The episode as NWS PBZ wrote it up.
Rainfall during the previous day, plus during the morning of July 2nd, kept the ground saturated. An early afternoon break in rainfall was followed by additional thunderstorm development in western and central Ohio by late afternoon. These storms took advantage of an environment containing 1500 J/kg of surface-based CAPE, along with marginal sufficient deep shear of 30 knots to create severe thunderstorms with a number of wind damage reports. Isolated flash flooding was also reported in Tuscarawas County with repeated rounds of heavy rain.

NWS Pittsburgh, PA wrote its last area forecast discussion before the first event at Jul 2, 5:02 PM EST, 21 minutes earlier.
Area Forecast Discussion National Weather Service Pittsburgh PA 602 PM EDT Sun Jul 2 2023 .SYNOPSIS... Passage of a trough to our west under a warm, moist air mass will continue to stir showers and thunderstorms through tonight. The main threat in the next 12 hours will be flash flooding with training storms. The severe threat, mainly for damaging winds, will remain south of I-70 through midnight. && .NEAR TERM /UNTIL 6 AM MONDAY MORNING/... The center of a weakening upper-lvl is currently situated near Chicago as of 6pm. For areas southeast of the pivoting low, convection has redeveloped over the last few hours within and along a dry slot in Indiana/central Ohio. With MUCAPE ranging between 1200J/kg to 1600J/kg this evening and effective shear near 30kts, eastern Ohio and areas south of I-70 will likely be the area of concern for damaging winds and small hail. PWATS are higher than yesterday, nearing 2.00 inches, based on GOES-16 temp/moisture profiles in eastern OH. Therefore, the potential for flash flooding continues today for slow moving storms along weak boundaries and areas that experienced "training" storms. Expect rainfall rates to exceed 1-2 inches per hour in some of these passing storms with abundant surface moisture and a deep warm cloud layer. Based off the latest GFS run, the depth of the freezing level to lift condensation level will exceed 13kft, which will produce efficient rainfall rates. The potential for flooding will continue after midnight but the severe threat will likely diminish with boundary-layer decoupling noted in some soundings. Dense fog is not likely, however there are elevated probabilities of reduced visibility near I-80 between 3am to 6am. && .SHORT TERM /6 AM MONDAY MORNING THROUGH TUESDAY NIGHT/... Showers and isolated thunderstorms will continue for the area on Monday with a crossing cold front, then gradually waning in coverage as the weak surface low and associated cold front track eastward. Coverage is likely to be highest during the afternoon hours with peak heating. Lingering showers will exit the area Monday night. Northwesterly flow behind the front will help cool temperatures a few degrees from previous days. Brief ridging on Tuesday will significantly lower shower/thunderstorm potential for Independence Day and into Wednesday. While we can't rule out a isolated shower/thunderstorm in the afternoon, kept PoPs generally around 25% or less during the afternoon for both days. Highs will warm into the mid 80s for most with dewpoints in the upper 60s. && .LONG TERM /WEDNESDAY THROUGH SUNDAY/... A much stronger trough will begin to move into the region by Thursday and Friday. Once again the ridge in the southeast just off the SE coast will hinder the approach of the front keeping renewed convection for Thursday and Friday afternoons as a stalled surface boundary seems likely. This will likely return to a diurnally driven environment by the that time period. By the weekend, the front shifts to the east shifting the bulk of the rainfall to the east as the main boundary pushes east. Behind this will be a low confidence forecast as ridging tries to take over, the lingering air mass will make for an unstable environment in the afternoons. So did leave low chance pops inherited by the NBM. && .AVIATION /21Z SUNDAY THROUGH FRIDAY/... General improvements are expected today with many ports clearing to VFR, with MVFR maintenance still in the cards for FKL and DUJ. Thunder mentions continue to be omitted this afternoon given morning clouds and surface stabilization. Storm chances could not be ruled out for FKL and DUJ late afternoon with a slight amount of instability over saturated low levels. During the nighttime hours, gusts should subside slightly with decoupling. Winds will back slightly to the south ahead of the next surface trough. As this pushes through, thunderstorms will progress into the region, with temporary restrictions possible. Storm changes will be most likely for ZZV, and decrease from west to east as they progress. DUJ/FKL are less likely to see storms with minimal daytime heating, so VCTS was noted for now. Recent rainfall and continued low level saturation will bring MVFR/IFR restrictions once again tonight, though precipitation seems unlikely by sunrise for most areas. Restrictions will lift beyond daybreak, though afternoon thunderstorms will be possible once again tomorrow. There is still low confidence in tomorrow's coverage. .OUTLOOK... After storms Monday and lingering restriction potential through Monday night, VFR is likely to return into the holiday. Restrictions may return briefly Tuesday night, but VFR is likely to prevail through late week otherwise. && .PBZ WATCHES/WARNINGS/ADVISORIES... PA...None. OH...None.
