    Areas affected...central into northern MS...far southeast AR...far
    northeast LA

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

    Valid 091706Z - 091930Z

    Probability of Watch Issuance...20 percent

    SUMMARY...Isolated wet microbursts will probably result in localized
    gusts 45-60 mph and pockets of wind damage this afternoon. The
    disorganized character of the thunderstorm threat will likely
    preclude a severe thunderstorm watch from being issued.

    DISCUSSION...Visible satellite/radar mosaic shows developing
    thunderstorms over north-central MS and a separate thunderstorm
    cluster intersecting trailing outflow over northwest MS. Cloud
    breaks over north-central MS and mostly clear skies over central MS
    will favor strong heating for the next few hours as temperatures
    warm into the mid-upper 80s deg F. A very moist airmass,
    characterized by low-mid 70s dewpoints and PW around 2 inches, will
    further destabilize and yield around 2500-3000 J/kg MLCAPE by early
    afternoon. Weak flow through the troposphere will result in
    slow-moving cells and clusters. The main threat with the stronger
    water-loaded cores (higher echo tops and marginally severe MESH
    cores) will be localized gusts in the 45-60 mph range. Pockets of
    tree damage are anticipated to be the primary end-result with the
    most intense storms.
