   Areas affected...Parts of east-central Oklahoma into far
   west-central Arkansas

   Concerning...Tornado Watch 292...

   Valid 192330Z - 200100Z

   The severe weather threat for Tornado Watch 292 continues.

   SUMMARY...Favorable corridor for continuation of strong/intense
   tornadoes continues across east-central Oklahoma into west-central
   Arkansas.

   DISCUSSION...A couple intense supercell clusters are tracking
   east-northeastward across east-central Oklahoma -- one of which has
   a history of producing tornadoes (likely strong/intense). These
   storms are moving into the core of the low-level jet -- where the
   SRX VWP is sampling around 260 m2/s2 0-500m SRH. Given this very
   favorable streamwise vorticity, established supercell clusters, and
   strong surface-based instability, the risk of strong to intense
   tornadoes should continue for the next few hours.
