6. EF5over 200 mph

   Incredible damage. Strong frame houses swept off their foundations, car-sized missiles thrown more than 100 meters, steel-reinforced concrete badly damaged, high-rise buildings deformed.

7. Unrated

   The survey recorded a tornado but could not put a number on it, most often because it crossed open country and damaged nothing a rating can be read from.

The tornado touched down west of Campbell road and impacted several farm buildings along Campbell road. One of the farm buildings was completely destroyed with debris scattered into an open field to the east. The tornado then mostly traveled over farm fields in eastern Johnson county before impacting two homes along Rocklane Road. Debris from a damaged outbuilding near the first home on Rocklane Road was picked up and thrown about 650 yards to the northeast. The tornado continued into Shelby county where it impacted one home along West 525 North before traveling through open fields and impacting one additional home on 600W. The tornado then tracked mostly through open fields, impacting a home south of Clover Village before it crossed Interstate 74 and passed harmlessly through several additional fields. There was another concentrated area of damage near 75W and 600N where widespread tree damage and minor home damage was noted. It then dissipated in an open field near Hill Branch Creek. The tornado may have lifted briefly along the path.

Written by NWS IND in the NWS Damage Assessment Toolkit. A survey is revised as better evidence arrives.

39 damage points were recorded along this path by NWS IND, in the Damage Assessment Toolkit the survey teams carry. The strongest indicator was rated EF1. The highest wind the damage implies is 105 mph.

• Trusses were turned 90 degrees and north side of outbuilding pushed over to the south. Debris scattered in the field.
• Door on the south side was blown inward. Part of roof peeled and facing east. East side door was blown out but likely because winds funneled through broken part of the roof. Some mud splattering but only on south side of building
• Convergent pattern noticeable with a few trees facing more SE while the other trees face E or NE. Roof of outbuilding from neighbors house about 650 yards to the southwest landed in the yard. Look like tornado dissipated in the field to the NE.
• A lot of large tree branches facing ENE or NE. Some branches thrown back towards the southwest. Trees somewhat suggest a convergent pattern

During the 11th evening, a cold front interacted with a warm, moist, and unstable air mass across central and northern Indiana, initiating a fast-moving severe convective line. The synoptic setup supported widespread straight-line wind damage and embedded mesovortices as the squall line tracked eastward through the region between 7:59 PM EST and 10:32 PM EST.||Five tornadoes touched down across Warren, Carroll, Johnson, Shelby, and Randolph counties during the event. Four brief EF-0 tornadoes produced peak winds between 70 mph and 85 mph, causing tree damage and minor agricultural impacts. The most significant tornado was an EF-1 that tracked nearly 12 miles across Johnson and Shelby counties, generating peak winds of 105 mph that damaged several homes, outbuildings, and trees.||Widespread straight-line winds produced the majority of the severe impacts as the line moved across more than a dozen counties. Measured wind gusts frequently ranged from 59 mph to 67 mph, with localized straight-line winds estimated up to 95 mph in Howard County. Damage across the region included widespread downed trees and power lines, overturned commercial vehicles on major highways, and structural damage to roofs, barns, and outbuildings. This severe weather event would be the third of many for the month which would eventually define a formal disaster period from June 6th to the 18th which was declared by the governor of Indiana.

An EF-1 tornado with path length of 11.94 miles and a path width of 200 yards began in Johnson county with 2.47 miles of it within Johnson county. The tornado had a peak wind of 105 mph with peak winds of 90 mph within Johnson county. Within Johnson county, impacts were limited to tree damage and several farms and structures with minor damage.

An EF-1 tornado with path length of 11.94 miles and a path width of 200 yards began in Johnson county and continued into Shelby county with 9.47 miles of it within Shelby county. The tornado had a peak wind of 105 mph with peak winds. Within Shelby county, the most intense damage happened along homes near 600W and 75W with several homes impacted along with widespread tree damage.

13 minutes of warning. NWS IND issued a tornado warning for this county at 02:50 UTC, 13 minutes before the tornado touched down, in force until 03:15 UTC.

The county was under a severe thunderstorm watch, issued at 01:49 UTC and running to 05:09 UTC.

Every warning and watch covering the touchdown point that day, from the Iowa Environmental Mesonet's archive of National Weather Service products. Lead time is measured from the issue of the warning in force to the touchdown time in the database, both of which were recorded to the minute by different people.

The Storm Prediction Center had this point in a Slight Risk, with a 0.02 chance of a tornado within 25 miles. The outlook in force was issued at 01:00 UTC.

Ratings are the survey's, read off the damage rather than measured; the rating scale is above. A survey can be revised, so the rating, the path and the casualties can all still change.

NWS Damage Assessment Toolkit, the record the survey teams file from the damage, and NOAA Storm Prediction Center storm reports. Neither is the official database for 2026, which SPC publishes in the spring of 2027.
