    Areas affected...portions of northwestern Kansas into central
    Nebraska

    Concerning...Severe Thunderstorm Watch 612...

    Valid 170144Z - 170315Z

    The severe weather threat for Severe Thunderstorm Watch 612
    continues.

    SUMMARY...Some severe threat will persist for a few more hours, with
    severe gusts/hail the main threats.

    DISCUSSION...Currently, two general areas of convection continue to
    show severe potential. Firstly, a line of thunderstorms has quickly
    intensified across extreme northwestern KS, along the NE border, in
    association with several cold pool and convective outflow boundary
    mergers. These storms will continue to propagate east-southeastward
    amid a buoyant airmass characterized by 1500 J/kg MLCAPE. In central
    NE, an embedded bowing structure has produced some measured 50+ kt
    gusts, and this potential may continue for the next hour or so as
    well. However, waning buoyancy and increasing MLCINH amid
    boundary-layer decoupling should gradually reduce severe potential
    over the next few hours.
