Strong to severe thunderstorms will develop in northern Nebraska by mid to late afternoon, and move across parts of eastern Nebraska and southwest Iowa through the evening. The strongest storms may produce areas of significant damaging wind and hail, flash flooding, and a chance for a few brief tornadoes.
The greatest chance for severe weather is southwest of a line from Niobrara to Norfolk to Omaha to Clarinda…between 6 PM and 11 PM. The greatest chance for isolated flash flooding is generally along or just south of this line.
