    Areas affected...Parts of northern/central MS and northern/central
    AL

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

    Valid 262323Z - 270130Z

    Probability of Watch Issuance...20 percent

    SUMMARY...Isolated strong to severe storms will remain possible for
    the next next few hours. The main concern will be severe hail and
    locally damaging gusts.

    DISCUSSION...The latest radar data depicts scattered thunderstorms
    evolving along a weak surface boundary and ahead of a subtle surface
    wave in northern/central MS into northern/central AL. A few of these
    storms have recently intensified and are capable of producing severe
    hail. Despite the loss of daytime heating, modest midlevel lapse
    rates atop lower 60s dewpoints are yielding around 1000 J/kg MUCAPE
    ahead of these storms. This buoyancy, coupled with a long/straight
    hodograph (50-60 kt of 0-6 km shear per GWX VWP) may continue to
    favor a couple organized cells, to include marginal/transient
    supercell structures. Given weak large-scale ascent, these storms
    may remain mostly discrete/semi-discrete and pose a risk of isolated
    severe hail for the next couple hours. However, storm mergers and
    localized upscale growth into clusters along the boundary could also
    support locally damaging gusts. Given the gradual onset of
    boundary-layer nocturnal cooling and limited forcing for ascent, the
    overall severe risk is expected to remain too localized/brief for a
    watch.
