    Areas affected...Parts of central Mississippi

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

    Valid 221006Z - 221200Z

    Probability of Watch Issuance...20 percent

    SUMMARY...A brief tornado and locally damaging gusts remain
    possible.

    DISCUSSION...Preceding a midlevel wave approaching the lower MS
    Valley, convection is evolving within low-level confluence bands in
    central MS -- where a moist air mass (lower 70s dewpoints) is in
    place. The JAN VWP is sampling a gradually strengthening low-level
    jet (around 40 kt at 1 km AGL) and an associated clockwise-curved
    low-level hodograph (around 200 m2/s2 0-1 km SRH). Despite weak
    buoyancy, the rich boundary-layer moisture and enhanced streamwise
    vorticity are contributing to a locally favorable environment for
    transient, low-topped supercell structures. A brief tornado was
    reported at 938 UTC southwest of Jackson, MS, and an additional
    brief tornado and locally damaging gusts will remain possible
    beneath the core of the 30-40-kt LLJ as it translates northward
    across central MS.
