    Concerning...Severe Thunderstorm Watch 568...

    Valid 302036Z - 302200Z

    The severe weather threat for Severe Thunderstorm Watch 568
    continues.

    SUMMARY...Isolated cells may produce sporadic large hail to around
    1.5 inches in diameter over the next couple of hours. Local
    extensions of WW 568 are possible.

    DISCUSSION...A band of supercells has persisted across southeast IA
    in a modest warm advection regime atop a capped boundary-layer.
    Moderate instability exists downstream, along with favorable
    vertical shear. However, multiple rounds of convection have impacted
    parts of the area in the past 12 hours. This will likely preclude
    upscale development, though some hail and gusty wind risk may linger
    for a couple more hours. WW 568 is set to expire at 21z, though
    local watch extensions are possible.
