ST. LOUIS, MO - A major winter storm has blanketed parts of southeast Nebraska, northeast Kansas, southern Iowa, northern Missouri, and northern Illinois with snow, with some seeing 10 inches or more. The snow will be accompanied by winds of up to 45 mph, creating dangerous whiteout conditions on roads and interstates.
The St. Louis region saw rain and some strong thunderstorms Sunday evening in the warm sector of the major winter storm. By Sunday night, the cold air moved in thanks to gusty northwest winds and rain transitioned to wind-driven snow showers. Only minor snow accumulations, less than 1", are expected, mainly on grass. Snow totals do go up west of Warrenton and north of Troy, MO and Hardin, IL, where up to 2" is expected. Thanks to the blowing snow, visibility will be poor late Sunday into Monday so be sure to allow for extra travel time if you have to head out.
A Wind Advisory has been issued for much of the viewing area, including St. Louis, and is in effect until 6 a.m. Monday morning. Winds will be sustained from the northwest at 20 to 30 mph with gusts to 45 mph.
Snow tapers off overnight and then we'll have gradually clearing skies through Monday. Monday morning will be blustery with lows in the 20°s and wind chills in the teens.
