   Areas affected...southeast Colorado through southwest Kansas

   Concerning...Tornado Watch 175...

   Valid 152317Z - 160015Z

   The severe weather threat for Tornado Watch 175 continues.

   SUMMARY...A relatively small window will exist through mid evening
   for brief isolated tornadoes from a portion of southeast Colorado
   through southwest Kansas.

   DISCUSSION...Early this evening a stationary boundary extends
   through southwest Kansas into southeast Colorado. Dewpoints are
   generally in the upper 50s to around 60 F in vicinity of this
   boundary contributing to somewhat lower LCLs and up to 2000 J/kg
   MLCAPE. Storms will continue spreading eastward off the higher
   terrain, and other storms may initiate on the boundary. Effective
   bulk shear around 35 kt will promote both multicell and marginal
   supercell structures, and some increase in 0-2 km hodograph size
   will occur as the low-level jet strengthens this evening. The
   primary threat for a few brief tornadoes is expected to occur as
   storms develop along or move east and interact with the boundary
   where low-level vorticity will be maximized.
