AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE TAUNTON MA
236 AM EDT SAT JUL 23 2011

.SYNOPSIS...
ONE MORE HOT DAY IS AHEAD TODAY BEFORE A COLD FRONT BRINGS RELIEF
WITH MORE SEASONABLE TEMPERATURES SUNDAY AND INTO THE MIDDLE OF
NEXT WEEK. ALTHOUGH DRY WEATHER WILL PREVAIL...THE BEST CHANCE OF
SHOWERS OR THUNDERSTORMS WILL BE LATE MON INTO EARLY TUE IN
ASSOCIATION WITH ANOTHER COLD FRONT.

&&

.NEAR TERM /THROUGH TODAY/...
HIGHS TODAY ARE EXPECTED TO TOP OUT WELL UP INTO 90S IF NOT 100
IN A FEW LOCATIONS. GFS 850 MB TEMPERATURES 20-22C ARE MORE
SUPPORTIVE OF THIS WITH W FLOW...WHILE NAM KEEPS IT SLIGHTLY
COOLER. ONE THING WE ARE CONCERNED WITH IS PRESENCE OF THICKER MID
AND HIGH CLOUDS PUSHING E FROM UPSTATE NY. RIGHT NOW IT LOOKS LIKE
MOST OF THESE WILL TEND TO THIN OUT AS THEY HEAD E...BUT IF NOT WE
WILL ONLY TOP OUT IN 80S AND LOWER 90S.

MEANWHILE...LOWER DEWPOINTS CONTINUE TO PUSH BEYOND S COAST EARLY
THIS MORNING. 70+ DEWPOINTS WILL REMAIN JUST S OF NEW ENGLAND
TODAY BUT WILL TRY TO RETURN TO S COAST...CAPE COD AND ISLANDS
LATER THIS AFTERNOON.

THIS WILL RESULT IN HEAT INDICES NEAR 100 ACROSS N CT...N RI AND
MUCH OF MA. CONFIDENCE IS HIGH ENOUGH TO ISSUE A HEAT ADVISORY FOR
THESE LOCATIONS TODAY.

APPROACHING COLD FRONT MAY BE ABLE TO TRIGGER ISOLATED SHOWERS OR
THUNDERSTORMS LATER TODAY...PRIMARILY ACROSS CT AND PERHAPS INTO
RI AND SE MA WHERE BEST INSTABILITY AND LOW LEVEL CONVERGENCE IS
PROGGED. INTERESTINGLY 21Z/22 SREF SHOW HIGHEST PROBABILITIES THIS
MORNING BUT ASIDE FROM LONE STORM OVER EASTERN NY...ALL OF SHOWERS
ARE LOCATED FARTHER TO N AND DO NOT POSE A THREAT FOR SOUTHERN NEW
ENGLAND.

RIP CURRENT FORECAST...LOW RISK AT BEACHES TODAY. LOOKS MARGINAL
FOR A MODERATE RISK ON S FACING BEACHES OF MARTHAS VINEYARD AND
NANTUCKET DUE TO 4 FT S SWELLS OFFSHORE. LATE MORNING UPDATE MAY
NEED TO UPGRADE RISK FOR THOSE LOCATIONS.

&&

.SHORT TERM /TONIGHT THROUGH 6 PM SUNDAY/...
COLD FRONT WILL CROSS REGION TONIGHT...FOLLOWED BY DRIER NW FLOW.
ISOLATED SHOWERS/STORMS POSSIBLE EARLY OTHERWISE DRY WEATHER
EXPECTED.

FRONT REMAINS S OF NEW ENGLAND SUN WITH SOMEWHAT COOLER AND DRIER
AIR OVER REGION. WEAK GRADIENT WILL SUPPORT AFTERNOON SEA BREEZES.
HOWEVER WITH FRONT NOT TOO FAR AWAY WE MAY SEE ISOLATED SHOWERS/STORMS
NEAR LOWER CT VALLEY AS MODELS SHOW MCS DROPPING SE FROM GREAT
LAKES. GIVEN UNCERTAINTY KEPT FORECAST DRY FOR NOW.

TEMPERATURES ARE A BLEND OF GFS/NAM MOS.

&&

.LONG TERM /SUNDAY NIGHT THROUGH FRIDAY/...
MONDAY-TUESDAY... SHORTWAVE APPROACHES THROUGH THE GREAT LAKES
SUPPORTED BY A 100 KNOT UPPER JET. THIS JET APPROACHES WESTERN NEW
ENGLAND LATE IN THE DAY. MAXIMUM LAPSE RATES REMAIN TO OUR WEST
OVER NEW YORK MOST OF THE DAY. STABILITY INDICES FOCUS MAINLY OVER
NEW YORK...ALTHOUGH THE GFS BRINGS FAVORABLE TOTALS AND LI TO THE
BERKSHIRES AND CT VALLEY STARTING AROUND 18Z MONDAY. WE WILL BRING
LOW-END CHANCE POPS TO THE CT VALLEY AROUND THAT TIME AND
SPREAD...WITH LOW CONFIDENCE...TO EASTERN AREAS TOWARD 21Z. SOME
OF THE GUIDANCE IS INDICATING LIKELY POPS NORTH OF THE MASS
PIKE...BUT WE THINK THIS IS TOO BULLISH GIVEN HOW EQUIVOCAL THE
STABILITY NUMBERS ARE. BEST CHANCE WILL BE MONDAY NIGHT AS THE
SURFACE FRONT MOVES THROUGH AND AS THE DYNAMIC SUPPORT FROM THE
PASSING UPPER JET COMES INTO PLAY.

THE COLD FRONT MOVES EAST ON TUESDAY. THE UPPER SHORTWAVE MOVES
OVERHEAD DURING THE DAY WITH A -14C TO -16C COLD POOL MOVING ACROSS
NEW ENGLAND.  THE COLD POOL AND CYCLONIC FLOW SUGGEST CONVECTION.
STABILITY PARAMETERS ARE ALSO FAVORABLE WITH TOTALS AROUND 50 NORTH
OF THE MASS PIKE...LI/S SUB-ZERO...AND MID LEVEL LAPSE RATES AROUND
6.25C/KM.  WE HAVE INCLUDED CHANCE POPS IN AREAS ALONG AND NORTH OF
THE MASS PIKE.  850 MB TEMPS AROUND 12C SUPPORT MAX TEMPS UPPER 70S
TO LOWER 80S.

WEDNESDAY-THURSDAY...
HIGH PRESSURE BUILDS OVER THE REGION.  FAIR WEATHER AND STABLE
AIRMASS.  TEMPS ALOFT START WARMING...SO MAX TEMPS SHOULD BE A
LITTLE WARMER EACH DAY.  12-14C ON WEDNESDAY AND 14-16C
THURSDAY...SO MAX TEMPS IN THE 80S.  DEWPOINTS WILL CLIMB INTO THE
60S DURING THIS PERIOD.

FRIDAY...
NEXT WEATHER SYSTEM MOVES ACROSS CANADA AND PASSES TO OUR NORTH.
MODELS SHOW A BAND OF CLOUDS MOVING ACROSS NEW ENGLAND THURSDAY
NIGHT AND EARLY FRIDAY...PROBABLY A WARM FRONT OF SORTS.  CERTAINLY
TEMPS ALOFT GET MUCH WARMER WITH 850 TEMPS JUMPING TO 18-20C.  NOT A
LOT OF CONFIDENCE WITH ANY PRECIP WITH THE WARM FRONT SO WE HAVE
LIMITED POPS THURSDAY NIGHT/EARLY FRIDAY TO SLIGHT CHANCE.  TIMING
ON THE COLD FRONT RANGES FROM LATE FRIDAY AFTERNOON TO SATURDAY
MORNING.  FOR NOW WE HAVE INCLUDED SLIGHT CHANCE POPS FRIDAY NIGHT.

&&

.AVIATION /06Z SATURDAY THROUGH WEDNESDAY/...
FORECASTER CONFIDENCE LEVELS...
  LOW...LESS THAN 30 PERCENT
  MODERATE...30 PERCENT TO 60 PERCENT
  HIGH...GREATER THAN 60 PERCENT

HIGH CONFIDENCE IN TAFS WITH VFR THROUGH TAF PERIOD.

EXCEPTION IS AROUND CAPE COD AND ISLANDS WHERE PATCHY FOG WILL
PRODUCE MVFR/IFR THROUGH SUNRISE...THEN AREAS OF HAZE WITH LOCAL
MVFR THROUGH AFTERNOON. SIMILAR SCENARIO TONIGHT WITH MVFR/IFR IN
PATCHY FOG. ALSO HAVE POTENTIAL FOR IFR/LIFR CIGS BUT NOT
CONFIDENT ENOUGH TO INCLUDE IN TAFS.

DEVELOPMENT OF SHRA/TSRA THIS AFTERNOON SEEMS LIMITED...BUT MOST
LIKELY TO OCCUR ACROSS CT AND PERHAPS RI/SE MA AFTER 18Z.

KBOS TERMINAL...HIGH CONFIDENCE IN TAF. NO SEA BREEZE TODAY WITH
INCREASING W WIND /240-270/ LATER THIS MORNING.

OUTLOOK...MONDAY THROUGH WEDNESDAY...

GENERALLY VFR.  AREAS OF IFR/LIFR POSSIBLE IN LATE NIGHT AND EARLY
MORNING FOG.  POTENTIAL FOR MVFR CEILINGS/VSBYS IN SCATTERED
THUNDERSTORMS LATE MONDAY AND MONDAY NIGHT.  MEDIUM CONFIDENCE.

&&

.MARINE...
WINDS AND SEAS EXPECTED TO REMAIN BELOW SCA THROUGH SUN. W WINDS
TODAY SHIFT TO N TONIGHT AS COLD FRONT CROSSES SOUTHERN NEW
ENGLAND. WEAK GRADIENT SUN WILL SUPPORT AFTERNOON SEA BREEZES.

PATCHY MORNING FOG WILL GIVE WAY TO HAZY CONDITIONS ON WATERS THIS
AFTERNOON...ESPECIALLY NEAR S COAST. POTENTIAL FOR ISOLATED
SHOWERS/STORMS LATER TODAY AND THIS EVENING ON S COASTAL
WATERS...MAINLY NEAR BLOCK ISLAND.

OUTLOOK...MONDAY THROUGH WEDNESDAY...

WINDS AND SEAS SHOULD REMAIN BELOW SMALL CRAFT ADVISORY CRITERIA.
A COLD FRONT CROSSES THE WATERS MONDAY NIGHT AND MAY CAUSE
SCATTERED THUNDERSTORMS.
