Mesoscale Discussion 0728 NWS Storm Prediction Center Norman OK 0939 AM CDT Thu May 09 2024 Areas affected...central/eastern SC...central/south GA...southeast AL Concerning...Tornado Watch 216...217... Valid 091439Z - 091615Z 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. ..Grams.. 05/09/2024 ...Please see www.spc.noaa.gov for graphic product...
