St. Louis, Missouri – Isolated thunderstorms could disrupt weekend plans across central and northeast Missouri and west-central Illinois, with higher storm chances building by Sunday afternoon.
According to the National Weather Service in St. Louis, a 20–40% chance of storms is expected late Saturday into overnight hours, primarily in cities like Columbia, Hannibal, and Quincy. On Sunday, storm chances rise area-wide to 30–50%, particularly in the afternoon. A few of these storms may bring strong winds and locally heavy rainfall, although widespread hazards are not expected.
Temperatures Saturday will push into the low to mid-90s across the region, with slightly cooler highs between 84° and 92° on Sunday. Most areas will still see stretches of dry time between showers. Outdoor plans early in the day may be unaffected, but late-day events could face interruptions.
Residents are advised to monitor weather updates and secure loose outdoor items. If thunder roars, head indoors to stay safe. Expect these daily afternoon storm chances to persist through the week.
