   Concerning...Severe Thunderstorm Watch 554...

   Valid 182132Z - 182300Z

   The severe weather threat for Severe Thunderstorm Watch 554
   continues.

   SUMMARY...Sporadic tree damage should persist through about dusk
   with strong gusts from 40-60 mph.

   DISCUSSION...An arcing broken convective band with loose multicell
   clustering is ongoing from northeast NC westward to central NC and
   then southwestward into upstate SC. Outflow attendant to the more
   westward portion of the band has pushed south of the stronger
   mid-level flow over southern VA per area VWPs. As such, overall
   organizational potential should remain weak, but might be slightly
   better across southern NC as convection upstate overspreads the
   southward-sinking outflow in the southern NC Piedmont. With a fairly
   uniform plume of moderate buoyancy characterized by MLCAPE of
   1500-2000 J/kg, sporadic strong gusts capable of tree damage will
   remain possible, before convection likely weakens after sunset.
