   Areas affected...Northwest Texas

   Concerning...Severe Thunderstorm Watch 380...

   Valid 231942Z - 232145Z

   The severe weather threat for Severe Thunderstorm Watch 380
   continues.

   SUMMARY...A cluster of severe thunderstorms will likely persist
   through late afternoon and early evening across parts of northwest
   Texas. Downstream watch issuance will be needed shortly.

   DISCUSSION...Latest radar imagery from KFDR and KLUB shows continue
   south/southeastward propagation of a cluster of strong/severe
   thunderstorms with a history of producing severe wind gusts.
   Although portions of this cluster are starting to become outflow
   dominant, additional development is noted on the west/southwest
   flank of the complex into a very unstable air mass. Given the
   persistence through late morning/early afternoon, probability seems
   high that the cluster will continue to pose a severe threat through
   the diurnal heating maximum when buoyancy will be maximized.
   Consequently, some severe wind and hail risk should continue
   downstream into the Rolling Plains of northwest Texas for the next
   several hours. Downstream watch issuance will be needed to address
   this concern.
