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 NWS survey indicated that an EF-1 tornado touched down near the Polk and Dallas county line near the intersection of Highway EE and South 245th Road. Additional details of the track and damage will be in the Dallas County portion of this report as only tree damage occurred for the Polk County portion of the tornado track.

The wider storm

A strong system moved across the Midwest and brought a round of severe storms to the Ozarks late on the 28th and early on the 29th of February. A squall line with embedded bows and super cellular type storms produced large hail and very strong damaging winds along with several deadly and destructive tornadoes.

Began near Schofield (37.5500, -93.1902).
