Strong to severe thunderstorms moved into eastern Oklahoma during the early morning hours of the 15th. The strongest storms produced hail up to golfball size. These storms dissipated by late morning.
Another round of strong to severe thunderstorms erupted over central Kansas during the afternoon of the 15th, as an upper level disturbance translated into the area from the west-northwest.
