Areas affected...Portions of southeastern NC and northeastern SC

Concerning...Severe Thunderstorm Watch 131...

Valid 202300Z - 210030Z

The severe weather threat for Severe Thunderstorm Watch 131
continues.

SUMMARY...The severe risk will continue across Severe Thunderstorm
Watch 131 for the next few hours. Primary concerns are isolated
large hail and locally damaging gusts.

DISCUSSION...Two main corridors of severe storms persist across
portions of southeastern NC and northeastern SC this evening. Closer
to the southeastern NC coast, recent storm mergers have yielded a
consolidated supercell which is generally anchored to an
outflow-modified sea breeze boundary. This storm will likely
continue drifting slowly south-southeastward to the coast, with a
risk of locally damaging gusts (50-65 mph) and isolated large hail
(up to 1.5 inches in diameter). Slightly farther northwest (over the
northeastern SC/southeastern NC border), splitting storms with
occasional supercell structure are ongoing amid a long/straight
hodograph environment and moderate surface-based instability. These
storms will continue to pose a risk of isolated large hail as well,
in addition to severe gusts given a steep low-level lapse rate plume
extending toward the inflow of this activity. The severe threat will
generally persist until storms move off the coast in the next 3-4
hours.
