More significant storms are predicted to strike the Plains Saturday afternoon and evening. The same storm system that produced a massive supercell tornado that destroyed a Kansas town, killing seven, is moving into the Dakotas and northern Texas. The epicenter of the storm is over southwestern Nebraska and western Kansas, according to the Weather Channel.

Tornadoes, large hail the size of softballs and damaging wind are predicted to strike those areas. Overnight, thunderstorms are expected to spread into western Oklahoma and into the Texas panhandle.
