- The severe weather threat, which began on July 13, is expected to persist through July 16, affecting millions of residents across several states.
On July 14, the Chicago area experienced multiple weather alerts as fierce winds and heavy rains impacted the region. A severe thunderstorm warning was issued for LaSalle, Will, and Grundy counties, as well as part of Kendall County, until 00:30 LT on July 15.

FOX 32 Chicago reported that roofs were torn away from buildings, including the Rock and Roll Museum. Many roads in the area have been closed, and police are urging people to stay away.
“Minneapolis will likely have their severe storms for the Monday morning commute,” said AccuWeather meteorologist Brett Roys. “The storms in Milwaukee and Chicago will be closer to the evening commute and much of Michigan and Indiana, including Detroit and Indianapolis, will have their highest risk of severe thunderstorms during the overnight hours.”
“Across the Northeast, thunderstorms will have plenty of heat and humidity to work with along with energy that may be left over from the storms that affect the Ohio Valley on Sunday.” However, he noted that the risk of hail and tornadoes is negligible in the Northeast, with damaging winds and downpours being the main hazards, Roys added.
Looking ahead to July 16, the strongest storms will be from central Illinois to northwestern Ohio, where storms will be capable of producing flooding downpours, damaging wind gusts, and hail, according to Roys.
The severe weather outbreak follows a series of intense storms on July 13, which brought reports of tornadoes in North Dakota and Minnesota, as well as softball-sized hail and hurricane-force wind gusts.
As of July 15, more than 15 million people from Iowa through portions of southern Wisconsin, northern Illinois, and northern Indiana have been placed in a Level 3 out of 5 risk of severe weather. This includes major cities such as Chicago, Aurora, and Rockford in Illinois, Fort Wayne in Indiana, and Des Moines in Iowa.
