    Areas affected...Far eastern KY into WV...western/southern VA...NC

    Concerning...Severe potential...Watch unlikely=20

    Valid 272050Z - 272245Z

    Probability of Watch Issuance...20 percent

    SUMMARY...Isolated damaging winds are possible into early evening.

    DISCUSSION...Storms have increased in coverage and intensity over
    the last hour across parts of NC, and also from eastern KY into WV.
    Deep-layer shear is weak across the region, but buoyancy is strong,
    with MLCAPE of 2000-3000 J/kg along the western/southern periphery
    of an extensive cloud shield over the Mid Atlantic.=20

    Relatively large PW and steep low-level lapse rates will support a
    risk of localized downbursts with the strongest storms. Some outflow consolidation is possible with time, if a sufficient concentration
    of storms can develop. This could lead to a somewhat greater chance
    for damaging wind, though this scenario remains uncertain.
