   Mesoscale Discussion 0662
   NWS Storm Prediction Center Norman OK
   1025 PM CDT Thu May 21 2020

   Areas affected...West-Central Texas

   Concerning...Severe Thunderstorm Watch 199...

   Valid 220325Z - 220500Z

   The severe weather threat for Severe Thunderstorm Watch 199

   SUMMARY...Severe threat may linger beyond 04z across portions of
   west-central TX. Hail remains the primary concern.

   DISCUSSION...Slow-moving supercells have progressed a few counties
   off the dry line, but have yet to show appreciable decrease in
   intensity despite boundary-layer decoupling. This may be partly due
   to better low-level moisture being drawn into these storms as LLJ
   strengthens across the High Plains. With 4-5 supercells likely still
   producing severe hail, there is some concern the severe threat will
   linger beyond the 04z watch expiration. While these storms should
   eventually weaken, consideration should be given to extending the
   watch in time for a few hours, possible a few counties east.
