[Updated] (Logan, Iowa) – A storm spotter/first responder was injured and several properties were damaged when severe storms swept through Harrison County, Tuesday. Harrison County Emergency Management coordinator Philip Davis said in a news release, that he found “significant damages” to two residences south of Logan while out assessing the storm damage on Wednesday. He also found “major damage” to a home in the Woodbine area. Trees and agricultural lands also sustained some damage.
Davis said also, a responder who was helping with storm spotting during the storm was injured. The extent of that person’s injuries has not yet been released. The National Weather Service issued a warning for Harrison County around 7:53 p.m. Tuesday. It warned of a line of severe thunderstorms capable of producing a tornado. The NWS has not yet confirmed a tornado touched down in that area. On Thursday, the NWS did say eight confirmed tornadoes took place elsewhere across the State, Tuesday.
The strongest twisters were rated at EF2 outside Gilmore City, in Pocahontas County, and in Humboldt County, near Bradgate. In the northeast part of the state, an EF1 hit southwest of Mason City, and an EF0 was briefly on the ground in Hancock County. Three weaker tornadoes were reported in Mitchell and Howard counties. All but one of the twisters were packing winds in excess of 100-mph.
Harrison County officials want to know if anyone else in the county has damaged property as a result of the storm. Anyone with damage was asked to report it by clicking here or calling Harrison County Communications at 712-644-2244.

(Radio Iowa) – A storm front pushed hazardous weather through the state Tuesday afternoon and evening, spawning hail and damaging winds in some areas. National Weather Service meteorologist Rod Donovan says northern Iowa took the brunt of it. “We did have a couple of tornado confirmations certainly around the Gilmore City area in addition to near Bode and Harvey up in Humboldt County as well, so we will be sending storm survey crews up there today to really determine the damage,” Donovan says. “We have actually had some other potential areas that we could have some minor or isolated tornado touchdowns as well.”
Hail that was a bit larger than two-and-a-half inches in diameter was reported near Gilmore City. There were no reports anyone was injured in Tuesday’s storm. Cool and windy conditions remain in the forecast for the next few days. “Really, overall kind of an unpleasant day Thursday where we’ll have wind gusts in that 40-50 mile range through most of the day,” Donovan says.

Tuesday’s High in Atlantic of 85 was just 1 degree shy of tying the record set in 1916. We received .46″ rain Tue. night, along with pea size hail. Our Low this morning, 38.

(Radio Iowa) – The University of Iowa has been selected to be a partner in a 360 million dollar national consortium to work on improving flood predictions. The U-I’s Larry Weber will lead the effort in Iowa and says they will build on what they have done here to combat flooding. “The Iowa flood information system that we’ve created for the state of Iowa, has been recognized by people across the country as the best in class and information for flooding. And we’ll be expanding that I will flood information system to the Upper Mississippi River Basin and the Mississippi River basin, and then eventually the entire nation,” Weber says.
Weber leads the university’s Hydroscience and Engineering program and says they have deployed sensors across the state while also developing new sensor technology to help in the monitoring of the onset of flooding. This technology will not get broader use. “Sharing that technology with other partners that then could deploy similar technology in their own states,” he says. He says they will also work on other areas of flooding. “A second area that will have a lot of work is going to be in creating new technologies for fast and reliable floodplain mapping. So providing those recurrence level maps for the 100-year flood, and that 500-year flood and floods in between,” Weber says.
Weber says water quality is something that’s included in the project along with the flood monitoring and floodplain maps. “The Weather Service is quite interested in working with their federal partners, to begin to create a real-time water quality forecast model for rivers and streams in the nation,” according to Weber. “And given the strength of our work here in Iowa and that area, we think that will contribute to that strongly as well.” Weber says there are different types of flooding across the country that they will be dealing with. “In our steeper mountainous streams, we get more flash flooding. So we may get rainfall that produces a flood, you know, that that that comes up in a matter of minutes or hours. That’s really quite different. Along a coastline, we get compound flooding, where we have storm surge from the ocean or from the Gulf, that provides a bottleneck to the rivers that are flowing to the ocean to the Gulf,” he says.
That bottleneck can lead to flooding. The five-year program will be headquartered at the University of Alabama. It is funded for five years by the National Oceanic and Atmospheric Administration and Iowa will receive 21 million dollars for its portion of the work.
