A large upper level disturbance over the Rocky Mountains combined with a nearly stationary front over southeast Nebraska brought strong to severe thunderstorms to parts of the area for the second night in a row. This time the stronger storms were generally confined to southeast Nebraska where a multicell cluster of storms bowed out across southeast Nebraska. The storms did produce at least one weak tornado.
