The episode as NWS PBZ wrote it up.
A warm front crossed the Upper Ohio Valley on the morning of the 24th, putting the region squarely in a warm sector behind the boundary. Abundant moisture and steeping low-level lapse rates were noted on the Pittsburgh morning sounding. Storms were able to form in eastern Ohio ahead of a trough preceding a cold front by late afternoon. The line of thunderstorms pushed across portions of northern West Virginia and into southwest Pennsylvania into early evening, before mostly weakening as the storms passed northeast of Pittsburgh. Abnormally high freezing levels helped to prevent much hail, but copious amounts of instability and shear allowed for numerous reports of wind damage, mostly to trees.

Area Forecast Discussion National Weather Service Pittsburgh PA 324 PM EDT Mon Jun 24 2019 .SYNOPSIS... Showers and storms will develop late this afternoon and evening before a cold front crosses the Ohio Valley. Tuesday will be cool and dry before warm air and humidity return late in the week. && .NEAR TERM /UNTIL 6 AM TUESDAY MORNING/... The Ohio Valley remains firmly in the warm sector of a sfc cyclone in ern WI. The 12Z PBZ RAOB shows abundant moisture and steepening lapse rates, and a high-altitude freezing level with PWAT unseasonably high. A strong trough is noted in the Plains, while an MCV is evident in satellite imagery near KY. In the wake of a lead shortwave trough this morning (with attendant warm advection-driven showers), brief ridging will aid in heating of the very moist warm sector. There remains some uncertainty if storms will form ahead of a pre- frontal trough that is expected to advance ewd across the Ohio Valley this evening. Any storms that do form ahead of the front will likely become supercellular given the shear/instability profile anticipated. Any such isolated storms will be capable of all hazards: damaging wind gusts, hail (although it will take an especially intense updraft to produce severe hail today, given the freezing level height), tornadoes, and isolated flash flooding (given the expected warm rain processes, rain production will be highly efficient). The higher-certainty evolution is that storms will form along a pre- frontal trough as the MCV advances newd, becoming linear mode as the trough moves into the region early this evening. An organized severe wind event is anticipated with this line. In the wake of the cold frontal passage, there is a possibility for isolated-scattered showers as the cold pool of the H5 wave moves over and assists in the release of weak low-level potential instability. These showers should wane by morning, setting Tue up for a benign, cool day. && .SHORT TERM /6 AM TUESDAY MORNING THROUGH WEDNESDAY NIGHT/... Drier air will spread into the region on Tue. Upper-level flow will transition toward zonal Tue-Wed, with any rain chances tied to low- amplitude waves embedded in the flow. At this time, Tue appears likely to feature cooler air and no rain. It does appear one such low-amplitude wave will interact with a frontal boundary or lake breeze on Wed, with a potential for scattered showers and storms. && .LONG TERM /THURSDAY THROUGH MONDAY/... Rising H5 heights can be expected for the remainder of the week as the Bermuda High amplifies and builds into the central Appalachians. This trend suggests daily increases in temperature through the remainder of the week. The ridge position will be important for assessing any threat for convection during the late-week timeframe. && .AVIATION /19Z MONDAY THROUGH SATURDAY/... Showers and thunderstorms will overspread the region late this afternoon and evening ahead an incoming upper-level trough and sfc cold front. An MCV will move into the area from the Tennessee Valley through this evening, which will further enhance storm initiation while potentially causing sfc winds to back to sely. The storms are expected to form along a broken to solid line while moving from the southwest to the northeast. Strong and erratic winds are likely to occur with any thunderstorm, along with brief reductions in cig/vsby. A weak post-frontal inversion will trap boundary-layer moisture and result in MVFR to IFR cigs overnight. Drier and cooler air moving in from the southwest will erode this inversion and its moisture, allowing for quicker improvement to VFR conditions Tuesday morning. .Outlook... Mostly VFR conditions are expected the rest of the week, though brief cat reductions could occur during storms associated with a weak mid- week disturbance. && .PBZ WATCHES/WARNINGS/ADVISORIES...
