Overview

A line of strong and severe thunderstorms went through the eastern portions of north central Nebraska last evening. These storms were along the southwest flank of a larger line that originally evolved from north central South Dakota that moved southeast into north central and northeast Nebraska. The severe storms produced one confirmed tornado, damaging wind gusts, and half dollar sized hail.

Damage was also reported in northern Holt county associated with a microburst. Damage included an empty grain bin that was destroyed, an uprooted tree, and a stock trailer that was tipped over. In addition, two pivots were overturned.
