   Areas affected...southeast Colorado through southwest Kansas

   Concerning...Tornado Watch 175...

   Valid 160154Z - 160300Z

   The severe weather threat for Tornado Watch 175 continues.

   SUMMARY...Isolated large hail, downburst winds and a brief tornado
   remain possible across southeast Colorado through southwest Kansas,
   but a gradual weakening trend is expected to commence, especially
   after 03Z.

   DISCUSSION...Small storm clusters continue moving slowly northeast
   through southeast CO and near the southeast CO/KS border. Some
   rotation was previously observed with storms that interacted with
   the stationary boundary across southeast CO where a tornado was
   reported. A brief tornado remains possible next hour or so, but
   primary threat appears to be isolated large hail and downburst
   winds. A strengthening low-level jet might maintain a small storm
   cluster or two into southwest KS this evening. However, weak flow
   aloft and increasing convective inhibition associated with the onset
   of nocturnal cooling suggest the severe threat should begin to wane
   by 04Z.
