AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE TAUNTON MA
347 PM EDT SAT AUG 15 2015

.SYNOPSIS...
SCATTERED SHOWERS AND THUNDERSTORMS WILL COME TO AN END TONIGHT AS
A WEAK COLD FRONT MOVES OFFSHORE. HIGH PRESSURE WILL BRING HUMID
AND WARM WEATHER TOMORROW. SUMMER HEAT AND HUMIDITY WILL LIKELY
PERSIST INTO NEXT WEEKEND...AS HIGH PRESSURE HOLDS IN PLACE ALONG
THE EASTERN SEABOARD. DURING THIS TIME...THERE WILL BE THE CHANCE
FOR SHOWERS AND THUNDERSTORMS ASSOCIATED WITH A SERIES OF WEAK
FRONTAL DISTURBANCES.

&&

.NEAR TERM /UNTIL 6 AM SUNDAY MORNING/...
345 PM UPDATE...

SCATTERED SHOWERS AND THUNDERSTORMS CONTINUE TO DEVELOP ACROSS NH
AND NORTHERN MASS. THIS IS DUE TO APPROACHING SHORTWAVE FROM
NORTHERN NY AS WELL AS LINGERING WAVE INTO COASTAL MAINE/NH. BETWEEN
THE TWO OF THESE WAVES IS WHERE THE STORMS HAVE FIRED. ML CAPE
VALUES HAVE INCREASED TO 1500-2000 J/KG AND WITH K VALUES ABOVE
34...ANTICIPATE THE STORMS TO CONTINUE THROUGH THE REST OF THE
AFTERNOON.

BIGGEST THREAT WITH THESE STORMS WILL BE LOCALLY HEAVY RAINFALL.
PWAT VALUES HAVE INCREASED ABOVE 1.7 INCHES...AND WITH WEAK WINDS
ALOFT THESE STORMS WILL BE MOVING AROUND 10 KTS OR LESS. SHEAR
VALUES ARE WEAK AS WELL...LESS THAN 20KTS WHICH WILL INHIBIT STORMS
TO MAINTAIN THEMSELVES. THESE STORMS WILL BE MORE OF THE POP-
UP/PULSE VARIETY WHERE THE OUTFLOW MAY HELP DEVELOP A NEW STORMS.
THERE IS THE POTENTIAL FOR TRAINING ALONG THE SURFACE TROUGH/FRONT
AS FLOW ALOFT IS PARALLEL WITH THE FRONT. IF THAT IS THE CASE WE MAY
NEED TO ISSUE LOCAL FLOOD PRODUCTS LATER THIS AFTERNOON. FLASH FLOOD
GUIDANCE IS QUITE HIGH...AROUND 2-3 INCHES WITHIN AN HOURS.

THROUGH THE REST OF THE AFTERNOON ANTICIPATE THESE
SHOWERS/THUNDERSTORMS TO CONTINUE TO DEVELOP AS SURFACE TROUGH
APPROACHES THE REGION. COVERAGE WILL BE SCATTERED WITH HEAVY RAIN
AND LIGHTNING BEING THE MAIN THREAT. STILL CANT RULE OUT THE
POTENTIAL OF SOME GUSTY WINDS DUE TO INVERTED V PROFILE. HOWEVER
WINDS ALOFT ARE ABOUT 20 KTS...SO WE COULD SEE GUSTS NEAR 25 MPH.

STILL CONCERN ABOUT THE SOUTH COAST WHICH WILL HAS DRY AIR MOVING IN
THE MID-LEVELS WHICH COULD KEEP THEM TOTALLY DRY. THE SEA BREEZE HAS
ALSO PUSHED THE MARINE STABLE AIR WELL INTO SOUTHERN RI AND SE MASS.
HOWEVER MAY NEED TO WATCH FOR THE POTENTIAL FOR STORMS TO DEVELOP
ALONG THE SEA BREEZE BOUNDARY AND TRAIN AS WELL.

TONIGHT...

LINGERING SHOWERS WITH ISOLATED THUNDER WILL CONTINUE INTO THE
EVENING HOURS BEFORE SURFACE TROUGH PUSHES OFFSHORE. OTHERWISE
SHOULD BE A FAIRLY QUIET BUT MILD NIGHT WITH TEMPERATURES IN THE MID
60S. THE URBAN CORRIDORS OF BOS AND PVD WILL BE IN THE LOW 70S.

DEWPOINTS CONTINUE TO REMAIN IN THE MID TO UPPER 60S AND WITH
INCREASE LOW LEVEL MOISTURE FROM RECENT RAINFALL COULD SEE PATCHY
FOG DEVELOP. BEST LOCATIONS WILL BE ACROSS LOW-LYING AREAS.

&&

.SHORT TERM /6 AM SUNDAY MORNING THROUGH 6 PM SUNDAY/...

BUILDING HIGH PRESSURE AND MID-LEVEL RIDGE WILL BUILD ACROSS THE
REGION TOMORROW. TEMPERATURES WILL BE SIMILAR TO TODAY OR PERHAPS A
DEGREE OR TWO WARMER AS 850 MB TEMPS ALOFT WILL BE AROUND 16-17C.
THEREFORE BELIEVE HIGH TEMPS WILL WARM INTO THE UPPER 80S TO LOW
90S. COOLER CONDITIONS ALONG THE COASTLINE AS SEA BREEZE DEVELOPS
THANKS TO WEAK WINDS ALOFT.

BELIEVE THE REGION WILL REMAIN RAIN FREE TOMORROW. HOWEVER CANNOT
RULE OUT THE POTENTIAL FOR A POP-UP SHOWER ALONG THE SEA BREEZE
CONVERGENCE. KEPT THE FORECAST DRY FOR NOW...WILL LET NEXT SHIFT TAKE
A CLOSER LOOK.

&&

.LONG TERM /SUNDAY NIGHT THROUGH SATURDAY/...
HIGHLIGHTS...

* PERIODS OF HOT AND HUMID CONDITIONS FOR A GOOD PORTION OF NEXT WEEK
* MAY SEE WIDELY SCATTERED AFTERNOON/EVENING SHOWERS/THUNDERSTORMS
  MONDAY AFTERNOON THROUGH WEDNESDAY
* ANOTHER STRONGER FRONT MAY BEGIN TO APPROACH LATE NEXT WEEK

OVERVIEW...
LATEST GUIDANCE SUITE REMAINS IN DECENT OVERALL AGREEMENT INTO
THE MIDDLE OF NEXT WEEK. AFTER WEDNESDAY THOUGH...SIGNIFICANT
TIMING DIFFERENCES ARISE...WHICH IN TURN LEADS TO A LOWER
CONFIDENCE FORECAST WITH RESPECT TO TIMING. FOLLOWED A CONSENSUS
SOLUTION TO SMOOTH OVER SOME OF THESE DIFFERENCES. HAVE HIGH
CONFIDENCE IN THE OVERALL TRENDS.

NOT MUCH CHANGE TO THE OVERALL SYNOPTIC PATTERN THROUGH MUCH OF
NEXT WEEK. LOTS OF HEAT AND HUMIDITY AS AN AMPLIFIED MID LEVEL
TROUGH DEVELOPS OVER THE CENTRAL USA...LEAVING OUR REGION BENEATH
A PERSISTENT RIDGE. AT THE SURFACE...A BERMUDA HIGH SHOULD DEVELOP
AND ENHANCE THE FLOW OF HEAT AND HUMIDITY INTO OUR REGION.

THE HEAT AND HUMIDITY WILL LEAD TO A PERSISTENT PATTERN OF DIURNAL
SHOWERS AND THUNDERSTORMS FOR A GOOD PORTION OF NEXT WEEK. THE
TROUBLE IS...THERE ARE NOT MANY FOCUSING MECHANISMS EXPECTED NEAR
OUR REGION UNTIL LATE NEXT WEEK. IN GENERAL...PLAN FOR THE
POSSIBILITY OF AFTERNOON AND EVENING SHOWERS AND THUNDERSTORMS
EACH DAY...ESPECIALLY ACROSS THE INTERIOR.
