At the surface, a low moved north-northeastward from northwestern IN to southwestern Lower MI during the early afternoon through late evening of the 24th. This allowed the trailing cold front to sweep eastward across IN toward the IN/OH border, while the warm front drifted northeastward across northern OH, much of southern Lower MI, western and central Lake Erie, and portions of northwest PA.

The episode as NWS CLE wrote it up.
At the surface, a low moved north-northeastward from northwestern IN to southwestern Lower MI during the early afternoon through late evening of the 24th. This allowed the trailing cold front to sweep eastward across IN toward the IN/OH border, while the warm front drifted northeastward across northern OH, much of southern Lower MI, western and central Lake Erie, and portions of northwest PA. Within the warm and moist sector, isolated to scattered multicell and occasional supercell thunderstorms moved generally northeastward or eastward across northwest and north-central OH during the late afternoon through early evening hours. These storms produced isolated straight-line wind damage, very isolated severe hail, and a brief tornado as the storms encountered moderate effective bulk shear and MUCAPE, respectively. The briefly tornadic supercell in Lorain County appears to have coincided with favorably-low mixed layer LCL's and an increase in surface-based ESRH tied to the development and strengthening of a southwesterly nocturnal low-level jet at and near 850 mb.

NWS Cleveland, OH wrote its last area forecast discussion before the first event at Sep 24, 2:34 PM EST, 36 minutes earlier.
Area Forecast Discussion National Weather Service Cleveland OH 334 PM EDT Tue Sep 24 2024 .SYNOPSIS... Low pressure moves northeast across the Great Lakes region through Thursday and will drag a weak cold front across the area late Wednesday into early Thursday. High pressure enters from the northwest on Thursday. && .NEAR TERM /THROUGH WEDNESDAY NIGHT/... Surface warm front continues lift across the region as the parent low pressure moves northeastward across Lower Michigan this evening. Shower and thunderstorm coverage has decreased for the time being, however, we're beginning to see some redevelopment of showers and storms across Northern Indiana. Can't rule out strong to severe thunderstorms, especially across the I-75 corridor, as current mesoanalysis indicates a favorable environment with MLCAPE values of 1000+ J/kg coupled with bulk shear magnitudes of 30-35 kts. As such, portions of Northwest Ohio remain under a Marginal Risk (Level 1/5) for Severe Weather through this evening. Showers and thunderstorms will diminish in coverage and intensity later this evening as the surface low continues to lift north. Low stratus/patchy fog will move overhead tonight given recent rainfall/lingering low level moisture and calm winds. Upper level trough will continue to dig eastward through Wednesday with lingering shower and thunderstorm chances east of I-71 through Wednesday night. Overnight lows tonight will generally settle in the low 60s. Slightly warmer Wednesday afternoon with highs in the mid 70s. Cold front will begin to cross the region Wednesday night into Thursday morning which will allow for lows to dip into the upper 50s in NW Ohio and lower 60s elsewhere. && .SHORT TERM /THURSDAY THROUGH FRIDAY NIGHT/... There will be some lingering post-frontal showers Thursday morning in NE OH and NW PA but will be ending by mid-day. During the day Thursday, high pressure will build in ushering in dry weather for the next 24-36 hours. On Friday, an upper level low will interact with Tropical Storm Helene as it moves inland from the Gulf Coast. This will bring moisture northward from as the storm wraps around the upper level low. There is uncertainty of how far north the moisture will be as the system will stall out in the Tennessee/Ohio River Valleys. With that, PoPs will be similar to previous forecasts with 40 percent in the southwestern counties and around 30 percent for the northeast counties for Friday evening. Highs will generally be in the high 70s for Thursday and Friday and lows in the upper 50s, low 60s each night. The high temperatures may be limited depending on if there are any showers in the southern counties for Friday. && .LONG TERM /SATURDAY THROUGH TUESDAY/... Going into Saturday the upper level low across the mid-Mississippi River Valley will start to meander northeastward into the Ohio River Valley region. There is still uncertainty on the location and strength of the system as it will be slow moving, but will continue to influence the weather for the region through the weekend. As a result, expect dreary weather into the beginning of next week with overcast skies, low-end chance of PoPs, and a few thunderstorms. Temperatures will trend towards normal for the area, with highs in the mid to upper 70s on Saturday and low 70s by Tuesday. Lows will follow a similar pattern, being in the low 60s, upper 50s on Saturday and by Tuesday everyone will be in the mid 50s. && .AVIATION /18Z Tuesday THROUGH Sunday/... Coverage of showers and thunderstorms has decreased as the warm front has lifted north of the region. Isolated to scattered thunderstorms are beginning to approach terminals from the southwest this afternoon and will likely impact western terminals (TOL/FDY/MFD) within the next few hours. Elsewhere, there is less confidence in timing and coverage of showers and thunderstorms but generally have showers with vicinity thunderstorms 22Z onward for CLE and points eastward. Low ceilings and the potential for some patchy fog/mist will spread across the region overnight tonight with IFR likely through daybreak Wednesday. Generally southerly flow between 8-10 knots continues this afternoon and early evening. Winds decrease to 5 knots or less while turning southwesterly overnight tonight. Favorable downsloping setup at ERI in southerly flow this afternoon and evening will keep winds elevated at 10-15 knots with gusts 20-25 knots possible. Outlook...Strong northeast winds are expected across the region on Friday. Non-VFR may return in showers and thunderstorms this weekend. && .MARINE... A Small Craft Advisory will be in effect from 21Z Tuesday to 12Z Wednesday morning due to downsloping winds in the eastern basin of Lake Erie. Winds will be out of the southeast at 15 to 25 knots overnight before subsiding Wednesday morning as winds shift to be more southwesterly at 10 to 15 knots. A cold front will move across the lake Wednesday afternoon and the winds with veer to be out of the northwest, but with a weaker pressure gradient, will only be 5 to 10 knots. Through the day on Thursday, the winds will shift out of the northeast as high pressure builds into the region. The pressure gradient will then tighten as Tropical Storm Helene moves northward from the Gulf Coast during the day on Friday. Winds will be east-northeasterly and increase to 15 to 25 knots for most of the central and western basins of Lake Erie and therefore, a strong chance for a Small Craft Advisory to be needed for Friday into Saturday. && .CLE WATCHES/WARNINGS/ADVISORIES...

GriffinThe Cleveland radar (KCLE), 120 km away, was scanning. The volume nearest the first event began at 20:09 UTC.
2 thunderstorm wind, 1 hail, 1 tornado. Local standard time, as filed.
Power pole broken along OH-105 on north side of Elmore.
Tree limbs downed along West Elmore Eastern Road in Elmore.
Hail up to quarter-size in Tiffin.
This very brief EF0 tornado with estimated peak winds of 75-mph began just west of Gore Orphanage Road in Kipton. As the tornado moved northeastward, it removed portions of metal siding and roofing at a farmstead. Among the metal debris, some was twisted, some was blown into a separate structure's west side at the farmstead, and some was scattered northeastward into a field east of Gore Orphanage Road. The tornado dissipated soon after crossing the aforementioned road.
