    Areas affected...Central Georgia into central South Carolina

    Concerning...Severe potential...Watch possible=20

    Valid 071959Z - 072200Z

    Probability of Watch Issuance...60 percent

    SUMMARY...Storms are initially developing within strongly buoyant
    airmass in Georgia and South Carolina. A greater organized wind
    damage threat will exist as a line of storms approaches from the
    west. A watch is possible for parts of Georgia into the central
    South Carolina.

    DISCUSSION...Strong buoyancy (4000+ J/kg MLCAPE) has developed in
    parts of Georgia into South Carolina as temperatures have risen into
    the mid/upper 90s F. With convective temperatures being breached, a
    few storms have developed in central Georgia. This environment,
    however, is currently weakly sheared and lacks large-scale ascent.
    Farther to the north and west, a more organized line of storms
    continues to east-southeast. Initial strong to near-severe
    convection is possible in the buoyancy axis with some potential for
    strong downdrafts. The potential for severe/damaging wind gusts will
    increase in association with the organized convective line later
    this afternoon into early evening. Both large-scale ascent and
    deep-layer shear should increase along with low-level winds as the
    main synoptic trough sags slightly southward. A watch is possible
    for parts of these areas this afternoon.
