St. Louis, Missouri – A sharp shift toward dangerous winter conditions is expected across Missouri beginning Thursday, with Arctic cold, subzero wind chills, and potential snow creating travel and safety concerns through the following Wednesday.
According to the National Weather Service Climate Prediction Center, Missouri is expected to fall into a below-normal temperature pattern during the Jan. 15–21 period as Arctic air expands southward into the central United States. While precipitation is projected to remain near seasonal levels, the intensity of the cold will allow ice to persist on roads and bridges even after light snowfall.
Northern Missouri, including Kirksville, Hannibal, and Chillicothe, faces the highest risk for subzero wind chills during overnight and early morning hours. Prolonged cold could strain heating systems and increase the risk of frozen pipes. Even minor snow accumulations could quickly create slick conditions along U.S. 36 and U.S. 63.
Central Missouri, including Columbia, Jefferson City, and Sedalia, is also expected to see temperatures plunge well below normal. Drivers along Interstate 70 may encounter icy patches during morning commutes as repeated overnight freezing limits melting. In western Missouri, including Kansas City and surrounding suburbs, bitter cold combined with occasional snow could lead to hazardous travel on Interstate 35 and Interstate 435.
Southern Missouri, including Springfield, Rolla, and Poplar Bluff, may avoid the coldest readings but will still contend with a prolonged stretch of sharply colder weather. Elevated roadways and rural routes remain especially vulnerable to black ice.
Residents are encouraged to prepare now by checking furnaces, insulating exposed pipes, and stocking vehicles with winter emergency supplies. Limiting outdoor exposure during the coldest overnight hours will be critical if wind chill advisories are issued.
Cold-related alerts and possible winter weather advisories may be expanded as confidence increases, with additional updates expected as the Arctic pattern settles across Missouri late next week.
