AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE TAUNTON MA
222 PM EDT WED AUG 6 2014

.SYNOPSIS...
*** HIGH RIP CURRENT RISK FOR SOUTH ATLANTIC FACING BEACHES ***

THOUGH POST TROPICAL STORM BERTHA HAS MOVED OUT TO SEA...SOUTH TO
SOUTHEAST SWELLS AND A HIGH RISK OF RIP CURRENTS WILL CONTINUE
INTO THIS EVENING FOR SOUTH AND SOUTHEAST FACING BEACHES. PERIODS
OF SHOWERS AND THUNDERSTORMS CONTINUE THROUGH THURSDAY AS AN
UPPER TROUGH LINGERS ACROSS THE REGION. A SPOT SHOWER IS POSSIBLE
FRIDAY...FOLLOWED BY HIGH PRESSURE WHICH WILL DOMINATE FOR THE
WEEKEND AND EARLY NEXT WEEK.

&&

.NEAR TERM /UNTIL 6 PM THIS EVENING/...
150 PM UPDATE...
BROKEN LINE OF SHOWERS HAS DEVELOPED PRETTY MUCH ALONG I-90 /MASS
PIKE/ IN S CENTRAL MA TO NEAR BOSTON...AS WELL AS MORE PATCHY
SHOWERS THAT HAS DEVELOPED ACROSS E RI/SE INTERIOR MA EARLY THIS
AFTERNOON. THIS IS ALONG A WEAK CONVERGENCE BOUNDARY THAT HAS
MOVED INTO THE REGION...INTERACTING WITH LEFTOVER FRONT NEAR OR
JUST OFF THE S COAST. WILL SEE BRIEF LOCALLY HEAVY RAINFALL WITH
SOME OF THESE SHOWERS. APPEARS THESE ARE REMAINING JUST BELOW
LIGHTNING LEVEL FOR NOW /AROUND 16KFT OR SO/...BUT COULD STILL SEE
SOME THUNDERSTORMS DEVELOP LATER THIS AFTERNOON SO HAVE KEPT
MENTION IN. FOR MOST OTHER AREAS...PATCHY DIURNAL CLOUDS HAVE
DEVELOPED BUT LOOKS LIKE SHOULD REMAIN MAINLY DRY...THOUGH CAN NOT
RULE OUT A FEW LIGHTER SHOWERS THAT MAY DEVELOP THROUGH LATE
AFTERNOON.

TEMPS IN A FEW SPOTS INLAND HAVE REACHED OR JUST SURPASSED 80
DEGREES...OTHERWISE TEMPS MAINLY IN THE 70S AT 17Z. NOTING LIGHT
WINDS HAVE SHIFTED TO W-SW ALONG PORTIONS OF THE S COAST WITH NW
JUST INLAND...ALONG WITH HIGHER DEWPTS ACROSS RI/SE MA. SEA BREEZE
HAS FINALLY KICKED IN KBOS AND POINTS S...THOUGH MAINLY 10 KT OR
LESS.

HAVE UPDATED GRIDS TO REFLECT CURRENT CONDITIONS.

PREVIOUS DISCUSSION...
AREA OF DEEP LAYER ASCENT COUPLING WITH SURFACE SEA BREEZE
CONVERGENCE BOUNDARIES YIELDING ISOLATED TO SCATTERED SHOWERS AND
THUNDERSTORMS AS THE WARM AND MUGGY ENVIRONMENT /HIGHS AROUND 80
WITH DEWPOINTS AROUND THE LOW TO MID 60S/ DESTABILIZES WITH CAPE
VALUES OF AROUND 1000 J/KG. GREATEST CONFIDENCE REMAINS ACROSS
INTERIOR E/SE MA AND RI AS SEEN ON LATEST SHORT RANGE MODELS.

BEST UNIDIRECTIONAL W-E SHEAR OF 30 TO 40 KTS IS ALSO SEEN ACROSS
CT/RI/SE MA ON LATEST SPC MESOANALYSIS. COULD STILL SEE SOME
STRONG...GUSTY WINDS WITH INVERTED-V BOUNDARY LAYER PROFILES.
LIMITING FACTOR WILL BE VERTICAL EXTENT OF CONVECTION. SMALL HAIL
IS ALSO POSSIBLE...ESPECIALLY WITH ANY ROTATING UPDRAFTS THAT ARE
ABLE TO LOFT PRECIPITATION ABOVE 12 KFT FREEZING LEVEL HEIGHTS FOR
LONGER PERIODS OF TIME.

ALSO...CONSIDERING 0-6 KM W-E MEAN WIND OF 20 KTS....AND PWATS UP
TO 1.5 INCHES...THERE IS ALSO THE THREAT OF HEAVY DOWNPOURS
YIELDING LOCALIZED URBAN AND SMALL STREAM FLOODING. THIS CAN ALSO
BE THE CASE IF STORMS MAINTAIN ALONG SEA BREEZE BOUNDARIES.

&&

.SHORT TERM /6 PM THIS EVENING THROUGH 6 PM THURSDAY/...
TONIGHT...
ACTIVITY DISSIPATING DURING THE EVENING HOURS. EXPECTING SHOWERS
AND THUNDERSTORMS TO CONCLUDE AROUND 10 PM...REMAINING QUIET
OVERNIGHT. THOUGH MID-LEVEL TROUGH HOLDS ACROSS THE REGION...A
PERIOD OF STRONG SUBSIDENCE IN WAKE OF THE MID-LEVEL ENERGY DURING
THE DAY ALLOWS FOR CLEARING CONDITIONS AND PUSH OF DRIER AIR BY
N/NW WINDS AT THE SURFACE. LESSER CONCERN WITH DENSE FOG OTHER
THAN POSSIBLY ALONG THE S/SE COASTLINE AND ADJACENT WATERS.

THURSDAY...
THROUGH THE PREVAILING MID LEVEL TROUGH...A SECONDARY MID LEVEL
IMPULSE USHERS BOTH ENHANCED ASCENT AND COOLER AIR ACROSS THE
REGION. H5 TEMPERATURES BOTTOMING OUT TO -18C TOWARDS AFTERNOON
ALLOWS FOR STEEP LAPSE RATES AND LOWER FREEZING LEVEL HEIGHTS
DOWN TO AROUND 9 KFT.

A CLASSIC SET UP TOWARDS THE DEVELOPMENT OF SCATTERED SHOWERS AND
THUNDERSTORMS WITH THE EMBEDDED THREATS OF HAIL /THIN CAPE
PROFILES BEYOND -20C/ AND GUSTY WINDS /INVERTED V BOUNDARY LAYER
SOUNDINGS/. SOME OF THE STORMS MAY BE SLOW MOVERS WITHIN THE 0-6
KM MEAN WIND ENVIRONMENT ROUGHLY AROUND 15 KTS /20 MPH/...SO
THOUGH PWATS WILL RANGE AS HIGH AS 1 INCH /CONSIDERABLY DRY/
THERE IS THE THREAT OF HEAVY DOWNPOURS AND LOCALIZED FLOODING WITH
ANY SLOW MOVING STORMS.

MUCH OF THE ACTIVITY IS ANTICIPATED ACROSS THE INTERIOR AWAY FROM
THE IMMEDIATE SHORES AS SEA BREEZES ARE LIKELY TO DEVELOP TOWARDS
MIDDAY. SEASONABLE CONDITIONS WITH HIGHS AROUND THE UPPER 70S.

&&

.LONG TERM /THURSDAY NIGHT THROUGH TUESDAY/...
OVERVIEW AND MODEL PREFERENCES...

NOT TOO MUCH CHANGE IN THE FORECAST BASED ON LATEST GUIDANCE
UPDATES. THE BEGINNING OF THE MID-LONG TERM WILL FEATURE A SLOW
MOVING TROF ACROSS THE NORTHEAST WITH HEIGHTS ABOUT 3 STD
DEVIATIONS BELOW NORMAL. AFTER FRIDAY...A FAIRLY ROBUST NRN CONUS
RIDGE WILL BEGIN TO BUILD IN FROM THE GREAT LAKES REGION. THIS
RIDGE LOOKS TO BUILD IN PLACE FOR SOME TIME...AS CANADIAN PRAIRIE
TROF CONTINUES TO DEEPEN TO ITS W. THEREFORE...AFTER AN UNSTABLE
START FOR FRI...LOOKS LIKE A PERIOD OF DRY WX WITH GRADUALLY
MODERATING TEMPERATURES ARE EXPECTED INTO EARLY NEXT WEEK. ITS NOT
UNTIL THIS SECOND WAVE ASSOCIATED WITH BAFFIN ISLAND CUTOFF LOW
PRES...ALLOWS FOR SOME MORE UNSETTLED AND POTENTIALLY WET WX FOR
THE MIDDLE PORTIONS OF NEXT WEEK. WITH FAIR AGREEMENT BETWEEN
06.00Z MODEL GUIDANCE...A CONSENSUS BLEND WILL BE USED AS A
BASELINE.

DETAILS...

THU NIGHT INTO FRI...ANOMALOUSLY DEEP TROF WITH H5 HEIGHTS 3 STD
DEVIATIONS FROM NORMAL WILL BE SLOWLY EXITING TO THE E THROUGH
THIS PERIOD. THE ROBUST ACUITY OF THIS TROF SUGGESTS STRONG
CYCLONIC CURVATURE WITH H5 TEMPS DIPPING TO NEAR -18C...WARMING
CLOSER TO - 12C BY LATE DAY FRI. THEREFORE...ANY CONVECTIVE
ACTIVITY MAY LINGER INTO THE EVENING HOURS THU...ALTHOUGH DIURNAL
HEATING LOSS WILL STABILIZE THINGS SOMEWHAT. BY FRI...GIVEN THE
CURVATURE AND MODEST COLUMN MOISTURE...MAY SEE ANOTHER ROUND OF
DIURNAL SHOWERS...BUT FEEL THEY ARE LIKELY TO BE LESS ROBUST AND
FEW AND FARTHER BETWEEN AS THE TROF PULLS E ALONG WITH SOME OF THE
MOISTURE...AND THE MID LVL WARMING DIMINISHES THE AFTERNOON
DESTABILIZATION. HOWEVER...A FAIR AMOUNT OF DIURNAL CLOUD COVER IS
EXPECTED AGAIN AT THE LEAST. H85 TEMPS WARM THROUGH FRI...TO ABOUT
+10C...SO WITH FULL MIXING TEMPS COULD APPROACH SEASONABLE
NORMALS...HOWEVER...THE CLOUD COVER MAY KEEP TEMPS BACK A BIT TO
SOMEWHAT BELOW NORMAL...MAINLY THE UPPER 70S.

SAT THROUGH MON...ROBUST MID LVL RIDGE WILL BE ALLOWING SFC HIGH
PRES TO MOVE THROUGH THE REGION DURING THIS PERIOD. EXPECT MAINLY
DRY WX WITH GRADUALLY INCREASING TEMPS. H85 TEMPS START SAT AROUND
+10C...THEN INCREASE TO ABOUT +14C ON MON. HIGHS THEN START SAT IN
THE LOW 80S...THEN INCREASE TO MID-UPPER 80S IN SPOTS ON MON.
DWPTS ARE MAINLY IN THE MID 50S TO LOW 60S SO EXPECT LOWS TO LINE
UP TO THIS AS WELL. WEAK PRES GRADIENTS SUGGEST SEA BREEZES EACH
DAY...SO NEAR SHORE TEMPS ARE LIKELY COOLER.

TUE INTO WED...UPPER LVL RIDGE GIVES WAY TO A FAIRLY ROBUST TROF
THROUGH THE PERIOD. THERE ARE SOME TIMING DIFFERENCES...BUT GIVEN
THE AMPLIFIED PATTERN...WILL ADD A BIT MORE WEIGHT TO THE SLOWER
ECMWF. THEREFORE...TUE LIKELY REMAINS MOSTLY DRY BUT WITH
INCREASING TEMPS/DWPTS. BY WED...A COLD FRONT LOOKS TO CROSS THE
REGION...BRINGING ABOUT UNSETTLED CONDITIONS WITH THE POTENTIAL
FOR SHOWERS AND THUNDERSTORMS.
