLE OF WARNINGS
BUT THE HIGH CORES HAVE NOT SUSTAINED THEMSELVES AND CROSS
SECTIONS INDICATE A RATHER DISCONTINUOUS LOOKS FROM LOW TO HIGH
LEVELS. NONETHELESS...IT IS POSSIBLE THAT WE MAY NEED TO PULL THE
TRIGGER ON SHORT NOTICE FOR A SVR OR SPECIAL MARINE WARNING. FOR
NOW...WE ARE COVERING THE ACTIVITY IN STATEMENTS. WE THINK THE
ACTIVITY WILL LIKELY MOVE OFFSHORE 15 TO 16Z AND THE SHORT WAVE
TROF MOVES ON THROUGH...BUT A LITTLE CONCERN THAT THESE STORMS
COULD STRENGTHEN SOME IF INTERSECT WITH THE DEWPOINT BOUNDARY
LYING ACROSS OUR SOUTHERN ZONES.

LEAVING THE HEAT ADVISORY UP FOR NOW...ALTHOUGH THE CLOUDS AND
SHOWERS CERTAINLY DELAYING THE TEMP RISE IN EASTERN MA. STILL
THINK THERE MAY BE A FAIRLY RAPID REBOUND LATER...AND THE RAIN
WILL LIKELY INCREASE THE LOW LEVEL HUMIDITY SOME.

630 AM UPDATE...
NUMEROUS SHOWERS AND A FEW EMBEDDED THUNDERSTORMS WERE WORKING
ACROSS NORTHERN MA AND SOUTHERN  NH EARLY THIS MORNING.  HAVE
INCREASED POPS TO LIKELY AND CATEGORICAL FOR THIS ACTIVITY. THIS
PRECIPITATION IS A RESULT OF A SHORTWAVE COMBINING WITH SOME ELEVATED
INSTABILITY. THE ACTIVITY SHOULD COME TO AN END BY LATE MORNING
AS THE SHORTWAVE EXITS THE REGION.

HIGHS TODAY ARE EXPECTED TO TOP OUT WELL UP INTO 90S IF NOT 100
IN A FEW LOCATIONS. GFS 850 MB TEMPERATURES 20-22C ARE MORE
SUPPORTIVE OF THIS WITH W FLOW...WHILE NAM KEEPS IT SLIGHTLY
COOLER. ONE THING WE ARE CONCERNED WITH IS PRESENCE OF THICKER MID
AND HIGH CLOUDS THAT ARE AFFECTING THE REGION WITH THE EARLY MORNING
CONVECTION. RIGHT NOW IT LOOKS LIKE MOST OF THESE WILL THIN OUT BY
AFTERNOON...BUT IF NOT HIGHS WILL BE SEVERAL DEGREES COOLER THAN OUR
CURRENT FORECAST.

MEANWHILE...LOWER DEWPOINTS CONTINUE TO PUSH BEYOND S COAST EARLY
THIS MORNING. 70+ DEWPOINTS WILL REMAIN JUST S OF NEW ENGLAND
TODAY BUT WILL TRY TO RETURN TO S COAST...CAPE COD AND ISLANDS
LATER THIS AFTERNOON.

THIS WILL RESULT IN HEAT INDICES NEAR 100 ACROSS N CT...N RI AND
MUCH OF MA. CONFIDENCE IS HIGH ENOUGH TO ISSUE A HEAT ADVISORY FOR
THESE LOCATIONS TODAY.

APPROACHING COLD FRONT MAY BE ABLE TO TRIGGER ISOLATED SHOWERS OR
THUNDERSTORMS LATER TODAY...PRIMARILY ACROSS CT AND PERHAPS INTO
RI AND SE MA WHERE BEST INSTABILITY AND LOW LEVEL CONVERGENCE IS
PROGGED.

RIP CURRENT FORECAST...LOW RISK AT BEACHES TODAY. LOOKS MARGINAL
FOR A MODERATE RISK ON S FACING BEACHES OF MARTHAS VINEYARD AND
NANTUCKET DUE TO 4 FT S SWELLS OFFSHORE. LATE MORNING UPDATE MAY
NEED TO UPGRADE RISK FOR THOSE LOCATIONS.

&&

.SHORT TERM /6 PM THIS EVENING THROUGH 6 PM SUNDAY/...
COLD FRONT WILL CROSS REGION TONIGHT...FOLLOWED BY DRIER NW FLOW.
ISOLATED SHOWERS/STORMS POSSIBLE EARLY OTHERWISE DRY WEATHER
EXPECTED.

FRONT REMAINS S OF NEW ENGLAND SUN WITH SOMEWHAT COOLER AND DRIER
AIR OVER REGION. WEAK GRADIENT WILL SUPPORT AFTERNOON SEA BREEZES.
HOWEVER WITH FRONT NOT TOO FAR AWAY WE MAY SEE ISOLATED
SHOWERS/STORMS NEAR LOWER CT VALLEY AS MODELS SHOW MCS DROPPING SE
FROM GREAT LAKES. GIVEN UNCERTAINTY KEPT FORECAST DRY FOR NOW.

TEMPERATURES ARE A BLEND OF GFS/NAM MOS.

&&

.LONG TERM /SUNDAY NIGHT THROUGH FRIDAY/...
HIGHLIGHTS...
 *BELOW NORMAL TEMPERATURES WITH COMFORTABLE HUMIDITY LEVELS MON AND
TUE  *A ROUND OF RAIN SHOWERS LIKELY MAINLY LATE MON AND ESPECIALLY
MON NIGHT  *SUMMERLIKE WARMTH AND HUMIDITY RETURNS LATE NEXT WEEK
BUT NOT AS EXTREME   AS THE PAST FEW DAYS

DETAILS...

SUNDAY NIGHT...
A RATHER COMFORTABLE NIGHT IS ON TAP FOR THE REGION COMPARED TO THE
VERY WARM NIGHT/S WE HAVE EXPERIENCED THE LAST FEW DAYS.  WEAK HIGH
PRESSURE OVERHEAD SHOULD RESULT IN PARTLY CLOUDY SKIES AND LIGHT
WINDS.  THE MUCH DRIER AIRMASS IN PLACE WILL ALLOW OVERNIGHT LOWS TO
FALL BACK INTO THE UPPER 50S AND LOWER 60S.

MONDAY...
CLOUDS WILL BE ON THE INCREASE  DURING THE MORNING FROM WEST TO EAST
AS A SHORTWAVE APPROACHES.  STILL SOME TIMING ISSUES AMONGST THE
MODELS...BUT WILL INTRODUCE CHANCE POPS IN THE AFTERNOON WITH THE
BEST CHANCE OF ANY PRECIPITATION BEFORE DARK IN THE INTERIOR.
SURFACE INSTABILITY DOES NOT LOOK THAT IMPRESSIVE IN OUR
REGION...WITH MOST OF IT TO OUT WEST IN NEW YORK STATE.  THERE IS A
BIT OF ELEVATED INSTABILITY...SO WHILE WIDESPREAD THUNDER IS NOT
EXPECTED WILL MENTION THE POTENTIAL FOR ISOLATED THUNDER.  AS FOR
TEMPERATURES...SOUTHEAST SURFACE WINDS AND INCREASING CLOUD COVER
SHOULD HOLD HIGH TEMPERATURES IN THE 75 TO 80 DEGREE RANGE.
HUMIDITY LEVELS WILL ALSO BE QUITE COMFORTABLE.

MONDAY NIGHT...
THE BEST CHANCE OF RAIN SHOWERS AND ISOLATED THUNDER APPEARS TO BE
MONDAY NIGHT AS THE SHORTWAVE WORKS ACROSS THE REGION.  WILL GO WITH
LIKELY POPS IN THE FORECAST.  AS WE MENTIONED...SURFACE INSTABILITY
LOOKS QUITE LIMITED SO NOT EXPECTING SEVERE WEATHER.  SHOWALTER
INDICES ARE BELOW 0 AND WITH DECENT LOW LEVEL JET COULD SEE SOME
EMBEDDED THUNDER...SO WILL INCLUDE ISOLATED WORDING IN THE
FORECAST.  THE PWAT VALUES ARE BETWEEN 1.5 AND 2 INCHES SO BRIEF
LOCALLY HEAVY RAINFALL WILL BE POSSIBLE WITH THE ACTIVITY.

TUESDAY...
DRIER MID LEVEL AIR WILL WORK INTO THE REGION EARLY TUESDAY MORNING
CUTTING OFF THE BULK OF THE SHOWER ACTIVITY.  THEREFORE...MUCH OF
TUESDAY WILL PROBABLY END UP DRY WITH PARTIAL SUNSHINE.
HOWEVER...SHORTWAVE/COLD POOL ALOFT WILL ALLOW LAPSE RATES TO
STEEPEN.  THEREFORE...WHILE THE MAJORITY OF THE DAY WILL BE DRY...A
FEW POPUP SHOWERS AND PERHAPS AN ISOLATED THUNDERSTORM OR TWO MAY
RE-DEVELOP.  WILL INCLUDE SOME LOW CHANCE POPS TO COVER THIS
POTENTIAL.  HIGHS SHOULD BE IN THE UPPER 70S TO LOWER 80S.

WEDNESDAY THROUGH FRIDAY...
UPPER LEVEL TROUGH INITIALLY OVER NEW ENGLAND WILL MOVE EAST
ALLOWING FOR RISING HEIGHTS OVER THIS TIME.  THIS WILL ALLOW A
RETURN TO WARMER AND MORE HUMID WEATHER TO THE REGION.  WE ARE NOT
EXPECTING THE MAGNITUDE OF HEAT AND HUMIDITY THAT WERE CURRENTLY
EXPERIENCING.  NONETHELESS...HIGHS SHOULD CLIMB WELL INTO THE 80S TO
LOWER 90S BY THE END OF THE WORK WEEK.

AS FOR PRECIPITATION CHANCES...TRYING TO FORECAST THEM THIS FAR OUT
IS ALWAYS CHALLENGE ESPECIALLY THIS TIME OF YEAR WHEN EVERYTHING IS
CONVECTIVELY DRIVEN.  IT APPEARS THERE WILL BE SOME INSTABILITY THU
AND FRI WITH PERHAPS A FRONTAL BOUNDARY IN THE REGION.
THEREFORE...WILL SHOW 20 TO 30 POPS FOR THE RISK OF A FEW
SHOWERS/THUNDERSTORMS OVER THIS PERIOD. CERTAINLY NOT EXPECTING A
WASHOUT AND THE MAJORITY OF THIS TIME FRAME WILL LIKELY END UP DRY.

&&

.AVIATION /14Z SATURDAY THROUGH WEDNESDAY/...
FORECASTER CONFIDENCE LEVELS...
  LOW...LESS THAN 30 PERCENT
  MODERATE...30 PERCENT TO 60 PERCENT
  HIGH...GREATER THAN 60 PERCENT

HIGH CONFIDENCE IN TAFS WITH VFR THROUGH TAF PERIOD.

TODAY...HIGH CONFIDENCE IN MAINLY VFR.  SCATTERED SHOWERS AND
EMBEDDED THUNDERSTORMS WILL AFFECT MHT THROUGH 12 OR 13Z THIS
MORNING...WITH PERHAPS BRIEF MVFR CONDITIONS.  LOW PROBABILITY OF
THIS ACTIVITY AFFECTING THE BOS/ORH TERMINALS THROUGH 13Z...BUT ODDS
FAVOR IT STAYING JUST NORTH OF THESE SITES.  ALSO...MVFR
VISIBILITIES ON THE CAPE/ISLANDS EARLY THIS MORNING SHOULD IMPROVE
TO VFR.  THE EXCEPTION MIGHT BE NANTUCKET WHERE MARGINAL MVFR
VISIBILITIES IN HAZE COULD PERSIST INTO THE AFTERNOON.

THERE ALSO IS A LOW PROBABILITY OF AN AFTERNOON/EVENING THUNDERSTORM
SOUTH OF THE PIKE.  AT THIS TIME...ANY ACTIVITY THAT IS ABLE TO FORM
WOULD PROBABLY BE FAIRLY ISOLATED.

TONIGHT AND SUNDAY...HIGH CONFIDENCE IN MAINLY VFR CONDITIONS.
MARGINAL MVFR VISIBILITIES IN PATCHY FOG ARE POSSIBLE ACROSS ACK
TONIGHT AND PERHAPS BRIEFLY AT THE FMH/HYA TERMINALS.

KBOS TERMINAL...HIGH CONFIDENCE IN TAF. NO SEA BREEZE TODAY WITH
INCREASING W WIND /240-270/ LATER THIS MORNING.  LOW PROBABILITY OF
A SHOWER OR THUNDERSTORM THROUGH 13Z...BUT ODDS FAVOR ACTIVITY
STAYING NORTH OF THE TERMINAL

OUTLOOK...SUNDAY NIGHT THROUGH WEDNESDAY...

MEDIUM TO HIGH CONFIDENCE IN MAINLY VFR CONDITIONS.  THE EXCEPTION
WILL BE LATE MON AND MON NIGHT WHEN SHOWERS AND POSSIBLY ISOLATED
THUNDERSTORMS WILL BRING A PERIOD OF MVFR-IFR CONDITIONS.

&&

.MARINE...
WINDS AND SEAS EXPECTED TO REMAIN BELOW SCA THROUGH SUN. W WINDS
TODAY SHIFT TO N TONIGHT AS COLD FRONT CROSSES SOUTHERN NEW
ENGLAND. WEAK GRADIENT SUN WILL SUPPORT AFTERNOON SEA BREEZES.

PATCHY MORNING FOG WILL GIVE WAY TO HAZY CONDITIONS ON WATERS THIS
AFTERNOON...ESPECIALLY NEAR S COAST. POTENTIAL FOR ISOLATED
SHOWERS/STORMS LATER TODAY AND THIS EVENING ON S COASTAL
WATERS...MAINLY NEAR BLOCK ISLAND.

OUTLOOK...SUNDAY NIGHT THROUGH WEDNESDAY...

AS IS OFTEN THE CASE THIS TIME OF YEAR...THE PRESSURE GRADIENT WILL
BE WEAK ENOUGH TO KEEP WINDS AND SEAS BELOW SCA THRESHOLDS THROUGH
THE PERIOD.  THE MAIN CONCERN WILL BE THE CHANCE FOR ISOLATED
THUNDERSTORMS OVER THE WATERS MONDAY NIGHT.

&&

.CLIMATE...
SOME LONG STANDING RECORDS HIGHS WERE BROKEN FRIDAY...INCLUDING THE
ALL TIME RECORD HIGH FOR THE HARTFORD AREA.

BOS...103 TIED RECORD IN 1926
BDL...103 SET RECORD. PREVIOUS WAS 101 IN 1926
PVD...101 SET RECORD. PREVIOUS WAS 100 IN 1926
ORH... 96 DID NOT BREAK RECORD OF 99 SET IN 1926
