The episode as NWS BOX wrote it up.
An upper level disturbance moved over southern New England, igniting showers and thunderstorms. With plenty of instability, but little shear, the main threat with these storms was heavy rain. However, one of the storms did become severe producing damaging winds in Tolland County.
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 Jun 25, 5:53 PM EST, 2 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE TAUNTON MA 653 PM EDT TUE JUN 25 2013 .SYNOPSIS... WARM AND MUGGY CONDITIONS WILL CONTINUE AS SHOWERS AND THUNDERSTORMS BECOME MORE WIDESPREAD INTO THE END OF THE WEEK. WHILE HEAVY RAIN WITH POTENTIAL LOCALIZED FLOODING IS THE PRIMARY THREAT...STRONG THUNDERSTORMS WILL BE POSSIBLE AS A COLD FRONT SLOWLY APPROACHES FROM THE WEST THIS WEEKEND INTO EARLY NEXT WEEK. && .NEAR TERM /UNTIL 10 PM THIS EVENING/... 650 PM UPDATE... ***HIT AND MISS STRONG THUNDERSTORMS WITH HEAVY RAIN THIS EVENING*** A SHORTWAVE MOVING INTO OUR REGION WAS COMBINING WITH WITH MLCAPE VALUES OF 1000 TO 1500 J/KG ANDS STEEP LOW LEVEL LAPSE RATES. THIS WAS ALLOWING SCATTERED HIT AND MISS THUNDERSTORMS TO FINALLY MOVE INTO SOUTHERN NEW ENGLAND. WHILE 0 TO 6 KM SHEAR WAS LIMITED...THE STEEP LOW LEVEL LAPSE RATES WERE ALLOWING FOR THE ONE/S CURRENTLY ENTERING INTERIOR SOUTHERN NEW ENGLAND TO PRODUCE WIND GUSTS OF 40 TO 50 MPH. A FEW STORMS COULD GO MARGINALLY SEVERE OVER THE NEXT HOUR OR TWO...BUT THE MAJORITY WILL REMAIN BELOW SEVERE LIMITS. HOWEVER...HEAVY RAIN AND DANGEROUS CLOUD TO GROUND LIGHTNING WILL BE THE BIGGEST CONCERNS WITH M0ST OF THE THUNDERSTORMS. THE ACTIVITY WILL BE HIT AND MISS AND WILL PERSIST INTO THE FIRST HALF OF THE EVENING. SHOULD SEE THE BULK OF ACTIVITY END BY LATE EVENING AND ESPECIALLY AFTER MIDNIGHT...WITH THE LOSS OF DAYTIME HEATING. && .SHORT TERM /10 PM THIS EVENING THROUGH WEDNESDAY NIGHT/... TONIGHT...ANY LINGERING SHOWERS AND THUNDERSTORMS WILL DIMINISH LATE TONIGHT. WILL BE ANOTHER WARM AND MUGGY NIGHT WITH LOW TEMPERATURES IN THE UPPER 60S TO THE LOWER 70S. FOG IS A POSSIBILITY AGAIN TONIGHT WITH THE BEST CHANCE ACROSS THE SOUTH COAST...CAPE...AND ISLANDS. WEDNESDAY...SHOWERS AND THUNDERSTORMS ARE LIKELY ONCE AGAIN. THERE IS ACTUALLY A BETTER CHANCE WEDNESDAY THAN TODAY WITH A SHORTWAVE MOVING ACROSS SOUTHERN NEW ENGLAND INCREASING SHEAR AND PROVIDING A TRIGGER. THE HEAT AND HUMIDITY SHOULD CONTINUE WHICH WILL KEEP CAPE VALUES HIGH. SO WITH PLENTY OF INSTABILITY...25 TO 30 KTS OF SHEAR AND PLENTY OF MOISTURE WITH PWATS UP TO 2 INCHES...EXPECT THUNDERSTORMS WITH HEAVY RAIN AND STRONG TO DAMAGING WINDS. TEMPERATURES WILL BE A BIT COOLER...PARTICULARLY ACROSS THE NORTHERN ZONES WHERE A BACK DOOR COLD FRONT MAY TRY TO EDGE IN. EXPECT HIGHEST TEMPERATURES IN THE UPPER 80S TO LOW 90S ALONG AND SOUTH OF THE MASS PIKE AND SLIGHTLY COOLER TEMPERATURES NORTH OF THE MASS PIKE WITH HIGHS IN THE MID 80S. WEDNESDAY NIGHT...COOLER TEMPERATURE TREND WILL CONTINUE WITH THE BACK DOOR FRONT CONTINUING TO MOVE SOUTHWARD THROUGH SOUTHERN NEW ENGLAND. EXPECT OVERNIGHT LOWS IN THE MID TO UPPER 60S. ANY CONVECTION DURING THE DAY WILL LIKELY CONTINUE FOR MUCH OF THE NIGHT WITH LIFT PROVIDED BY THE SHORTWAVE AND THE BACK DOOR FRONT. HEAVY RAIN AND ANY URBAN AND POOR DRAINAGE FLOODING WILL BE THE MAIN CONCERNS OVERNIGHT...THOUGH STRONG GUSTY WINDS AND SMALL HAIL CANNOT BE RULED OUT. ONCE AGAIN...FOG IS LIKELY...PARTICULARLY ALONG THE SOUTH COAST. && .LONG TERM /THURSDAY THROUGH TUESDAY/... HEADLINES... * HEAVY RAIN THREAT PREVAILS THROUGH MOST OF THIS TIMEFRAME * LOCALIZED URBAN AND LOW LYING AREA FLOODING IS A POSSIBILITY * STRONG THUNDERSTORMS POSSIBLE THURSDAY * CONTINUED WARM AND MUGGY CONDITIONS OVERVIEW AND MODEL PREFERENCES... MEDIUM RANGE MODELS CONTINUE TO SIGNAL HIGHLY ANOMALOUS UPPER LEVEL BLOCKING PATTERN FOR EARLY SUMMER...WITH HIGH AMPLITUDE RIDGE ACROSS THE WESTERN U.S. AND LONG WAVE TROUGH ACROSS THE E. THIS WILL KEEP THE REGION IN A RELATIVELY UNSETTLED PATTERN THANKS TO THE UPPER TROUGH/CUTOFF LOW NEAR OR TO THE W OF THE REGION...THOUGH SOME MODELS ARE TRYING TO RETROGRADE THE TROUGH A BIT FURTHER W LATE IN THE PERIOD /MON- TUE/ TO PUSH THREAT OF SHOWERS FURTHER W. ALSO NOTING SOME BRIEF BREAKS IN THE ACTION...MAINLY AROUND THE LATE THU-FRI TIMEFRAME AS SEEN ON 12Z OP RUNS OF THE GFS/GGEM AND ECMWF. THIS IS JUST ONE RUN...THOUGH...SO NOT VERY CONFIDENT. WILL STILL SEE PROLONGED PERIOD OF WARM AND HUMID CONDITIONS. WITH HIGH PWATS...ON THE ORDER OF 1.7 TO AROUND 2 INCHES WITH PROLONGED S-SW FLOW IN PLACE...EXPECT ANY SHOWERS/TSTMS TO PRODUCE LOCALLY HEAVY RAINFALL ESPECIALLY THU AND FRI. WILL NOT SEE A COMPLETE WASHOUT...BUT MAY SEE PERIODS OF SHOWERS/TSTMS EACH DAY. BY THIS WEEKEND...COULD SEE SOME GRADUAL IMPROVEMENT BUT THIS WILL BE DEPENDENT UPON WHETHER THE TROUGH ACTUALLY RETROGRADE AS MODELS ARE SUGGESTING. LEANED TOWARD A BLEND OF THE PREVIOUS FORECAST WITH THE WPC GUIDANCE...WHICH USED A BLEND OF THE GFS/ECMWF AND THEIR ENSEMBLE MEANS. THIS GAVE GOOD CONTINUITY TO THE LAST SEVERAL FORECASTS. DETAILS... THURSDAY-FRIDAY...CONTINUED THREAT OF SHOWERS/TSTMS DURING THIS TIMEFRAME. BEST INSTABILITY WILL BE ACROSS CENTRAL AND WESTERN AREAS THU INTO FRI MORNING SO HAVE KEPT LIKELY POPS GOING THERE. WILL ALSO SEE HEAVY RAINFALL AND POSSIBLE LOCALIZED FLOODING... THOUGH TOUGH TO PINPOINT WHERE THESE WILL OCCUR. DURING THE DAY FRIDAY INTO FRIDAY NIGHT...MAY SEE LESSER OF A CHANCE OF PRECIP AS BRIEF LULL MOVES ACROSS. WITH HIGH HUMIDITIES...CAN NOT RULE OUT THE CHANCE OF PRECIP THOUGH SO LEFT LOW CHANCE POPS GOING. WILL ALSO SEE PATCHY FOG DEVELOP EACH NIGHT/EARLY MORNING TIMEFRAME ESPECIALLY ALONG THE S COAST WITH SUCH MUGGY CONDITIONS IN PLACE. MAY SEE GUSTY WINDS ALONG THE S COAST FRIDAY AS S-SW LOW LEVEL JET SETS UP. GUSTS UP TO 25-30 KT POSSIBLE. SATURDAY-TUESDAY...WILL SEE CONTINUED CHANCE POPS FOR MOST OF THIS TIMEFRAME...THOUGH MAY SEE A SLOWLY LOWER CHANCE MON-TUE IF THE MODELS VERIFY AND TRY TO RETROGRADE INSTABILITY AXIS TO THE W. KEPT MENTION OF TSTMS MAINLY DURING THE DAYLIGHT HOURS THIS WEEKEND...THEN MOVED IT W EARLY NEXT WEEK. LOW LEVEL JET IN PLACE ON SAT MAY BRING GUSTS ALONG THE S COAST UP TO 25 KT. && .AVIATION /00Z WEDNESDAY THROUGH SUNDAY/... FORECASTER CONFIDENCE LEVELS... LOW...LESS THAN 30 PERCENT.
