The episode as NWS PBZ wrote it up.
Extreme Drought (D3) conditions continued through the month of September for several counties in Ohio. Conditions worsened to Exceptional Drought in the first week of the month for several counties as very hot and dry conditions persisted. As a result, a burn ban was put into place for the counties that had D3 and D4 conditions.

NWS Pittsburgh, PA wrote its last area forecast discussion before the first event at Aug 31, 7:33 PM EST, 4 hours 27 minutes earlier.
Area Forecast Discussion National Weather Service Pittsburgh PA 833 PM EDT Sat Aug 31 2024 .SYNOPSIS... A crossing front will bring showers and thunderstorms into early Sunday. A big change in the pattern will bring dry and more comfortable conditions next week. && .NEAR TERM /UNTIL MIDNIGHT TONIGHT/... KEY MESSAGES: - The potential for strong to severe severe storms has decreased over the last hour; Severe Watch #666 has been dropped for our entire area. - Remnant showers and storms will continue through the evening as a cold front advances from the northwest. ---------------------------------------------------------------- The threat for severe storms has dropped significantly over the last hour as outflow from earlier convection has warm the mid and upper-levels. Isolated showers and storms will likely continue into the late evening as a cold front advances from northern Ohio. Lightning will be the primary threat. There is also a noted outflow boundary in south Allegheny and extends southwest into Belmont/Monroe County that is producing convection. However,updraft growth is capped at 15kft (just above the freezing level); probability still remains low on convection becoming strong and/or severe. Fog potential will once again build overnight with warm, moist air surrounding the region and light to variable winds. && .SHORT TERM /MIDNIGHT TONIGHT THROUGH MONDAY/... KEY MESSAGES: -Scattered to isolated activity will continue tonight into Sunday morning as a cold front crosses the region. -Noticeably cooler and drier Monday. ------------------------------------------------------------------- Scattered showers and thunderstorms may linger tonight into Sunday morning until the cold front finally exits to the east by early Sunday afternoon. Drier air will filter in behind the surface boundary as well as cooler temperatures. A cool northwest flow is expected on Monday. This should mean dry and much more comfortable conditions. This flow would likely mean increased cloud cover as colder air aloft overspreads the region. Monday's highs will dip down below seasonal averages. && .LONG TERM /MONDAY NIGHT THROUGH SATURDAY/... KEY MESSAGES: - High likelihood for another prolonged dry and seasonable weather pattern. ------------------------------------------------------------------- Long range ensemble analysis favors a prolonged period of dry and seasonable weather as the Upper Ohio River Valley remains under waning NW flow and ridging persists over the Rockies. Variation in potential outcomes increases toward the end of the week depending on potential shortwave trough progression from the west coast over the ridge. If it is able to flatten the ridge Tuesday/Wednesday, the likelihood is for it to advance towards the east coast and offer low probability rain chances and trend area temperature downward after it passes. If it remains stuck over the Pacific NW, the ridge may shunt east and maintain dry weather while causing temperature to rise well above the daily averages. Current forecast remains in between due to ensemble means, but look for these values to trend one way or another as those larger pattern changes are better resolved. && .AVIATION /01Z SUNDAY THROUGH THURSDAY/... Showers and very isolated thunderstorms will continue this evening ahead of a weak surface trough. The main threat from these is heavy rainfall. Convective activity should subside by midnight/04z, but the surface cold front will remain farther to the NW. The combination of moisture convergence and some radiational cooling will foster spreading MVFR to IFR stratus and similar vsby restrictions. Subsidence and diurnal mixing will slowly alleviate conditions Sunday, resulting in VFR conditions (with potential for scattered CU) during the afternoon. .Outlook... Low probabilities (20%) exist for morning stratus near FKL/DUJ Sunday night into Monday morning due to cold advection. High pressure will otherwise foster dry weather and VFR for much of the upcoming work week. Note that cooler mornings may allow for pre-dawn river valley fog. && .PBZ WATCHES/WARNINGS/ADVISORIES...
