AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE TAUNTON MA
132 PM EDT WED JUN 1 2011

.SYNOPSIS...
WARM AND HUMID CONDITIONS RETURN TODAY AHEAD OF AN APPROACHING
COLD FRONT. THIS WILL BRING SCATTERED THUNDERSTORMS...MAINLY
TO INTERIOR SOUTHERN NEW ENGLAND WHERE SOME STORMS MAY BE STRONG
TO SEVERE. THE FRONT WILL PUSH OFFSHORE TONIGHT WITH A COOLER
AIRMASS OVERSPREADING THE REGION THURSDAY AND FRIDAY ALONG WITH
DRY CONDITIONS. MAINLY DRY WEATHER ALONG WITH TEMPERATURES AT OR
SLIGHTLY BELOW NORMAL SHOULD PERSIST INTO THE WEEKEND AND EARLY
NEXT WEEK.

&&

.NEAR TERM /UNTIL 6 PM THIS EVENING/...
LINE OF THUNDERSTORMS WITH HAIL UP TO 3/4 INCH DEVELOPED ACROSS E
MA/S NH EARLY THIS MORNING. SHOWERS/TSTMS MOVING ACROSS E COASTAL
MA/E RI THROUGH AROUND 15Z AS THEY EXIT THE COAST.

PREVIOUS DISCUSSIONS...
NOT MUCH CHANGE FROM PREVIOUS FORECAST. LINE OF CONVECTION ACROSS
NY STATE FIRING ON WARM FRONTAL BOUNDARY AND ON THE NOSE OF LOW-
MID LEVEL JET APPROACHING FROM ONTARIO. STORMS ARE BEGINNING TO
SHOW SIGNS OF WEAKENING AS LINE OF CONVECTION OUT RUNS GREATEST
DEEP LAYER SHEAR FARTHER TO THE WEST. THUS THESE STORMS WILL
LIKELY WEAKEN INTO A BROKEN LINE OF SHOWERS BY 8-9 AM ACROSS
WESTERN MA AND SOUTHWEST NH.

OTHER ITEM IS AREA OF DENSE FOG ACROSS LONG ISLAND/CT AND NOW
ADVECTING INTO RI WITH PVD DOWN TO 1/4 MILE. EXPECT THIS FOG TO
BURN OFF LATER THIS MORNING AS STRONG JUNE SUNSHINE GOES TO WORK
IN THE ABSENCE OF MID AND HIGH CLOUDS. PREVIOUS DISCUSSION BELOW.

SIGNIFICANT CHALLENGES OVER THE NEXT 12 HRS CONCERNING THE
CONVECTIVE POTENTIAL ALONG AND AHEAD OF A SFC COLD FRONT. LETS BEGIN
WITH THE STRAIGHT-FORWARD DETAILS...S/SW FLOW WILL INCREASE AHEAD OF
THE COLD FRONT WITH ANTICIPATED GUSTS AROUND 25 MPH ADVECTING VERY
WARM...MOIST AND SULTRY AIR ACROSS THE RGN...WITH DEWPOINTS RANGING
AROUND THE MID 60S. ANTICIPATING CONVECTIVE DEBRIS OUT OF THE GRT
LKS RGN TO DISSIPATE THANKS IN PART TO THE INFLUENTIAL SFC RIDGE OF
HIGH PRES GRADUALLY SLINKING SEWD...THOUGH THIS MAY NOT BE THE
CASE ACROSS UPSTATE NY INTO NRN NEW ENGLAND WHERE BETTER DYNAMICS
RESIDE. IN ADDITION PRESENT LOW CLOUDS ACROSS SRN NEW ENGLAND TO
MIX OUT AFTER SUNRISE...AS SUCH WOULD EXPECT AN ABUNDANCE OF
SUNSHINE...AND H925 TEMPS AVERAGING AROUND +22C AHEAD OF THE COLD
FRONT...TO ALLOW SFC TEMPS TO RISE INTO THE MID TO UPR 80S ACROSS
THE INTERIOR...WITH SOME LOCALES CLOSE TO 90...WHILE CLOSER TO
SHORE UPR 70S TO LOW 80S EXPECTED. YET...FOR THE MORNING
PERIOD...THERE IS STILL SOME LEVEL OF UNCERTAINTY AS THE MID-LVL
WARM FRONT LIFTS THRU THE RGN COUPLED WITH A REGION OF STRONG
MOIST CONVERGENCE AND ISENTROPIC LIFT AIDED BY STRONG SW FLOW...SO
CANT RULE OUT THE POTENTIAL FOR SOME DEVELOPING MID-LVL DECKS OUT
OF THE SW THRU THE MORNING PERIOD. THIS SW FLOW WILL ALSO ADVECT
MUCH WARMER AIR ACROSS THE RGN...AS PREV MENTIONED WITH THE +22C
AIR AT H925...ACTING TO EFFECTIVELY CAP THE LLVLS.

NOW TO SHIFT FOCUS TOWARDS THE PRESENT THINKING FOR TODAYS
CONVECTIVE OUTCOMES. WITH AFOREMENTIONED INVERSION HOVERING AROUND
H9...NOT ABSOLUTELY CONFIDENT THAT SFC TEMPS WILL WARM EFFECTIVELY
TO ALLOW FOR SFC BASED CONVECTION...RATHER FEEL ANY CONVECTION WILL
BE ELEVATED...OR RATHER FORCED BY THE APPROACHING COLD FRONT. CAPE
VALUES AVERAGE AROUND 2500 J/KG BY AFTN AS LAPSE RATES AT MID-LVLS
WILL BE FAIRLY STEEP AND WILL CONTINUE TO SEE STRONG THETAE
ADVECTION IN THE VICINITY OF THE H9 INVERSION. CAPE ITSELF...PER MDL
SKEW-T SOUNDINGS...STILL APPEARS TO BE FAIRLY TALL AND SKINNY
EMPHASIZING THE POTENTIAL FOR ENTRAINMENT OF DRIER AIR FROM THE
DEPARTING RIDGE OF HIGH PRES...AND WHETHER UPDRAFTS WILL MAINTAIN.
ALSO FEEL THE POSSIBILITY FOR LARGE HAIL WILL BE REDUCED AS SUCH. AS
TO SHEAR...BETTER DYNAMICS RESIDE WITH THE MAIN SHRTWV MAX AND
ATTENDANT H3 JET STREAK ACROSS NRN NEW ENGLAND. NEVERTHELESS 0-6KM
BULK SHEAR VALUES AVERAGE AROUND 40 KTS ACROSS THE FCST RGN...WITH
AN AVERAGE 30 KT FLOW AT 0-3 KM...AND DIRECTIONAL SHEAR FOR BOTH
LEVELS HAS A SUBSTANTIAL PERPENDICULAR COMPONENT TO THE SFC COLD
FRONT SUPPORTING A MORE DISCREET OUTCOME OVER A CONGLOMERATING
SQUALL-LINE SOLN...YET CANT RULE OUT THE DEVELOPMENT OF A
SQUALL-LINE LATE IN THE PERIOD. BOTH MDL SOUNDING HODOGRAPHS AND
0-1/0-3 KM HELICITY VALUES OF 200 M2/S2 SUPPORT THE POTENTIAL FOR
SUSTAINABLE ROTATING UPDRAFTS.

SO TAKING ALL POINTS INTO ACCOUNT...FEEL THERE IS STILL A FAIRLY
GOOD LIKELIHOOD OF A SEVERE WEATHER OUTCOME ALONG AND AHEAD OF THE
SFC COLD FRONT AS OUTLINED BY THE LATEST SPC DAY 1 CONVECTIVE
OUTLOOK. MAIN THREATS FOR TODAY WILL BE SMALL HAIL...FREQUENT
LIGHTNING...AND MOST IMPORTANTLY DAMAGING WINDS AS THERE IS LIKELY
TO BE STRONG MID-LVL SW FLOW RANGING AROUND 50 MPH THAT CAN EASILY
MIX DOWN TO THE SFC PER A STRONG DOWNWARD CORE OF PRECIP. WILL NEED
TO WATCH FOR PSBL LOCALIZED FLOODING FROM STRONG STORMS AS PWATS
ACROSS THE RGN WILL AVERAGE AROUND 1.5 INCHES. BETTER CHCS FOR
SEVERE WEATHER WILL LIKELY BE ACROSS THE INTERIOR AS COOLER MORE
STABLE AIR WILL BE PRESENT OVER SE NEW ENGLAND. MOST OF THE
CONVECTION WILL LIKELY OCCUR BEGINNING AROUND THE MIDDAY PERIOD INTO
THE AFTN.

&&

.SHORT TERM /6 PM THIS EVENING THROUGH 6 PM THURSDAY/...
*TONIGHT...
SFC COLD FRONT WILL SLIDE OFFSHORE AND MOST OF THE CONVECTION SHOULD
DISSIPATE AS LLVLS COOL AND ELEVATED CONVECTION CHCS DISSIPATE AS
DRIER AIR AND HIGH PRES QUICKLY MOVE IN AT THE LOW LVLS IN WAKE OF
THE FRONT. STRONG CAA WILL ALSO PREVAIL WITH H925 TEMPS FALLING TO
AN AVERAGE OF +10C OVER THE FCST RGN WITH WINDS SHIFTING OUT OF THE
W/NW. WENT WITH THE COOLER SIDE OF MOS GUIDE WITH MINS FALLING INTO
THE LOW TO MID 50S THRU THE INTERIOR...WARMER TOWARDS THE SHORE.

*THURSDAY...
A CONSIDERABLY COOLER DAY AS HIGH PRES CONTINUES TO BUILD INTO THE
RGN WITH MUCH COOLER AIR. WITH COOLING AT MID-LVLS THIS WILL ACT TO
LOWER HEIGHTS RESULTING IN THE DEPARTING UPR LVL LOW AND ASSOC
VORTMAX TO DIG SWD THRU THE RGN. WILL SEE ATTENDANT CYCLONIC FLOW
AND COOL/MOIST AIR TO SPILL OVER THE RGN ALONG WITH AN ASSOC H3 JET
MAX SUPPORTING DIVERGENCE OVER THE RGN. AS SUCH ANTICIPATE THE
DEVELOPMENT OF A DENSE STRATOCU LAYER OVER THE RGN LIKELY LENDING TO
DECREASED WARMING THRU THE DAY...COULD POTENTIALLY SEE A COOLING
TREND...UNDER STRONG NW FLOW GUSTING AT TIMES 25 TO 30 MPH. CANT
RULE OUT THE POTENTIAL FOR DRIZZLE/LIGHT RAIN ESPECIALLY ALONG
HIGHER TERRAIN WHERE OROGRAPHIC FORCING WILL PLAY A SIGNIFICANT
ROLE. HAVE GONE WITH THE VERY LOW END OF MOS GUIDANCE WITH MAX TEMPS
RANGING IN THE LOW TO MID 60S FOR THE N/NW FCST RGN...WITH LOW 70S
ALONG THE SHORE.

&&

.LONG TERM /THURSDAY NIGHT THROUGH TUESDAY/...
HIGHLIGHTS...

* MAINLY DRY WEATHER WITH TEMPERATURES AT OR SLIGHTLY BELOW NORMAL
MUCH OF THIS PERIOD.

MODEL PREFERENCES...
VERY GOOD MODEL AGREEMENT AMONG THE ECMWF/ECENS...NAM AND GFS ON
THE LARGE SCALE FLOW THIS PERIOD WITH THE CURRENT EASTERN WARM
CORE RIDGE BEING REPLACED BY A COOLER LONG WAVE TROF SETTING UP
OVER SOUTHEAST CANADA. HOWEVER ALL MODEL GUIDANCE KEEPS THIS NEW MID
LEVEL MEAN TROF AXIS EAST OF NEW ENGLAND...PROMOTING MAINLY DRY
WEATHER. BY SUNDAY THE ECMWF AND GFS BEGIN TO DIFFER WITH THE
ECMWF AND ITS ENSEMBLES FARTHER EAST WITH THE SOUTHEAST CANADA
TROF...WHILE THE 00Z GFS IS FARTHER WEST WITH THIS TROF AND
SUGGEST COMMAHEAD/TROWAL PRECIP FROM THE MARITIMES POSSIBLY
ROTATING INTO NEW ENGLAND SUN/MON. GIVEN THE GEFS AND THE 50
MEMBER ENSEMBLE MEAN OF THE ECENS SUPPORTS THE DRY SOLUTION OF THE
OPERATIONAL ECMWF...WILL LEAN TOWARD DRY WX SUN/MON/TUE.

THE DAILY DETAILS...

THU NIGHT AND FRI...
SIGNIFICANT COOL DOWN WITH CLOSED LOW OVER THE MARITIMES CIRCULATING
A MUCH COOLER AIRMASS INTO SOUTHERN NEW ENGLAND WITH 850 TEMPS
CRASHING FROM +18C THIS AFTERNOON TO +1C THU NIGHT!  DEFINITELY A
TOUCH OF FALL IN THE AIR FRI MORNING WITH LOWS IN THE U30S AND
L40S...EXCEPT NEAR 50 IN THE URBAN AREAS. IN FACT THERE IS A LOW
PROBABILITY OF PATCHY FROST ACROSS THE CT RVR VLY OF WRN MA INTO
CHESHIRE COUNTY OF NH. AIRMASS DOES MODIFY TO ABOUT +5C FRI AFTN
/PER GEFS AND ECMWF/ COURTESY OF STRONG JUNE SUNSHINE. NEVERTHELESS
HIGHS FRI WILL ONLY CLIMB INTO THE U60S AND L70S...WHICH IS A FEW
DEGREES COOLER THAN NORMAL BUT MUCH LOWER TEMPS THAN RECENT DAYS.

SAT...
NOT MUCH CHANGE...NW FLOW ALOFT WITH CLOSED LOW REMAINING OVER THE
MARITIMES. PLEASANT DAY WITH SUNSHINE...LOW HUMIDITY AND 850 TEMPS
WARMING TO ABOUT +7C SUPPORTING HIGHS IN THE 70S INLAND.

SUN/MON AND TUE...
AS NOTED ABOVE MODELS BEGIN TO DIVERGE HERE WITH ECMWF AND ITS
ENSEMBLES FARTHER EAST WITH MARITIME LOW THAN GFS. GIVEN THE GEFS
AND THE ECENS SUPPORT THE OPERATIONAL ECMWF SOLUTION WILL LEAN
TOWARD A DRIER FORECAST HERE ALONG WITH CONTINUED TEMPS AT OR
SLIGHTLY BELOW NORMAL. FOR POPS THESE THREE DAYS WE FOLLOWED THE
LOWER HPC VALUES COMPARED TO THE HIGHER 00Z GMOS POPS.

.AVIATION /17Z WEDNESDAY THROUGH SUNDAY/...
FORECASTER CONFIDENCE LEVELS...
  LOW...LESS THAN 30 PERCENT
  MEDIUM...30 PERCENT TO 60 PERCENT
  HIGH...GREATER THAN 60 PERCENT

REST OF TODAY...
MEDIUM CONFIDENCE IN OVERALL TRENDS...LOW TO MEDIUM CONFIDENCE IN
EXACT TIMING. EXPECT GRADUALLY CLEARING SKIES THROUGH AROUND 20Z
OVER WRN TERMINALS...THEN 21Z OR LATER AT ERN TERMINALS. AFTER
THIS POINT A COLD FRONT WILL PUSH SCT TSTMS THROUGH THE REGION.
BEST TIMING WILL BE THE 20Z TO 22Z TIMEFRAME FOR TERMINALS W OF
ORH...THEN 21Z TO 23Z FOR TERMINALS E OF ORH. CANNOT RULE OUT
POTENTIAL FOR GUSTY WINDS AND HAIL WITH THESE STORMS. CBS WILL
LIKELY LINGER INTO THE EVENING HOURS. OTHERWISE WINDS WILL REMAIN
GUSTY OUT OF THE SSW.

TONIGHT...
REMNANT TSTMS DISSIPATE AFTER SUNSET. OTHERWISE...EXPECT SOME
LINGERING MVFR CIGS AND VSBYS IN -SHRA AND FOG. SUSPECT MOSTLY A
LIFT TO VFR AFTER COLD FROPA AFTER MIDNIGHT SAVE FOR MAYBE CAPE
AND ISLANDS WHICH MAY SEE A REMNANT MVFR CIG OR VSBY INTO THE
EARLY MORNING HOURS. WINDS GRADUALLY SHIFTING TO THE W AROUND 10
KTS OVERNIGHT.  MEDIUM CONFIDENCE.

THURSDAY...
HIGH CONFIDENCE VFR. EXPECT SCU DEVELOPMENT LATE MORNING AND
AFTERNOON WITH CIGS 4 OR 5 KFT. A POSSIBLE MVFR CIG OVER THE NW.

KBOS TERMINAL...
VFR TO CONTINUE FOR THE NEXT COUPLE OF HOURS THROUGH AROUND 21Z
WITH SSW WINGS GUSTING TO 25 KT ON OCCASION. AFTER THAT EXPECT
TSTM DEVELOPMENT NEAR OR OVER THE TERMINALS ESPECIALLY BETWEEN 21Z
AND 00Z. EXPECT MVFR AND IFR CIGS AND VSBYS WITH HEAVY
RAIN...GUSTY WINDS AND HAIL POSSIBLE WITH THESE STORMS. CONDITIONS
IMPROVE OVERNIGHT AFTER A COLD FRONT PUSHES THROUGH. EXPECT MOSTLY
VFR AFTER MIDNIGHT WITH WINDS SHIFTING THE W.

OUTLOOK...THURSDAY NIGHT THROUGH SUNDAY...

GENERALLY VFR THROUGH THE PERIOD. MODERATE TO HIGH CONFIDENCE.

&&

.MARINE...
WEDNESDAY...
HAVE EXTENDED SCA FOR MUCH OF THE AREA BEGINNING PRIOR TO MIDDAY
WITH ANTICIPATION OF INCREASING S/SW FLOW WITH GUSTS AT OR ABOVE
25 KTS...ESPECIALLY CLOSER TO SHORE...RESULTING IN BUILDING SEAS
OF 5-6 FEET INTO THE AFTN. OF CONSIDERABLE NOTE WILL BE THE
POTENTIAL FOR THUNDERSTORMS...SOME OF WHICH MAY BE SEVERE...ALONG
AND AHEAD OF A COLD FRONT WHICH WILL SWEEP INTO THE WATERS BY LATE
AFTN AND INTO THE EVNG.

WEDNESDAY NIGHT...
CONVECTIVE POTENTIAL WILL DISSIPATE AS COLD FRONT SWEEPS OFFSHORE.
SW WINDS TO SHIFT OUT OF THE W AND POTENTIALLY GUST AT TIMES
IMMEDIATELY IN WAKE OF THE COLD FRONT. WILL SEE A LULL IN THE
WINDS AFTERWARD TOWARDS MORNING...AND THERE IS THE POTENTIAL FOR
SEAS CLOSER TO SHORE TO FALL BELOW SCA THRESHOLDS...BUT FEEL
CONDITIONS WILL

THURSDAY...
CONTINUING SCA THRU THE WED NGT PD INTO THURS AS HIGH PRES BUILDS
INTO THE RGN AS A LOW PRES DIGS THRU ERN NEW ENGLAND...WILL SEE
STRONG W/NW WINDS GUSTING 25 TO 30 KTS AND SEAS BUILD TO 5-7 FEET
OVER THE WATERS.

OUTLOOK...THURSDAY NIGHT THROUGH SUNDAY...

THU NIGHT AND FRI...NW WINDS MAY GUSTS TO 25 KT ESPECIALLY NEAR
SHORE.

SAT AND SUN...LIGHTER WINDS AS WEAK HIGH PRES BUILDS OVER THE AREA
SAT FOLLOWED BY A BROAD/WEAK LOW PRES SUN.
