The second round of snow this week is arriving in the Chicago area, with those who commute later in the evening potentially encountering traffic problems. The snowfall is expected to continue into the overnight hours before another round of snow showers is likely to reach the area by the early afternoon Saturday.

Storm total accumulations through Sunday evening look to reach 2-4 inches in Chicagoland, with isolated higher totals in Lake and McHenry counties.

Chicago is in for another teeth-chattering night as bitter cold grips the region, with wind chills plunging into the minus-10 range. If you're heading out, bundle up—it’s the kind of cold that stings.
