    Areas affected...much of Arkansas into southern Tennessee and
    northern Mississippi

    Concerning...Severe Thunderstorm Watch 322...

    Valid 252033Z - 252200Z

    The severe weather threat for Severe Thunderstorm Watch 322
    continues.

    SUMMARY...The severe risk continues across much of WW322. Damaging
    winds remain the primary threat though some hail with more scattered
    convection is also possible.

    DISCUSSION...As of 2030 UTC, regional radar imagery showed gradual intensification of the ongoing convective cluster across
    northwestern portions of WW322. Continued upscale growth of this
    cluster is likely this afternoon/evening as the expanding cold pool
    continues to interact with a broad warm and unstable air mass south
    of the East-West stationary front. The expectation continues to be
    for one or more bowing clusters to emerge from this convection, and
    spread eastward with a risk for damaging winds and perhaps an
    embedded tornado or two.

    Additional, more scattered, convection has also developed across
    much of the warm sector this afternoon. Given the robust buoyancy
    (3,000 J/kg of MLCAPE), some hail and occasional damaging winds are
    also possible with these storms. However, the main risk is still
    expected to be the broader complex over AR/TN maturing later into
    the evening. Given the gradual intensification/organization, the
    severe threat will continue to increase across much of WW322.
