A small cluster of storms with a bow echo, moved east across eastern Kansas and northern Missouri, during the morning hours of June 19, 2010. This storm system packed a strong punch, with radar estimated velocities topping out in the 80 to 90 knot range at times.  While the majority of this air speed didn't translate down to the surface, numerous reports of 60, to as high as 70 mph winds, were common from St. Joseph, to Kansas City, Lees Summit, Chillicothe, Sedalia, Moberly, and Columbia.  This storm system remained intact long enough to cross the entire state of Missouri, making it a tri-state complex.
