A lingering surface trough and an approaching cold front resulted in showers and thunderstorms developing across western Massachusetts. These thunderstorms produced damaging winds.
The local office's own words before the first event, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.
NWS Boston/Norton, MA wrote its last area forecast discussion before the first event at Jul 6, 2:49 PM EST, 3 hours 15 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE TAUNTON MA 349 PM EDT WED JUL 6 2011 .SYNOPSIS... A WEAK COLD FRONT WILL SLIDE THROUGH THE REGION OVERNIGHT. SHOWERS AND THUNDERSTORMS WILL DEVELOP THIS EVENING AND OVERNIGHT AHEAD OF THE FRONT BEFORE DRYING BY MORNING. THE FRONT WILL STALL JUST SOUTH OF THE REGION THURSDAY WITH SHOWERS AND THUNDERSTORMS CONTINUING ESPECIALLY SOUTH OF THE MASS PIKE. A COASTAL WAVE WILL TRACK ALONG THE STALLED FRONT AND PASS SOUTH OF NEW ENGLAND FRIDAY NIGHT AND EARLY SATURDAY BRINGING THE CHANCE OF SHOWERY WEATHER. HIGH PRESSURE WILL FOLLOW SUNDAY THEN AN APPROACHING COLD FRONT WILL BRING A CHANCE OF SHOWERS AND THUNDERSTORMS LATE MONDAY INTO EARLY TUESDAY. HIGH PRESSURE BUILDS BACK IN FOR WEDNESDAY. && .NEAR TERM /UNTIL 6 AM THURSDAY MORNING/... A COLD SHORTWAVE ROTATING THROUGH LONGWAVE TROF OVER CENTRAL QC WILL SLOWLY DRAG ITS ATTENDANT COLD FRONT THROUGH THE REGION OVERNIGHT. AIRMASS REASONABLY UNSTABLE OUT AHEAD OF THE FRONT THIS AFTERNOON AND EVENING WILL YIELD TSTMS WITH ISOLD SVR EVENTS LIKELY THROUGH THE EARLY PART OF THE OVERNIGHT. CURRENTLY CONVECTION IS FORMING A DISCRETE LINE ALONG THE PRE FRONTAL TROF THROUGH NRN NY AND VT WITH A FEW ISOLD CELLS IN THE MOST UNSTABLE AIR THROUGH ALY CWA. THIS WILL CONTINUE TO TRANSLATE TO THE E...WITH BEST TIME OF ARRIVAL BEING THE EVENING INTO EARLY OVERNIGHT. WITH REASONABLE CAPE IN THE -10 TO -20C COLUMN...AND INCREASING WINDS ALOFT...HAIL AND WINDS STILL LOOK TO BE THE PRIMARY THREAT. DOWNBURSTS UNDER GOOD CORES WILL BE THE THREAT FOR ISOLATED CELLS...THE DISCRETE LINE MAY BE AN ISSUE IF LLVL JET CAN TRANSLATE TO THE GROUND IN ANY BOWING SEGMENTS. TRENDED CONVECTION TIMING TOWARD THE HRRR...WHICH HANDLED THE LINE FORMATION WELL THIS AFTN. MODEL SOUNDINGS CONTINUE TO SUGGEST SOME WEAK ELEVATED CAPE ACROSS NRN PORTIONS OF THE REGION WITH MARGINAL SHEAR VALUES OF 35 KTS 0 TO 3KM...AND AROUND 40 KTS 0 TO 6KM. WHILE THERE IS STILL SOME WARM AIR ALOFT HOLDING MLCAPES AROUND 1000 J/KG...SUSPECT THAT THIS WILL DWINDLE AFTER SUNSET AND A WEAK LLVL INVERSION FORMS. ANY ELEVATED CONVECTIVE CELLS WILL LIKELY BE MUCH WEAKER DURING THE OVERNIGHT HOURS AS A RESULT AND THE BEST SHEAR MOVES TO MOSTLY BEHIND THE FRONT. THEREFORE WILL SLOWLY DIMINISH POPS WITH TSTM/-SHRA OVER THE REGION THROUGH THE OVERNIGHT HOURS UNTIL ITS MOSTLY DRY TOWARD AROUND SUNRISE. CLOUD COVER...AND LITTLE COOL AIR BEHIND THE FRONT SUGGESTS ANOTHER WARM AND HUMID NIGHT. && .SHORT TERM /6 AM THURSDAY MORNING THROUGH THURSDAY NIGHT/... THURSDAY... THE TIMING AND MOVEMENT OF THE SLOW COULD FRONT IS NOW FALLING INTO A CONSENSUS BETWEEN MODELS. CURRENTLY IT LOOKS LIKE THE FRONT WILL BE ORIENTED SW TO NE FROM A NYC TO BOS LINE. FLOW ALOFT IS NEARLY PARALLEL TO THE FRONT AT THIS POINT...SO SUSPECT IT WILL SLOW DOWN DURING THE MORNING HOURS AND STALL ALONG THE SE COAST IN THE AFTERNOON. IN THE NW FLOW TO THE N...INSTABILITY WILL BE HARD TO COME BY WITH CAA AND DRY AIR PUSHING IN. HOWEVER...CAPE VALUES IN CLOSE PROXIMITY TO THE FRONT WILL BE APPROACHING THE 500 TO 1000 J/KG EVEN WITH MODEST MID LVL LAPSE RATES OF 5.5 TO 6.0C/KM. THEREFORE...WITH A FOCAL POINT FOR LIFT...AND SOME MODEST CAPE VALUES...SUSPECT ANOTHER ROUND OF DIURNALLY DRIVEN -SHRA/TSTMS WILL DEVELOP S OF THE MA PIKE. CURRENTLY...BEST SHEAR LOOKS TO BE N OF THE FRONT...THEREFORE SUSPECT MOST TSTMS WILL BE SUB SVR...BUT AN ISOLD SVR CANNOT BE RULED OUT. FOR NOW...IT LOOKS AS THOUGH BEST CHANCE FOR SVR WILL STAY WELL S OF THE REGION. TEMPS DURING THE DAY WILL BE COOLER THAN PREVIOUS DAYS WITH COOLER AIR ADVECTING IN TO THE N AND SOME CLOUD COVER EXPECTED OVER SRN PORTIONS OF THE FA. LEANED TOWARD A COOLER BLEND OF BIAS CORRECTED MOS GUIDANCE. THU NIGHT... A FEW LINGERING -SHRA/TSTMS WILL CONTINUE ACROSS SRN PORTIONS OF THE FA INTO THE OVERNIGHT. CAPE AND SVR INDICES DROP OFF QUICKLY LATE IN THE EVENING...SO WILL LIKELY SEE A TREND TOWARD DRY AND CLEARING CONDITIONS BEFORE MIDNIGHT. WEAK RIDGE AND ATTENDANT SFC HIGH WILL BEGIN TO CREST OVER THE REGION AS WELL. THIS SHOULD ALLOW THE FRONT TO SAG FAR ENOUGH S OF THE REGION FOR A MOSTLY DRY...AND EVEN SOMEWHAT CLEAR LATE NIGHT AND EARLY MORNING. WILL TREND GRIDS TOWARD THIS DRY TREND. TEMPS WILL BE COOLER OVERNIGHT WITH DRY AND COOL AIR BUILDING IN COMBINING WITH WEAK FLOW UNDER HIGH PRES. RADIATIVE PROCESSES MAY BE IN FULL SWING ESPECIALLY IF NRN AREAS GO CLEAR. MOS CONSENSUS LOOKED REASONABLE...SO USED IT FOR MINS. && .LONG TERM /FRIDAY THROUGH TUESDAY/... HIGHLIGHTS... * CHANCE OF SHOWERS AND THUNDERSTORMS LATE FRIDAY INTO SATURDAY * WARMER AND MAINLY DRY WEATHER SUNDAY INTO MONDAY * A COLD FRONT BRINGS CHANCE OF MORE SHOWERS AND THUNDERSTORMS LATE MONDAY INTO TUESDAY OVERVIEW... 12Z MEDIUM RANGE GUIDANCE IN DECENT AGREEMENT ON OVERALL PATTERN DURING THE EXTENDED PERIOD. GT LAKES MID LEVEL TROF AMPLIFIES A BIT AS IT MOVES THROUGH NEW ENG EARLY SAT BEFORE LIFTING OUT. LARGE SUBTROPICAL RIDGE BUILDS FROM THE CENTRAL PLAINS TO THE SOUTHEAST US THROUGH NEXT WEEK WITH NORTHERN TIER STATES ON THE NORTHERN PERIPHERY OF THE RIDGE. SHORTWAVES MOVING THROUGH THE WESTERLIES WILL DELIVER A COLD FRONT TUE WITH MID LEVEL TROF AMPLIFYING AGAIN EAST OF NEW ENG BY MID WEEK. NEAR OR SLIGHTLY BELOW NORMAL TEMPS FRIDAY AND SATURDAY THEN ABOVE NORMAL TEMPS EXPECTED SUNDAY THROUGH TUESDAY. FRIDAY... STALLED BOUNDARY TO THE SOUTH WITH WEAK HIGH PRES OVER THE REGION WILL RESULT IN LIGHT EASTERLY FLOW WHICH WILL GRADUALLY VEER TO MORE SOUTHERLY AS THE RIDGE MOVES OFFSHORE. MODELS DISAGREE ON EXTENT OF MOISTURE RETURN DURING THE AFTERNOON. NAM LOOKS TOO SUPPRESSED WITH MOISTURE AND SUSPECT THERE WILL BE SOME THREAT OF SHOWERS/TSTMS DURING THE AFTERNOON...ESPECIALLY SW ZONES AS DEEPER MOISTURE TRIES TO RETURN NORTHWARD WITH MARGINAL INSTABILITY DEVELOPING. WE HAVE CHC POPS S OF THE PIKE WITH SLIGHT CHC TO THE N. USED A MAV/MET BLEND FOR TEMPS...GENERALLY UPPER 70S TO LOWER 80S. INTERESTING EVOLUTION OF EVENTS FRI NIGHT AS SOME OF THE GUIDANCE IS SUGGESTING A WAVE DEVELOPING ALONG THE STALLED BOUNDARY TO THE S THEN LIFTING NE AND PASSING S OF THE BENCHMARK. NAM ACTUALLY IS GOING WARM CORE WITH THIS SYSTEM BUT WE DISCOUNTED ITS SOLUTION. THE THREAT OF SHOWERS AND ELEVATED TSTMS WILL CONTINUE INTO FRI NIGHT AND HAVE HIGHEST POPS CONFINED TO S OF THE PIKE. SATURDAY... DEEPER MOISTURE MOVES EWD IN THE MORNING...BUT MID LEVEL TROF IS FORECAST TO MOVE THROUGH BY EARLY AFTERNOON AND MODELS GENERATE ENOUGH INSTABILITY WITH DECENT TT VALUES AND A THETA-E RIDGE TO SUPPORT A FEW SHOWERS/TSTMS DEVELOPING...ESPECIALLY INTERIOR SO WE HAVE CHC POPS. TEMPS MAINLY UPPER 70S TO LOWER 80S. SUNDAY... LOOKS DRY AND WARMER AS HEIGHTS RISE AND HIGH PRES BUILDS IN. 850 MB TEMPS WARMING TO NEAR 16C WHICH SHOULD ALLOW TEMPS TO REACH WELL INTO THE 80S. MONDAY... INCREASING SW FLOW AHEAD OF COLD FRONT MOVING THROUGH THE GT LAKES WILL ADVECT HIGHER DEWPOINTS INTO REGION AND VERY WARM LOW LEVEL TEMPS AS 850 MB TEMPS WARM TO NEAR 19C. MAX TEMPS WILL LIKELY REACH THE LOWER 90S IN THE INTERIOR. DECENT INSTABILITY AXIS IS FORECAST TO MOVE IN FROM THE WEST WHICH WILL LEAD TO CHC SHOWERS/TSTMS... ESPECIALLY INTERIOR AND HAVE CHC POPS. EXPANDED POPS ACROSS ALL SNE MON NIGHT AS THE FRONT BEGINS TO MOVE INTO THE REGION FROM THE NW. TUESDAY... TIMING IS UNCERTAIN THIS FAR OUT BUT LATEST GUIDANCE SUGGEST FRONT MOVING THROUGH THE REGION AND PASSING S OF THE COAST BY EVENING. CONTINUED CHC SHOWERS/TSTMS. 850 MB TEMPS 16-18C SO ANOTHER WARM DAY WITH TEMPS WELL INTO THE 80S AND MAY SEE A FEW 90+ DEGREE READINGS DEPENDING ON AMOUNT OF SUNSHINE. WEDNESDAY... POST FRONTAL AIRMASS WITH HIGH PRES BUILDING IN SO DRY WEATHER AND STILL WARM AS AIRMASS NOT THAT COOL BEHIND THE FRONT. 850 MB TEMPS STILL 13-14C SO MAX TEMPS SHOULD TOP OUT IN THE 80S. && .AVIATION /19Z WEDNESDAY THROUGH MONDAY/... FORECASTER CONFIDENCE LEVELS... LOW...LESS THAN 30 PERCENT MODERATE...30 PERCENT TO 60 PERCENT HIGH...GREATER THAN 60 PERCENT REST OF TODAY...SOME HIGH CLOUDS ARE MOVING IN ADVANCE OF SHORTWAVE FROM THE S AND SHORTWAVE OVER SRN QC ATTM. THE ATTENDANT SLOW MOVING COLD FRONT ALLOW FOR A BUILDUP OF LOW VFR CLOUDS WITH SOME CB N AND W OF ORH. EXPECT SOME LATE -SHRA/TSTMS TO DEVELOP IN THE SAME AREA AS THE EXPECTED CB. HIGH CONFIDENCE VFR. LOW STRATUS AND FOG CONTINUE WITH MVFR/IFR VSBYS AND CIGS AT KACK. TONIGHT... MEDIUM CONFIDENCE VFR WITH A MIX OF MVFR IN LINGERING -SHRA/TSTMS AHEAD OF A COLD FRONT. ANY RAINFALL WILL LIKELY YIELD FOG DEVELOPMENT AFTER THE COLD FRONT LATE WITH LOCALIZED MVFR AND IFR VSBYS. LOW CONFIDENCE IN TIMING. THURSDAY... MEDIUM CONFIDENCE VFR. SFC COLD FRONT WILL LIE IN PROXIMITY TO THE S COAST OF NEW ENGLAND ACTING AS A FOCUS FOR POSSIBLY ADDITIONAL SHRA/TSRA DEVELOPMENT...THE BETTER CHANCES OF WHICH WILL OCCUR S OF THE MASS PIKE. LOW CONFIDENCE ON TIMING AND DEVELOPMENT. WILL SEE VRB FLOW FOR THE S TERMINALS...MORE W/NW THRU THE INTERIOR. ANTICIPATED FOG OVER THE CAPE/ISLANDS MAY HAVE MORE DIFFICULTY BURNING OFF DURING THE MORNING HRS DUE TO THE LOCALITY OF THE COLD FRONT. THURSDAY NIGHT...MEDIUM CONFIDENCE VFR AT MOST TERMINALS SAVE FOR LOCALIZED MVFR IN -SHRA/TSTMS S OF THE MA PIKE WHERE A COLD FRONT WILL SLOWLY SHIFT TOWARD THE S. FOG MAY DEVELOP OVER ISLANDS AGAIN THU NIGHT. KBOS TERMINAL...MEDIUM TO HIGH CONFIDENCE VFR THROUGH THU. A SLOW MOVING COLD FRONT WILL PASS OVER THE REGION LATE TONIGHT AND BE BY THE TERMINAL BY THU MORNING. LOW CONFIDENCE IN TSTM/-SHRA DEVELOPMENT AHEAD OF THE FRONT EARLY IN THE OVERNIGHT WITH LOCALIZED MVFR VSBYS AND CIGS. EXPECT MOSTLY VFR AFTER FROPA ON THU. OUTLOOK...FRIDAY THROUGH MONDAY... FRIDAY INTO SATURDAY... LOW TO MEDIUM CONFIDENCE. VFR MOST OF THE TIME...BUT PERIODS OF MVFR POSSIBLE IN SCT SHOWERS/TSTMS FRI AFTERNOON INTO SATURDAY.
