However, the severe threat should be sparse and a WW issuance is not expected. DISCUSSION...A QLCS continues to progress east across portions of southern KY into middle TN. However, low-level moisture and overall buoyancy are struggling to overspread far southeastern parts of KY into eastern TN, limiting the severe threat. As the axis of a LLJ overspreads the central Appalachians, strong deep-layer and low-level shear should result. The strong low-level shear suggests that a damaging gust or tornado could occur if a storm or line segment could ingest any surface-based, unstable air parcels. Nonetheless, the limited low-level moisture amid a cooling boundary layer suggests that ingesting surface-based, buoyant parcels will be challenging, so the severe threat should be sparse at best. As such, a WW issuance is not currently anticipated. ..Squitieri/Goss.. 12/10/2023 ...Please see www.spc.noaa.gov for graphic product... ATTN...WFO...RLX...MRX...JKL...
