St. Louis, MO – Under a clear sky and calm breeze, St. Louis wakes to another crisp, quiet fall morning. The Gateway Arch glows faintly in the early light, while temperatures sit in the low 40s — cool enough to see your breath but pleasant enough for an early walk.
The next several days stay dry and tranquil as a broad ridge of high pressure stretches over the Midwest. Sunshine dominates today and Friday, with highs near 60°F to 62°F. Northwest winds will stay light, occasionally gusting near 20 mph by afternoon, keeping the air crisp and visibility clear.
By Saturday morning, temperatures fall into the upper 30s, and patchy frost could develop in outlying suburbs west of I-55 and across rural Illinois counties. Afternoon highs rebound only into the mid-50s — the coolest stretch so far this week.
Sunday turns slightly warmer and mostly sunny, with highs near 60°F and a light southwest breeze. The calm, mild pattern continues into early next week, though long-range models are hinting at a colder push around mid-November, which could bring the region’s first legitimate snow chance north of I-70 if current trends hold.
For now, the Halloween weekend stays quiet — ideal for outdoor events, last-minute leaf cleanup, or fall decorating before the chillier air settles in next week.
