   Areas affected...portions of central/southern Arkansas

   Concerning...Severe Thunderstorm Watch 477...

   Valid 311438Z - 311615Z

   The severe weather threat for Severe Thunderstorm Watch 477
   continues.

   SUMMARY...Convection continues to weaken across central Arkansas.

   DISCUSSION...A cluster of storms over central Arkansas will continue
   to percolate southeastward through the remainder of the morning
   hours. While the overall severe threat has diminished as convection
   has weakened, some sub-severe, but gusty winds could still accompany
   this activity. The downstream airmass will continue to destabilize
   with increasing daytime heating. However, convection will be on the
   southern fringe of stronger effective shear and encounter poor
   midlevel lapse rates. This should limit any re-intensification of
   convection through early afternoon. A downstream severe thunderstorm
   watch is not expected, and WW 477 is likely to be cancelled before
   the 19z expiration time.
