   The severe weather threat for Severe Thunderstorm Watch 200
   continues.

   SUMMARY...Isolated severe gusts will remain possible with the
   southeastward-moving squall line over the next few hours.

   DISCUSSION...Radar mosaic shows a mature squall line extending from
   the northeast TX Panhandle eastward into north-central OK and arcing
   northeast to the Wichita vicinity.  Surface observations via the OK
   Mesonet have recorded strong gusts primarily in the 40-50 mph range
   with a recently measured 73 mph gust at Lahoma, OK at 330am CDT. 
   Additionally, surface observations indicate a meso-high is located
   over southwestern KS.  

   KVNX VAD is now sampling a stout rear inflow jet with 50-55 kt flow
   around 0.5-1 km ARL.  The well-organized character of the
   front-to-rear convective system will likely continue southeast
   across the I-35 and I-44 corridors in central OK during the next few
   hours.  Given the observational trends in peak gusts, current
   thinking is an additional watch is not needed given the isolated
   coverage of severe gusts and gradual weakening trend of the squall
   line.
