   Areas affected...eastern Oklahoma through western Arkansas

   Concerning...Severe Thunderstorm Watch 201...

   Valid 221415Z - 221545Z

   The severe weather threat for Severe Thunderstorm Watch 201
   continues.

   SUMMARY...Storms are approaching the eastern bound of WW 201. Some
   threat for isolated strong wind gusts may persist through the
   remainder of eastern OK into western AR, but threat is expected to
   remain too marginal for another WW.

   DISCUSSION...Line of storms from southwest MO through eastern OK is
   moving east at around 30 kt. Overall trend has been for storms to
   decrease in intensity and remain below severe limits. Surface
   temperatures are only in upper 60s F downstream from the line with
   an inversion also present in the surface to 850 mb layer. Widespread
   clouds should slow destabilization of the boundary layer which along
   with weak vertical shear should limit organization and intensity
   next few hours. Nevertheless, there appears to be enough lift along
   the outflow boundary to maintain the storms into western AR where a
   couple of strong wind gusts cannot be ruled out.
