   Areas affected...Southwestern into South Central Kansas.

   Concerning...Severe Thunderstorm Watch 174...

   Valid 122347Z - 130115Z

   The severe weather threat for Severe Thunderstorm Watch 174
   continues.

   SUMMARY...Storms forming north of the supercell in Clark County, KS
   should congeal into one or two supercells this evening. These storms
   will pose a risk for large hail and damaging winds, but are expected
   to wane after dark which will likely preclude the need for a severe
   thunderstorm watch north of watch 174.

   DISCUSSION...In addition to the persistent supercell along the
   Oklahoma/Kansas border and a cluster of supercells northeast of
   Amarillo, storms are starting to form further north along the
   stationary front in Kansas. Given the very unstable environment and
   effective shear around 35 to 40 knots, expect the developing cells
   in Kansas to organize into one or two dominant supercells with large
   hail and damaging winds as the primary risk. This new development
   will likely wane shortly after sunset with the better organization
   relegated to areas further south within WW 174 where storms are more
   likely to congeal and the threat may persist into the early
   overnight hours. Given the short duration of the threat, a severe
   thunderstorm watch is not expected for areas north of Severe
   Thunderstorm Watch 174.
