    Areas affected...Southeast Colorado...southwest Kansas...and the
    OK/TX Panhandles

    Concerning...Severe Thunderstorm Watch 181...

    Valid 180228Z - 180430Z

    The severe weather threat for Severe Thunderstorm Watch 181
    continues.

    SUMMARY...The severe wind and hail potential will continue across
    the TX and OK Panhandles for the next 1-2 hours, but a gradual
    weakening trend is expected across WW 181.

    DISCUSSION...A line of storms continues to propagate east/northeast
    across southeast CO into southwest KS and across the OK/TX
    Panhandles. This line has produced a handful of measured severe wind
    gusts in the past hour, and MRMS vertically integrated ice trends
    show a few stronger updrafts capable of severe hail in the near
    term. However, composite reflectivity and lightning trends over the
    past hour have shown a gradual weakening of the line as it moves
    across southeast CO where deep-layer shear and MLCAPE are
    diminishing. While sporadic damaging winds and isolated hail remain
    possible in the near term, this weakening trend should continue.=20

    Further to the south across the OK/TX Panhandles, instability and
    deep-layer shear remain favorable for maintaining the evolving QLCS
    for the next 1-2 hours. Increasing inhibition and waning instability
    will likely lead to a gradual weakening trend as the line approaches
    western OK, but severe wind and a few instances of severe hail
    remain likely in the near term. Trends will continue to be
    monitored, but a downstream watch is currently not anticipated.
