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. Soils remained very moist from previous heavy rainfall that began in late May and continued through early July. Showers and thunderstorms developed in the summertime heat, and flash flooding developed from excessive runoff.

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE BURLINGTON VT
354 PM EDT THU JUL 18 2013
.SYNOPSIS...
AN ACTIVE WEATHER PATTERN WILL CONTINUE ACROSS THE NORTH COUNTRY
WITH SCATTERED SHOWERS AND THUNDERSTORMS... ALONG WITH HOT AND
HUMID CONDITIONS THROUGH THE END OF THE WEEK. SOME THUNDERSTORMS
COULD BECOME STRONG TO LOCALLY SEVERE TONIGHT AND FRIDAY. A COLD
FRONT WILL MOVE THROUGH ON SATURDAY BRINGING MUCH DRIER AND
COOLER AIR FOR SUNDAY AND MONDAY.
&&
.NEAR TERM /UNTIL 6 AM FRIDAY MORNING/...
AS OF 354 PM EDT THURSDAY...MAIN FOCUS FOR THE LATE AFTERNOON AND
EVENING WILL BE FOR STRONG TO LOCALLY SEVERE THUNDERSTORMS. STRONG
TO LOCALLY SEVERE THUNDERSTORMS HAVE BEEN MAINLY FOCUSED ACROSS
CENTRAL VERMONT AND ACROSS THE SAINT LAWRENCE VALLEY THIS
AFTERNOON. THE AIRMASS REMAINS UNSTABLE WITH RAP-BASED LIFTED
INDICES OF -6 TO -8 AND SBCAPES OF 2500-3500 J/KG COMMON ACROSS
THE NORTH COUNTRY. SHOWERS AND THUNDERSTORMS WILL CONTINUE TO MOVE
EASTWARD/NORTHEASTWARD THIS EVENING AS SFC WARM FRONT NOW OVER THE
SOUTHERN GREAT LAKES LIFTS NORTHEASTWARD TONIGHT AND OVERNIGHT.
STORMS MAY CONTINUE TO BE STRONG THROUGH MID- EVENING BEFORE
COVERAGE/INTENSITY BEGINS TO WANE. MAINTAINED ENHANCED WORDING FOR
GUSTY WIDNS & HEAVY RAINFALL THROUGH 10PM WITH DECREASING POPS
THEREAFTER. NORTHWARD ADVECTION OF 850 MB TEMPERATURES OF 16-18C
SHOULD ALLOW FOR TONIGHT'S LOWS TO BE A FEW DEGREES WARMER THAN
LAST NIGHT. STILL QUITE MUGGY WITH LOWS IN THE MID 60S TO LOWER
70S IN THE VALLEYS.
&&
.SHORT TERM /6 AM FRIDAY MORNING THROUGH SATURDAY NIGHT/...
AS OF 354 PM EDT THURSDAY...PERIOD OF ACTIVE WEATHER CONTINUES
THIS PERIOD WITH STRONG THUNDERSTORMS AND HEAT FRIDAY...WITH A
CONTINUED THREAT OF SHOWERS AND THUNDERSTORMS /THOUGH NOT LIKELY
TO BE QUITE AS STRONG/ INTO SATURDAY.
WITH THE WARM FRONT LIFTING INTO SOUTHERN QUEBEC EARLY FRIDAY...THE
NORTH COUNTRY WILL BE UNDER SOUTHWEST FLOW ALOFT AND IN THE WARM
SECTOR WITH A COLD FRONT POSITIONED OVER CENTRAL QUEBEC/ONTARIO.
THIS BOUNDARY WILL SLOWLY SAG SOUTHWARD TOWARD THE INTERNATIONAL
BORDER INTO WHAT IS EXPECTED TO BE A HIGHLY UNSTABLE AIRMASS
/AFTERNOON CAPES IN EXCESS OF 2000 J/KG/. SO LOOKING AT POTENTIAL
DEVELOPMENT OF SCATTERED STRONG THUNDERSTORMS DURING THE AFTERNOON
ONCE AGAIN...AND HAVE KEPT GUSTY WINDS & HEAVY RAINFALL WORDING WITH
THUNDERSTORMS. THOUGH THE SOUTHWEST FLOW ALOFT WILL KEEP DEEP-LAYER
SHEAR IN THE 40-50KT RANGE AND FAVOR STRONG CONVECTION...IT MAY
LIMIT MORE ROBUST CONVERGENCE. FRIDAY WILL LIKELY BE THE WARMEST
STRETCH OF THE PERIOD WITH HIGHS IN THE UPPER 80S TO THE LOW/MID
90S. HEAT INDICES SHOULD HAVE NO PROBLEM REACHING THE MID/UPPER 90S
UNDER PARTLY TO MOSTLY SUNNY SKIES. A FEW POINT LOCALES IN THE
CHAMPLAIN VALLEY MAY TOUCH HEAT INDICES AT OR OVER 100...BUT DON'T
FEEL THAT THE AREAL COVERAGE IS LARGE ENOUGH TO ISSUE A HEAT
ADVISORY. FOR NOW...WILL BE STRONGLY WORDING THAT POTENTIAL IN THE
HWO.
THE COLD FRONT'S SOUTHWARD PROGRESSION TOMORROW NIGHT WILL BE
SLOWED WITH 500 MB HEIGHTS NEARLY PARALLEL TO THE SFC FLOW.
REGARDLESS...WITH THE COLD FRONT IN THE VICINITY IT SHOULD CONTINUE
TO SUPPORT SHOWERS/THUNDERSTORMS INTO THE OVERNIGHT. ANOTHER
WARM/MUGGY NIGHT IN STORE ONCE AGAIN FOR FRIDAY NIGHT WITH SIMILAR
LOWS AS TONIGHT.
THE FRONT WILL CONTINUE TO SLOWLY SAG SOUTHEASTWARD INTO
SATURDAY...FINALLY CLEARING THE AREA LATER SATURDAY NIGHT. HIGH
TEMPERATURES AND DEGREE OF INSTABILITY WILL LIKELY BE KEPT IN CHECK
BY MORE CLOUDY SKIES THAN PREVIOUS DAYS. POPS ON SATURDAY TAPER FROM
LIKELY TO HIGH CHANCE FROM WEST TO EAST SATURDAY TRENDING TO DRY
AFTER MIDNIGHT. STRONG COLD/DRY AIR ADVECTION TAKES PLACE AFTER
FROPA /850 TEMPS FALL FROM 17-18C 12Z SATURDAY TO AROUND 8-10C 12Z
SUNDAY PER SREF PROGS/. DAYTIME HIGHS SATURDAY IN THE LOW/MID 80S
UNDER MOSTLY CLOUDY SKIES...WITH LOWS DROPPING TO THE UPPER 40S TO
THE UPPER 50S IN THE VALLEYS SATURDAY NIGHT WITH THE MARKED CHANGE
IN AIRMASS.
&&
.LONG TERM /SUNDAY THROUGH THURSDAY/...
AS OF 330 PM EDT THURSDAY...LARGE SCALE PATTERN CHANGE WL BRING
MUCH COOLER AND DRIER AIR INTO THE NORTH COUNTRY FOR SUNDAY INTO
MONDAY...BEFORE MORE UNCERTAINTY ASSOCIATED WITH NEXT SYSTEM
DEVELOPS BY TUES/WEDS OF NEXT WK. OVERALLL...GFS/ECMWF AND
ENSEMBLE DATA SHOW DEVELOPING TROF ACRS THE NE CONUS WITH SFC HIGH
PRES OVERHEAD ON SUN/MON...RESULTING IN DRY CONDITIONS WITH NEAR
NORMAL TEMPS. THE COMBINATION OF NW FLW...CAA...AND 85H TEMPS BTWN
6-8C WL RESULT IN HIGHS ONLY IN THE 60S MTNS TO 70S VALLEYS ON
SUN/MONDAY. BY TUES/WEDS...FAST WESTERLY FLW ALOFT DEVELOPS WITH
EMBEDDED VORTS AND AREAS OF ENHANCED MID LVL MOISTURE. SOME
