   Mesoscale Discussion 0715
   NWS Storm Prediction Center Norman OK
   0658 PM CDT Sun May 24 2020

   Areas affected...West-central Texas

   Concerning...Severe potential...Watch possible 

   Valid 242358Z - 250200Z

   Probability of Watch Issuance...60 percent

   SUMMARY...A severe threat may develop across parts of west-central
   Texas over the next couple of hours. Wind damage and hail would be
   the primary threat. Weather watch issuance may be needed.

   DISCUSSION...Radar imagery shows a large cluster of strong to severe
   thunderstorms across west Texas. These storms are moving through a
   moderately unstable airmass where surface dewpoints are generally
   around 60 F. In spite of relatively weak deep-layer shear with the
   DYX WSR-88D VWP showing 20 kt of 0-6 km shear, low-level lapse rates
   have become steep. The RAP has a pocket of 0-3 km lapse rates near
   9.0 C/km to the north of San Angelo. This should be enough for an
   isolated wind damage threat as multicell convection moves
   northeastward across west-central Texas. Hail could also occur with
   the stronger updrafts. These storms will converge with an outflow
   boundary coming from the east which may result in increase in the
   severe threat later this evening.
