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

A tornado touched down just southwest of the intersection of U.S. 67 and State Highway N. As it travelled to the northeast and crossed U.S. 67 it blew down or uprooted numerous trees. The damage path width in this area was about 100 yards wide. The tornado continued to the northeast knocking down a lot of trees. As it crossed Madison County Road 303, about a mile southeast of the intersection with U.S. 67, the width of the tornado damage to the trees in this area was about a quarter of a mile wide. The tornado continued to the northeast for about a mile before lifting and dissipating.
