A weak frontal boundary and a strong upper level disturbance helped develop numerous severe and torrential rain producing thunderstorms. Thunderstorms which repeatedly moved over the same locations along the Southern Tier of New York produced rainfall estimates of 3 to 4 inches in a short amount of time.

The episode as NWS BGM wrote it up.
A weak frontal boundary and a strong upper level disturbance helped develop numerous severe and torrential rain producing thunderstorms. Thunderstorms which repeatedly moved over the same locations along the Southern Tier of New York produced rainfall estimates of 3 to 4 inches in a short amount of time. This resulted in widespread areas of minor urban flooding and isolated flash flooding.
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 Binghamton, NY wrote its last area forecast discussion before the first event at Jul 13, 6:52 PM EST, 1 hour 18 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE BINGHAMTON NY 752 PM EDT SUN JUL 13 2014 .SYNOPSIS... AN UPPER LEVEL LOW DIGGING INTO THE GREAT LAKES WILL BRING PERIODS OF SHOWERS AND THUNDERSTORMS OVER THE NEXT FEW DAYS. THE ASSOCIATED FRONTAL SYSTEM WILL MOVE OFFSHORE BY TUESDAY NIGHT, WITH DRIER WEATHER AND COOLER TEMPERATURES FOR MID WEEK. && .NEAR TERM /UNTIL 6 AM MONDAY MORNING/... WELL DEFINED UPPER LEVEL WAVE SEEN WELL ON THE WATER VAPOR IMAGERY OVER EASTERN ONTARIO CONTINUES TO PRESS EAST AS AN UNSEASONABLE UPPER LEVEL LOW DROPS SEWRD TWD THE GREAT LAKES. THE HGHT FALLS WITH THIS DEEPENING UPPR WAVE AND ENTIRE ANOMALOUS UPPER LEVEL LOW PATTERN WAS SUPPORTG A STRG MID TO UPPER LEVEL JET THAT WAS PUSHING EWRD INTO THE ST LAWRENCE VALLEY. THIS HAS INCREASED THE BULK WIND SHEAR BETWEEN 0 AND 6 KM ABV 30 KNOTS. THIS UPPER LEVEL FEATURE WAS ASSCTD WITH A STRG BELT OF SWRLY FLOW AT AROUND 1 KM TOPPING 30 KNOTS...AGAIN INCREASING LL WIND SHEAR TO BTWN 25 AND 30 KNOTS. MEANWHILE...THE LL/S WERE STILL MOIST WITH DWPTS IN THE LOWER 70S AND WITH INSOLATION EAELIER TODAY...CAPES ROSE TO BETWEEN 1500 AND 2000 J/KG OR SO. THIS HAS SET THE STAGE FOR A COMPLEX OF STRG TO SVR TSTMS THAT WAS PRESENTLY ACROSS ERN NY TO SC NY AND CNTRL PA. WITH SUCH STRG LL WIND SHEAR WE HAVE SEEN SOME HP-LIKE SUPERCELLUAR STRUCTURES EMBEDDED IN THIS LINE AND WE HAVE RECEIVED PHOTOS OF FUNNELS AND A REPORT OF SIGNIFICANT DAMAGE IN SCHULYER COUNTY. MORE DAMAGE LIKELY WILL COME IN. SVR WATCH CONTINUES. WILL CONTINUE CLEAR COUNTIES ON THE NW EDGE AS THE STORMS PASS TO THE SE. BELIEVE STORMS WILL BE S AND E OF NE PA BY LATE EVENING. AFTER THE STORMS PASS...THE LL/S REMAIN VERY MOIST AS THE SFC BNDRY IS NOT PROJECTED TO PUSH THAT FAR SOUTHWARD. IT SHUD REACH NRN NY STATE BTWN 9 AND 12Z. THINK SOME PATCHY DENSE FOG WILL DEVELOP OVERNIGHT AS SKIES CLEAR. WILL BE ADDING TO GRIDS SOON. && .SHORT TERM /6 AM MONDAY MORNING THROUGH WEDNESDAY/... MONDAY...BOUNDARY WHICH IS CURRENTLY MOVING THROUGH AREA WILL REMAIN OVER EASTERN PA AND BE THE FOCUS FOR MORE SIGNIFICANT CONVECTION BY MONDAY AFTERNOON. WILL CONTINUE WITH CHC POPS FOR MUCH OF CENTRAL NY BUT LIKELY FOR NE PA, SRN CATSKILLS AND LOCAL BGM AREA. BASED ON SVR WX INDICES A FEW STORMS COULD APPROACH SVR LIMITS ALTHOUGH THE MAIN THREAT MAY BE HEAVY RAIN AS CONVECTION PERSIST OVER NE PA AND AIRMASS REMAIN VERY MOIST WITH PWATS AROUND 2 INCHES. MONDAY NIGHT...ACTIVITY WILL DIMINISH BY LATE EVENING AS APPROACHING UPPER LEVEL WAVE MOVES INITIAL BOUNDARY THROUGH AND MAIN SFC COLD FRONT APPROACHES REGION. WILL CONTINUE WITH CHC POPS THROUGH THE OVERNIGHT PERIOD. TUESDAY...DEEP H5 TROF MOVES INTO NEARBY SOUTHERN ONTARIO AS SFC COLD FRONT MOVES THROUGH FA FROM I81 WEST DURING THE MORNING HOURS AND POINTS EAST DURING THE AFTERNOON. INSTABILITY LOOKS FAIRLY WEAK EXCEPT FOR THE FAR SE FA WHERE MODELS SUGGEST SEVERAL HUNDRED J/KG. WILL CONTINUE WITH HIGH CHC POPS THROUGH PERIOD. TUESDAY NIGHT/WEDNESDAY...UPPER LEVEL TROF SETTLES OVER THE NORTHEAST AS SFC HIGH PRES GRADUALLY BUILDS SOUTH FROM THE UPPER GREAT LAKES. AFTER SOME LINGERING SHOWERS FOR THE ERN CWA TUE EVENING PERIOD WILL BE MAINLY DRY AND PARTLY CLOUDY. HIGHS ON WED WILL GENERALLY RANGE IN THE LOWER TO MIDDLE 70S. && .LONG TERM /WEDNESDAY NIGHT THROUGH SUNDAY/... NOON UPDATE... THE BIG STORY DURING THE LONG TERM FORECAST WILL BE A BROAD UPPER LEVEL TROF OVER THE EASTERN HALF OF THE US WITH COOLER THAN AVERAGE TEMPS, AND A POSSIBLE RETURN TO UNSETTLED WEATHER BY THE WEEKEND. MAINLY DRY WEATHER IS EXPECTED WEDNESDAY NIGHT INTO EARLY FRIDAY. DURING THIS PERIOD A SHORT WAVE WILL MOVE THROUGH IN THE MEAN FLOW DURING THE DAY THURSDAY. I CONTINUED A DRY FORECAST BUT A POP UP SHOWER CAN'T BE RULED OUT THIS DAY AS THE SHORT WAVE MOVES THROUGH. WITH THE BASE OF THE UPPER LEVEL TROF STILL OVER CENTRAL TX, WE AREN'T QUITE OUT OF THE WOODS FOR MORE PRECIPITATION AS WE HEAD TOWARD THE WEEKEND. AS THIS TROF MOVES EAST OVER THE SOUTHEASTERN US, A DEEP SOUTHWEST FLOW WILL DEVELOP AND TRANSPORT MOISTURE UP THE ATLANTIC COAST. THE TIMING AND HOW FAR NORTH THE MOISTURE GETS IS STILL VERY MUCH IN QUESTION. THE OLDER RUNS OF THE GFS ARE ABOUT 24 HOURS FASTER THAN THE EURO, BRINGING IN SHOWERS BY FRIDAY EVENING WITH THE EURO NOT UNTIL SATURDAY EVENING. WHATEVER THE CASE IT DOES APPEAR CHANCES WILL INCREASE FOR SHOWERS OVER THE WEEKEND ITSELF. ON THE FRONT END I PUT IN JUST A 20% CHANCE FOR SHOWERS IN NEPA FRIDAY BUT SAVE HIGHER CHANCES FOR SAT/SUN. IF THE PATTERN HOLDS CHANCES FOR RAIN MAY NEED TO BE INCREASED THIS WEEKEND BUT STILL WAY TOO FAR AND UNCERTAIN AT THIS POINT FOR ANYTHING MORE THAN THAT. && .AVIATION /00Z MONDAY THROUGH FRIDAY/... HAVE TEMPO TSRA 00-02Z ONLY AT KAVP AS STORMS WILL HAVE EXITED REST OF KBGM TAF SITES BY 00Z. THEN SKIES WILL BECOME MOSTLY CLEAR. WITH LATEST ROUND OF RAINFALL AND HIGH DEWPOINTS I HAVE IFR TO VLIFR ALL TAF SITES EXCEPT KSYR AND KAVP WHERE I HAVE MVFR. CONFIDENCE IS LOW TO MEDIUM KRME AND KITH FOR IFR...AND HIGH KELM AND KBGM. TIMING...8-12Z KBGM... KITH AND KRME. HAVE KELM IFR 6-14Z AND VLIFR 9-13Z. AFTER FOG LIFTS BY 13-14Z...I SEE VFR CUMULUS LAYER AND ANOTHER ROUND OF TSRA FORMING IN THE AFTERNOON ESPECIALLY THE SERN PTN OF OUR FORECAST AREA. SO I HAVE PROB30 GROUPS FOR 20-24Z KBGM AND KAVP FOR MVFR TSRA. REST NO MENTION YET OF THUNDER. WINDS WILL BE MAINLY LIGHT WRLY THRU THE PD. OUTLOOK... MON NGT THROUGH TUE NGT...POTENTIAL RESTRICTIONS FROM SHRA/TSRA. WED/THUR/FRI...PRIMARILY VFR. && .BGM WATCHES/WARNINGS/ADVISORIES... PA...NONE.
