AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE TAUNTON MA
440 PM EDT TUE AUG 18 2015

.SYNOPSIS...
SCATTERED SHOWERS AND THUNDERSTORMS END EARLY THIS EVENING. WITH A
BROAD AREA OF HIGH PRESSURE OFFSHORE...LIGHT SOUTH WINDS OVER OUR
AREA WILL ENSURE THAT MUGGY CONDITIONS PERSIST ACROSS THE AREA
DURING THIS WEEK. ISOLATED SHOWERS ARE POSSIBLE ACROSS THE FAR
INTERIOR DURING WEDNESDAY AND THURSDAY. THEN UNSETTLED WEATHER IS
EXPECTED AHEAD OF AN APPROACHING COLD FRONT WHICH MAY STALL ACROSS
THE REGION OVER THIS WEEKEND.

&&

.NEAR TERM /UNTIL 6 AM WEDNESDAY MORNING/...
4 PM UPDATE...RADAR SHOWS ISOLATED TO SCATTERED SHOWERS/T-STORMS
CONTINUE...WITH MAIN FOCUS IN THE BOSTON AREA FROM INTERACTION OF
SHOWERS/T-STORMS AND ASSOCIATED OUTFLOW BOUNDARIES WITH THE SEA
BREEZE FRONT. THE SHOWERS/THUNDERSTORMS ARE EXPECTED TO COME TO AN
END DURING EARLY THIS EVENING...WITH THE LOSS OF DAYTIME HEATING
AND LIMITED SYNOPTIC FORCING.

FORECAST PROBLEM FOR TONIGHT WILL BE HOW MUCH LOW CLOUDS AND FOG
FORM. SOME MODEL GUIDANCE IS INDICATING LOW CLOUDS WILL OVERSPREAD MUCH
OF SNE OVERNIGHT. AREAL COVERAGE AND EXTENT OF THE LOW CLOUDS AND
FOG ARE STILL NOT A CERTAINTY...BUT LOW CLOUD DEVELOPMENT LOOKS
LIKELY SO WILL CONTINUE FORECAST WITH A GRADUAL INCREASE IN CLOUDS
OVERNIGHT...WITH THE MOST CLOUD COVER OVER SOUTH COASTAL AREA. LOW
TEMPS WILL BE IN THE UPPER 60S TO LOWER 70S AND IT AGAIN WILL BE
MUGGY.

&&

.SHORT TERM /6 AM WEDNESDAY MORNING THROUGH WEDNESDAY NIGHT/...
WEDNESDAY...

WHILE THERE IS STILL SOME UNCERTAINTY ON THE EXTENT OF LOW CLOUDS
AND FOG FORMING TONIGHT...BUT DURING WEDNESDAY MORNING ANY LOW
CLOUD/FOG WILL GRADUALLY LIFT/DISSIPATE DURING THE MORNING.
ANTICIPATING MOSTLY SUNNY SKIES FOR THE AFTERNOON. MODELS SHOW
WEAK RIDGING ALOFT DURING THE DAY...AND BUFKIT MODEL SOUNDINGS
SHOWING THE AIR COLUMN BEING WARM ENOUGH ALOFT TO HINDER MOST
CONVECTION. MOISTURE IS MORE LIMITED AS WELL...WITH PWATS ONLY
AROUND AN INCH. A SPOT SHOWER OR TWO IS POSSIBLE IN THE WESTERN
ZONES...INFLUENCED BY THE TERRAIN...SO WILL CONTINUE SLIGHT
CHANCE POPS OUT THERE. A FEW SPOTS MAY HIT 90 DEGREES AGAIN...BUT
FOR MOST OF THE AREA HIGHS IN THE MID AND UPPER 80S ARE EXPECTED.
CONTINUED QUITE MUGGY WITH DEWPOINTS IN THE MID 60S TO LOW 70S.

WEDNESDAY NIGHT...

WHILE MAINLY DRY CONDITIONS ARE EXPECTED...THE POTENTIAL EXISTS
FOR AREAS OF LOW CLOUDS AND FOG TO FORM ONCE AGAIN.

&&

.LONG TERM /THURSDAY THROUGH TUESDAY/...
HIGHLIGHTS...
* WARM AND MUGGY CONDITIONS PERSIST THROUGHOUT THIS WEEK
* SHOWERS AND THUNDERSTORMS POSSIBLE WITH WEAK FRONT THU AND FRI
* UNSETTLED WEATHER CONTINUES AS THIS FRONT STALLS NEAR OUR REGION

18/12Z MODELS REMAIN IN GOOD AGREEMENT THROUGH THIS PORTION OF THE
FORECAST. AN UPPER LEVEL RIDGE JUST OFFSHORE KEEPS SOUTHERN NEW
ENGLAND IN WARM...MUGGY...SOUTHWESTERLY FLOW. A WEAK COLD FRONT
WILL MOVE TOWARD SOUTHERN NEW ENGLAND FRIDAY...BEFORE STALLING
SOMEWHERE NEAR OUR REGION AND PROVIDING A FORCING MECHANISM FOR
SHOWERS AND THUNDERSTORMS THROUGH THIS WEEKEND. THE BIG QUESTION
IS WHERE EXACTLY DOES IT STALL.

THURSDAY...SHOWERS ARE POSSIBLE ACROSS THE NORTHWESTERN PORTIONS
OF SOUTHERN NEW ENGLAND. TEMPERATURES DROP A FEW DEGREES...BUT
HUMID CONDITIONS CONTINUE.

FRIDAY THROUGH SUNDAY...A WEAK COLD FRONT MOVES INTO SOUTHERN NEW
ENGLAND FRIDAY...STALLING ACROSS SOMEWHERE IN OUR AREA THROUGH
THIS WEEKEND. THIS WILL BE THE FOCUS FOR SHOWERS AND THUNDERSTORMS
WITH THE MAIN THREATS BEING HEAVY RAIN AND LIGHTNING. WITH
PRECIPITABLE WATER VALUES RUNNING NEAR OR ABOVE 2 INCHES DURING
THIS TIME...URBAN AND POOR DRAINAGE FLOODING REMAINS A STRONG
POSSIBILITY. HOWEVER...WEAK WINDS THROUGH THE COLUMN AND POOR MID
LEVEL LAPSE RATES INDICATE THAT SEVERE WINDS OR HAIL ARE UNLIKELY.

MONDAY AND TUESDAY...LATEST INDICATIONS ARE THAT THE STALLED FRONT
FINALLY DISSIPATES. WILL HAVE TO KEEP AT LEAST A CHANCE OF SHOWERS
AND THUNDERSTORMS IN THE FORECAST THOUGH...AS ANOTHER COLD FRONT
SHOULD APPROACH FROM THE WEST DURING THIS TIME.

&&

.AVIATION /20Z TUESDAY THROUGH SUNDAY/...
FORECASTER CONFIDENCE LEVELS...

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

SHORT TERM /TODAY THROUGH WEDNESDAY/...

LATE THIS AFTERNOON...MODERATE TO HIGH CONFIDENCE. MAINLY VFR
CONDITIONS BUT SCATTERED SHOWERS/THUNDERSTORMS THIS AFTERNOON WILL
RESULT IN LOCALIZED LOWER CIGS/VSBYS. ACTIVITY WILL BE HIT AND
MISS...SO MANY LOCATIONS MAY REMAIN DRY. THE TERMINAL MOST
AFFECTED IS BOS/LOGAN...DUE IN LARGE PART TO THE PRESENCE OF THE
SEA BREEZE FRONT.

TONIGHT...MODERATE CONFIDENCE.  ANY LEFT OVER SCATTERED
SHOWERS/THUNDERSTORMS SHOULD DISSIPATE THIS EVENING. OTHERWISE...
IFR/LIFR LOW CLOUDS AND FOG PATCHES SHOULD DEVELOP ACROSS THE
SOUTH COAST/CAPE AND ISLANDS THIS EVENING. THESE LOW CLOUDS/FOG
PATCHES SHOULD ADVANCE FURTHER NORTH AND WEST...PROBABLY PRODUCING
MVFR/IFR CIGS/VSBYS LATE TONIGHT FOR MUCH OF THE REGION. HOWEVER
THERE IS UNCERTAINTY ON AREAL COVERAGE AND TIMING.

WEDNESDAY...MODERATE CONFIDENCE. LOW CLOUDS AND FOG PATCHES
EXPECTED TO LIFT AND DISSIPATE DURING MID MORNING. VFR CONDITIONS
EXPECTED THEREAFTER.

WEDNESDAY NIGHT...MODERATE CONFIDENCE.  POTENTIAL FOR RENEWED
MVFR/IFR CIGS/VSBYS IN AREAS OF FOG AS NIGHT PROGRESSES.

KBOS TERMINAL...MODERATE CONFIDENCE IN TAF. GREATEST UNCERTAINTY
IN CIG/VSBY AT BOS EXISTS THRU 22Z DUE TO PRESENCE OF
SHOWERS/T-STORMS INTERACTING WITH THE LOCAL SEA BREEZE BOUNDARY.
MAIN THREAT FOR T- STORMS IS EXPECTED THRU 22Z. THEREAFTER
CONDITIONS SHOULD IMPROVE TO VFR FOR MUCH OF THE NIGHT. LOW
CLOUDS/FOG MAY ADVANCE TO BOS LATER TONIGHT...WITH IMPROVEMENT TO
VFR DURING WED MORNING.

KBDL TERMINAL...MODERATE CONFIDENCE IN TAF. RISK FOR SHOWERS/T-
STORMS NEAR BDL THRU 22Z...THEN CONDITIONS SHOULD IMPROVE TO VFR
FOR THE EVENING. LOW CLOUDS AND FOG MAY MOVE INTO THE TERMINAL
LATER TONIGHT...BUT CONFIDENCE ON EXACT TIMING IS LOW. IMPROVING
BACK TO VFR WED MORNING.

OUTLOOK /THURSDAY THROUGH SUNDAY/...

THURSDAY...MODERATE CONFIDENCE. MAINLY VFR DURING THE DAY.
MVFR/IFR CONDITIONS IN PATCHY FOG AT NIGHT. LOW PROBABILITY OF
MVFR/IFR CONDITIONS IN SCT SHRA/TSRA WEST OF KORH.

FRIDAY THROUGH SUNDAY...MODERATE CONFIDENCE. MAINLY VFR. SCT
SHRA/TSRA EXPECTED WITH A COLD FRONT. MVFR/IFR CONDITIONS POSSIBLE
IN +RA.

&&

.MARINE...
FORECASTER CONFIDENCE LEVELS...

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

HIGH CONFIDENCE. WEAK PRESSURE GRADIENT WILL KEEP WINDS/SEAS BELOW
SMALL CRAFT ADVISORY THRESHOLDS THROUGH WEDNESDAY NIGHT. SOME
SHOWERS/THUNDERSTORMS ARE ALSO POSSIBLE ACROSS THE NEAR SHORE
WATERS INTO EARLY THIS EVENING /ESPECIALLY NEAR THE BOSTON AREA/.
LASTLY...AREAS OF FOG ARE EXPECTED TO DEVELOP TONIGHT AND PERSIST
INTO AT LEAST EARLY WEDNESDAY MORNING ACROSS THE SOUTHERN WATERS.
AREAS OF FOG MAY DEVELOP AGAIN WEDNESDAY NIGHT.

OUTLOOK /THURSDAY THROUGH SUNDAY/...

HIGH CONFIDENCE. MAINLY QUIET BOATING WEATHER UNDER A STRONG UPPER
LEVEL RIDGE. SHOWERS AND THUNDERSTORMS ARE POSSIBLE OVER THE
WATERS AT TIMES FRIDAY INTO SUNDAY...RESULTING IN LIGHTNING...
GUSTY WINDS...AND LIMITED VISIBILITIES IN HEAVY RAIN.
