A broken line of thunderstorms moved across this area of the Ohio Valley just ahead of an approaching cold front. While thunderstorms were generally moving fast enough to avoid flooding issues, some locations received multiple rounds of heavy rainfall as multiple convective segments moved across, and in some instances trained across the same area.

The episode as NWS PBZ wrote it up.
A broken line of thunderstorms moved across this area of the Ohio Valley just ahead of an approaching cold front. While thunderstorms were generally moving fast enough to avoid flooding issues, some locations received multiple rounds of heavy rainfall as multiple convective segments moved across, and in some instances trained across the same area. This led to isolated flash flooding in Ohio and Pennsylvania.

NWS Pittsburgh, PA wrote its last area forecast discussion before the first event at Jun 26, 7:40 PM EST, 45 minutes earlier.
Area Forecast Discussion National Weather Service Pittsburgh PA 840 PM EDT Sun Jun 26 2022 .SYNOPSIS... Showers and storms will end tonight with the passage of a cold front. Cool and dry weather will then prevail to start the work week. && .NEAR TERM /UNTIL 6 AM MONDAY MORNING/... Frontal boundary is now in the general vicinity of a CLE/CMH line. Storms out ahead have organized in lines as cold pools merge, and these lines will work their way across the CWA through midnight. While the storms have had 1000-2000 J/kg of MLCAPE to work with this afternoon, strong wind has been hard to come by from these storms as overall flow and DCAPE remain low. The storms remain efficient rainfall producers though, with the 1.8 inch PWAT value on the 00Z PBZ sounding evidence of the deep moisture in place. In particular, portions of Mercer and Noble Counties have received between 1 and 2 inches of rain due to short periods of training storms. The threat of heavy rain and perhaps flooding will linger for a few more hours this evening, although storm motion should be sufficient to prevent issues in most cases. Will continue with relatively high PoPs for showers and storms through the evening as the front approaches and crosses. Shower coverage will decrease from the west this evening and eventually clear out of northern West Virginia by morning after cool, dry northwest flow comes in after FROPA. Lower temperature and dewpoint will be noticeable in some areas by sunrise. && .SHORT TERM /6 AM MONDAY MORNING THROUGH TUESDAY/... Very pleasant weather is expected on Monday and Tuesday as dry northwest flow prevails behind the departing trough and cold front. Highs both days will be in the 70s, about 5 degrees below climatological values. Lows will also be cool, with temps dropping into the 50s at night... though some typically cooler spots may very well descend into the 40s on Tuesday night. && .LONG TERM /TUESDAY NIGHT THROUGH SUNDAY/... Sfc high pressure is expected to remain across the region as the upper flow becomes more zonal by mid to late week. This should result in continued dry weather, with a warming trend. Precipitation chances increase by late week and into the weekend as warm, humid air returns to the Upper Ohio Valley. && .AVIATION /01Z MONDAY THROUGH FRIDAY/... Broken lines of thunderstorms ahead of an approaching cold front will work their way across the area through midnight. Have timed two-hour windows of likely greatest impact in the TAFs, although some recent weakening of the storms may not allow the depicted IFR conditions to be realized in a couple of cases. Visibility-restrictive heavy rain and lightning are the main impacts of the storms. The threat of thunder should largely end at all terminals by midnight, although MVFR ceilings and a few showers may remain possible through and just after FROPA. Behind the front, cool and dry advection on W, then NW flow will break clouds overnight, leading to a return of VFR conditions. Expect fog to be prevented by the dry advection and the still- mixed boundary layer. Past sunrise, a pleasant VFR day is forecast, with a northwest breeze gusting to around 15 knots at times by midday. .Outlook... VFR is expected to prevail through mid-week under high pressure. && .PBZ WATCHES/WARNINGS/ADVISORIES... PA...None. OH...None. WV...None. &&
