The episode as NWS BOX wrote it up.
High pressure moved offshore allowing the environment to become more unstable and allowing afternoon heating to initiate thunderstorms. A few of these storms became severe producing damaging winds along with lightning.

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE TAUNTON MA
440 PM EDT WED JUL 2 2014
.SYNOPSIS...
VERY HUMID CONDITIONS WILL CONTINUE THROUGH THE END OF THE WEEK.
STRONG THUNDERSTORMS WILL LINGER OVER THE INTERIOR THROUGH THIS
EVENING. MORE WIDESPREAD SHOWERS/THUNDERSTORMS WITH LOCALLY HEAVY
RAINFALL ARE EXPECTED THURSDAY AND FRIDAY. TROPICAL STORM ARTHUR
WILL PASS SOUTHEAST OF OUR REGION FRIDAY NIGHT INTO
SATURDAY...PERHAPS HAVING A SIGNIFICANT IMPACT ON THE MARINE
COMMUNITY. HIGH PRESSURE THEN BUILDS OVER NEW ENGLAND WITH FAIR
DRY WEATHER FOR THE WEEKEND.
&&
.NEAR TERM /UNTIL 6 AM THURSDAY MORNING/...
THROUGH 02Z/10 PM...
A SEVERE THUNDERSTORM WATCH CONTINUES FOR MUCH OF THE INTERIOR
THROUGH THE EVENING. A FLASH FLOOD WATCH CONTINUES THROUGH
MIDNIGHT FOR THE CT VALLEY AND CENTRAL HILLS. CONVECTION IS
ONGOING IN WESTERN MASS AND SOUTHERN NH...AND EXTENDS SOUTHWEST TO
EASTERN PA. THIS IS ALONG/AHEAD OF A SURFACE LOW AND TROUGH THAT
WAS OVER THE CATSKILLS AT MID AFTERNOON. THE SURFACE LOW WILL MOVE
EAST AND PUSH ALONG THE CONVECTION. THIS WILL MOVE SHOWERS/STORMS
FARTHER EAST THIS EVENING AND EARLY NIGHT. NORTHERN CT/CENTRAL
MASS/MERRIMACK VALLEY WOULD BE MOST AT RISK FROM THESE STORMS.
REST OF TONIGHT...
AFTER SUNSET THE STORMS SHOULD DIMINISH IN COVERAGE AND INTENSITY.
COLD FRONT IN THE GREAT LAKES WILL MOVE EAST...BUT UPPER
SHORTWAVE MOVES UP THE FRONT AND SHOULD SLOW DOWN ITS FORWARD
PROGRESS. NO CHANGE IN THE AIRMASS SO CONTINUED WARM AND HUMID
THROUGH THE NIGHT. WITH WET GROUND IN THE NORTHWEST AND HIGH
DEWPOINT AIR OVER MOST LOCATIONS...EXPECT AREAS OF FOG AND LOW
CLOUDS. TEMPS SHOULD BE NEAR DEWPOINT...IN THE UPPER 60S TO MID
70S.
&&
.SHORT TERM /6 AM THURSDAY MORNING THROUGH THURSDAY NIGHT/...
THURSDAY AND THURSDAY NIGHT...
TS ARTHUR WILL BE MOVING UP THE EAST COAST EMBEDDED IN A FLOW OF
VERY HUMID AIR. PRECIP WATER VALUES BETWEEN 2 AND 2.25 INCHES
ACROSS MUCH OF SOUTHERN NEW ENGLAND WITH FOCUS ON EASTERN
MASS/RI/CONNECTICUT. THE RIGHT ENTRANCE REGION OF THE UPPER JET
WILL APPROACH DURING THE MORNING AND MOVE OVERHEAD IN THE
AFTERNOON/EVENING. SURFACE BASED CAPE WILL AGAIN BE AROUND 2000
J/KG WITH AN AXIS FROM NE MASS TO SW CT. WIND FIELDS WILL BE
MARGINAL WITH 25 KNOTS AT 850 MB BUT 35-40 KNOTS AT 500 MB. AT
THE VERY LEAST...THIS SUGGESTS SHOWERS/TSTMS WITH HEAVY DOWNPOURS.
BUT THERE IS SUFFICIENT INSTABILITY AND MARGINAL WIND TO CONSIDER
ANOTHER ROUND OF DAMAGING WIND/LARGE HAIL FROM TSTMS. WITH THE
AXIS OF INSTABILITY FARTHER EAST...THE TSTM THREAT WILL EXPAND
ACROSS RI AND EASTERN MASS.
THESE SUPPORTING CONDITIONS CONTINUE INTO THURSDAY NIGHT. THERE
ARE SIGNS OF THE AXIS OF SUPPORT SHIFTING WEST IN RESPONSE TO THE
APPROACHING RIGHT ENTRANCE REGION OF THE UPPER JET. BUT WE WILL
CONTINUE A CHANCE OF SHOWERS/TSTMS AT NIGHT.
CLOUD COVER AND MORE NUMEROUS SHOWERS/TSTMS WILL KEEP MAX TEMPS
MOSTLY IN THE LOW TO MID 80S WITH UPPER 70S ALONG THE S COAST.
&&
.LONG TERM /FRIDAY THROUGH WEDNESDAY/...
HIGHLIGHTS...
* POTENTIAL FOR PERIODS OF HEAVY RAIN/AND POSSIBLE FLASH FLOODING
THRU FRI
* TROPICAL STORM ARTHUR MAY PASS SOUTHEAST OF US FRI NIGHT
* HIGH PRESSURE RETURNS FOR THE WEEKEND
* INCREASING HEAT AND HUMIDITY EARLY NEXT WEEK
THERE IS STILL SOME UNCERTAINTY IN THE FIRST PART OF THE LONG
TERM DEPENDENT ON THE TRACK OF ARTHUR. DETERMINISTIC MODELS HAVE
DISAGREEMENT AS TO HOW CLOSE TO THE SNE COASTLINE OR HOW FAR
OFFSHORE ARTHUR IS...AS IT TRACKES NORTHEASTWARD ON FRIDAY NIGHT
AND SATURDAY MORNING. THE OFFICIAL NHC TRACK HAS ARTHUR TRACKING
NEAR THE 40N 70W BENCHMARK DURING FRIDAY NIGHT. FOR POINT OF
CLOSEST PASS FOR THE CENTER OF ARTHUR...THE CONE OF UNCERTAINTY
STRETCHES FROM NANTUCKET/CHATHAM TO WELL OFFSHORE. ALTHOUGH THE
GFS IS THE FARTHEST WEST OF THE DETERMINISTIC SUITE...IT IS NOT
OUTSIDE OF THE NHC CONE OF UNCERTAINTY EITHER. DETERMINISTIC 12Z
ECMWF IS CLOSE TO NHC MOST PROBABLE TRACK/TIMING NEAR OUR AREA.
FIRST LOOKING TO FRIDAY. ARTHUR WILL STILL BE APPROACHING FROM THE
SW. MODELS ARE IN CONSENSUS THAT THE NE-SW ORIENTED COLD FRONT WILL
BE IN OUR CWA DURING THE DAY. IN ADDITION...A DEEP LAYER S TO SW
FLOW WILL BE PUMPING TROPICAL MOISTURE NORTHWARD FROM ARTHUR INTO
OUR AREA. WE ARE EXPECTED TO BE IN THE RIGHT REAR QUADRANT OF THE
UPPER JET FOR A PERIOD OF TIME. THE GREATEST CHANCE FOR SHOWERS
AND SOME TSTMS WILL BE ALONG AND EAST OF THE COLD FRONT. SO IN THE
WESTERN PORTION OF OUR CWA...POPS WILL START OUT AT CHANCE.
ELSEWHERE...STARTING OUT WITH LIKELY POPS FOR SHOWERS AND CHANCE
FOR THUNDER...WITH LOCALLY HEAVY RAIN EXPECTED. LOCALIZED FLASH
FLOODING IS A THREAT...2 TO 3 INCHES OF RAIN IN AN HOUR COULD
CAUSE FLASH FLOODING...EXCEPT ONLY 1 TO 2 INCHES OF RAIN IN AN
HOUR IS NEEDED FOR MANY URBAN CENTERS TO CAUSE URBAN FLASH
FLOODING. THE BEST CHANCE FOR HEAVY RAINFALL WILL BE OVER
EASTERN MA AND RI. USING NERFC QPF. WIND STRENGTH FOR THE CAPE
AND ISLANDS AND SOUTHERN COASTAL WATERS COULD BE ENHANCED BY
APPROACH OF ARTHUR AS FRIDAY PROGRESSES. THE OVERALL PROBABILITY
OF TROPICAL STORM FORCE WINDS BEING ATTAINED BY ARTHUR IN SOUTHERN
NEW ENGLAND ARE AVAILABLE ON THE NATIONAL HURRICANE CENTER
WEBSITE. IN ADDITION...FOR BOTH FRI AND FRI NIGHT POINT AND CLICK
GRAPHICS FROM HTTP:WEATHER.GOV/BOSTON AND THE TRADITIONAL ZFPBOX
AND CWFBOX CONTAIN THIS POSSIBILITY.
FRIDAY NIGHT...ARTHUR LIKELY MAKES ITS CLOSEST APPROACH TO SOUTHERN
NEW ENGLAND DURING THIS TIMEFRAME. WIND STRENGTH FOR SOUTHEAST MA
AND RI AS WELL AS THE COASTAL WATERS COULD BE ENHANCED BY THE
APPROACH OF ARTHUR. THE HIGHEST LIKELIHOOD FOR PRECIPITATION BASED
ON THE CURRENT FORECAST TRACK IS ACROSS EASTERN MASSACHUSETTS AND
RHODE ISLAND SO WILL KEEP HIGHEST POPS IN THIS REGION FOR FRI NIGHT.
LOCALLY HEAVY RAINFALL STILL POSSIBLE IN THAT AREA...SO
LOCALIZED/URBAN FLASH FLOODING WOULD BE A THREAT TO START. NERFC/HPC
QPF.
SATURDAY AND SUNDAY...BY 12Z SATURDAY CENTER OF ARTHUR SHOULD BE
TRACKING WELL NE OF OUR AREA...SO ONLY SLIGHT CHANCE TO LOW CHANCE
POPS FAR EASTERN MA TO START OUT THE DAY. THEN HIGH PRESSURE BUILDS
IN BEHIND ARTHUR BRINGING MOSTLY SUNNY SKIES. HIGH PRESSURE REMAINS
IN CONTROL OVER OUR AREA THRU SUNDAY.
MONDAY AND TUESDAY...EXPECT INCREASING HEAT AND HUMIDITY AS HIGH
CENTER MOVES OFFSHORE AND SOUTHWESTERLY SURFACE WINDS RETURN. THERE
IS POTENTIAL FOR SHOWERS AND THUNDERSTORMS TUESDAY WITH THE APPROACH
AND POTENTIAL PASSAGE OF A COLD FRONT.
POTENTIALLY DRY AND IN BETWEEN SYSTEMS ON WEDNESDAY...WITH BRIEF
VISIT OF HIGH PRESSURE.
&&
.AVIATION /21Z WEDNESDAY THROUGH MONDAY/...
FORECASTER CONFIDENCE LEVELS...
LOW...LESS THAN 30 PERCENT.
MODERATE...30 TO 60 PERCENT.
HIGH...GREATER THAN 60 PERCENT.
THIS AFTERNOON/EVENING...MODERATE CONFIDENCE. VFR WITH LOCAL MVFR
CIGS/IFR VSBYS IN THUNDERSTORMS MAINLY ALONG/NORTH OF A HARTFORD-
WORCESTER-GLOUCESTER LINE. SOUTHWEST WINDS GUSTING NEAR 20 KNOTS.
HEAVY DOWNPOURS IN ANY TSTMS. TSTMS DIMINISH 9-10 PM.
TONIGHT...MODERATE CONFIDENCE. AREAS OF MVFR/IFR AS STRATUS AND
PATCHY FOG REDEVELOPS. DIMINISHING COVERAGE OF SHOWERS/TSTMS.
THURSDAY AND THURSDAY NIGHT...MODERATE CONFIDENCE. MORNING
MVFR/IFR IN FOG WILL IMPROVE TO VFR...BUT SHOWERS/TSTMS ARE
EXPECTED TO DEVELOP WITH MVFR/IFR CIGS/VSBYS IN ANY TSTMS. HEAVY
DOWNPOURS IN ANY TSTMS.
KBOS TAF...MODERATE CONFIDENCE IN TAF. THERE IS A LOW PROB OF IFR
STRATUS LATE TONIGHT. TSTMS LIKELY THURSDAY WITH MVFR/IFR
CIGS/VSBYS.
KBDL TAF...MODERATE CONFIDENCE IN TAF. TSTMS LATE AFTERNOON WITH
BRIEF MVFR/IFR CIGS/VSBYS. IFR STRATUS POSSIBLE LATE TONIGHT. MORE
TSTMS POSSIBLE ON THURSDAY WITH MVFR/IFR CIGS/VSBYS.
OUTLOOK...FRIDAY THROUGH SUNDAY...
FRIDAY...LOW CONFIDENCE. MVFR/IFR CONDITIONS LIKELY IN LOW
CLOUDS...FOG...AND HEAVY RAIN. ISOLATED THUNDER POSSIBLE.

.MARINE...
FORECASTER CONFIDENCE LEVELS...
LOW...LESS THAN 30 PERCENT.
MODERATE...30 TO 60 PERCENT.
HIGH...GREATER THAN 60 PERCENT.
TONIGHT THROUGH THURSDAY NIGHT...HIGH CONFIDENCE.
EXPECT MAINLY SW WINDS 10-20 KT THROUGH THE PERIOD BUT CANT RULE
OUT A FEW HIGHER GUSTS APPROACHING SCA OVER NEARSHORE WATERS. ALSO
STRONGER GUSTS POSSIBLE NEAR ANY THUNDERSTORMS. SEAS WILL BE LESS
THAN 5 FEET TONIGHT. BUT THE STEADY SOUTHWEST WIND WILL SLOWLY
BUILD SEAS THURSDAY WITH 5 FOOT SEAS ON THE OUTER WATERS AND
POSSIBLY RI SOUND THURSDAY AFTERNOON AND NIGHT. AREAS OF FOG MAY
REDUCE VSBYS TONIGHT AND THURSDAY MORNING. SCATTTERED SHOWERS/TSTMS
EXPECTED THURSDAY AND THURSDAY NIGHT.
OUTLOOK...FRIDAY THROUGH MONDAY...
FRIDAY...MODERATE CONFIDENCE. PERSISTENT LONG SOUTH TO SOUTHWEST
FETCH AS WELL AS APPROACH OF ARTHUR LATE IN THE DAY WILL LIKELY
YIELD SCA SEAS...BETWEEN 3 AND 6 FT...ACROSS MOST OF THE OUTER
WATERS. THERE IS A RISK OF FOG...PARTICULARLY DURING THE LATE
NIGHT/EARLY MORNING HOURS WITH DEEP LOW LEVEL MOISTURE IN PLACE.
IN ADDITION...HEAVY RAIN IS POSSIBLE AT TIMES.
FRIDAY NIGHT AND SATURDAY...LOW CONFIDENCE. TROPICAL STORM ARTHUR
IS FORECAST TO PASS NEAR THE BENCHMARK FRIDAY NIGHT. THIS WILL
BRING A PERIOD OF HIGH SEAS AND STRONG WINDS TO THE SOUTHEAST
WATERS FRI NIGHT POSSIBLY INTO EARLY SATURDAY. THIS SYSTEM COULD
HAVE A SIGNIFICANT IMPACT ON THE MARINE COMMUNITY. WINDS AND SEAS
DIMINISH SLOWLY SATURDAY AFTERNOON AS ARTHUR MOVES AWAY FROM THE
REGION.
SATURDAY NIGHT AND SUNDAY...MODERATE CONFIDENCE. QUIET BOATING
WEATHER. LOW PROBABILITY OF 5 FOOT SEAS ON THE OUTER WATERS LATE
SUNDAY.
MONDAY...HIGH PRESSURE CENTER MOVES EAST OF THE WATERS...WITH
INCREASING SW FLOW. POTENTIAL SCA CONDITIONS /WINDS AND SEAS/ DURING
THIS TIMEFRAME.
&&
.HYDROLOGY...
WITH THE ATMOSPHERE AS JUICY AS IT IS...AND WITH NO SIGNIFICANT
CHANGE EXPECTED THROUGH FRIDAY NIGHT...THERE IS THE POTENTIAL FOR
SHOWERS AND THUNDERSTORMS PRODUCING HEAVY RAINFALL THROUGH THIS
TIME. THIS WILL MEAN A CHANCE FOR URBAN AND SMALL STREAM FLASH
FLOODING. RIVERS AND STREAMS ARE GENERALLY AT NORMAL LEVELS FOR
THIS TIME OF YEAR...EXCEPT BELOW NORMAL ACROSS EASTERN MA AND
NORTHERN RI. BECAUSE OF THIS LARGER TRIBUTARY AND MAINSTEM RIVERS
WOULD BE MORE DIFFICULT TO FLOOD.
A FLASH FLOOD WATCH REMAINS IN EFFECT THROUGH MIDNIGHT IN RESPONSE
TO TODAY/S CONVECTION. ADDITIONAL FLASH FLOOD WATCHES WILL LIKELY
BE NEEDED ON THURSDAY AND FRIDAY.
