   Concerning...Tornado Watch 414...

   Valid 040407Z - 040600Z

   CORRECTED FOR HURRICANE SYMBOL

   The severe weather threat for Tornado Watch 414 continues.

   SUMMARY...The tornado threat will likely continue across much of
   eastern North Carolina over the next few hours. The tornado threat
   is expected to increase across southeast Virginia where a new
   tornado watch will likely be needed.

   DISCUSSION...The center of Hurricane Isaias is about 20 statute
   miles southwest of Wilmington, North Carolina. Two bands of heavy
   rainfall are present around the center. The first and southern
   most-band is located in southern North Carolina near Wilmington. The
   second and northern-most band is located in eastern North Carolina
   near Morehead City, extending northwestward to about 75 miles
   inland. The Morehead City WSR-88D VWP shows very strong low-level
   shear with 0-1 km storm relative helicity near 600 m2/s2. This will
   be favorable to continue a tornado threat with the more discrete
   cells across eastern North Carolina late this evening into the early
   overnight period. 

   The tornado threat should spread into southeast Virginia as
   low-level shear and theta-e increases. A new tornado watch will be
   necessary across parts of southeast Virginia over the next few
   hours.
