The Severe Storms Prediction Center in Norman, Oklahoma says another round of severe storms are possible across a large section of Iowa, this afternoon and this evening. The Primary threats include isolated, fast-moving, weak tornadoes, damaging winds, large hail, and periods of heavy rainfall.
Storms will develop this afternoon and will continue through the early evening. The greatest potential for severe weather will be during the peak heating evening commute hours from 3 pm – 7 pm. Storms should be out of our area around midnight.
Most of Iowa is under an “Enhanced Risk” for severe weather. Locations south of I-80, and east of I-35 may see a slightly great threat for severe weather. Strong to severe storms that do develop will likely be very-fast moving, moving to the N/NE at potential speeds of 50 to 60 mph.

Severe storms that began to brew in eastern Nebraska blew into western Iowa Tuesday evening, quickly turning the skies dark. The storms brought winds of up to 70-miles per hour to parts of Carroll and Shelby Counties, and golf ball sized hail in the Crawford County town of Manilla.

About 5-minutes later, a 60-mile per hour gust of wind was recorded at the automated weather station located at the Harlan Airport. Earlier, several large tree branches fell in Missouri Valley and in Council Bluffs, causing power lines to fall in some locations.
The Crawford County Emergency Manager reported golf ball-size hail fell in Manilla, at around 7:45-p.m., and about three-miles east/southeast of Buck Grove, in Crawford County, winds reached up to 70-miles per hour.
