Special Weather Statement, NWS Boston/Norton, MA

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE TAUNTON MA
202 AM EDT MON AUG 1 2011

.SYNOPSIS...
AN APPROACHING COLD FRONT WILL BRING SCATTERED SHOWERS AND
THUNDERSTORMS THIS AFTERNOON AND EVENING. THERE WILL BE A CHANCE
OF SHOWERS AND THUNDERSTORMS ACROSS NORTHERN AREAS TUESDAY
AFTERNOON AND IN SOUTHWEST NEW ENGLAND WEDNESDAY. DRY WEATHER IS
EXPECTED THURSDAY AND FRIDAY...THEN ANOTHER SYSTEM MAY AFFECT THE
REGION NEXT SATURDAY.

&&

.NEAR TERM /UNTIL 6 PM THIS EVENING/...

***SCATTERED STRONG TO SEVERE THUNDERSTORMS WILL AFFECT THE REGION
AFTERNOON/EVENING***

MESOSCALE UPDATE 140 AM...
SCATTERED STRONG TO SEVERE THUNDERSTORMS HAVE DEVELOPED ACROSS
SOUTHWEST NH/WESTERN MA AND NORTHERN CT EARLY THIS AFTERNOON.   ONE
STORM HAS ALREADY PULSED OVER AMHERST MA AND PRODUCED GOLF BALL
SIZED HAIL.

LATEST SPC MESO-ANALYSIS INDICATED 2000 TO 3000 J/KG OF MLCAPE
ACROSS MUCH OF THE REGION.  THESE VALUES ARE QUITE IMPRESSIVE FOR
SOUTHERN NEW ENGLAND STANDARDS AND HAVE RESULTED FROM VERY STEEP MID
LEVEL LAPSE RATES.  THE ONLY LIMITING FACTOR WAS RELATIVELY WEAK 0
TO 6 KM WIND SHEAR...GENERALLY LESS THAN 25 KNOTS.

THE RELATIVELY LIMITED SHEAR WILL PROBABLY PREVENT A WIDESPREAD/HIGH
END SEVERE WEATHER OUTBREAK.  NONETHELESS...MLCAPES ON THE ORDER OF
2000 TO 3000 J/KG AND STEEP MID LEVEL LAPSE RATES SHOULD ALLOW FOR
SCATTERED PULSE STRONG TO SEVERE THUNDERSTORMS TO CONTINUE TO
DEVELOP.  THE ACTIVITY CURRENTLY ACROSS INTERIOR SOUTHERN NEW
ENGLAND SHOULD WORK TOWARDS THE COASTAL PLAIN BY LATE
AFTERNOON/EARLY EVENING.  THE MAIN THREATS WILL BE LARGE HAIL AND/OR
DAMAGING STRAIGHT LINE WIND GUSTS WITH ANY STRONG TO SEVERE
THUNDERSTORM. HEAVY RAINFALL WITH ANY STORM MAY RESULT IN LOCALIZED
URBAN/POOR DRAINAGE STREET FLOODING.

&&

.SHORT TERM /6 PM THIS EVENING THROUGH 6 PM TUESDAY/...
TONIGHT...COLD FRONT CLEARS THE SOUTHERN WATERS BETWEEN 06Z AND 08Z.
MAY STILL SEE STRONG STORMS EVEN ON THE S COAST EARLY. SKIES WILL
BECOME MOSTLY CLEAR FROM NW-SE DURING THE NIGHT. COOLER AIR WILL
FILTER IN AS WINDS BECOME W-NW...ESPECIALLY WELL INLAND. EXPECT
OVERNIGHT LOWS IN THE MID-UPPER 50S ACROSS THE HIGHER TERRAIN OF SW
NH/W MA...RANGING TO THE MID 60S TO AROUND 70 ALONG THE E AND S
COASTS AND URBAN CENTERS.

TUESDAY...SOMEWHAT COMPLICATED FORECAST DURING THIS TIMEFRAME AS
UPPER LEVEL SYSTEM ACROSS NORTHERN NEW ENGLAND TRIES TO ROTATE
TOWARD S NH AND N MA DURING THE DAY. PRETTY GOOD INSTABILITY WITH
THE COLD POOL OF THIS SYSTEM...INCLUDING K INDICES IN THE LOWER 30S
AND TOTAL TOTALS AROUND 50 MAINLY ALONG THE E COAST. FAIRLY GOOD
MOISTURE INFLOW OFF THE OCEAN ALSO IN PLACE. BIG QUESTION AT THIS
POINT WILL BE IF THIS SYSTEM WORKS EVEN FURTHER S ACROSS THE REGION
AS A FEW MODELS ARE SUGGESTING. FOR NOW...KEPT MENTION OF SLIGHT
CHANCE TO LOW CHANCE POPS ACROSS S NH/N CENTRAL AND NE MA MAINLY FOR
THE AFTERNOON...AND DID INCLUDE MENTION OF TSTMS AS WELL WITH THE
BEST CHANCE DURING THE LATE MORNING AND AFTERNOON.

EXPECT DAYTIME HIGHS MAINLY IN THE 80S WITH AN OFFSHORE WIND.

&&

.LONG TERM /TUESDAY NIGHT THROUGH SUNDAY/...
HIGHLIGHTS...
* SHOWERS AND THUNDERSTORMS MAY CLIP SW NEW ENGLAND WEDNESDAY
* WARM AND DRY WEATHER THURSDAY AND FRIDAY
* MORE SHOWERS AND THUNDERSTORMS POSSIBLE SATURDAY

OVERVIEW...
MODELS IN GOOD AGREEMENT WITH MID LEVEL VORTEX MOVING TO THE
MARITIMES BY WEDNESDAY...BUT ARE STRUGGLING WITH THE TRACK OF A
SHORTWAVE MOVING SE FROM GT LAKES AS IT INTERACTS WITH THIS
VORTEX. THIS WILL HAVE AN IMPACT ON THE POTENTIAL FOR SHOWERS AND
THUNDERSTORMS WEDNESDAY. VORTEX LIFTS OUT TOWARD THE END OF THE
WEEK WITH FAST MOVING SHORTWAVES MOVING THROUGH THE DEAMPLIFIED
FLOW ACROSS THE NORTHERN TIER STATES. TIMING OF THESE SHORTWAVES
UNCERTAIN BUT LATEST GUIDANCE SUGGESTS ANOTHER SHORTWAVE WILL
AFFECT NEW ENG NEXT SAT.

TUE EVENING...
THERE MAY BE A FEW SHOWERS OR A THUNDERSTORM IN THE EVENING ASSOCD
WITH MID LEVEL VORTEX ACROSS MAINE. BEST CHANCE WILL BE OVER NE MA
AND S NH CLOSEST TO THE COLD POOL.

LATE TUE NIGHT INTO WEDNESDAY...
SFC WAVE ASSOCD WITH GT LAKES SHORTWAVE WILL BE TRACKING SE ALONG
A WARM FRONT. SOME SORT OF MCS IS LIKELY ALONG THIS WARM FRONT
MOVING SE FROM GT LAKES BUT THERE IS UNCERTAINTY WITH HOW CLOSE
THIS LOW TRACKS AND IF ANY PRECIP GETS INTO SNE. ADDING TO THE
UNCERTAINTY IS THAT MODEL RUN TO RUN CONSISTENCY HAS BEEN POOR.
LATEST GUIDANCE IS STILL OFFERING DIFFERENT SOLUTIONS WITH GFS
KEEPING ACTIVITY TO THE SW WHILE GGEM/SREF ARE WET. ECMWF CLIPS
SW NEW ENG.

CURRENT THINKING IS THAT PROXIMITY OF MID LEVEL VORTEX MAY ACT AS
A BLOCK DEFLECTING THIS SHORTWAVE AND SFC WAVE FURTHER SW SO WE
TRENDED AWAY FROM WET SOLUTIONS OF GGEM/SREF...BUT CONFIDENCE IS
LOW. LEANED TOWARD ECMWF SOLUTION AND HAVE SLIGHT CHC POPS SW
ZONES FROM SW MA TO S RI BUT FURTHER ADJUSTMENTS TO POPS WILL
LIKELY BE NEEDED AS WE GET CLOSER TO THE EVENT. WED TEMPS WILL BE
DEPENDENT ON EXTENT OF CLOUD COVER AND POSSIBLE PRECIP. MOST
SUNSHINE WILL LIKELY BE CONFINED TO NE ZONES WITH MOST CLOUDS
ACROSS SW ZONES.

THURSDAY AND FRIDAY...
WARM AND DRY WEATHER LIKELY AS HIGH PRES MOVES INTO REGION. THERE
MAY BE EXTRA CLOUD COVER ON THURSDAY ACROSS NE ZONES ASSOCD WITH
DEPARTING MID LEVEL VORTEX BUT CONVECTION NOT EXPECTED. TEMPS WILL
BE NEAR OR SLIGHTLY ABOVE NORMAL...BUT FRI LOOKS TO BE THE WARMER
OF THE TWO DAYS AS WARMER 850 MB TEMPS MOVE IN FROM THE WEST.

SATURDAY AND SUNDAY...
NEXT SHORTWAVE MOVES IN FROM THE WEST SATURDAY SO HAVE CHC POPS.
DISCOUNTED GFS FOR SUNDAY AS IT LOOKS TO HAVE FEEDBACK ISSUES WITH
WOUND UP SFC LOW MOVING ACROSS REGION. THIS IS NOT A LIKELY
OUTCOME SO FOLLOWED ECMWF SOLUTION WHICH HAS DRY NORTHERLY FLOW
ACROSS THE REGION. TEMPS BELOW NORMAL SATURDAY WITH POTENTIAL FOR
CLOUDS AND SHOWERS...THEN RECOVERING TO SEASONABLE NORMALS SUNDAY.

&&

.AVIATION /15Z MONDAY THROUGH FRIDAY/...
FORECASTER CONFIDENCE LEVELS...
  LOW...LESS THAN 30 PERCENT
  MODERATE...30 PERCENT TO 60 PERCENT
  HIGH...GREATER THAN 60 PERCENT

THIS AFTERNOON...
MEDIUM TO HIGH CONFIDENCE.  VFR CONDITIONS WILL CONTINUE THE
MAJORITY OF THE AFTERNOON.  HOWEVER...SCT STRONG TO SEVERE
THUNDERSTORMS WILL RESULT IN BRIEF MVFR-IFR CONDITIONS.  THE
ACTIVITY SHOULD MAINLY BE ACROSS THE INTERIOR THROUGH 19Z OR 20Z AND
THEN AFFECT THE COASTAL PLAIN BETWEEN 20Z AND 00Z.  THE POTENTIAL
EXISTS FOR HAIL AND WIND GUSTS OVER 40 KNOTS WITH THE STRONGEST
STORMS.  HOWEVER...BECAUSE THIS ACTIVITY IS HIT AND MISS WILL JUST
GO WITH CB/S IN THE TAFS. WILL UPGRADE AND INCLUDE THE POTENTIAL FOR
THUNDERSTORMS WITH BRIEF STRONG WIND GUSTS IF AND WHEN CONFIDENCE
INCREASES OF ONE PASSING OVER THE TERMINAL.

TONIGHT...
SCATTERED SHOWERS/THUNDERSTORMS SHOULD EXIT THE COASTAL PLAIN
BETWEEN 1Z AND 3Z...BUT MAY RESULT IN BRIEF MVFR-IFR CONDITIONS.
THE ACTIVITY COULD PERSIST A BIT LONGER ON THE CAPE/ISLANDS.
OTHERWISE...MEDIUM CONFIDENCE IN MAINLY VFR CONDITIONS.
HOWEVER...MVFR CONDITIONS IN PATCHY FOG MAY AFFECT PORTIONS OF THE
REGION ESPECIALLY ACROSS THE CAPE/ISLANDS LATE.

KBOS TERMINAL...
MEDIUM TO HIGH CONFIDENCE IN TAF.  GENERALLY EXPECT VFR CONDITIONS
THROUGH TONIGHT.  HOWEVER...A BRIEF STRONG THUNDERSTORM OR TWO MAY
AFFECT THE TERMINAL LATE THIS AFTERNOON/EARLY THIS EVENING.  THE
ACTIVITY IS HIT AND MISS SO CONFIDENCE WAS NOT HIGH ENOUGH TO
INCLUDE AT THIS TIME.  WILL CONTINUE TO MONITOR CONDITIONS...BUT
JUST GO WITH A CB AT THIS TIME.

OUTLOOK...TUESDAY THROUGH FRIDAY...

TUESDAY...
MODERATE CONFIDENCE FOR VFR. SECONDARY FRONT MOVES THROUGH. AT THIS
POINT...LITTLE IF ANY PRECIP EXPECTED...BUT LOW CONFIDENCE ON TIMING
AND STRENGTH OF FEATURE. APPEARS BEST SHOT WILL BE ACROSS S NH/NE
MA. MAY SEE LAYER OF CLOUDS AOA 6KFT MAINLY NEAR OR AFTER 18Z. W-SW
WINDS SHIFTING TO W-NW AS FRONT PASSES.

TUESDAY NIGHT...
MEDIUM CONFIDENCE. MAINLY VFR...BUT LOW PROB FOR ISOLD MVFR IN ANY
EVENING SHOWERS/TSTMS NE TERMINALS.

WEDNESDAY...
LOW CONFIDENCE. CONDITIONS WILL DEPEND ON TRACK OF SFC LOW MOVING
SE FROM GT LAKES. THERE COULD BE A PERIOD OF MVFR CONDITIONS IN
SHOWERS/TSTMS WITH BEST CHANCE ACROSS SW ZONES.

THURSDAY AND FRIDAY...
HIGH CONFIDENCE VFR. BKN CU THU.

&&

.MARINE...
TODAY-TONIGHT...WINDS AND SEAS WILL REMAIN BELOW SCA. MAY SEE SW
WINDS NEAR 20 KT MON AHEAD OF COLD FRONT...ESPECIALLY ON S COASTAL
WATERS. SCT SHOWERS/TSTMS TO APPROACH NE WATERS LATE THIS
AFTERNOON...THEN MOVING ACROSS THE WATERS THROUGH EARLY TONIGHT.
CHANCE OF SQUALLY WINDS AND LARGE HAIL IN SOME TSTMS. EXPECT FRONT
TO CLEAR THE WATERS BETWEEN 06Z AND 08Z TUESDAY.

TUESDAY...EXPECT ANOTHER WEAK TROUGH TO MOVE ACROSS THE WATERS
DURING THE LATE MORNING AND AFTERNOON. HOWEVER...EXPECT WINDS AND
SEAS TO REMAIN BELOW SMALL CRAFT CRITERIA. MAY SEE WIDELY SCT
SHOWERS/TSTMS ACROSS THE WATERS N OF BOSTON HARBOR TO CAPE ANN AS
UPPER LEVEL SYSTEM TRIES TO MOVE CLOSE TO THOSE WATERS.

OUTLOOK...TUESDAY NIGHT THROUGH FRIDAY...

WINDS AND SEAS LIKELY TO REMAIN BELOW SCA THRESHOLDS THROUGH THE
PERIOD.
