   Areas affected...Northwest Georgia

   Concerning...Severe Thunderstorm Watch 143...145...

   Valid 041721Z - 041915Z

   The severe weather threat for Severe Thunderstorm Watch 143, 145
   continues.

   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.
