In the late morning of the 25th, a line of storms from eastern Kansas restrengthened as they slowly moved northwest. These storms dumped upwards of 6 inches of rain near Hoxie and caused flooding in various locations in northwest Kansas. As the day progressed, more storms began firing to the west from the outflow of this initial system. In the afternoon of the 25th, these new slow moving, high precipitation thunderstorms forming across eastern Colorado and northwest Kansas moved northeast. Overnight on the 25th, the storms began to back-build, and cause flooding in extreme northwest Kansas. Flooding continued until at least the 28th but the damage it caused took even longer to repair.
