During the afternoon and through the evening two groups of thunderstorms progressed across Northwest Kansas.  One group crossed into Kansas from Colorado behind a cold front, while the second group moved north across the forecast area east of the front, expanding in coverage.  The storm activity moving in from Colorado was responsible for most of the thunderstorm wind gust reports. One storm that moved across Cheyenne County Kansas produced significant straight-line wind and wind-driven hail damage. A swath of crops between 5 and 10 miles wide was completely destroyed.  Straight-line winds blew down large cotton wood trees in Sherman County.  In addition there were multiple reports of thunderstorm wind gusts above 70 MPH, with a peak gust (estimated) of 90 MPH west of St. Francis.  The largest hail reported was apple size in Oakley.
