Special Weather Statement, NWS Boston/Norton, MA

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE TAUNTON MA
433 PM EDT THU AUG 2 2012

.SYNOPSIS...
WARM AND VERY HUMID WEATHER WILL PERSIST FOR THE NEXT SEVERAL
DAYS. A COUPLE OF WEAK FRONTS MAY BRING SCATTERED AFTERNOON AND
EVENING SHOWERS OR THUNDERSTORMS THIS AFTERNOON AND FRIDAY. A
STRONGER COLD FRONT WILL MOVE THROUGH THE REGION MONDAY AND WILL
BRING A BETTER CHANCE OF SHOWERS AND THUNDERSTORMS BOTH SUNDAY AND
MONDAY. THE FRONT WILL THEN STALL SOUTH OF NEW ENGLAND...BUT ALLOW
FOR SLIGHTLY LESS HUMID AIR TO MOVE INTO THE REGION AFTER MONDAY.
ANOTHER COLD FRONT WILL APPROACH FROM THE WEST BY THURSDAY.

&&

.NEAR TERM /UNTIL 6 AM FRIDAY MORNING/...
230 PM UPDATE...SHOWERS AND A FEW ISOLATED THUNDERSTORMS HAVE
STARTED TO POP UP ACROSS PORTIONS OF EASTERN NEW HAMPSHIRE...EASTERN
MASSACHUSETTS...AND RHODE ISLAND. EXPECT THE MAIN THREAT WITH
THESE STORMS TO BE ANY LIGHTNING AS WELL AS POTENTIALLY SOME HEAVY
RAIN WITH DEWPOINTS IN THE UPPER 60S TO AROUND 70 AND PWATS IN THE
1.5 TO 2 INCH RANGE.  PLENTY OF SURFACE BASED CAPE IN PLACE THIS
AFTERNOON /1500-2500J/KG PER SPC MESOANALYSIS PAGE/ WHICH WILL ALLOW
THESE STORMS TO CONTINUE POPPING UP THROUGH THE AFTERNOON.  MID
LEVEL LAPSE RATES AND SHEAR IS WEAK ENOUGH THAT THESE WILL BE PULSE
TYPE STORMS.

THESE STORMS WILL HAVE A LIMITED WESTWARD EXTENT AS DRY AIR AT THE
MID LEVELS HAS STARTED TO MOVE ACROSS THE WESTERN PORTIONS OF THE
AREA...AS EVIDENCED IN WATER VAPOR SATELLITE IMAGERY.  THIS MAY ALSO
LIMIT THE STORMS IN THE EAST AS IT HAS PROGRESSED AS FAR EAST AS
I-495.

TONIGHT...ANY CONVECTION THIS AFTERNOON SHOULD DIMINISH QUICKLY
BETWEEN THE DRY AIR AND THE LOSS OF DAYTIME HEATING.  PLENTY OF LOW
LEVEL MOISTURE WILL REMAIN THOUGH WITH LOW CLOUDS AND FOG LIKELY
AGAIN TONIGHT...PARTICULARLY NEAR THE COAST.  LOW TEMPERATURES WILL
BE IN THE 60S TO LOW 70S WITH DEWPOINTS IN THE SAME ARENA.  USED A
BLEND OF MOS FOR TEMPERATURES.

&&

.SHORT TERM /6 AM FRIDAY MORNING THROUGH FRIDAY NIGHT/...
FRIDAY...ANOTHER WEAK FRONT APPROACHES THE AREA.  THERE ARE SOME
DISCREPANCIES AMONGST THE MODELS AS TO HOW FAR SOUTH THE FRONT GOES
BEFORE IT WASHES OUT.  EXPECT ANOTHER ROUND OF SHOWERS AND
THUNDERSTORMS AHEAD OF THE FRONT.  THESE STORMS WILL BE MUCH LIKE
TODAY/S BUT WITH THE POTENTIAL TO DEVELOP FURTHER WEST ACROSS THE
INTERIOR ZONES.

850MB TEMPERATURES WARM TO 17-18C...SO TEMPERATURES AT THE SURFACE
SHOULD BE WARMER WITH HIGHS IN THE UPPER 80S TO LOW 90S.  DEWPOINTS
WILL BE HIGH ENOUGH THAT TEMPERATURES PARTICULARLY ACROSS THE
EASTERN ZONES WILL FEEL LIKE THEY ARE IN THE UPPER 90S.  NOT WARM
ENOUGH FOR A HEAT ADVISORY BUT IT CERTAINLY WILL BE HOT AND HUMID.

FRIDAY NIGHT...SHOWERS AND THUNDERSTORMS MAY LINGER A BIT LATER INTO
THE EVENING THAN TONIGHT THANKS TO SOME LINGERING INSTABILITY...BUT
SHOULD WEAKEN SUBSTANTIALLY AFTER SUNSET.  ANOTHER NIGHT OF LOW
CLOUDS AND FOG EXPECTED WITH PLENTY OF LOW LEVEL MOISTURE IN THE
REGION.  LOW TEMPERATURES ONCE AGAIN IN THE MID 60S TO LOW 70S.

&&

.LONG TERM /SATURDAY THROUGH THURSDAY/...
BIG PICTURE...
MODEL FORECASTS OF 500 MB FLOW ARE SIMILAR THROUGH TUESDAY.
ATLANTIC UPPER RIDGE BRINGS RISING HEIGHTS INTO NEW ENGLAND
THROUGH SUNDAY...THEN SUPPRESSES SOUTH AND EAST. SHORTWAVE THAT
INITIALIZES OVER THE PACIFIC NORTHWEST WILL CROSS THE COUNTRY THIS
WEEKEND AND CROSS NEW ENGLAND SUNDAY NIGHT AND MONDAY. THIS
SHORTWAVE WILL DRIVE A COLD FRONT THROUGH NEW ENGLAND DURING THIS
TIME. A SECOND SHORTWAVE DIVES SOUTHEAST FROM NORTHERN ONTARIO TO
MAINTAIN CYCLONIC FLOW OVER THE NORTHEAST USA THROUGH THURSDAY.
THE MODELS HANDLE THIS SECOND SHORTWAVE DIFFERENTLY...WITH THE 12Z
ECMWF SHARPER AND CONTAINING A CLOSED LOW.

SATURDAY...
A BUILDING UPPER RIDGE WOULD SUGGEST QUIET WEATHER OVER THE
WEEKEND. HOWEVER THE NAM-GFS-EMCWF SHOW A STALLED FRONT EITHER
OVER THE MASS-NH BORDER OR JUST NORTH OF OUR AREA WITH A VERY
HUMID AIRMASS IN PLACE. SB CAPES 1500-2000 J/KG AND TOTALS AROUND
50...NAM HINTS AT A THETA-E RIDGE OVER NORTHWEST MASS. NEGATIVES
INCLUDE NO STRONG JETS ALOFT TO PRODUCE DYNAMIC FORCING AND DRYING
ALOFT AS SHOWN BY MODEL SOUNDINGS. LOCAL FORCING SUCH AS COLLIDING
BOUNDARIES COULD FORCE A FEW STORMS. THE BEST CHANCE WOULD BE
EITHER IN THE INTERIOR OR ALONG THE ADJACENT SEA BREEZE FRONT. WE
WILL INCLUDE CHANCE POPS FOR SHOWERS/TSTMS. TEMPS ALOFT WILL BE
16-18C...SO MAX TEMPS SHOULD BE IN THE UPPER 80S AND AROUND 90.

SATURDAY NIGHT...
CONVECTION SHOULD DIMINISH. LIGHT WIND AND VERY HUMID AIR WILL
PROMOTE FOGGY AREAS. MIN TEMPS WILL BE 65 TO 70...NEAR DEWPOINT.

SUNDAY-MONDAY...
COLD FRONT APPROACHES FROM THE WEST WITH INCREASING SOUTHWEST FLOW
SURFACE AND ALOFT. 850 MB WINDS INCREASE TO 30-40 KNOTS.  500 MB
WINDS ARE MORE MODEST SUNDAY AT 25 KNOTS BUT REACH 40-45 KNOTS BY
MONDAY MORNING. MODELS SHOW A PRE- FRONTAL TROUGH TO OUR
SOUTHWEST WHICH COULD SERVE AS A FOCUS FOR CONVECTION. WE WILL
INCLUDE CHANCE POPS ACROSS ALL OF THE REGION SUNDAY
AFTERNOON...SOONEST IN THE WEST AND LATE IN THE DAY TOWARD CAPE
COD. PRECIPITABLE WATER VALUES ARE FORECAST AT 2.0 TO 2.25
INCHES...SO ANY SHOWERS/STORMS WILL CARRY POTENTIAL FOR HEAVY
DOWNPOURS. TEMPS ALOFT 16-18C BUT WITH MORE CLOUDS SO A LITTLE
LESS ON MAX TEMPS...GENERALLY 80S.

CHANCE OF SHOWERS/TSTMS CONTINUES UNTIL THE COLD FRONT MOVES
THROUGH ON MONDAY. THE BEST CHANCE OF PCPN OVERALL WILL COME WITH
THE PASSAGE OF THE FRONT WHICH LOOKS TO BE ON MONDAY. WE HAVE
LIKELY POPS WITH THIS EVENT ON MONDAY.

TUESDAY-WEDNESDAY-THURSDAY...
COLD FRONT STALLS SOUTH OF NEW ENGLAND. AIRMASS DEWPOINTS DRY A
LITTLE...AND MOST OF THE DEEPER MOISTURE SHOULD BE SOUTH OF THE
COAST. COULD BE SOME HIGH CLOUDS ALONG THE SOUTH COAST BUT
OTHERWISE SHOULD BE RAINFREE TUESDAY. LESS CERTIAN FOR WEDNESDAY
AND THURSDAY AS THE NEXT SHORTWAVE AND SURFACE COLD FRONT
APPROACH. MODELS SHOW POPS INCREASING TO EITHER CHANCE OR SLIGHT
CHANCE WEDNESDAY-THURSDAY. WE WILL BRING CHANCE POPS TO THE SOUTH
COAST AND SLIGHT CHANCE MOST OF THE REST OF THE FORECAST AREA.
TEMPS ARE A BLEND OF LONG RANGE GUIDENCE.

&&

.AVIATION /21Z THURSDAY THROUGH TUESDAY/...
FORECASTER CONFIDENCE LEVELS...
  LOW...LESS THAN 30 PERCENT
  MODERATE...30 PERCENT TO 60 PERCENT
  HIGH...GREATER THAN 60 PERCENT

OVERVIEW...MEDIUM CONFIDENCE.
MAINLY VFR CONDITIONS EXPECTED WITH SCT 5KFT CLOUDS. SEABREEZE HAS
DEVELOPED AND MOVED ONSHORE THE EAST COAST WITH WINDS AT BOS OUT
OF THE EAST. THIS WILL BE THE FOCUS FOR SHRA/TSRA THIS AFTN.
EXPECT SHOWER ACTIVITY TO COME TO AN END BETWEEN 22 AND 00Z.
MVFR/IFR CIGS/VSBYS REDEVELOP IN FOG AND LOW CLOUDS LATE TONIGHT
INTO FRIDAY MORNING.

KBOS TAF...MODERATE CONFIDENCE.
SEABREEZE HAS DEVELOPED AND MOVED W OF BOS SHIFTING WINDS TO THE
E. SHRA/TSRA DEVELOP BEHIND AND ALONG THE SEABREEZE FRONT THIS
AFTN/EARLY EVE.

KBDL TAF...MODERATE CONFIDENCE.
MVFR/IFR CIGS/VSBYS IN LOW CLOUDS/FOG LATE TONIGHT. OTHERWISE...
VFR.

OUTLOOK...SATURDAY THROUGH TUESADY...

SATURDAY-SUNDAY-MONDAY...MODERATE CONFIDENCE
VFR CONDITIONS IN GENERAL BUT WITH SHOWERS/TSTMS POSSIBLE EACH
DAY...EACH WITH A POTENTIAL FOR BRIEF MVFR-IFR CIGS/VSBYS. MAIN
CONCERN ASIDE FROM LIGHTNING WOULD BE FOR HEAVY RAIN...ALTHOUGH
SUNDAY-MONDAY THE CHANCE OF STRONG WIND GUSTS IN TSTMS WILL
INCREASE. AREAS OF FOG EACH NIGHT WILL CREATE IFR-LIFR CONDITIONS
ESPECIALLY CT VALLEY AND PVD-FMH-HYA-ACK.

TUESDAY...MODERATE CONFIDENCE
COLD FRONT STALL SOUTH OF NEW ENGLAND. MORNING FOG WITH AREAS OF
IFR...OTHERWISE VFR WITH WEST WIND.

&&

.MARINE...
HIGH CONFIDENCE IN WINDS AND SEAS REMAINING BELOW SCA TODAY
THROUGH FRIDAY NIGHT AS S/SW FLOW PREVAILS. THERE IS A LOW
PROBABILITY OF WIND GUSTS NEAR 20 TO 25 KTS NEARSHORE FRIDAY
AFTERNOON.  MAIN HAZARD IS LATE NIGHT AND EARLY MORNING DENSE
FOG...MAINLY ON S COASTAL WATERS.

SEAS WILL SLOWLY BUILD S OF NEW ENGLAND BUT UNDERCUT WAVEWATCH
WHICH WANTS TO BRING 5 TO 6 FT SEAS INTO S COASTAL WATERS TODAY.
OFFSHORE BUOYS NOT SHOWING MORE THAN 3 TO 5 FT THIS MORNING SO WE
THINK THIS IS MORE REALISTIC.

BEST CHANCE OF STORMS THIS AFTERNOON AND FRI AFTERNOON IS ON
NARRAGANSETT BAY...BOSTON HARBOR AND PERHAPS E MA COASTAL WATERS.

OUTLOOK...SATURDAY THROUGH TUESDAY...

LIGHT WINDS SATURDAY...THEN INCREASING SOUTHWEST WINDS SUNDAY AND
MONDAY AHEAD OF AN APPROACHING COLD FRONT. GUSTS OF 20-25 KNOTS
SUNDAY AND MONDAY WITH SEAS BUILDING 5-8 FEET ESPECIALLY ON THE
OUTER WATERS AND RI WATERS. A SMALL CRAFT ADVISORY MAY BE NEEDED
DURING SUNDAY AND MONDAY. AFTER THE COLD FRONT MOVES THROUGH ON
MONDAY...WIND SHOULD SHIFT TO WEST AND DIMINISH. SEAS WILL SUBSIDE
MONDAY NIGHT.
