The episode as NWS PBZ wrote it up.
A few thunderstorms formed along an advancing cold front during the afternoon. The combination of dry air aloft and sufficient deep layer shear allowed for the generation of a few severe thunderstorms. One of these storms occurred in Columbiana County, leading to some tree damage.

NWS Pittsburgh, PA wrote its last area forecast discussion before the first event at Jun 3, 1:47 PM EST, 43 minutes earlier.
Area Forecast Discussion National Weather Service Pittsburgh PA 247 PM EDT Sun Jun 3 2018 .SYNOPSIS... Showers and thunderstorms will cross with a cold front through this evening. Brief high pressure will return dry and seasonable conditions Monday before another disturbance approaches Tuesday. && .NEAR TERM /THROUGH TONIGHT/... Cold front associated with an upper trough over the Great Lakes will cross the upper Ohio valley through this evening. Some clearing ahead of this boundary has allowed for modest destabilization across the region, which, in addition to the available speed and directional shear, could support some strong/marginally severe thunderstorms. This lines up well with SPCs marginal risk. Continued to make only minor adjustments to the forecast based on newest hi res guidance. Otherwise, front should be east of the region before midnight. Building surface ridge will support clearing skies, though some lingering clouds may be possible closer to the upper trough to our north. Lows will be near seasonal averages. && .SHORT TERM /MONDAY THROUGH WEDNESDAY/... Building ridge should keep most of the region dry until later Tuesday when the upper trough over Quebec sinks southward. Some scattered showers will be possible as a shortwave and associated cold front sag southward across the region, with seasonably cool temperatures expected in this systems wake through Wednesday. && .LONG TERM /WEDNESDAY NIGHT THROUGH SATURDAY/... Expect dry conditions early in the long term but model discrepancies continue as shortwaves riding overtop the building central CONUS ridge are timed differently. Will keep PoP chances near climo and temperatures close to a blend of guidance. && .AVIATION /19Z SUNDAY THROUGH FRIDAY/... Expect brief MVFR/IFR restrictions as showers and thunderstorm cross with the cold front this evening. While strong storms with gusty wind are possible, this is not reflected in any TAF at this time due to coverage and confidence. The front will sweep east by midnight. Lower surface dewpoints should preclude much in the way of fog late tonight, but MVFR ceilings may follow the front for a bit, mainly east of Pittsburgh. Most terminals should achieve VFR once again by the end of the TAF period. OUTLOOK... Restrictions will be possible again with a Tuesday cold front. && .PBZ WATCHES/WARNINGS/ADVISORIES... MD...None. OH...None. PA...None. WV...None. &&
