   Areas affected...far southeast KS...northeast into central OK

   Concerning...Tornado Watch 234...

   Valid 250056Z - 250200Z

   The severe weather threat for Tornado Watch 234 continues.

   SUMMARY...Severe gusts 60-70mph will likely focus where the squall
   line is oriented north-south and more favorably aligned with the
   mean flow.

   DISCUSSION...Radar mosaic shows a line echo wave pattern (lewp) to
   the west of the I-44 corridor in OK and extending northeastward
   through southeast KS.  The 00z Norman, OK raob showed a lowest 100mb
   mean mixing ratio around 15 g/kg with steep lapse rates (8 degrees
   C/km) located above a capping inversion (2100 J/kg MLCAPE).  The
   veering and strengthening wind profile with height sampled by the
   Norman, OK raob will support storm organization with the mean flow
   around 215 degrees/35kt.  Expecting the segments of the squall line
   more orthogonal with the mean wind to be the mesoscale areas where
   an enhanced risk for wind damage and 60-70mph gusts during the next
   1-2 hours.  The two separate areas include the greater OKC metro and
   portions of Osage County, OK into adjacent portions of southeast KS
   where the severe part of the LEWP structure is likely to move.
