Areas affected...Southeast OH...Central/western WV

Concerning...Severe Thunderstorm Watch 432...

Valid 222337Z - 230100Z

The severe weather threat for Severe Thunderstorm Watch 432
continues.

SUMMARY...The threat for locally damaging winds and perhaps a brief
tornado continues across valid portions of WW 432.

DISCUSSION...Several clusters of convection are ongoing across WW
432. To the east, a small bowing segment has developed west of
Elkins, WV and may pose a somewhat greater threat for damaging wind
in the short term along its path. Further west, convection has
largely remained semi-discrete thus far. With sufficient buoyancy
and moderate west-northwesterly flow of 30-40 kt just above the
surface across this region, the strongest cells will continue to
pose a threat of localized damaging wind and perhaps marginally
severe hail. A brief tornado also cannot be ruled out with any
stronger discrete cell traversing the effective outflow boundary.
Some potential exists for additional small bowing segments to
develop later this evening, which would pose a somewhat more
concentrated damaging wind risk along their path.
