Oppressive heat continues in the Chicago area into Northwest Indiana, prompting a heat advisory through 9 p.m. Wednesday.
Tuesday temperatures reached 96 degrees with a heat index of "uncomfortable."
We kid. The "feels like" temperature was 99 degrees, which is what the forecast predicts for Wednesday, Independence Day.
The heat index Wednesday and Thursday is predicted to soar well above 100 degrees.
Chicago's latest heat wave persists into the holiday, and the National Weather Service plans to place an excessive heat watch on Cook County Wednesday morning through the evening.
Hot, dry conditions keep driving up the fire risk for suburban fireworks displays, forcing multiple towns to cancel their shows. Plainfield, Wauconda, Round Lake, Antioch, Cary and Mundelein will reschedule their displays for a later date.
Holiday skies should look mostly sunny for much of the day, though there's a chance of thunderstorms in the afternoon.
Thursday temps settle back down to the mid-90s from a sweltering 100, but relief from the heat wave won't come until the weekend.
