The episode as NWS PBZ wrote it up.
Southwest flow during the late morning and early afternoon hours of September 21st advected warm, high dewpoint air into the region that was unusual for late September. Late afternoon thunderstorms generally stayed closer to Lake Erie, but a cluster of storms managed to form in central Ohio after sunset, working their way east thereafter. These storms had strong enough wind gusts to create a few instances of damage.

NWS Pittsburgh, PA wrote its last area forecast discussion before the first event at Sep 21, 7:24 PM EST, 25 minutes earlier.
Area Forecast Discussion...UPDATED National Weather Service Pittsburgh PA 824 PM EDT Wed Sep 21 2022 .SYNOPSIS... Showers and storms are likely overnight along and ahead of an advancing cold front. Lingering showers on Thursday will give rise to a cool but dry end of week. && .NEAR TERM /UNTIL 6 AM THURSDAY MORNING/... Moisture and instability both remain present owing to a lack of aftn thunderstorms through much of the region. Storms are beginning to develop in the area of Columbus as synoptic forcing acts on an unstable and moist warm sector sprawled across central and ern OH. As this forcing for ascent spreads ewd across the Upper OH Valley, convective coverage may increase overnight in two waves: first as a cluster of storms in the 0100-0600 UTC timeframe, and second late tonight as less-intense showers and storms as the cold front currently crossing MI advances sewd. Despite the atypical timeframe of these convective storms and the shallow stable sfc layer, a non-zero threat for severe weather still exists, especially from this first round of storms, since the sfc inversion initially remains shallow and the airmass is relatively unmarred by afternoon storms. && .SHORT TERM /6 AM THURSDAY MORNING THROUGH FRIDAY NIGHT/... The entire region on Thu will be embedded in post-frontal nwly flow. The thermal contrast between warm Lake Erie and cool land airmass will support stratocu and showers across nern OH and nwrn PA. Radiational cooling will be optimized Thu night as wind slackens and sky clears, leading to overnight minima some 10F below seasonal normal, and into the 30s in the ridges. Friday will be defined by clear and cool conditions amid high pressure. Temperature will again remain around 10 degrees below average with renewed possibility of temps in the 30s Fri night at higher elevations. && .LONG TERM /SATURDAY THROUGH WEDNESDAY/... There is moderate confidence in the maintenance of a cool pattern through the weekend and early next week as Fiona is absorbed into an ern-CONUS trough along ern Canada. This persistent ern trough may bring shower chances late in the weekend and early next week in the proximity of a passing surface low. && .AVIATION /00Z THURSDAY THROUGH MONDAY/... CAPE remains considerable in the 00Z PIT RAOB, and storms are beginning to blossom west of ZZV as jet dynamics enhance ascent overnight. Broader coverage of tstms is expected across the Upper OH Valley in the 01-06Z period, after which an advancing cold front will lead to convective overturning and widespread showers and storms for a brief period in the 08-12Z period. In the wake of the cold front, gusty nwly wind is anticipated during the day Thu, with potential for lake-enhanced showers through mid-day before high pressure dominates. MVFR conditions are anticipated post-dawn Thu amid a cold-air advection regime. .Outlook... High pressure and VFR conditions can be expected much of the weekend. The potential for restrictions returns with a cold front on Sun. && .PBZ WATCHES/WARNINGS/ADVISORIES... PA...None. OH...None. WV...None. && Kramar
