Flash Flooding and Severe Storms Threaten Large Parts of Texas

Overview

• National Weather Service centers have issued multiple mesoscale discussions and active severe‑storm watches as storm complexes move across Texas, with forecasters warning flash flooding is likely in central, south‑central and North Texas.
• Heavy bands are producing extreme rates of rain where they train over the same area, with operational analyses showing 1–3 inches per hour and regional guidance projecting 3–5 inch totals and isolated spots above 6 inches in the worst cells.
• A squall line and organized MCSs are carrying a concurrent severe threat for damaging straight‑line winds, large hail and isolated tornadoes, and forecasters say embedded bowing segments have prompted continuation of Severe Thunderstorm Watches.
• The greatest near‑term danger is urban and small‑basin flash flooding in populated corridors such as the Dallas–Fort Worth metro, the I‑35/I‑10 corridors and portions of the Rio Grande Valley, where recent rain has already left soils saturated.
• Forecasts cite a closed low, strong low‑level jets and high precipitable water values as the drivers that favor long residence time for heavy rain, and officials urge residents to monitor local warnings, avoid flooded roads and expect rapidly changing conditions.
