    Areas affected...Far southeast Virginia and eastern North Carolina

    Concerning...Severe Thunderstorm Watch 223...

    Valid 052207Z - 060000Z

    The severe weather threat for Severe Thunderstorm Watch 223
    continues.

    SUMMARY...Thunderstorms developing along and ahead of a cold
    front/outflow boundary will continue to see periods of
    intensification to severe limits through early evening across
    eastern North Carolina and into far southeast Virginia.

    DISCUSSION...Over the past hour, discrete/semi-discrete cells across
    eastern NC and southeast VA have shown a slight downturn in overall
    intensity and organization based on reflectivity
    structure/intensity, MRMS echo top/vertical ice metrics, and
    cloud-top temperatures. For cells developing along an eastward
    propagating, storm motions along/slightly behind the boundary are
    likely responsible for this trend. Regardless, the overall
    convective environment across NC and southeast VA remains favorable
    for organized convection. Latest RAP mesoanalysis estimates continue
    to show MLCAPE values upwards of 1500 J/kg and surface-based lifted
    indices between -6 to -8 C across parts of eastern NC ahead of the
    boundary. Additionally, the MHX VWP continues to sample deep-layer
    shear on the order of 40 knots. GOES visible imagery shows agitated
    cumulus along and ahead of the boundary, suggesting that new cell
    development remains possible. The expectation for the next couple of
    hours is that ongoing convection may see an uptick in intensity as
    it pushes east/northeast further into the buoyant air mass, and new
    convection may develop along/ahead of the boundary across eastern NC
    with an attendant hail/wind risk.
