AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE TAUNTON MA
1012 AM EDT THU AUG 22 2013

.SYNOPSIS...
CONTINUED WARM AND MUGGY CONDITIONS AHEAD OF A SERIES OF WET
WEATHER DISTURBANCES TODAY INTO FRIDAY. SCATTERED SHOWERS AND
THUNDERSTORMS EXPECTED...CLEARING OUT BY AS LATE AS FRIDAY NIGHT.
THEREAFTER DRY AND NEAR SEASONABLE WEATHER WILL RETURN THIS
WEEKEND AS HIGH PRESSURE BUILDS ACROSS THE REGION. MORE HUMID
CONDITIONS AND PERIODS OF UNSETTLED WEATHER MOVES IN NEXT WEEK AS
A WARM FRONT MOVES INTO THE REGION.

&&

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

1015 AM UPDATE...
FOG OVER THE REGION CONTINUES TO LINGER AS SOUTHERLY FLOW
CONTINUES TO STREAM IN MOISTURE ALONG THE COASTS. OTHERWISE FOCUS
TURNS TO SCATTERED SHOWERS AND THUNDERSTORMS CURRENTLY OVER THE
NYC AND LONG ISLAND. THESE SHOWERS WILL SLOWLY MOVE ACROSS THE
SOUTHERN HALF OF THE REGION AS A GOOD AMOUNT OF DRY AIR IS IN
PLACE ACROSS THE NORTH. THIS IS INDICATED BY THE K INDEX AND 700MB
MOISTURE FIELDS. TRENDED THE NEAR TERM TOWARDS THE 12Z NAM AND
HRRR PARAMETERS AS THEY HAVE AN EXCELLENT HANDLE ON CURRENT RADAR
IMAGERY. BELIEVE PRECIP SHOULD BEGIN TO ENTER THE SOUTHERN
HARTFORD COUNTY WITHIN THE HOUR AND SLOWLY WILL MOVE TOWARDS THE
REGION BY THE AFTERNOON HOURS. EXPECT MAIN THREATS TO BE LIGHTNING
AND HEAVY RAINFALL AS PWAT VALUES ARE AROUND 1.5.

PREVIOUS DISCUSSION...

FOCUS WILL BE ON THE DEAMPLIFYING MID-LEVEL LOW PRESSURE TRACKING
EAST ACROSS THE DELMARVA OUT TO SEA. SQUEEZING UP AGAINST ATLANTIC
HIGH PRESSURE AND PUSHED BY A STRONGER SHORTWAVE AND TROUGH AXIS
APPROACHING FROM THE EASTERN GREAT LAKES WILL YIELD AMPLIFICATION
OF MID- TO UPPER-LEVEL TROPOSPHERIC WINDS PROMOTING GREATER
DIFFLUENCE ALOFT. IN RESPONSE...SHOULD SEE AN ENHANCEMENT OF
SOUTHERLY FLOW WITHIN THE LOW-LEVELS ADVECTING MORE MUGGY
CONDITIONS INTO SOUTHERN NEW ENGLAND AGAINST DRIER AIR /GUSTS UP
TO 20 MPH ALONG THE SOUTH COAST/. SUBSEQUENT MOISTENING TO THE
WET-BULB OF THE ATMOSPHERIC PROFILE SHOULD ALLOW THE BUILD UP OF
ELEVATED INSTABILITY.

FEEL ANY ACTIVITY TODAY WILL BE LOCALIZED MAINLY SOUTH AND WEST IN
REGIONS OF FAVORABLE LIFT ALOFT COLLOCATED WITH AREAS OF LOW-LEVEL
CONVERGENCE THAT CAPITALIZE ON THE GROWING INSTABILITY...ESPECIALLY
IF THE BOUNDARY LAYER HAS AN OPPORTUNITY TO DESTABILIZE. STILL
DIFFICULT TO PIN-POINT...BUT FEEL AREAS NORTH AND EAST MAY REMAIN
UNDER THE INFLUENCE OF DRIER AND SINKING AIR.

GREATER CONFIDENCE WITH THE LATEST HRRR AND 22.0Z NAM HIGHLIGHTING
SOME EARLY MORNING ACTIVITY COLLOCATED WITH THE NOSE OF A LOW-LEVEL
JET AXIS JUST ABOVE THE DECOUPLED BOUNDARY LAYER. ACTIVITY OCCURRING
ACROSS NORTHEAST PENNSYLVANIA SHOULD FOCUS EASTWARD WITH TIME. BUT
OTHERWISE...A MAJORITY OF THE FORECAST AREA MAY SIMPLY REMAIN PARTLY
CLOUDY AND DRY...ALLOWING HIGHS TO GET INTO THE MID- TO UPPER-80S...
WITH A FEW LOCATIONS AT OR ABOVE THE 90 DEGREE MARK FOR A SECOND DAY
IN A ROW.

CONSIDERING A WEAK SHEAR ENVIRONMENT WITH MODEST INSTABILITY ALONG
WITH NEAR-ZERO CORFIDI VECTORS AND A WEAK MEAN ATMOSPHERIC FLOW
AROUND 15 MPH...MAIN THREATS ASSOCIATED WITH ANY STORMS APPEAR TO
BE HEAVY RAIN AND POSSIBLE NUISANCE FLOODING /PWATS CONTINUE TO
RANGE AROUND 1.5 TO 1.75 INCHES/. COULD SEE SOME GUSTY WINDS
SHOULD THE BOUNDARY LAYER MIX-OUT WITH INVERTED-V PROFILES.

ACTIVITY ALONG THE UPSTREAM COLD FRONT WILL NOT PUSH INTO THE
FORECAST REGION UNTIL EVENING.

&&

.SHORT TERM /6 PM THIS EVENING THROUGH FRIDAY NIGHT/...
TONIGHT...

STRONGER SHORTWAVE AND TROUGH AXIS WITH ATTENDANT SURFACE COLD FRONT
WILL SWEEP THROUGH THE REGION REACHING SOUTHEAST MASSACHUSETTS BY
MORNING. ANTICIPATING SHOWERS AND THUNDERSTORMS ALONG AND AHEAD OF
THE COLD FRONT AIDED BY STRONG FRONTOGENETICAL LIFT. INITIALLY
PUSHING INTO WESTERN NEW ENGLAND BY EVENING...ACTIVITY LOOKS TO
DIMINISH EASTWARD TOWARDS BY MIDNIGHT INTO MORNING AS BETTER
DYNAMICS ALOFT LIFT NORTH AND EAST PARENT WITH THE MID-LEVEL LOW.

WITH A STABILIZING BOUNDARY LAYER PROFILE...FEEL ANY STORMS WILL BE
MAINLY ASSOCIATED WITH HEAVY RAIN. LESSER CONFIDENCE FOR NUISANCE
FLOODING AS THE BETTER PWAT ENVIRONMENT WILL BE WELL SOUTH AND EAST
OFFSHORE OF THE REGION. LOWS AROUND THE MID-60S.

FRIDAY...

SURFACE COLD FRONT SLOWS OFFSHORE...STALLING SOUTH OF SOUTHERN NEW
ENGLAND. CLOUDS AND SHOWERS WILL LINGER FOR THE FAR SOUTH-SOUTHEAST
PORTIONS OF THE FORECAST AREA. NORTHWEST FLOW PREVAILS PUSHING
COOLER AND DRIER AIR SOUTH WITHIN THE LOW- TO MID-LEVELS.

EXPECTING DEEP BOUNDARY LAYER MIXING UP TO H8 LENDING TO SCATTERED
TO BROKEN DIURNAL CUMULUS AND THE POSSIBILITY FOR SOME SPOTTY
SHOWERS CAPITALIZING ON THE LIFT OF MINOR ELEVATED INSTABILITY AHEAD
OF A REINFORCING SECONDARY COLD FRONT. WILL INSERT SLIGHT CHANCE
POPS FOR A MAJORITY OF THE FORECAST REGION FOR THE MIDDAY INTO
AFTERNOON PERIOD. WILL ALSO SEE THE MIX-DOWN OF DRIER AIR AND FASTER
MOMENTUM. WIND GUSTS AROUND 15 MPH EXPECTED WITH HIGHS AROUND THE
LOW-80S...COOLER ALONG THE SHORES AND HIGHER ELEVATIONS.

FRIDAY NIGHT...

REINFORCING COLD FRONT PUSHES WELL OFFSHORE PARENT WITH ANOTHER MID-
LEVEL TROUGH AXIS SWEEPING ACROSS NEW ENGLAND. WINDS BACK MORE
NORTHERLY CONTINUALLY ADVECTING MORE COOLER AND DRIER AIR SOUTHWARD
OUT OF CANADA. LOOKING AT A POTENTIALLY CHILLY NIGHT SHOULD
CONDITIONS REMAIN MOSTLY CLEAR. LOWS AROUND THE MID-50S.

&&

.LONG TERM /SATURDAY THROUGH WEDNESDAY/...
HIGHLIGHTS...

* DRY AND COOLER SAT...THEN WARMER SUNDAY
* BECOMING MORE HUMID NEXT WEEK WITH UNSETTLED WEATHER POSSIBLE FROM
  TIME TO TIME.

OVERVIEW...
GUIDANCE IN GOOD AGREEMENT ON OVERALL PATTERN DURING THE EXTENDED
PERIOD. MID LEVEL TROF WHICH WILL BRING COOLER WEATHER TO START THE
WEEKEND WILL BE EXITING THE REGION BY SUNDAY. MODELS AGREE ON AN
ANOMALOUS AND EXPANSIVE MID LEVEL RIDGE BUILDING ACROSS THE CENTRAL
CONUS DURING MUCH OF THE PERIOD WITH SNE REMAINING ON THE SOUTHERN
EDGE OF THE POLAR JET WITH MAINLY NW FLOW ALOFT.  THIS WILL KEEP THE
SIGNIFICANT HEAT WEST OF SNE AND ALSO MAKE US SUSCEPTIBLE TO
OCCASIONAL IMPULSES IN NW FLOW BEGINNING NEXT WEEK. THE TIMING AND
AMPLITUDE OF INDIVIDUAL SHORTWAVES WILL DETERMINE THE COVERAGE AND
INTENSITY OF SHOWERS AND THUNDERSTORMS...BUT THE THREAT WILL EXIST
SOMETIME FROM LATE MON INTO WED.

SATURDAY AND SUNDAY...
STRONG HIGH PRES BUILDS ACROSS SNE GRADUALLY SHIFTING TO THE S ON
SUNDAY.  FOR SAT...NEARBY MID LEVEL TROF AND COLD POOL ACTING ON LOW
LEVEL MOISTURE WILL LIKELY BRING AT LEAST SCT-BKN CU BUT THE
MOISTURE IS SHALLOW SO DRY WEATHER EXPECTED.  LESS CU ON SUNDAY AS
MID LEVEL TEMPS WARM. TEMPS WILL BE A FEW DEGREES BELOW NORMAL
SAT...MOSTLY IN THE MID/UPPER 70S THEN WARMING INTO UPPER 70S AND
LOWER 80S SUNDAY IN RESPONSE TO INCREASING MID LEVEL TEMPS.

MONDAY...
SOME DIFFERENCES BETWEEN GFS AND ECMWF BEGIN TO SHOW UP REGARDING
THE EASTWARD EXTENT OF THE WARM FRONT. GFS APPEARS TO MOVE THE WARM
FRONT THROUGH TOO QUICKLY. PREFER THE ECMWF KEEPING THE FRONT TO THE
WEST GIVEN THE NW FLOW ALOFT. MOST OF THE REGION SHOULD REMAIN DRY
ALTHOUGH CANT RULE OUT A FEW SHOWERS OR A THUNDERSTORM ACROSS W
ZONES LATE IN THE DAY AS MOISTURE INCREASES FROM THE WEST.

MONDAY NIGHT INTO WEDNESDAY...
IT APPEARS FRONTAL BOUNDARY MAY GET HUNG UP NEAR SNE DURING THIS
PERIOD. THIS WILL BRING THE THREAT OF SHOWERS AND THUNDERSTORMS FROM
TIME TO TIME BUT WE HAVE LOW CONFIDENCE IN TIMING AS THERE ARE
DIFFERENCES IN THE MODELS. HUMIDITY WILL BE INCREASING ALTHOUGH THE
HEAT WILL REMAIN TO THE WEST WITH TEMPS MOSTLY NEAR SEASONABLE
NORMALS.

&&

.AVIATION /14Z THURSDAY THROUGH MONDAY/...
FORECASTER CONFIDENCE LEVELS...

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

OVERVIEW /THROUGH FRIDAY NIGHT/...MODERATE CONFIDENCE.

AREAS OF MVFR/IFR FOG AND STRATUS WILL BURN OFF BY MID
MORNING. SHRA/TSRA WILL BE ON THE INCREASE FROM THE SOUTH AND
WEST BY LATE MORNING INTO THE AFTERNOON HOURS. MENTIONED VCSH FOR
NOW WITH OVERWHELMING UNCERTAINTY ON THE EVOLUTION AND POTENTIAL
IMPACTS OF SHRA/TSRA. SOUTHWEST WINDS PREVAILING WITH GUSTS UP TO
AROUND 20 KTS.

ACTIVITY CLEARS UP INTO FRIDAY MORNING WITH A COLD FRONT SWEEPING
ACROSS THE TERMINALS...WINDS BACKING WEST-NORTHWEST. MAY SEE A
SPOT SHRA/TSRA DURING THE DAY FRIDAY...BUT A REINFORCING COLD
FRONT WITH NORTH-NORTHWEST FLOW TO THE REAR SHOULD PUSH ALL
REMAINING ACTIVITY OFFSHORE.

KBOS TERMINAL...HIGH CONFIDENCE IN TAF. NO EXPECTATION FOR A SEA-
BREEZE.

KBDL TERMINAL...HIGH CONFIDENCE IN TAF. SHRA/TSRA POSSIBLE BY THE
LATE MORNING HOURS.

OUTLOOK...SATURDAY THROUGH MONDAY...

HIGH CONFIDENCE. MOSTLY VFR WITH SCT-BKN DIURNAL CU. LATE
NIGHT/EARLY MORNING PATCHY MVFR/IFR FOG POSSIBLE IN THE CT VALLEY.
WIDELY SCT SHOWERS/TSTMS POSSIBLE WESTERN AREAS LATE MON.

&&

.MARINE...
FORECASTER CONFIDENCE LEVELS...

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

OVERVIEW /THROUGH FRIDAY NIGHT/...MODERATE CONFIDENCE.

WINDS AND SEAS TO REMAIN BELOW SMALL CRAFT ADVISORY LEVELS. WORTHY
OF MENTION THAT SOUTHWEST WINDS WILL INCREASE WITH GUSTS UP TO 20
KTS POSSIBLE TODAY MAINLY ALONG THE SOUTH SHORE. SHOWERS AND
THUNDERSTORMS MAY BE ON THE INCREASE AHEAD OF A SURFACE COLD FRONT
ANTICIPATED TO SWEEP INTO THE WATERS CLOSER TO FRIDAY MORNING AND
CLEARING OUT BY FRIDAY LATE. BEHIND THE FRONT...WINDS WILL BACK
OUT OF THE NORTHWEST.

OUTLOOK...SATURDAY THROUGH MONDAY...

HIGH CONFIDENCE.

EXPECT WINDS AND SEAS TO REMAIN BELOW SCA THRESHOLDS FOR MOST OF THE
PERIOD. HOWEVER...SW WINDS COULD GUST TO 20+ KTS MON/MON NIGHT WITH
SEAS POSSIBLY BUILDING TO 5 FT OVER OUTER SOUTHERN WATERS.
