AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE TAUNTON MA
215 PM EDT TUE AUG 18 2015

.SYNOPSIS...
ANOTHER HOT AND HUMID DAY IS ON TAP FOR SOUTHERN NEW ENGLAND WITH
SCATTERED HIT AND MISS AFTERNOON SHOWERS AND THUNDERSTORMS.  ANY
LEFT OVER SHOWERS AND THUNDERSTORMS SHOULD COME TO AN END THIS
EVENING WITH MAINLY DRY WEATHER ON WEDNESDAY...BUT IT WILL REMAIN
HUMID. UNSETTLED WEATHER AHEAD OF AN APPROACHING COLD FRONT WHICH
MAY STALL ACROSS THE REGION OVER THE WEEKEND.

&&

.NEAR TERM /UNTIL 6 PM THIS EVENING/...
***HOT AND HUMID TODAY WITH SCATTERED HIT AND MISS SHOWERS/
  THUNDERSTORMS THIS AFTERNOON WITH LOCALLY HEAVY RAINFALL***

2 PM UPDATE...RADAR SHOWS ISOLATED-SCATTERED VERY SLOW MOVING
SHOWERS/T-STORMS. QUITE A FEW HAVE FORMED OVER THE EAST SLOPES OF
THE BERKSHIRES INTO WESTERN HARTFORD COUNTY...WITH ISOLATED CELLS
ELSEWHERE IN THE CWA. BECAUSE OF THE SLOW MOVEMENT THERE IS THE
POSSIBILITY OF LOCALLY HEAVY RAINFALL PRODUCING VERY LOCALIZED
STREET OR OTHER POOR DRAINAGE FLOODING...ESPECIALLY IF ANY SLOW
MOVING STORMS MOVE OVER AN URBANIZED AREA.

EARLY MORNING DISCUSSION FOLLOWS...

OTHER THAN AN ISOLATED SHOWER/THUNDERSTORM OR TWO EARLY THIS MORNING
ACROSS THE FAR SOUTHEAST NEW ENGLAND COAST...MAINLY DRY WEATHER
SHOULD PREVAIL FOR MUCH OF THE MORNING HOURS.  PATCHY GROUND FOG IN
THE TYPICALLY PRONE LOCATIONS WILL QUICKLY BURN OFF AFTER SUNRISE.

BY AFTERNOON...A WEAK SHORTWAVE WILL APPROACH FROM THE SOUTH.
DESPITE POOR MID LEVEL LAPSE RATES...MLCAPE VALUES WILL PROBABLY
REACH AT LEAST 1500 J/KG...AS PARTIAL SUNSHINE ALLOWS HIGHS TO REACH
INTO THE UPPER 80S AND LOWER 90S WITH DEWPOINTS BETWEEN 65 AND 70.
IT WILL BE A FEW DEGREES COOLER ACROSS THE CAPE/ISLANDS...BUT IT
STILL WILL BE HUMID.

THE RESULT OF THE WEAK SHORTWAVE/INSTABILITY WILL BE SCATTERED HIT
AND MISS SHOWERS/THUNDERSTORMS DEVELOPING BY AFTERNOON.  WHILE THE
ACTIVITY MAY AFFECT ANYWHERE ACROSS SOUTHERN NEW ENGLAND...ELEVATED
AREAS SUCH AS EAST SLOPES OF THE BERKS/WORCESTER HILLS AS WELL
LOCATIONS NEAR THE SEA BREEZE FRONT ACROSS EASTERN MA/RI WILL HAVE
SOMEWHAT OF A HIGHER RISK.

WIND FIELDS ARE EXTREMELY WEAK THIS AFTERNOON WITH 0 TO 6 KM SHEAR
VALUES GENERALLY UNDER 10 KNOTS.  THIS COMBINED WITH POOR MID LEVEL
LAPSE RATES WILL KEEP THE OVERALL SEVERE WEATHER POTENTIAL QUITE
LOW.  STILL CAN NOT RULE OUT AN ISOLATED STRONG THUNDERSTORM OR TWO
WITH GUSTY WINDS GIVEN DOWNDRAFT CAPE VALUES APPROACHING 1000 J/KG
AND STEEP LOW LEVEL LAPSE RATES.  HOWEVER...THE MAIN CONCERN WILL BE
ANY STORMS THAT DEVELOP WILL BE SLOW MOVING AND CONTAIN HEAVY
RAINFALL.  THIS WILL BRING THE POTENTIAL FOR VERY LOCALIZED STREET
FLOODING...ESPECIALLY IF ANY SLOW MOVING STORMS MOVE OVER AN
URBANIZED AREA.

&&

.SHORT TERM /6 PM THIS EVENING THROUGH 6 PM WEDNESDAY/...
TONIGHT...

ANY LEFT OVER SCATTERED SHOWERS AND THUNDERSTORMS SHOULD DISSIPATE
THIS EVENING...WITH THE LOSS OF DAYTIME HEATING AND LIMITED SYNOPTIC
FORCING.  THE MAIN CONCERN WILL BE FOR AREAS OF LOW CLOUDS AND FOG
THAT WILL LIKELY SPREAD NORTHWARD ACROSS MUCH OF THE REGION
OVERNIGHT.  AREAL COVERAGE AND EXTENT OF THE LOW CLOUDS AND FOG ARE
STILL UNCERTAIN...SO LATER SHIFTS WILL HAVE TO KEEP A CLOSE EYE ON
THIS POTENTIAL.  LOW TEMPS WILL BE IN THE UPPER 60S TO LOWER 70S AND
IT AGAIN WILL BE MUGGY.

WEDNESDAY...

LOW CLOUDS AND FOG PATCHES MAY AFFECT PORTIONS OF THE REGION DURING
THE MORNING HOURS.  AGAIN...AREAL EXTENT STILL UNCERTAIN BUT SHOULD
SEE SKIES BECOME PARTLY TO MOSTLY SUNNY BY LATE MORNING/EARLY
AFTERNOON.  MOISTURE NOT NEARLY AS DEEP AS TODAY...SO MAINLY DRY
WEATHER ANTICIPATED.  HOWEVER...A SPOT SHOWER OR TWO STILL POSSIBLE
ACROSS OUR WESTERN ZONES SO WILL CARRY SLIGHT CHANCE POPS.
SOUTHERLY FLOW WILL KEEP HIGH TEMPS A FEW DEGREES LOWER THEN THIS
AFTERNOON.  HIGH TEMPS WILL MAINLY BE IN THE MIDDLE TO UPPER 80S BUT
IT WILL BE RATHER HUMID.

&&

.LONG TERM /WEDNESDAY NIGHT THROUGH MONDAY/...
HIGHLIGHTS...
* WARM AND MUGGY CONDITIONS PERSIST THROUGHOUT THE WEEK
* SHOWERS AND THUNDERSTORMS POSSIBLE WITH WEAK FRONT THU AND FRI
* UNSETTLED WEATHER CONTINUES AS FRONT STALLS ACROSS SNE

MODELS ARE IN GOOD AGREEMENT THROUGH THE LONG TERM PORTION OF THE
FORECAST.  AN UPPER LEVEL RIDGE JUST OFFSHORE KEEPS SOUTHERN NEW
ENGLAND IN WARM...MUGGY...SOUTHWESTERLY FLOW.  A WEAK COLD FRONT
WILL MOVE INTO SOUTHERN NEW ENGLAND FRIDAY...STALLING OVER THE
REGION AND PROVIDING A FORCING MECHANISM FOR SHOWERS AND
THUNDERSTORMS THROUGH THE WEEKEND.

WEDNESDAY NIGHT INTO THURSDAY...SHOWERS ARE POSSIBLE ACROSS THE
NORTHWESTERN PORTIONS OF SOUTHERN NEW ENGLAND.  TEMPERATURES DROP A
FEW DEGREES...BUT HUMID CONDITIONS CONTINUE.

FRIDAY THROUGH SUNDAY...A WEAK COLD FRONT MOVES SOUTH INTO SOUTHERN
NEW ENGLAND FRIDAY...STALLING ACROSS THE AREA THROUGH THE WEEKEND.
THIS WILL BE THE FOCUS FOR SHOWERS AND THUNDERSTORMS WITH THE MAIN
THREATS BEING HEAVY RAIN AND LIGHTNING.  WITH PRECIPITABLE WATER
VALUES RUNNING NEAR OR ABOVE 2 INCHES DURING THIS TIME...URBAN AND
POOR DRAINAGE FLOODING IS A STRONG POSSIBILITY. HOWEVER...WEAK WINDS
THROUGH THE COLUMN AND POOR MID LEVEL LAPSE RATES INDICATE THAT
SEVERE WINDS OR HAIL ARE UNLIKELY.

MONDAY...THE GFS INDICATES THE FRONT WASHES OUT BY MONDAY WITH DRY
WEATHER EXPECTED.  THE ECMWF KEEPS THE FRONT OVER SOUTHERN NEW
ENGLAND WITH SHOWERS AND THUNDERSTORMS EXPECTED TO CONTINUE.

&&

.AVIATION /18Z TUESDAY THROUGH SUNDAY/...
FORECASTER CONFIDENCE LEVELS...

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

SHORT TERM /TODAY THROUGH WEDNESDAY/...

CONDITIONS BUT SCATTERED SHOWERS/THUNDERSTORMS THIS AFTERNOON WILL
RESULT IN LOCALIZED LOWER CIGS/VSBYS. ACTIVITY WILL BE HIT AND
MISS AND MOVEMENT OF ANY SHOWERS T-STORMS WILL BE SLOW. MANY
LOCATIONS WILL REMAIN DRY.

TONIGHT...MODERATE CONFIDENCE.  ANY LEFT OVER SCATTERED
SHOWERS/THUNDERSTORMS SHOULD DISSIPATE THIS EVENING.
OTHERWISE...LOW CLOUDS AND FOG PATCHES SHOULD DEVELOP ACROSS THE
SOUTH COAST/CAPE AND ISLANDS THIS EVENING.  THESE LOW CLOUDS/FOG
PATCHES SHOULD ADVANCE FURTHER NORTH AND WEST...PROBABLY AFFECTING
MUCH OF THE REGION BY DAYBREAK TUE BUT STILL UNCERTAINTY ON AREAL
COVERAGE AND TIMING.

WEDNESDAY...MODERATE TO HIGH CONFIDENCE.  LOW CLOUDS AND FOG PATCHES
EXPECTED INTO AT LEAST MID TO LATE MORNING.  SHOULD SEE THEM BURN
OFF ACROSS MOST LOCATIONS BY LATE MORNING/EARLY AFTERNOON WITH VFR

SEA BREEZE TO LAST INTO MID AFTERNOON. SEA BREEZE SHOULD
DISSIPATE BY LATE AFTERNOON OR EARLY EVENING.
