The Chicago area is set to see an arctic chill this weekend that could bring the coldest air of the season so far.
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 Friday with a chance for light rain and fog.
Saturday stays mild with temps in the mid-30s. There is a chance for rain early but another system will likely bring snow during the afternoon and evening hours as temperatures cool, with 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 in the Michiana snow belts and while it's not quite clear how much snow could fall, some spots could see several inches. Chicago could see anywhere from 2 to 4 inches while parts of northwest Indiana and areas south of the city could see up to 5 inches.
After the snow, the area will likely 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.
