Event narrative

This tornado began northwest of the intersection of Raccoon Road and 150th street. The tornado almost immediately impacted a large implement shed and an older wooden barn. The shed was completely destroyed and thrown northeast across 150th street into an adjacent farm field. The barn collapsed downward and shifted to the southeast. The tornado continued northeast through mostly empty cropland and rolling terrain. Some damage was done toward the end of the path near the intersection of Timber Road and 165th street with downed trees and minor outbuilding damage.

Wider weather episode

An embedded shortwave passed across Iowa in the afternoon, providing a focus for convection as it phased with an increasing southerly moisture stream. Steep lapse rates, plenty of instability, and hodographs supporting rotating updrafts all came together to create an environment supportive of hail producing supercells. Storms remained somewhat discrete and produced swaths of hail across central and southern Iowa. The largest hail reported was up to baseball sized in Appanoose County. A tornado also occurred in Wayne County east of Millerton with the storms.
