Mesoscale Discussion 1590 NWS Storm Prediction Center Norman OK 0314 PM CDT Sat Jul 11 2026 Areas affected...portions of coastal South Carolina into Cape Fear...North Carolina Concerning...Severe Thunderstorm Watch 481... Valid 112014Z - 112145Z The severe weather threat for Severe Thunderstorm Watch 481 continues. SUMMARY...Scattered strong to severe thunderstorms continue to pose a risk for damaging wind gusts across portions of coastal South Carolina and the Cape Fear vicinity in North Carolina. DISCUSSION...Loosely organized thunderstorms have progressed east-southeastward across much of central South Carolina over the past several hours, producing scattered reports of damaging wind gusts and a few measured gusts around 40 kts. The environment downstream of these storms remains favorable for damaging wind gusts, with temperatures noted in the mid-90s F along with MLCAPE of 1500 J/kg and steep low-level lapse rates of 7.5-8.0+ C/km. Current track extrapolation indicates these storms should progress offshore within the next 1-2 hours, bringing an end to the severe threat across the coastal Carolinas. ..Chalmers.. 07/11/2026 ...Please see www.spc.noaa.gov for graphic product...
