Overview

A rare early season winter weather event occurred on Veterans Day with snowfall amounts ranging from 1 to 3 inches. A robust surge of arctic air blasted into the region during the afternoon hours. The colder temperatures caused the rain to change to a brief period of sleet or freezing rain, before quickly transitioning to snow. The changeover occurred around noon in our far northwest up near Mount Vernon, IL and shortly after 6 PM in the Hopkinsville, KY area. Flash freeze conditions were observed on area roadways as gusty northwest winds accompanied the temperature drop into the 20s. Although road surface temperatures were well above freezing to start, travel impacts quickly occurred as we approached sunset and after. Many area roads became slick and hazardous, which resulted in numerous accidents and slide offs. Portions of I-57 and I-24 were temporarily closed due to inclement road conditions during the evening hours. The poor road conditions continued into the next morning due to very cold temperatures down into the teens which caused any untreated roads to become a sheet of ice.
