Missouri — Damp pavement reflects streetlights as mild January air hangs over eastern Missouri. It feels more like March than Winter, for now. Southwest winds brush across neighborhoods, and clouds thicken as the next weather shift lines up.
Temperatures climb quickly today, topping out near 61°F in St. Louis. Sunshine mixes with passing clouds, but gusty winds signal change. By tonight, cooler air settles in, dropping lows near 36°F. Roads stay dry, though drivers may notice breezy conditions on bridges and open stretches of I-70 and I-64.
Wednesday stays quiet and mild, with highs near 59°F. Clouds increase late, and rain chances arrive after sunset. This marks the start of a wetter stretch that continues into Thursday.
Thursday brings the main Weather Alert window. Rain becomes widespread by afternoon, with precipitation chances near 90%. Expect wet roads, reduced visibility, and slower commutes during peak travel hours. Highs reach 63°F, keeping everything liquid for now. No ice is expected, but ponding on roadways is possible during heavier rain.
Rain lingers into Thursday night, then tapers Friday. Friday stays cooler, with highs near 56°F and scattered showers possible. As colder air arrives late Friday night, lows fall toward 36°F. Any leftover moisture could refreeze on untreated surfaces, especially early Saturday.
