    Areas affected...Parts of central/eastern ND

    Concerning...Severe Thunderstorm Watch 476...

    Valid 100023Z - 100200Z

    The severe weather threat for Severe Thunderstorm Watch 476
    continues.

    SUMMARY...A threat for isolated large hail will continue into the
    evening, along with some increase in severe-wind potential. A
    tornado or two is also possible.

    DISCUSSION...A few semi-discrete supercells are moving southeastward
    across central/northeast ND early this evening. MLCAPE of 2500-3500
    J/kg and moderate deep-layer shear will continue to support
    supercells through the early evening, with large to locally very
    large hail possible. Some southeastward acceleration has recently
    been noted with this supercell cluster, which may be indicative of
    an expanding cold pool. Any further upscale growth could result in
    an increasing severe-wind threat as storms spread southeastward.
    Also, while low-level flow is not particularly strong, modest
    low-level veering (as noted in the KBIS VWP) and presence of
    sustained supercell structures could also support potential for a
    tornado or two.
