During the afternoon and evening hours of June 29th, scattered severe thunderstorms formed over the mid Missouri Valley, along and ahead of a cold front moving into the region. The approach of an upper-air disturbance from the northwest in conjunction with a moderately unstable air mass yielded a favorable environment for supercells and other organized storm structures which produced a considerable amount of large hail.
One supercell produced a 14.4-mile long tornado in addition to hail up to baseball size while tracking across northern Cedar County in far northeast Nebraska. Later in the evening, another supercell moved across the Omaha metro area, also producing hail up to baseball size.
