   Areas affected...Southern Appalachians

   Concerning...Severe Thunderstorm Watch 282...

   Valid 280246Z - 280415Z

   The severe weather threat for Severe Thunderstorm Watch 282

   SUMMARY...A line of thunderstorms, some severe, will continue to
   move slowly south and east into the overnight. Hail and strong/gusty
   winds will be possible with the strongest thunderstorms.

   DISCUSSION...A quasi-linear convective system has organized across
   portions of eastern Tennessee and northwestern North Carolina. Here,
   most unstable CAPE around 1000 J/kg and deep-layer shear around 50
   knots will continue to support organized thunderstorms. Hail and
   strong/gusty winds will be possible, especially with the strongest
   thunderstorm cores. One potential mitigating factor for a more
   widespread wind potential into the overnight will be the increasing
   surface inhibition and decreasing low-level lapse rates owing to the
   loss of daytime heating.
