AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE TAUNTON MA
1032 PM EDT FRI AUG 23 2013

.SYNOPSIS...

COOLER AND DRIER CONDITIONS WILL PERSIST THROUGH THE WEEKEND. BUT
AN UNSETTLED WEATHER PATTERN SETS UP FOR MUCH OF NEXT WEEK WITH
AN INCREASING THREAT OF SHOWERS AND THUNDERSTORMS.

&&

.NEAR TERM /UNTIL 6 AM SATURDAY MORNING/...

1030 PM UPDATE...

HAVE REMOVED THE MENTION OF ANY SPRINKLES. EVALUATING THE 0Z
CHATHAM SOUNDING...THE COLUMN IS IMPRESSIVELY DRY WITH A PWAT
VALUE OF 0.72 INCHES. WHILE THE MID-LEVEL AXIS AND ATTENDANT
VORTMAX IS APPARENT PER WATER VAPOR IMAGERY...THE AMOUNT OF
ENHANCED ASCENT OF AVAILABLE MOISTURE SHOULD YIELD LITTLE IF
ANYTHING. AT MOST...SCATTERED TO BROKEN CLOUD DECKS OF 5-7 KFT.
TROUGH SHOULD BE OFFSHORE BY MORNING BEHIND WHICH WINDS WILL TURN
MORE NORTHERLY PUSHING COOLER AND DRIER AIR SOUTH OUT OF CANADA.

OTHERWISE MINOR TWEAKS TO TEMPERATURES...DEWPOINTS...AND SKY
CONDITIONS TO ACCOUNT FOR TRENDS. LOWS ON TRACK FOR THE MID-50S
ACROSS THE INTERIOR WITH UPPER-40S FOR THE HIGHER TERRAIN.
REMAINING MILD ALONG THE IMMEDIATE COAST. LOWER CONFIDENCE OF
PATCHY FOG ACROSS THE INTERIOR SHELTERED VALLEYS. IF ANY...VERY
LOCALIZED TO SHALLOW AREAS NEAR BODIES OF WATER.

&&

.SHORT TERM /6 AM SATURDAY MORNING THROUGH SATURDAY NIGHT/...

SATURDAY AND SATURDAY NIGHT...

SURFACE HIGH PRESSURE WILL BUILD INTO THE REGION SATURDAY AND
LINGERING INTO SATURDAY NIGHT. 850MB TEMPS WILL BE AROUND 10C
TOMORROW AND WITH FULL MIXING EXPECT...TEMPERATURES WILL WARM INTO
THE UPPER 70S. A GOOD AMOUNT OF SUBSTANCE BEHIND THE TROUGH WILL
KEEP DEWPOINTS LOW. NORTHERLY WINDS WILL BE AROUND 10KTS WITH HIGHER
GUSTS ALONG THE EAST COAST/CAPE AND ISLANDS. EAST COASTAL REGIONS
WILL BE COOLER AS SEA BREEZE DEVELOPS AND PUSHES INLAND.

OVERNIGHT WILL REMAIN QUIET. MAIN CONCERN WILL BE HOW LOW
TEMPERATURES WILL GET. WITH HIGH PRESSURE OVER THE AREA WINDS
OVERNIGHT WILL BE LIGHT COMBINED WITH CLEAR SKIES WILL ALLOW FOR
TRUE RADIATIONAL COOLING. AS DEWPOINTS DURING THE DAY WILL REACH IN
THE LOW TO MID 40S...BELIEVE THAT OVERNIGHT TEMPS WILL DROP INTO THE
UPPER TO MID 40S ESPECIALLY ACROSS THE NW ZONES AND TRUE RADIATIONAL
COOLING LOCALES.

&&

.LONG TERM /SUNDAY THROUGH FRIDAY/...

HIGHLIGHTS...
  * QUIET WEATHER AT THE START AND END OF NEXT WEEK
  * UNSETTLED WEATHER FOR THE MIDDLE OF NEXT WEEK

MODELS ARE IN GOOD AGREEMENT FOR MUCH OF THE LONG TERM FORECAST.
THERE ARE DISCREPANCIES BETWEEN THE ECMWF AND THE GFS WITH RESPECT
TO THE SURFACE PATTERN FOR THE MIDDLE OF NEXT WEEK.  HOWEVER...BOTH
MODELS ARE IN GOOD SYNC WITH THE GENERAL SYNOPTIC SCALE PATTERN OF A
MID LEVEL RIDGE OVER THE MIDWEST WITH NORTHWESTERLY FLOW BRINGING A
SERIES OF SHORTWAVES ACROSS SOUTHERN NEW ENGLAND.  LOOKS LIKE A
QUIET START FOR NEXT WEEK...UNSETTLED WEATHER THROUGH THE MIDDLE OF
THE WEEK...AND A RETURN TO QUIETER WEATHER TOWARDS THE END OF THE
WEEK.

SUNDAY...
HIGH PRESSURE SOUTH OF NEW ENGLAND WILL STILL BE IN CONTROL
WITH SEASONABLE TEMPERATURES AND MOSTLY SUNNY SKIES.

MONDAY THROUGH THURSDAY...
A SERIES OF MID LEVEL SHORTWAVES WILL MOVE THROUGH THE
NORTHWESTERLY FLOW OVER SOUTHERN NEW ENGLAND BRINGING A CHANCE OF
SHOWERS AND THUNDERSTORMS TO THE AREA EACH DAY. SEVERAL LOW
PRESSURE SYSTEMS MAY DEVELOP AT THE SURFACE MOVING NEAR TO OR
ACROSS SOUTHERN NEW ENGLAND THOUGH THE MODELS ARE NOT IN AGREEMENT
ON THE TIMING OR TRACKS OF THESE LOW PRESSURE SYSTEMS. FOR THIS
TIME PERIOD WILL STICK MAINLY WITH THE WPC FORECAST WHICH
INCORPORATES BOTH THE GEFS AND ECMWF ENSEMBLE MEANS. WHILE AT
LEAST A CHANCE OF SHOWERS AND THUNDERSTORMS IS EXPECTED EACH
DAY...THERE IS LOW CONFIDENCE ON THE TIMING AND EXTENT OF THESE
SHOWERS AND THUNDERSTORMS. TEMPERATURES LOOK TO BE SEASONABLE BUT
DEWPOINTS AND THUS RELATIVE HUMIDITY VALUES WILL INCREASE.

FRIDAY...
HIGH PRESSURE STARTS TO BUILD BACK INTO THE REGION WITH QUIETER
WEATHER EXPECTED.

&&
