Locally damaging winds are possible. A watch is unlikely. DISCUSSION...Thunderstorms have begun to develop along an axis from northern AR into parts of KY/TN. This is along and south of a surface boundary, where temperatures have warmed into the upper 80-mid 90s. High PWAT values around 2 inches, MLCAPE over 1500 J/kg, and strong daytime heating suggest a few storms may occasionally produce gusty/damaging winds. Mid-level westerly flow of 25-30 knots may also encourage a few organized multicell clusters. Present indications are that the coverage of severe will be limited. ..Hart/Guyer.. 09/10/2026 ...Please see www.spc.noaa.gov for graphic product...
