ST. LOUIS, MO – Morning calm drapes over the Mississippi River as clear skies stretch from the Gateway Arch to the Illinois bluffs. The air feels crisp but gentle — a reminder that autumn hasn’t fully given way to winter just yet. Sunshine and unseasonably warm air dominate through midweek before rain chances and a November cooldown slip into the region by late Thursday.
The National Weather Service in St. Louis reports a steady stretch of fair weather through Wednesday, with highs reaching the upper 60s to low 70s. Winds stay light and variable, and skies remain nearly cloudless — perfect for commuters, outdoor projects, or early holiday prep. Tuesday continues mild, topping near 70°F, while Wednesday warms to about 73°F, some 10 degrees above normal.
By Thursday afternoon, clouds begin to build ahead of a weak front sliding east across Missouri. A 30% chance of light rain could affect parts of the metro area, including I-70 and Route 40 commuters, though rainfall totals look light. Behind the front, temperatures fall modestly into the low 50s by Sunday, signaling the first cool push of November’s second week.
For now, residents can enjoy one of the region’s last stretches of true fall warmth. It’s ideal weather for raking leaves, finishing yardwork, or taking a stroll under clear skies — just keep an eye toward Thursday’s clouds as a reminder that winter’s transition is inching closer.
