CHICAGO — Scorching temperatures matched a record level in the city Tuesday, according to the National Weather Service.
The weather service said it recorded a 95-degree reading at O'Hare Airport in the afternoon, tying the 30-year-old record set on Sept. 10, 1983.
On Wednesday, the weather service predicts a 40 percent chance of showers, which could provide a respite from the heat and help cool things down. A high of 87 degrees is expected on Wednesday, and a high of 75 degrees is expected Thursday.
On Friday, things could feel a little more like fall, with a high of 63 degrees, according to the weather service.
Metra issued a heat alert and warned that commuters could experience delays of 10 to 15 minutes for trains during the next few days because of the weather. During periods of extreme heat, Metra operates at slower speeds to make up for heat-related stresses on the tracks, the agency said in the alert.
The conditions could put extra stress on groups at risk for heat illness, such as those who work outside, the elderly, young children and pets, the weather service warned.
