   Areas affected...Northwest Kansas and eastern Colorado

   Concerning...Severe Thunderstorm Watch 444...

   Valid 162347Z - 170115Z

   The severe weather threat for Severe Thunderstorm Watch 444
   continues.

   SUMMARY...The severe weather threat continues for a few more hours
   in northwest Kansas.

   DISCUSSION...A line of storms stretching from Yuma county, Colorado
   to Sheridan County Kansas has produced several strong to severe wind
   gusts and near severe hail over the past several hours. There is
   considerable uncertainty how this activity will evolve over the next
   few hours. Outflow has now moved close to 10 miles ahead of this
   line and it is moving toward an area which has been convectively
   cooled from earlier storms. However, the outflow has been well ahead
   of this activity for the last hour and it has been able to sustain
   itself and move southward with the outflow producing strong to
   severe winds. Additionally, this outflow boundary will collide with
   the outflow boundary from earlier storms to the south within the
   hour which may lead to an increase in new convection in this region.
   The environment remains very favorable for strong to severe winds
   with DCAPE around 1600 J/kg. Therefore, expect this line of storms
   to continue southward for at least a few more hours with a threat
   for mostly damaging winds.
