Missouri starts the day shrouded in a thick, milky layer of dense fog as warm rain taps lightly against windshields across the St. Louis region. Streetlights glow in the haze, and wet pavement reflects each passing car—an early clue that travel will demand extra caution as Thanksgiving movement ramps up across the metro.
A Dense Fog Advisory remains in effect until 9 a.m., with visibility dropping to a quarter mile or less at times. Drivers should expect slow pockets along I-64, I-44, and the river bridges before the fog gradually lifts. Rain continues through the morning and early afternoon, creating a damp, sluggish start to the final weekend before Thanksgiving.
Today brings widespread rain, steady northeast wind, and temperatures in the mid-50s. Travel delays remain possible through the midday hours, especially for early outbound holiday traffic. By evening, rain tapers, cloud ceilings lift, and conditions ease for local plans.
Saturday delivers a welcome break—sunny skies and highs near the upper 50s offer an ideal window for last-minute yard cleanup, grocery runs, or early decorating. Sunday stays quiet as well, with mild air and comfortable travel conditions region-wide.
But models hint at a Winter Tease early next week. A surge of moisture Monday could bring another round of rain, and a stronger cold push behind it may trigger a brief rain-to-snow changeover somewhere in the Midwest between Tuesday and Wednesday. No St. Louis snowfall is confirmed yet, but the pattern favors sharper temperature drops as Thanksgiving approaches.
Looking nationally, long-range guidance signals the potential for heavy snow across parts of the northern and central U.S. between November 25 and December 3. Anyone traveling long distance should check updates frequently—winter may arrive sooner than expected.
