St. Louis, Missouri – Colder air is set to tighten its grip on the St. Louis region as a series of cold fronts push temperatures steadily lower through the end of the week, culminating in daytime highs that fail to reach freezing by the weekend.
According to the National Weather Service in St. Louis, temperatures will drop in stages as multiple fronts move through the area. After highs reach the lower 50s early today, readings fall into the 40s Wednesday, then into the 30s by Thursday and Friday. By Saturday and Sunday, daytime highs are expected to remain in the 20s, marking a significant shift from recent mild conditions.
Overnight lows will fall even further, dipping into the teens by late week and potentially nearing the lower teens over the weekend. While widespread snow is not the primary concern at this time, the prolonged cold increases the risk for icy patches on untreated roads, especially during the overnight and early morning hours.
The cold will be accompanied by periods of breezy conditions, which will drive wind chills into the teens and single digits at times, particularly during the morning hours. These conditions can pose a risk to anyone spending extended time outdoors without proper protection.
City services and emergency managers urge residents to prepare now by checking home heating systems, protecting exposed pipes, and ensuring pets have warm shelter. Drivers should remain cautious on bridges and overpasses, where ice can form quickly as temperatures drop.
The cold pattern is expected to persist through the weekend, with only modest moderation early next week. Forecasters note additional cold weather advisories may be issued if wind chills trend lower. Residents are encouraged to stay informed as conditions continue to evolve across the St. Louis metro area.
