   Concerning...Severe Thunderstorm Watch 217...

   Valid 242025Z - 242200Z

   The severe weather threat for Severe Thunderstorm Watch 217
   continues.

   SUMMARY...The damaging wind and large hail threat continues across
   watch 217.

   DISCUSSION...A cluster of storms has developed north of an MCV
   located west of Topeka at 20Z. The widespread storm coverage and
   subsequent storm interference has limited the intensity of this
   convection thus far. The exception is the far eastern cell in this
   line which has produced golf ball to baseball sized hail. This will
   continue to be the area with the greatest threat for very large hail
   given the unimpeded storm inflow. Despite the lack of more intense
   storms farther west, these storms still pose a severe threat as the
   downstream airmass features 1500 to 2500 J/kg MLCAPE and effective
   shear remains around 40 knots per EAX VWP. In addition, surface flow
   remains backed ahead of this convection and thus a tornado or two
   cannot be ruled out.
