    Concerning...Severe Thunderstorm Watch 182...

    Valid 292250Z - 300015Z

    The severe weather threat for Severe Thunderstorm Watch 182
    continues.

    SUMMARY...The severe risk (primarily for large hail) continues
    across WW182 this evening.

    DISCUSSION...A cluster of storms remains ongoing along the modified outflow/cold front in northern portions of WW182. So far, these
    storms have remained on the cool side of the slowly sagging boundary
    with little intensification noted. Still, some storm-scale rotation
    and presence of large MUCAPE (3000-4000 J/kg) amid favorable
    deep-layer shear for supercells will support severe potential,
    mainly in the form of large to very large hail. An uptick in severe
    potential could occur if these storms are able to move onto the warm
    side of the boundary. This would also support some risk for an
    isolated tornado and damaging gusts, but this remains uncertain.

    Additional development has been noted farther northwest along the
    boundary into Terrell and Crockett Counties. CAM guidance and
    observational trends suggest a similar severe risk is possible with
    these storms as they mature this evening. Given the extremely
    unstable and strongly sheared environment, the severe risk continues
    across WW182.
