A nearly stationary frontal boundary stretched from northern Wisconsin to the Texas panhandle during the evening hours of Wednesday, May 23rd, through the morning hours of May 24th. Severe storms developed late Wednesday afternoon along the front, and dropped hail up to 1.00" in diameter across portions of northeast Kansas. By late evening, the threat for hail subsided across northeast Kansas, and forecasters began to focus more extensively on the potential for flash flooding, as well as creek and river flooding across north central and northeastern portions of the state.
Reports of flash flooding began as early as approximately 8:30pm in Republic County, and continued throughout the night across the region. Over 4" of rain was reported to have fallen at many locations by Thursday morning. A preliminary summary of 24 hour precipitation reports from Cooperative Observers and Automated Surface Observation Stations through 9 AM the 24th can be found below.
Rivers and Creeks began to respond to the heavy rainfall early Thursday morning, and many sites were reporting water levels rising to, at, or above bankfull in central and eastern portions of Kansas.
