Life‑Threatening Flash Flood Threat and Severe Storm Watch for Ozark Plateau

Overview

• Forecasters say a life‑threatening flash flood event is developing across the Ozark Plateau on Monday morning as slow‑moving storms train over rugged terrain.
• The Weather Prediction Center warned of extreme rainfall rates commonly 2–3+ inches per hour and isolated 4–6+ inch totals that could reach Flash Flood Emergency levels.
• The Storm Prediction Center has issued Severe Thunderstorm Watch 286 for the same region and notes isolated damaging wind gusts, some large hail, and a conditional tornado threat.
• A strengthening low‑level jet is transporting very moist air (precipitable water near 1.7–1.9 inches) and high instability (MLCAPE up to 2000–3000 J/kg), which supports intense, slow storms.
• Forecast uncertainty hinges on whether cold pools and mesoscale clustering force a southward moving MCS or allow persistent backbuilding, which will determine which communities receive the worst flooding or severe winds.
