AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE TAUNTON MA
509 PM EDT WED MAY 29 2013

.SYNOPSIS...
THUNDERSTORMS ARE POSSIBLE LATE THIS AFTERNOON WITH A WARM FRONT
WEST OF THE CONNECTICUT RIVER. EXPECT HAZY...HOT AND HUMID
CONDITIONS STARTING TOMORROW AND LASTING INTO THE UPCOMING
WEEKEND AS HIGH PRESSURE SITS OFF THE EASTERN SEABOARD. A COLD
FRONT WILL SLOWLY APPROACH FROM THE WEST...BRINGING THE THREAT OF
SHOWERS AND THUNDERSTORMS FROM LATE SUNDAY AFTERNOON POSSIBLY INTO
TUESDAY. HIGH PRESSURE WILL BRING DRY CONDITIONS WITH MORE
SEASONABLE TEMPERATURES BY THE MIDDLE OF NEXT WEEK.

&&

.NEAR TERM /UNTIL 6 AM THURSDAY MORNING/...

*** SEVERE THUNDERSTORMS ARE POSSIBLE WEST OF THE CONNECTICUT
  RIVER LATE THIS AFTERNOON ***

430 PM UPDATE...SHOWERS AND THUNDERSTORMS HAVE DEVELOPED ACROSS
NEW YORK STATE WHERE THE SUN BROKE OUT THIS AFTERNOON. SBCAPE
VALUES IN THIS AREA HAVE JUMPED UP TO 1500 TO 2000 J/KG. SOME OF
THIS CAPE IS STARTING TO MOVE INTO WESTERN NEW ENGLAND...HOWEVER
ITS BALANCED BY SOME CONVECTIVE INHIBITION. WHILE WESTERN NEW
ENGLAND HAS SEEN SOME SUN...CLOUDS HAVE CREPT BACK OVER THE AREA.
THEREFORE...EXPECT ANY THUNDERSTORMS TO MOVE IN FROM EASTERN NEW
YORK STATE RATHER THAN DEVELOP OVER WESTERN NEW ENGLAND. THE LATER
IN THE DAY WE GET...THE LESSER THE OPPORTUNITY TO DEVELOP SHOWERS
AND THUNDERSTORMS. EXPECT MOST ACTIVITY TO BE LIMITED TO AREAS
WEST OF THE CONNECTICUT RIVER.

THERE IS ENOUGH INSTABILITY WEST OF THE CONNECTICUT RIVER THAT ANY
STORMS WILL BECOME SEVERE.  PWAT VALUES ARE OVER AN INCH SO ANY
STORM HAS THE POTENTIAL OF BEING A HEAVY RAINER WITH THE POTENTIAL
FOR URBAN AND POOR DRAINAGE FLOODING.  WITH 35 TO 45 KNOTS OF
EFFECTIVE BULK SHEAR...DAMAGING WINDS ARE LIKELY WITH ANY OF THESE
STORMS. THERE IS ALSO SUFFICIENT TURNING OF THE WINDS THAT THERE IS
THE POSSIBILITY OF AN ISOLATED TORNADO.  AGAIN...THERE IS SOME
UNCERTAINTY WITH WHETHER THE STORMS MAKE IT INTO WESTERN NEW ENGLAND.

TONIGHT...MID-LEVEL LAPSE RATES ARE STEEP ENOUGH THAT ANY SHOWERS
AND THUNDERSTORMS MAY BE ABLE TO SUSTAIN THEMSELVES INTO THE
OVERNIGHT.  HOWEVER...EXPECT THE BIGGEST THREAT TO BE HEAVY RAIN AND
THE POSSIBILITY OF URBAN AND POOR DRAINAGE FLOODING.  RAIN SHOULD
DIMINISH THROUGH THE NIGHT AND THE COMBINATION OF THE WET GROUND AND
DEWPOINTS IN THE 60S WILL RESULT IN PATCHY FOG ACROSS MUCH OF THE
AREA.  THESE HIGH DEWPOINTS WILL ALSO KEEP LOW TEMPERATURES IN THE
LOW 60S.

&&

.SHORT TERM /6 AM THURSDAY MORNING THROUGH THURSDAY NIGHT/...
THURSDAY WILL BE THE FIRST DAY IN A POSSIBLE HEAT WAVE.  AN UPPER
LEVEL RIDGE CENTERED OVER THE SOUTHEASTERN U.S. BUILDS INTO THE
NORTHEAST.  850MB TEMPS CLIMB TO 15-16C WHICH WITH STEEP MID LEVEL
LAPSE RATES WILL TRANSLATE TO TEMPERATURES CLIMBING INTO THE UPPER
80S TO LOWER 90S ACROSS SOUTHERN NEW ENGLAND.  DOWNSLOPING...
WESTERLY WINDS AND MOSTLY SUNNY TO SUNNY SKIES WILL AID IN BRINGING
TEMPERATURES UP.  TO BE A HEAT WAVE WE NEED THREE CONSECUTIVE DAYS
WITH TEMPERATURES GREATER THAN 90 DEGREES.  THE LAST TIME EACH OF
THE FOUR CLIMATE SITES HAD A HEAT WAVE IS LISTED IN THE CLIMATE
SECTION BELOW.

THURSDAY NIGHT WILL BE A REPEAT OF TONIGHT...LESS THE RAIN.  WITH
DEWPOINTS IN THE UPPER 50S TO LOWER 60S...EXPECT LOWS TO BE ABOUT
THE SAME OR A FEW DEGREES HIGHER.  AND WITH THE AMOUNT OF
MOISTURE...FOG IS LIKELY TO DEVELOP ONCE AGAIN.

&&

.LONG TERM /FRIDAY THROUGH WEDNESDAY/...

OVERVIEW AND MODEL PREFERENCES...

MEDIUM RANGE MODEL SUITE IN GOOD AGREEMENT INTO EARLY NEXT WEEK AT
LEAST ACROSS THE CONTIGUOUS U.S.  NOTING UPPER LEVEL CUTOFF LOW PRES
ACROSS THE CENTRAL AND UPPER PLAINS STATES WITH LARGE UPPER LEVEL
RIDGE ACROSS THE EAST LATE THIS WEEK. APPEARS THAT THE CUTOFF
MIDWEST LOW WILL SLOWLY FLATTEN AS UPPER LEVEL RIDGE SLOWLY BREAKS
DOWN NEXT WEEKEND. THIS WILL ALLOW SLOW MOVEMENT OF LONG WAVE TROUGH
EASTWARD EARLY NEXT WEEK. MAY SEE PERIOD OF SCATTERED SHOWERS/TSTMS
AS COLD FRONT SLOWLY MOVES ACROSS REGION AROUND THE LATE SUNDAY TO
TUESDAY TIMEFRAME...WITH IMPROVEMENT BY THE MIDDLE OF NEXT WEEK.
TIMING IS SUSPECT THOUGH AS MODELS TEND TO TRY TO BREAK DOWN
AMPLIFIED UPPER PATTERNS TOO QUICKLY.

PLAN ON USING BLEND OF PREVIOUS FORECAST WITH 12Z GFS/00Z ECMWF
/WHICH WERE IN VERY GOOD AGREEMENT INTO EARLY NEXT WEEK/ ALONG WITH
WPC GUIDANCE. FEEL THIS WILL TAKE INTO ACCOUNT SOME TIMING ISSUES
ESPECIALLY AFTER SUNDAY WITH FRONT APPROACH.

THE DAILIES...

FRIDAY-SATURDAY...WITH LONG WAVE RIDGE AND BERMUDA HIGH PRES IN
PLACE ALONG THE EASTERN SEABOARD...WILL SEE HAZY...HOT AND HUMID
CONDITIONS IN PLACE WITH GOOD SW GRADIENT IN PLACE ON FRIDAY AND
SATURDAY. HIGHS MAINLY IN THE LOWER-MID 90S BOTH DAYS...EXCEPT
COOLER ALONG THE S FACING COAST...CAPE COD AND THE ISLANDS.

ON FRIDAY...MAY SEE SCT SHOWERS/ISOLD TSTMS IN ANY CONVECTION THAT
MAY DEVELOP IN THE W-NW FLOW ALOFT AND MOVE ACROSS THE REGION FRI
AFTERNOON-EVENING. INSTABILITY IN PLACE WITH LI/S MAINLY BELOW ZERO
AND TOTAL TOTALS AROUND 50...MAINLY FROM THE MASS PIKE NORTHWARD.
SATURDAY WILL BE BREEZY ESPECIALLY ALONG THE S COAST WITH INCREASING
SW GRADIENT AHEAD OF APPROACHING COLD FRONT. MAY SEE WIDELY SCT
SHOWERS/TSTMS ACROSS S NH/N CENTRAL-W MA INTO N CENTRAL CT DURING
SAT AFTERNOON. MENTIONED ON THE GRIDS BUT THINK MAIN ACTION WILL
HOLD OFF UNTIL SUNDAY AT EARLIEST.

SUNDAY...WILL SEE COOLER TEMPS MAINLY DUE TO INCREASING CLOUDS AS
COLD FRONT STARTS ITS APPROACH. EXPECT SCT SHOWERS/TSTMS TO MOVE IN
DURING THE AFTERNOON FROM NW-SE...HOLDING OFF ACROSS EASTERN AREAS
UNTIL SUN NIGHT. HIGHS WILL BE MAINLY IN THE MID 70S TO LOWER
80S...COOLEST ALONG S COAST...CAPE COD AND ISLANDS.

VERY GOOD DYNAMICS IN PLACE WITH TOTAL TOTALS IN THE LOWER 50S...K
INDICES IN THE LOW 30S AND LI/S WELL BELOW ZERO. ALSO EXPECT SW LL
JET TO MOVE IN SUN AFTERNOON-NIGHT WITH H925 WINDS INCREASING TO 40-
50 KT...HIGHEST ACROSS RI/SE MA. WILL ALSO SEE VERY HIGH PWATS MOVE
ACROSS WITH THE FRONT...ON ORDER OF 1.75 TO 1.9 INCHES...SO COULD
SEE SOME HEAVY DOWNPOURS IN SOME PRECIP AREAS WHICH COULD CAUSE
LOCALIZED FLOODING. WITH ALL FACTORS IN PLACE...COULD SEE SOME
STORMS APPROACH SEVERE CRITERIA.  SOMETHING TO MONITOR CLOSELY.

MONDAY...COLD FRONT WILL SLOWLY MOVE ACROSS REGION DURING THE DAY AS
UPPER LEVEL SYSTEM PUSHES INTO NY STATE. BEST DYNAMICS MOVE
OFFSHORE...BUT COULD STILL SEE SOME CONVECTION AS FRONT PASSES. HAVE
CARRIED CHC SHOWERS/TSTMS THROUGH THE DAY INTO THE EVENING...THEN
SHOULD MOVE OFFSHORE MON NIGHT.

TUESDAY...SOME SHOWERS MAY LINGER ALONG THE E COAST EARLY TUE...
OTHERWISE EXPECT HIGH PRES TO BEGIN PUSHING E INTO NEW ENGLAND.
DRIER AND COOLER AIR WILL MOVE IN...WITH HIGHS MAINLY IN THE
LOWER-MID 70S.

WEDNESDAY...HIGH PRES BUILDS IN OUT OF CENTRAL CANADA AND THE GREAT
LAKES. HIGHS WILL BE IN THE LOWER-MID 70S.

&&

.AVIATION /21Z WEDNESDAY THROUGH MONDAY/...
FORECASTER CONFIDENCE LEVELS...

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

OVERVIEW...MODERATE CONFIDENCE.

MOSTLY IFR AND MVFR CONDITIONS IN LOW CLOUDS PARTICULARLY FROM THE
CONNECTICUT RIVER EAST. EXPECT THIS TO IMPROVE FROM WEST TO EAST TO
MVFR AND THEN POSSIBLY TO VFR THIS AFTERNOON. ANY BREAKS IN THE
CLOUDS THIS AFTERNOON WILL ALLOW FOR SHOWERS/TSTMS...PARTICULARLY
THROUGH THE WESTERN ZONES. STRONG WINDS...HEAVY RAIN AND SOME
HAIL ARE POSSIBLE WITH THESE STORMS. THE STORMS DIMINISH IN THE
EVENING. FOG POSSIBLE AT MOST TERMINALS TONIGHT...WITH IMPROVEMENT
TO VFR DURING THE DAY ON THURSDAY. THEN FOG AGAIN POSSIBLE
THURSDAY NIGHT.

KBOS TERMINAL...MODERATE CONFIDENCE IN TAF. MVFR CIGS MAY IMPROVE
TO VFR THIS AFTERNOON. LOW PROBABILITY OF A THUNDERSTORM THIS
AFTERNOON.

KBDL TERMINAL...MODERATE CONFIDENCE IN TAF. VFR CONDITIONS THIS
AFTERNOON. SEVERE TSTMS ARE POSSIBLE DURING THE AFTERNOON INTO
EVENING HOURS.

OUTLOOK...FRIDAY THROUGH MONDAY...

FRIDAY...MODERATE CONFIDENCE. MAINLY VFR. MAY SEE LOCAL MVFR
CIGS/VSBYS IN ISOLD SHOWERS/TSTMS THAT MAY DEVELOP/MOVE ACROSS
REGION FROM NW-SE. POCKETS OF LATE NIGHT/EARLY MORNING FOG WITH IFR
VSBYS.

SATURDAY...MODERATE CONFIDENCE. MAINLY VFR. MAY SEE ISOLD
SHOWERS/TSTMS ACROSS S NH/N AND W MA DURING THE AFTERNOON AND NIGHT
WITH LOCAL MVFR CIGS/VSBYS. AGAIN WILL SEE

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

SMALL CRAFT ADVISORIES ARE UP FOR THE SOUTHERN OUTER WATERS FOR SEAS
GREATER THAN 5 FEET.  SEAS WILL DIMINISH THURSDAY AFTERNOON AND
NIGHT AS THE RIDGE BUILDS OVER THE WATERS.  SOUTHWESTERLY WINDS
SHIFT TO THE WEST ON THURSDAY BUT WILL REMAIN BELOW 25 KTS.
SHOWERS...THUNDERSTORMS...AND FOG WILL LIMIT VISIBILITIES AT TIMES
THIS EVENING AND TONIGHT.  FOG WILL LIMIT VISIBILITIES THURSDAY
NIGHT AS WELL.

OUTLOOK...FRIDAY THROUGH MONDAY...

FRIDAY THROUGH SUNDAY...MODERATE CONFIDENCE. SW WINDS WILL CONTINUE.
EXPECT WINDS TO INCREASE BEGINNING SATURDAY AFTERNOON AS LOW LEVEL
JET INCREASES. EXPECT SMALL CRAFT CONDITIONS SAT-SUN...AND MAY SEE
GUSTS CLOSE TO GALE SUN NIGHT MAINLY ON THE SOUTHERN OUTER WATERS.
SCT SHOWERS/TSTMS WILL DEVELOP LATE SUN-SUN NIGHT ALONG WITH PATCHY
FOG WHICH WILL REDUCE VSBYS.

MONDAY...LOW TO MODERATE CONFIDENCE MAINLY DUE TO TIMING OF FRONT.
SMALL CRAFT WINDS/SEAS CONTINUE...THEN START TO DIMINISH MON NIGHT
