St. Louis, MO – The remnants of tropical cyclone Beryl are set to sweep across southeast Missouri tonight, bringing significant rainfall to the region. Flash flooding is the primary concern, with forecasts predicting 1 to 3 inches of rainfall, and localized areas potentially receiving higher amounts by 4 AM Wednesday.
According to the National Weather Service (NWS) in St. Louis, the heavy rain, combined with already saturated soils, is expected to cause rapid runoff into creeks, streams, and rivers, heightening the risk of flash flooding. Residents are urged to stay alert and have a reliable way to receive weather updates. Authorities emphasize the danger of driving through floodwaters, no matter the depth.
The hourly forecast for St. Louis indicates continuous rainfall throughout the day, with temperatures hovering around 69°F. Rain is expected to persist until the evening, tapering off by Wednesday. The flood warning remains in effect until early Saturday morning, while a flood watch is active until 4:00 AM Wednesday.
Looking ahead, the forecast shows a mix of weather patterns. Wednesday and Thursday are expected to be partly sunny with highs of 65°F and 67°F, respectively. By Friday, temperatures will rise to around 69°F with clear skies. The weekend will bring more sunshine, with highs of 72°F on Saturday and 75°F on Sunday. Early next week, the region will see a gradual warming trend, with temperatures reaching 98°F by Tuesday.
