Missouri – Cold air cuts across the Mississippi River this morning, crisp enough to sting exposed skin. Side streets sit quiet, but winter is lining up fast, and the calm won’t last long as snow and dangerous cold close in.
A Winter Storm Watch remains in effect from late Friday night through Sunday morning for the St. Louis metro, including parts of southwest Illinois. A Cold Weather Advisory follows from late Friday night into Saturday. According to the National Weather Service, heavy snow is possible with totals between 4 and 8 inches, paired with sharply falling temperatures.
Snow is expected to begin late Friday night and intensify Saturday. Travel could become very difficult across the region, especially along I-70, I-64, I-55, and the Poplar Street Bridge. Gusty winds may reduce visibility at times, while snow-covered lanes create uneven, slick driving conditions.
Cold adds another layer of concern. Wind chills could dip as low as 15 degrees below zero, increasing the risk of frostbite and hypothermia if drivers become stranded. Snow may continue while the cold peaks, allowing ice to bond quickly to untreated roads and sidewalks.
Saturday stays locked in winter. Highs hover near 14 degrees, limiting any melting. Even brief daytime softening could lead to flash freezing after sunset, leaving parking lots, bridges, and neighborhood streets dangerously slick.
Sunday trends quieter but remains cold, with lingering snow chances early. Looking ahead, national outlooks point to colder-than-normal conditions persisting into early next week, with additional precipitation signals developing across the central U.S.
Residents should prepare now. Delay unnecessary travel, stock vehicles with winter safety kits, and dress in layers if heading outside. Check on vulnerable neighbors and bring pets indoors.
