Developing showers and thunderstorms produced a brief landspout north of Sherwood, OH.
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 Northern Indiana wrote its last area forecast discussion before the first event at Jul 1, 2:51 PM EST, 1 hour 51 minutes earlier.
Area Forecast Discussion National Weather Service Northern Indiana 351 PM EDT Sat Jul 1 2023 .SYNOPSIS... Issued at 340 PM EDT Sat Jul 1 2023 Showers and thunderstorms are expected late this afternoon through tonight. Heavy rainfall is the greatest concern, with rain rates of 1 inch per hour or more. Locally damaging wind gusts from the strongest, most developed, storms is possible as well. Widespread severe weather is not expected. Wet weather lingers Sunday. && .SHORT TERM...(This Evening through Sunday) Issued at 340 PM EDT Sat Jul 1 2023 A decaying MCS this morning brought welcome rain to the area this morning and left an outflow boundary for redevelopment. Satellite and composite radar suggest this boundary is oriented west-east from about Kankakee, IL to Ottawa, OH. Severe weather ingredients remain favorable (especially CAPE and moisture, while shear is marginal). Synoptic forcing improves toward 00z (8pm EDT) tonight when the 500- mb jet ramps up over central Indiana. Ahead of this feature, perturbations ejecting from the positively-tilted trough over western Iowa, could also spark scattered storms over our area, especially in the vicinity of the outflow boundary. But because of jet dynamics displaced to the south, widespread severe storms will fail to materialize locally. However, step low- level lapse rates, deep cloud moisture, and tall CAPE profiles suggest a wet microburst potential with the tallest cores. Flooding rain is also expected under training storms, as evidenced by locations this morning seeing rain rates of 1" per hour. Training storms were also noted over southern Wisconsin along a stationary front, which extends east into central Michigan. While CAMs are highly variable in timing and coverage, many members suggest storms ignite over far southern MI, far northern IN, in the vicinity of the lingering outflow boundary or stationary front. Wind parallel to either boundary increases the flooding risk from training storms, but upper-level support is lacking and shear is marginal (20-25 knots 0-500mb), so once again storm coverage is uncertain. On Sunday, the aformentioned trough tracks east-northeast overhead keeping rain in the forecast. I did roll the dice and reduce morning POPs, thinking that there would be a lull after pre-dawn convection. Rain coverage is questionable according to the CAMs, so Sunday's forecast will likely need to be re-assessed late tonight and Sunday morning in this messy convective pattern. && .LONG TERM...(Sunday Night through Saturday) Issued at 340 PM EDT Sat Jul 1 2023 Dry weather is favored, but not guaranteed Monday afternoon through Wednesday morning. Generally speaking, the trough moves over the eastern Great Lakes and high pressure briefly passes by during that time. Zonal flow remains aloft, so continued soupy conditions are expected, but in the absence of a trigger, not sure what the model guidance is keying in on for pop-up storms. POPs have been reduced; a step in the right direction. Instead, the best chance for rain and storms in the long-term forecast is with a cold front Wednesday night through Thursday morning. Thereafter, perhaps a break in the active convective pattern and reduced/improved drought conditions after all these rain chances. && .AVIATION...(For the 18Z TAFS through 18Z Sunday Afternoon) Issued at 123 PM EDT Sat Jul 1 2023 A broad upper trough shifts eastward toward the area from the west and, coupled with the influx of moisture, our chance for showers and thunderstorms will continue through the ensuing 24 hours. The difficulty comes when trying to nail down exact timing for stronger episodes of such, especially since morning showers and storms likely ate into the chance for greater instability to build. Storms will have a chance to form along various composite boundaries that move through the area, but the main hazard will continue to be heavy rain and damaging winds. With this in mind, flight conditions will be adversely affected as showers and storms move through with the extra low level moisture they provide. As such, chances for MVFR and IFR conditions will be possible within heavy rain's visibility reduction opportunities and lowered ceilings before and after storms. Additionally, and especially for areas that receive rain, fog will become a possibility as the temperature drops back towards the dew point again overnight. Winds will largely be affected by the small scale shortwaves moving through and will allow for initially southwesterly winds veering around to northerly and then back to easterly before doing the same progression again with the next shortwave coming through. Winds become lighter overnight, but then pick up in intensity again Sunday, all the while, staying below 20 kt gusts. && .IWX WATCHES/WARNINGS/ADVISORIES... IN...NONE. MI...NONE. OH...NONE.

PBMThe Northern Indiana radar (KIWX), 96 km away, was scanning. The volume nearest the first event began at 21:41 UTC.
1 tornado, 1 thunderstorm wind. Local standard time, as filed.
EF0 landspout tornado briefly touched down north of Sherwood, Ohio. About two dozen slate shingles were removed from a barn. Also, a large limb and several small limbs were downed. The tornado tracked through a nearby cornfield and dissipated as it tracked northeast into a wooded area.
The public reported small tree limbs were blown down and shingles torn off a barn at a property off U.S. 127.
