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 in a farm field north of Highway O and west of Oak Avenue, which is west-northwest of Maywood. The tornado moved east northeast directly hitting a home in its path, causing EF-1 damage by lifting a large portion of the roof from the residence. Roofing materials were found up to a half mile to the east. The tornado continued east northeast toward Oak Avenue causing significant tree damage. At Oak Avenue the tornado rolled a full size tanker truck on its side and destroyed two grain bins. The tornado continued east northeast across Olive Avenue causing additional tree damage. The tornado dissipated a few hundred yards to the east of Olive Avenue in another farm field. The tornado was rated EF-1 with a path length of 2.01 miles and a max path width of 150 yards.
