The episode as NWS BGM wrote it up.
Showers and thunderstorms developed ahead of an approaching cold front in an environment favorable for severe weather with sufficient instability, plenty of moisture and wind shear. This supported the development of some strong to severe storms in the afternoon. Damaging wind gusts knocked down numerous trees and wires and there was one storm which produced large hail.

NWS Binghamton, NY wrote its last area forecast discussion before the first event at Aug 5, 12:53 PM EST, 29 minutes earlier.
Area Forecast Discussion National Weather Service Binghamton NY 153 PM EDT Mon Aug 5 2024 .SYNOPSIS... Warm and humid conditions will persist through today with severe thunderstorms possible this afternoon and evening. Cooler temperatures are expected tomorrow and rain chances will increase through the week with upper level troughing overhead. && .NEAR TERM /THROUGH TUESDAY NIGHT/... 1230 PM Update... Made changes to pops using radar imagery to include showers located over the northern portion of our area. HRRR did the best at capturing these showers, therefore blended this resolution to the forecast. Otherwise made the usual changes to update temperatures and dew points with current observations. 930 PM Update... Satellite imagery shows clouds are moving into the region this morning. This has the potential to limit instability, but it is too early to tell if there will be any impacts. Therefore previous forecast still applies, but this will be monitored for any changes. Minor adjustments were made to update temperatures and dew points with the latest observations. 345 AM Update... Cold front will drop southeast out of Canada today with scattered showers and thunderstorms developing out ahead of it. At this time, several parameters indicate some potential for severe thunderstorms this afternoon and evening. Moist airmass remains in place and a strong push of 0-6km shear of 40KT - 45KT and decent instability of 1000 to 1500 J/kg will help support an environment for potential severe storms. Main threat will be damaging winds and heavy rainfall. Showers and storms will persist into the overnight hours, with the severe threat ending by late evening, however the flash flooding threat will remain through the period. More showers and storms are expected as another perturbation moves through. However, at this time, it appears that the bulk of the thunderstorm activity will occur late in the day and overnight into Wednesday morning. && .SHORT TERM /WEDNESDAY THROUGH THURSDAY NIGHT/... 140 PM Update... Showers from a departing shortwave may linger into Wednesday but look to move out of the region late Wednesday evening. Instability will be quite limited, so anything that remains should be mainly just rain showers, though a thunderstorm or two cannot be ruled out. Weak high pressure will build into the region and will bring a brief period of dry conditions with it. Thursday is trending dry as well, though some showers may be pushed north from Debby, especially into NEPA and the Catskills. An upper-level low/trough deepens over the Great Lakes late Thursday. This will strengthen the southwest flow that will advect tropical moisture into the region and allow showers to spread northward during the overnight hours. PWATs will increase Thursday night to 1.7 to 2 inches, at least based on deterministic guidance, which is right around 2 standard deviations above normal for this time of year. Ensemble guidance is not as high with PWATs and keeps higher values along the coastline. Looking at soundings, there will also be warm cloud depths exceeding 12k ft. With plenty of moisture to work with, heavy rain showers will be possible. Given the rainfall expected earlier in the week, conditions may become more favorable for localized hydro concerns, but that will be something we will need to monitor throughout the week. Temperatures will climb into the 70s and low 80s both Wednesday and Thursday. Wednesday night will be the cooler of the two as temps fall into the 50s and 60s. Thursday night will be at least a few degrees warmer with more locations staying in the 60s. && .LONG TERM /FRIDAY THROUGH SUNDAY/... 140 PM Update... While the end of the week is somewhat uncertain based on how the remnants of Debby track and the upper trough interact, the potential for heavy rain will remain present through Friday with conditions potentially improving over the weekend. There will also be enough instability to support thunderstorms. Model guidance does differ on whether or not Debby stays as an organized surface low or if the upper feature becomes more dominant. Either way, high PWATs are still modeled through the end of the week, though the greatest moisture content will be along the coast. WPC does have a slight risk for excessive rainfall for a portion of our area. Similarly to the short term, we will have to monitor rainfall and conditions throughout the week to have a better idea of hydro concerns. River ensemble guidance are mixed, but there are non-zero chances that some of our more trouble points could exceed action or even flood stage by week's end. Showers linger into Saturday but do begin to move out. Drier conditions become more probably Saturday night into Sunday, though that will depend on the location of the upper-level low as some weaker waves may kick off passing showers. Given the uncertainty in the forecast, slight chance to low chance PoPs are in the forecast through the start of next week. With ongoing showers and falling heights throughout the weekend, temperatures will only max out in the 70s to low 80s this period. Overnight lows will be in the 50s and 60s. && .AVIATION /18Z MONDAY THROUGH SATURDAY/... VFR conditions are expected for the beginning of the period. A cold front will enter the region this afternoon kicking off scattered thunderstorms. These storms will bring restrictions at all sites. Mainly expecting MVFR to Fuel Alt ceilings with brief periods of IFR visibility possible with some showers. Model guidance tonight hints at ceilings as low as Below Alt mins at ELM and possibly ITH. Confidence was not as high to include at ITH. MVFR ceilings will be possible through the early morning hours on Tuesday before lifting to VFR for the remaining period. .Outlook... Tuesday...Mostly VFR, but scattered showers and thunderstorms expected in the afternoon and evening, bringing associated restrictions. Storms will be most likely at AVP. Wednesday through Thursday...Mainly VFR. Friday...Chances for showers and thunderstorms increase again, with associated restrictions. && .BGM WATCHES/WARNINGS/ADVISORIES... PA...None.
