The episode as NWS BGM wrote it up.
A strong shortwave aloft lifted north across the region Wednesday afternoon and evening and interacted with a weak cold front that was dropping southward out of southern Canada. A line of organized thunderstorms developed along the front and became severe as it passed through the Finger Lakes region. These thunderstorms produced severe winds and small hail as they propagated eastward.

NWS Binghamton, NY wrote its last area forecast discussion before the first event at Jun 10, 9:17 PM EST, 13 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE BINGHAMTON NY 1017 PM EDT WED JUN 10 2015 .SYNOPSIS... A COLD FRONT WILL DROP THROUGH THE AREA TONIGHT WITH THUNDERSTORMS ACROSS THE NORTH...AND A FEW SHOWERS FOR SOUTHERN NEW YORK AND NORTHERN PENNSYLVANIA. HIGH PRESSURE WITH DRY AIR WILL RETURN FOR WEDNESDAY BRINGING WARM AIR AND SUNNY SKIES. LOW PRESSURE APPROACHING FROM THE OHIO VALLEY WILL BRING RAIN BACK TO THE AREA FRIDAY NIGHT AND EARLY SATURDAY. && .NEAR TERM /UNTIL 6 AM THURSDAY MORNING/... 1015 PM UPDATE...AS EARLIER THOUGHT...THUNDERSTORMS FIRED AHEAD OF THE COLD FRONT IN THE LAST COUPLE HOURS WITHIN A STRONGLY FORCED...SHEARED...BUT ONLY WEAKLY UNSTABLE ENVIRONMENT. SCATTERED STORMS HAVE GONE SEVERE ACROSS OUR NORTH COUNTRY WITH A WIND THREAT AS MAIN CONCERN. SVR WATCH IN EFFECT UNTIL 1 AM...AND ALL LOOKS GOOD WITH TIMING AND IMPACT AREAS. MESO MODELS SUGGEST RAPID WANING AFTER 06Z AS FORCING LIFTS NORTHEAST AND STORMS DROP SOUTH. GENERAL POP/WX IDEA STILL ON TARGET. NO OTHER CHANGES. PREVIOUS DISCUSSION... GROWING CONCERN THIS EVENING THAT A STRONG...DYNAMICALLY FORCED FRONTAL SYSTEM MOVING INTO A DESTABILIZING ENVIRONMENT ACROSS WEST CENTRAL AND NORTHERN NEW YORK WILL LEAD TO NEW DEVELOPMENT OF THUNDERSTORMS DURING THE LATE EVENING AND OVERNIGHT PERIOD IN OUR AREA. MODEST LOW LEVEL WARM AND MOIST ADVECTION...AS SEEN IN THETA-E FIELDS...WAS STEEPENING LOW-MID LVL LAPSE RATES OVER THE REGION. 500-300 MB JET STREAK ADVANCING ON THE AREA FROM LOWER ONTARIO WAS PROVIDING OVER 50 KTS OF 0-6 KM BULK SHEAR...AND EVEN TURNING IN THE LOW LEVELS IS PRESENT WHICH COULD SUPPORT STRONG UPDRAFTS AND A SMALL CHANCE FOR HEALTHY MESOCYCLONES. MESOSCALE MODELS SUGGEST NEW CONVECTIVE DEVELOPMENT DURING THE 02Z-06Z TIME FRAME JUST AHEAD OF THE ADVANCING COLD FRONT ACROSS WRN NEW YORK...AND THIS LOOKS REASONABLE. REALLY LIKE THE NAM4KM AND CANADIAN RGEM IDEAS...ALTHOUGH HRRR AND WRF-NMM ALSO SEEM TO HAVE SIMILAR SOLUTIONS. THE MAIN SHORT WAVE FORCING LOOKS TO AFFECT MAINLY OUR NORTHERN THIRD OF THE FORECAST AREA...WHICH IS WHERE WE ARE EXPECTING ANY OF THE STRONGER STORMS TO BE...SAY ROUGHLY FROM PEO-SYR-UCA...WITH MORE GENERAL TSTM ACTIVITY FURTHER SOUTH...IF IT CAN MAKE IT. BULK OF FORECAST MODEL GUIDANCE SUGGESTS A 02Z-07Z WINDOW OF BEST CHANCE FOR THUNDERSTORM ACTIVITY...INCLUDING ANY SVR POTENTIAL. FORECAST CHANGES FROM THIS AFTERNOON FEATURE INCREASED POPS ACROSS THE NORTHERN ZONES TO LIKELY-CATEGORICAL AT TIMES...WITH A RAPID DROP OFF TO NEAR ZERO CHANCES FOR RAIN IN NORTHEAST PA THROUGH THE NIGHT. HIGHER POP AREAS WERE ALSO GIVEN ENHANCED HAIL...GUSTY WINDS...HEAVY RAIN...FQT LIGHTNING TERMINOLOGY. NO OTHER SIGNIFICANT CHANGES WERE MADE. && .SHORT TERM /6 AM THURSDAY MORNING THROUGH SATURDAY/... REMAINS OF THE FNT COULD TRIGGER SOME CONV OVER THE NEPA ZONES DURING THU...ESP CNSRDG THE HTG XPCTD. FCST SNDGS...ESP THE NAM...SHOW AVBL ENERGY FOR CONV TMRW AFTN. LIMITING FACTOR WILL BE THE VERY DRY AIR...AND A MORE STABLE MID LYR SHOWN ON THE MODELS. INTRSTG TEMP FCST FOR NEPA WITH THE MET GUID GIVING AVP 90F. WITH THE BLENDED GUID STILL GOT AN 88F FOR AVP SO IT WILL BE A WRM DAY. WEAK RDGG SFC AND ALFOT FOR FRI AS A WV AND SFC LOW DEEPEN TO THE WEST. SOME ISLTD CONV PSBL IN THE DIRTY RDG AND MORE CLDS SHD LIMIT THE HTG BY A FEW DEGREES OVER NEPA. BEST JET DYNAMCS PASS NORTH OF NY FRI NGT AND SAT AND SHD BE THE FOCUS OF HEAVY RAIN...LVG THE FCST AREA IN SCT TO MUMEROUS SHWRS FROM LATE FRI INTO EARLY SAT. HIPRES BLDS IN DURING SAT BRINGING CLRG SKIES LTR IN THE DAY. && .LONG TERM /SATURDAY NIGHT THROUGH WEDNESDAY/... 1 PM UPDATE... UNSETTLED WEATHER WITH MULTIPLE FRONTS IN THE VICINITY FOR THE DURATION. SHOWERS WILL BE COMMON AND POSSIBLY THUNDERSTORMS. TEMPERATURES AT OR ABOVE NORMAL. SAT NGT TO SUN NGT FAIRLY DRY WITH HIGH PRESSURE OVER NEW ENGLAND. A WARM FRONT WILL SLOWLY PUSH NE TOWARDS THE AREA FOR MONDAY. A SLOW MOVING COLD FRONT WILL BE NORTHEAST OF THE AREA TUESDAY THEN PUSH THROUGH WED. FOLLOWED WPC GUIDANCE. NOTHING OF SIGNIFICANCE FOR WEATHER THIS FAR OUT. && .AVIATION /02Z THURSDAY THROUGH MONDAY/... CONCERN FOR THIS PERIOD WILL BE THUNDERSTORMS TRACKING SE FROM WESTERN NY AND SOUTHERN ONTARIO AHEAD OF A COLD FRONT. CURRENTLY, JUST A FEW STRONG STORMS ON RADAR BUT INDICATIONS THESE MAY INCREASE IN COVERAGE..ESPECIALLY FOR THE NORTHERN SITES SO WE HAVE INCLUDED THE MENTION OF STORMS IN THE TAFS FOR KITH/KSYR/KRME FOR LATER THIS EVENING AFTER 2Z. IF STORMS DO MATERIALIZE FOR THESE AREAS, AT LEAST MVFR RESTRICTIONS ARE LIKELY IF NOT IFR. FOR KELM/KBGM, LESS CERTAINTY IF STORMS WILL OCCUR HOWEVER RESTRICTIONS IN VISBY ARE LIKELY OVERNIGHT FOR KELM WITH MVFR VIS. SHOWERS/STORMS ACTIVITY SHOULD MISS KAVP TO THE NORTH WITH VFR CONTINUING. IN ADDITION TO FLIGHT RESTRICTIONS STORMS ALSO HAVE THE POTENTIAL TO PRODUCE STRONG AND GUSTY WINDS. SHOWERS/STORMS EXIT BY LATER TONIGHT WITH VFR FOR THURSDAY UNDER A MIX OF SUN AND CLOUDS. ONE EXCEPTION COULD BE KAVP WHERE A FEW STORMS WILL BE POSSIBLE THURSDAY AFTERNOON BUT MOST LIKELY THESE STAY SOUTH. WINDS WILL GENERALLY BE S/SW TONIGHT AROUND 10 KNOTS EXCEPT LOCALLY HIGHER IN THUNDERSTORMS. FOR THURSDAY WINDS WILL BE W/NW AROUND 10 KNOTS GUSTING 15 TO 20 KNOTS BEHIND THE FRONT. .OUTLOOK...
