The Chicago area is bracing for a weekend heat wave that could be dangerous.
An Excessive Heat Warning was issued Saturday morning following an Excessive Heat Watch issued Friday that is no longer in effect, according to the National Weather Service.
The Warning is scheduled to last until 7 p.m. Monday.
With peak heat indices forecast to reach near 105 degrees, experts warned that heat illnesses will be possible.
Afternoon highs will be in the mid-to-upper 90s Saturday through Monday. The evening should likely see lows in the low 80's on Saturday and Sunday night.
“Only minimal relief from the heat is expected at night with heat indices likely to remain in the 90s through the evening and possibly into portion of the overnight hours,” the alert reads.
That type of prolonged heat, combined with sunny skies, can lead to hazardous conditions, the NWS warned.

Residents are advised to drink plenty of fluids, stay in air-conditioned rooms and stay out of the sun. The heat will be particularly dangerous for elderly residents or those with pre-existing health conditions.
Residents can call 311 for well-being checks and cooling centers will be open at multiple locations around the city.
Chicagoans should also remember the signs of excessive heat exposure. People suffering from heat exposure may get dizzy and sweat excessively, but those with heat stroke don't sweat at all. Heat stroke may come with a throbbing headache or a rapid pulse, symptoms that may sneak up, so it's important to know the difference.
