A Severe Thunderstorm Warning is in effect for LaSalle and DeKalb counties until 7:15 p.m.
The National Weather Service has also issued a Severe Thunderstorm Watch for Cook, De Kalb, DuPage, Grundy, Kane, Kendall, Lake and LaSalle counties until 10 p.m.
The greatest risk for severe weather in the Chicago area will be between 6 p.m. and 10 p.m., ABC7 meteorologist Phil Schwarz said.
The primary risks with any storms that develop Tuesday afternoon will be strong winds and torrential rains. Tuesday’s tornado risk is lower than Monday, Schwarz said, when seven tornadoes touched down in northern Illinois.
Areas north and west of Chicago are under an “enhanced” risk of severe storms, a level 3 out of 5, according to the Storm Prediction Center. These areas also saw the worst storm damage on Monday. Areas along the lakefront, the south suburbs and northwest Indiana are under a “slight” risk of severe weather, a level 2 out of 5.
Highs will rise into the 90s Tuesday, though heat indices across the area will make it feel as hot as 110 degrees, meteorologist Phil Schwarz said. While Tuesday’s high isn’t necessarily the hottest temperature of the year so far, she said it may be the highest heat index readings so far this year.

The National Weather Service warned that the hot and humid conditions could lead to an increased risk of heat exhaustion or heat stroke. The weather agency advised people to limit strenuous outdoor activities during the warmest part of the day.
“The best way to protect yourself against the heat is to drink plenty of water and stay in air-conditioned buildings as much as possible,” said Dr. Jennifer Satchi, chief medical officer at the Chicago Dept. of Public Health.
Cooling centers and splash pads will be available for residents to find relief from the extreme heat.

Open 9 a.m. – 5 p.m. Visitors are required to wear a face covering while in the cooling areas.
Residents can also find relief in one of the city’s more than 75 Chicago Public Library locations and more than 30 Chicago Park District fieldhouses, as well as splash pads and pools at specific locations.
High temperatures and humidity can pose a health and safety threat, officials said.
“Check on your neighbors during extreme heat, especially if there are seniors, families with young people, people with special needs, or living alone,” said Rich Guidice, executive director of Chicago’s Office of Emergency Management and Communications.
The steamy day had Lincolnwood Parks and Recreation Supt. Anna Koperski-Walsh on the lookout for heat-compromised bathers at the Proesel Park Family Aquatic Center.
“People who may be looking like they are sleeping, but they will not be asleep. Individuals who have been sitting in the sun for a long period of time and haven’t moved, and anyone looking like they’re kind of ill at the moment,” she explained.
Heat exhaustion is a milder form of heat-related illness that can develop after several days of exposure to high temperatures and inadequate or unbalanced replacement of fluids. Heatstroke is more serious and occurs when the body starts to lose its ability to regulate itself.
The telltale signs of heatstroke are:
If you see someone suffering from heatstroke, call 9-1-1 immediately and then try to move the person into a cool place and cool the person with water.
