SPC Maintains Multiple Severe Thunderstorm Watches as MCSs Push East‑Southeast

Overview

• Multiple Severe Thunderstorm Watches remained in effect Monday as the Storm Prediction Center tracked convective clusters and mesoscale convective systems across the central U.S.
• The primary hazards noted by SPC were damaging straight‑line wind gusts and large to very large hail, with discrete supercells earlier producing 1–2 inch hail reports near Emporia, KS.
• Storms evolved from semi‑discrete supercells into larger MCSs and developing MCVs, and that upscale growth shifted the main threat toward strong, damaging winds as systems propagated east‑southeast into southern Kansas and northern Oklahoma.
• SPC used mesoscale discussions to set watch‑issuance probabilities that varied by region—some areas had high probabilities (for example ~80% in parts of western/middle Tennessee and parts of the High Plains) while other areas were judged unlikely for new watches because nocturnal stabilization and weaker deep‑layer shear reduced confidence.
• Spotter and instrument reports included a brief tornado near Madison, KS and 1–2 inch hail near Emporia, KS, and SPC said coordination with local NWS offices and high‑resolution model guidance will determine whether watches are extended or new watches are issued into northwest Oklahoma, southwest/south‑central Kansas or downstream corridors.
