The episode as NWS BGM wrote it up.
A wave that was embedded within southwesterly flow aloft moved over the region Sunday afternoon, the 19th. This wave initiated showers and thunderstorms in a very unstable atmosphere. Some of these storms became severe and produced damaging winds and large hail.

NWS Binghamton, NY wrote its last area forecast discussion before the first event at Jul 19, 2:44 PM EST, 56 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE BINGHAMTON NY 344 PM EDT SUN JUL 19 2015 .SYNOPSIS... WARM AND HUMID AIR WITH SCATTERED THUNDERSTORMS TONIGHT WILL BE REPLACED BY A COLD FRONT WITH DRIER AND SOMEWHAT COOLER AIR ON MONDAY. ANOTHER COLD FRONT WITH A REINFORCING SHOT OF COOLER AIR WILL BRING MORE SHOWERS FOR TUESDAY. && .NEAR TERM /THROUGH TONIGHT/... AFTN TEMPS HAVE REACHED THE MID TO UPPER 80S ACROSS THE REGION WITH DEWPTS AROUND 70 PRODUCING SFC BASED CAPES OF 3000+ J/KG...THE PROBLEM IS THAT WE ARE SOMEWHAT CAPPED...THOUGH THAT IS BREAKING DOWN SLOWING RIGHT NOW...WE HAVE REALLY POOR MID LVL LAPSE RATES AROUND 5.5 TO 6...AND REALLY NO TRIGGER/FORCING MECHANISM AS OF THIS WRITING AND ARE CURRENTLY SITTING IN THE LESS THAN FAVORABLE RIGHT EXIT REGION OF THE UPPER LEVEL JET. SO WHAT DOES ALL THAT MEAN...ITS LIMITING THE SHOWERS AND THUNDERSTORMS FROM DEVELOPING AND GETTING GOING...FOR NOW AND UNTIL SOME OF THESE FACTS CHANGE IT MAY TAKE SOME TIME FOR MORE EXTENSIVE COVERAGE AND STRONGER SHOWERS AND THUNDERSTORMS TO BE MOVING ACROSS THE REGION. UPPER LEVEL SHORTWAVE AND SFC FRONT WILL FINALLY ENTER THE REGION LATER TONIGHT AND WITH THAT THE RIGHT ENTRANCE REGION OF THE UPPER LEVEL JET ALONG WITH A MORE DIFFLUENT FLOW ALOFT ALL ALLOWING FOR BETTER COVERAGE AND STRENGTH TO THE CONVECTION...THOUGH WE WILL BE LOSING HEATING AS POSSIBLE LIMITING FACTOR. WOULD NOT BE SURPRISED FOR A FEW STRONG STORMS WITH THE CURRENT SET UP...ALSO WITH PWATS NEARING 2.0 INCHES HEAVY RAINFALL WITHIN STORMS WILL BE POSSIBLE. LOWS WILL REMAIN ABOVE SEASONAL AVGS. && .SHORT TERM /MONDAY THROUGH MONDAY NIGHT/... SFC RIDGING WILL MOVE IN BEHIND THE SYSTEM AND DRY OUT THE REGION...DEWPTS WILL DROP BY 5-10 DEGREES ACROSS THE REGION LINGERING IN THE LOWER 60S...WILL DEFINITELY BE NOTICABLE. PLENTY OF SUNSHINE MONDAY WITH HIGHS PUSHING INTO THE LOWER AND MIDDLE 80S FOR MOST. OVER LOWS WILL DROP INTO THE MID TO LOWER 60S WITH SOME HIGHER CLOUDS POSSIBLE MOVING IN LATE OVERNIGHT AS THE NEXT SYSTEM APPROACHES. STRONG MODEL AGREEMENT ALLOWS FOR HIGH FORECAST CONFIDENCE FOR MONDAY. && .LONG TERM /TUESDAY THROUGH SUNDAY/... 330 PM UPDATE... A GENERAL TROF IS EXPECTED TO BE IN PLACE ACROSS THE NORTHEASTERN STATES THROUGH THIS PERIOD. A COLD FRONT BRINGS THE BEST CHANCE OF SHOWERS FOR THE EXTENDED PERIOD THROUGH ON TUESDAY. STILL BROAD BRUSHING THIS EVENT DUE TO TIMING ISSUES. REST OF THE WEEK WILL FEATURE COOLER THAN NORMAL TEMPERATURES WITHIN THE ANOMALOUSLY LOW HEIGHTS AND THICKNESSES...BUT GENERALLY FAIR WEATHER AS SFC HIGH PRESSURE BUILDS IN FROM WEDS-SAT. MODELS SHOW BETTER INDICATIONS OF WEAK WAVES APPROACHING SUNDAY...AND HAVE INCREASED RAIN CHANCES AGAIN FOR THAT TIME PERIOD. && .AVIATION /18Z SUNDAY THROUGH FRIDAY/... THUNDERSTORMS HAVE FIRED ACROSS CNY AND HAVE AFFECTED SOME OF THE AIRPORTS WITH BRIEF RESTRICTIONS ASSOCIATED WITH HEAVY RAIN AND CIGS. THE CONCERN WILL BE FOR THE NEXT COUPLE HOURS (23Z) BEFORE A POSSIBLE BREAK IN ACTIVITY. A STRONGER WEATHER FEATURE WILL ARRIVE DURING THE LATER EVENING WITH ANOTHER POTENTIAL ROUND OF THUNDERSTORM ACTIVITY ACROSS CNY. THIS IS A LOW CONFIDENCE EVENT...SO WILL HOLD OFF ON ADDING TO FORECAST FOR NOW AND AMEND DPENDING ON TRENDS. LOSS OF DAYTIME HEATING MAY HELP TO DIMINISH THREAT BY MIDNIGHT OR LATER. .OUTLOOK...
