    Areas affected...portions of eastern North Carolina

    Concerning...Severe Thunderstorm Watch 404...

    Valid 272159Z - 272300Z

    The severe weather threat for Severe Thunderstorm Watch 404
    continues.

    SUMMARY...The potential for occasionally damaging wind gusts
    continues across portions of Severe Thunderstorm Watch 404,
    including eastern North Carolina.

    DISCUSSION...Ongoing thunderstorm activity has congealed into a
    convective cluster extending from near New Bern, NC, into the
    northern Outer Banks, with a couple of wind gusts measured in the
    40-45 mph range over the past 1-2 hours. While weak effective shear
    (generally 25 kts or less) will continue to limit storm
    organization, around 1500-2000 J/kg MLCAPE and a very moist air mass
    (PWAT values of 2+ inches) will continue to promote water-loaded
    downdrafts capable of strong to occasionally damaging wind gusts as
    this cluster progresses eastward before eventually moving offshore.
    Locally greater potential may exist along the northern portions of
    the cluster where the latest objective analysis suggests that
    mid-level flow and effective shear are marginally greater.
