   Areas affected...Northeast Arkansas into parts of Tennessee and
   Kentucky

   Concerning...Severe potential...Watch unlikely 

   Valid 101915Z - 102115Z

   Probability of Watch Issuance...20 percent

   SUMMARY...Widely scattered thunderstorms will affect areas from
   northeast AR into portions of KY/TN through the afternoon.  Locally
   damaging winds are possible. A watch is unlikely.

   DISCUSSION...Thunderstorms have begun to develop along an axis from
   northern AR into parts of KY/TN.  This is along and south of a
   surface boundary, where temperatures have warmed into the upper
   80-mid 90s.  High PWAT values around 2 inches, MLCAPE over 1500
   J/kg, and strong daytime heating suggest a few storms may
   occasionally produce gusty/damaging winds.  Mid-level westerly flow
   of 25-30 knots may also encourage a few organized multicell
   clusters.  Present indications are that the coverage of severe will
   be limited.
