    Areas affected...portions of southwestern and south-central Kansas

    Concerning...Tornado Watch 392...

    Valid 260020Z - 260145Z

    The severe weather threat for Tornado Watch 392 continues.

    SUMMARY...Additional thunderstorm development across portions of
    southwestern Kansas within Tornado Watch 392 may pose a risk for all
    severe hazards, with a conditional risk for a strong tornado or two.

    DISCUSSION...An isolated thunderstorm has developed southwest of
    Dodge City, KS, within a zone of enhanced low-level convergence
    along a surface stationary boundary and remnant outflow boundary.
    Uncertainty remains regarding whether this storm (and any additional development) will persist eastward owing to low-level inhibition
    north of the remnant outflow boundary (75-100 J/kg inhibition
    sampled for surface and mixed-layer parcels by the 00 UTC DDC
    observed sounding). For any persisting storm, strong effective shear
    will support supercells capable of large to very large hail given
    elongated hodographs and steep mid-level lapse rates (around 7.0-7.5
    C/km per latest objective analysis).=20=20

    Additionally, should storms persist farther east into south-central Kansas/north-central Oklahoma, a conditional tornado threat will
    exist. Enhanced low-level shear north of the outflow boundary (350+
    0-1 km SRH sampled by the ICT VWP) coupled with a strengthening
    southerly, low-level jet will promote a risk for tornadoes, some
    potentially strong, with any supercell that can become surface based
    (or where dynamical lifting within supercell mesocyclones can
    overcome modest low-level stability). This scenario remains
    uncertain at this time, however, due to the strength of inhibition
    across southern Kansas.
