   Mesoscale Discussion 0770
   NWS Storm Prediction Center Norman OK
   0322 PM CDT Mon May 13 2024

   Areas affected...southern Texas into far eastern Lousiana

   Concerning...Severe Thunderstorm Watch 235...237...

   Valid 132022Z - 132215Z

   The severe weather threat for Severe Thunderstorm Watch 235, 237
   continues.

   SUMMARY...Severe threat continues for WW235 and WW237.

   DISCUSSION...Storm mode across southern Texas has gradually
   transitioned to become linear over the last hour, with two broken
   line segments moving eastward. The more western line of convection
   has had recent reports of gusts up to 52 mph and golf ball size
   hail. The main threat with this more linear convection will remain
   damaging wind and large hail, with potential for a tornado or two
   through the evening. 

   More discrete supercells have developed across the south Texas Brush
   Country. This is moving eastward into an unstable airmass where
   MLCAPE around 3000-4000 J/kg overlaps deep layer shear around 50
   kts. This more discrete supercell activity will have the potential
   to produce very large hail up to 1-3.5 inches.
