AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE TAUNTON MA
447 PM EDT TUE JUN 25 2013

.SYNOPSIS...
WARM AND MUGGY CONDITIONS WILL CONTINUE AS SHOWERS AND
THUNDERSTORMS BECOME MORE WIDESPREAD INTO THE END OF THE WEEK.
WHILE HEAVY RAIN WITH POTENTIAL LOCALIZED FLOODING IS THE PRIMARY
THREAT...STRONG THUNDERSTORMS WILL BE POSSIBLE AS A COLD FRONT
SLOWLY APPROACHES FROM THE WEST THIS WEEKEND INTO EARLY NEXT WEEK.

&&

.NEAR TERM /UNTIL 10 PM THIS EVENING/...
*** HEAT AND HUMIDITY CONTINUE INTO TODAY ***
*** THUNDERSTORMS WITH HEAVY DOWNPOURS POSSIBLE ***

2 PM UPDATE...TEMPERATURES ARE IN THE UPPER 80S AND LOWER 90S
ACROSS MUCH OF THE AREA...WITH MID 80S EVEN ON THE OUTER CAPE AND
MARTHAS VINEYARD. WHILE TEMPERATURES ARE DEFINITELY HOT...WE ARE
NOT IN DANGER OF HITTING THE RECORDS TODAY. BOTH BOSTON AND
HARTFORD HAVE HIT 90 DEGREES FOR THE THIRD DAY IN A ROW MAKING IT
AN OFFICIAL HEAT WAVE AT THOSE TWO SITES. OUR TWO OTHER OFFICIAL
CLIMATE STATIONS...WORCESTER AND PROVIDENCE...HAVE NOT YET HAD A
HEAT WAVE. WORCESTER HAS NOT HAD ANY HIGH TEMPERATURES OVER 90
DEGREES AND PROVIDENCE HAS HIT 90 DEGREES FOR ONLY THE SECOND DAY
IN A ROW.

THE CONVECTIVE TEMPERATURE ACROSS THE AREA IS ALSO IN THE UPPER
80S TO LOWER 90S SO SHOWERS AND THUNDERSTORMS ARE LIKELY TO
DEVELOP AS WE GO THROUGH THE AFTERNOON. STORMS HAVE ALREADY POPPED
ACROSS MUCH OF NEW YORK STATE AND PORTIONS OF NORTHERN NEW
ENGLAND. SPC MESOANALYSIS HAS UP TO 3000 J/KG OF SB CAPE ACROSS
MUCH OF THE AREA WITH LITTLE TO NO CONVECTIVE INHIBITION. LIKE
YESTERDAY... THERE IS VERY LITTLE SHEAR. BETWEEN THIS AND A LACK
OF A GOOD TRIGGER LIKE A SHORTWAVE OR A FRONT...EXPECT THE THREATS
FROM THESE STORMS TO MAINLY BE HEAVY RAIN AND FREQUENT LIGHTNING.
PRECIPITABLE WATER VALUES ARE FORECAST TO INCREASE TO BETWEEN 1.5
AND 2 INCHES WHICH IS 2 TIMES THE NORMAL. THERE IS A LOW
PROBABILITY OF STRONG WIND GUSTS TO 50 MPH AND PEA SIZE HAIL WITH
ANY OF THESE STORMS. THE HRRR MODEL STILL SHOWS A CONVECTIVE LINE
MOVING THROUGH SOUTHERN NEW ENGLAND BETWEEN 21-01Z. FROM JUST THE
INSTABILITY AND SHEAR AVAILABLE...WOULD HAVE LOW CONFIDENCE ON
THIS LINE DEVELOPING. HOWEVER...THE HRRR IS DOING A GREAT JOB WITH
THE CONVECTION ACROSS NEW YORK STATE SO TEND TO HAVE A BIT MORE
CONFIDENCE IN THAT MODELS SOLUTION. HIGHEST CONFIDENCE IS ACROSS
NORTHERN MASSACHUSETTS AND SOUTHERN NEW HAMPSHIRE CLOSER TO A WEAK
SHORTWAVE MOVING THROUGH QUEBEC.

&&

.SHORT TERM /10 PM THIS EVENING THROUGH WEDNESDAY NIGHT/...
TONIGHT...ANY LINGERING SHOWERS AND THUNDERSTORMS WILL DIMINISH
LATE TONIGHT. WILL BE ANOTHER WARM AND MUGGY NIGHT WITH LOW
TEMPERATURES IN THE UPPER 60S TO THE LOWER 70S. FOG IS A
POSSIBILITY AGAIN TONIGHT WITH THE BEST CHANCE ACROSS THE SOUTH
COAST...CAPE...AND ISLANDS.

WEDNESDAY...SHOWERS AND THUNDERSTORMS ARE LIKELY ONCE AGAIN. THERE
IS ACTUALLY A BETTER CHANCE WEDNESDAY THAN TODAY WITH A SHORTWAVE
MOVING ACROSS SOUTHERN NEW ENGLAND INCREASING SHEAR AND PROVIDING
A TRIGGER. THE HEAT AND HUMIDITY SHOULD CONTINUE WHICH WILL KEEP
CAPE VALUES HIGH. SO WITH PLENTY OF INSTABILITY...25 TO 30 KTS OF
SHEAR AND PLENTY OF MOISTURE WITH PWATS UP TO 2 INCHES...EXPECT
THUNDERSTORMS WITH HEAVY RAIN AND STRONG TO DAMAGING WINDS.

TEMPERATURES WILL BE A BIT COOLER...PARTICULARLY ACROSS THE
NORTHERN ZONES WHERE A BACK DOOR COLD FRONT MAY TRY TO EDGE IN.
EXPECT HIGHEST TEMPERATURES IN THE UPPER 80S TO LOW 90S ALONG AND
SOUTH OF THE MASS PIKE AND SLIGHTLY COOLER TEMPERATURES NORTH OF
THE MASS PIKE WITH HIGHS IN THE MID 80S.

WEDNESDAY NIGHT...COOLER TEMPERATURE TREND WILL CONTINUE WITH THE
BACK DOOR FRONT CONTINUING TO MOVE SOUTHWARD THROUGH SOUTHERN NEW
ENGLAND. EXPECT OVERNIGHT LOWS IN THE MID TO UPPER 60S. ANY
CONVECTION DURING THE DAY WILL LIKELY CONTINUE FOR MUCH OF THE
NIGHT WITH LIFT PROVIDED BY THE SHORTWAVE AND THE BACK DOOR FRONT.
HEAVY RAIN AND ANY URBAN AND POOR DRAINAGE FLOODING WILL BE THE
MAIN CONCERNS OVERNIGHT...THOUGH STRONG GUSTY WINDS AND SMALL HAIL
CANNOT BE RULED OUT. ONCE AGAIN...FOG IS LIKELY...PARTICULARLY
ALONG THE SOUTH COAST.

&&

.LONG TERM /THURSDAY THROUGH TUESDAY/...
HEADLINES...

* HEAVY RAIN THREAT PREVAILS THROUGH MOST OF THIS TIMEFRAME
* LOCALIZED URBAN AND LOW LYING AREA FLOODING IS A POSSIBILITY
* STRONG THUNDERSTORMS POSSIBLE THURSDAY
* CONTINUED WARM AND MUGGY CONDITIONS

OVERVIEW AND MODEL PREFERENCES...
MEDIUM RANGE MODELS CONTINUE TO SIGNAL HIGHLY ANOMALOUS UPPER
LEVEL BLOCKING PATTERN FOR EARLY SUMMER...WITH HIGH AMPLITUDE
RIDGE ACROSS THE WESTERN U.S. AND LONG WAVE TROUGH ACROSS THE E.
THIS WILL KEEP THE REGION IN A RELATIVELY UNSETTLED PATTERN THANKS
TO THE UPPER TROUGH/CUTOFF LOW NEAR OR TO THE W OF THE
REGION...THOUGH SOME MODELS ARE TRYING TO RETROGRADE THE TROUGH A
BIT FURTHER W LATE IN THE PERIOD /MON- TUE/ TO PUSH THREAT OF
SHOWERS FURTHER W. ALSO NOTING SOME BRIEF BREAKS IN THE
ACTION...MAINLY AROUND THE LATE THU-FRI TIMEFRAME AS SEEN ON 12Z
OP RUNS OF THE GFS/GGEM AND ECMWF. THIS IS JUST ONE
RUN...THOUGH...SO NOT VERY CONFIDENT. WILL STILL SEE PROLONGED
PERIOD OF WARM AND HUMID CONDITIONS.

WITH HIGH PWATS...ON THE ORDER OF 1.7 TO AROUND 2 INCHES WITH
PROLONGED S-SW FLOW IN PLACE...EXPECT ANY SHOWERS/TSTMS TO PRODUCE
LOCALLY HEAVY RAINFALL ESPECIALLY THU AND FRI. WILL NOT SEE A
COMPLETE WASHOUT...BUT MAY SEE PERIODS OF SHOWERS/TSTMS EACH DAY.
BY THIS WEEKEND...COULD SEE SOME GRADUAL IMPROVEMENT BUT THIS WILL
BE DEPENDENT UPON WHETHER THE TROUGH ACTUALLY RETROGRADE AS MODELS
ARE SUGGESTING.

LEANED TOWARD A BLEND OF THE PREVIOUS FORECAST WITH THE WPC
GUIDANCE...WHICH USED A BLEND OF THE GFS/ECMWF AND THEIR ENSEMBLE
MEANS. THIS GAVE GOOD CONTINUITY TO THE LAST SEVERAL FORECASTS.

DETAILS...

THURSDAY-FRIDAY...CONTINUED THREAT OF SHOWERS/TSTMS DURING THIS
TIMEFRAME. BEST INSTABILITY WILL BE ACROSS CENTRAL AND WESTERN
AREAS THU INTO FRI MORNING SO HAVE KEPT LIKELY POPS GOING THERE.
WILL ALSO SEE HEAVY RAINFALL AND POSSIBLE LOCALIZED FLOODING...
THOUGH TOUGH TO PINPOINT WHERE THESE WILL OCCUR. DURING THE DAY
FRIDAY INTO FRIDAY NIGHT...MAY SEE LESSER OF A CHANCE OF PRECIP
AS BRIEF LULL MOVES ACROSS. WITH HIGH HUMIDITIES...CAN NOT RULE
OUT THE CHANCE OF PRECIP THOUGH SO LEFT LOW CHANCE POPS GOING.
WILL ALSO SEE PATCHY FOG DEVELOP EACH NIGHT/EARLY MORNING
TIMEFRAME ESPECIALLY ALONG THE S COAST WITH SUCH MUGGY CONDITIONS
IN PLACE. MAY SEE GUSTY WINDS ALONG THE S COAST FRIDAY AS S-SW LOW
LEVEL JET SETS UP. GUSTS UP TO 25-30 KT POSSIBLE.

SATURDAY-TUESDAY...WILL SEE CONTINUED CHANCE POPS FOR MOST OF THIS
TIMEFRAME...THOUGH MAY SEE A SLOWLY LOWER CHANCE MON-TUE IF THE
MODELS VERIFY AND TRY TO RETROGRADE INSTABILITY AXIS TO THE W.
KEPT MENTION OF TSTMS MAINLY DURING THE DAYLIGHT HOURS THIS
WEEKEND...THEN MOVED IT W EARLY NEXT WEEK. LOW LEVEL JET IN PLACE
ON SAT MAY BRING GUSTS ALONG THE S COAST UP TO 25 KT.
