Thunderstorms were lashing parts of the Midwest with potent winds and large hail on Tuesday afternoon, only days after an outbreak of strong tornadoes tore through parts of the central U.S. and blizzard conditions affected the northern tier. The similarly volatile storm system was expected to deliver extreme weather conditions to many of the same states on Tuesday and into Wednesday.

On the warmer side of the storm system, more than a dozen states, from Wisconsin to Texas, were again at risk for severe weather. The most probable regions expected to be impacted by damaging winds and tornadoes were in Iowa, Illinois, Missouri and Arkansas.

Here’s what to expect around the country.

Storms had arrived in Iowa and Illinois.

By early afternoon as storms moved over eastern Iowa, there were reports of destructive, windblown baseball-size hail in towns in northeast Illinois, according to the National Weather Service in Chicago, which also noted that gusts could be as high as 80 miles per hour on the border of Ogle and Lee Counties.

“This is a DANGEROUS storm,’’ the service warned. “If you’re in it’s path, take cover away from windows!” The hail, measuring about three inches in diameter, was the largest to fall in the Chicago area since a July 2020 storm, the service said on Twitter.

Officials elsewhere had also cautioned residents in affected areas to be prepared for deteriorating conditions.
