    Areas affected...Parts of south-central Kansas into northwest
    Oklahoma

    Concerning...Severe Thunderstorm Watch 506...

    Valid 172319Z - 180045Z

    The severe weather threat for Severe Thunderstorm Watch 506
    continues.

    SUMMARY...Large to very large hail and significant severe gusts will
    remain possible with an intense supercell in south-central Kansas.
    Convective trends suggest this storm will impact parts of northwest
    Oklahoma within the next few hours.

    DISCUSSION...An intense supercell continues east-southeast of Dodge
    City. Hail of 2.5-3 inches has recently been reported with this
    storm. Given the strength of the mesocyclone/rear-flank downdraft on
    KDDC velocity data, significant severe wind gusts are also possible.
    Radar imagery over the last hour has generally suggested that the
    rear-flank gust front has remained out ahead of this storm. There
    are surface southeasterly winds on the eastern flank of this storm
    per ASOS/OK Mesonet data. Should this storm be able to pull this
    boundary in, a tornado would be possible. Similar to yesterday,
    there is some dryness in the low levels noted on short-term forecast
    soundings. Convection along the rear-flank gust front has been
    developing periodically with this storm and has merged into the main
    updraft. This storm will likely maintain intensity as long as this
    process continues and the impacts of entrainment can be minimized.
    Given current surface observations and objective mesoanalysis this
    storm is likely to move south or perhaps just west of south. While
    MLCIN is present, it is not overly prohibitive, and there is some
    potential for this mature storm to move into the far eastern OK/TX
    Panhandles. Trends will be monitored. Development farther east of
    this storm is not certain given the effects of anvil cloud cover and
    otherwise nebulous convergence in the surface wind field.
