A couple of damaging gusts and perhaps a tornado cannot be ruled out into the early overnight hours. DISCUSSION...Though surface temperatures have been gradually lowering with the onset of nocturnal cooling, low-level moisture continues to gradually increase with ongoing warm-air advection. Coincidentally, an increase in low-level shear has been noted as a 40 kt 850 mb jet overspreads eastern Kentucky, contributing to enlarging/elongating hodographs. However, the nocturnal cooling is also contributing to stabilization of the boundary layer, lowering the confidence in effective ingestion of the more favorable SRH. At the moment, the severe threat is expected to be isolated at best. Nonetheless, the presence of an impressively sheared environment suggests that a couple of damaging gusts or a tornado could manifest from any storms that ingest surface-based parcels, even for brief periods of time. As such, a WW issuance appears unlikely, though conditions will continue to be monitored. ..Squitieri/Goss.. 12/09/2023 ...Please see www.spc.noaa.gov for graphic product...
