St. Louis, Missouri – Clouds will hang over Missouri throughout Memorial Day, with light rain chances gradually increasing into the evening, potentially dampening outdoor celebrations. Highs are expected to hover in the mid-60s to low 70s, offering cooler-than-average conditions for late May.
According to the National Weather Service in St. Louis, the region will stay mostly cloudy all day Monday, with drizzle or light showers more likely after midday. No severe weather is anticipated, but residents should plan for damp and cool conditions, especially for outdoor gatherings, parades, or cemetery visits.
In St. Louis, Columbia, and Jefferson City, residents may see brief periods of sprinkles between 2 and 6 p.m., though accumulations are expected to be light.
