AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE TAUNTON MA
156 PM EDT THU AUG 6 2015

.SYNOPSIS...
HIGH PRESSURE WILL REMAIN IN PLACE THROUGH FRIDAY. LOW PRESSURE
PASSING SOUTH OF NEW ENGLAND MAY BRING A PERIOD OF UNSETTLED
CONDITIONS TO PORTIONS OF THE COAST FRIDAY NIGHT INTO THIS
WEEKEND...THOUGH TIMING AND TRACK ARE UNCERTAIN. ANOTHER BRIEF
PERIOD OF DRY AND MILD WEATHER EXPECTED ON MONDAY...FOLLOWED BY A
SLOW MOVING FRONT THAT MAY APPROACH DURING THE TUESDAY-WEDNESDAY
TIMEFRAME.

&&

.NEAR TERM /UNTIL 6 PM THIS EVENING/...

140 PM UPDATE...

FAIR WEATHER CUMULUS CLOUDS HAVE DEVELOPED ACROSS MOST OF THE
REGION AWAY FROM THE COAST. HIGH CLOUD VEIL CONTINUES TO MOVE
ACROSS THE REGION AS WELL...WITH THICKEST CLOUDINESS ACROSS MOST
OF CT AT 17Z. GENERAL W-NW WINDS CONTINUE EXCEPT ALONG IMMEDIATE
S COAST WHERE SEA BREEZES OR GRADIENT W-SW WINDS IN PLACE AT A FEW
LOCATIONS.

TEMPS HAVE RESPONDED NICELY WITH READINGS GENERALLY BETWEEN 75
AND 80. DEWPTS MAINLY IN THE LOWER-MID 50S EXCEPT ACROSS THE
OUTER CAPE AND ISLANDS WHERE THEY ARE AROUND 60.

NEAR TERM FORECAST ON TRACK...BUT HAVE UPDATED NEAR TERM GRIDS TO
BRING CONDITIONS CURRENT.

PREVIOUS DISCUSSION...
LEADING EDGE OF HIGH THIN CLOUDS WORKING NE INTO W CT/MA. WITH
GENERAL W-E WIND FLOW ALOFT...WILL SEE THESE CLOUDS PUSH ACROSS
MOST IF NOT THE ENTIRE REGION DURING THE AFTERNOON. THIS WILL ONLY
FILTER THE BRIGHT SUNSHINE JUST A BIT...THOUGH CLOUDS MAY BECOME
THICKER DURING THE MID TO LATE AFTERNOON ACROSS N CT/RI/SE MA.

NOTING GENERAL W-NW WINDS AT 5-10 KT WHICH WILL INCREASE TO 10-15
KT THIS AFTERNOON WITH GOOD LOW LEVEL MIXING IN PLACE. ONLY
QUESTION IN PLACE WILL BE ALONG THE IMMEDIATE S COAST...OUTER CAPE
COD AND THE ISLANDS WHERE LOWER MIXING VALUES ARE IN PLACE. WINDS
THERE MAY BACK TO W-SW DURING THE AFTERNOON WITH WEAKER PRES
GRADIENT.

&&

.SHORT TERM /6 PM THIS EVENING THROUGH 6 PM FRIDAY/...
OVERNIGHT...
HIGH PRES WILL BE MOVING N OF THE REGION DURING THE OVERNIGHT
HOURS AS THE FIRST IN A SERIES OF MID ATLANTIC LOW PRES WAVES
BEGINS TO MOVE ALONG A STATIONARY FRONT STALLED TO THE S. COLUMN
LOOKS DRY PER BUFKIT DATA...AND WITH HIGH PRES NEARBY...SUSPECT
LITTLE TO NO IMPACT IN TERMS OF PRECIP WITH THIS WAVE PASSAGE.
WILL SEE SOME INCREASING CI...BUT WEAK FLOW SHOULD STILL ALLOW
OVERNIGHT MIN TEMPS TO DROP BACK INTO THE 50S. ANOTHER COMFORTABLE
NIGHT.

FRI...
SAME SLOW MOVING LOW PRES WAVE WILL BE APPROACHING THE 40/70
BENCHMARK /YES THAT WINTER BENCHMARK/. THE SLOW MOVEMENT AND
REASONABLE STRONG BLOCKING RIDGE TO THE N SUGGEST THAT THE HIGH
PRES WILL REMAIN IN CONTROL THROUGH FRI. ASIDE FROM CI POSSIBLY
SOME MID CLOUDS...STILL EXPECTING PRECIP SHIELD TO REMAIN
OFFSHORE.

ONE IMPACT WILL BE SHIFT IN THE WINDS...MAINLY ONSHORE FROM THE E
COAST. SST OFFSHORE ARE IN THE UPPER 60S AND LOW 70S. MAV/MET
TEMPS MAY ACTUALLY A BIT TOO WARM SO BLENDED WITH THE 2M TEMPS TO
BRING THE HIGHS DOWN A BIT. RANGES LOOK TO BE FROM THE LOW 70S
E...TO THE LOW 80S IN HE CT VALLEY.

&&

.LONG TERM /FRIDAY NIGHT THROUGH WEDNESDAY/...
HIGHLIGHTS...

* UNSETTLED WEATHER REMAINS POSSIBLE FRIDAY NIGHT INTO THIS WEEKEND
* TEMPERATURES TRENDING BELOW NORMAL THROUGH MOST...IF NOT ALL...
  OF THIS PERIOD

OVERVIEW AND MODEL PREFERENCES...

GUIDANCE CONTINUES TO SEND MIXED SIGNALS REGARDING THE POTENTIAL
FOR RAINFALL THIS WEEKEND. MANY OF THE INDIVIDUAL MODELS CONTINUE
TO EXHIBIT CONSISTENCY ISSUES...PARTICULARLY THE ECMWF. THE MAIN
PROBLEM IS THE LOCATION OF A HIGH PRESSURE RIDGE EXTENDING SOUTH
FROM EASTERN CANADA...AND A TRACK OF A LOW PRESSURE FROM THE MID
ATLANTIC COAST. GIVEN THE VARIATIONS AMONG THE GUIDANCE...STILL
THINK A CONSENSUS APPROACH IS BEST. LOW CONFIDENCE IN THE DETAILS
INTO EARLY NEXT WEEK.

DETAILS...

FRIDAY NIGHT THROUGH SUNDAY...WITH MID LEVEL TROUGH DIGGING OFF
THE MID ATLANTIC COAST...THE SURFACE LOW MAY START TO BE DRAWN
BACK TOWARD THE COAST. BIG QUESTION IS...HOW CLOSE. HIGH PRESSURE
OVER EASTERN CANADA MAY KEEP THIS LOW PRESSURE FARTHER OUT TO SEA.
IN ANY CASE...THINK IT BEST TO KEEP A CHANCE OF RAINFALL ACROSS
SOUTHEAST MA FRIDAY NIGHT INTO SATURDAY. 06/03Z SREF BRINGS
RAINFALL THE FARTHEST WEST. EVEN RAINFALL AMOUNTS ARE UNCERTAIN...
EXHIBITING A SHARP GRADIENT ACROSS CAPE COD AND THE ISLANDS. KEPT
RAINFALL RATHER LIGHT AT THIS TIME...BUT IT WILL NOT TAKE MUCH OF
A WESTWARD JOG TO SIGNIFICANTLY INCREASE RAINFALL ACROSS THE
OUTER CAPE AND NANTUCKET.

ONE FEATURE THAT IS MORE CERTAIN WILL BE THE ONSHORE WINDS. WILL
LIKELY SEE NE WINDS FRESHEN OVER THIS WEEKEND.

MONDAY THROUGH WEDNESDAY...BIG QUESTION FOR THIS TIMEFRAME WILL BE
THE UPPER LEVEL PATTERN CHANGE THAT TAKES PLACE. WE CONTINUE TO
NOTE LONGWAVE RIDGE BUILDING ACROSS THE PLAINS STATES WITH
RESPONDING DIGGING TROUGH OVER THE APPALACHIANS.

WARM FRONT BEGINS TO APPROACH SOUTHERN NEW ENGLAND MONDAY
AFTERNOON...BRINGING A CHANCE FOR SHOWERS AND A FEW
THUNDERSTORMS. ANOTHER FRONT BEGINS TO APPROACH DURING TUESDAY...
BUT WILL BE SLOW TO MOVE THROUGH DUE TO DIGGING TROUGH IN PLACE.
ANOTHER COASTAL LOW PRESSURE COULD IMPACT OUR REGION TUESDAY NIGHT
INTO WEDNESDAY. LOW CONFIDENCE CONTINUES DUE TO TIMING AND TRACK
ISSUES. WILL KEEP A PROLONGED PERIOD OF CHANCE POPS...FOR NOW.

&&

.AVIATION /18Z THURSDAY THROUGH TUESDAY/...
FORECASTER CONFIDENCE LEVELS...

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

SHORT TERM /THROUGH FRIDAY NIGHT/...

BREEZES MAINLY ALONG IMMEDIATE S COAST.

LIFR ACROSS PARTS OF N CENTRAL-NW MA FROM AROUND 07Z- 12Z IN
PATCHY VALLEY FOG.

FRIDAY AND FRIDAY NIGHT...MODERATE TO HIGH CONFIDENCE...MAINLY FOR
TIMING AND PLACEMENT OF ANY PRECIP INTO CAPE COD/NANTUCKET.
MAINLY VFR. LOW CHANCE FOR -RA/-SHRA INTO CAPE COD/NANTUCKET FRI
AFTERNOON/NIGHT WITH LOCAL MVFR CONDITIONS. MAY SEE PATCHY FOG
AGAIN LATE FRI NIGHT WELL INLAND WITH MVFR-IFR VSBYS.

KBOS TERMINAL...HIGH CONFIDENCE IN TAF.

KBDL TERMINAL...HIGH CONFIDENCE IN TAF.

OUTLOOK /SATURDAY THROUGH MONDAY/...

SUNDAY NIGHT AND MONDAY...LOW CONFIDENCE MAINLY FOR TIMING. MAINLY
VFR. MAY SEE PATCHY LATE NIGHT FOG SUNDAY NIGHT WITH LOCAL MVFR-

SHOWERS/ISOLD TSTMS DEVELOP FROM W-E LATE MON MORNING THROUGH THE

FORECASTER CONFIDENCE LEVELS...

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

SHORT TERM /THROUGH FRIDAY/...

THROUGH 00Z...HIGH CONFIDENCE. HIGH PRES WILL BUILD N AND W OF
THE WATERS. THIS WILL ALLOW WINDS AND SEAS TO REMAIN BELOW SMALL
CRAFT CRITERIA. DRY AND QUIET BOATING WX EXPECTED.

FRIDAY...HIGH CONFIDENCE.
ALTHOUGH LOW PRES WILL BE APPROACHING THE WATERS FROM THE
SW WITH INCREASING SWELLS...HIGH PRES REMAINS IN CONTROL. AT THIS
TIME...EXPECT MAINLY QUIET BOATING WX. ALTHOUGH SOME SHOWERS MAY
SKIRT THE SRN WATERS AT TIMES BY LATE DAY FRI.

OUTLOOK /FRIDAY NIGHT THROUGH MONDAY/...

FRIDAY NIGHT THROUGH SUNDAY...MODERATE CONFIDENCE. NE WIND
INCREASES...GUSTING TO 25-30 KT WITH SEAS BUILDING TO 5-7 FT.
VSBY RESTRICTIONS IN LIGHT RAIN AND PATCHY FOG MAINLY OVER THE
EASTERN WATERS.

SUNDAY NIGHT AND MONDAY...MODERATE CONFIDENCE. WINDS SHIFT TO N
AND BEGIN TO DIMINISH SUNDAY NIGHT. BY MONDAY...N WINDS SHIFT
BACK TO SE-S DURING THE DAY AS A WARM FRONT TRIES TO PASS. MAY
SEE SOME VSBY RESTRICTIONS MON AFTERNOON IN SCATTERED SHOWERS.
