   Areas affected...northwestern South Carolina into south-central
   North Carolina

   Concerning...Tornado Watch 148...

   Valid 260058Z - 260230Z

   The severe weather threat for Tornado Watch 148 continues.

   SUMMARY...Local/brief tornado risk may spread out of WW 148 into
   south-central North Carolina.

   DISCUSSION...While severe risk has diminished across most of Tornado
   Watch 148, a small corridor exists over northwestern South Carolina
   near/to the cool side of the wedge front where a few supercell
   storms are ongoing.  While likely to be slightly elevated just to
   the cool side of the front, the storms continue to exhibit weak
   low-level rotation.  Given the presence of the low-level boundary
   lying west-to-east across this area, a brief tornado spin-up remains
   a possibility over the next hour or so.

   While this slightly-more-favorable zone of minimal CAPE but ample
   shear extends east of the watch into south-central North Carolina, a
   new Tornado Watch is not expected, as the already marginal
   thermodynamic environment diurnally worsens.
