Weather Story

Period of Snow Tonight-Early Wednesday

Timeline of Upcoming Dangerous Cold

Four Day Outlook

A clipper system will bring another round of accumulating snow to part of the area late this evening through early Wednesday morning, particularly for areas near and north of I-80 and highest near the Illinois-Wisconsin state line. This will cause untreated roads to become snow covered and slick and may impact part of the Wednesday morning commute! Some uncertainty remains on the exact position of the band and whether snow may develop farther south for a short period early Wednesday morning so be sure to check back for forecast updates!

A period of bitterly cold temps & dangerous wind chills is expected Thu night through Sat morning. Some areas will likely see actual temps remain below zero all day Fri! By Sat afternoon, temps will "moderate" to more typical very cold levels.

After some snow overnight into early Wed morning, look for more seasonable temps Wed. Gusty snow showers will accompany a cold front Wed evening, then a much stronger cold front will usher in the coldest air this winter Thu night.
