    Areas affected...Middle Tennessee and adjacent northern Alabama

    Concerning...Severe Thunderstorm Watch 141...

    The severe weather threat for Severe Thunderstorm Watch 141

    SUMMARY...Severe risk is focused across northern Middle Tennessee at
    this time, with downstream areas being monitored.

    DISCUSSION...Latest radar loop shows an organized band of
    thunderstorms -- and associated outflow -- moving eastward across
    Middle Tennessee, while outflow from storms across southern Kentucky
    moves southward. The most vigorous convection is ongoing near the
    intersection of these two outflow boundaries intersect -- i.e. over
    northern Middle Tennessee. An area of rotation within the broader
    band of convection continues, and is now over western Jackson
    county. While a brief tornadic spin-up remains possible here, and
    elsewhere along the leading edge of the convective band, potential
    for locally damaging winds will continue/shift eastward across WW
    141 this morning, through a favorably unstable/amply sheared
