    Areas affected...eastern North Carolina and southeast Virginia

    Concerning...Tornado Watch 28...

    Valid 051923Z - 052100Z

    The severe weather threat for Tornado Watch 28 continues.

    SUMMARY...A damaging wind and tornado threat will persist through
    the afternoon across eastern North Carolina and southeast Virginia.

    DISCUSSION...Low 60s dewpoints have now advected northward ahead of
    the line across eastern North Carolina to near the Virginia border.
    This has resulted in weak surface based instability ahead of the
    squall line. As a result, convection has intensified (evidenced by
    increasing lightning activity) along the line early this afternoon.
    Expect additional strengthening of this line as the downstream
    environment continues to destabilize. Expect widespread damaging
    wind gusts and perhaps a few embedded tornadoes through the
    afternoon and into the early evening. Some discrete convection tried
    to form across eastern South Carolina and southeast North Carolina
    where mid 60s dewpoints are present. However, in the uncapped
    environment, cell interactions quickly resulted in a messy mode
    which has now congealed into part of the greater squall line. Given
    this trend over the past hour, do not anticipate any pre-squall line supercells. However, given the strength of the shear, a few embedded
    supercells could be possible through the afternoon and evening,
    particularly across southern North Carolina where greater
    instability is present.
