Remember those 90-degree temperatures Chicago was supposed to get a couple weeks back with 105-degree heat indexes?
They're likely here.
The temperatures felt Saturday could be the beginning of a stretch of high temps that may not move away until next weekend.
By 9 a.m. Saturday, the official temperature at O'Hare International Airport registered at 78 degrees -- and climbing.
Highs Sunday will be in the mid-90s and will feel like 100 to 105 degrees. And that trend may continue untile next Saturday.
Chicago's Office of Emergency Management reminds residents to drink plenty of water during periods of high heat. Check on the elderly and do not leave pets unattended or without water, the OEMC warns.
"Extreme heat and humidity are more than an inconvenience. They are dangerous and can be deadly," said Dr. Bechara Choucair with Chicago's Department of Public Health.
Places for the public to stay cool include 75 public pools, any Chicago Public Library branch, police stations, park district buildings and 19 senior centers.
