SUMMARY...Thunderstorms will continue to pose a risk for a few
strong to damaging gusts through about 00Z, followed by an overall
decrease in intensities. Due to the limited duration of remaining
threat, a WW will probably not be necessary.
DISCUSSION...Widely scattered to scattered thunderstorms continue
developing in the pre-frontal warm sector across eastern TN where
the atmosphere remains moderately unstable with up to 2000 J/kg
MLCAPE. Latest VAD wind profile from Morristown shows unidirectional
west southwest winds from 30-40 kt in the 2 - 6 km layer but with
weak vertical shear. This environment is supportive of multicells
capable of producing locally strong to damaging gusts. The primary
threat should persist another couple of hours, but storms should
begin a weakening trend after 00Z as the boundary layer stabilizes
with loss of diurnal heating.
