Areas affected...Southwest/southern middle TN into northern AL and
far northeast MS

Concerning...Severe Thunderstorm Watch 517...

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.
