    Mesoscale Discussion 1797

    Areas affected...portions of eastern VA and far northern NC

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

    Valid 022134Z - 022300Z

    Probability of Watch Issuance...20 percent

    SUMMARY...A cluster of strong to occasionally severe storms may pose
    a risk for isolated wind damage late this afternoon into the
    evening.

    DISCUSSION...Over the last couple of hours, scattered thunderstorms
    ongoing over the central Appalachians have gradually coalesced into
    a loosely organized cluster across parts of southern VA and far
    northern NC. The environment ahead of this cluster is very warm and
    unstable with temperatures in the 90s F and 3000+ J/kg of MLCAPE.
    However, very limited deep-layer shear is in place, with most VADs
    showing generally less than 20 kt. While modest in organization, the
    fairly pronounced cold pool moving into plentiful buoyancy should
    continue to support strong transient updrafts. The high PWAT air
    mass and pulse-like nature of the convection should also support
    occasional stronger downdrafts within the collapsing cores. Isolated
    damaging winds are possible along with a low-end risk of higher
    gusts to 50-60 mph. Displaced away from deeper forcing for ascent
    and flow aloft, storm organization will remain tied to the
    propagation along and ahead of the outflow. This should remain
    fairly limited in scope, and a WW is unlikely.
