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

This tenth tornado to impact central Indiana was the last of five tornadoes spawned within Madison County and Delaware County, and the last of three secondary tornadoes to track within these two counties, tracking to the south of the main tornado. The tornado tracked between the Anthony area and the Delaware County Airport, approaching the Shideier community before ending. Sporadic damage along the track indicates the circulation was not continually on the ground as the tornado was likely embedded within the parent storm's rear flank downdraft. The tornado was strongest at its onset where it destroyed a barn by collapsing its walls, and at the track's end where it completely destroyed a farm outbuilding. Peak wind gusts were 100 mph.

The wider storm

A strong low pressure system generated a line of strong to severe thunderstorms that started in Illinois and moved across central Indiana. Multiple severe storms were embedded within the line and some of these produced tornadoes. Eleven tornadoes impacted central Indiana, ten of which occurred along an overall west-southwest to east-northeast area from north of Terre Haute to north of Muncie. Four of these events, from Hendricks County to Delaware County, were secondary tornadoes that tracked parallel to longer duration tornadoes. Three tornadoes combined to impact western and northern portions of the Indianapolis Metro area, including an EF2 in Hendricks County that caused the episode's only injury. In addition to the tornadoes widespread wind damage occurred with gusts over 80+ mph reported.

Began near Devon Park (40.2488, -85.4646).
