St. Louis, Missouri – A strong push of Arctic air is expected to settle into central, eastern, and southeastern Missouri beginning Thursday, bringing a prolonged stretch of well below-normal temperatures while precipitation chances remain limited through early next week.
According to the National Weather Service and NOAA’s Climate Prediction Center, much of Missouri is forecast to see below-normal precipitation through Monday. While rain chances remain low, temperatures are expected to drop sharply, setting the stage for widespread frost and repeated freezing nights across the region.
Central Missouri, including Columbia, Jefferson City, and Rolla, is expected to experience multiple overnight periods with temperatures falling to or below freezing. Sub-freezing conditions may last several hours at a time, increasing concerns for exposed pipes, pets, and sensitive vegetation. Clear skies and light winds behind the Arctic front will allow temperatures to fall quickly after sunset.
Eastern Missouri, including St. Louis, St. Charles, and surrounding metro communities, will also see a heightened risk for hard freezes. Even where daytime sunshine is present, temperatures are expected to struggle to recover, keeping cold conditions locked in through the period. Bridges and elevated roadways may develop icy patches during the coldest mornings despite the lack of precipitation.
Southeastern Missouri, including Cape Girardeau, Sikeston, Poplar Bluff, and the Bootheel region, will see colder-than-normal nights that are unusual for mid-January. While this area may avoid the coldest readings seen farther north, widespread frost and periodic freezing conditions are likely, especially in rural and agricultural areas.
Daytime highs across the region are expected to remain suppressed, with morning wind chills making conditions feel even colder at times. Major travel routes including Interstate 70, Interstate 64, Interstate 44, Interstate 55, and Interstate 57 could see localized slick spots during early morning hours.
Residents are urged to take cold-weather precautions, protect pipes and plants, and check on vulnerable neighbors. This dry but unusually cold pattern is expected to persist into early next week, with freeze-related advisories likely as confidence increases.
