What EF0 means. On the Enhanced Fujita scale, EF0 is light damage: shingles and siding peeled, gutters torn, branches broken, consistent with estimated gusts of 65–85 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 non-supercell, or landspout tornado touched down in a field about 2 miles north of Ely in Linn County Iowa Tuesday evening. The tornado caused crop damage and moved very slowly to the southeast. The tornado then snapped large tree limbs along Ivanhoe Road, and damaged a power pole cross member. The tornado also lifted some loose asphalt and tossed it a short distance away. The tornado then moved through a grove of trees before lifting in a field. The tornado was rated EF0, with maximum winds estimated around 85 mph. The path width was estimated around 50 yards and the tornado was on the ground for 10 to 15 minutes.

The wider storm

Numerous slow-moving storms occurred on the afternoon of June 25, lasting into the evening. These storms quickly became strong to severe, with multiple becoming supercells, which ended up producing locally heavy rainfall, damaging winds, large hail, and four tornadoes that were generally weak, but still capable of damage. Winds were generally 60 mph or greater with the stronger storms, with a corridor of winds greater than 65 mph. These thunderstorms remained nearly stationary in areas, resulting in nearly 2 to 4 inches of quick rainfall and flash flooding.

Began near Ely (41.9100, -91.5760).
