Missouri — Missouri air bites hard this morning as wind sweeps across bridges, parking lots, and riverfront neighborhoods, creating a sharp chill that stings exposed skin within minutes. Light snow flurries from earlier in the week have faded, but the December cold snap now tightening over St. Louis carries its own risks, especially for travelers stepping out early.
A Cold Weather Advisory remains active until midday, with wind chills dropping between 10 and 20 degrees below zero across parts of eastern Missouri and southwest Illinois. Northwest winds between 10 and 20 mph, with gusts near 25 mph, continue to drive temperatures into dangerous ranges. Meteorologists note that frostbite may occur in as little as 30 minutes without proper protection—an important reminder as holiday shopping ramps up and school families begin early Christmas travel.
Skies stay mostly clear today, but temperatures recover slowly. Highs approach the upper teens, though wind chills remain well below zero through late morning. Drivers along I-55, I-64, and I-70 should expect stiff crosswinds on higher overpasses and a “flash-freeze feel” on shaded stretches where the pavement never fully warms.
Monday begins a steady warmup, reaching the low 40s by afternoon under sunny skies. Winds relax, making travel easier for families heading out for mid-December events. By Tuesday, St. Louis climbs into the low 50s, offering a brief break from the winter sting and a window for errands, outdoor decorating, or prep ahead of next weekend’s potential pattern shift.
