    Mesoscale Discussion 2325
    NWS Storm Prediction Center Norman OK
    1136 AM CST Sun Dec 10 2023

    Areas affected...Portions of central North Carolina into far
    south-central Virginia

    Concerning...Severe potential...Watch possible=20

    Valid 101736Z - 101930Z

    Probability of Watch Issuance...40 percent

    SUMMARY...Severe risk is evolving over portions of central North
    Carolina into far south-central Virginia this afternoon. Brief
    tornadoes and/or damaging gusts are the main concern.

    DISCUSSION...A loosely organized cluster of storms has been evolving
    northward along a weak north/south-oriented baroclinic zone draped
    across parts of central NC during the last couple hours. This storm
    cluster has shown signs of transient midlevel updraft
    rotation/supercell characteristics, and recent low-level updraft intensification. While instability is fairly limited, continued warming/moistening of the inflow for this activity is expected
    during the next few hours. Additionally, the RAX VWP depicts strong
    low-level shear, characterized by 30 kt of 0-1 km bulk shear and
    ample streamwise vorticity for an east-northeastward-moving storm.
    Low-level shear will also continue strengthening amid a
    strengthening low-level jet. While the tornado risk may remain
    localized (especially near the baroclinic zone) in the short-term,
    the tornado/damaging wind risk should increase across the area with
    time.=20

    Farther east toward the coast, the severe risk should also gradually
    increase with time this afternoon, and this area is being monitored
    as well.
