The episode as NWS ILN wrote it up.
Scattered thunderstorms developed in the afternoon along a remnant frontal boundary that was situated over the Ohio Valley.
The local office's own words before the first event, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.
NWS Wilmington, OH wrote its last area forecast discussion before the first event at May 26, 2:32 PM EST, 37 minutes earlier.
AREA FORECAST DISCUSSION National Weather Service Wilmington OH 332 PM EDT Sun May 26 2019 .SYNOPSIS... Showers and thunderstorms will affect the region this evening as a front drops south into the area. The front will lift back north on Memorial Day keeping scattered storms in the forecast. Warm and humid conditions and unsettled weather will be the rule into next week with a chance of thunderstorms each day. && .NEAR TERM /UNTIL 6 AM MONDAY MORNING/... Mid level shortwave evident on water vapor imagery tracking across Southern IL moving into Southern IN. Thunderstorms are increasing in coverage in the moderately unstable airmass over the Ohio Valley ahead this shortwave. Bulk shear of 45 to 50 kts is resulting in organized storms and rotating updrafts. Rotating supercell over Hocking county has produced 3 inch diameter hail. Threat for severe weather will continue into this evening. Damaging winds and large hail are the primary threats with generally weak low level hodographs. With the passage of this shortwave - thunderstorms will diminish early this evening with the front slipping south of the Ohio River and stalling out overnight. Low clouds and some fog will likely develop overnight in the moist environment along and north of the boundary. Overnight low temperatures to range from near 60 north to the mid 60s south. && .SHORT TERM /6 AM MONDAY MORNING THROUGH MONDAY NIGHT/... Another mid level shortwave to track through the Ohio Valley with the front lifting back north as a warm front Monday afternoon. Moderate instability develops late in the day across the west as the warm front begins to pivot north. Severe storms will again be possible in this region. Mondays highs to range from the upper 70s north to mid 80s south. Mid level ridge builds into the region Monday night with the front pushing north of the region into the Great Lakes. Storm chances will diminish across the south but will keep a slight chance across the far north. Expect mild lows Monday night in the mid and upper 60s. && .LONG TERM /TUESDAY THROUGH SUNDAY/... An active weather pattern will continue through the coming week. The Ohio Valley will remain on the northern periphery of a mid-level ridge through Thursday, with occasional chances for storms expected as disturbances move eastward through the flow. As this occurs, a surface frontal boundary is expected to remain somewhere in the area, though generally favored to be just north of the ILN CWA, keeping the region within an area of warm and moist conditions. As it appears right now, this boundary should almost certainly be north of the area on Tuesday, leading to the CWA being largely warm sectored and capped, and unlikely to be a source of convective development. Nonetheless, there are some indications that convection developing closer to the front may propagate southward into the forecast area during the afternoon/evening, warranting some 20-30 PoPs north of Interstate 70. Tuesday should also be the warmest day of the extended period, with highs in the mid 80s to lower 90s. As the front oscillates slightly southward on Wednesday, and a shortwave approaches from the west, temperatures should moderate slightly -- but chances for storms will also increase. A more pronounced shortwave is expected to move into the area on Thursday, along with a further southward progression of the surface boundary. This will lead to what appears to be the greatest chance for precipitation during peak diurnal timing. Beyond Thursday, there are timing differences in the models regarding the progression of a secondary trough moving across the Great Lakes -- the 00Z ECMWF, for example, is a little more amplified and slower with its eastward motion. Thus, there is much less certainty with the precipitation forecast for Friday and beyond. This is especially true heading into the weekend, when flow will set up in more of a pseudo-zonal orientation, with quicker shortwaves that are very hard to time out. Temperatures from Thursday through the weekend should be slightly cooler than earlier in the week, but generally still near to slightly above normal. && .AVIATION /19Z SUNDAY THROUGH FRIDAY/... Thunderstorms will increase in coverage in the moderately unstable airmass over the Ohio Valley ahead of a shortwave located over Southern Illinois. Bulk shear will support organized storms with damaging winds and large hail possible this aftn into early evening. Have a tempo group in TAFs for time when the best threat for storms is forecast. Have MVFR ceilings and IFR vsbys in the storms but brief IFR ceilings are possible. With the passage of this s/w - thunderstorms will diminish early this evening with the front slipping south of the Ohio River and stalling out overnight. Fog and low clouds are expected to develop north of the front. The best chance for IFR conditions will occur across the southern TAF sites. Vsbys will improve and expect ceilings to lift to VFR by late morning. The front to lift back north as a warm front Monday with additional thunderstorms expected. OUTLOOK...Thunderstorms possible Monday afternoon into Monday night, then again Wednesday and Thursday. && .ILN WATCHES/WARNINGS/ADVISORIES... OH...None. KY...None.
