The storms moved into the northwest part of the state and produced hail, high winds, and funnel clouds. Winds gusted to 63 mph at the Sioux City Gateway Airport. A short time later three-quarter inch diameter hail pelted the area. High winds caused damage in Plymouth County around LeMars. Numerous trees and power lines were downed. Part of a building was destroyed south of LeMars. The local utility company recorded a wind gust of 75 mph. A funnel cloud was sighted a short time earlier west of town.
