ST. LOUIS, Missouri — Dawn breaks clear and calm across the Mississippi River, with city lights fading under a pale golden sky. It’s a crisp, quiet start to what will be a bright and mild stretch — the kind that makes mid-November feel borrowed from early fall. Highs will climb into the mid-60s to upper 70s through the weekend before a stronger system brings showers and a noticeable cooldown early next week.
According to the National Weather Service in St. Louis, Thursday begins mostly sunny with highs around 64°F, then steadily warms through Saturday as southerly winds return. Friday will top out near 75°F, while Saturday could hit 78°F in parts of the metro and along I-70, ideal for yard work, outdoor markets, or early holiday decorating. Nights will stay mild, hovering in the 40s and 50s with patchy river fog possible near Alton and Arnold.
By late Sunday, clouds build ahead of a developing front sweeping in from the Plains. Rain and isolated thunderstorms may arrive Monday, dropping temperatures back into the 50s. Models hint at a cooler trend for Thanksgiving week, though no early snow threats are on the table yet.
For now, St. Louis sits squarely in the calm between systems — bright skies, light breezes, and comfortable warmth before the seasonal chill reasserts itself as November deepens.
