AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE TAUNTON MA
203 PM EDT TUE AUG 13 2013

.SYNOPSIS...
AN APPROACHING COLD FRONT WILL BRING SHOWERS AND EMBEDDED
THUNDERSTORMS WITH LOCALLY HEAVY RAINFALL THROUGH THIS EVENING.
DRY AND SEASONABLE WEATHER RETURNS WEDNESDAY AND CONTINUES INTO
THE WEEKEND.

&&

.NEAR TERM /UNTIL 6 PM THIS EVENING/...
***SHOWERS AND EMBEDDED THUNDERSTORMS MAY BRING LOCALLY HEAVY
 RAINFALL/POOR DRAINAGE STREET FLOODING LATE THIS AFTERNOON***

2 PM UPDATE...MUCH OF THE RAIN HAS DISSIPATED OR MOVED OFFSHORE IN
THIS AREA. EXCEPTIONS TO THIS ARE SOUTHERN RHODE ISLAND AND
SOUTHEASTERN MASSACHUSETTS INCLUDING THE CAPE AND ISLANDS WHERE
STORMS MOVING NORTHEASTWARD FROM NEW JERSEY ARE TRACKING. THE
STRONGEST OF THESE STORMS REMAIN WELL SOUTH OF SOUTHERN NEW
ENGLAND...POSSIBLY ONLY CLIPPING THE SOUTHERN OUTER COASTAL
WATERS. THAT SAID...THIS IS VERY SIMILAR TO THE HRRR MODEL THAT
FORECASTS ADDITIONAL SHOWERS AND THUNDERSTORMS FORMING IN NEW YORK
STATE JUST AHEAD OF THE COLD FRONT. THESE STORMS HAVE DEVELOPED
JUST EAST OF LAKE ONTARIO SOUTHWARD INTO CENTRAL PENNSYLVANIA AND
WILL SLOWLY MAKE THEIR WAY EASTWARD. THESE ARE FORECAST NOT TO MOVE
INTO OUR AREA UNTIL CLOSE TO 00Z...AT WHICH POINT INSTABILITY IS
LIKELY TO BE MORE LIMITED THAN IT ALREADY IS. HOWEVER...THERE ARE
STARTING TO BE SOME INDICATIONS OF CLEARING ACROSS NEW YORK STATE
AND EVEN A BIT INTO THE CONNECTICUT VALLEY IN MASS AND
CONNECTICUT. IF THIS CLEARING CONTINUES...IT MAY PRODUCE ENOUGH
INSTABILITY TO SUSTAIN THESE STORMS.

IF THE STORMS SUSTAIN THEMSELVES...THERE IS GOOD POTENTIAL FOR
LOCALLY HEAVY RAINFALL AND POSSIBLY URBAN AND POOR DRAINAGE
FLOODING. IN ADDITION...THE ENVIRONMENT IS THE SAME HIGH
SHEAR...LOW CAPE ENVIRONMENT WE HAVE BEEN IN MUCH OF THE SUMMER.
THEREFORE...THERE IS A POTENTIAL FOR STRONG WINDS WITH THE
STRONGEST STORMS.

&&

.SHORT TERM /6 PM THIS EVENING THROUGH 6 PM WEDNESDAY/...
TONIGHT...
A FEW SHOWERS AND ISOLATED THUNDERSTORMS MAY LINGER DURING THE
EVENING ESPECIALLY ALONG THE COAST.  OTHERWISE...MUCH DRIER MID
LEVEL AIR WILL WORK INTO THE REGION BY LATE EVENING BRINGING AN END
TO MOST OF THE PRECIPITATION.  MAY SEE SOME PATCHY GROUND FOG
DEVELOP IN THE TYPICALLY PRONE LOCATIONS...ESPECIALLY IN AREAS THAT
SEE A FAIR AMOUNT OF RAIN TODAY.  LOW TEMPS WILL MAINLY BE IN THE
UPPER 50S AND LOWER 60S.

WEDNESDAY...
A MIXTURE OF CLOUDS/SUN ALONG WITH GUSTY NORTHWEST WINDS BEHIND THE
COLD FRONT ON WED.  LOW RISK OF A BRIEF SPRINKLE/SPOT SHOWER ACROSS
OUR FAR NORTHWEST ZONES...BUT BASICALLY A DRY AND BEAUTIFUL DAY
EXPECTED FOR THE MIDDLE OF AUGUST.  HIGH TEMPS WILL MAINLY BE IN THE
70S WITH LOW HUMIDITY.  IN FACT...SOME OF THE HIGHEST TERRAIN WILL
STRUGGLE TO REACH 70!

&&

.LONG TERM /WEDNESDAY NIGHT THROUGH TUESDAY/...
HIGHLIGHTS...
  * QUIET...SEASONABLE WEATHER WED THRU THE WEEKEND
  * POSSIBILITY OF SOME RAIN EARLY NEXT WEEK

OVERVIEW AND MODEL PREFERENCES...
13/00Z LONG RANGE GUIDANCE CONTINUES TO SHOW QUITE GOOD AGREEMENT
THROUGH MUCH OF THE LONG TERM. INITIAL WEAK CUTOFF IS PROGGED TO
SLIDE INTO THE CANADIAN MARITIMES AS A SECOND CUTOFF DIVES S FROM
HUDSON BAY IN THE PERSISTENT BROAD TROF OVER ERN CANADA AND THE
NORTHEAST CONUS. HOWEVER...THE LONGWAVE TROF AND THIS SECOND
CUTOFF LOOK TO HAVE LITTLE EFFECT ON THE REGION AS STRONG RIDGING
ALONG THE SOUTHERN HALF OF THE CONUS COMBINES WITH RIDGING IN THE
ATLANTIC TO YIELD SUBSIDENCE AND BROAD SFC HIGH PRES OVER THE
NORTHEAST. GIVEN THERE IS GOOD AGREEMENT BETWEEN BOTH OPERATIONAL
MODELS AND THEIR COUNTERPART ENSEMBLES...HAVE REASONABLY HIGH
CONFIDENCE THAT THIS HIGH PRES WILL YIELD A MOSTLY DRY FORECAST
THROUGH EARLY NEXT WEEK. GIVEN THIS...WILL USE A GFS/ECWMF BLEND
AS A BASELINE FOR THIS FORECAST UPDATE.

WED NIGHT INTO FRI...
HIGH PRES GRADUALLY SLIDES IN FROM THE W THROUGH THE PERIOD. WITH
THE HIGH PRES CENTER REMAINING W OF THE REGION...EXPECT US TO
REMAIN ON THE COOLER SIDE OF THE HIGH INITIALLY. H85 TEMPS RANGE
BETWEEN +8C AND ABOUT +11C...SO HIGHS SHOULD START THU AROUND THE
MID 70S...INCREASING TO THE UPPER 70S AND LOW 80S BY FRI AFTER
SOME AIRMASS MODIFICATION. OVERNIGHT MINS WILL BE ON THE COOL SIDE
WITH LOW HUMIDITY /AND THEREFORE LOW DWPTS/ WITH LIGHT FLOW AND
CLEAR SKIES. EXPECTING MINS DIPPING AS LOW AS THE MID 40S IN
NORMALLY COOLER SPOTS. MID 50S IN THE WARMER SPOTS.

THIS COMING WEEKEND...
A WARM FRONT IS EXPECTED TO BEGIN A GRADUAL SLIDE TO THE N
THROUGH THE WEEKEND...BUT WITH HIGH PRES IN PLACE OVER THE REGION
AND VERY SLOWLY SLIDING TO THE E...EXPECTING MOSTLY DRY CONDITIONS
ACROSS SRN NEW ENGLAND DESPITE THIS APPROACHING FRONT. GFS
CURRENTLY SUGGESTS HIGHEST POTENTIAL FOR SOME PRECIP...BUT IT TOO
KEEPS MOST OF ITS GENERATED QPF TO THE W. MID LVL TEMPS DO
INCREASE SOMEWHAT...REACHING +10 TO +13C...SO TEMPS LEAN NEAR TO
SLIGHTLY WARMER THAN NORMAL.

EARLY NEXT WEEK...
DIFFERENCES IN THE TIMING OF A STRONGER SHORTWAVE EFFECTING THE
REGION GIVES WAY TO LOWER CONFIDENCE HERE...BUT IT APPEARS THAT
THERE WILL BE A BIT HIGHER CHANCE FOR SOME PRECIP PARTICULARLY BY
TUE. WILL BE INCREASING TO SOME SLIGHT CHANCE POPS...CLOSER TO THE
ECWMF SOLUTION...WHICH SUGGESTS THE WARM FRONT LIFTS FAR ENOUGH N
TO AFFECT THE REGION WITH THIS SHORTWAVE PASSAGE.

&&

.AVIATION /17Z TUESDAY THROUGH SATURDAY/...
FORECASTER CONFIDENCE LEVELS...

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

OVERVIEW...MODERATE CONFIDENCE TODAY AND TONIGHT.  HIGH CONFIDENCE
WEDNESDAY AND WEDNESDAY NIGHT.

THROUGH 00Z...RAIN WITH EMBEDDED THUNDERSTORMS ALONG SOUTH
COAST...CAPE...AND ISLANDS. ISOLD TO SCT SHRA ELSEWHERE. GENERALLY
IFR IN THE MAIN BATCH OF RAIN WITH IFR TO VFR CONDITIONS
ELSEWHERE. IFR CONDITIONS WILL BE MOSTLY DUE TO POCKETS OF
HEAVIER RAIN. EXACT TIMING REMAINS UNCERTAIN.

TONIGHT...LOW PROBABILITY OF A LINE OF SHOWERS AND THUNDERSTORMS
MOVING INTO WESTERN ZONES RIGHT AROUND 00Z. OTHERWISE...MAY SEE
SOME LINGERING LOW CLOUDS AND FOG PATCHES PERSIST AT SOME
/ESPECIALLY EASTERN/ TERMINALS INTO THE OVERNIGHT HOURS. AREAL
COVERAGE OF LOW CLOUDS AND FOG PATCHES ARE UNCERTAIN.

WEDNESDAY...ANY LEFTOVER MVFR-IFR CONDITIONS IN SCATTERED LOW
CLOUDS/FOG PATCHES WILL IMPROVE TO VFR NOT LONG AFTER SUNRISE.
OTHERWISE...VFR CONDITIONS.

WEDNESDAY NIGHT...VFR.

KBOS TERMINAL...HIGH CONFIDENCE IN TRENDS. LOW CONFIDENCE IN
TIMING. MAY SEE BOUNCING BETWEEN VFR AND LOWER CATEGORIES WITH
RAIN THIS EVENING.

KBDL TERMINAL...MODERATE CONFIDENCE IN TRENDS.  LOW CONFIDENCE IN
TIMING.

OUTLOOK...THURSDAY THROUGH SATURDAY...

HIGH CONFIDENCE.  VFR.

&&

.MARINE...
FORECASTER CONFIDENCE LEVELS...

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

TODAY AND TONIGHT...HIGH CONFIDENCE.  WINDS AND SEAS WILL REMAIN
BELOW SCA THRESHOLDS WITH A RELATIVELY WEAK PRESSURE GRADIENT IN
PLACE.  THE MAIN CONCERN EARLY THIS MORNING WILL BE FOR DENSE FOG
ACROSS OUR SOUTHERN WATERS.  THIS FOG SHOULD BURN OFF TO AT LEAST
SOME DEGREE BY MID TO LATE MORNING. THE OTHER CONCERN WILL BE FOR
EMBEDDED THUNDERSTORMS TO WORK ACROSS THE WATERS...MAINLY THIS
AFTERNOON AND EVENING.

WEDNESDAY...MODERATE CONFIDENCE.  NORTHWEST WIND GUSTS OF 25 KNOTS
ARE EXPECTED NEAR SHORE WITH GOOD MIXING BEHIND THE COLD FRONT.  ITS
3RD PERIOD SO DID NOT GO WITH ANY HEADLINES AT THIS POINT...BUT
LATER SHIFTS MAY NEED TO CONSIDER A SCA FOR SOME OF OUR NEAR SHORE
WATERS.  MAY ALSO SEE SOME 3 TO 5 FOOT SEAS DEVELOP ACROSS OUR
SOUTHERN MOST ATLANTIC WATERS...WHICH MAY ALSO NEED TO BE CONSIDERED
FOR HEADLINES.

OUTLOOK...WEDNESDAY THROUGH SATURDAY...

HIGH CONFIDENCE.  QUIET BOATING WEATHER EXPECTED.  WINDS WILL SHIFT
DIRECTION AS HIGH PRESSURE BUILDS OVER SOUTHERN NEW ENGLAND AND THE
WATERS BUT WILL REMAIN BELOW 25 KTS...SAVE FOR POSSIBLY WED
EVENING.
