Damage was consistent with wind speeds of 85-95 miles per hour, which indicates an EF1 tornado. Wentzville, Missouri police Major Paul West says several businesses were damaged.

Winds could gust as high as 50 miles per hour in North Iowa, forecasters say. According to the release damage was also found on a farmstead south of Udell where several outbuildings were damaged and a camper was tipped on its side.

The 300-yard-wide tornado was on the ground for about seven minutes and caused the most significant damage to a home on South Commerce Road. The main threats are damaging winds, large hail and isolated tornadoes.
