The month of August has proven to be one of the wettest months in quite some time over a large part of Southwest Kansas. Multiple heavy rain episodes, thanks in part to a persistent tropical airmass and several strong cold fronts, have resulted in as much as 8 to 14 inches of total rainfall for the month! Of particular note, the small region of Southwest Kansas encompassing parts of Hodgeman County, eastern Ness County, most of Rush County, and much of Pawnee County have seen the greatest accumulation of rain since the beginning of the month (see map). In this area, multiple 2 to 4" rain events tracked across this area on August 13th, 17th, 18th, and 20th. Excessive rainfall on August 19-20th caused the Buckner Creek to flood near Burdett. The creek went into flood stage around 11am Sunday, August 21st and crested at 19.2 feet early Monday morning, Aug. 22nd.
A few cooperative observer sites have already set August rainfall records, including Ness City (9.09"), Alexander (12.87"), McCracken (9.73"), and Loretta (7.66"). An updated article will be written with a final summary of this months impressive rainfall.
More excessive rainfall is possible this weekend (Aug 25-27th), as another cold front moves into the region interacting with abundant low level moisture. Below is a map showing the forecast 5-day rainfall from the NWS Hydrological Prediction Center. This forecast was issued Thursday morning (8/24) valid Aug 24-29. As you can see in the forecast, widespread 1-3" or more rainfall is expected with this front across Southwest Kansas.
