    Areas affected...Parts of the Lower Mississippi Valley

    Concerning...Severe potential...Watch unlikely

    Valid 032240Z - 040115Z

    Probability of Watch Issuance...20 percent

    SUMMARY...The potential for a brief/weak tornado or two and locally
    damaging wind gusts will continue spreading eastward over the next
    few hours. The overall severe threat is expected to remain fairly
    marginal and localized.

    DISCUSSION...A NNE/SSW-oriented broken line of thunderstorms is
    tracking eastward across parts of LA into southern AR, with
    additional shallow cellular storms ahead of the line. This activity
    will continue tracking eastward across the Lower MS Valley over the
    next few hours -- in tandem with a robust midlevel trough and
    related cold front. The LCH 18Z sounding sampled a moist air mass
    ahead of these storms, with lower 70s dewpoints in LA, and
    middle/upper 60s dewpoints extending northward into the Mid-South.
    Despite poor lapse rates, the associated weak surface-based buoyancy
    and small clockwise-curved low-level hodographs (sampled by the POE
    VWP) will continue to support embedded rotating cells in the line,
    and shallow/transient rotating showers/storms immediately ahead of
    the line. A brief/weak tornado or two and locally damaging gusts
    will remain possible with this activity, however, with the core of
    the low-level jet shifting northward and aforementioned weak
    buoyancy, the overall severe threat is expected to remain fairly
    marginal and localized.
