Missouri wakes this Saturday to brisk air sweeping across St. Louis as low clouds drift above damp streets. A cool northwest breeze rattles loose branches, a quiet hint of the stronger winter pattern building to the west. Roads stay dry early, but conditions may change quickly as returning travelers fill I-70, I-55, and I-64 through the afternoon.
According to the National Weather Service, temperatures reach the upper 30s today as clouds steadily thicken. By midday, moisture pushes north from Arkansas and southern Missouri, creating an early “winter tease” for the metro. Snow becomes increasingly likely Saturday afternoon, with a possible rain-to-snow changeover near the evening commute. Meteorologists now expect 1–3 inches in parts of the region, especially north and west of the city. Plan extra time if traveling after 2 p.m., and watch for slick spots on bridges as temperatures fall toward freezing.
Models hint at a much colder December pattern taking hold across the Midwest beginning December 2. The broad trough shown on national guidance brings below-normal temperatures to Missouri and Illinois through the first week of December. To be fair, not every day supports snow, but the setup clearly favors more active winter weather—especially for communities preparing for early-season cold snaps.
Saturday night brings lingering light snow or a mix with rain, tapering after midnight. Sunday turns mostly cloudy and colder with highs near 32°. Monday brings another slight chance for snow, followed by a gradual warming trend Tuesday and Wednesday with highs returning to the upper 30s and lower 40s.
