Mesoscale Discussion 0984 NWS Storm Prediction Center Norman OK 0342 PM CDT Sun May 26 2024 Areas affected...portions of Middle into eastern Tennessee Concerning...Severe potential...Watch likely Valid 262042Z - 262145Z Probability of Watch Issuance...80 percent SUMMARY...The severe threat continues across portions of middle into eastern Tennessee. Large hail is becoming the main concern as storms become more supercellular through the afternoon. A couple of tornadoes also cannot be ruled out. Either a new WW issuance or local expansions of existing watches are needed. DISCUSSION...A line of thunderstorms has gradually transitioned to a more supercellular mode over the past couple of hours, with a dominant supercell recently producing severe hail. Other supercells are beginning to form in the warm sector as well, including in spots where the airmass remains pristine. Given ample buoyancy/shear and the more cellular mode, severe hail will become the main threat over Middle into eastern TN over the next few hours, though a couple of tornadoes and damaging gusts are still possible. As such, either a new WW issuance or expansion of existing watches is needed to address the present severe weather scenario. ..Squitieri/Bunting.. 05/26/2024 ...Please see www.spc.noaa.gov for graphic product...
