A slow moving frontal boundary, combined with plenty of heat and humidity, led to the development of showers and thunderstorms during the afternoon and evening. Some of the storms were severe and produced damaging winds across parts of central and northeast Massachusetts as well as localized flash flooding.

The episode as NWS BOX wrote it up.
A slow moving frontal boundary, combined with plenty of heat and humidity, led to the development of showers and thunderstorms during the afternoon and evening. Some of the storms were severe and produced damaging winds across parts of central and northeast Massachusetts as well as localized flash flooding. Later at night, thunderstorms with torrential rainfall produced flash flooding near the South Coast and isolated damage from lightning strikes.
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 15, 2:43 PM EST, 52 minutes earlier.
AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE TAUNTON MA
343 PM EDT TUE JUL 15 2014
.SYNOPSIS...
A SLOW MOVING FRONTAL BOUNDARY WILL BRING PERIODS OF SHOWERS AND
THUNDERSTORMS THROUGH WEDNESDAY. A FEW STRONG TO SEVERE
THUNDERSTORMS ARE POSSIBLE DURING THIS TIME...ALONG WITH HEAVY
RAIN AND POSSIBLY LOCALIZED FLASH FLOODING. DRY AND LESS HUMID
WEATHER ARRIVES THU AND FRI...POSSIBLY LINGERING INTO SAT BEFORE
THE RISK OF RAIN SUNDAY.
&&
.NEAR TERM /UNTIL 10 PM THIS EVENING/...
* A FEW STRONG TO SEVERE THUNDERSTORMS POSSIBLE INTO THIS EVENING
* LOCALIZED FLASH FLOODING POSSIBLE
SCT SHOWERS/TSTMS CONTINUE TO DEVELOP ACROSS THE INTERIOR. SPC
MESOANALYSIS INDICATING SBCAPES 1500-2000 J/KG BUT MLCAPES ARE
LESS AROUND 500-1000 J/KG. 0-6KM SHEAR IS AROUND 40 KT IN W
ZONES. TEMPS HAVE COOLED A BIT AND MARGINAL INSTABILITY AND
MEAGER MID LEVEL LAPSE RATES ARE LIMITING THE SEVERE WEATHER
POTENTIAL. GIVEN THE MAGNITUDE OF SHEAR...MLCAPES AROUND 1000
J/KG IS USUALLY ENOUGH TO SUPPORT SEVERE STORMS SO THE THREAT OF
A FEW SEVERE STORMS WILL CONTINUE INTO THIS EVENING. HEAVY
RAINFALL AND FLASH FLOODING IS THE BIGGER THREAT RIGHT NOW AS
PWATS AROUND 2" SUPPORT TORRENTIAL DOWNPOURS WITH RAINFALL RATES
2"/HR. EXPECT SEVERE THREAT TO DIMINISH THIS EVENING AS MAGNITUDE
OF INSTABILITY DECREASES.
&&
.SHORT TERM /10 PM THIS EVENING THROUGH 6 PM WEDNESDAY/...
* HIGH CONFIDENCE IN HEAVY RAIN/POTENTIAL FLASH FLOODING
TONIGHT/WED
* ISOLATED SEVERE WEATHER REMAINS POSSIBLE WED IN EASTERN NEW
ENG...BUT LOW CONFIDENCE
SEVERE WEATHER THREAT WILL TRANSITION TO MAINLY A FLASH FLOOD
THREAT LATER TONIGHT THROUGH WEDNESDAY. QUITE AN ANOMALOUS PATTERN
FOR MID JULY WITH CLOSED LOW LIFTING NE FROM THE GT LAKES AND +3SD
SW UPPER LEVEL JET MOVING EAST INTO NEW ENGLAND. LOW LEVEL JET
ALSO +3SD WHICH WILL TRANSPORT ANOMALOUS PWATS 2"+ NORTH INTO SNE
AHEAD OF A SLOW MOVING COLD FRONT. SNE GETS INTO THE RIGHT
ENTRANCE REGION OF THE UPPER JET LATE TONIGHT AND WED WITH
EXCELLENT LARGE SCALE FORCING FOR ASCENT WHICH WILL ACT ON
TROPICAL MOISTURE PLUME TO BRING HEAVY RAINFALL TO SNE.
TIMING OF HEAVY RAINFALL IS MAINLY TONIGHT FOR WESTERN NEW ENG
WHICH GRADUALLY SHIFTS TO EASTERN NEW ENG VERY LATE TONIGHT AND
ESPECIALLY DURING WED AS THE FRONT AND THE LLJ MOVES EAST. STILL
ENOUGH INSTABILITY TO SUPPORT ISOLD TO SCT TSTMS WHICH WILL
ENHANCE RAINFALL RATES AND TRAINING IS POSSIBLE DUE TO THE SLOW
MOVEMENT OF THE FRONT. BEST SFC INSTABILITY DURING WED WILL
SHIFT TO EASTERN NEW ENG AND THERE IS MODEST 0-6KM SHEAR SO CANT
RULE OUT AN ISOLD STRONG TO SEVERE TSTM AS WELL. BUT CONFIDENCE IS
LOW AS CAPES WILL LIKELY BE LESS THAN 1000 J/KG SO INSTABILITY MAY
BE A LIMITING FACTOR. THE LLJ IS FOCUSED ACROSS E NEW ENG WED WITH
0-1 KM SHEAR AROUND 25 KT AND DECENT 0-1KM HELICITY SO LOW PROB
FOR AN ISOLD TORNADO IF INSTABILITY CAN BE REALIZED...BUT AGAIN
LOW CONFIDENCE IN THIS.
MID LEVEL DRYING MOVES IN FROM THE WEST WEDNESDAY AND EXPECT
SHOWERS TO END IN WESTERN NEW ENG DURING THE AFTERNOON...AND MAY
ALSO SEE SOME SUNSHINE DEVELOPING IN THE CT VALLEY.
HOWEVER...SHOWERS AND SCT TSTMS WILL PERSIST THROUGH MUCH OF THE
DAY IN E NEW ENG.
TEMPS WILL BE MOSTLY IN THE 70S DUE TO CLOUDS AND SHOWERS. A FEW
LOCATIONS IN THE CT VALLEY MAY REACH 80+. VERY HUMID IN EASTERN
ENG ENG WITH DEWPOINTS AROUND 70...BUT BECOMING LESS HUMID IN THE
WEST AS DEWPOINTS FALL THROUGH THE 60S AND POSSIBLY INTO THE 50S
BY DAYS END.
&&
.LONG TERM /WEDNESDAY NIGHT THROUGH TUESDAY/...
HIGHLIGHTS...
* LINGERING SHOWERS/STORMS POSSIBLE IN THE EAST WEDNESDAY NIGHT
* DRY WEATHER RETURNS THURSDAY THROUGH SATURDAY
* CHANCE OF SHOWERS POSSIBLE SUNDAY AND MONDAY
MODELS ARE IN GENERALLY GOOD AGREEMENT THROUGH THE EARLY PART OF
THIS WEEKEND. FOLLOWING THE COLD FRONT MOVING OFFSHORE EARLY
THURSDAY...HIGH PRESSURE BUILDS INTO SOUTHERN NEW ENGLAND THROUGH
MUCH OF THE WEEKEND. THE MODELS START TO DIVERGE EARLY NEXT WEEK
WITH THE 12Z GFS KEEPING HIGH PRESSURE OVER SOUTHERN NEW ENGLAND
THROUGH MUCH OF THE EARLY PART OF NEXT WEEK. THE 00Z ECMWF ON THE
OTHER HAND HAS LOW PRESSURE DEVELOPING IN THE OHIO VALLEY AND A WARM
FRONT EXTENDING EASTWARD JUST SOUTH OF SOUTHERN NEW ENGLAND. THIS
FRONT WILL GRADUALLY MOVE NORTHWARD BRINGING A CHANCE OF RAIN BACK
TO THE REGION. WITH SEVERE WEATHER APPROACHING THE REGION...HAVE
USED A BLEND OF THE AVAILABLE MODELS FOR THE LONG TERM PORTION OF
THE FORECAST.
WEDNESDAY NIGHT...SHOWERS AND THUNDERSTORMS LINGER ACROSS EASTERN
MASSACHUSETTS AND RHODE ISLAND AHEAD OF A COLD FRONT. THE COLD
FRONT WILL MOVE OFFSHORE BY SUNRISE BRINGING AN END TO ANY LINGERING
PRECIP. EXPECT LOW TEMPERATURES TO REMAIN FAIRLY MILD ACROSS EASTERN
AREAS WITH COOLER TEMPS IN THE DRIER AIR BEHIND THE COLD FRONT.
THURSDAY THROUGH SATURDAY...HIGH PRESSURE BUILDS INTO SOUTHERN NEW
ENGLAND BRINGING DRIER...SEASONABLE WEATHER BACK TO THE REGION.
EXPECT HIGHS GENERALLY IN THE LOW TO MID 80S AND LOWS IN THE 60S
WITH PARTLY CLOUDY SKIES.
SUNDAY AND MONDAY...HIGH PRESSURE STARTS TO MOVE OFFSHORE AS A WEAK
UPPER TROUGH STARTS TO MOVE EAST OUT OF THE GREAT LAKES.
THIS...ALONG WITH AN APPROACHING WARM FRONT WILL ALLOW FOR SHOWERS
AND POTENTIALLY THUNDERSTORMS TO DEVELOP. HOWEVER...NOT EXPECTING A
WASHOUT AT THIS TIME.

PERSISTENT SW FLOW 10-20 KT WITH A FEW GUSTS NEAR 25 KT
POSSIBLE...ESPECIALLY OVER NEARSHORE WATERS. BUILDING SEAS TO
5-7 FT OVER THE OPEN SOUTH COASTAL WATERS LATER TONIGHT INTO WED.
AREAS OF DENSE FOG WILL REDUCE VSBYS THROUGH WED...ESPECIALLY
SOUTH COASTAL WATERS. IN ADDITION...SHOWERS AND SCT TSTMS WILL
MOVE ACROSS THE WATERS LATE TONIGHT AND WED.
OUTLOOK...WEDNESDAY NIGHT THROUGH SATURDAY...
WEDNESDAY NIGHT AND THURSDAY...SEAS DIMINISH AS HIGH PRESSURE SLOWLY
BUILDS OVER THE WATERS. SEAS FALL BELOW 5 FEET ON ALL THE WATERS
SOMETIME THURSDAY AFTERNOON. SOUTHWESTERLY WINDS WEDNESDAY NIGHT
WILL SHIFT TO THE NORTHWEST THURSDAY MORNING AS A COLD FRONT CROSSES
OVER THE WATERS...SETTLING IN A GENERALLY WESTERLY DIRECTION BY
THURSDAY NIGHT.
FRIDAY THROUGH SUNDAY...QUIET BOATING WEATHER EXPECTED. LIGHT WINDS
OUT OF THE SOUTHWEST ARE EXPECTED THROUGH MUCH OF THE PERIOD.
&&
.HYDROLOGY...
POTENT SETUP FOR JULY WITH ANOMALOUS DEEP CLOSED UPPER LEVEL LOW
ACROSS THE GREAT LAKES. THIS WILL RESULT IN THE COLD FRONT MOVING
EXTREMELY SLOWLY ACROSS THE REGION AS UPPER LEVEL FLOW BECOMES
MERIDIONAL. PRECIPITABLE WATER VALUES OF 2+ INCHES WILL CONTINUE
TO AFFECT THE REGION. IN ADDITION...VERY IMPRESSIVE LOW LEVEL JET
ALSO SETS UP ACROSS THE REGION THAT IS 2 TO 3 STANDARD DEVIATIONS
ABOVE NORMAL.
HAVING A SETUP LIKE THIS COUPLED WITH EXCELLENT JET DYNAMICS IN THE
HEART OF THE SUMMER IS IDEAL FOR TORRENTIAL RAIN AND FLASH FLOODING.
THE TREND WILL BE FOR THE HEAVIEST RAIN/FLASH FLOOD THREAT TO
GRADUALLY SHIFT TOWARDS THE COAST. THE MAIN IDEA IS THAT THIS HAS
THE POTENTIAL TO BE A SIGNIFICANT HEAVY RAIN AND FLASH FLOOD EVENT
FOR MUCH OF OUR REGION. FLASH FLOOD WATCHES CONTINUE FOR ENTIRE
REGION EXCEPT CAPE COD AND THE ISLANDS.
TOTAL WIDESPREAD RAINFALL AMOUNTS THROUGH WEDNESDAY OF 1 TO 3
INCHES ARE EXPECTED ACROSS THE REGION...BUT LOCALIZED 4 TO 6 INCH
AMOUNTS MAY CERTAINLY OCCUR IN THUNDERSTORMS PRODUCING TORRENTIAL
RAINFALL.
