Thunderstorms developed ahead of an area of low pressure and a cold front during the late evening of June 5th and the early morning of June 6th. These storms brought multiple tornadoes to northern sections of Indiana, including two in Carroll County. These two tornadoes originated from the same thunderstorm. One tornado was reported near Yeoman in western Carroll County and the other was reported in eastern Carroll County.

A supercell developed ahead of a cold front in Illinois and tracked east-southeast through Benton county into White county. This storm produced three tornadoes across Indiana, an EF0 in Eastern White County (which moved into Carroll County), an EF1 which started in eastern Carroll County and moved into Cass County, and a third, a stronger EF3 which formed near the Grissom Air Force base in Cass County and moved rapidly east into Miami County. Despite the tornadoes occurring during the overnight hours, no fatalities occurred.

A trained spotter reported a tornado silhouetted by lightning in this location. This tornado touched down near County Road 700 N and 500 E in eastern Carroll County around 1:25 AM EDT. Two hog barns were destroyed in the path of this tornado before continuing on into Cass County. Based on the damage observed, this appeared to be a high EF1 tornado with winds approaching 110 mph.

This tornado developed in eastern Carroll County, Indiana, roughly four miles east-southeast of Burrows (see Storm Data for Indiana, Central) and moved into Cass County. The tornado initially was over open fields with its first impact at a residence where the western half of the roof was ripped off and the eastern half picked up and then dropped back down. Two residents were attempting to take shelter when the tornado hit. A gentleman suffered minor injuries (indirect) falling down a stairway into a basement seeking shelter. The tornado continued east-southeast over mainly open field again until it encountered a more populated area of structures along E County Road 900 S, east of S County Road 300 E. Several trees were damaged or uprooted in the area with the western half of a business being destroyed by the circulation. The circulation moved on to strike and roll a mobile home, destroying it (DI: SWMH DOD: 7). The second injury (direct) in the area occurred here where the resident was rolled with the mobile home. The female resident escaped with minor injuries. The circulation continued on causing some structure and tree damage before dissipating. The maximum width is estimated at 150 yards with a maximum wind speed estimated around 100 mph.

After a brief break, the supercell produced one more circulation which touched down just west of the Cass/Miami county line along South County Road 1000 East. Several yards in the area had trees uprooted and limbs down (DI: TH, DOD: 4). A few residences were impacted by the trees, causing mainly roof or window damage. The circulation then went into a dense grove of trees with the circulation briefly weakening before coming back out near the Grissom Air Reserve Base. A 200 foot section of security fence on the southwest corner of the base was blown down into the adjacent roadway and portions of the nearby field before crossing into Miami County. An Automated Weather Observation System recorded a 114 mph wind gust as the circulation passed through.

4 minutes of warning. NWS IND issued a tornado warning for this county at 05:21 UTC, 4 minutes before the tornado touched down, in force until 05:36 UTC.

The county was under a tornado watch, issued at 02:13 UTC and running to 07:23 UTC.

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 Moderate Risk, with a 0.10 chance of a tornado within 25 miles, in the hatched area where significant tornadoes were expected. The outlook in force was issued at 01:06 UTC.

42 more were confirmed in the United States that day.

Ratings are the survey's, read off the damage rather than measured; the rating scale is above. Tornado counts rise through the record as reporting improved, so a year in the 1950s is not comparable with one today except for the strongest tornadoes, which were always noticed.
