Total August precipitation for many of the Kansas stations is available now, and has shown some interesting patterns.
Overall the state was wet. Normal statewide August average precipitation is 3.28 inches. However, this year the statewide average is 4.71 inches, or 144 percent of normal. Naturally, some parts of the state didn’t have as much beneficial rainfall, particularly in the Northwestern Division. However, there were three areas of the state that were extremely wet: the Scandia area in Republic County, Sedgwick County, and the Olathe area. Below are maps showing the August precipitation and departures from normal:
These heavy totals contributed to flooding problems in these areas. Flooding, however, is affected not only but the totals but by the intensity. Below are some of the highest rainfall rates, based on 5-minute data from the KSRE Mesonet stations:

Looking at it slightly differently, you can see those highest intensity rates didn’t all match with the stations with the highest rainfall totals:
