Severe Storms and Flash‑Flood Risk Persist Across Plains and Midwest
Forecasters warn slow‑moving, training storms over saturated ground are producing torrential rainfall rates that pose localized flash‑flood risk with intermittent damaging winds as the system shifts east.
Overview
- Weather Prediction Center discussions say storms are producing localized rain rates of 2 to 3 inches per hour and pockets of 3 to 5+ inches, a pattern likely to trigger flash flooding where soils are already wet.
- NWS Storm Prediction Center products show ongoing severe‑thunderstorm watches and high probabilities for new watches in the Northern Plains and parts of the Ohio Valley because of large hail and damaging straight‑line winds.
- Forecasters attribute the event to a closed upper low, a strengthening nocturnal low‑level jet and anomalously deep tropical moisture that favor backbuilding and training of storms.
- Antecedent rainfall left soils saturated with reported totals of 2–8 inches in some locations, lowering runoff thresholds and increasing flood risk for urban areas, small streams and sensitive basins.
- Officials expect a gradual eastward shift and overall weakening as daytime heating changes, but they urge people in northeastern Oklahoma, Missouri, eastern Kansas and the Red River/Arklatex corridor to follow local NWS offices and River Forecast Centers for watches and warnings.
