“We generally look at buildings and structures, and then determine the wind speed and from that we can determine the rating of any tornado that may have occurred,” said National Weather Service Meteorologist Roger Vachalek.
The tornado overturned a camper, downed power lines and tree limbs in Halbur, Iowa, and ripped the roof and doors off a machine shed further to the northeast in Carroll, Iowa around 8:00 p.m.
The storms began Wednesday in Kansas, Missouri, and Nebraska and were their strongest in western Iowa. Many large hail reports ranging from 1 to 2 inches in diameter were reported from Nebraska, Kansas and Missouri.
Strong winds in excess of 60-mph were also an issue Wednesday evening. In Boone, Iowa, gusts up to 60 miles an hour downed small tree limbs and pelleted the area with nickel sized hail. Winds also toppled power lines onto Highway 69 near Jewell, Iowa.
In Butler County, in northern Iowa, at least eight trees were reported down and a roof was partially torn off a building.
