    Areas affected...portions of central and eastern North Carolina into
    coastal South Carolina

    Concerning...Severe potential...Tornado Watch likely=20

    Valid 161515Z - 161645Z

    Probability of Watch Issuance...80 percent

    SUMMARY...South of a lifting warm front, a destabilizing air mass
    will likely support several rounds of strong to severe
    thunderstorms. Very strong kinematic fields will favor damaging
    winds and the potential for tornadoes (some strong). A new Tornado
    Watch will likely be needed by midday, though the exact timing
    remains unclear.

    DISCUSSION...Morning surface and satellite and surface obs show
    diurnal warming and subsequent destabilization is occurring south of
    a warm front lifting across parts of eastern NC, far southern VA and
    across coastal SC. South of the front, temperatures warming into the
    upper 60s and low 70s F with dewpoints in the 60s F will support
    weak but sufficient buoyancy for numerous strong to severe storms
    (500-1000 J/kg MLCAPE most likely). Very strong kinematic fields
    will support a mixed convective mode, with multiple clusters, line
    segments and possibly semi-discrete supercells.

    Despite some uncertainty on the magnitude of the destabilization,
    very strong kinematic fields are already present and likely to
    intensify as a 120+ kt mid-level jet approaches this afternoon. ESRH
    of 200-300 m2/s2 will support updraft rotation, and the potential
    for tornadoes, especially with any semi-discrete supercells that can
    be maintained. Some of the tornadoes could be strong and/or
    long-tracked given storm motions exceeding 50 kts. While the exact
    details and storm mode remain unclear due to multiple rounds and
    numerous storm interactions, the severe risk is likely to increase
    morning, signaling the need for a new Tornado Watch by midday.
