What happened
The episode as NWS DMX wrote it up.
A strong west to northwest flow was in place over the central U.S. Embedded in the flow was a series of weak troughs of low pressure. One of them moved through Iowa on the evening of the 22nd. During the late afternoon and early evening hours, thunderstorms erupted along the surface trough during the period of maximum instability. The storms were moving at over 50 MPH through an environment with an inverted V sounding. The main product was wind. A semi-tractortrailer truck was overturned in Interstate 35 north of Story City in Story County by winds estimated at 75 MPH. Wind damage was also reported around the area. A short time later, a storm produced high winds, causing damage, in Hardin County at Radcliffe. The same parent storm dropped a tornado briefly southwest of Owasa. The tornado was very small and did not produce any damage since it was in open country. As the storms headed east they continued to produce high winds. Wind caused damage in Poweshiek County at Brooklyn. Shortly after this event the storms weakened.
