    Areas affected...parts of the Texas Coastal Plain

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

    Valid 070035Z - 070230Z

    Probability of Watch Issuance...60 percent

    SUMMARY...Thunderstorms developing along a cold front/outflow
    boundary will likely pose a large hail threat across parts of the TX
    Coastal Plain for the next few hours. Watch issuance is probable
    based on recent convective trends.

    DISCUSSION...Regional radar mosaics and GOES IR imagery show
    multiple thunderstorms and convective towers developing along a
    southeastward moving cold front/outflow boundary along the TX
    Coastal Plain. The near-storm convective environment remains very
    favorable for organized convection with around 4000 J/kg MLCAPE and
    roughly 60 knots of effective bulk shear recently sampled by the 00
    UTC CRP sounding. This environment will support vigorous
    thunderstorm development along the boundary with primarily a large
    to very large hail threat (possibly upwards of 2.0 to 3.5 inches in
    diameter). Stronger capping with southwestward extend should limit
    storm coverage, but will also promote a higher probability for
    discrete, potentially long-lived convection. Given the recent radar
    trends of the developing cells (echo tops beginning to exceed 40-50
    kft), watch issuance appears probable.
