St. Louis, MO – Fall weather settles perfectly over the St. Louis metro today as sunny skies and mid-70s temperatures mark a pleasant Columbus Day. Commuters and families heading outdoors can expect light winds and comfortable humidity — ideal for festivals, pumpkin patches, or a day at the park.
According to the National Weather Service, high temperatures will climb through the week, peaking near 81°F by Wednesday before cooling slightly heading into the weekend. Light south and east winds will keep conditions calm through Thursday, offering great travel weather for both Missouri and Illinois residents across I-70 and I-64.
By Friday, a weak front introduces a 30% chance of showers and thunderstorms, mainly in the afternoon. Saturday remains mostly sunny with highs near 80°F, though another round of light showers could develop by Saturday night. Sunday brings a gradual cooldown into the low 70s — a reminder that fall’s chill isn’t far behind.
Drivers are advised to check local forecasts before weekend road trips, especially if traveling toward rural counties or leaf-viewing destinations across the Ozarks or southern Illinois.
