Hail ranging in size from nickels to quarters pelted and pounded parts of Audubon County late Saturday night. Just before 11-p.m., one-inch diameter hail was reported to the National Weather Service by law enforcement in Audubon. About 30-minutes later, severe storm spotters reported nickel-to pea-sized hail was falling 10 miles northwest of the Audubon Airport. There were no immediate reports of damage early this (Sunday) morning.

A severe thunderstorm warning was issued late last night for northern Audubon County, southern Carroll County and northwestern Guthrie County, for the storm system as it passed through the area.

The storm also dumped heavy rain in parts of Iowa. Parts of Jasper, Marshall and Poweshiek Counties in east central Iowa received four-to six-inches of rain overnight, causing some roads to be flooded. The Weather Service said a total of six-to eight-inches of rain was possible in eastern Iowa through early this morning. A Flood Warning was in effect for Jasper, Marshall and Poweeshiek counties this morning.

At around 5:30-a.m., storm spotters reported sand bagging efforts were underway to protect the Kellogg water treatment plant and fire department. 4-a.m., law enforcement officials in Jasper County reported water was covering the road at Illinois Avenue and Highway 6, near Kellogg. Parts of Northfield Drive were under water, with one house surrounding by water. Law enforcement reported also that flooding was occurring in the Oakland Acres area of Jasper County, with Highway 6 under water, and closed with stalled cars.

For the KJAN listening area, a Flash Flood Watch remains in effect until 9-a.m. The Watch includes Audubon, Guthrie, Crawford, Carroll, Sac and Dallas Counties.
