    Areas affected...Central into southwest Kansas

    Concerning...Severe potential...Watch unlikely=20

    Valid 082149Z - 082345Z

    Probability of Watch Issuance...5 percent

    SUMMARY...Thunderstorms developing along a cold front may pose a
    risk of strong to severe downburst winds, and perhaps large hail,
    through mid to late evening. Watch issuance is not expected.

    DISCUSSION...Latest radar and GOES IR cloud-top-temperature trends
    depict several intensifying thunderstorms developing across central
    KS along a cold front. With surface dewpoints in the upper 30s and
    low 40s and temperatures in the upper 70s, the thermodynamic
    environment is very well-mixed with surface-based LCLs estimated to
    be at around 2.5 km AGL, and MLCAPE values estimated to be between
    250 to 800 J/kg per recent forecast soundings and by modifying the
    18 UTC DDC RAOB to regional conditions. However, effective bulk
    shear are estimated to be at around 25 knots per regional VWPs and
    RAP analyses. This may be sufficient for transient organization of
    developing convection over the next few hours, especially if
    clustering can occur along the front, including southwest of ongoing thunderstorms to the north of the Dodge City, KS area where
    low-level convergence appears to be weaker, but MLCAPE may be
    slightly higher and could support a strong storm or two.

    Given the deeply mixed boundary layer, the predominant hazard will
    likely be strong to severe downburst winds within the deeper/more
    robust convection (though instances of severe hail appear possible
    given marginal, but sufficient, deep-layer wind shear). Although
    latest high-res guidance has struggled to capture the onset of this
    activity (per recent HRRR runs), most solutions suggest any severe
    risk will remain fairly localized to central to southwest KS and
    should only persist through mid/late evening.
