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.

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.

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.
