    Concerning...Tornado Watch 32...

    Valid 082142Z - 082315Z

    The severe weather threat for Tornado Watch 32 continues.

    SUMMARY...The environment remains broadly favorable for damaging
    gusts and a tornado or two this afternoon across WW032.

    DISCUSSION...Across Tornado Watch 32, widespread convection is
    ongoing along a southward surging outflow across parts of southern
    MS and eastern LA. Transient supercell structures and bowing
    segments have been noted with this activity over the past several
    hours. The environment remains broadly favorable for damaging gusts
    of 50-60 mph and/or a brief tornado, given ~1000 J/kg of MLCAPE and
    50-60+ kt of effective shear. However, the surging nature of outflow
    and numerous storm interactions may continue to limit greater severe
    potential within this broader cluster.

    Farther south, more discrete convection is ongoing across
    southeastern LA and far southern MS. An impressive kinematic
    parameter space with strong low-level shear (0-1 km SRH of 300-400
    m2/s2) remains in place along with minimal inhibition. WOFS and
    other hi-res guidance continue to suggest a favorable environment
    for damaging gusts of 55-65 mph and a tornado, should better
    organized supercells emerge. With this in mind, the severe risk will
    likely continue as storms track east/northeastward the warm front
    over parts of southern AL.
