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

Another tornado formed about a mile north of the one that had touched down near the intersection of U.S. 67 and State Highway N. It paralled the path of the other tornado lifting and dissipating about half a mile northeast of Madison County Road 303, about three quarters of a mile southeast of the intersection of U.S. 67 and Madison County Road 303. The damage was limited to numerous large trees blown down or uprooted along its path. The widest part of the damage path, about a third of a mile, was where the tornado crossed Madison County Road 303.
