Mesoscale Discussion 2361 NWS Storm Prediction Center Norman OK 1104 AM CDT Sun Oct 11 2026 Areas affected...portions of central into northern North Carolina Concerning...Tornado Watch 680... Valid 111604Z - 111730Z The severe weather threat for Tornado Watch 680 continues. SUMMARY...A few tornadoes remain a concern over the next few hours. The best chance for tornadoes will be ahead of a surface low over central to northern NC. DISCUSSION...A band of organized thunderstorms are beginning to show slightly greater supercell characteristics as it advances eastward toward an instability axis, where favorable low-level shear is also present. Surface temperatures are warming into the upper 70s F, amid mid 70s F dewpoints, yielding over 1000 J/kg MLCAPE per 15Z mesoanalysis. Furthermore, the RAX VAD depicts an appreciable curved low-level hodograph, with over 250 m2/s2 0-3 km SRH, with nearly 150 m2/s2 contained in the lowest 500 m AGL. As such, a high-shear/moderate CAPE environment is present to support a continued isolated tornado threat. While a tornado is possible with any storm along the primary confluence band, the best chance for a tornado will be with the northern storms given their proximity to the surface low, and locally backed winds. ..Squitieri.. 10/11/2026 ...Please see www.spc.noaa.gov for graphic product...
