CHICAGO (CBS)–Chicago was bracing for another 100-degree day, prompting emergency officials to ask residents to take precautions.

The National Weather Service has issued a heat advisory for Tuesday that will last from 10 a.m. to 10 p.m. Temperatures are expected to be as high as 100 to 102 degrees, with heat indices between 105 to 110 degrees.

“During these high temperatures, we continue to urge Chicagoans to check on their neighbors, families, elderly and the disabled,” said Gary W. Schenkel, executive director of the Office of Emergency Management and Communications. “Residents and visitors should take the necessary precautions and plan accordingly.”

Chicagoans can call 3-1-1 for the nearest city cooling center, request well-being checks, and request rides to cooling centers, if needed.  Cooling centers are located within the six community service centers operated by the Department of Family and Support Services.  Chicago Public Libraries, park facilities and police stations also serve as cooling centers.

Rumbles of thunder are expected Tuesday evening, and showers and thunderstorms are expected to sweep through overnight into Wednesday.

The high Wednesday drops to 88 – which will likely feel more like 58. The high for Thursday is a comfortable 85, Friday 87, Saturday 88 and Sunday 89.


The Chicago Department of Public Health continues to encourage all residents to take extra precautions to avoid heat-related illness, such as heat exhaustion or heat stroke. Officials advise:

  • Avoid going out into the heat, especially in the hours around mid-day;
  • If you do go outside, wear loose, lightly-colored clothing and wear a hat with a brim;
  • Drink plenty of water– at least eight glasses a day;
  • Get into an air-conditioned space or a cooler part of the house, like a basement;
  • Keep shades drawn and blinds closed to block the sun;
  • Take cool baths or showers; use cool towels and washcloths to cool the skin;
  • Slow down, avoid or minimize physical exertion; and
  •  Don’t leave any person or pet in a parked car, even for a few minutes.
