What happened

The episode as NWS DMX wrote it up.

The airmass remained very unstable over Iowa into the afternoon hours. Thunderstorms erupted over northeast Iowa and became severe quickly. The result was large hail. Three inch diameter hail fell on Butler County at Shell Rock, with golf ball size hail in Parkersburg. Damage was reported to cars with broken windows and dents. Some windows were knocked out of a few houses as well. Needless to say, crops were damaged as well.
