What EF3 means. On the Enhanced Fujita scale, EF3 is severe damage: whole stories of well-built houses destroyed, large buildings badly damaged, trains overturned, consistent with estimated gusts of 136–165 mph. The rating comes from a survey of the worst damage after the storm, not from a wind measurement, so it says as much about what the tornado hit as about how strong it was.

What the National Weather Service wrote

The tornado that entered this county exited the Grissom Air Reserve base on the Cass/Miami county line and continued east-southeast, crossing a small area of trees where signs of slight debarking was noted (DI: TH DOD: 5). The tornado continued on along to the 3000 block of County Road 900 South where the most substantial damage occurred to a one and one half story home. Only a few kitchen walls remains of the structure (DI: FR12, DOD 8) with one resident in the kitchen and one in the basement. Two other residences suffered extensive damage but remained intact. The tornado crossed US 31 and continued for a few more miles, causing some additional tree and structure damage including several buildings at a hog farm being destroyed. The tornado eventually dissipated east of Strawpike Road, north of East 1000 South in a field. A local newspaper article reported that a check that was originally located at the destroyed home was found nearly 50 miles away in Wells County in perfect condition. Total damage along the track of the tornado is estimated at $750,000.

The wider storm

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.

Began near (gus)grissom Afb Per (40.6382, -86.1656).
