The episode as NWS BOX wrote it up.
An upper level disturbance moved over southern New England bringing showers and thunderstorms to the region. Precipitable water values over two inches indicated a very moist atmosphere; in addition, weak winds at the mid levels resulted in very slow moving storms. Both of these things led to torrential rainfall and flash flooding. This is the second day in a row that parts of Kent County received between three and four inches of rain.
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 Sep 1, 3:25 AM EST, 25 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE TAUNTON MA 425 AM EDT SUN SEP 1 2013 .SYNOPSIS... A STALLED FRONTAL BOUNDARY STRETCHING FROM NEW YORK STATE INTO NEW ENGLAND WILL RESULT IN SCATTERED SHOWERS AND THUNDERSTORMS WITH HEAVY RAIN AT TIMES TODAY THROUGH TUESDAY. SHOWERS AND THUNDERSTORMS MAY BECOME MORE WIDESPREAD LATE TONIGHT INTO MONDAY AND EARLY TUESDAY AS A COLD FRONT MOVES ACROSS THE REGION. DRIER...COOLER AND MUCH LESS HUMID WEATHER ARRIVES MIDDLE OF NEXT WEEK. && .NEAR TERM /UNTIL 6 PM THIS EVENING/... THIS MORNING... CONVECTION CONTINUES TO FIRE EARLY THIS MORNING ACROSS CENTRAL MA AND EASTERN CT IN RESPONSE TO A WEAK MID LEVEL SHORT WAVE OVER NY/PA AND NJ. ATMOSPHERE OVER SOUTHERN NEW ENGLAND IS FAIRLY UNSTABLE FOR THIS TIME OF NIGHT/MORNING WITH OBSERVED MU CAPES 1000-1500J/KG AND MID LEVEL LAPSE RATES AROUND 6C/KM. SURFACE DEW PTS IN THE L70S CONTRIBUTING TO THIS INSTABILITY. MAIN CONCERN WITH ANY STRONG TSTMS EARLY THIS MORNING WILL BE TORRENTIAL DOWNPOURS AND FLOOD POTENTIAL...AS PWATS ARE AROUND 2 INCHES AND K INDICES NEAR 40! WEAK WINDS ALOFT WILL YIELD SLOW MOVING STORMS INCREASING THE RISK OF LOCALIZED FLOODING. AS FOR THE RISK OF STRONG TO SEVERE WINDS WITH STORMS...RISK IS VERY LOW GIVEN THE WEAK WINDS ALOFT AND STORM STRUCTURE/STORM CORES HAVE BEEN VERY NARROW. HOWEVER CAN/T COMPLETELY RULE OUT AN ISOLATED GUSTY TSTM GIVEN INSTABILITY PARAMETERS SUPPORT ISOLATED STRONG UPDRAFT/DOWNDRAFT POTENTIAL. GOOD MODEL AGREEMENT THAT GREATEST INSTABILITY WILL DRIFT SE THIS MORNING. THUS EXPECTING CONVECTION TO TRANSLATE EAST SOUTHEAST INTO RI AND EASTERN MA ALONG WITH SOME REDEVELOPMENT. AFTER 12Z BEST INSTABILITY SHOULD BEGIN TO MOVE OFFSHORE. THIS SHOULD PROVIDE A LULL IN THE ACTIVITY BEFORE NEW CONVECTION FIRES THIS AFTERNOON. THIS AFTERNOON... LOW CONFIDENCE FORECAST FOR THIS AFTERNOON GIVEN THE WEAK SYNOPTIC SCALE FORCING ENVIRONMENT. THERE SHOULD BE A LULL IN THE CONVECTION LATER THIS MORNING AS A LEAD SHORT WAVE /ALBEIT WEAK/ MOVES OFFSHORE 12Z-15Z. THEREAFTER DIFFICULT TO FIND A TRIGGER FOR NEW CONVECTION THIS AFTERNOON. HOWEVER IT WON'T TAKE MUCH TO GENERATE TSTMS AS ALL MODEL GUIDANCE INCLUDING THE GEFS AND ECMWF OFFERING CAPES 1200- 1800J/KG BY 18Z. THE WEAK MOIST CYCLONIC FLOW ALOFT COMBINED WITH ANY LEFTOVER BOUNDARIES FROM CONVECTION EARLY THIS MORNING MAY BE SUFFICIENT TO INITIATE NEW CONVECTION. IF SEABREEZE BOUNDARIES DEVELOP THAT COULD BECOME A FOCUS FOR CONVECTION. SO CONFIDENCE IS MODERATE TO HIGH ON NEW CONVECTION FIRING THIS AFTERNOON BUT LOWER CONFIDENCE ON AREAL COVERAGE GIVEN WEAK SYNOPTIC SCALE FORCING ENVIRONMENT. MAIN HAZARD WITH STORMS WILL BE TORRENTIAL DOWNPOURS GIVEN HIGH PWAT AIRMASS /NEAR 2 INCHES/ AND WEAK WINDS ALOFT YIELDING SLOW MOVING STORMS. THUS RISK FOR FLASH FLOODING EXIST BUT CONFIDENCE LOW ON AREAL COVERAGE. THEREFORE HELD OFF ON ISSUING A FLASH FLOOD WATCH. LATER SHIFTS WILL NEED TO REEVALUATE. ANOTHER WARM AND MUGGY DAY WITH DEW PTS IN THE U60S AND L70S. JUST LIKE YESTERDAY AMOUNT OF SUNSHINE REMAINS UNCERTAIN. NEVERTHELESS GIVEN THE WARM START THIS MORNING /LOW TO MID 70S/ ONLY A FEW HOURS OF SUNSHINE WILL KICK TEMPS INTO THE LOW TO MID 80S. && .SHORT TERM /6 PM THIS EVENING THROUGH 6 PM MONDAY/... TONIGHT AND MONDAY... HIGHER AMPLITUDE SHORT WAVE MOVES ACROSS THE REGION. THIS WILL PROVIDE STRONGER SYNOPTIC SCALE LIFT ALONG WITH INCREASING WIND FIELDS ALOFT. THIS SHOULD YIELD MORE WIDESPREAD AND ORGANIZED CONVECTION. THEREFORE LIKELY POPS FROM THE GFS AND NAM SEEM REASONABLE. HEAVY DOWNPOURS LIKELY WITH PWATS ABOUT +2 STD FROM CLIMO. LOW RISK OF A FEW STORMS WITH STRONG WINDS AS WIND FIELDS ALOFT INCREASE. THIS WILL HINGE ON MAGNITUDE OF INSTABILITY WHICH IS UNCERTAIN AT THIS TIME RANGE GIVEN POTENTIAL CLOUD COVER FROM CONVECTION TONIGHT INTO MON MORNING. WARM AND HUMID CONDITIONS CONTINUE AS SOUTHERN NEW ENGLAND REMAINS IN THE WARM SECTOR. && .LONG TERM /MONDAY NIGHT THROUGH SATURDAY/... HIGHLIGHTS... * HUMID WITH SHOWERS AND THUNDERSTORMS ON TUESDAY * SEASONABLE AND LESS HUMID MID-WEEK * DRY AND COOLER FOR THE END OF THE WEEK CONFIDENCE LEVEL/MODEL GUIDANCE... MODERATE CONFIDENCE IN OVERALL FORECAST. CONTINUE TO HAVE INCREASING CONFIDENCE FOR THE TEMPERATURE ASPECT IN THE FORECAST. MODERATE CONFIDENCE IN TIMING OF PRECIPITATION WITH HIGH CONFIDENCE THAT PRECIP WILL OCCUR ON TUESDAY. THE LATEST MODEL GUIDANCE SHOWS RELATIVELY GOOD AGREEMENT WITH THE LARGE-SCALE FLOW THROUGH THE UPCOMING MEDIUM RANGE PERIOD. A BROAD TROUGH ACROSS THE GREAT LAKES AND INTO THE NORTHEAST WILL BE ACCOMPANIED BY OCCASIONAL COLD FRONTAL PASSAGES AND BRIEF PERIODS OF RAINFALL AND COOLER TEMPERATURES. SEEMS THIS FLOW WILL BE PERSISTENT FOR SOMETIME AS MODELS ARE NOT INDICATING A PATTERN CHANGE ANYTIME SOON. DETAILS... TUESDAY... CONVECTION WILL CONTINUE OVERNIGHT AS ELEVATED INSTABILITY REMAINS ACROSS THE REGION AND SHOWALTERS DROP TO -4. THIS COMBINED WITH DEWS ABOVE 70F WILL ALLOW FOR STORMS TO CONTINUE TO REGENERATE . THE MAIN FORCING MECHANISMS...THE COLD FRONT...WILL MOVE THROUGH SOUTHERN NEW ENGLAND ON TUESDAY. MAIN QUESTION IS THE TIMING. MODELS HAVE SHIFTED MORE TOWARDS A SLOWER SOLUTION THEN COMPARED TO LAST NIGHT. THEREFORE BELIEVE THAT THERE IS A CHANCE FOR SHOWERS AND THUNDERSTORMS TO DEVELOP ESP ACROSS THE EASTERN HALF OF THE REGION. HEAVY SHOWERS ARE POSSIBLE WITH MAIN CONCERN BEING NUISANCE FLOODING AS PWAT VALUES WILL BE 1.5 TO 2 INCHES. MODERATE CONFIDENCE IN STRONG/SEVERE STORMS AS SHEAR VALUES INCREASE BETWEEN 30-40KTS. INSTABILITY SHOULD REACH AROUND 1000-2000 J/KG AS DEWPOINTS WILL BE HIGH...HOWEVER LIMITING FACTOR WILL BE CLOUD COVER. WILL NEED TO CONTINUE TO MONITOR. WEDNESDAY... COLD FRONT WILL BE WELL OFFSHORE BY WEDNESDAY. WEAK SURFACE HIGH PRESSURE WILL TRY TO PUSH INTO THE REGION ALLOWING FOR DRY WEATHER AND COOLER DEWPOINTS. THURSDAY THROUGH SATURDAY... MODELS ARE INDICATING A POLAR FRONT WILL MOVE THROUGH ON THURSDAY BRINGING SOME ISOLATED/SCATTERED SHOWERS. HAVE A LOWER CONFIDENCE AS THERE IS A GOOD AMOUNT OF DRY AIR ACROSS THE AREA. BEHIND THIS FRONT IS A MORE FALL LIKE AIRMASS BRINGING OVERNIGHT LOWS IN THE 40S AND HIGHS ONLY IN THE 60S WITH THURSDAY NIGHT/FRIDAY MORNING HAVING THE BEST SHOT FOR THE COOLEST TEMPS. HIGH PRESSURE FILTERS IN ON FRIDAY WITH TEMPS MODERATING BACK UP TO AVERAGE BY FRIDAY AND SATURDAY. && .AVIATION /08Z SUNDAY THROUGH THURSDAY/... FORECASTER CONFIDENCE LEVELS... LOW...LESS THAN 30 PERCENT. MODERATE...30 TO 60 PERCENT. HIGH...GREATER THAN 60 PERCENT. OVERVIEW...LOW CONFIDENCE ON ALL ASPECTS OF FORECAST. TAFS WERE DERIVED FROM AN EVEN BLEND OF GFS AND NAM MODELS. TODAY...TSTMS OVER WESTERN AND CENTRAL PORTIONS OF MA/CT WILL MOVE SOUTHEAST TOWARD RI AND SOUTHEAST MA 06Z-12Z...THEN OFFSHORE AFTER 12Z. A BRIEF LULL BEFORE NEW TSTMS FIRE AFT 15Z. LOW CONFIDENCE ON EXACT AREAL COVERAGE OF TSTMS. MAIN THREAT WILL BE VERY HEAVY RAIN WITH ANY GIVEN STORM. IFR CONDITIONS THIS MORNING SHOULD LIFT TO MVFR AND POSSIBLY VFR THIS AFTERNOON...BUT BRIEFLY BACK TO MVFR IN TSTMS. TONIGHT...MORE TSTMS EXPECTED BUT LOW CONFIDENCE ON AREAL COVERAGE. AGAIN MAIN THREAT WILL BE HEAVY RAIN. MODERATE TO HIGH PROBABILITY OF IFR ACROSS RI AND EASTERN MA. MONDAY...SHOWERS AND TSTMS COULD BE WIDESPREAD WITH HEAVY RAIN THE MAIN HAZARD. IFR IN THE MORNING MAY LIFT TO MVFR AND PERHAPS VFR DURING THE AFTERNOON. KBOS TERMINAL...TSTMS OVER WESTERN-CENTRAL MA AND CT SHOULD SHIFT SOUTHEAST INTO RI AND SOUTHEAST MA TOWARD SUNRISE. LOGAN WILL BE ON THE NW FRINGE OF TSTMS. AFTER 12Z TSTMS WILL BEGIN MOVING OFFSHORE. HOWEVER NEW TSTMS WILL LIKELY DEVELOP BY 15Z-16Z. HEAVY RAIN THE MAIN HAZARD WITH ANY STORM. KBDL TERMINAL...NUMEROUS TSTMS THROUGH 08Z-09Z AND THEN SHOULD SHIFT SE INTO RI. HOWEVER NEW TSTMS WILL LIKELY DEVELOP BY 15Z- 16Z. HEAVY RAIN THE MAIN HAZARD. OUTLOOK...MONDAY NIGHT THROUGH FRIDAY... MONDAY NIGHT-TUESDAY...LOW CONFIDENCE MAINLY FOR TIMING. MVFR CONDITIONS WITH LOCALIZED IFR IN SHOWERS/TSTMS. PERIODS OF HEAVY RAINFALL WILL REDUCE VSBYS AS WELL. WEDNESDAY-FRIDAY...HIGH CONFIDENCE. VFR. && .MARINE... FORECASTER CONFIDENCE LEVELS... LOW...LESS THAN 30 PERCENT. MODERATE...30 TO 60 PERCENT. HIGH...GREATER THAN 60 PERCENT. TODAY... TSTMS WITH VERY HEAVY RAIN AND A FEW STRONGER STORMS WITH SMALL HAIL LIKELY EARLY THIS MORNING ACROSS THE SOUTH COASTAL WATERS. STORMS WILL BEGIN TO MOVE OFFSHORE AFTER 12Z. HOWEVER NEW TSTM WILL LIKELY FORM OVER LAND THIS AFTERNOON. HEAVY RAIN/POOR VSBY MAIN THREAT THIS AFTERNOON. MODEST SSW WIND AND WAVES CONTINUE. TONIGHT AND MONDAY... TSTMS MAY BECOME MORE WIDESPREAD/NUMEROUS THIS FORECAST PERIOD. HEAVY RAIN AND GUSTY WINDS LIKELY. SSW WINDS AND WAVES CONTINUE. REDUCED VSBY IN HEAVY RAIN AND PATCHY FOG. OUTLOOK...MONDAY NIGHT THROUGH FRIDAY... EXPECT SEAS TO REMAIN MOSTLY BELOW SCA THRESHOLDS THROUGH THE PERIOD. LOW PROB FOR A FEW GUSTS TO 25 KTS ARE POSSIBLE TUES AFTERNOON BEHIND THE COLD FRONT.
