The episode as NWS BTV wrote it up.
Southerly deep layer flow in the atmosphere provided a feed for abundant tropical moisture from the Gulf of Mexico to the northeast. Showers and thunderstorms developed on a daily basis in the summertime heat, and rainfall rates as high as two to three inches in an hour were observed, and flash flooding resulted in several areas where storms remained stationary or repeatedly moved across the same area.

NWS Burlington, VT wrote its last area forecast discussion before the first event at Jul 7, 7:10 PM EST, 56 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE BURLINGTON VT 810 PM EDT SUN JUL 7 2013 .SYNOPSIS... A WARM AND HUMID AIR MASS WILL PERSIST ACROSS THE REGION THROUGH MUCH OF THE WEEK WITH NEAR DAILY CHANCES OF SHOWERS AND THUNDERSTORMS EXPECTED. THE HIGHEST CONCENTRATION OF SHOWERS AND STORMS WILL OCCUR ON MONDAY AND AGAIN ON WEDNESDAY WHEN LOCALLY HEAVY RAINFALL IS POSSIBLE. TEMPERATURES WILL REMAIN ON THE WARM SIDE...WITH HIGHS IN THE 80S AND OVERNIGHT LOWS GENERALLY IN THE 60S. && .NEAR TERM /UNTIL 6 AM MONDAY MORNING/... AS OF 809 PM EDT SUNDAY...LATEST GUIDANCE SHOWING BEST INSTABILITY ACROSS CENTRAL AND SOUTHERN VERMONT AT THIS TIME...AS WELL AS SOUTHERN ESSEX COUNTY IN NEW YORK STATE. THUS...WILL KEEP IN A CHANCE FOR THUNDERSTORMS IN THESE AREAS. FURTHER NORTH...CONDITIONS ARE MORE STABLE...SO HAVE DROPPED THE MENTION OF THUNDERSTORMS ACROSS THE NORTH PORTION OF THE FORECAST AREA OVERNIGHT AND JUST KEPT IN A CHANCE OF SHOWERS. MADE SOME MINOR ADJUSTMENTS TO MIN TEMPERATURES OVERNIGHT. PREVIOUS DISCUSSION FROM 435 PM EDT SUNDAY...A WARM AND HUMID NIGHT EXPECTED ACROSS THE AREA AS DEEPER SUBTROPICAL FLOW HAS PUSHED BACK NORTH AND EAST INTO THE AREA AS EXPECTED. SCATTERED SHOWERS ALSO EXPECTED ON AND OFF THROUGH THE EVENING AND NIGHTTIME HOURS AS HI- RES MODELS AND THIS AFTERNOON'S RAP ANALYSIS SHOWING A WEAK SHORTWAVE MOVING THROUGH THE FLOW ACROSS OUR AREA. MID- LEVEL MOISTURE CONVERGENCE ALSO EVIDENT AS WEAK SURFACE FRONT SAGS SOUTH TO NEAR THE INTL BORDER OVERNIGHT AND STALLS. WITH SUCH WEAK FEATURES QUITE DIFFICULT TO TIME AREAL PLACEMENT AND INTENSITY OF PCPN...BUT PER LATEST LAPS/RUC PROGS WILL ADVERTISE HIGH CHANCE POPS AND CONFINE HIGHER THREAT OF THUNDER AND LOCALLY HEAVY RAINFALL TO OUR SOUTHERN COUNTIES WHERE BEST MLCAPE PROFILES EXIST. AGAIN...A MUGGY NIGHT EXPECTED AS SURFACE DEWPOINTS HOLD IN THE 60S TO AROUND 70. WINDS LIGHT. && .SHORT TERM /6 AM MONDAY MORNING THROUGH TUESDAY NIGHT/... AS OF 435 PM EDT SUNDAY...BY MONDAY STILL LOOKING AT SCATTERED TO WIDESPREAD SHOWERS AND THUNDER ACROSS MUCH OF THE AREA WITH WARM AND MOIST AIRMASS IN PLACE ON THE WESTERN PERIPHERY OF STRONG BERMUDA HIGH PRESSURE. WE'LL ALSO HAVE SOME ADDED IMPETUS FROM A WEAKENING MID-LEVEL SHORTWAVE TROUGH LIFTING OUT OF THE LOWER GREAT LAKES/OHIO VALLEY STATES THROUGH THE DAY. THIS COMBINED WITH LIGHTLY VEERED PBL FLOW...LOWER NCAPE AND DEEP WCD VALUES IN EXCESS OF 11 KFT ALL SUPPORT CONTINUED MENTION OF LOCALLY HEAVY RAINFALL IN THE MORE ROBUST CELLS WHERE EFFICIENT PRECIPITATION LOADING WILL BE LIKELY. WHILE I CAN'T COMPLETELY RULE OUT AN ISOLATED SEVERE CELL...WITH SUCH HIGH WBZ VALUES I'M REALLY NOT EXPECTING ANYTHING OTHER THAN SOME BRIEF GUSTY WINDS AND POSSIBLE SMALL HAIL IN THE STRONGER CORES. HIGHS ON THE SEASONABLY WARM SIDE...76 TO 84 OR CLOSE TO BLENDED BIAS-CORRECTED GUIDANCE. EVENING SHOWERS AND STORMS THEN SLOWLY WANE IN AREAL COVERAGE AND INTENSITY AS WE PROGRESS INTO MONDAY NIGHT AS SHORTWAVE EXITS EAST AND WEAK RIDGING ALONG WITH LAYER OF DRIER MID-LEVEL AIR ADVECTS INTO THE REGION. NO AIRMASS CHANGE...BUT ENOUGH DRYING SUCH THAT MANY AREAS SHOULD TREND DRY BY TUESDAY MORNING. LOWS MAINLY IN THE 60S. THEN MORE UNCERTAINTY AS WE HEAD INTO TUESDAY. FEELING IS TUESDAY SHOULD BE MORE DRY THAN WET GIVEN MID-LEVEL DRY AIR AND WEAK SUBSIDENCE ADVECTING ACROSS THE REGION...BUT EVIDENCE THAT SOME SORT OF LOWER LEVEL MOISTURE BOUNDARY MAY LINGER ACROSS OUR EASTERN COUNTIES. ECMWF MORE ROBUST WITH CHANCES PCPN THAN OTHER SHORT TERM MODELS...BUT WILL DOWNPLAY AT THIS POINT OFFERING JUST SLIGHT TO LOWER CHANCE POPS THROUGH THE DAY AND MAINLY ACROSS VT WHERE SOME WIDELY SCATTERED ACTIVITY MAY OCCUR. HIGHS IN THE LOWER TO MID 80S. BY TUESDAY NIGHT WARM AND HUMID CONDITIONS CONTINUE BUT MAINLY DRY WITH LOSS OF INSOLATION. LOWS TO HOLD ON THE MILD SIDE AND MAINLY IN THE 60S. && .LONG TERM /WEDNESDAY THROUGH SUNDAY/... AS OF 400 PM EDT SUNDAY...ACTIVE WEATHER DAY EXPECTED WEDS/THURS AS POTENT TROF DEVELOPS ACRS THE NORTHERN GREAT LAKES AND SFC COLD FRNT MOVES ACRS OUR CWA. THIS FRNT WL INTERACT WITH MODEST INSTABILITY WITH LIS AROUND -4C AND CAPE VALUES BTWN 1500 TO 2000 J/KG. ALSO...NOTED A RIBBON OF ENHANCED MID LVL WINDS...CREATING DEEP LAYER SHEAR VALUES BTWN 30 AND 40 KNOTS...ESPECIALLY ACRS OUR NORTHERN CWA ON WEDS AFTN. THE AREAL COVERAGE/INTENSITY OF STORMS WL HIGHLY DEPEND UPON AMOUNT OF INSTABILITY/CLRING AND EXACT TRACK OF S/W ENERGY. GIVEN...THE GOOD AGREEMENT IN MODELS WITH SYNOPTIC FEATURES WL CONT TO MENTION HIGH CHC/LOW LIKELY POPS WEDS INTO WEDS NIGHT...STILL A MINOR TIMING DIFFERENCE BTWN THE FASTER GFS AND SLOWER ECMWF. WEAK SUBSIDENCE AND HIGH PRES TRIES TO BUILD ACRS OUR CWA LATE THURS INTO FRIDAY...WITH A BRIEF DRY SPELL POSSIBLE. LOTS OF UNCERTAINTY ASSOCIATED WITH NEXT SYSTEM FRIDAY INTO NEXT WEEKEND...WITH GFS SHOWING MID/UPPER CLOSED CIRCULATION ACRS THE GREAT LAKES RETROGRADING SW TWD TEXAS BY SUNDAY...WHILE THE ECMWF SPLITS THE SYSTEM INTO TWO DISTINCT CLOSED CIRCULATIONS WITH GREATER IMPACT ACRS OUR FA. GIVEN THE UNCERTAINTY IN THE EVOLUTION OF THIS COMPLEX SYNOPTIC PATTERN...WL MENTION CHC POPS NEXT WEEKEND. IF THE ULVL PATTERN VERIFIES ON THE ECMWF AND DEEP TROPICAL MOISTURE IS ADVECTED BACK INTO THE NE CONUS...HYDRO WL NEED TO BE WATCHED CLOSELY...FOR THE POTENTIAL FOR HEAVY RAINFALL. PROGGED 85H TEMPS AHEAD OF BOUNDARY RANGE BTWN 14-16C ON WEDS/THURS...BEFORE COOLING BACK BTWN 10-12C ON FRIDAY...SUPPORTING HIGHS MID/UPPER 80S MID WEEK TO M70S TO L80S BY NEXT FRIDAY. LOWS WL BE MAINLY IN THE U50S MTNS TO M60S VALLEYS. && .AVIATION /00Z MONDAY THROUGH FRIDAY/... THROUGH 00Z TUESDAY...RADAR SHOWS PERSISTENT TS IN THE RUTLAND AREA AND THIS WILL LIKELY CONTINUE NEXT SEVERAL HOURS AS WEAK BOUNDRY REMAINS IN THE AREA. THIS COULD PRODUCE BRIEF IFR CONDITIONS MAINLY DUE TO VIS AT KRUT NEXT SEVERAL HOURS. ANOTHER COMPLEX OF STORMS AND HEAVY RAIN WILL MOVE VERY NEAR TO KRUT AGAIN AFTER 05Z AND TAF REFLECTS MVFR CONDITION BUT COULD BE LOWER IF STORMS HOLD TOGETHER. ELSEWHERE MUCH MORE BENIGN WITH MAINLY VFR EXPECTED OVERNIGHT. A BOUNDARY LIES JUST NORTH OF THE CANADIAN BORDER AND THIS KEEP VCSH NEAR KMSS THROUGH 06Z. EXPECT NE WINDS TO DEVELOP AT KMSS SOON AND CONTINUE UNTIL THE BOUNDARY PUSHES SOUTH. A FEW ISOLATED SHOWERS POSSIBLE AT THE OTHER SITES NEXT FEW HOURS...THEN QUIET OVERNIGHT. OUTLOOK OOZ TUESDAY THROUGH FRIDAY...SCATTERED SHOWERS AND THUNDERSTORMS WL BE POSSIBLE MONDAY AND AGAIN ON WEDS/THURS. THIS ACTIVITY WL HAVE THE POTENTIAL TO PRODUCE BRIEF PERIODS OF MVFR CONDITIONS ALONG WITH LOCALIZED GUSTY WINDS IN AND NEAR STORMS. ALSO...LOOK FOR SOME BR/FOG TO DEVELOP IF SKIES CAN CLR...ESPECIALLY AT MPV/SLK BTWN 07-11Z...WITH GENERALLY SOUTH TO SOUTHWEST WINDS THRU THE PERIOD. && .HYDROLOGY... AS OF 435 PM EDT SUNDAY... LOCALLY HEAVY RAINFALL WILL REMAIN POSSIBLE ACROSS THE SOUTHERN PORTIONS OF THE FORECAST AREA THIS EVENING...AND ACROSS THE ENTIRE AREA ON MONDAY. WHILE WIDESPREAD OR ORGANIZED AREAS OF FLASH FLOODING ARE NOT EXPECTED...WCD VALUES WILL REMAIN QUITE HIGH ALONG WITH HIGH COLUMNAR MOISTURE PROFILES. THUS POINT TOTALS IN EXCESS OF ONE INCH IN AN HOUR OR LESS WILL BE POSSIBLE...WHICH CHOULD LEAD TO LOCALIZED HYDROLOGICAL CONCERNS...ESPECIALLY ON MONDAY WHEN BOUNDARY LAYER FLOW WILL BE QUITE LIGHT BELOW 850 MB. && .EQUIPMENT... AS OF 415 AM EDT SUNDAY...THE KTYX RADAR IS DOWN UNTIL FURTHER NOTICE.
