   Mesoscale Discussion 1401
   NWS Storm Prediction Center Norman OK
   0605 PM CDT Tue Aug 04 2020

   Areas affected...Portions of central and western Nebraska

   Concerning...Severe potential...Watch unlikely 

   Valid 042305Z - 050100Z

   Probability of Watch Issuance...20 percent

   SUMMARY...Isolated large hail and locally damaging wind gusts
   possible late this afternoon and early evening. Activity should
   weaken and dissipate after sunset. No WW is expected.

   DISCUSSION...Scattered storms have developed along a surface
   boundary likely with some influence of an MCV in central South
   Dakota. Deep-layer shear is roughly perpendicular to the boundary
   and around 40 kts. Despite modest MLCAPE near 1000-1500 J/kg, a few
   storms may intensify and produce large hail and locally damaging
   wind gusts. With capping to the south, it is uncertain how far these
   storms will progress. If storms can cluster and grow upscale, a
   marginally greater wind threat would develop. Again, any cluster
   would likely propagate along the boundary where MLCIN would be
   minimized. With limited upper-level support, this activity will
   likely diminish after sunset. No WW is expected.
