Missouri greets the morning under thick clouds, with damp air settling over the St. Louis region. Pavement stays cool, and a gray sky hints at changes ahead.
Conditions stay quiet early, but rain arrives Thursday, becoming widespread by late morning. Roads turn slick quickly, especially along I-70, I-55, and downtown interchanges. Winds increase through the afternoon, with gusts pushing past 30 mph at times. Plan extra travel time and expect reduced visibility during heavier showers.
Temperatures climb into the mid-50s Thursday, but colder air follows fast. As rain tapers Thursday night, skies clear and temperatures drop sharply. Lows fall near 25 degrees by early Friday, setting the stage for a freeze. Any lingering moisture may refreeze on untreated roads, bridges, and overpasses.
Friday brings sunshine but a colder feel. Highs struggle near 40 degrees, with brisk west winds adding a winter bite. Dress for wind chill if heading out early.
Friday night stays dry but cold, with lows near 34 degrees. Patchy frost is possible in sheltered areas. While snow is not expected locally, the sharp warm-to-cold transition signals an early winter weather pattern setting up across the Midwest.
Saturday offers a rebound. Sunshine returns, and highs climb back into the mid-50s, making travel smoother for holiday plans. Saturday night cools again, though conditions remain dry.
Sunday stays mostly sunny, with highs near 46 degrees. Roads remain dry, and no winter precipitation is expected during peak Christmas Travel hours.
