   Mesoscale Discussion 0884
   NWS Storm Prediction Center Norman OK
   0907 PM CDT Sat May 27 2017

   Areas affected...northeastern TX Panhandle...northwest and far
   western OK

   Concerning...Severe potential...Severe Thunderstorm Watch likely 

   Valid 280207Z - 280300Z

   Probability of Watch Issuance...80 percent

   SUMMARY...A severe hail and severe gust risk will likely continue
   southeastward into parts of northwest and far western Oklahoma.

   DISCUSSION...Radar imagery (9-km CAPPI, MRMS MESH) shows intense
   discrete storms over the OK and TX Panhandles moving southeast. 
   These storms will exit the southeastern portion of severe
   thunderstorm watch #281 during the next 1-2 hours.  Water-vapor
   imagery shows a potent shortwave trough moving southeast across the
   Sangre de Cristos and into the south-central High Plains.  The
   appreciable mid- to upper-level forcing for ascent will likely aid
   in the storms longevity given favorable shear/buoyancy in place to
   the north of a surface front.  A measured 68 mph gust was recorded
   at the Hooker, OK mesonet at 0150Z.  Severe hail and severe gusts
   will likely accompany these storms for the next couple of hours and
   a new severe thunderstorm watch will probably be considered for
   portions of far western and northwestern OK in an hour or so.
