...Heavy Rainfall August 19/20th...

Several rounds of thunderstorms brought heavy rainfall in excess of three inches to portions of southeast Kansas and southern Missouri overnight on the 19th and early on the 20th.   Below is an image of radar estimated rainfall totals from the Flash Flood Monitoring and Prediction (FFMP) program for the previous 12 hours ending at just after 5 AM CDT 08/20/09. Notice the large swath of rainfall in exxcess of three inches from central Stone County to Jasper County and into southeast Kansas over Cherokee and Crawford Counties.

FFMP allowed us to see rainfall rate trends along with accumulations and how they compare to Flash Flood Guidance (FFG) which is an estimate of the amount of rain it takes for an area to flood. The tributary in Barry County shown below indicates rainfall accumulations just over 4 inches through a 7-hour period, which exceeded the flash flood guidance shown in the purple line.

Below is a listing of 24-hour rainfall totals from area observers ending at 7 AM CDT 08/20/09 :
