The episode as NWS BGM wrote it up.
A stationary front across Central New York and a passing weak disturbance supported scattered thunderstorms. One storm became severe with damaging wind gusts. One motorist was injured when a tree fell on their car.
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 3, 1:49 PM EST, 1 hour earlier.
Area Forecast Discussion National Weather Service Binghamton NY 249 PM EDT Mon Jul 3 2023 .SYNOPSIS... Showers and thunderstorms will continue through the evening with isolated strong storms possible. Locally heavy rain may also lead to isolated flash flooding. Scattered showers and storms return on Tuesday and will be followed by hot, dry conditions during the midweek. && .NEAR TERM /THROUGH TUESDAY NIGHT/... 245 PM Update... Scattered showers and thunderstorms have developed as expected this afternoon. Current SPC Mesoanalysis shows that CAPE has increased to around 1000 J/kg and shear of 30 kts is present across the Twin Tiers and areas southward. A Severe Thunderstorm Watch was issued in the counties that fall within SPC's current outlook. This lines up well with the environment as well. Isolated severe thunderstorms are possible with strong, gusty winds as the main threat, but large hail will also be possible. A strong storm or two cannot be ruled out in the few counties north and west of the watch area. On top of the severe threat, there is a concern for localized flash flooding as well. PWATs are near 1.7 inches and warm cloud layer exceeds 10k ft. Heavy rainfall will also be possible, especially in thunderstorms. Based on the last couple of days, those that have observed the most rainfall will be most vulnerable. WPC also extended the Slight Risk for the Excessive Rainfall Outlook to cover the Twin Tiers. Rivers and streams have not responded much over the last two days, so as mentioned above, the main concern will be localized flash flooding. Showers and thunderstorms will continue through at least the late evening hours. The severe threat will decrease after sunset as instability is lost. Still, heavy rainfall will remain possible. Most of the CAMs show just isolated showers after midnight and into the early morning hours Tuesday as a frontal boundary drops south. One more wave will move through on Tuesday, kicking off additional isolated to scattered showers and thunderstorms. Model guidance is showing some instability again, but shear is expected much weaker than today, leading to just short-lived thunderstorms. SPC does clip the NEPA and Catskills with a Marginal Risk. If conditions were to lead to higher instability and better shear up from what is being modeled further south, then isolated strong to severe storms will certainly be possible once again. Temperatures will be mild overnight. Tuesday is looking similar to today with temps in the 70s and 80s during the day and 60s at night. && .SHORT TERM /WEDNESDAY THROUGH THURSDAY/... 245 PM Forecast... Surface high pressure is expected to be over the region during this time period with ensemble forecast guidance also indicating anomalous ridging aloft. We're also seeing +2-3SD 850 mb thermal anomalies with the hottest day expected on Thursday. This should translate into quite warm and humid days with temperatures well into the 80s across the area and low 90s in the valleys and urban areas...particularly Thursday. Shower and thunderstorm chances begin to creep up late in the day Thursday, mainly due to localized destabilization, however, the trends are slowing a bit and we should not really see the effects of an approaching cold front until Thursday night into Friday. && .LONG TERM /THURSDAY NIGHT THROUGH SUNDAY/... 245 PM Forecast... Friday should be unsettled as a cold front pushes through the region, displacing the unstable airmass. Model timing with this feature is reasonable enough to suggest a late morning early afternoon passage...so this will help to limit severe potential, but not necessarily coverage of showers and t-storms. The front runs into the back side of the upper ridge just to our east by Saturday. Overall, precipitation trends should wane over CNY/NEPA aside from some lingering chances over our eastern zones closest to the expected frontal position. For the latter half of the weekend and next Monday...the uncertainty climbs due to model timing differences bringing weak features through the upper flow. The surface pattern becomes rather diffuse, and although this generally suggests a tendency toward precipitation...I don't think either Sunday or Monday will be a washout. Just generally expecting diurnally driven showers and thunderstorms with seasonably warm temperatures and we'll continue with low to mid- range chance PoPs. && .AVIATION /19Z MONDAY THROUGH SATURDAY/... Most sites are VFR currently. With scattered showers/storms popping up across CNY, restrictions may be possible if one passes directly over a terminal. The highest confidence for storms is at ELM, ITH, and BGM. There is lower confidence at SYR, RME, and AVP for storms. If needed, a tempo will be added at these terminals if anything were to develop. Overnight, restrictions are expected at all terminals as fog develops and ceilings drop. AVP will stay above IFR while the rest of the terminals will see IFR and even LIFR restrictions. Throughout this TAF period, winds are expected to be light, though some stronger gusts may be possible if a storm passes over a terminal. Outlook... Tuesday...Isolated afternoon/evening showers and thunderstorms with associated restrictions. Wednesday through Thursday...Mainly VFR. Thursday Night and Sunday...Thunderstorms return Thursday night, lingering into Friday with associated restrictions. Saturday...Mainly VFR; lingering rain showers possible. && .BGM WATCHES/WARNINGS/ADVISORIES... PA...None.
