   Mesoscale Discussion 0390
   NWS Storm Prediction Center Norman OK
   1059 PM CDT Mon Apr 08 2024

   Areas affected...TX Permian Basin vicinity

   Concerning...Severe potential...Watch possible 

   Valid 090359Z - 090630Z

   Probability of Watch Issuance...60 percent

   SUMMARY...Severe thunderstorm development will be possible
   overnight, with a threat of large hail.

   DISCUSSION...Low-level moisture continues to stream northwestward
   late this evening into portions of the TX Permian Basin region.
   Meanwhile, WV and IR imagery suggests that ascent related to the
   deep upper-level trough over the Southwest is beginning to
   overspread the region. While timing remains uncertain, storm
   development will become increasingly likely overnight, especially
   near/north of a southward-moving cold front. Steep midlevel lapse
   rates, MUCAPE increasing into the 1000-2000 J/kg range, and
   effective shear of 40+ kts will support elevated supercell
   potential, with an attendant threat of large hail in the 1.5 - 2
   inch diameter range. 

   Severe-storm coverage remains somewhat uncertain overnight and could
   remain rather isolated, but eventual watch issuance is possible
   given the potential for elevated supercells.
