MISSOURI – Storms are on the move toward the St. Louis metro, setting up a wet and windy Saturday before sunshine makes a fast return by Sunday. The National Weather Service in St. Louis warns that showers and thunderstorms will develop late Friday night and continue through much of Saturday, especially along the I-70 and I-55 corridors across eastern Missouri and southwest Illinois.
The heaviest rain is expected between 6 a.m. and 2 p.m. Saturday, with locally gusty winds and brief downpours possible. Drivers and tailgaters heading to weekend events should plan for slick roads and reduced visibility. Rain chances sit near 90%, tapering off by Saturday night as cooler, drier air filters in from the northwest.
By Sunday, skies clear across the region with temperatures near 66°F, delivering a crisp, sun-filled day perfect for fall leaf-viewing drives, pumpkin patches, or outdoor festivals. The calm pattern extends into early next week, with sunny skies and mild highs in the low 70s Monday and Tuesday.
Looking ahead, no major weather systems are expected through midweek, giving the region a much-needed break from the weekend’s unsettled conditions.
After Saturday’s stormy start, St. Louis and the Metro East can look forward to a stretch of ideal fall weather — a classic October reset for outdoor plans.
