    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.
