    Mesoscale Discussion 1683

    0441 PM CDT Fri Jul 19 2024

    Areas affected...Central/Southern High Plains

    Concerning...Severe potential...Watch likely=20

    Valid 192141Z - 192245Z

    Probability of Watch Issuance...80 percent

    SUMMARY...New Severe Thunderstorm Watch appears warranted for
    portions of the central/southern High Plains.

    DISCUSSION...Weak short-wave trough is evident within water-vapor
    imagery digging south-southeast across the central Plains. Scattered
    convection now reflects the leading edge of this feature, with
    thunderstorms gradually increasing across the central portions of
    ww555 from northwestern KS into eastern CO. This activity should
    propagate south along the primary corridor of instability (MLCAPE on
    the order of 2000 J/kg) toward the OK Panhandle later this evening.
    While LLJ is not forecast to be that strong, 25kt southerly jet
    should aid in the longevity of this activity as it spreads south
    across the High Plains. Damaging winds are the main risk, though
    some hail is possible.
