(Atlantic) A severe thunderstorm moved through the area early yesterday morning. Although there were no reported injuries, widespread damages were evident. Winds over 70 mph knocked down trees, large limbs and created property damage with power outages. Strong winds also laid down field corn.
While performing Damage Assessments, Cass County Emergency Management Coordinator, Mike Kennon, noticed some damages were more severe, very concentrated, and seemed to run in a line. A drone was deployed, and he found that his suspicions were correct. A clear path of damage runs along 4th Street in Marne to a cattle feeding operation at 580th and Eastland Road and ends southeast of the intersection of Eastland Road and 590th. This line is nearly 3 miles long. Similar damage was also noticed in the City of Cumberland and a couple of other rural locations in Cass County.
Kennon was interested in what the National Weather Service thought of this, so he submitted pictures and the drone video footage for their evaluation. Rod Donovan of the NWS-Des Moines said, “There may have been some spin-up circulations along the storm’s leading edge. Likely the radar beam started overshooting these features, which were quite shallow.”
The National Weather Service does not plan to conduct a preliminary storm survey.
