034 ACUS11 KWNS 270918 SWOMCD SPC MCD 270917 NCZ000-SCZ000-GAZ000-271115- Mesoscale Discussion 2123 NWS Storm Prediction Center Norman OK 0417 AM CDT Fri Sep 27 2024 Areas affected...Eastern Georgia...South Carolina...Southern North Carolina Concerning...Tornado Watch 686...687... Valid 270917Z - 271115Z The severe weather threat for Tornado Watch 686, 687 continues. SUMMARY...A tornado threat will continue tonight from eastern Georgia into South Carolina and southern North Carolina. DISCUSSION...Tropical Storm Helene is currently moving northward through east-central Georgia. Mosaic radar imagery shows that rainbands extend outward up to 200 statute miles to the north of Helene. Within these rainbands, several discrete cells are ongoing across eastern South Carolina, where the tornado threat is maximized at this time. The WSR-88D VWP at Wilmington, North Carolina appears representative of the environment from the middle South Carolina coast northward to Wilmington, and has 0-6 km shear near 50 knots with 0-3 km storm-relative helicity in the 400 to 500 m2/s2 range. This will continue to support a tornado threat as thunderstorms move north-northwestward across South Carolina over the next several hours. The tornado threat should gradually move northward into southern and central North Carolina. ..Broyles.. 09/27/2024 ...Please see www.spc.noaa.gov for graphic product...
