   Areas affected...central and southern Arkansas

   Concerning...Severe potential...Watch unlikely 

   Valid 231304Z - 231500Z

   Probability of Watch Issuance...20 percent

   SUMMARY...A strong gust or two -- or marginal hailstone -- will
   remain possible across central/southern Arkansas over the next
   couple of hours.  Marginal/isolated nature of the risk should
   preclude WW issuance.

   DISCUSSION...Latest radar loop shows storms over southwestern
   Arkansas evolving a bit upscale linearly, with some bowing evident
   -- suggesting an at least somewhat-organized cold pool.  Flow
   through the lower troposphere remains moderate/southwesterly, and
   thus not overly supporting well-organized storms.  Additionally the
   morning LZK RAOB reveals an anticipated/nocturnally induced weakly
   stable surface-based layer.  These factors should act to limit
   overall wind risk, but with a stronger gust or two possible. 
   Marginal hail near severe levels may occur with a stronger updraft
   or two.  Overall however, given limited local risk apparent at this
   time, WW issuance is not expected at this time.
