    Areas affected...Eastern TX Panhandle...Western North
    Texas...Western OK

    Concerning...Severe Thunderstorm Watch 121...

    Valid 252341Z - 260045Z

    The severe weather threat for Severe Thunderstorm Watch 121
    continues.

    SUMMARY...Threat for hail and strong wind gusts persists across
    Severe Thunderstorm Watch 121.

    DISCUSSION...One-minute GOES-16 visible imagery and recent surface
    observation reveal numerous surface boundaries across the eastern TX
    Panhandle and western north TX. The most well-defined boundary is
    the wavy dryline extending southwestward from a low near PPA. An
    outflow boundary extends from central TX northwestward into western
    north TX and perhaps far southwest OK. Ongoing storm near CDS may
    begin to interact with this outflow boundary soon. Some updraft
    intensification is possible with any initial interaction.
    Thereafter, continued forward propagation along the boundary is then
    possible. Some low-level stabilization has occurred downstream in
    western north TX and north-central TX so there is some question as
    to how long the ongoing storm complex will be able to maintain its
    current intensity.

    Farther north, several unsuccessful attempts at convective
    initiation were made across Hemphill county before the current storm
    over the county developed. Downstream airmass appears favorable for
    storm persistence, particularly if the storm progresses
    southeastward into the more buoyant air in western OK. More
    favorable low-level flow also exist across western OK where current
    surface observations show southeasterly winds around 15 kt. If this
    storm is able to maintain strength and track southeastward, all
    severe hazards, including a tornado, are possible. However, given
    the history of failed initiation in the area and modest convective
    inhibition still remaining, some uncertainty exists regarding
    whether or not the storm will be able to realize the favorable
    environment farther east.

    Areas affected...south through southeast Texas

    Concerning...Severe Thunderstorm Watch 128...

    Valid 040435Z - 040600Z

    The severe weather threat for Severe Thunderstorm Watch 128
    continues.

    SUMMARY...Line of storms will continue to pose a risk for isolated
    strong to locally damaging gusts next hour or two, mainly across a
    portion of south Texas toward the central Texas coast.

    DISCUSSION...A line of strong storms persists from a portion of
    south Texas near Cotulla to southeast Texas near Bryan. The southern
    portion of the line is more organized and moving south at 35+ kt and
    will continue to pose a risk for isolated damaging wind next couple
    hours. The severe threat with the portion of the line moving through
    southeast Texas appears more marginal. Houston VWP indicate
    low-level winds just above the surface have veered and weakened in
    wake of a leading shortwave trough moving through the lower MS
    Valley. However, the circulation with a secondary MCV near Bryan
    should help to sustain the northern portion of the line through
    southeast TX, but given the stabilizing boundary layer and weaker
    low-level winds in this region, confidence is not particularly high
    regarding potential for intensification.
