The severe weather threat for Severe Thunderstorm Watch 143, 145
SUMMARY...Damaging winds remain possible across northwest Georgia as
an ongoing MCS continues to move east/southeast across the region.
DISCUSSION...An ongoing MCS continues to propagate to the
east/southeast across northwest GA. Regional VWPs and RAP
mesoanalysis suggest 0-3 km bulk shear vectors are generally between
20-35 knots and are mainly aligned along the MCS's long-axis.
However, a few meridional bulges in the line have been noted in
recent KFFC imagery, which will locally enhance the potential for
damaging winds as the outflow becomes more orthogonal to somewhat
strong low-level shear vectors. This MCS should continue to
propagate to the east/southeast over the next few hours and will
continue to pose a wind threat (particularly with any north-south
oriented bulges) as MLCAPE increases across central/eastern GA amid
partly cloudy skies and boundary-layer warming. Additional
development upstream across northern AL will likely move into
northern GA in the wake of the ongoing MCS later this afternoon and
may pose an additional risk for severe winds.
