Areas affected...Carolina Piedmont vicinity

Concerning...Severe Thunderstorm Watch 317...321...322...

Valid 270027Z - 270200Z

The severe weather threat for Severe Thunderstorm Watch 317, 321,
322 continues.

SUMMARY...Some threat for damaging wind and hail will spread
east-southeast this evening. An isolated severe threat may
eventually spread east of the ongoing watches.

DISCUSSION...A couple of supercells are ongoing this evening across
parts of upstate SC, with golfball hail recently observed in the
Greenville-Spartanburg area. Some interaction between that supercell
and a left-moving cell to its west will be possible in the short
term, which could lead to a localized increase in damaging wind
potential. Discrete supercell activity is eventually expected to
weaken later this evening with the onset of nocturnal
cooling/stabilization, but some threat for hail and isolated
damaging wind will persist until the ongoing cells weaken. 

Farther north, some recent intensification has been noted with a
storm cluster moving southeastward across western NC, to the
northwest of Charlotte. The KCLT VWP depicts relatively weak
low-level flow, but rather strong deep-layer flow/shear, which in
combination with moderate buoyancy will support continued storm
organization in the short term this evening. While MLCINH will
gradually increase with time, a threat for damaging wind and perhaps
some hail will continue to spread east-southeastward. Depending on
the longevity of ongoing convection, local watch extension or
downstream watch issuance may eventually need to be considered.
