Forecasters say severe storms are likely Monday in parts of the Southern and Great Plains states, with tornadoes and very large hail a possibility in some areas.

The Storm Prediction Center in Norman, Oklahoma, says the greatest risk for bad weather is in Arkansas, Louisiana, Oklahoma and Texas. But forecasters say the storms could stretch into parts of Missouri and western Illinois, where isolated tornadoes can't be ruled out.

In all, about 41 million people from Houston to Des Moines, Iowa, are at risk for some type of stormy weather Monday.

A day earlier, tornadoes, hail and strong winds hit parts of Nebraska, Kansas, Oklahoma and Texas, but no major damage was reported.
