    Mesoscale Discussion 0682

    Areas affected...portions of eastern North Carolina

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

    Valid 041816Z - 042045Z

    Probability of Watch Issuance...5 percent

    SUMMARY...An isolated damaging gust threat may accompany the
    stronger storms today, and an instance or two of hail cannot be
    ruled out. A WW issuance is not expected.

    DISCUSSION...Thunderstorms are increasing in coverage and intensity
    along a confluence zone in southern NC per latest MRMS mosaic radar
    imagery and visible satellite. Surface temperatures remain
    relatively cool given considerable cloud cover. However, surface
    dewpoints are in the upper 60s to 70 F, which is supporting marginal
    buoyancy in spots (i.e. 500+ J/kg MLCAPE). A southwesterly 500 mb
    jet max is glancing by the Carolina Piedmont to the west,
    contributing to 35 kts of effective bulk shear ahead of the
    developing/ongoing storms. As such, any storms that can take
    advantage of locally higher pockets of buoyancy may intensify enough
    to produce a few damaging wind gusts and perhaps a couple instances
    of marginally severe hail. Nonetheless, the overall sparse nature of
    the severe threat precludes a WW issuance.
