   Mesoscale Discussion 0276
   NWS Storm Prediction Center Norman OK
   1019 PM CDT Sun Apr 15 2018

   Areas affected...Central/Southeast VA...Eastern NC

   Concerning...Tornado Watch 54...55...

   Valid 160319Z - 160445Z

   The severe weather threat for Tornado Watch 54, 55 continues.

   SUMMARY...The tornado threat continues across Tornado Watches 54 and
   55.

   DISCUSSION...Long-lived convective line continues to progress
   eastward/northeastward across central VA and eastern NC. Damaging
   wind gusts have been reported as this line moves across central NC.
   Several supercells also developed ahead of this line across central
   VA. Strong wind fields (i.e. 60 kt near 1 km) have been sampled by
   the MHX and AKQ VADs, contributing to strong low-level helicity and
   shear. Additionally, the airmass remains unstable enough for
   continue storm development. As such, the potential for damaging wind
   gusts and tornadoes continues along and ahead of the line. Any cells
   that develop ahead of the line are particularly favored for updraft
   rotation capable of producing a tornado (evidenced by the supercells
   across central VA).
