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 Jul 8, 2:54 PM EST, 1 hour 51 minutes earlier.
AREA FORECAST DISCUSSION National Weather Service Wilmington OH 354 PM EDT Thu Jul 8 2021 .SYNOPSIS... A cold front will pass through the area this evening providing showers and storms. High pressure will bring dry and cooler weather on Friday before another frontal system returns stormy weather to the forecast this weekend. && .NEAR TERM /UNTIL 6 AM FRIDAY MORNING/... Surface cold front draped from northwest Ohio back through southern Illinois will continue to slowly sag southeast this evening into tonight just ahead of a digging mid- level trough. Showers and storms will continue along and ahead of the front this evening, with coverage and intensity waning heading toward midnight. While radar trends seem to indicate less intensity moving forward, have held PoPs in the likely category for a few more hours due to boundary interactions from convection currently moving east out of Indiana. Will also keep mention of potential for strong to damaging winds in the HWO based on these storms in Indiana. Confidence is decrease in this scenario however. Temperatures will start to drop tonight behind the front, with low temperatures reaching the low 60s northwest to upper 60s southeast. && .SHORT TERM /6 AM FRIDAY MORNING THROUGH FRIDAY NIGHT/... Surface high pressure will usher in cooler weather and lower dewpoints Friday into Friday night. Meanwhile the cold front, which will stall over the Tennessee Valley Friday, will return northeast as a warm front late in the short term period. First signs of this will be increasing high clouds late Friday night as west-southwest flow brings warm moist air back toward the Ohio Valley. High temperatures will range from the mid 70s northwest to low 80s southeast on Friday, with lows dipping into the low 60s Friday night. && .LONG TERM /SATURDAY THROUGH THURSDAY/... Short wave energy digging down across the upper Midwest will help an upper level low develop over the central Plains Sunday into Monday. At the surface, an associated surface low will lift slowly north across the mid Mississippi Valley Saturday and Sunday while a warm front extending southeast from the low pivots slowly north across the Ohio Valley Region. Increasing southwesterly low level flow ahead of the low will lead to good moisture transport up into our area with PWs pushing up to around 150 percent of normal through the weekend. Good convergence associated with the front will lead to an increasing chance of showers and thunderstorms southwest to northeast across our area Saturday into Saturday night. Heavy rainfall will be possible at times and depending on how progressive the front is, we may end up with some hydro issues Saturday into Sunday. The upper level low will then shift slowly north across the western Great Lakes Monday into Tuesday with our area remaining in persistent moist, southwest flow. This will lead to continued chances for diurnally enhanced showers and thunderstorms. The flow aloft will then transition to a somewhat more progressive westerly pattern Wednesday into Thursday but it will still be tough to rule out at least some lower end chances for pcpn through the end of the long term period given the potential for some embedded mid level short waves moving through in the flow. High temperatures on Saturday will only be in the mid 70s to around 80s degrees. We will then warm back up through next week with highs by mid week back into the mid to possibly upper 80s. && .AVIATION /20Z THURSDAY THROUGH TUESDAY/... Thunderstorms ongoing near DAY/CMH/LCK terminals to start the TAF period, with activity moving toward CVG/LUK/ILN over the next couple of hours. A few of the strongest storms will likely produce locally strong wind gusts, so will continue to monitor closely to add these to the TAFs at the appropriate terminals. Otherwise, high-res guidance now focusing on this convection reaching an intensity peak this afternoon and early evening, then decreasing a bit heading into the late evening. Cold front passes through with a wind shift to the northwest after midnight, followed by potential for MVFR clouds to develop and linger Friday morning. .OUTLOOK...Thunderstorms possible Saturday through Monday. && .ILN WATCHES/WARNINGS/ADVISORIES...
