A day after tornadoes and strong storms walloped the Midwest, killing at least five people in Oklahoma and causing massive damage throughout the region, forecasters warn that more severe weather is on the way.
The National Weather Service is forecasting the development of tornadoes, large hail and damaging winds over parts of the upper Mississippi Valley this afternoon, with northeast Iowa, Southeast Minnesota and central and southwest Wisconsin areas most likely to be affected.
The National Weather Service received 122 reports of tornadoes in the Midwest on Saturday and early Sunday, but could not confirm exactly how many there were. Kansas Gov. Sam Brownback told CNN on Sunday that 97 tornadoes touched down in his state.
According to CNN meteorologist Alexandra Steele, Green Bay, Chicago, St. Louis, Little Rock and Houston were among the cities "that could see isolated tornadoes, large hail and damaging winds" on Sunday.
