...Scattered Slick Spots Possible for the Monday Morning Commute... Patchy fog will develop across much of central Illinois after midnight. With temperatures once again dropping into the teens, the fog may become thick enough to create scattered slick spots on roads, overpasses, parking lots, and sidewalks. Motorists are advised to drive with caution late tonight into Monday morning. Be prepared for poor visibility at times and a few slick spots on area roadways. The fog will dissipate by mid to late morning.
