Overview
- SPC forecasters, who maintained Tornado and Severe Thunderstorm Watches Monday, say the risk for strong tornadoes remains focused on southern Illinois, southeast Missouri and western Kentucky.
- Late Monday, mesoscale analyses showed very high energy in the air (MLCAPE near 1500–3000 J/kg) with a 50–60 kt low‑level jet a few thousand feet up, creating large, curved wind profiles that favor supercells capable of tornadoes.
- As storms consolidated into clusters and lines, forecasters noted a shift toward widespread damaging winds while cautioning that embedded supercells could still produce tornadoes even as the very large hail threat eased.
- Tornado Watches 162 and 166 cover the evolving corridor from northern Arkansas into the lower Ohio Valley, and media reports estimate more than 60 million people lie within the broader severe‑weather zone from the Upper Midwest to the South.
- This round follows earlier outbreak days that brought destructive hail, wind damage and a confirmed EF‑4 in Enid, Oklahoma, along with reported tornado deaths in North Texas, raising the stakes for communities now under fresh watches and warnings.
