What happened

The episode as NWS DMX wrote it up.

Yet another heavy rain event affected much of central and south central Iowa on the night of the 27th with Guthrie Center reporting 6.73 inches of rain. A few unofficial reports were as high as 7 inches that fell in the Stuart area of southeast Guthrie County. Rainfall in the metro Des Moines area ranged from 2 to as much as 5 inches. Monthly rain totals exceeded a foot over parts of south central Iowa while sections of far western and northern Iowa recorded a drier than normal July. Preliminary monthly rain totals vary from only 1.66 inches at Clarinda and 1.92 inches at Red Oak to 12.50 inches at Allerton and 12.81 inches at Lake Rathbun Dam. Unofficial totals as high as 13.87 inches were reported near Indianola. Statewide this was Iowa’s wettest July since 1993 when the all-time calendar month record of 10.50 inches was set. Year-to-date precipitation totals have already exceeded annual normals over much of south central, central and northeast Iowa. In terms of statewide average precipitation the first seven months of 2008 are the second wettest January through July period among 136 years of records. This year’s preliminary total is 30.18 inches, normal for the period is 20.59 inches and the only wetter period came in 1993 with 32.98 inches. With the wet soil conditions, rivers were again pushed over flood stage in many areas throughout central, south central, and southeast Iowa. Flooding was mainly restricted to agricultural lands, adding to the already large damage totals to the states cash crops.
