What happened

The episode as NWS DMX wrote it up.

Intense low pressure that was over northern Minnesota the previous day had moved into southwest Ontario, north of Lake Superior, during the day on the 27th. A lobe of low pressure rotated around the low as strong cold air advection took place over Iowa. Winds increased sharply after sunrise with wind gusts in excess of 58 MPH over a large part of central and north central Iowa. The strongest winds were recorded in central Iowa in Boone, Story, into Polk County. Winds gusted to 63 MPH in Boone, with 62 MPH winds in the Des Moines metropolitan area. The high winds overturned three semi tractor-trailer trucks, one in Boone County, one on Interstate 35 in Franklin County near Dows, and the other in Story County. All three drivers received minor injuries from the accidents. Scattered power outages were reported around the state. Outages peaked around 1000 customers during the afternoon hours. Minor tree damage was also reported around the state.
