A cluster of thunderstorms focused near Cleveland became organized (into a squall line) the evening of June 1st and unleashed strong damaging wind north and west of Pittsburgh. The environment was prime for strong storms to occur: mean layer CAPE was near 1500 J/kg at the time of the squall line and effective bulk shear ranged between 30-35kts.

The episode as NWS PBZ wrote it up.
A cluster of thunderstorms focused near Cleveland became organized (into a squall line) the evening of June 1st and unleashed strong damaging wind north and west of Pittsburgh. The environment was prime for strong storms to occur: mean layer CAPE was near 1500 J/kg at the time of the squall line and effective bulk shear ranged between 30-35kts. Storms lost their intensity as they approached Pittsburgh and a gust front jetted out ahead of the line of convection, approaching an area that lacked robust instability.
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 Pittsburgh, PA wrote its last area forecast discussion before the first event at Jun 1, 1:38 PM EST, 1 hour 52 minutes earlier.
Area Forecast Discussion...UPDATED National Weather Service Pittsburgh PA 238 PM EDT Wed Jun 1 2022 .SYNOPSIS... A cold front will over through the region this evening and stall keeping showers and thunderstorms in the area through Thursday. && .NEAR TERM /THROUGH TONIGHT/... Forecast still in good shape. Watch has been issued for a portion of the region through 10pm. PoPs were slightly modified to better align with current conditions and latest hires model guidance. Mention of severe storms was added as well. A cold front is still projected to slide over the region this evening and stall under zonal flow aloft. Showers and storms are likely as this process occurs. Given the warmth and humidity ahead of the front, model suggestions of 1500-2000 J/kg of sfc-based CAPE look reasonable; however, the better chc for severe weather will lie north and west of Pittsburgh, where 30-40 knots of 0-6km bulk shear may support better storm organization. In addition, dry mid level air may support downburst further south of that corridor; hence, most of the area is under the threat of damaging wind gusts and isolated incidents of large hail. Storm severity and coverage will diminish after sunset with the loss of heating, but at least isolated showers chances will accompany the front through the night. Cooler overnight lows will be realized behind the front, especially north of I-80. && .SHORT TERM /THURSDAY THROUGH FRIDAY/... The mentioned front will continue to slide southeast through the area with a secondary shortwave tracking northeast along the surface boundary. The front will likely hang up in the southern Ohio/northern West Virginia vicinity into Thursday night as it becomes nearly parallel to mid-level flow. This will keep the chance of showers into the southeast through Thursday night. High pressure will continue to move in behind the front with a dry forecast expected on Friday and cooler high temperatures. && .LONG TERM /FRIDAY NIGHT THROUGH TUESDAY/... Models suggest that another shortwave rotating across the southern Great Lakes will finally kick the boundary to the south by Friday. High pressure in continued quasi-zonal flow aloft will then provide mostly dry weather through the weekend, with seasonable but slowly warming temperatures. Rain may return to the forecast by Sunday night/Monday with the next shortwave trough and frontal boundary. This will bring showers and thunderstorms back into the forecast for Monday and Tuesday. && .AVIATION /19Z WEDNESDAY THROUGH MONDAY/... A bkn line of shra/tstms is expected to develop in advance of an approaching cold front through tonight. With respect to tsra timing; high res guidance has slowed, and latest TAFs have been updated to reflect anticipated impact windows via TEMPO groups along with associated MVFR cigs/vis. Widespread MVFR/IFR is then expected to develop from N-S after FROPA tonight/Thu morning provided llvl moisture within nwly flow, with scattered shra persisting through the remainder of the period. .Outlook... Restrictions are expected Thu as low pres moves along the front. && .PBZ WATCHES/WARNINGS/ADVISORIES... PA...None. OH...None. WV...None. && SYNOPSIS... NEAR TERM... SHORT TERM... LONG TERM...
