What happened

The episode as NWS DVN wrote it up.

A strong arctic front extended from Central Wisconsin into Northwest Missouri early Friday morning. Temperatures across the state of Iowa at 6 A.M. Friday ranged from the middle 20s in the far northwest to the middle and upper 50s in the far southeast. Much colder air was poised to the north of the state with temperatures in the single digits and teens in the Northern Plains. This arctic front and the large temperature gradient across it combined with a vigorous upper level disturbance ejecting from the Southwestern United States to ignite severe thunderstorms. Initial development occurred in Central Iowa late Friday afternoon and evening. These storms then evolved into a squall line, which raced eastward through much of Eastern Iowa during the overnight and early morning on Saturday, producing numerous reports of wind damage. The most significant damage was concentrated in two areas, one from Johnson County into portions of Jones and Cedar Counties, and the other in Southeast Iowa generally along and south of Highway 34. Winds were generally in the 60 mph to 80 mph range. With the frontal passage, temperatures plummeted some 20 degrees over a period of a few hours, causing any lingering rain to briefly change over to sleet or a mixture of sleet, snow and freezing rain mainly north of Interstate 80.

A property suffered heavy damage. A large sliding door to a metal building was blown down and destroyed, a fence was damaged, a semi-trailer was tipped over and moved, the tin roof on an old shed was torn off, and an empty grain elevator was tipped over and moved. Additionally, many water tanks and other supplies that were piled around had been jumbled and thrown around. The owner credited some rail cars parked along the west side of the property with limiting the damage by providing a break from the wind. Also, a pole building on an adjacent lot northeast of the property was upended and destroyed with tractors and other equipment inside. The equipment suffered damage but was still driveable. Across the street from the pole building, a residence lost a chimney. Just east of that residence, was another residence which suffered the most damage seen in town. The home had damage on all four sides with windows broken out, siding damaged, a chimney destroyed, shingles removed and roof damage. A child was asleep in a first floor bedroom when the home was damaged. The mother reported that it was very difficult opening the door to the bedroom because of the force of the wind. The child was in bed with broken glass throughout the room and in the bed, but luckily there were no injuries. There was mud and debris plastered on the walls and in the room. Also, there was an old truck parked on a street on the east side of the home that was pushed into another vehicle parked nearby. Power lines were down, and the home was without power until 4:30 pm Saturday. Across the street from this residence was another home which suffered some roof damage, damage to a chimney and a playhouse which was tipped over and moved. There were also trees down throughout town.
