    Areas affected...eastern Wy and the western NE Panhandle.

    Concerning...Tornado Watch 362...

    Valid 232359Z - 240130Z

    The severe weather threat for Tornado Watch 362 continues.

    SUMMARY...The risk for all hazards continues with severe storms
    across WW362.

    DISCUSSION...Across WW362, a few supercells have organized over the
    last couple of hours with reports of large hail and tornadoes. The
    severe risk will likely continue as these storms continue to track
    eastward within the broad upslope flow regime across eastern WY and
    the western NE Panhandle. Recent HRRR/RAP soundings show expanding
    low-level hodographs with time as the low-level jet is forecast to
    increase. A couple of tornadoes will remain possible with the more
    discrete supercells this evening as low-level shear increases and
    near favorable terrain influences.=20=20=20

    Upscale growth has been noted across northeastern WY with storms
    transitioning to a more linear mode with time. As storm outflows
    continue to merge, additional uspcale growth is expected to this
    evening as storm approach western SD. Damaging wind potential should
    increase accordingly with moderate buoyancy and deep-layer shear
    continuing to support storm organization.
