    Areas affected...Far southeast Virginia into northeast North
    Carolina

    Concerning...Severe Thunderstorm Watch 444...

    Valid 200100Z - 200300Z

    The severe weather threat for Severe Thunderstorm Watch 444
    continues.

    SUMMARY...Some severe threat will persist across far southeast
    Virginia and into northeast North Carolina through 03 UTC as a line
    of storms continues to push east.

    DISCUSSION...A line of thunderstorms continues to push east along
    and just south of the VA/NC border. The northern segment of this
    line remains favorably oriented nearly orthogonal to low-level shear
    vectors per regional VWP observations and the recent 00 UTC MHX
    sounding, which will help maintain some degree of storm
    organization. The southward propagation of an outflow boundary out
    of southeast VA will likely shunt the focus for additional robust
    convective development within the line into far southeast
    VA/northeast NC through 03 UTC. Although velocity imagery from KAKQ
    has shown a weakening wind signal over the past half hour, GOES IR
    imagery continues to show deep/robust updraft development, and the
    rich low-level moisture in place should help modulate the influence
    of nocturnal cooling/stabilization to some degree. Consequently, an intensification of low-level winds, and perhaps some hail threat,
    may materialize downstream.

    Further southwest, the southern portion of the line has become
    outflow dominant with deep convection well displaced behind the
    outflow boundary. Despite this trend, the buoyant environment
    sampled by the MHX sounding may continue to support robust, though
    somewhat transient, updrafts with an attendant risk of sporadic hail
    and periodic strong/severe downbursts.
