    Areas affected...South Central Texas

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

    Valid 072102Z - 072230Z

    Probability of Watch Issuance...40 percent

    SUMMARY...Severe thunderstorm coverage is expected to increase
    across portions of south-central Texas this afternoon into the early
    evening. Damaging winds and large hail are the primary concerns,
    particularly with an ongoing cell in far southwestern Texas.

    DISCUSSION...As a southward-moving, convectively-modified cold front
    moves across portions of central and southwestern Texas, severe
    storm activity is expected to increase in the short term --
    particularly with a supercell tracking eastward from Uvalde. MUCAPE
    of 2000-3000 J/kg and effective shear of 35-40 kts will support
    continued convective development and organization along the modified
    cold front/outflow boundary. The primary threat will be for damaging
    winds and large hail, with storms continuing to pose such a threat
    even after being undercut by the cold front/outflow boundary. A
    severe thunderstorm watch may be needed in the next hour or two.
