The episode as NWS IND wrote it up.
Scattered to numerous evening thunderstorms tracking mainly eastward across central Indiana, included 5 severe cells that altogether produced widely scattered wind damage. More pronounced rotation was exhibited by a few storms crossing northeastern central Indiana, with a funnel cloud near the ground in Henry County, before a tornado that started as an EF0 in Hamilton County, which tracked for 3 miles into Madison County, peaking at EF2 intensity just before dissipating.

NWS Indianapolis, IN wrote its last area forecast discussion before the first event at Jul 29, 6:11 PM EST, 1 hour 15 minutes earlier. Its key messages:
Area Forecast Discussion...UPDATED National Weather Service Indianapolis IN 711 PM EDT Mon Jul 29 2024 .KEY MESSAGES... - Thunderstorms, possibly Severe, expected late this afternoon and this evening. - Thunderstorms may produce very heavy rain - Morning fog possible - Dry and Hot on Tuesday - Daily storm chances continue through Friday, severe weather and localized flooding concerns possible each day. - Heat indices near or above 100 degrees possible Tuesday through Thursday afternoons. - Drier conditions with temperatures nearer normal this weekend. && .MESOSCALE UPDATE... Issued at 711 PM EDT Mon Jul 29 2024 Deeper convection is developing 1. at the leading edge of modest EML plume seen on 7.4 micron satellite, now moving into Ohio, and 2. ahead of weak midlevel perturbation seen in water vapor near the Illinois/Indiana border. We will need to watch the cell near Noblesville very closely given sufficient low level shear per model proximity hodographs and sizable near-ground buoyancy with low LCL heights. Weak low level rotation has been noted on radar. This is our near-term concern. Further west, weak echoes appear to be shallow convective process within moist PBL capped by aforementioned EML. There is conditionality for robust convective development and upscale growth further west across Illinois given magnitude of the EML/subsident layer seen in satellite imagery and the absence of noteworthy forcing for ascent to erode this. A more robust uptick in convection may occur later this evening as modest low level jet and associated warm moist advection interact with an east-west surface boundary. && .SHORT TERM (This evening through Tuesday)... Issued at 214 PM EDT Mon Jul 29 2024 Synopsis - Radar this afternoon shows new thunderstorm development along a boundary in east Central IL that was laid out earlier today by prior convection. The earlier MCS complex has continued to decay, pushing southeast of Central Indiana. Cloud cover across Central Indiana has limited heating through early afternoon, but satellite trends suggest subsidence and decreasing cloudiness. The surface analysis early this afternoon shows high pressure in place across the Carolinas and low pressure in place over western Kansas. This was resulting in warmer southwest flow spilling into the Ohio Valley. Aloft, a negatively tilted upper trough was in place from MN to eastern KY, with the trough axis mainly east of Central Indiana. Still, water vapor shows plentiful moisture within the trough over Central Indiana. Dew Points remain very moist in the lower to middle 70s. This Afternoon and Tonight - SPC mesoanalysis pages shows CIN across central Indiana has dissipated and CAPE of 1500-2000 J/KG present. IND ACARS soundings showing plenty of CAPE aloft also, but just a lower level inversion in place at the moment. This is expected to change as the clouds continue to dissipate and lead to heating into the middle 80s. This should trigger convection by late this afternoon and evening. HRRR and several DESI members suggest strong thunderstorm development late this afternoon and evening. A favorable column will remain present along with warm air advection and the cyclonic flow aloft. Thus many elements are in place tonight for continued showers and storm development. Tornadoes cannot be ruled out given the very high dew points that will result in low LCL's. Best area for development will be along and south of I-70, particularly within a IND-HUF-BMG triangle area. Very high pwats will result in efficient rain production. Torrential rains will be possible resulting in Flooding and this will remain a threat. Overnight, models suggest that convection will continue to diminish storms as they exit southeast. Remnant lower level moisture along with clearing skies and light winds will allow for the development of patchy fog overnight. No strong change in air mass is expected, and dew point depressions are expected to fall to 1-2F or less. Thus a least patchy fog will be expected. Look for overnight lows in the upper 60s in rural locations and lower 70s. Tuesday - The very warm and humid air mass is expected to remain in place on Tuesday. Models suggest ridging building aloft as warm air advection continues. 850MB temps are suggested to reach near 24C through the afternoon as a thermal ridge is expected to build across Indiana from the plains. Little in the way of forcing aloft will be present. Forecast soundings suggest a capped column with a mid level inversion in place due to the warm air advection aloft. An isolated afternoon storm cannot be rules out across southwest central Indiana where the cap may be a bit weaker. Small pops might be used here. Thus after morning fog burns off, look for a partly to mostly sunny day along with hot weather. Look for highs in the lower to middle 90s. && .LONG TERM (Tuesday night through Monday)... Issued at 214 PM EDT Mon Jul 29 2024 Much of the long term will remain rather unsettled as central Indiana is positioned down stream on an amplified ridge, with a succession of upper level waves moving over northern portions of the CONUS. Also of not will be the presence of a quasi-stationary boundary that will be the focal point for continued convective initiation each day through Friday. As we enter the weekend, the troughing to our NW looks to become more prominent, pushing central Indiana into a potentially cooler and drier northwest flow for the coming weekend. The mesoscale environment will largely be synonymous with a typical high CAPE/Low Shear pattern, outside of increases to shear in the evening and overnight associated with nocturnal LLJs. Those type of patterns typically lead to robust convection on the periphery of the moisture tongue and along any instability gradient. This general area should be broadly over the Ohio Valley each of Wednesday through Friday, but there is still some uncertainty on the specific locations. Given the high probability of steep low level lapse rates, and high low level moisture, linear complexes are the most likely mode, with high winds and isolated tornadoes possible within any organized structure. Also of concern will be trailing boundaries along the moisture axis leading to training thunderstorms and flooding. This will become an even greater concern late week if these MCCs develop over similar areas. The amplifying pattern late week into the weekend, with central Indiana between the ridge axis well to the west and trough axis to the east, along with southward push of a cooler and drier Canadian high pressure center, will bring temperatures and humidity back down nearer seasonal normals, with highs in the mid to upper 80s and dewpoints back into the 60s. && .AVIATION (00Z TAF Issuance)... Issued at 649 PM EDT Mon Jul 29 2024 Impacts: - Thunderstorms increasing this evening - Some fog with IFR or worse possible late tonight Discussion: Some MVFR stratus is possible in the near term, but is not expected to be consistent. Thunderstorm coverage may be somewhat limited, but probability is high enough for a window of TEMPO thunder this evening. Afterwards, cloud cover is the caveat to fog formation but moist ground and light winds and perhaps some cloud breaks could allow for some fog. Potentially locally dense. Amendments for storm timing and fog magnitude will be needed through the evening and tonight. && .IND WATCHES/WARNINGS/ADVISORIES...

The Indianapolis radar (KIND), 82 km away, was scanning. The volume nearest the first event began at 00:28 UTC.
6 thunderstorm wind, 2 tornado. Local standard time, as filed.
Thunderstorm winds downed several trees in the New Castle area, before a funnel cloud was observed just above the ground 1 mile east of New Castle.
The tornado began as an EF0 with damage to the roof of a metal barn and uprooted trees along Strawtown Road, just west of Indiana State Road 13 in Hamilton County. The tornado skipped over SR 13 into Madison County where it continued for another 2.6 miles while intensifying to an EF2. The tornado's maximum width of 50 yards occurred in Madison County.
The tornado began in far eastern Hamilton County as an EF0 before skipping across Indiana Route 13 into Madison County and quickly landing in a field at a cemetery south of Perkinsville in Madison county, causing sporadic tree damage. The tornado crossed the White River, snapping and uprooting several trees at a residence south of County Road 300 North where it was rated an EF1. The tornado then moved into a corn field before lifting briefly prior to hitting the Frankton Lapel Administration Building where significant brick wall and roof damage occurred. The roof of a small gymnasium at this building was lifted and thrown approximately 150 yards to the north northeast while the western brick wall collapsed inward. Numerous concrete masonry blocks were thrown from the wall into the top of several school buses that also sustained damage. One bus had a small but long metal support driven through the frame. The tornado was rated EF2 here before it continued into a corn field to the northeast and dissipated.
Thunderstorm winds blew trees limbs over 100 feet and lifted a 4.5-ton air-conditioner unit off of its base, tipping it on its side and blowing components 35 feet.
Thunderstorm winds downed several trees in Spencer.
Thunderstorm winds downed several trees on to Pleasant Run.
Thunderstorm winds downed a tree near the intersection of Calvertville Road and Newark Road.
Thunderstorm winds downed several trees across central Lawrence County, from near the intersection of State Roads 158 and 458 to south of Bedford.
