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

At 8:29 PM a tornado began near the community of Elmont, MO, producing EF1 damage primarily to trees and one large barn. The tornado moved quickly to the northeast, and produced additional tree damage along Missouri route 185, and along Ridge Road within the Long Ridge Conservation Area. The tornado then continued northeast before ending very near Highway 47. Near the end of its path, the tornado damaged several homes, outbuildings, telephone poles and trees within the southern outskirts of Union, MO. The most significant of this damage occurred near N Bend Road, where damage to a home and barn suggested maximum wind speeds of approximately 105 miles per hour.
