The time frame between the early morning hours of Tuesday the 24th into the day on Wednesday the 25th brought widespread heavy rainfall and flooding to much of North Central Kansas, in what turned out to be the second of three significant heavy rainfall events within a 2-week span. This event unfolded in two distinct waves, with the heaviest accumulations focused from the evening of the 24th into the early morning hours on the 25th. For the 24-hour period ending on the morning of the 25th, widespread rainfall amounts of 2.5 to 4 inches were common across the six-county area, with isolated reports of  5 inches or higher in southern Osborne County. Officially measured 24-hour totals included 4.03 inches at Lebanon, and 3.61 inches at Ionia. Not surprisingly, both areal and river flooding quickly became an issue for parts of the area. Several roads were covered in water for at least a short time in Smith, Jewell, Osborne, and Mitchell Counties. River flooding impacted various gauges, including the Solomon River at Beloit, North Fork Solomon at Portis, and South Fork Solomon at Osborne, along with the White Rock Creek near Burr Oak. Moderate flood stage was reached at Beloit and Portis, with Portis cresting 6.6 feet above flood stage on the evening of the 25th. The White Rock Creek near Burr Oak crested 6.3 feet above flood stage around the same time.
Despite occurring during the peak time of year for severe thunderstorms, no damaging winds, hail or tornadoes were reported within the local area, although brief funnel clouds were sighted in the Glen Elder and Lebanon areas.  It was a rather close call for North Central Kansas, however, as a significant severe weather outbreak pounded a corridor from central Kansas to northern Texas, including several damaging tornadoes. The primary reason that severe weather focused farther south involved the track of the parent mid-level low pressure system, which slid from west to east across the central third of Kansas. This kept the primary east-west oriented surface warm front, and thus substantial low-level instability, just south of North Central Kansas.
