CHICAGO (CBS) — After another mild day Monday, an arctic blast is targeting Chicago.
The coldest time frame will be Thursday morning with wind chills ranging from -5 to -15.
In an earlier time frame, there is a chance of some drizzle on Sunday evening, as moisture moves our way from the Gulf of Mexico. The center of the storm will remain well south of the Chicago area, so only drizzle is expected, mainly in Northwest Indiana and south of the Kankakee River Valley.

This Arctic cold snap will be short-lived as temperatures moderate by the weekend.
