What happened

The episode as NWS DMX wrote it up.

A very moist and unstable airmass was in place over the central U.S. Surface dew point temperatures were in the mid 60s to low 70s across the area. A quasi-stationary front was stretched east to west across west central into southeast Iowa. Thunderstorms erupted along and to the north of the boundary. Many of the storms produced hail of pea to marble size, along with very heavy rainfall. One of the cells became severe and dropped large hail in a swath from Crawford County into Dallas County. Hail of golf ball size was reported with this cell in several locations. One report of nearly tennis ball size hail was received from east of Adel. The storm produced a couple of brief tornado touchdowns. The touchdowns were very brief and in open country. As a result, no damage was reported. The tornadoes were wrapped in the rain and were no more than rope tornadoes at best. The storm weakened very rapidly as it encountered the outflow boundary from further convection to its southeast.
