   Areas affected...eastern North Carolina into far southeast Virginia

   Concerning...Tornado Watch 519...

   Valid 250346Z - 250645Z

   The severe weather threat for Tornado Watch 519 continues.

   SUMMARY...The threat for isolated damaging gusts or a brief tornado
   continues across eastern North Carolina, and far southeast Virginia.

   DISCUSSION...Surface analysis shows dewpoints have risen into the
   mid 60s F as far north as southeast VA, providing a few hundred J/kg
   of MLCAPE. While the greatest supercell potential still appears to
   be offshore and over the Outer Banks, a line of shallow convection
   continues to show better reflectively presentation along the cold
   front. Ahead of this line, pressure falls continue, and surface
   based parcels with mid 60s F dewpoints suggest strong gusts, or
   perhaps a QLCS tornado, remain possible until the front clears the
   coast. The AKQ VWP shows 0-1 SRH around 400 m2/s2, supporting
   low-level rotation.
