   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.
