Event narrative

Report of damage from emergency manager later identified as a tornado path using high resolution satellite imagery. The tornado impacted a outbuilding and tossed debris northward into an agricultural field with EF0 damage.

Wider weather episode

Showers and thunderstorms percolated through much of the day along a stationary boundary over northwest Iowa. By evening a more robust shortwave moved across the area, accompanied by 30 kts of shear and 1500-2000 J/kg of MLCAPE. This allowed for storms to strengthen across west central Iowa with gusty winds producing some minor damage to trees and out buildings. Additionally, due to the orientation of the shear, a few weak tornadoes developed and were discovered using high resolution satellite imagery.
