St. Louis is starting Saturday with clear skies and temperatures around 46 degrees, but the morning chill will quickly give way to a sunny afternoon near 76. Winds will stay light from the southeast, making it an easy day for errands, patios and outdoor plans across the city.
According to the National Weather Service, dry conditions are expected this weekend, with a low near 50 Saturday night as skies turn partly cloudy. No watches, warnings or advisories are in effect for the St. Louis area.
Sunday Brings The Warmest Weekend Afternoon
Sunday should be mostly sunny with a high near 79, followed by a mostly cloudy night and a low around 53. The bigger planning note is the temperature swing between cool mornings and warm afternoons.
Warm, Mostly Dry Weather Holds Through Friday
The mild pattern is expected to linger into next week, with highs remaining in the 70s each day. Clouds will increase at times, but rain chances remain minimal through Thursday before rising to 10–30% Friday.
Low-lying areas could still see a little morning fog from time to time, particularly when skies clear overnight. For most St. Louis residents, though, the forecast is straightforward: bring a light layer early, keep the sunglasses handy by afternoon and enjoy an unusually warm late-October stretch.
