141 ACUS11 KWNS 181753 SWOMCD SPC MCD 181752 NCZ000-SCZ000-GAZ000-TNZ000-181945- Mesoscale Discussion 1677 NWS Storm Prediction Center Norman OK 1252 PM CDT Thu Jul 18 2024 Areas affected...Northern Georgia into eastern South Carolina Concerning...Severe potential...Watch unlikely Valid 181752Z - 181945Z Probability of Watch Issuance...20 percent SUMMARY...Isolated reports of damaging winds are possible across northern Georgia into eastern South Carolina and portions of southwestern North Carolina. DISCUSSION...Thunderstorm coverage has increased across portions of northern Georgia, southwestern North Carolina, and eastern South Carolina, as convective temperature has been reached across much of the area. Precipitable water values approaching the 90th percentile for the region, coupled with meager vertical shear of only 20 kts, will result in a localized threat for water loaded updrafts collapsing into downbursts capable of severe winds. Overall convective organization is expected to remain low, though some loosely organized bowing convective segments are possible where outflow interactions are favorable. This convective activity will then diminish after sunset. ..Halbert/Squitieri/Hart.. 07/18/2024 ...Please see www.spc.noaa.gov for graphic product... ATTN...WFO...CAE...GSP...MRX...FFC...
