Areas affected...eastern/southern NC to the SC Midlands

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.
