Missouri wakes up under low gray clouds, with damp streets reflecting headlights and a sharp chill settling in behind the rain. The air feels heavy now, but colder changes move fast, and conditions tighten as the day progresses.
According to the National Weather Service, light rain tapers off early this morning around St. Louis, followed by clearing skies and falling temperatures. Gusty northwest winds reach up to 25 mph at times, pushing afternoon highs into the upper 40s before a steep drop later. Temperatures fall into the mid-20s by tonight.
That rapid cooldown raises a familiar January concern. Wet pavement from early rain may refreeze after dark, especially on bridges, overpasses, and untreated ramps. Drivers along I-64, I-70, and I-55 should watch for isolated slick spots late this evening and into early Sunday.
Skies turn sunny Sunday, but the air stays cold. Afternoon highs reach near 39, with a light breeze adding bite. Sunday night stays clear and cold again, dipping near the upper 20s. By Monday, calmer conditions arrive, and sunshine helps temperatures rebound into the lower 50s.
The warming trend continues into Tuesday, when highs approach 60 under partly sunny skies. That swing from rain to freeze to mild afternoons highlights the volatility of mid-January weather across the Midwest.
Regionally, colder air expands east while heavier snow targets the Great Lakes and interior Northeast. St. Louis avoids snow for now, but the freeze risk tonight remains the primary local impact.
By the end of January, daylight increases by about 40 minutes in St. Louis, offering brighter evenings despite winter’s grip.
Slow down tonight, watch shaded roadways, and plan for cold mornings ahead. Seeing icy patches where you live? Let us know what conditions look like.
