    Areas affected...Parts of NC and southern VA

    Concerning...Severe Thunderstorm Watch 498...

    Valid 192248Z - 200015Z

    The severe weather threat for Severe Thunderstorm Watch 498
    continues.

    SUMMARY...Locally damaging wind remains possible through early
    evening.

    DISCUSSION...Widely scattered storms are ongoing across parts of NC
    into far southern VA. With MLCAPE of 2000-3000 J/kg and large PW in
    place, occasionally vigorous updrafts and subsequent downdrafts will
    remain possible through early evening. However, the widely scattered
    storm coverage and lack of sustained storm clustering has limited
    coverage of the damaging-wind threat thus far.

    The most favorable effective shear (25-35 kt) resides across
    southern VA into northeast NC, though storms have remained isolated
    across these areas. While coverage may remain rather sparse in this
    area, any new or ongoing cells may be able to persist through the
    early evening with a threat of localized damaging wind. Farther
    south, the weaker shear will continue to result in more of a pulse
    character to storm development/evolution, though the large PW will
    support potential for wet microbursts.

    A gradual decrease in the severe wind threat is expected with time
    through the evening. However, nocturnal cooling/stabilization will
    be slow within the very moist environment, and a localized
    wind-damage threat may persist beyond the 00 UTC expiration time of
    WW 498.
