    Areas affected...portions of the Texas Big Bend into Stockton
    Plateau

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

    Valid 032201Z - 040000Z

    Probability of Watch Issuance...20 percent

    SUMMARY...Isolated supercells forming along a dryline across the
    Texas Big Bend Region into Stockton Plateau will pose a risk of
    large/very large hail and severe wind gusts over the next couple of
    hours.

    DISCUSSION...Thunderstorm development is ongoing south of Fort
    Stockton along a trailing dryline. A moderately unstable environment
    (2000-2500 J/kg MLCAPE) and around 40-50 kts of effective bulk shear
    will favor supercell development capable of large/very large hail
    and severe wind gusts. While mid-level lapse rates remain modest (~7
    C/km), ample buoyancy within the hail growth zone (300-400 J/kg)
    coupled with straight, elongated hodographs will support the
    potential for hail of 2+ inches in diameter with any persistent
    supercell. Given the displacement of better synoptic-scale forcing
    well to the north, storm coverage is expected to remain isolated.
    Thus, watch issuance appears unlikely at this time. A new Severe
    Thunderstorm Watch may need to be considered, however, should
    supercells trend towards more scattered coverage with the potential
    for a longer duration hail threat.
