    Areas affected...Western Tennessee...northern Mississippi...northern
    Alabama

    Concerning...Severe Thunderstorm Watch 135...136...

    Valid 102208Z - 110015Z

    The severe weather threat for Severe Thunderstorm Watch 135, 136
    continues.

    SUMMARY...Severe wind gusts and large hail are expected with
    convection as it spreads southeast this evening.

    DISCUSSION...Mid-level heights are falling across the Mid South this
    evening as a 500mb speed max digs across eastern KS toward northern
    MS. Left-exit region of this jet appears partly responsible for an
    expanding cluster of thunderstorms along the cold front over western
    TN. Additionally, while the boundary-layer lapse rates are quite
    steep across much of this region, surface temperatures are
    considerably warmer across northern MS into central AL where
    readings are in the lower 80s. As profiles cool aloft, the greatest
    buoyancy should focus across northern MS into northern AL. Frontal
    convection may continue to grow upscale due to the aforementioned
    exit region and thermodynamic profiles favor strong downdrafts, in
    addition to large hail. Severe storms should spread across northern
    MS and northern AL through mid evening.
