St. Louis, Mo. – A strong cold front sweeping into Missouri late Wednesday will deliver a sharp taste of fall, with temperatures expected to tumble well below seasonal norms. The coldest stretch is likely Thursday into Friday, when daytime highs will stall in the 60s and nighttime lows dip into the 40s across much of the state.
According to the National Weather Service in St. Louis, there is an 80 to 90 percent chance that temperatures will run below normal Thursday through Friday. Confidence is high in the cooler push, though forecasters caution that next weekend’s moderation is uncertain.
The change will be most noticeable in urban centers such as St. Louis and Columbia, where residents may need light jackets by Thursday evening football games and morning commutes. Rural areas of northern and eastern Missouri could see lows settle near 40, raising concerns for early-season impacts on outdoor events and late crops.
Rainfall is not expected with this system, meaning fields and roads will remain dry, but drivers should prepare for brisk mornings and cooler evenings. Officials encourage residents to plan for layered clothing, check heating systems, and take extra care with vulnerable populations unaccustomed to early-season chills.
Cooler-than-normal conditions are projected to dominate into Friday, with at least some moderation possible by next weekend.
