(AP) — Forecasters say powerful tornadoes and large hail are possible Monday in parts of northern Kansas and southern Nebraska.

The Storm Prediction Center in Norman, Okla., says the nation’s midsection could see thunderstorms, hail and isolated tornadoes on Monday afternoon and evening. Forecasters say “intense supercells” are likely to form, which raises the risk for tornadoes and damaging winds.

The Storm Prediction Center says a large section of the central U.S. could see severe weather Monday, including Kansas City, Mo.; Omaha, Neb; Wichita, Kan.; St Louis and Indianapolis.

Forecasters say the greatest risk for severe weather is in north central Kansas and south central Nebraska.
