-1F here in the NW suburbs.
Wind chill readings are supposed to be 20 below to 30 below zero in the morning.
Yeah, left work early in Sycamore to get home to Rochelle because we heard hwy 251 was being closed around Rochelle due to blowing/drifting, and they might close hwy 38. The wife was working at her store in DeKalb, and we both left, getting home 5 minutes apart. We hit three white-out areas on 38, two between Kishwaukee College and Creston, and one just West of Creston. Not fun.
Now we're supposed to get 3-5" more tomorrow, then turning "wintry mix" into Wednesday. Supposed to go to Rock Island Christmas Day. Well, maybe...
