Chad Hahn, warning coordination meteorologist at the National Weather Service, also confirmed a tornado did not touch down in Newton or Jasper County. He said there was a strong rotating wall cloud on the storm, which along with the rotation identified on radar prompted the tornado warning.

Heavy rain caused flooding issues in Ames and rotation was observed in clouds around the Iowa Speedway in Newton as the area was under a tornado warning. All watches and warnings have expired for central Iowa, but major flooding continues in some eastern Iowa communities after heavy rain and possible tornadoes.
