St. Louis — The St. Louis metro area is heading into a highly variable weather pattern to close out the workweek and begin the weekend, according to the National Weather Service in St. Louis. Residents can expect breezy and mild conditions Friday, followed by a sharp temperature drop Saturday, and then a significant warm-up by Sunday.
Friday will feature decreasing cloud cover and breezy conditions, with afternoon highs ranging from the 40s to the low and mid-50s. Winds may be noticeable at times, especially along exposed stretches of Interstates 70, 64, 44, and 55, but no major travel disruptions are expected during the day.
A strong cold front will move through the region late Friday night into early Saturday, ushering in much colder air. Saturday will feel dramatically different, with mostly sunny skies but highs only in the 30s to low 40s. The colder temperatures will be most noticeable during the morning and early afternoon, particularly for anyone traveling or working outdoors.
By Sunday, the pattern flips once again. Temperatures are expected to rebound 15 to 20 degrees, with highs climbing into the mid-40s across Illinois and near 60 degrees in parts of central and southeast Missouri. Clouds will gradually decrease through the day, allowing for a noticeably milder afternoon.
Drivers should remain alert for rapid changes in temperature, which can affect road conditions overnight and during early morning hours. While no winter precipitation is expected, fluctuating temperatures can still impact travel comfort and planning.
Overall, the weekend will feature fast-changing conditions, making it important for residents across the St. Louis region to stay informed and prepared for both winter-like cold and spring-like warmth within a 48-hour span.
