Isolated damaging winds and perhaps a tornado remain possible tonight across portions of the southeastern US. ...01z Update... Primary upper low is shifting northeast toward southern WI early this evening as main midlevel jet translates across the TN Valley. With the upper system now focused over the Great Lakes, trailing cold front is less dynamically focused but should still remain the primary mechanism for convective development this evening. 00z soundings ahead of the front exhibit around 6.5-7C/km midlevel lapse rates at JAX/CHS, but notably weaker over the FL Peninsula where surface-based parcels are less inhibited. Latest radar data suggests the strongest updrafts should continue along the southern influence of the upper trough where surface-based buoyancy supports robust updrafts -- namely southern GA northern FL. Even so, most of this activity has not produced severe wind/hail and any supercell structures are notably weak. Even so, strong shear will continue to support the potential for robust updrafts, though boundary-layer recovery may struggle to reach levels necessary for widespread, organized updrafts. ..Darrow.. 01/13/2024 Read more View the full article Quote
