DES MOINES, Iowa (AP) — Storms are erupting across the Midwest, bringing heavy rain, large hail and the threat of tornadoes to portions of South Dakota, Nebraska and Iowa.

Severe thunderstorm warnings were issued in all three states late Thursday afternoon, with a tornado warning in north central Nebraska.

The National Weather Service says a storm near Omaha, Neb, produced softball-size hail and winds of more than 65 mph. In Dixon County in northeast Nebraska, strong winds and hail broke out some windows in buildings in Waterbury.

Winds of more than 55 mph and heavy rain were reported in western Iowa in Griswold.

Forecasters say widespread thunderstorms are expected into Thursday night in southeast South Dakota, eastern Nebraska and western Iowa as a cold front moves across the region.
