    northeast Texas Panhandle

    Concerning...Severe Thunderstorm Watch 193...194...

    Valid 200441Z - 200645Z

    The severe weather threat for Severe Thunderstorm Watch 193, 194
    continues.

    SUMMARY...Severe threat continues across Severe Thunderstorm Watches
    0193 and 0194, but a slow downward trend in convective intensity is
    expected during the overnight hours.

    DISCUSSION...An organized MCS is propagating southeast across Severe Thunderstorm Watches 0193 and 0194, with severe wind gusts over 60
    knots observed within the strongest portion of the line from Gray to
    Pawnee Counties within the last hour. Gusts up to 65 knots were also
    recently observed in Seward County, Kansas.

    With a strong surge of the cold pool in progress, along with
    adequate effective bulk shear oriented normal to the MCS leading
    line, a few more instances of damaging wind gusts are possible
    within the next few hours. Still, recent RAP point forecast
    soundings indicate a stabilizing boundary layer, and a downward
    trend in intense cores along the leading line of the MCS were noted
    near DDC in the latest few radar scans. As such, a slow downward
    trend in severity is likely as the MCS slowly weakens throughout the
    evening.
