A wintry mix of snow and sleet spread across the region during the afternoon and evening hours on January 11th. This was in response to surface low pressure that developed across the TX/OK region. This low would then move eastward and be located over the Missouri Bootheel by early evening on the 12th. Warmer temperatures at the surface and aloft began to move into southeast Missouri and far southern Kentucky during the late evening and early overnight hours on the 11th, with precipitation beginning to change over to rain. By later morning, any lingering precipitation had changed over to rain across the entire region. The heaviest snowfall amounts from this system remained northwest of our region across central portions of Missouri and Illinois. However, there were significant travel impacts during the evening hours and into the overnight hours in our region, as snow covered roads led to numerous accidents. Portions of I-57 and I-64 were even closed for a period of time in southern Illinois.
