Heavy Rain and Flooding Wednesday, July 21st, In North Central Kansas

During the early to mid morning hours on Wednesday, July 21st, a persistent area of showers and thunderstorms dumped very heavy rainfall across parts of north central Kansas. As seen in the radar-estimated precipitation map below, the heaviest rain of 2 to 5+ inches targeted southern Smith, northeast Osborne, and much of Mitchell Counties. With most of this rain inundating the North Fork Solomon River basin, flooding was imminent, and the river at Portis rapidly rose to over 7 feet ABOVE flood stage by the noon hour.
