Mesoscale Discussion 0435
   NWS Storm Prediction Center Norman OK
   0836 AM CDT Wed Apr 22 2020

   Areas affected...central through eastern Oklahoma

   Concerning...Severe potential...Watch possible 

   Valid 221336Z - 221500Z

   Probability of Watch Issuance...60 percent

   SUMMARY...Storms including a few supercells developing through the
   morning will remain capable of producing large hail. Trends are
   being monitored for a severe thunderstorm watch.

   DISCUSSION...Early this morning storms continue developing across OK
   within a broad zone of warm advection and isentropic ascent north of
   a warm front and association with a 50 kt low-level jet. The
   atmosphere is moderately unstable with steep (8C/km) 700-500 mb
   lapse rates, along with effective bulk shear of 60+ kt. This
   environment is favorable for large hail, especially with any
   discrete supercell structures. Storms are expected to remain
   elevated through the morning limiting the primary threat to large
   hail, but isolated damaging wind gusts may increase with time.
