   Mesoscale Discussion 0755
   NWS Storm Prediction Center Norman OK
   1007 PM CDT Fri May 13 2022

   Areas affected...far southern Kansas into northern Oklahoma.

   Concerning...Severe Thunderstorm Watch 214...

   Valid 140307Z - 140430Z

   The severe weather threat for Severe Thunderstorm Watch 214
   continues.

   SUMMARY...A large hail and damaging wind threat continues into the
   overnight hours.

   DISCUSSION...Several storms developed in southern Kansas with the
   only remaining storms being a left mover moving toward central
   Kansas and a right mover across northern Oklahoma. Despite
   relatively low reflectivity, both of these storms have had reports
   of severe hail indicating more of a LP storm mode. It is unclear how
   much longer these storms may persist. The 01Z HRRR insists storms
   should have already dissipated, but recent radar trends show
   additional cells developing across Barber county, KS, northwest
   Alfalfa county, OK, and Major county, OK. This uptick in activity
   could be associated with a southeastward moving mid-level shortwave
   as indicated by water vapor imagery and the veering mid-upper level
   flow from KVNX. If this additional convection develops, this could
   increase the potential for upscale growth and a greater wind threat
   into the overnight hours. However, inhibition is increasing and
   forcing is not that strong which leads to considerable uncertainty
   in the evolution of this convection. If more upscale growth appears
   likely, watch 214 may need to be expanded south to cover the threat.
