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 Jun 9, 3:04 PM EST, 3 hours 9 minutes earlier.
AREA FORECAST DISCUSSION National Weather Service Wilmington OH 404 PM EDT Tue Jun 9 2020 .SYNOPSIS... Low pressure will exit to the northeast this evening, but will be following by another low pressure system and additional storm chances on Wednesday. High pressure will provide cooler and drier weather for late week into the weekend. && .NEAR TERM /UNTIL 6 AM WEDNESDAY MORNING/... Remnants of Cristobal are heading north along the Mississippi River this afternoon, while surface high pressure remains off the Atlantic coast. Increasing southerly flow accompanying the tropical system will continue to pump in a very humid airmass through the near term. High-res models push the current band of storms to the north and northeast through sunset, with decreasing instability in the wake of the precipitation as temperatures drop into the upper 70s. In the muggy air behind the showers, expecting low temperatures overnight only to dip into the low 70s. Decided to keep slight chance POPs in the forecast overnight, since it won't take much in the tropical environment to form some weak convection. && .SHORT TERM /6 AM WEDNESDAY MORNING THROUGH WEDNESDAY NIGHT/... Main story Wednesday will be increasingly unstable airmass meeting up with a negatively tilted shortwave heading up the ridge axis currently in place over the East Coast. At the surface, a cold front/dry line will slice through the forecast area during the late afternoon hours. Timing of this line of convergence is still a bit uncertain with the guidance. Have bracketed the time of peak concern to be from 18Z through just after 00Z, with a quick end to the precipitation behind the main line along the front. Based on several emerging mesoscale factors, including SBCAPE values of 2000-3000 J/kg, 35-45kts of 0-6km bulk shear, and 20-30kts of 0-1km bulk shear, there is growing concern for severe storms with damaging wind, large hail, and tornadoes as well. In fact, STP values exceeding 3 in west central through central Ohio provide some alert for the potential for strong tornadoes during the late afternoon through early evening hours. Main question will be coverage for storms, as well as how long the storms remain discrete along the front. Behind the front, rapid drying will end the storm threat and usher in cooler air for the rest of the short term period. && .LONG TERM /THURSDAY THROUGH TUESDAY/... Most concern in the long term /after a quiet and enjoyable Thursday and Friday/ will be where and when closed/cutoff low forms in the Great Lakes later in the weekend and into early next week. There is considerable uncertainty in not only where/when this forms among the deterministic and ensemble members, but also the impacts on the sensible weather. There is high confidence this entire period will feature below normal temperatures and little threat of hazardous weather. However, the most problematic part of the forecast centers around Sun/Mon/Tues with a rather large degree of uncertainty on daytime high temperatures/shower potential/and cloud cover should the closed low develop right over the ILN CWA, a possibility in a handful of the runs viewed from 09.00Z and 09.12Z. For right now, will keep low rain chances on Tuesday /which has the best ensemble agreement of those three days/ and leave potential adjustments to Sunday/Monday with upcoming shifts who may need to introduce diurnally driven shower potential. Same logic for temperatures - if closed upper low parks right over the ILN CWA on Sunday/Monday, temperatures may need to be dropped significantly from current forecast highs - and these days are recognized as having very large spreads in temperatures in EPS/GEFS data. && .AVIATION /18Z TUESDAY THROUGH SUNDAY/... Main threat within the TAF period will be thunderstorm potential this afternoon into early evening along gusty southerly winds. Stayed with VCTS through near term period, though higher resolution models depict a northwest to southeast oriented band pushing through CVG/LUK, then DAY/ILN, then CMH/LCK in the 20-24Z time frame. Due to timing differences between models along with uncertainty with how much lightning will be present, will adjust as details emerge. Tonight, guidance continues to depict a very moist environment leading to lowering of ceilings below 3000 feet starting around sunrise and continuing for a few hours in the morning. Following burn-off, and leading to the end of the TAF period, focus turns to increasing thunderstorm potential after noon Wednesday. OUTLOOK...Thunderstorms are possible on Wednesday. Wind gusts to 30kts are also possible on Wednesday. && .ILN WATCHES/WARNINGS/ADVISORIES... OH...None. KY...None.
