What happened

The episode as NWS DMX wrote it up.

An unstable airmass was in place over Iowa with CAPE over 2000 J/kg already by early in the morning. Downdraft CAPE was quite high, in the 1000 to 1300 J/kg range, with 400 to 600 J/kg in the -10 to -30 C layer of the atmosphere. The shear was quite weak, in the 25 to 35 kt range. Deep moisture was in place with precipitable water values of 1.8 inches. The LCL was quite low as well, in the 500 to 750 meter range. There was little hail as the freezing level was quite high at 14,400 feet. Strong thunderstorms developed in a north to south line across eastern Nebraska and western Iowa. During the morning the line took on a bow echo appearance as bow beta elements began to push rapidly east. A swath of 60 to 70 MPH winds took place from east of the Omaha-Council Bulffs area in southwest Iowa all the way east into central Iowa in the Marshalltown and Oskaloosa areas. The high winds overturned semi-tractortrailer trucks in Guthrie and Greene Counties. Shingles were also blown from a house in Guthrie Count west of Guthrie Center. In Audubon County, high winds lifted two farm buildings off of their post foundations and carried them one quarter of a mile away. A funnel cloud was observed west of Eldora in Hardin County. Very heavy rainfall occurred over parts of northeast Iowa. Franklin, Butler, and Grundy Counties were hard hit. Numerous roads and highways were under water and closed as 4 to over 7 inches of rain fell in under six hours. The heaviest rainfall total was in the Aplington Area in Butler County. A total of 7.5 inches fell there. Severe flooding took place in the New Hartford area. Near record high river stages prompted the evacuation of the town. In Parkersburg, 1500 to 2000 feet of railroad tracks were washed out. There was some hail with the storms. Most of them had small hail, though no significant hail was reported.
