   Areas affected...south central Nebraska/western Kansas and vicinity

   Concerning...Severe Thunderstorm Watch 360...

   Valid 212334Z - 220130Z

   The severe weather threat for Severe Thunderstorm Watch 360

   SUMMARY...Scattered to isolated thunderstorms continue across parts
   of the watch area, where local risk for hail and damaging wind gusts

   DISCUSSION...Latest radar loop shows isolated thunderstorms ongoing
   across south central Nebraska, and then more numerous storms
   concentrated over southwest Kansas and vicinity.  The storms are
   ongoing near/ahead of a north-south surface trough, within an axis
   of moderate instability (mixed-layer CAPE average 2000 to 3000 J/kg
   per objective analysis).  While flow aloft -- and thus deep-layer
   shear -- remains on the marginal side for well-organized updrafts
   (and hence the rather transient nature of the stronger cores),
   potential for locally damaging winds and hail will continue over the
   next couple of hours with a few of the strongest storms.
