   Concerning...Tornado Watch 200...

   Valid 080823Z - 081030Z

   The severe weather threat for Tornado Watch 200 continues.

   SUMMARY...A tornado and wind-damage threat may continue for a few
   more hours across WW 200. The threat may affect parts of far
   northwest Mississippi and far southwest Tennessee later this
   morning. A watch extension has been done to account for this
   possibility.

   DISCUSSION...The latest hi-resolution radar imagery from Little
   Rock, AR shows a cluster of strong thunderstorms located about 30
   statute miles to the east of Little Rock. A supercell is embedded
   toward the eastern edge of the cluster. The RAP is analyzing
   moderate instability across eastern Arkansas, with MLCAPE generally
   ranging from 2000 to 2500 J/kg. This will help to maintain
   convective development as the cluster moves eastward over the next
   few hours. In addition, the Little Rock WSR-88D VWP has 0-6 km shear
   near 45 knots, with 0-1 km storm-relative helicity just above 100
   m2/s2. This should continue to support an isolated tornado threat
   with supercells. A wind-damage threat may also accompany any cells
   that remain organized.
