Areas affected...much of WV

Concerning...Severe potential...Watch unlikely

Valid 211503Z - 211600Z

Probability of Watch Issuance...5 percent

SUMMARY...Isolated strong/near severe wind gusts will be possible
with a southeastward-moving complex of thunderstorms.  A watch is
not anticipated.

DISCUSSION...A complex of thunderstorms, with origins over eastern
Iowa Thursday evening, was moving southeast at around 30 kts over
southern/southeast Ohio and entering western portions of West
Virginia at 1500Z.  Downstream, filtered diurnal heating will
maintain a corridor of moderate surface-based buoyancy.  Weak
deep-layer shear should limit the longevity of this convective
system in agreement with latest high-resolution guidance, however in
the short term at least some potential will exist for isolated
strong/near severe gusts over the next couple of hours.  The overall
severe risk should remain isolated and a watch is not anticipated.
