AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE TAUNTON MA
1036 AM EDT TUE JUN 23 2015

.SYNOPSIS...
THE POTENTIAL EXISTS FOR A SIGNIFICANT SEVERE WEATHER EVENT THIS
AFTERNOON AND EARLY EVENING...BUT WILL DEPEND ON HOW MUCH SUNSHINE
DEVELOPS AHEAD OF A COLD FRONT. CONVECTIVE WEATHER PUSHES OFFSHORE
TONIGHT. HIGH PRESSURE BUILDS INTO THE REGION FOR WEDNESDAY AND
THURSDAY...BRINGING SEASONABLE TEMPERATURES AND A PERIOD OF DRY
WEATHER. THE END OF THE WEEK AND THIS WEEKEND LOOK COOL AND RAINY
AT TIMES. DRIER CONDITIONS SHOULD RETURN EARLY NEXT WEEK.

&&

.NEAR TERM /UNTIL 6 PM THIS EVENING/...
*** A SEVERE THUNDERSTORM WATCH HAS BEEN ISSUED FOR ALL OF
 SOUTHERN NEW ENGLAND EXCEPT THE CAPE AND ISLANDS THROUGH 4 PM
 THIS AFTERNOON ***

1030 AM UPDATE...

A SEVERE THUNDERSTORM WATCH HAS BEEN ISSUED FOR ALL OF SOUTHERN
NEW ENGLAND EXCEPT THE CAPE AND ISLANDS THROUGH 4 PM THIS
AFTERNOON. THIS WATCH IS NOT JUST FOR THE THUNDERSTORMS MOVING
INTO WESTERN MASSACHUSETTS AND CONNECTICUT AT THIS TIME BUT ALSO
FOR STORMS DEVELOPING LATER THIS AFTERNOON WITH THE COLD FRONT.

WHILE THERE IS STILL QUITE A BIT OF CLOUD COVER OVER MUCH OF
SOUTHERN NEW ENGLAND...THERE IS CLEARING BEHIND THIS FIRST ROUND
OF THUNDERSTORMS. THIS WILL ALLOW FOR SOME DESTABILIZATION BEFORE
STORMS DEVELOP ALONG THE FRONT LATER THIS AFTERNOON. SPC
MESOANALYSIS PAGE INDICATES AT LEAST 500 J/KG OF CAPE OVER PARTS
OF SOUTHERN NEW ENGLAND CURRENTLY AND THIS IS EXPECTED TO INCREASE
AS THE AFTERNOON GOES ON AND WE GET SOME CLEARING INTO SOUTHERN
NEW ENGLAND.

MID LEVEL LAPSE RATES OVER WESTERN-CENTRAL PA AND NY ARE STEEP AT
7C/KM PER LATEST SPC MESOANALYSIS. THIS AIRMASS WILL CONTINUE
ADVECTING EASTWARD TOWARD THE REGION. IN ADDITION STRONG WIND
FIELDS CAN COMPENSATE IF INSTABILITY IS LACKING. THUS STILL
EXPECTING AN ACTIVE DAY OF STORMS ACROSS SOUTHERN NEW ENGLAND THIS
AFTERNOON AND INTO EARLY THIS EVENING ALONG THE SOUTH COAST.
EARLIER DISCUSSION BELOW.

=====================================================================

POTENT SHORTWAVE CONTINUES TO MOVE ACROSS THE GREAT LAKES AND ITS
ASSOCIATED COLD FRONT WILL MAKE ITS WAY TO THE NORTHEAST LATER
TODAY BRINGING THE POTENTIAL FOR SEVERE WEATHER ACROSS THE AREA
THIS AFTERNOON.

THIS AFTERNOON...

ONCE THE WEAKENED MCS MOVES THROUGH...AND THE WARM FRONT LIFTS
NORTHWARDS...SOUTHERN NEW ENGLAND WILL BE IN A VERY WARM...MOIST AND
UNSTABLE AIRMASS. IF CLOUDS BREAK LATER THIS MORNING/EARLY
AFTERNOON A FEW LOCATIONS HAVE THE POTENTIAL TO REACH UP TO 90
DEGREES. OTHERWISE EXPECT TEMPERATURES TO REACH INTO THE MID TO
UPPER 80S WITH DEWPOINTS NEAR 70F. MODEL GUIDANCE CONTINUES TO
PROG OVER 1500 J/KG OF MU CAPE ACROSS THE REGION THIS AFTERNOON.
THIS IS VERY CONSISTENT ACROSS ALL GUIDANCE INCLUDING THE
CONSERVATIVE EURO...SO THE MODELS MAY BE HINTING AT SOMETHING.

LIMITING FACTOR FOR TODAY...AS MENTIONED BY PREV FORECASTER IS THE
CLOUD DEBRIS POTENTIAL. SEVERAL COMPLEXES ACROSS THE MIDWEST WILL
CONTINUE TO MOVE EASTWARD...AND THERE IS A LOT OF UNCERTAINTY ON
WHETHER THEY WILL DISSIPATE OR STAY INTACT. SOME OF THE HI-RES
GUIDANCE SUGGESTS THAT WE WILL CLEAR OUT BY THE AFTERNOON
ALLOWING FOR STORMS TO FIRE...WHILE A FEW LIKE THE NAM/HRRR
SUGGEST THAT CLOUDS WILL STICK AND THESE COMPLEXES MOVE OVER
SNE...LIMITING OUR SEVERE WEATHER POTENTIAL. EITHER WHICH
WAY...FEEL THAT WE WILL NOT ESCAPE ISSUING A WARNING SOMETIME
TODAY GIVEN THE ROBUST DYNAMICS AND THERMO PROFILES.

OVERALL APPEARS THAT THE ATMOSPHERE WILL DESTABILIZE AS MOISTURE
STREAMS INTO THE AREA BEHIND THE WARM FRONT. ANTICIPATE STRONG
HEATING FROM ANY CLOUD BREAKS ALLOWING FOR INSTABILITY TO INCREASE
BETWEEN 1500-2500 J/KG. ALTHOUGH IT APPEARS THAT LOCATIONS SOUTH
OF NEW ENGLAND WILL HAVE THE HIGHER INSTABILITY...AS THEY ARE
EXPECTED TO HAVE LESS CLOUD DEBRIS...SNE MAKES UP FOR IT WITH THE
DEEP LAYER WIND PROFILE...AROUND 40-50 KTS OF SHEAR. THERE ALSO
SHOULD BE A PLUME OF A REMNANT EML WITH MID LEVEL LAPSE RATES IN
EXCESS OF 6.5 C/KM. ITS HARD TO LOCATE WHERE IT WILL BE
EXACTLY...SINCE IT APPEARS LOWER WHERE THE MODEL THINKS THERE IS
CONVECTION. IN ADDITION...0 TO 1 KM HELICITY VALUES ARE QUITE
IMPRESSIVE ON ALL THE MODELS. SO WITH A DECENT AMOUNT OF
CAPE...HIGH SHEAR AND APPROACHING COLD FRONT BELIEVE THAT STRONG
TO SEVERE THUNDERSTORMS WILL DEVELOP ACROSS NEW ENGLAND.

THE HIGHEST RISK WILL BE NEAR AND NORTHWEST OF A BOSTON TO
PROVIDENCE CORRIDOR...BUT WE CAN/T RULE OUT ACTIVITY MAKING IT ALL
THE WAY TO THE CAPE COD CANAL GIVEN STRONG FORCING. IN FACT...A LOT
OF THE LATEST GUIDANCE SHOWS QPF ACROSS THE CAPE AND THE ISLANDS
BY EARLY THIS EVENING. MAIN THREATS FROM THESE STORMS WILL BE
STRONG DAMAGING WIND GUSTS...LARGE HAIL...HEAVY RAINFALL...AND AN
ISOLATED TORNADO OR TWO. ALSO CANNOT UNDERPLAY THE LIGHTNING
RISK. PWAT VALUES DO CLIMB UP TO 2 INCHES WITH K VALUES ABOVE
40...SO ALTHOUGH THESE STORMS WILL BE MOVING QUICKLY...THIS COULD
BE A SCENARIO WHERE LOCATIONS COULD GET A QUICK INCH OF RAIN
WITHIN 20 MINS.

BEST TIMING IS HARD TO SAY AS WE WILL HAVE TO WAIT AND SEE WHEN/IF
THE CLOUDS BREAKUP BUT BELIEVE THAT BETWEEN 2-8 PM HAS THE BEST
POTENTIAL FOR SEVERE WEATHER TO OCCUR. ALSO THE MODE OF PRECIP
WILL BE TRICKY TO FORECAST. WE COULD SEE A FEW ISOLATED SEVERE
STORMS DEVELOP OUT AHEAD OF THE COLD FRONT...BUT ONCE THIS FRONT
APPROACHES THE REGION WE COULD SEE A LINE OF STORMS WITH DAMAGING
WINDS.

WE WILL CONTINUE TO MONITOR FOR THE SEVERE WEATHER POTENTIAL
TODAY AS THE CLOUD DEBRIS IS THE BIGGEST UNCERTAINTY AT THIS
TIME...WHICH COULD MAKE A HUGE DIFFERENCE IN THE OUTCOME OF THE
DAY.

&&

.SHORT TERM /6 PM THIS EVENING THROUGH 6 AM WEDNESDAY/...
TONIGHT...

ANY ONGOING CONVECTION WILL BE MAINLY OVER THE CAPE/ISLANDS AND
PUSHING OFFSHORE EARLY THIS EVENING. COLD FRONT WILL SWEEP ACROSS
THE REGION SWITCHING THE WINDS TO A WESTERLY DIRECTION. CLOUD
COVER WILL CLEAR OUT ALLOWING FOR OVERNIGHT LOWS TO DROP INTO THE
LOW 60S WITH UPPER 60S IN THE METRO REGIONS. LOW PROBABILITY OF
RADIATIONAL FOG OVERNIGHT THANKS TO RAINFALL FROM THE AFTERNOON
THUNDERSTORMS PROVIDING A MOIST GROUND AS TEMPS COOL OFF. BEST
SHOT WOULD BE IN VALLEYS AND LOW-LYING AREAS.

&&

.LONG TERM /WEDNESDAY THROUGH MONDAY/...
UPDATED 330 AM

HIGHLIGHTS...

* MAJOR PATTERN CHANGE WITH COOLER AND POSSIBLY UNSETTLED WEATHER
* DRY AND SEASONABLE WEDNESDAY-THURSDAY
* UNSEASONABLY COOL WITH PERIODS OF RAIN POSSIBLE LATE THIS WEEKEND

SYNOPTIC OVERVIEW AND MODEL PREFERENCES...

GOOD MODEL AGREEMENT AMONG ENSEMBLES AND DETERMINISTIC GUIDANCE THAT
CLOSED LOW FORMS OVER SOUTHEAST QUEBEC WED AND THEN INTO THE
MARITIMES THU. THIS SHIFTS THE NORTHERN STREAM JET SOUTH AND WEST OF
NEW ENGLAND...SUPPRESSING SUMMER HEAT AND HUMIDITY FROM ENTERING NEW
ENGLAND. THUS DRY AND SEASONABLE WEATHER HERE ALONG WITH LOWER
HUMIDITY WED AND THU. NORTHERN STREAM ENERGY THEN DIVES INTO THE
BASE OF LONG WAVE TROUGH OVER THE NORTHEAST AND MAY YIELD A PERIOD
OF SHOWERS THU NGT INTO EARLY FRI WITH HIGHEST PROBABILITY ACROSS
CT/RI AND SOUTHEAST MA...ESPECIALLY SOUTH COAST.

BY LATER FRIDAY AND INTO SAT DRY WEATHER RETURNS BEHIND DEPARTING
WAVE BUT LIKELY SHORT LIVED AS LARGE AMPLITUDE RIDGE DEVELOPS OVER
THE PACIFIC NORTHWEST INTO WESTERN CANADA...WHICH INDUCES DOWNSTREAM
TROUGHING OVER THE OH AND TN VALLEYS. THIS IS THE BEGINNING OF A
MAJOR PATTERN CHANGE FOR THE CONUS. AT THE SURFACE THIS SUPPORTS LOW
PRES OVER THE MID ATLC REGION AND LIFTING NORTHEAST TOWARD NEW
ENGLAND LATE THIS WEEKEND. THIS WOULD YIELD A PERIOD OF RAINY AND
CHILLY WEATHER FOR SOUTHERN NEW ENGLAND. GIVEN THE TIME RANGE HERE
SURPRISINGLY THE DETERMINISTIC GUIDANCE IS VERY CLOSE. THUS WILL NOT
DEVIATE MUCH FROM A MODEL BLEND APPROACH THIS FORECAST TIME PERIOD.

&&

.AVIATION /14Z TUESDAY THROUGH SATURDAY/...
FORECASTER CONFIDENCE LEVELS...

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

SHORT TERM /THROUGH TUESDAY/...

12Z UPDATE...NO MAJOR CHANGES TO 06Z AND 09Z TAF ISSUANCES.

================================================================

BEFORE 16Z...HIGH CONFIDENCE. VFR...EXPECT PATCHY FOG TO DEVELOP
IN THE TYPICALLY PRONE LOCATIONS...AND IMPROVING BY 12Z. IN
ADDITION...A FEW SHOWERS/ISOLATED THUNDERSTORM OR TWO POSSIBLE
TOWARD DAYBREAK MAINLY NORTH OF THE MASS PIKE.

AFTER 16Z...MODERATE TO HIGH CONFIDENCE. WHILE VFR CONDITIONS
WILL DOMINATE AND MOST SITES SHOULD BE MAINLY DRY THROUGHOUT THE
DAY. EXPECT SCATTERED STRONG TO SEVERE THUNDERSTORMS TO DEVELOP
FROM MID AFTERNOON ACROSS THE INTERIOR AND POSSIBLY REACHING THE
COAST BY LATE AFTERNOON/EARLY EVENING. THESE MAY RESULT IN BRIEF
IFR TO LIFR CONDITIONS WITH VERY STRONG WIND GUSTS AND HAIL.

TONIGHT...CONDITIONS WILL IMPROVE FROM WEST TO EAST. COULD SEE
IFR CONDITIONS ACROSS THE CAPE AND ISLANDS BEFORE COLD FRONT
SWEEPS THROUGH. OTHERWISE WINDS WILL SWITCH TO THE WEST.

KBOS TERMINAL...HIGH CONFIDENCE IN MAINLY VFR CONDITIONS. LOWER
CONFIDENCE ON EXACT TIMING OF THUNDERSTORMS.

KBDL TERMINAL...HIGH CONFIDENCE IN MAINLY VFR CONDITIONS. LOWER
CONFIDENCE ON EXACT TIMING OF THUNDERSTORMS.

OUTLOOK...WEDNESDAY THROUGH SATURDAY...

WEDNESDAY INTO THURSDAY...HIGH CONFIDENCE FOR VFR AND DRY WEATHER.
LOWER CONFIDENCE THU NIGHT AS LOW RISK OF SHOWERS AND MVFR ACROSS
CT/RI AND SOUTHEAST MA.

FRIDAY...MODERATE CONFIDENCE FOR VFR AND DRY WEATHER. JUST A LOW
RISK OF SHOWERS FRI MORNING ACROSS CT/RI AND SOUTHEAST MA.

SATURDAY...MODERATE CONFIDENCE FOR DRY WEATHER AND VFR. HOWEVER RAIN
AND MVFR LIKELY JUST LURKING OFF THE SOUTH COAST.

.MARINE...
FORECASTER CONFIDENCE LEVELS...

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

SHORT TERM /THROUGH TUESDAY NIGHT/...HIGH CONFIDENCE.

TODAY...DEVELOPING LOW LEVEL JET WILL RESULT IN NEAR SHORE SMALL
CRAFT SOUTHWEST WIND GUSTS OF 30 KNOTS. MAY EVEN SEE A FEW BRIEF
GUSTS NEAR 35 KNOTS LATE IN THE AFTERNOON...BUT NOT WIDESPREAD
ENOUGH TO HOIST A GALE WARNINGS. SEAS WILL ALSO BUILD TO BETWEEN 3
AND 6 FEET ACROSS THE OUTER WATERS.

A FEW STRONG TO SEVERE THUNDERSTORMS WITH WIND GUSTS TO 50 KNOTS AND
LARGE HAIL ARE A POSSIBILITY...MAINLY LATE TUESDAY AFTERNOON AND
EARLY EVENING.  WHILE A SEVERE STORM OR TWO CAN NOT BE RULED OUT
ACROSS ANY OF OUR NEARSHORE WATERS...HIGHEST RISK WOULD BE IN THE
WATERS ALONG THE NORTHEAST MA COAST.

TONIGHT...COLD FRONT WILL MOVE ACROSS THE WATERS FROM NW TO SE
TONIGHT SWITCHING THE WINDS TO A MORE WESTERLY DIRECTION. COULD
SEE LINGERING 5 FT SEAS ON THE SOUTHERN OUTER WATERS...SCA WILL
CONTINUE.

OUTLOOK...WEDNESDAY THROUGH SATURDAY...

UPDATED 330 AM...

WEDNESDAY INTO THURSDAY...HIGH CONFIDENCE FOR TRANQUIL BOATING
WEATHER WITH MODEST WEST WINDS. LOW RISK FOR A FEW SHOWERS THU NIGHT
ACROSS THE SOUTHERN WATERS.

FRIDAY AND SATURDAY...MODERATE CONFIDENCE FOR QUIET WEATHER LATER
FRI INTO SAT. HOWEVER LATER SAT NEED TO WATCH LOW PRES ORGANIZING
OVER THE MID ATLC REGION AND POSSIBLY TRACKING NE TOWARD SOUTHERN
NEW ENGLAND LATE SAT.
