   The severe weather threat for Tornado Watch 216, 217 continues.

   SUMMARY...Leading convective line across the Savannah Valley may
   necessitate an additional downstream watch issuance into the coastal
   plain of South Carolina and Georgia in the near-term. Greater severe
   potential is expected to evolve from upstream clusters and lines
   shifting east-southeast from eastern Alabama, with likely watch
   issuance into south Georgia.

   DISCUSSION...A leading line of storms across parts of the Savannah
   Valley into the SC Midlands has struggled to intensify with measured
   gusts holding below 30 mph. However, full boundary-layer heating is
   underway downstream to the coast. This coupled with a favorable low
   to deep-layer shear environment per CAE VWP data will support
   probable intensification of this line as it approaches the coastal
   plain through early afternoon. An increase in damaging wind
   potential, as well as brief embedded tornadoes may occur.

   More prominent severe potential should emanate out of initially
   semi-discrete supercells across parts of south AL spreading east of
   the Chattahoochee River into GA, as well as an organized linear
   cluster moving southeast from east-central AL. It appears likely
   that further upscale growth will occur into this afternoon, yielding
   a broader linear cluster/QLCS pushing southeast across much of
   central and south GA.
