Chicago could soon see some of the coldest air the city has seen so far the season.
While much of the Chicago area is expected to see above-average temperatures for the end of the week, a major cool down is in store for this weekend and early next week.
Temperatures will rise in the upper-30s and low-40s Thursday and Friday with a chance for rain both days.
Saturday stays mild with temps in the mid-30s. There is a chance for rain early but that rain will likely turn to snow as temperatures cool, bringing the potential for snow accumulation in some areas.
Colder conditions move in Sunday, with highs dropping to near 20 degrees and wind chill readings in the single digits.
Some lake effect snow showers are possible during the day before the area is set to see the coldest night of the season so far. Temps drop into the single digits with wind chills between -5 and -15 degrees.
The cold air remains Monday with highs in the teens and below-zero wind chills. Temps recover slightly Tuesday, returning to the low- to mid-20s.
