…Gulf States/Tennessee Valley…

Positive-tilt trough continues to settle southeast with attendant height falls evident across the Mid-South/OH Valley region. In response to this feature, considerable amount of convection has developed within a 50-100 mi corridor from southern LA – central MS – northern AL – middle TN. Numerous long-lived supercells, some tornadic, have been noted within this corridor but recent trends suggest a more linear mode evolving, especially north of I-20. Over the last hour or so, more discrete supercells have congregated farther south across southern MS where greater buoyancy resides. Latest radar data suggests several long-lived supercells will track across southeastern portions of ww701 into west-central AL. This cluster of storms will necessitate focusing the highest severe probs along this corridor. Tornadoes remain possible with these storms. Have opted to increase severe probs a bit into western portions of GA to account for this activity maintaining some intensity toward the end of the period.

Farther north, well-defined bow-type squall line has evolved along the TN/AL border moving east at roughly 45kt. While an embedded tornado can not be ruled out with this organized bow, the primary severe threat should be winds.
