   The severe weather threat for Severe Thunderstorm Watch 258
   continues.

   SUMMARY...Threat for damaging wind gusts and isolated hail continues
   across far east-central AR, western TN, and northern MS.

   DISCUSSION...Convective line continues to move southeastward through
   western TN and adjacent far east-central AR. Current estimates
   places the storm motion at 30-35 kt. At this speed, the line should
   reach the TN/MS border around 19Z. However, given the storms now
   developing ahead of the line, there is some potential for more
   discrete forward propagation, which would result in a faster storm
   motion. This downstream cellular development is occurring in a very
   unstable air mass (i.e. MLCAPE over 3000 J/kg per 18Z mesoanalysis),
   which will support robust updrafts. This more cellular development
   will promote an increased risk for isolated hail, both within the
   cells and as a result of mergers with the convective line. The
   threat for damaging wind gusts also continues across the region.
