The National Weather Service issued a wind chill advisory that began Tuesday evening.
The wind chill advisory is in effect for all of northern Illinois and most of northern Indiana through noon Wednesday.
Temperatures are expected to drop to -6° in the city and -15° in the far western suburbs, with wind chills between -20° and -35°.
Winds this cold can cause frostbite to exposed skin in as little as 30 minutes.
If you must be out Tuesday evening or early Wednesday, limit your exposure and dress in layers to protect yourself from extreme cold, including a coat, hat and gloves.

On Wednesday morning, there will be a low in Chicago of -6°C, which will be the coldest temperature in the city since Feb. 7 of last year.
Wednesday afternoon will be mostly sunny with highs in the 1920s and subzero wind chills for much of the day. Less cold Wednesday evening thanks to the return of a southerly wind. The lows will be in the teens and the highs on Thursday will be in the low 30s.
As the next system moves, it encounters this extremely cold, dry air mass. It will therefore weaken, and not much systemic snow is expected. The wild card will be any lake-enhanced plumes that settled from Thursday night through Friday.
