   ...THERE IS A MARGINAL RISK OF SEVERE THUNDERSTORMS FOR NORTHEASTERN
   NORTH CAROLINA AND FAR SOUTHEAST VIRGINIA...

   ...SUMMARY...
   Isolated severe thunderstorms are possible during the morning over
   northeastern North Carolina and far southeast Virginia.

   ...NC/VA...
   The mid-level low initially over the TN Valley will slowly migrate
   eastward into southwest VA during the period.  A front will extend
   from a low over the central Appalachians to eastern NC and southward
   to the FL Straits at the start of the period.  A moist/destabilizing
   warm sector will likely exist early Friday morning over parts of
   eastern NC and into far southeast VA.  Model guidance shows a broken
   band of convection near the front during the morning moving
   east-northeast and offshore into the coastal waters by late morning.
   Forecast soundings indicate that before the convection clears the
   coast, a risk for a supercell or two and linear segments may lend a
   narrow window of opportunity for isolated damaging gusts and/or a
   tornado.  

   Elsewhere, quiescent conditions will prevail across much of the
   remainder of the Lower 48 states.
