Watch issuance is possible. DISCUSSION...A loosely organized cluster of convection is ongoing this morning over southwestern TN and vicinity. While the boundary layer is only modestly unstable per 12Z BNA sounding and recent RAP forecast soundings over western TN, strong deep-layer shear associated with a pronounced mid/upper-level jet is present over the lower MS Valley into the TN Valley. Given the somewhat linear nature of the ongoing cluster, strong to damaging winds should be the main threat in the near term. But, the presence of a strong southwesterly low-level jet and effective SRH around 250-300 m2/s2 suggests that tornadoes will also be a concern with either line-embedded circulations, or with any supercells that can develop and persist. Trends will be closely monitored for possible watch issuance, pending signs of greater convective organization/intensity. ..Gleason/Thompson.. 04/02/2024 ...Please see www.spc.noaa.gov for graphic product...
