You'll want to pay attention to the skies this Fourth of July, but not just for the fireworks.
The holiday will see scattered showers and thunderstorms in the Chicago area met with a heat advisory for several counties, mainly inland.
The day will be partly sunny with showers and thunderstorms likely at times, but not area wide. Any storms that do develop aren't expected to be severe, but could bring with them heavy rain and gusty winds.
The storms could fade after sunset, just in time for fireworks.
Temperatures are set to reach into the upper-80s and low-90s inland on Wednesday, but humidity levels will make it feel like 100 degrees. Those temperatures will be cooler along the lakefront.
A Heat Advisory is in effect from noon to 7 p.m. (CT) in McHenry, DeKalb, Kane, DuPage, LaSalle, Kendall, Grundy, Will and Kankakee counties in Illinois and Lake, Porter, Newton and Jasper County in Indiana.
The advisory warns of heat indices near 105 degrees.
"The combination of heat and humidity will lead to hazardous conditions, particularly for the elderly and those with pre-existing health conditions," the alert read.
The heat is expected to continue Thursday with Heat Index Values expected to reach between 100 and 105 degrees. Scattered showers and thunderstorms will also be possible at times.
The week will likely end on a mostly sunny and breezy note with temperatures cooling into the low-80s inland and low-70s along the lakefront.
