What EF1 means. On the Enhanced Fujita scale, EF1 is moderate damage: roofs badly stripped, mobile homes pushed off foundations or overturned, windows broken, consistent with estimated gusts of 86–110 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 fourth tornado to impact central Indiana on May 21st, an EF1, uprooted and snapped trees as the very small tornadic circulation moved through the Auburn Hills subdivision.

The wider storm

A warm and rather humid air mass across central Indiana, combined with an approaching cold front in the afternoon to produce a line of strong to severe thunderstorms. Wind damage was focused over the region's south-central counties; the line also spawned two brief EF0 tornadoes before a longer track EF1 lifted and touched down several times across southern Shelby County. A forth and final EF1 tornado tracked briefly over far southwestern Shelby County.

Began near Mt Auburn (39.3750, -85.9070).
