St. Louis, MO – Halloween night across Missouri will bring cool and breezy conditions, with temperatures dipping into the 40s by late evening, according to the National Weather Service in St. Louis.
Forecasters say Friday evening temperatures will start in the upper 50s to near 60°F around 3 p.m. before gradually falling into the mid to upper 40s by 10 p.m. Winds will range from 15 to 20 mph early in the evening, slowly easing as the night goes on but remaining brisk enough to add a noticeable chill.
According to the National Weather Service, the coolest conditions will arrive in northern and central parts of the state, including Columbia and Quincy, where late-night readings could touch the lower 40s. Areas farther south, such as Farmington and Salem, will stay slightly milder but still cool enough to warrant a jacket for trick-or-treaters.
The evening will stay dry, offering good conditions for Halloween events despite the brisk breeze. Residents are encouraged to bundle up children and plan for temperatures to feel a few degrees cooler due to the wind.
