AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE TAUNTON MA
420 PM EDT TUE MAY 12 2015

.SYNOPSIS...
A FEW SCATTERED SHOWERS AND STORMS ARE POSSIBLE THIS EVENING...
GIVING WAY TO A COOL AND LESS HUMID NIGHT TONIGHT. LARGE HIGH
PRESSURE WILL BUILD ACROSS THE EASTERN U.S. WITH DRIER WEATHER
THROUGH THE REMAINDER OF THIS WEEK. AN APPROACHING WARM FRONT
COULD BRING SCATTERED SHOWERS THIS WEEKEND.

&&

.NEAR TERM /UNTIL 6 AM WEDNESDAY MORNING/...
WE KNEW IT WAS GOING TO BE RACE BETWEEN DRIER AIR WORKING IT/S WAY
INTO THE COLUMN FROM THE NW AND LEFTOVER INSTABILITY AHEAD OF A
COLD FRONT CURRENTLY JUST NW OF THE BOX CWA. SO FAR...THE DRY AIR
IS WINNING...WE HAVE NOTED LOW LVL DWPTS DROPPING RAPIDLY INTO THE
50S WITH MIXING IN WRN CT/MA. K VALUES ARE ALREADY DROPPING BACK
INTO THE 20S NOW AS WELL...SO OVERALL DRY AIR HAS BEEN LIMITING
COVERAGE OF CONVECTION E OF THE FRONT. ANY SMALL LOW-TOPPED CELLS
THAT HAVE DEVELOPED HAVE QUICKLY DIMINISHED...IN SPITE OF THE
AVAILABLE SHEAR. THERE HAS BEEN CONVECTION...ALBEIT LOW TOPPED
CLOSELY ASSOCIATED WITH THE FRONT ITSELF...WHICH HAS PRODUCED SOME
/ALTHOUGH VERY LITTLE/ IC LIGHTNING. THERE IS A WEAKENING RIDGE
OF HIGHER THETA-E AIR IN ERN MA AND RI...AND THIS MAY BE THE AREA
TO WATCH FOR THE NEXT COUPLE OF HOURS. BUT WITH THE SUN BEGINNING
TO SET AFTER 1800L...SUSPECT IT WILL BE VERY DIFFICULT TO GET
SIGNIFICANT CONVECTION FROM THEREAFTER. WILL CONTINUE TO MONITOR
THE ACTUAL FROPA...BUT WITH THIS OFFSHORE NOT LONG AFTER 00Z /OR
2000L/ WILL LIKELY SEE FAIRLY RAPID IMPROVEMENT AND DISSIPATION OF
ANY REMAINING -SHRA.

OTHERWISE TONIGHT...AFTER SKIES GENERALLY CLEAR...WE FINALLY WORK
IN ENOUGH LOWER DWPT AIR TO RELIEVE THE AREA OF THE FOG/STRATUS
WHICH HAS DEFINED OUR OVERNIGHTS RECENTLY. DWPTS SHOULD FALL BACK
INTO THE LOW 40S BY MORNING BUT A BUILDING PRES GRADIENT AHEAD OF
HIGH PRES TO THE W WILL LIKELY KEEP ENOUGH WESTERLY WINDS TO LIMIT
RADIATIONAL COOLING. THEREFORE...ALTHOUGH MINS WILL BE /AND FEEL/
MUCH COOLER TONIGHT...THEY ARE LIKELY TO STOP IN THE LOW 50S.

&&

.SHORT TERM /6 AM WEDNESDAY MORNING THROUGH WEDNESDAY NIGHT/...
TONIGHT...
DRY HIGH PRES NEARLY 1030HPA WILL BE NOSING IN FROM THE W. GOOD
AFTERNOON MIXING WILL ALLOW BL TO REACH LIKELY ABOVE H85...WHERE
TEMPS WILL BE DROPPING THROUGH THROUGH TO ABOUT +2C BY THE
AFTERNOON. GIVEN THE HIGHER MIXING...AND FACT THAT GREENUP IS
STILL IN ITS RELATIVELY EARLY STAGES...ITS LIKELY HIGHS WILL
EXCEED CURRENT 2M TEMP SUGGESTIONS OF MID LOW-MID 60S.
THEREFORE...HAVE MAINLY UPPER 60S AND LOW 70S FOR HIGHS TOMORROW.
THE BUILDING HIGH PRES ALSO SUGGESTS DECENT ISALLOBARIC COUPLET SO
IT/S LIKELY WINDS WILL BE A FACTOR...MAINLY 10-15 MPH WITH GUSTS
25-30 MPH LIKELY. THIS WILL MAKE FIRE WEATHER THE PRIMARY CONCERN
GIVEN A RELATIVE LACK OF WIDESPREAD RAINFALL FROM TUE CONVECTION.
SEE THE SECTION BELOW FOR THIS.

TOMORROW NIGHT...
HIGH PRES WILL BE CONTINUALLY NOSING IN ALLOWING THE OVERNIGHT
PRES GRADIENT TO SLACKEN SUBSTANTIALLY. THE LOSS OF DIURNAL
HEATING WITH LITTLE MOISTURE THROUGH THE COLUMN SHOULD ALSO LEAD
TO A CLEAR NIGHT. WITH AFTERNOON MIXING ALLOWING DWPTS TO DROP
BACK INTO THE UPPER 20S AND LOW 30S...WE MAY HAVE TO BE ON THE
LOOKOUT FOR LOCALIZED FROST DEVELOPMENT IN TYPICALLY COOLER
VALLEYS. NOT CONFIDENT ENOUGH FOR HEADLINES AT THIS TIME...BUT
EVEN SOME OF THE WARMER GUIDANCE IS SUGGESTING A FEW PLACES
APPROACH THE MID 30S AT 2M.

&&

.LONG TERM /THURSDAY THROUGH TUESDAY/...
HIGHLIGHTS...

* HIGH PRESSURE BRINGS DRY WEATHER THROUGH THE END OF THIS WEEK
* RAIN POSSIBLE LATE FRI INTO THIS WEEKEND
* ABOVE NORMAL TEMPERATURES CONTINUE INTO EARLY NEXT WEEK

12/12Z GUIDANCE REMAINS IN DECENT AGREEMENT THROUGH THIS PORTION OF
THE FORECAST. THE FIRST HALF OF THE FORECAST PERIOD IS RATHER QUIET
WITH HIGH PRESSURE BUILDING OVER SOUTHERN NEW ENGLAND. AS WE MOVE
INTO THIS WEEKEND...AN UPPER LEVEL RIDGE STARTS BUILDING OVER THE
REGION. A LOW PRESSURE MOVES FROM THE GREAT LAKES...THROUGH NEW
ENGLAND EARLY THIS WEEKEND.

THURSDAY THROUGH FRIDAY...HIGH PRESSURE BUILDS INTO SOUTHERN NEW
ENGLAND...PASSING SOUTH OF THE REGION THURSDAY NIGHT AND FRIDAY.
QUIET WEATHER IS EXPECTED THROUGH THIS PERIOD WITH TEMPERATURES
RETURNING TO ABOVE NORMAL.

FRIDAY NIGHT INTO SATURDAY...RAIN SHOWERS DEVELOP AS A WARM FRONT
APPROACHES FROM THE SOUTH. NOT CERTAIN THIS FRONT WILL MOVE
COMPLETELY THROUGH OUR REGION. AS SUCH...HAVE LOW CONFIDENCE ON THE
AMOUNT OF AVAILABLE INSTABILITY FOR THUNDERSTORMS. WILL JUST KEEP A
MENTION OF SHOWERS IN THE FORECAST AT THIS TIME.

SUNDAY INTO TUESDAY...THIS PORTION OF THE FORECAST WILL LARGELY
DEPEND ON THE AMPLIFICATION OF AN UPPER RIDGE OVER THE EASTERN USA.
THERE COULD BE ISOLATED TO SCATTERED SHOWERS...MAINLY DURING THE
PEAK HEATING HOURS. RAINFALL CHANCES ARE GREATER TUESDAY AS A COLD
FRONT APPROACHES FROM THE WEST.

&&

IN SPOTS THROUGH THE AFTERNOON/EVENING. FEEL THAT TSRA WILL BE TOO
WIDESPREAD TO INCLUDE IN THE TAF.

SHORT TERM /THROUGH WEDNESDAY NIGHT/...HIGH CONFIDENCE.

TONIGHT AND TOMORROW...
REMNANT SWELLS FROM ANA CONTINUE TO IMPACT MAINLY THE S...AND SE
WATERS...BUT ARE LIKELY TO SPILL INTO THE E WATERS OVERNIGHT. SEAS
WILL GENERALLY RANGE FROM 5-9 FT BUT BEGIN TO DECLINE EARLY IN THE
MORNING AFTER WINDS SHIFT TO THE W. THESE SEAS WILL CONTINUE TO
DECLINE TOMORROW...BUT SUSPECT NEAR SHORE WINDS MAY APPROACH 25 KT
AT TIMES. THEREFORE...HAVE EXTENDED ALL SMALL CRAFT ADVISORIES
THROUGH TOMORROW. ANY REMAINING FOG SHOULD DISSIPATE FINALLY THIS
EVENING.

TOMORROW NIGHT...
WINDS AND SEAS BOTH DIMINISH TOMORROW NIGHT SUCH THAT ANY
REMAINING SMALL CRAFT ADVISORIES CAN BE DROPPED.

OUTLOOK...THURSDAY THROUGH SUNDAY...

THURSDAY THROUGH FRIDAY...HIGH CONFIDENCE. QUIET BOATING WEATHER
EXPECTED AS HIGH PRESSURE BUILDS OVER SOUTHERN NEW ENGLAND.

FRIDAY NIGHT INTO SUNDAY...LOW CONFIDENCE. WHILE CONDITIONS ARE
CURRENTLY EXPECTED TO REMAIN BELOW SMALL CRAFT CRITERIA...WINDS
AND SEAS WILL BE INCREASING AS A WARM FRONT APPROACHES THE WATERS.
5 FOOT SEAS IN PARTICULAR ARE NOT OUT OF THE QUESTION ACROSS THE
OUTER COASTAL WATERS.

&&

.FIRE WEATHER...
TOMORROW...
CONDITIONS RIPE FOR ELEVATED FIRE WEATHER. ONLY CONTINGENT WILL BE
TO MONITOR RAINFALL ACROSS THE EVENING FROM ANY -SHRA/TSRA THAT
DEVELOP ACROSS THE AREA THIS EVENING. HOWEVER...IN SPITE OF ANY
RAINFALL...IT APPEARS RH VALUES WILL DROP TO THE MID 20 PERCENT
RANGE TOMORROW AFTERNOON WHILE W-NW WINDS OF 10-15 MPH WITH GUSTS
25-30 MPH ARE EXPECTED. ACTUALLY TEMPS WILL NOT BE AS WARM AS THE
PREVIOUS FEW DAYS...MAINLY IN THE UPPER 60S AND LOW 70S BY LATE
AFTERNOON...BUT SUNSHINE IS EXPECTED FOR NEARLY ALL DAY. CURRENTLY
A FIRE WEATHER WATCH IS IN PLACE FOR THESE CONDITIONS...AND IT IS
LIKELY THEY WILL BE UPGRADED TO RED FLAG WARNINGS OVERNIGHT.

THURSDAY AND FRIDAY...DRY WEATHER CONDITIONS WILL CONTINUE WITH
MINIMUM RH VALUES DROPPING INTO THE 20 TO 30 PERCENT RANGE. SINCE
HIGH PRESSURE WILL BE OVERHEAD...WINDS WILL BE LIGHT AND
VARIABLE...ALTHOUGH GUSTS COULD REACH 10-15 MPH.
