Valid 270406Z - 270530Z The severe weather threat for Severe Thunderstorm Watch 517 continues. SUMMARY...Isolated damaging wind will remain possible into the early morning hours. DISCUSSION...A long-lived storm cluster continues to move southward across parts of western/middle TN late this evening. Some weakening has been noted over the last 1-2 hours, and a gradual weakening trend is expected to continue, due to weak low-level flow and weaker deep-layer flow/shear with southward extent. However, very rich low-level moisture continues to support strong to extreme buoyancy, with downstream MLCAPE in the 3000-4000 J/kg range. This buoyancy may aid in occasional updraft intensification along the gust front, and a continuation of at least an isolated damaging-wind threat into the early overnight hours across northern AL and far northeast MS. ..Dean.. 07/27/2026 ...Please see www.spc.noaa.gov for graphic product...
