CHICAGO — The Excessive Heat Warning will continue today over most of the Chicago area with Excessive Heat Advisories in effect in northwest Indiana calling for peak Heat Indexes in the 100 to 115-degree range. Excess heat Advisories will likely continue a good portion of the Chicago area Saturday and Sunday with heat Indexes generally in the 100-110-degree range, although there may be some slight relief right along and just inland of the Lake Michigan shoreline Saturday.

A cold front is forecast to sag south out of Wisconsin into northeast Illinois settling just south of Chicago tonight. The front is then expected to swing back north later Saturday and stay north until a stronger cold front sweeps through from the northwest late Sunday, followed by a not so warm and drier high pressure air mass that will bring more seasonable temperatures in the 80s the first half of next week.

The American Red Cross on Wednesday released its list of "Extreme Safety Tips":

  • Never leave children or pets in a vehicle – even for a few minutes. The inside temperature of a car can quickly reach 120 degrees.
  • Stay hydrated by drinking plenty of fluids throughout the day. Avoid drinks with alcohol or caffeine.
  • Slow down, stay indoors and avoid strenuous exercise during the hottest part of the day.
  • Wear loose-fitting, lightweight, light-colored clothing. Avoid dark colors because they absorb the sun’s rays.
  • Use a buddy system if required to work outdoors and take frequent breaks.
  • Check on animals frequently to ensure that they are not suffering from the heat. Make sure they have plenty of cool water and shade.

The Red Cross also says people without air conditioning should seek relief at public places such as libraries, shopping malls and movie theaters.

The Illinois Department of Public Health also urges residents to shower or bathe in cool water to lower body temperature, and check in on high-risk family members,  friends and neighbors. These could include seniors and people with chronic health conditions.

Cook County has set up cooling centers for residents in surrounding small towns. Click here for the full list.

The city of Chicago will also have cooling centers available in a handful of neighborhoods. See the list here.
