Administrators NorthGeorgiaWX Posted December 9, 2023 Administrators Share Posted December 9, 2023 MD 2306 CONCERNING SEVERE POTENTIAL...WATCH LIKELY FOR NORTHERN AL INTO MIDDLE/EASTERN TN AND EASTERN KY Mesoscale Discussion 2306 NWS Storm Prediction Center Norman OK 0245 PM CST Sat Dec 09 2023 Areas affected...Northern AL into middle/eastern TN and eastern KY Concerning...Severe potential...Watch likely Valid 092045Z - 092215Z Probability of Watch Issuance...80 percent SUMMARY...The severe threat will increase as storms approach from the west. Tornado Watch issuance is likely by 3-4 PM CST. DISCUSSION...A broken line of supercells is currently ongoing from southern KY into western TN and northwest MS. While instability is currently quite limited from eastern TN into southeast KY, some moistening/destabilization is expected with time through late afternoon, aided by rather strong southwesterly low-level flow above the surface. With longer-lived supercells already ongoing, organized convection may spread eastward even as the environment becomes somewhat less favorable, with a continued threat of a couple tornadoes and locally damaging wind. In addition to ongoing convection, additional development is possible ahead of the approaching cold front across parts of northern AL into southern middle TN, as a low-level warm advection regime gradually increases into this evening. Supercells may evolve out of this activity as well, with an attendant threat of all severe hazards. Given the concerns described above, Tornado Watch issuance is likely for parts of the region by 3-4 PM CST. ..Dean/Guyer.. 12/09/2023 ...Please see www.spc.noaa.gov for graphic product...
