Get indoors, grab a cold beverage, and blast the A/C: Friday is expected to be the hottest day of the year, as a one-day heat wave could push the mercury over 100 leading into the July 4th weekend.
Temperatures are expected to be in the upper 90s, but could break into three figures, according to the National Weather Service. Worse yet, thick humidity is expected to make it feel even hotter. The heat index will register around 105 degrees in the afternoon.
The dew point, a measure of the level of moisture in the air, "is expected to be in the 70s, which will make everyone very uncomfortable,” weather service meteorologist Richard Castro told the Chicago Tribune.
The Sun-Times got a little cheeky with its warnings about the weather:
Whatever you do Friday, do not: Take a hot bath to de-stress; get stuck in a glass elevator; decide to have a marathon baking session in your studio apartment for an upcoming 4th of July picnic.
Triple-digit temperatures are rare in Chicago: the last time we had one was in July of 2005. There have only been five recorded temperatures over 100 degrees in the last 20 years.
Fortunately, we'll see a reprieve by the weekend. According to Weather.com, temps are expected to dip back down into the mid-80s on Saturday, and will hover around there through the holiday.
