   Areas affected...Central North Carolina and eastern South Carolina.

   Concerning...Tornado Watch 26...

   Valid 051535Z - 051700Z

   The severe weather threat for Tornado Watch 26 continues.

   SUMMARY...Wind damage/tornado threat to increase by mid-day.

   DISCUSSION...A convective line has produced consistent wind damage
   this morning with a 52 knot gust at 1512Z at KBUY. This wind threat
   will continue and likely increase as the environment downstream
   destabilizes. In addition, low-level moisture advection and some
   heating through broken cloud cover should lead to 500 to 1000 J/kg
   MLCAPE by early afternoon across parts of eastern South Carolina and
   eastern North Carolina. Given 450+ m2/s2 0-1km SRH and 75 knots at
   1.5 km from the KRAX VWP, the embedded QLCS tornado threat and
   severe wind threat will likely increase as the line interacts with
   greater instability. In addition, a few embedded supercells may be
   possible where instability is greatest which could lead to regions
   of locally higher threat within the line. 

   Expect an increase in organization and intensity of the squall line
   (first indicated by the presence of lightning) within the next 1 to
   2 hours with the threat persisting through the afternoon/evening. An
   additional tornado watch will eventually be needed downstream of
   watch 26 across parts of eastern North Carolina and southeast
   Virginia.
