    Areas affected...central/eastern NC and southern VA

    Concerning...Severe potential...Watch possible=20

    Valid 051605Z - 051800Z

    Probability of Watch Issuance...60 percent

    SUMMARY...At least isolated severe hail and damaging winds will be
    possible this afternoon along/ahead of a weak front from
    central/eastern North Carolina into southern Virginia. Monitoring
    for a potential severe thunderstorm watch.

    DISCUSSION...A compact mid-level jetlet, curling around the
    southeast quadrant of the broader OH Valley low and attendant
    trough, will support potential for occasional mid-level updraft
    rotation along a weak north/south-oriented baroclinic zone across
    central NC into south-central VA. Initial storm development is
    underway along this boundary, with more isolated activity expected
    near the southern NC coast. With eastern extent, hodograph structure
    will be less favorable as it progressively becomes more of a J to
    reverse-L shape. But this weakness in the hodograph may be
    compensated by greater boundary-layer heating and MLCAPE with
    eastern extent. Overall setup is expected to support
    north-northeastward moving storms with a mixed severe hail/damaging
    wind threat.
