The severe weather threat for Severe Thunderstorm Watch 108, 109
SUMMARY...Potential still exists for the evolution of another
upscale growing and organizing cluster of storms which could pose
increasing risk for damaging wind gusts across parts of southeastern
Alabama into southwestern Georgia through 7-9 PM EDT.
DISCUSSION...Lift aided by low-level convergence along a pre-cold
frontal wind shift advancing across southern Alabama, and warm
advection along a sharp, quasi-stationary, convectively reinforced
surface front across southwestern/southern Georgia, is maintaining
vigorous new thunderstorm development. This appears to be occurring
in the presence of moderate to large CAPE on the order of 1000-2000+
J/kg, and strong deep-layer shear beneath 50-70 kt
west-southwesterly flow around 500 mb. Low-level shear also remains
rather strong, with 40 kt southwesterly flow around 850 mb roughly
aligned with the wind shift.
Given this environment, the surface boundary intersection east of
Troy, AL into the Albany, GA vicinity might provide a focus for
consolidating, upscale growing convection during the next few hours.
If this occurs, the evolution of an organizing convective system
capable of producing damaging wind gusts could still evolve through
