A major winter storm will impact the area through tonight, and as a result, winter storm warnings and winter weather advisories have been posted for the entire region. A variety of wintry weather is expected to occur, including freezing rain, snow, and sleet. Snowfalls of 6 or more inches are expected across northern and western Missouri and west-central Illinois, but the precipitation will mix with and become increasingly dominated by freezing rain and sleet heading further to the south. Significant ice accumulations are anticipated for parts of southern Missouri and into southern Illinois. (Please visit http://weather.gov/lsx for more information.)
