DES MOINES, Iowa - Large hail has been reported in Nebraska as severe weather with a potential for tornadoes moves through a swath of Midwest states.
The National Weather Service says the highest risk for severe weather Tuesday is centered in parts of northern and eastern Nebraska, western and southern Iowa, and northeast Missouri. Officials say there's the potential for a derecho system, which is a storm of strong straight-line winds spanning at least 240 miles.
An outbreak of severe thunderstorms also is expected in parts of Illinois, Kansas and South Dakota. Officials say baseball-size hail was reported Tuesday afternoon in northeast Nebraska.
The severe weather threat arrives amid an unusually quiet late spring, with far fewer documented tornados in May than in previous years.
