AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE TAUNTON MA
445 PM EDT MON JUL 7 2014

.SYNOPSIS...
VERY WARM/HOT AND HUMID WEATHER WILL PERSIST THROUGH MID WEEK.
WHILE MUCH OF THE TIME WILL BE DRY...A FEW STRONG HIT AND MISS
THUNDERSTORMS WILL BE POSSIBLE AT TIMES ESPECIALLY ACROSS THE
INTERIOR. A FEW ADDITIONAL SHOWERS AND THUNDERSTORMS WILL BE
POSSIBLE DURING THURSDAY IF THE COLD FRONT MOVES SLOWER. DRY
WEATHER WITH LOWER HUMIDITY WILL ARRIVE BY THE END OF THE WEEK
INTO THE WEEKEND.

&&

.NEAR TERM /UNTIL 6 AM TUESDAY MORNING/...
***SCATTERED STRONG TO SEVERE THUNDERSTORMS THIS EVENING ACROSS
  PORTIONS OF INTERIOR SOUTHERN NEW ENGLAND***

SHORTWAVE COMBINING WITH MODEST INSTABILITY ALONG WITH 30 TO 40
KNOTS OF SHEAR HAS ALLOWED SCATTERED STRONG TO SEVERE THUNDERSTORMS
TO WORK INTO SOUTHWEST NH/NORTHWEST LATE THIS AFTERNOON.  GIVEN
CAPES ON THE ORDER OF 1000 TO 1500 J/KG INTO THIS EVENING...FEEL THE
THREAT FOR SCATTERED STRONG TO SEVERE THUNDERSTORMS MAY EXPAND TO
AFFECT PORTIONS OF NORTHERN CT...WESTERN/NORTH CENTRAL MA AND INTO
SOUTHERN NH INTO THE EVENING HOURS.  THE PRIMARY THREAT WILL BE
STRONG TO DAMAGING STRAIGHT LINE WIND GUSTS ALONG WITH TORRENTIAL
RAINFALL.  HAIL WILL BE A SECONDARY CONCERN IF ANY DISCRETE CORES
CAN DEVELOP.

THERE IS UNCERTAINTY IF THIS ACTIVITY WILL HOLD TOGETHER AS IT TRIES
TO ENTER EASTERN MA/RHODE ISLAND.  WE SHOULD SEE A WEAKENING
TREND...BUT STILL AT LEAST SOME CONVECTIVE POTENTIAL GIVEN 30+ KNOTS
OF SHEAR ALONG WITH SOME INSTABILITY.  WILL HAVE TO MONITOR THIS
CLOSELY THIS EVENING.

SHOULD SEE THE ACTIVITY WIND DOWN NEAR OR SHORTLY AFTER MIDNIGHT AS
THE SHORTWAVE DEPARTS.  OTHERWISE...CAN/T RULE OUT A SPOT SHOWER OR
THUNDERSTORM GIVEN LOW LEVEL JET AND LEFT OVER INSTABILITY...BUT THE
VAST MAJORITY OF THE NIGHT SHOULD BE DRY.  LOW TEMPS WILL ONLY FALL
BACK TO THE LOWER 70S IN MOST LOCALES...WITH PERHAPS A FEW UPPER 60S
IN NORTHWEST MA/SOUTHWEST NH.

&&

.SHORT TERM /6 AM TUESDAY MORNING THROUGH TUESDAY NIGHT/...
TUESDAY AND TUESDAY NIGHT...

ANOTHER VERY WARM/HOT AND HUMID DAY ACROSS THE REGION.  HIGHS SHOULD
TOP OUT AROUND 90 TO THE LOWER 90S IN MANY LOCATIONS...ALTHOUGH A
FEW DEGREES COOLER ON THE SOUTH COAST/CAPE ISLANDS WITH SOUTHWEST
WINDS.  IT WILL ONCE AGAIN BE BREEZY IN THE AFTERNOON WITH SOUTHWEST
WIND GUSTS OF 20 TO 30 MPH.

WHILE MUCH OF THE DAY WILL BE DRY...THE ATMOSPHERE WILL BECOME
MODERATELY UNSTABLE DURING THE AFTERNOON.  EXPECT 1000 TO 2000 J/KG
OF CAPE TO DEVELOP ALONG WITH 30 TO 40 KNOTS OF SHEAR.  THE MAIN
UNCERTAINTY IS THAT WE DON/T HAVE AS STRONG A SHORTWAVE APPROACHING
AS THE ONE THIS AFTERNOON/EVENING.  HOWEVER...GIVEN VERY GOOD
INSTABILITY/SHEAR WE PROBABLY WILL SEE ISOLATED TO SCATTERED
THUNDERSTORMS DEVELOP DURING THE LATE AFTERNOON/EVENING HOURS.
WHILE AREAL COVERAGE REMAINS UNCERTAIN AND COULD BE LIMITED...ANY
STORM OR STORM/S THAT ARE ABLE TO DEVELOP IN THIS ENVIRONMENT COULD
BECOME STRONG TO SEVERE.  THE MAIN THREAT WOULD BE STRONG TO
DAMAGING STRAIGHT LINE WIND GUSTS...BUT LARGE HAIL CAN/T BE RULED
OUT WITH ANY DISCRETE CELLS.  HEAVY RAINFALL AND DANGEROUS CLOUD TO
GROUND LIGHTNING WILL BE THE MAIN THREATS WITH THIS ACTIVITY.

BEST SHOT FOR A FEW STRONG TO SEVERE THUNDERSTORMS WILL BE NORTHWEST
OF A BOSTON TO PROVIDENCE LINE...ALTHOUGH CAN/T REALLY RULE ONE OUT
ANYWHERE.  SHOULD SEE ACTIVITY WIND DOWN AFTER MIDNIGHT...BUT CAN/T
RULE OUT A FEW SPOT SHOWERS/THUNDERSTORMS RIGHT THROUGH DAYBREAK
WEDNESDAY GIVEN GOOD JET DYNAMICS/INSTABILITY.

&&

.LONG TERM /WEDNESDAY THROUGH MONDAY/...
HIGHLIGHTS...

* VERY WARM/HOT AND HUMID ON WED
* A FEW THUNDERSTORMS POSSIBLE WED INTO THU
* DRIER AND LESS HUMID AIR RETURNS BY THE END OF THE WEEK

OVERVIEW AND MODEL PREFERENCES...
MEDIUM RANGE MODEL SUITE ARE IN GOOD AGREEMENT IN CONTINUING TO
DIG A LONG WAVE UPPER TROUGH/CUTOFF LOW FROM HUDSON BAY THROUGH
THE GREAT LAKES TO THE OHIO VALLEY WHILE RIDGING BUILDS ACROSS
WESTERN CANADA INTO THE NORTHERN ROCKIES INTO THURSDAY. WITH THE
TROUGH AXIS CUTTING THROUGH THE LAKES...WILL SEE SLOW PROGRESSION
OF COLD FRONT TRYING TO SLICE THROUGH THE REGION. ONCE THIS TROUGH
LIFTS NE LATER THU/THU NIGHT...CONDITIONS LOOK TO IMPROVE WITH
DRIER AIR MOVING IN. TIMING OF NEXT SYSTEM WORKING ACROSS THE
NORTHERN TIER STATES IS IN QUESTION WITH LACK OF MODEL
CONTINUITY...THOUGH LOOKS LIKE ANOTHER H5 CUTOFF LOW DIGS OUT OF
NORTHERN CANADA ACROSS HUDSON BAY INTO EARLY NEXT WEEK...SO
ANOTHER TROUGH MAY START TO DIG SERD. MODELS ARE DIVIDED ON HOW
FAR THIS WILL DIG S AND HOW SURFACE SYSTEMS RIDING ALONG IN THIS
FLOW WILL MOVE...SO LOWER CONFIDENCE IN FORECAST BEYOND SATURDAY.

WITH THE GOOD AGREEMENT WITH THE MODELS EARLY IN THIS
CYCLE...USED A BLEND OF AVAILABLE GUIDANCE THEN LEANED TOWARD THE
ENSEMBLES BEYOND FRIDAY WITH THE TIMING ISSUES NOTED.

DETAILS...

WEDNESDAY/WEDNESDAY NIGHT...
WITH THE COLD FRONT RUNNING NEARLY PARALLEL TO THE UPPER LEVEL
TROUGH...WILL BE SLOW TO EXIT THE REGION. STILL QUITE A BIT OF
INSTABILITY ACROSS THE REGION WITH CAPES IN THE 500-1000 J/KG
RANGE AND LIFTED INDICES BELOW ZERO. SO...KEPT CHANCE OF
SHOWERS/TSTMS GOING IN THE FORECAST. ALSO...PWATS ARE 1.8 TO 1.9
INCHES...SO WILL SEE HEAVY RAINERS WITH ANY TSTMS. KEPT HEAVY
RAINFALL WORDING GOING IN THE FORECAST INTO EARLY WED NIGHT. WILL
ALSO NEED TO MONITOR WIND SHEAR ON ORDER OF AROUND 40 KT WHICH
COULD HELP VENT ANY CONVECTION ALONG WITH THE CAPES AND LI/S.
EXPECTING WARM AND HUMID CONDITIONS WITH HIGHS IN THE
80S...HIGHEST ACROSS E MA/RI/N CT.

FOR NOW...LOOKS LIKE THE FRONT WILL CLEAR THE COAST OVERNIGHT WED
BUT MAY HUG THE COAST INTO THU MORNING. BRINGING BACK EDGE OF
PRECIP SLOWLY SEWD AND HAVE KEPT MENTION OF THUNDER IN GENERALLY
ACROSS AREAS S OF THE MASS PIKE.

THURSDAY...
HAVE KEPT SLIGHT CHANCE MENTION OF SHOWERS/TSTMS...MAINLY ACROSS
E MA/RI/NE CT THU MORNING...THEN SHOULD SHIFT OFFSHORE DURING THE
AFTERNOON. THIS WILL BE DEPENDENT UPON TIMING OF THE UPPER TROUGH
TO THE N AND W. MODELS DO SHOW PRETTY GOOD AGREEMENT THOUGH. WILL
STILL NEED TO MONITOR THE TIMING AND WHETHER MORE INSTABILITY THAN
CURRENTLY INDICATED WILL HANG BACK. DEWPTS IN THE LOWER-MID 60S DO
HANG BACK ACROSS THE AREA...SO MAY HAVE SOME PROBLEMS EARLY.

FRIDAY AND SATURDAY...
HIGH PRES WILL PUSH E FROM THE GREAT LAKES...BRINGING COOLER AND
DRIER CONDITIONS. SEA BREEZES WILL BE LIKELY BOTH DAYS WITH THE
LIGHT WIND FLOW IN PLACE THANKS TO THE HIGH. DAYTIME HIGHS WILL BE
IN THE LOWER 80S...CLOSE TO SEASONAL NORMALS. CLOUDS LOOK TO
INCREASE FROM THE W SATURDAY NIGHT.

SUNDAY AND MONDAY...
AS LONG WAVE TROUGHING LOOKS TO RETURN TO THE W OF THE REGION...
MAY SEE ANOTHER FRONT BEGIN TO APPROACH. HOWEVER...DUE TO TIMING
ISSUES...NOT A LOT OF CONFIDENCE BUT DOES LOOK LIKE ANOTHER ROUND
OF SCT SHOWERS/TSTMS RETURN.

&&

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

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

SHORT TERM /THROUGH TUESDAY NIGHT/...

THIS AFTERNOON AND TONIGHT...MODERATE CONFIDENCE.  SCT
SHOWERS/THUNDERSTORMS ARE EXPECTED TO MOVE INTO INTERIOR SOUTHERN
NEW ENGLAND ROUGHLY BETWEEN 4 PM AND MIDNIGHT.  A FEW OF THE
STORMS MAY RESULT IN STRONG WIND GUSTS AND BRIEF TORRENTIAL RAIN.
THE ACTIVITY WILL BE HIT AND MISS...BUT WILL RESULT IN LOCALIZED
MVFR-IFR CONDITIONS.  ACTIVITY SHOULD WEAKEN AS IT MOVES INTO
EASTERN MA/RI...BUT A FEW THUNDERSTORMS CAN/T BE RULED OUT AFTER 8
OR 9 PM THROUGH ABOUT MIDNIGHT.  SOUTHWEST WIND GUSTS OF 25 TO 30
KNOTS SHOULD DIMINISH SOME AFTER SUNSET WITH THE LOSS OF DAYTIME
HEATING.

OTHERWISE...VFR CONDITIONS DOMINATE THROUGH TONIGHT OTHER
THAN SOME LOCALIZED PATCHY GROUND FOG LATE.  LOW PROBABILITY THAT
LOW CLOUDS/FOG DEVELOP ACROSS SOUTHEAST NEW ENGLAND BUT DIDN/T HAVE
ENOUGH CONFIDENCE TO INSERT INTO THE TAF.  LATER SHIFTS WILL HAVE TO
MONITOR.

TUESDAY AND TUESDAY NIGHT...MODERATE CONFIDENCE.  VFR CONDITIONS
WILL DOMINATE...BUT PERHAPS A BETTER CHANCE OF LOW CLOUDS AND FOG
DEVELOPING ALONG THE SOUTHEAST NEW ENGLAND COAST TUE NIGHT.  IN
ADDITION...A FEW AFTERNOON AND EVENING STRONG THUNDERSTORMS ARE
POSSIBLE WITH THE BEST SHOT NORTHWEST OF A BOS TO PVD LINE.

KBOS TAF...MODERATE CONFIDENCE IN TAF.  LOW PROBABILITY FOR A
THUNDERSTORM IN THE VICINITY BETWEEN 00Z AND 04Z.

KBDL TAF...MODERATE CONFIDENCE IN TAF.  LOW TO MODERATE PROBABILITY
FOR A FEW STRONG THUNDERSTORMS IN THE VICINITY BETWEEN 21Z AND 03Z.

OUTLOOK...WEDNESDAY THROUGH SATURDAY...

WEDNESDAY...MODERATE CONFIDENCE. MAINLY VFR AWAY FROM THE COAST.
AREAS OF IFR CIGS/VSBYS ACROSS COASTAL AREAS IN LOW CLOUDS/FOG
WHICH SHOULD IMPROVE BY AROUND MID MORNING...BUT WILL REDEVELOP
AFTER MIDNIGHT WED NIGHT. WILL SEE LOCAL BRIEF MVFR-IFR CIGS/VSBYS
IN SCT SHOWERS/TSTMS.

THURSDAY...MODERATE CONFIDENCE. SHOULD BE MAINLY VFR. WIDELY SCT
SHOWERS LINGER WITH LOCAL MVFR VSBYS. ISOLD THUNDER POSSIBLE ALONG
S COAST.

FRIDAY...HIGH CONFIDENCE. VFR CONDITIONS.

SATURDAY...MODERATE CONFIDENCE. VFR INTO EARLY SATURDAY NIGHT.
MAY SEE MVFR CIGS/VSBYS AFTER MIDNIGHT IN SCT SHOWERS/ISOLD TSTMS
ACROSS WESTERN AREAS AS ANOTHER SYSTEM APPROACHES. LOWER
CONFIDENCE DUE TO TIMING ISSUES.

&&

.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.

PERSISTENT SOUTHWEST FLOW WILL CONTINUE RIGHT THROUGH TUESDAY NIGHT
AHEAD OF A SLOW MOVING COLD FRONT.  NEAR SHORE GUSTS OF 25 TO 30
KNOTS WILL DIMINISH AFTER SUNSET...SO WILL BE ABLE TO LET SOME OF
THE NEAR SHORE HEADLINES EXPIRE.  WINDS MAY BE A TOUCH LESS GUSTY ON
TUESDAY...BUT STILL THE RISK FOR 25 KNOT WIND GUSTS SO MORE NEAR
SHORE SCA HEADLINES MAY BE NEEDED.  AS FOR THE OUTER-WATERS...WILL
CONTINUE TO NEED SCA HEADLINES WITH LONG SOUTHWEST FETCH RESULTING
IN 4 TO 7 FOOT SEAS.

OTHERWISE...MAY SEE AREAS OF FOG DEVELOP MAINLY TUE NIGHT WHICH
COULD BE LOCALLY DENSE ACROSS THE SOUTHERN WATERS. IN ADDITION...LOW
TO MODERATE PROBABILITY FOR A FEW STRONG THUNDERSTORMS TO MOVE
ACROSS THE NEAR SHORE WATERS THIS EVENING AND AGAIN LATE TUE.

OUTLOOK...WEDNESDAY THROUGH SATURDAY.

WEDNESDAY...MODERATE CONFIDENCE. S-SW WINDS CONTINUE AT 10-15 KT.
A FEW GUSTS TO 20 KT POSSIBLE THROUGH THE DAYLIGHT HOURS. S SWELLS
WILL CONTINUE AT 5-7 FT ON THE OUTER WATERS. REDUCED VSBYS IN FOG
WILL CONTINUE. SCT SHOWERS/TSTMS WITH HEAVY RAINFALL THROUGH WED
EVENING.

THURSDAY...MODERATE CONFIDENCE. S-SW WINDS BELOW 15 KT DURING THE
DAY WILL SLOWLY SHIFT TO W-NW THURSDAY NIGHT. MAY SEE 5 FOOT SEAS
ACROSS THE SOUTHERN OUTER WATERS EARLY...THEN SHOULD SUBSIDE.

FRIDAY-SATURDAY...HIGH CONFIDENCE.
WINDS AND SEAS BELOW SMALL CRAFT CRITERIA.
