Missouri Storm System Expected to Bring Severe Weather and Flood Risks Sunday

Forecasters expect a storm system to move across central Missouri on Sunday, June 20, 2026, bringing widespread showers, isolated thunderstorms, and the possibility of an isolated tornado, large hail and damaging winds.

In Columbia, high humidity will make temperatures feel near 90 °F as storms intensify from scattered morning showers to heavier rain in the afternoon, raising concerns about localized flooding on already saturated ground (8.35 inches of rain recorded in May 2026). Residents have been urged to stay weather‑aware.

In the Cape Girardeau area, a slight risk of severe weather is forecast for the afternoon, evening and overnight, with chances of strong winds, hail and isolated tornadoes. Temperatures are expected in the upper 80s to low 90s, and people are advised to have multiple alert methods and keep outdoor plans early Sunday.
