AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE TAUNTON MA
206 PM EDT SAT JUL 20 2013

.SYNOPSIS...
ONE MORE HOT AND HUMID DAY IS EXPECTED TODAY ALONG WITH SCATTERED
STRONG TO SEVERE THUNDERSTORMS THIS AFTERNOON AS A COLD FRONT
APPROACHES FROM THE GREAT LAKES. THIS FRONT WILL BRING RELIEF FROM
THE EXCESSIVE HEAT AND HUMIDITY ON SUNDAY. MORE SEASONABLE BUT
HUMID CONDITIONS ARE EXPECTED FOR MUCH OF NEXT WEEK WITH
SCATTERED SHOWERS AND THUNDERSTORMS FROM TIME TO TIME.

&&

.NEAR TERM /UNTIL 6 PM THIS EVENING/...
150 PM UPDATE...
HIGH CLOUDS HAVE MOVED IN...BUT DID HAVE SEVERAL HOURS OF MAINLY
CLEAR SKIES WHICH HAS ALLOWED FOR VERY GOOD HEATING AS TEMPS HAVE
RISEN TO THE LOWER-MID 90S FOR MOST INLAND AREAS. WITH THE HIGH
DEWPTS ALSO IN PLACE...ESPECIALLY IN THOSE AREAS NEAR AND S OF THE
MASS PIKE IN THE LOWER-MID 70S...HAS ALLOWED FOR QUICKLY
INCREASING INSTABILITY. LOW LEVEL LAPSE RATES ARE RATHER HIGH
ACROSS CENTRAL AND EASTERN AREAS...ON ORDER OF 8-8.5 C/KM. ALSO
NOTING INCREASING SHEAR /W-SW AT 30-35 KT/ ACROSS CENTRAL AND
NORTHERN AREAS WHICH WILL SHIFT S AS THE FRONT MOVES SE.

CONVECTION ALREADY STARTING TO KICK OFF...AND EVEN HAD A CELL
DEVELOP S OFF CAPE ANN EARLIER. WITH THE QUICKLY DESTABILIZING
AIRMASS OVER THE REGION...SPC HAS ALREADY ISSUED MESOSCALE
DISCUSSION WITH LIKELIHOOD OF WATCH COMING OUT SHORTLY.

HAVE UPDATED GRIDS TO BRING CONDITIONS CURRENT...BUT NOTING RAPID
CHANGES TO RADAR COVERAGE AT 2 PM.

&&

.SHORT TERM /6 PM THIS EVENING THROUGH 6 PM SUNDAY/...
TONIGHT...
SCT SHOWERS AND TSTMS MAY LINGER ACROSS THE COASTAL PLAIN AND S
COAST INTO THE EVENING BEFORE ACTIVITY DISSIPATES AND MOVES
OFFSHORE. COLD FRONT WILL MOVE S ACROSS THE REGION TONIGHT BUT
NOT CLEARING THE S COAST UNTIL CLOSER TO 12Z SUN.

SUNDAY...
WEAK FRONT WILL STALL S OF NEW ENG WITH WEAK HIGH PRES BUILDING
TO THE N. WHILE IT WILL BE NOTICEABLY COOLER...850 MB TEMPS 14-16C
SO IT WILL STILL BE RATHER WARM WITH TEMPS IN THE MID TO UPPER
80S...COOLER HIGHER TERRAIN AS WELL AS IMMEDIATE COAST WHERE
COASTAL SEABREEZES ARE LIKELY. DEWPOINTS MAY DROP INTO THE UPPER
50S ACROSS N ZONES...BUT LIKELY REMAIN IN THE MID 60S CLOSER TO
THE COAST. LOW RISK FOR AN ISOLD SHOWER SUN AFTERNOON...OTHERWISE
DRY WEATHER WITH PT-MOSUNNY SKIES.

&&

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

HEADLINES...

* SCT SHOWERS/THUNDERSTORMS MON NIGHT THROUGH FRI BUT NOT A WASHOUT
* SEASONABLE TEMPS AND NO EXCESSIVE HEAT EXPECTED NEXT WEEK

DETAILS...

SUNDAY NIGHT AND MONDAY...
HIGH PRESSURE NEARBY SHOULD RESULT IN DRY WEATHER DOMINATING OVER
THIS TIME. STILL CAN/T RULE OUT A FEW SPOT SHOWERS ACROSS THE
INTERIOR/SOUTH COAST AS MID LEVEL MOISTURE WILL BE NEARBY...ALONG
WITH WEAK SURFACE CONVERGENCE. WILL COVER THIS REGION WITH JUST
SOME LOW POPS. TEMPS WILL BE SEASONABLE WITH LOWS IN THE UPPER 50S
AND 60S SUN NIGHT. HIGHS ON MON SHOULD BE MAINLY IN THE LOWER TO
MIDDLE 80S.

MONDAY NIGHT AND TUESDAY...
UPPER LEVEL TROUGH DEVELOPING ACROSS THE
GREAT LAKES WILL SEND A COUPLE OF SHORTWAVES AT US IN WEST TO
SOUTHWEST FLOW ALOFT.  APPEARS THERE SHOULD BE ONE OR TWO ROUNDS OF
SCATTERED SHOWERS AND THUNDERSTORMS SOMETIME MON NIGHT INTO TUE.
HIGH PWATS WILL RESULT IN THE POTENTIAL FOR HEAVY RAINFALL AND A
VERY LOCALIZED FLOOD THREAT WITH ANY STORM.  OVERALL SEVERE WEATHER
POTENTIAL WILL BE LOW GIVEN LIMITED INSTABILITY AS WELL AS
UNCERTAINTY ON THE AMOUNT OF SOLAR INSOLATION.

***NO CHANGES MADE BEYOND TUESDAY BASED ON CURRENT WEATHER BUT HERE
  ARE OUR LATEST THOUGHTS***

AS FOR TEMPERATURES...NOT EXPECTING A RETURN TO THE EXCESSIVE HEAT
WITH THE RIDGE OVER THE ATLANTIC TOO FAR EAST.  HOWEVER...HIGHS
SHOULD STILL BE IN THE 80S ALONG WITH SOME HUMIDITY AT TIMES.

WEDNESDAY THROUGH FRIDAY... A LOT OF UNCERTAINTY OVER THIS TIME
PERIOD.  THE GFS DRIES OUT BY THURSDAY AS THE UPPER LEVEL TROUGH
BECOMES FLATTER AND PUSHES THE MAIN FRONT WELL OFFSHORE.
HOWEVER...THE ECMWF IS MORE AMPLIFIED WITH THE TROUGH OVER THE
EASTERN GREAT LAKES AND UPPER RIDGE OVER THE ATLANTIC.  THIS KEEPS
THE FRONTAL BOUNDARY NEARBY ALONG WITH SOUTHWEST FLOW ALOFT. HIGHLY
UNCERTAIN AT THIS POINT...BUT AT LEAST WORTH MAINTAINING SOME CHANCE
POPS FOR ADDITIONAL SCATTERED SHOWERS AND THUNDERSTORMS.
AGAIN...NOT EXPECTING A WASHOUT BUT CERTAINLY THE POTENTIAL FOR
ADDITIONAL PRECIPITATION.

SATURDAY...
LOW CONFIDENCE THIS FAR OUT BUT FRONT MAY BE FAR ENOUGH
OFFSHORE TO RESULT IN DRY WEATHER WITH SEASONABLE TEMPS.

&&

.AVIATION /18Z SATURDAY THROUGH FRIDAY/...

FORECASTER CONFIDENCE LEVELS...

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

ELSEWHERE EXCEPT LOCAL MVFR-IFR CIGS/VSBYS IN SHRA/TSRA. WILL SEE
INCREASING COVERAGE THROUGH THE AFTERNOON.

WITH ANY TSRA...LOW-VFR CIGS WITH MVFR/IFR VSBYS WILL BE
POSSIBLE. UNCERTAINTY ON LOCATION AND EVOLUTION OF TSRA SO DID NOT
PREVAIL IN THE TAF. GUSTY SW WINDS AHEAD OF AN APPROACHING COLD
FRONT ANTICIPATED TO SWEEP THROUGH THE TERMINALS LATE TONIGHT INTO
SUNDAY MORNING...WINDS BACKING OUT OF THE NORTH-NORTHWEST AND
WEAKENING.

COASTAL FOG MAY DEVELOP AHEAD OF THE COLD FRONT. SHOULD SEE
IMPROVEMENT THEREAFTER WITH DRIER AIR FILTERING IN. PREVAILING
VFR FOR SUNDAY WITH LIGHT NORTH-NORTHWEST WINDS...SEA-BREEZES
ALONG THE SHORES.

KBOS TERMINAL...MODERATE CONFIDENCE IN TAF. WILL KEEP STORMS OUT
OF THE TERMINAL FOR NOW. GUSTY SOUTHWEST WINDS DURING THE DAY.

CONDITIONS DOMINATE. MAY SEE SOME LOCALIZED LOWER CONDITIONS IN
LATE NIGHT/EARLY MORNING LOW CLOUDS/FOG PATCHES.

TUESDAY THROUGH THURSDAY...MODERATE CONFIDENCE. VFR CONDITIONS

BELOW SCA THRESHOLDS.

OUTLOOK...SUNDAY NIGHT INTO THURSDAY...

SUNDAY NIGHT INTO MONDAY...HIGH CONFIDENCE.

HIGH PRESSURE IN CONTROL. LIGHT AND VARIABLE WINDS GRADUALLY
BACKING OUT OF THE SOUTH. SEAS BELOW 5 FEET OVER ALL WATERS.

MONDAY NIGHT INTO WEDNESDAY...MODERATE CONFIDENCE.

INCREASE AREAL COVERAGE OF SHOWERS AND THUNDERSTORMS. WINDS OUT OF
THE SOUTH-SOUTHWEST INCREASING. GUSTS UP TO 20 KTS POSSIBLE. FETCH
RESULTING IN SEAS BUILDING ABOVE 5 FEET OVER THE SOUTH-SOUTHEAST
WATERS. COLD FRONT SLIDES INTO THE WATERS WEDNESDAY ALLOWING WINDS

VISIBILITIES DOWN TO A QUARTER MILE OR LESS.

THURSDAY...MODERATE CONFIDENCE.

COLD FRONT WAVERS AS IT STALLS IN PROXIMITY TO SOUTHERN NEW ENGLAND.
