A couple of upper-level perturbations that moved east/northeast across Oklahoma and extreme Southern Kansas interacted with a moisture-laden air mass to generate very heavy rains across South-Central & Southeast Kansas on the 23rd and 24th. Most of South-Central and Southeast Kansas received 2 to 3 inches from the morning of the 23rd through the morning of the 24th. For most areas, the flooding continued well into the 25th. No doubt, most of the rivers and creeks, primarily in South-Central & Southeast Kansas, rose to the occasion with most venturing into Minor Flood Country. However, 2 rivers ventured into Moderate Flooding Country. The more notable, by far, was the Neosho, along which the forecast points at Chanute, Erie, Parsons, and Oswego all achieved Moderate Flood status. The other was the Walnut, on which Winfield achieved Moderate Food status.
