    Mesoscale Discussion 0850

    Areas affected...South Carolina

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

    Valid 211656Z - 211900Z

    Probability of Watch Issuance...20 percent

    SUMMARY...Storms capable of isolated hail and damaging wind gusts
    will be possible this afternoon. WW issuance is unlikely.

    DISCUSSION...Thunderstorms have recently begun increasing in
    coverage and intensity across SC, in association with a weak
    midlevel trough noted on WV imagery. While deep-layer shear is
    rather weak across the region, relatively cool midlevel temperatures
    and MLCAPE in excess of 2000 J/kg will support a hail risk with
    stronger pulse storms and weak multicell clusters that may develop
    over time. In addition, relatively large PW values may support a
    threat of isolated wet microbursts. Due to the relatively
    disorganized nature of the threat, watch issuance is unlikely.
