Severe weather hit western Iowa on this date 8-years ago

May 10th, 2023 by Ric Hanson

(NWS/Des Moines) – The National Weather Service reminds us severe weather was active on this day (May 10) back in 2015. Storms formed in the evening hours out ahead of a cold front associated with an area of low pressure across South Dakota. The front was stretching South/Southeast across western Iowa by early evening. As one storm lifted northeastward and interacted with a warm front, it produced two tornadoes.
The first tornado of EF-1 intensity touched down in northern Carroll County about 3 miles northwest of Lidderdale and moved northeast impacting Lake City and the western edge of Rockwell City before lifting just north of town. An additional brief touchdown occurred 2 miles west-southwest of Manson, but no damage was found.
A few other storms became severe across western and central Iowa with an 80 mph wind gust reported at the Carroll Airport and some wind damage reported with this storm near Lidderdale. This storm moved north and produced baseball size hail near Lake City shortly after the tornadic storm had moved through the town.
A machine shed was destroyed by straight-line winds in northern Audubon County and also power lines and poles were downed just south of Van Meter in Dallas County. More information on that day can be found here – https://www.weather.gov/…/2015-05-10_LakeCityTornado.pdf
