   Mesoscale Discussion 0743
   NWS Storm Prediction Center Norman OK
   0934 PM CDT Wed May 22 2019

   Areas affected...Parts of northeast Oklahoma through southwestern

   Concerning...Tornado Watch 212...

   Valid 230234Z - 230330Z

   The severe weather threat for Tornado Watch 212 continues.

   SUMMARY...Risk for tornadoes may continue another hour or two, risk
   for severe wind and hail continues into the overnight hours.

   DISCUSSION...Discrete supercell development persists within a narrow
   pre-frontal   corridor near Interstate-44, across northeastern
   Oklahoma into southern portions of the Missouri Ozarks.  This is
   where low-level shear and boundary layer CAPE (supported by surface
   dew points near 70f) remain maximized, and additional tornado
   development may not be out of the question into the 03-04Z time

   In general though, boundary-layer based storm development appears to
   be gradually waning, but convection rooted above the boundary layer
   is expected to persist, near/above the southeastward advancing
   front, but along a 30-40 kt southwesterly 850 mb jet axis.  This may
   continue to be accompanied by a risk for severe hail and perhaps
   some increase in potential for damaging wind gusts.
