   Day 2 Convective Outlook

   1241 AM CDT Sun Apr 23 2017

   Valid 241200Z - 251200Z

   ...THERE IS A MARGINAL RISK OF SEVERE THUNDERSTORMS ACROSS PARTS OF
   EASTERN SOUTH CAROLINA INTO SOUTHERN NORTH CAROLINA...

   ...SUMMARY...
   Thunderstorms associated with a marginal wind-damage threat will be
   possible on Monday across parts of eastern South Carolina and
   southern North Carolina.

   ...Eastern South Carolina/Southern North Carolina...
   An upper-level low is forecast to move eastward across central
   Georgia to the Atlantic coast on Monday. At the surface, a low is
   forecast to deepen and move off the coast from South Carolina. A
   cold front trailing the surface low, is forecast to move into the
   coastal sections of South Carolina by Monday afternoon. Thunderstorm
   development appears likely to take place along the front in eastern
   South Carolina with convection expanding northeastward with time
   during the afternoon as the surface low remains offshore but moves
   toward the coast of North Carolina. NAM forecast soundings from
   Charleston, South Carolina to Wilmington, North Carolina for Monday
   afternoon show weak instability (MLCAPE of 400 to 600 J/kg) with 0-6
   km shear of 25 to 35 kt. This combined with surface dewpoints in the
   mid 60s F may be enough for marginally severe wet downbursts with
   the stronger multicells.
