    Areas affected...portions of northern and eastern KY

    Concerning...Severe Thunderstorm Watch 136...

    Valid 311956Z - 312100Z

    The severe weather threat for Severe Thunderstorm Watch 136
    continues.

    SUMMARY...Strong to severe wind gusts will continue across severe
    thunderstorm watch 136 for another hour or two. Severe threat should
    lessen to the east and south of the watch area.

    DISCUSSION...The bow echo moving eastward across northern KY has
    produced severe gusts at SDF and FFT over the last hour. Additional thunderstorm clusters have developed southward into central KY,
    though are not exhibiting the fast forward propagation that original
    bowing segment possessed. The surging portions of the bow will
    continue eastward across the Bluegrass region. However, a relative
    minimum in instability exists across this region and points east due
    to earlier convection. Observed temperatures across this region have
    cooled into the upper 60s to low 70s and this should impede severe
    threat further east. In fact, latest 7km CAPPI shows decreasing
    reflectivity over the last hour or so. The cluster of storms further
    south in central KY may continue to pose a strong wind threat given
    steep low level lapse rates/higher DCAPE values. However, weak deep
    layer shear is likely limiting overall organization.
