The episode as NWS BOX wrote it up.
An upper level disturbance rotated across Southern New England, producing showers and thunderstorms. One of these storms became severe producing damaging winds. In addition, advisory level flooding occurred in several towns where thunderstorms passed overhead.
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 13, 2:42 PM EST, 1 hour 45 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE TAUNTON MA 342 PM EDT WED JUL 13 2011 .SYNOPSIS... A MID LEVEL DISTURBANCE AND SURFACE TROUGH WILL MOVE ACROSS THE REGION THIS AFTERNOON AND EVENING...AND WILL LIKELY TRIGGER SCATTERED THUNDERSTORMS. HIGH PRESSURE WILL BRING DRIER AND LESS HUMID CONDITIONS FRIDAY AND SATURDAY. HUMIDITY AND TEMPERATURES WILL GRADUALLY INCREASE SUNDAY. A COLD FRONT WILL AFFECT SOUTHERN NEW ENGLAND MONDAY AND TUE. && .NEAR TERM /UNTIL 10 PM THIS EVENING/... 345 PM UPDATE...STRONG SHORTWAVE MOVING ACROSS THE U.S./CANADA BORDER PER WATER VAPOR IMAGERY. THIS WITH ACCOMPANYING COLD POOL ALOFT IS PRODUCING SHOWERS AND THUNDERSTORMS ON THE BORDER AND SPREADING ACROSS NEW ENGLAND. THESE STORMS ARE PROPAGATING SOUTHEASTWARD MOVING INTO AN AREA OF DECENT SHEAR /40-50 KTS/ AND MODEST CAPE /500-1000 J/KG/. WITH AVAILABLE INSTABILITY AND THE COLD POOL ALOFT...THE STRONGEST OF THESE STORMS WILL BE CAPABLE OF PRODUCING SMALL HAIL AND GUSTY WINDS. THE BEST INSTABILITY OVER SOUTHERN NEW ENGLAND IS STILL FORECAST TO BE LATE THIS AFTERNOON AND EVENING. AT LEAST SCATTERED CUMULUS CLOUD COVER ACROSS THE REGION...SOME AREAS ALSO HAVE A CEILING OF MID AND HIGH LEVEL CLOUDS. THE THICKER CLOUD COVER HAS LIMITED TEMPERATURES SOMEWHAT ACROSS NORTHWEST MASS AND SOUTHWEST NH AS WELL AS THE CAPE AND ISLANDS. TEMPS IN THESE AREAS ARE IN THE UPPER 70S TO LOW 80S WHILE ELSEWHERE ACROSS THE REGION...TEMPERATURES ARE REACHING INTO THE MID TO UPPER 80S. THE SEABREEZE ALONG THE EAST COAST HAS FINALLY DEVELOPED...KEEPING NEAR SHORE AREAS A FEW DEGREES COOLER THAN NEARBY INLAND LOCATIONS. && .SHORT TERM /10 PM THIS EVENING THROUGH THURSDAY NIGHT/... OVERNIGHT...SCATTERED SHOWERS AND THUNDERSTORMS SHOULD HAVE DISSIPATED OR MOVED OFFSHORE BY MIDNIGHT. A FEW WEAKENING SHOWERS/STORMS MAY LINGER ALONG THE EAST COAST AND CAPE WITH THE SURFACE TROUGH. THESE SHOULD MOVE OFFSHORE OR DIMINISH COMPLETELY BY SUNRISE. BEHIND THIS TROUGH...COOLER AND NOTICEABLY LESS HUMID AIR WILL OVERSPREAD THE REGION. EXPECT CLEARING SKIES OVERNIGHT...WITH TEMPS FALLING TO THE MID AND UPPER 50S ACROSS THE FAR INTERIOR...UPPER 50S TO MID 60S ELSEWHERE. THURSDAY...HIGH PRESSURE BUILDS INTO THE REGION FROM THE GREAT LAKES. DEWPOINTS FALL INTO THE UPPER 40S TO LOW 50S...RESULTING IN FAR MORE COMFORTABLE CONDITIONS. BOUNTIFUL SUNSHINE AND TEMPERATURES AROUND 80 DEGREES MAKE FOR A WONDERFUL DAY TO BE OUTDOORS. NOT SURE IF THE GRADIENT WILL WEAKEN ENOUGH FOR SEA BREEZES TO FORM...BUT THEY DO REMAIN A POSSIBILITY. LOW DEWPOINTS REMAIN IN THE AREA THROUGH THE NIGHT...AND COUPLED WITH GOOD RADIATIONAL COOLING CONDITIONS WILL RESULT IN LOW TEMPERATURES DROPPING DOWN TO AROUND 50 IN THE FAR INTERIOR AND IN THE MID TO UPPER 50S ACROSS THE REST OF THE REGION. THERE IS A MODERATE RISK OF RIP CURRENTS ON THE EAST FACING SHORELINES THURSDAY. SEE THE SURF ZONE FORECAST /SRFBOX/ FOR MORE DETAILS. && .LONG TERM /FRIDAY THROUGH WEDNESDAY/... HIGHLIGHTS... * HIGH PRESSURE DOMINATES THROUGH SUN * A COLD FRONT WILL AFFECT THE REGION MON AND TUE OVERALL... MODELS CONTINUE TO SHOW GOOD AGREEMENT ON THE SYNOPTIC PATTERN THROUGH NEXT WEEK. STRONG UPPER LVL SUBTROPICAL RIDGE CONTINUES TO BUILD TOWARD THE N AND E FROM THE CENTRAL PLAINS. THIS ALLOWS FLOW TO WEAKEN ALOFT...PUSHING PRIMARY TIME MEAN JET TO THE N. SUBSIDENCE AND DRY AIR AT ALL LVLS LOOK TO DOMINATE THE COLUMN RIGHT THROUGH EARLY NEXT WEEK. THE NEXT MAJOR PATTERN SHIFT LOOKS TO BEGIN SUN NIGHT INTO MON...AS MODELS CONTINUE TO FAVOR ROBUST NRN QC CUTOFF BEGINS TO DIVE TOWARD THE SE PUSHING THE PRIMARY JET TO THE S AND IN CLOSER PROXIMITY TO SNE. WHILE THERE IS AN AGREEMENT THAT THE SFC REFLECTION OF THIS FEATURE IS A SLOW MOVING SFC LOW WELL TO THE N...ITS ATTENDANT COLD FRONT WILL LIKELY EFFECT THE REGION SOMETIME DURING THE SUN NIGHT TO MON TIME FRAME. THIS IS WHERE MODELS DIVERGE IN SOLNS A BIT...ECMWF IS CURRENTLY A BIT FASTER WHILE OPNL GFS AND GEFS MEAN ARE A BIT SLOWER. THIS DIFFERENCE IS MOST LIKELY DUE TO THE FACT THAT ECMWF IS PUSHES THE NWLY FLOW ALOFT FURTHER S...KEEPING KEEPING THE FLOW PERPENDICULAR TO THE FRONT. WITH STRONG SUBTROPICAL RIDGING STILL ENTRENCHED TO THE SW...THINK THE SLOWER SOLN IS FAVORED...WITH BEST JET DYNAMICS REMAINING N. FROM THERE THROUGH MID NEXT WEEK...MODELS GENERALLY AGREE ON THE OVERALL PATTERN...SUGGESTING A STALLING FRONT SOMEWHERE IN THE VICINITY OF SNE WITH A SECOND COOL AND DRY HIGH PRES BUILDING OVER THE REGION FROM ON AND QC. THERE IS A FAIR AMOUNT OF UNSTABLE AIR ROTATING AROUND THE SUBTROPICAL RIDGE...AND AS SUCH...MODELS ARE TRYING TO BRING A WEAKENING MCS THROUGH THE AREA SOMETIME DURING MID WEEK AFTER THE FRONT PUSHES JUST TO THE S. NO STRONG CONFIDENCE IN ANY OF THESE FEATURES ATTM...BUT IT WILL HAVE TO BE MONITORED AS THE TIME APPROACHES. FRI THRU SUN... HIGH PRES BUILDS OVER SNE THROUGH THE PERIOD. COLUMN LOOKS DRY FRI AND SAT WITH DWPTS IN THE 50S EXPECTED FOR BOTH DAYS. MIXING TO H85 OR EVEN H8 IS LIKELY DURING BOTH OF THESE DAYS...SO EXPECTING THE H85 TEMPS OF 13 TO 15C TO BE FULLY REALIZED. SUGGESTING HIGHS REACHING WELL INTO THE 80S. THE LOW DWPTS AND MOSTLY CLEAR SKIES WITH A DRY COLUMN SUGGEST OVERNIGHT MINS DIP INTO THE MID 50S IN COOLER SPOTS. SUN RETURN FLOW BEGINS WITH INCREASING LLVL MOISTURE AND WAA AS THE HIGH PUSHES TO THE E. WHILE DWPTS AND MID LVL TEMPS INCREASE...SUGGESTING WARMER TEMPS...THE OTHER ISSUE THAT MAY COME INTO PLAY FOR SUN HIGHS WILL BE THE POTENTIAL FOR INCREASING CLOUD COVER IN ADVANCE OF STRONG SHORTWAVE TO THE N. GIVEN THIS...NOT EXPECTING MIXING TO REACH AS HIGH OF A LVL AS PREVIOUS DAYS. H85 TEMPS OF 16 TO 18C...COULD STILL PROMOTE UPPER 80S TO LOWER 90S IN THE CT VALLEY WHERE DOWNSLOPE MAY CONTRIBUTE. SUN NIGHT THRU TUE... AS MENTIONED EARLIER STRONG LOW PRES WELL TO THE N WILL DRAG ITS ATTENDANT COLD FRONT THROUGH THE AREA DURING SUN NIGHT THRU MON PERIOD. WHILE THE ECMWF REMAINS THE FASTER SOLN...THE GFS/GEFS SOLN IS MORE FAVORABLE GIVEN THE SUGGESTED UPPER LVL PATTERN. THIS KEEPS SUN NIGHT HUMID WITH INCREASING CLOUD COVER BUT DRY IN TERMS OF PRECIP. DURING THE DAY MON...THE FRONT WILL APPROACH THE NW CORNER OF MA. WITH MID LVL LAPSE RATES INCREASING TO AROUND 6.5C/KM AND THE COLUMN SUPPORTING CAPES OF 1000 TO 1500 J/KG...THE FRONT/PRE FRONTAL TROF WILL LIKELY BE A FOCAL POINT FOR CONVECTION. THE BEST SHEAR/JET DYNAMICS REMAIN TO THE N...BUT WITH DECREASING STABILITY AND FAIRLY ROBUST LIFT TSTMS WILL BE A THREAT DURING THE DAY MON. MODELS THEN DISAGREE WITH THE PASSAGE OF THE FRONT...PUSHING IT S OF SNE. CURRENTLY...THE MOST LIKELY SCENARIO KEEPS THE FRONT JUST S OF SNE THROUGH CENTRAL NJ. THIS MAY KEEP THE THREAT FOR CONTINUED ACTIVITY INTO TUE. THE PRIMARY CHANGE TO THIS WILL BE THE NATURE OF THE DRY AIR BUILDING IN WITH HIGH PRES BEHIND THE FRONT. FOR NOW...WILL CONTINUE THE THREAT OF AT LEAST SOME DIURNALLY DRIVEN -SHRA/TSTM ACTIVITY TUE AND INTO MID WEEK. && .AVIATION /20Z WEDNESDAY THROUGH MONDAY/... FORECASTER CONFIDENCE LEVELS... LOW...LESS THAN 30 PERCENT MODERATE...30 PERCENT TO 60 PERCENT HIGH...GREATER THAN 60 PERCENT THIS AFTERNOON...HIGH CONFIDENCE FOR VFR ALL TERMINALS.

LOW TO MEDIUM CONFIDENCE OF FOG AND STRATUS REDUCING CIGS AND VSBYS OVER CAPE AND ISLAND TERMINALS BEGINNING SUN WITH S TO SW FLOW. && .MARINE... TONIGHT...ANY EVENING TSTMS WILL BE SHORT LIVED. PATCHY FOG POSSIBLE LATE. N WINDS INCREASE AFTER MIDNIGHT WITH OCCASIONAL GUSTS TO 20 KTS POSSIBLE.
