    Areas affected...far eastern North Carolina

    Concerning...Severe potential...Watch unlikely=20

    Valid 211648Z - 211915Z

    Probability of Watch Issuance...20 percent

    SUMMARY...Isolated strong storms may develop this afternoon over far
    eastern North Carolina. Localized hail or wind may occur.

    DISCUSSION...Surface analysis shows a low over northeast
    NC/southeast VA, with a cold front extending westward across
    northern NC. South of this front, westerly winds and strong heating
    are steepening boundary layer lapse rates, and removing convective
    inhibition. Meanwhile, a narrow zone of mid 70s F dewpoints remains
    in place over far eastern NC. Continued heating will yield over 2000
    J/kg MLCAPE, beneath moderate westerlies aloft with around 50 kt
    deep layer shear.

    Although the westerly flow regime will eventually result in a drying
    air mass, a window may exist in the near term for a few strong to
    severe storms. Isolated marginal hail or a strong downburst cannot
    be ruled out.
