The episode as NWS PBZ wrote it up.
A narrow warm sector along and south of a nearly stationary boundary saw showers and thunderstorms develop in the afternoon hours. Training along the boundary mostly resulted in a flash flooding threat, though moisture pooling ahead of the front supported MLCAPE values reaching 1000 J/kg, and 30-40 knots of effective shear supported some storm organization for a damaging wind and embedded tornado threat with locally backed surface wind.

NWS Pittsburgh, PA wrote its last area forecast discussion before the first event at Jun 22, 1:00 PM EST, 2 hours 31 minutes earlier. Its key messages:
Area Forecast Discussion National Weather Service Pittsburgh PA 200 PM EDT Mon Jun 22 2026 .WHAT HAS CHANGED... Updated aviation section for 18z TAF package. Slight increase in chance for tornadoes with any severe storms this afternoon especially over northern WV and parts of southwestern PA. Uncertainty remains regarding where the axis of heaviest rainfall sets up today, but trends indicate it is likely south of Pittsburgh, potentially in northern West Virginia. && .KEY MESSAGES... 1) Rounds of showers and thunderstorms are expected today through this evening. Risks for isolated severe thunderstorms and instances of flash flooding remain. 2) Dry conditions and seasonable temperatures are expected through midweek. && .DISCUSSION... KEY MESSAGE 1... This afternoon, moisture maximizes in areas south of Pittsburgh, with precipitable water maximizing in the 1.6 to 1.8 inch range. Despite abundant cloud cover, surface-based CAPE is expected to build above 1000 J/kg southeast of a rough IDI/PIT/ZZV line (40% or greater chance on HREF progs). Expected 0-6km shear of 25-35 knots should be sufficient for storm organization into clusters/lines ahead of the advancing cold front. Damaging winds are the most likely severe threat in this scenario. Tornadoes are the secondary threat where convection could potentially take advantage of locally backed flow in the vicinity of the warm sector, most likely southeast of Pittsburgh, where the SPC Slight (level 2 of 5) Risk of severe thunderstorms exists. More isolated potential exists over the rest of the region for damaging gusts. The noted precipitable water levels suggest efficient rain- producing storms, as does decent low-level sounding saturation and warm cloud depths. Fast storm motion should help to limit the heavy rain threat to some degree unless training occurs. CAMS are also still in disagreement as to where the heaviest corridor of precipitation may set up and REFS/HREF suggesting maximum total rainfall potential of 2 to 3 inches in the worst case scenario. Such rainfall totals could cause localized flood issues. If later CAM runs focus heavy rainfall more favorably on a region (most likely target zone: northern West Virginia), then a short-fuse Flood Watch could be considered. The passage of the cold front tonight should decrease coverage of showers and storms from west to east, likely pulling out of the southeastern ridges overnight. A developing subsidence inversion will likely lock in low-level moisture, producing stratus and fog late tonight. KEY MESSAGE 2... High pressure builds in the wake of the departing low, and after a potentially dreary sunrise Tuesday, dry weather and a trend towards seasonable temperatures is expected through Wednesday. High values should reach the upper 70s to around 80 by midweek. && .AVIATION /18Z MONDAY THROUGH SATURDAY/... Flow has decreased near track of surface low and light winds have allowed IFR stratus to persist at KDUJ and KBVI. While would expect some improvement likely to MVFR by evening, the ceilings will lower again after dark to IFR in most locations. Showers and thunderstorms will be most prevalent in the central and southern TAF sites but associated wind gusts. Severe gusts are unlikely with moist airmass but brief LIFR downpours are expected. Isolated tornadoes possible until 22-00z. Activity will decrease from west to east after 00Z as a cold front crosses. However, a developing subsidence inversion should lock in low-level moisture, producing IFR conditions in stratus and fog after sunset and continuing through the night. These restrictions should be in place through about 15Z. Outlook... VFR conditions are likely to return Tuesday by 15z after the morning stratus burns off. The next chance for widespread restrictions will be Thursday with increased precipitation potential. && .PBZ WATCHES/WARNINGS/ADVISORIES... PA...None. OH...None. WV...None. && DISCUSSION...CL/Lupo AVIATION...Craven
