    Areas affected...Eastern Colorado

    Concerning...Tornado Watch 191...

    Valid 200021Z - 200115Z

    The severe weather threat for Tornado Watch 191 continues.

    SUMMARY...Severe threat continues across Tornado Watch 0191. A
    Severe Thunderstorm Watch replacement may be necessary shortly.

    DISCUSSION...Earlier supercell storms have recently grown upscale in east-central Colorado, with weakening cells in northeastern Colorado
    and isolated multicells persisting in southeastern Colorado.

    Given widespread cold pool development and associated convective
    upscale growth, it appears the tornado threat has substantially
    decreased. Some severe potential may linger with any cells that are
    associated with a convectively uncontaminated airmass, particularly
    near the Colorado/Kansas border. As such, a replacement Severe
    Thunderstorm watch may be needed shortly, where large hail and
    isolated damaging wind gusts will be the main concerns.
