The episode as NWS ILN wrote it up.
An upper level disturbance produced widespread showers and thunderstorms across central Ohio during the overnight hours.
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 Wilmington, OH wrote its last area forecast discussion before the first event at Jul 5, 8:50 PM EST, 2 hours 13 minutes earlier.
AREA FORECAST DISCUSSION National Weather Service Wilmington OH 950 PM EDT Tue Jul 5 2022 .SYNOPSIS... Hot and humid conditions will persist through the remainder of the week, along with multiple rounds of showers and thunderstorms. && .NEAR TERM /UNTIL 6 AM WEDNESDAY MORNING/... With convection firing up across northern IN/OH in a very unstable airmass, precipitation holding together in the unstable environment under NW flow. While expectation for some strong to possibly severe storms with this activity, areas east of the stalled boundary currently extending N-S in eastern Indiana do not possess nearly as favorable of low level lapse rates. However, a much better DCAPE set up than earlier today, at least for the next couple of hours. An even more favorable potentially severe scenario will be with the developing system as associated with the shortwave currently over northern IL, expected to push another round through the area after about 08z. So multiple rounds expected overnight, with an additional concern in this ridge-rider NW flow set up being the potential for training storms and heavy rainfall/flood issues. Holding off for now on any flash flood watch, but will have to monitor and consider the potential for a quickly issued flash flood watch. Muggy overnight lows near 70 to lower 70s. && .SHORT TERM /6 AM WEDNESDAY MORNING THROUGH WEDNESDAY NIGHT/... Regardless of convective trends Tuesday night through Wednesday morning, the short term period is still expected to be conducive for additional thunderstorm activity due to the moist environment and lack of frontal passage. In fact, confidence is increasing in another shortwave moving through during the late afternoon and evening hours, leading to higher chances for thunderstorm activity. While thunderstorm activity can be expected, the level of severity will be dependent on how much heating can occur during the afternoon ahead of the best energy. Given the uncertainty with Tuesday's events, it is hard to have high confidence for severe weather, so Marginal/Slight categories from SPC are appropriate. While thunderstorms are expected to occur throughout the day, if some locations remain dry through early afternoon, heat indices may become concerning. This will remain mentioned in the HWO instead of a Heat Advisory due to the uncertainty with thunderstorm evolution. && .LONG TERM /THURSDAY THROUGH TUESDAY/... An expansive midlevel ridge will be centered over the lower MS Rvr Vly for the end of the workweek, with the OH Vly remaining positioned on the N/NE periphery of that broader pooling of better LL moisture/heat centered just to the SW. This will keep the ILN FA, and in fact much of the region, near the overlap of an oscillating LL thermal/instby gradient and the better deeper-layer shear associated with stronger midlevel flow on the edge of the high pressure system. And within this broad WNW to ESE midlevel flow will be weak/transitory S/Ws, which will progress rather quickly to the ESE at various points Thursday into Friday, providing just enough forcing and ascent to initiate several complexes of storms as it does so, with a constant modulation of the LL thermal/moisture gradient. Trying to time out these specific rounds of storms for any one location would prove to be imprudent as this pattern remains highly in-flux. Therefore, the extended fcst was constructed strictly from a pattern recognition perspective, rather than one focused on specifics regarding timing and trying to determine where and when storms will be draped across the region. The pattern itself suggests the active stretch from the near/short term periods will continue into the beginning of the long term period and will be characterized by a very humid airmass and episodic storm chances throughout the OH Vly. There will likely be episodes of severe storms embedded within this larger-scale active pattern, as well as locally heavy rainfall and flooding potential given PWATs will be running 150-175% seasonal norms, as already depicted by the 1.97" PWAT sampled on the KILN 05.12Z RAOB. The high to extreme instby, if overlapped sufficiently both spatially and temporally with the better LL and deeper-layer shear, may provide periods of strong winds with any of the more organized storm complexes that are able to develop and move through the local area. Highs will generally be in the upper 80s and lower 90s both Thursday and Friday, although confidence remains lows given uncertainties in cloud cover/storm coverage on both days. Overnight lows will be in the lower 70s Thursday night, but expect to see some slightly cooler/drier air filter in from the N late Friday night into the beginning of the upcoming weekend. There are some indications that a subtle pattern shift will evolve for this weekend as a potent S/W moves through the OH Vly Friday evening into Friday night, with troughing developing further SW into the OH Vly by early Saturday through this upcoming weekend. While some timing differences remain, guidance is in good agreement showing this transition to a drier airmass for Saturday and Sunday, potentially lingering into Monday as well, as sfc high pressure with Canadian origins drifts south into the interior NE CONUS. This will allow for a refreshingly-dry airmass to filter into the region through the day on Saturday and continuing into Monday before airmass modulation begins once again ahead of the next system toward the end of the long term period. The pattern this weekend suggests dry conditions with lowering humidity, with highs in the low/mid 80s, with overnight lows in the upper 50s and lower 60s. && .AVIATION /02Z WEDNESDAY THROUGH SUNDAY/... With the region currently dominated by cold pool, convective activity over the next couple of hours will be minimal at especially KILN/KCVG/KLUK. With increasing activity across northern Ohio/Indiana ahead of a surface boundary, this activity will push south and affect KCMH/KLCK after about 04z, and KDAY after about 07z. A messy and uncertain pattern, with generally VFR conditions, but MVFR possible in thunderstorms which would contain heavy rain. Varying solutions for how these storms will play out, however, general thoughts are active showers with scattered storms in the 08-15z timeframe, followed by a general lull, and then renewed activity after 18z. Some concern for MVFR ceilings after 00z in central Ohio beyond the current TAF period for those locations, but again, confidence is low. OUTLOOK...Thunderstorms are possible Wednesday night into Saturday. && .ILN WATCHES/WARNINGS/ADVISORIES... OH...None. KY...None.
