“Once again, thunderstorms are expected to fire in parts of the northern Plains to Lower Great Lakes on Tuesday,” the National Weather Service said.
“A separate area of severe weather is possible in the Northeast. Large hail and damaging winds will be the primary threats. In addition, rainfall could be heavy enough to cause flash flooding and river flooding in the Midwest and Lower Great Lakes,” it added.
The storms forced the temporary closure of O’Hare International Airport, NBC Chicago reported.
Felled trees also led to traffic chaos across the city.
Meanwhile, in Wisconsin there was almost a foot of rain over the weekend.
The water-logged soil means additional rainfall is more prone to run off and cause rapid flooding of low-lying areas, officials warned.
Lightning strikes could also spark wildfires on the northern Plains, experts warned.
The massive West Fork Fire in Colorado is expected to burn for some time to come.
But after more than a week the raging blaze in Doce, Ariz., was expected to be fully contained tomorrow.
More than 500 personnel and three helicopters have battled to bring in it under control.
