    Areas affected...portions of western south Carolina and eastern
    Georgia

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

    Valid 291909Z - 292145Z

    Probability of Watch Issuance...5 percent

    SUMMARY...A few damaging gusts possible across portions of western
    South Carolina and eastern Georgia. A watch is not anticipated at
    this time.

    DISCUSSION...Convection is developing near the Georgia/South
    Carolina border at the periphery of an upper-level ridge. A deep,
    moist air mass is in place with weak flow throughout the column, as
    shown by the JAX 18Z RAOB. The weak flow is giving rise to mainly
    single-cell convection with occasional multicells, and a few weak
    downburst signatures have been observed on regional WSR-88Ds. Due to
    the moist profiles, some damaging gusts may occur with water-loaded
    downdrafts, and any clustering may increase the potential for
    damaging gusts. Additionally, a weak surface boundary may provide a
    focus for additional convection as the afternoon progresses.
    However, the coverage of damaging gusts is expected to be sparse
    enough that a watch is not anticipated at this time.
