The episode as NWS BOX wrote it up.
After thunderstorms occurred during the early morning hours, clouds cleared allowing for ample sunshine. This resulted in the atmosphere destabilizing. A cold front moved through the region producing showers and thunderstorms. Some of these storms became severe producing damaging winds. High rainfall rates in a moisture laden atmosphere resulted in flash flooding as well.
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 Aug 15, 12:44 PM EST, 1 hour 1 minute earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE TAUNTON MA 144 PM EDT WED AUG 15 2012 .SYNOPSIS... WEAK LOW PRESSURE AND A FRONTAL SYSTEM WILL SLOWLY WORK ITS WAY ACROSS SOUTHERN NEW ENGLAND THIS AFTERNOON THROUGH THU MORNING... EXITING THE COAST THU AFTERNOON. SHOWERS AND THUNDERSTORMS WILL BE LIKELY THROUGH EARLY THURSDAY AFTERNOON. AFTER A BRIEF DRY SPELL... ANOTHER COLD FRONT WILL LIKELY BRING ADDITIONAL SCATTERED SHOWERS AND THUNDERSTORMS LATE FRI INTO THE WEEKEND. HIGH PRESSURE SHOULD BRING DRY AND COOLER WEATHER TO THE REGION EARLY NEXT WEEK. && .NEAR TERM /UNTIL 6 PM THIS EVENING/... 145 PM UPDATE... ATMOSPHERE TRYING TO RECHARGE AFTER MORNING CONVECTION. SPC MESOANALYSIS SHOWS MLCAPES UP TO 1000 J/KG AND WIDELY SCT SHOWERS HAVE DEVELOPED ACROSS INTERIOR NEW ENGLAND. AS FURTHER DESTABILIZATION TAKES PLACE EXPECT COVERAGE OF SHOWERS/TSTMS TO INCREASE. 0-6KM SHEAR AND MID LEVEL LAPSE RATES ARE WEAK WHICH SHOULD INITIALLY LIMIT INTENSITY OF ANY STORMS...BUT TOWARD 00Z AS SHORTWAVE ENERGY APPROACHES LAPSE RATES AND SHEAR ARE EXPECTED TO INCREASE WHICH MAY LEAD TO A FEW STRONG OR POSSIBLY SEVERE STORMS. && .SHORT TERM /6 PM THIS EVENING THROUGH 6 PM THURSDAY/... TONIGHT... AMPLIFYING MID LEVEL TROUGH AND SHORTWAVE MOVES EAST INTO NEW ENG WHICH WILL HELP TO SUSTAIN CONVECTION INTO THE NIGHT THROUGH COOLING ALOFT AND STEEPENING MID LEVEL LAPSE RATES. IN FACT...700 TO 500 MB LAPSE RATE APPROACHES 7 DEG/KM IN WESTERN AREAS AFTER MIDNIGHT AND THE TOTAL TOTALS INDEX HITS 52 IN WESTERN AREAS AT THAT TIME PER GFS. KEPT LIKELY POPS THROUGH TONIGHT. MAVMOSGUIDBC GRIDS FOR LOWS...MAINLY MID AND UPPER 60S. THURSDAY...AT FIRST GLANCE IT APPEARS THAT ALL MODELS WANT TO SWEEP THINGS CLEAN AS THE SURFACE FRONT IS OFF THE COAST AND THE MEAN RELATIVE HUMIDITY DECREASES TO LESS THAN 40 PERCENT IN THE AFTERNOON. HOWEVER...CLOSER INSPECTION SHOWS THAT WITH THE HEART OF THE COLD POOL... -14C...STILL IN THE VICINITY IN THE MORNING... ANY SUNSHINE WILL MAKE US VERY UNSTABLE AND THERE IS A GOOD CHANCE OF POPPING STRONG TO POSSIBLY ISOLATED SEVERE STORMS IN SE NH/EASTERN MA/AND RI IN THE LATE MORNING AND EARLY AFTERNOON. THE GFS HAS A HIGH LIGHTNING ACTIVITY LEVEL...A FIRE WEATHER PARAMETER... OF 4 IN THESE AREAS AT 18Z WHICH IS A SUBTLE INDICATOR THAT THERE COULD STILL BE CONVECTION AROUND. IN ADDITION TOTAL TOTALS ARE FORECAST TO BE 50-53 ALONG THE E COAST OF MA BETWEEN 12Z AND 18Z. THUS... HAVE FORECAST 40-55 PERCENT CHANCES OF SHOWERS/TSTMS. DO EXPECT CLEARING FROM WEST TO EAST IN THE MID AFTERNOON. HIGHS IN THE MID 80S MOST AREAS. && .LONG TERM /THURSDAY NIGHT THROUGH TUESDAY/... HIGHLIGHTS... *SCATTERED SHOWERS AND THUNDERSTORMS LATE FRIDAY THROUGH SATURDAY *SHOWERS MAY LINGER OVER THE EASTERN ZONES ON SUNDAY OVERVIEW... MAIN FORECAST ISSUE THIS PERIOD IS THE TIMING AND CHARACTER OF COLD FRONT THAT APPROACHES LATE FRIDAY BUT MAY TAKE MUCH OF THE WEEKEND TO CLEAR THE REGION. THE 00Z ECMWF SHOWS REASONABLY GOOD CONSISTENCY WITH ITS PRIOR RUN BUT WITH A SLOWER SOLUTION THAN THE OPERATIONAL GFS. INCLINED TO LEAN TOWARD THE SLOWER ECMWF SOLUTION GIVEN THE H5 TROF AXIS REMAINING WEST OF THE AREA THROUGH THE WEEKEND WITH SW FLOW ALOFT. THERE SEEMS TO BE SUPPORT FOR THE SLOWER SOLUTION FROM THE GFS ENSEMBLE MEAN AS WELL. THUS...HAVE KEPT CHANCE SHOWERS AND TSTMS IN THE FORECAST THRU SAT...AND OVER EASTERN AREAS EVEN ON SUN. ECMWF DEVELOPS WEAK SURFACE WAVE ON SUN AND HOLDS FRONT BACK ALONG SE COASTAL MA. THIS SOLUTION SEEMS PLAUSIBLE SINCE LARGE SCALE UPPER PATTERN DOES NOT SEEM CONDUCIVE TOWARDS SWEEPING THE FRONT OUT TO SEA...BUT CONFIDENCE IS RELATIVELY LOW. SOME TSTMS LATE FRI...PROBABLY WEST OF A MHT-ORH-IJD LINE...MAY BE STRONG OR EVEN SEVERE GIVEN COMBINATION OF MODERATE INSTABILITY AND VERTICAL WIND SHEAR ON THE ORDER OF 30 TO 35 KT...POSSIBLY EVEN A LITTLE HIGHER DEPENDING WHICH MODEL ONE CHOOSES. STRONG OR SEVERE TSTMS LOOK TO BE A POSSIBILITY AGAIN ON SAT GIVEN VERTICAL SHEAR/INSTABILITY COMBINATION. IN ADDITION...EXCESSIVE RAFL IS AN ISSUES AS WELL. SINCE THE FRONT DECELERATES WITH FLOW ALOFT LIKELY BECOMING NEARLY PARALLEL TO FRONTAL BOUNDARY...SEE A RISK OF FLASH FLOODING WITH TRAINING CELLS IN AIR MASS CHARACTERIZED BY PWATS PROJECTED BETWEEN 1.5 AND 1.9 INCHES. ALTHOUGH POPS HAVE BEEN KEPT IN CHANCE CATEGORY FOR NOW LATE FRI INTO WEEKEND DUE TO TIMING AND OTHER UNCERTAINTIES...POTENTIAL EXISTS FOR LOCALLY HEAVY/EXCESSIVE RAFL. BEYOND THIS WEEKEND...LOOKS DRY FOR AT LEAST A WHILE WITH THE FLOW BECOMING A LITTLE LESS AMPLIFIED. H85 TEMPS SUGGEST NEAR SEASONABLE TEMPS FOR AT LEAST MOST OF THE COMING WEEK. && .AVIATION /18Z WEDNESDAY THROUGH MONDAY/... FORECASTER CONFIDENCE LEVELS... LOW...LESS THAN 30 PERCENT MODERATE...30 PERCENT TO 60 PERCENT HIGH...GREATER THAN 60 PERCENT OVERVIEW...MODERATE CONFIDENCE. SCT SHOWERS/TSTMS TO INCREASE IN COVERAGE ACROSS THE INTERIOR THIS AFTERNOON...THEN MOVING EAST ACROSS SNE TONIGHT. A PERIOD OF MVFR CONDITIONS EXPECTED IN ANY STORMS AND PATCHY LATE NIGHT MVFR/IFR FOG POSSIBLE. MAINLY VFR THU...BUT SCT SHOWERS/TSTMS EXPECTED TO REDEVELOP ESPECIALLY FROM S NH THROUGH E MA. KBOS TERMINAL... MODERATE CONFIDENCE. NOT REALLY A TRUE SEABREEZE THIS AFTERNOON AS LOW LEVEL FLOW DRIVING SE WINDS. SCT TSTMS POSSIBLE AFTER 20Z AND MAY LINGER INTO TONIGHT. KBDL TERMINAL... MODERATE CONFIDENCE. SCT TSTMS LIKELY THIS AFTERNOON AND POSSIBLY LINGERING INTO THIS EVENING. OUTLOOK...THURSDAY NIGHT THROUGH SUNDAY... THU NIGHT THRU MOST OF FRIDAY...HIGH CONFIDENCE OF VFR.

LOCALLY HIGHER WINDS AND SEAS IN STORMS. OUTLOOK...THURSDAY NIGHT THROUGH SUNDAY... LIGHT WINDS GENERALLY LESS THAN 20 KT AND SEAS BELOW 5 FT EXPECTED THRU THE PERIOD.
