A high impact storm system moved across Northwest Kansas. The storm system produced an environment that was favorable for any of the developing thunderstorms to produce a tornado, which led to multiple tornadoes occurring on this day.  The strongest tornado was rated an EF-1 which caused damage to the high school in Weskan.
Otherwise thunderstorms produced hail up to half dollar in size near Wallace, and wind gusts estimated up to 65 MPH near Campus.  The thunderstorms on this day were heavy rain producers, with rainfall amounts ranging from two to four inches.  This led to some towns having street flooding as the storms moved through.  One location near Weskan had flood damage a barn.
The repeated rounds of heavy rainfall over the Ludell area, combined with runoff being funneled into Beaver Creek from the area, caused flooding to occur at Ludell.  The flood waters also flooded the county road going east from Ludell that followed Beaver Creek to Herndon.
