The Storm Prediction Center in Norman, Oklahoma has posted a moderate risk of severe weather across western Iowa. Tornadoes, very large hail, an organized damaging wind threat, and flash flooding is all possible later tonight with this system.

A system across northwest Iowa and Minnesota is currently producing some elevated storms with a large hail threat. This is expected to move out of the area and leave a boundary where it currently is. The atmosphere will heat up this afternoon and increase instability. In combination with dew points in the 50s and 60s and wind shear of 40-50 knots, storms will likely become organized and supercellular as they develop in the mid-afternoon. The primary threats early will be very large hail, some tornadoes (possibly significant), and an isolated damaging wind threat. Later in the evening, the threats are expected to change to a organized damaging winds to 80 MPH and flash flooding. This should move out of the area by the overnight hours.
