Overview

Surface low pressure to our south and an upper level system combined to bring a mix of Wintry weather across the Ozarks. Most of the area received rainfall throughout the evening of the 22nd, with a period of freezing rain prior to the changeover to all snow after midnight. The primary snow band set up along the Interstate 44 corridor from southwest into east central Missouri where 1 to 2.5 inches of snowfall occurred. The warm ground kept the ice from glazing on the roadways, but a glazing of ice did occur in some locations on elevated surfaces.
