(National Weather Service/Des Moines) – The State of Iowa had its test tornado drill Wed., Mar 24th. In case you are wondering how common is it for a Tornado Warning to affect at least part of your county? The Iowa State University/Iowa Environmental Mesonet crunched the numbers from 2006 to 2020 to find out. (See the graphic) For many Iowans, tornadoes are the most frightening weather phenomena and something that many folks actively run practice drills for. The NWS issues a tornado warning when a tornado is observed and/or indicated to be imminent by Doppler RADAR. The featured map presents the average number of tornado warnings per year by county over the past 15 years.
Please note that the official warning presently are polygon geographies, but the counties are still used by some warning dissemination systems. Linn County (Cedar Rapids) shows up with the highest frequency on the map with other urban centers clearly visible as well. There are many complexities as to why such variability exists over the state, but distance from the nearest RADAR is an important aspect as the earth’s curvature causes the RADAR to miss the lowest parts (which are sometimes the rotating ones) as the beam travels further away from the RADAR site.
Today: Partly cloudy to cloudy w/scattered light rain. High 49. NE @ 10-15.
Tonight: P/Cldy. Low 30.

Iowa Homeland Security and Emergency Management and the National Weather Service have declared the week of March 22 through March 26, 2021 Severe Weather Awareness Week. Severe Weather Awareness Week is an annual event to remind Iowans that severe weather is part of being in Iowa and that understanding the risks and how to respond to them can save lives. The highlight of the week will be a statewide tornado drill on Wednesday, March 24th.
For this drill, the National Weather Service in Des Moines will issue a mock tornado warning issued at approximately 11:00AM coinciding with weekly weather radio testing. Outdoor warning sirens will be sounded at or soon after 11:00AM in cities throughout Cass County, according to Mike Kennon, Cass County Emergency Management Coordinator. Also, those who subscribe to the Cass County Emergency Notification System will receive an alert concerning the drill. Kennon adds,”This is an excellent opportunity for residents, businesses, and schools to practice their own procedures in the event of a real severe weather event.”
In the event of actual severe weather occurring during or close to the drill time, the drill will be cancelled. To register for the Cass County Emergency Notification System, go to links located on the Cass County homepage or the Cass County EMA Facebook page. If you need assistance, contact Mike Kennon, Cass County Emergency Management Agency Coordinator at 712-243-1500.
