Nebraska residents shared their photos on Twitter and Facebook to show the extent of damage brought by the large hailstones. In Omaha, a police sergeant shared an image of a car that was dented by the hailstones.

Other residents showed pictures of shattered windows of their vehicles and homes, due to the strong hail. Residents from low areas were evacuated in order to keep them safe from flooding and the threat of the storm.

Observation program leader for the National Weather Service in Nebraska Terry Landsvork said, “The storms, we call it training. It’s like a train going down the track. One car goes by, another one follows. That’s what’s happening.” He explained that the thunderstorms were moving over the same areas, referring to western Iowa and Nebraska.

In Iowa, Gov. Terry Branstad declared a storm disaster proclamation for Pottawattamie County on Tuesday night, as the storms landed while voters were on their way to the polls for the primary elections.
