Dangerous storms packing hail and potential tornadoes were threatening large swaths of the U.S. on Monday, NBC News reported.
Plains states already got a taste of the severe weather: hail nearly twice the size of a quarter was spotted in Nebraska Sunday along with what appeared to be tornadoes.
The Great Lakes area could see severe thunderstorms on Monday afternoon and evening, with Chicago and Milwaukee in the threat area, according to The Weather Channel.
Severe thunderstorms are expected to hit the southern Plains, parts of Texas and the lower Mississippi Valley on Tuesday. Storms also were expected to produce potentially life-threatening tornadoes.
