   Mesoscale Discussion 0968
   NWS Storm Prediction Center Norman OK
   0338 PM CDT Thu Jun 08 2017

   Areas affected...Southwest Kansas into the Oklahoma and Texas

   Concerning...Severe potential...Watch possible 

   Valid 082038Z - 082245Z

   Probability of Watch Issuance...60 percent

   SUMMARY...Isolated severe thunderstorms capable of mainly large hail
   are expected to form between 22-23Z.

   DISCUSSION...Visible imagery shows outflow boundaries from southwest
   KS into the eastern OK panhandle, and across the eastern TX
   panhandle. South and west of these boundaries, the air mass
   continues to heat with temperatures in to the mid 80s and with
   dewpoints ranging from the 50s to the lower 60s. These aggregate
   outflows are also reflected in the surface pressure fields with a
   meso high over south central KS and north west OK. This in turn will
   likely maintain southeasterly surface winds through evening, aiding
   in overall shear profiles.

   One or more storms are expected to form across southwest KS into the
   OK panhandle prior to 00Z, with other sporadic activity possibly
   developing out of the TX panhandle CU field as well west through
   southeast of Amarillo. Modest northwesterly flow aloft atop the
   low-level southeasterlies may support southward-moving cells,
   perhaps supercellular at times, with large hail of 1.50-2.00" the
   primary threat. 

   With time, activity may merge with a possible outflow or MCS
   developing southeastward out of NM.
