Mesoscale Discussion 1014 NWS Storm Prediction Center Norman OK 1241 PM CDT Mon May 27 2024 Areas affected...portions of southeast Alabama into central and southern Georgia...southern South Carolina Concerning...Severe potential...Watch likely Valid 271741Z - 271915Z Probability of Watch Issuance...80 percent SUMMARY...The severe threat will gradually increase into the afternoon. Large hail and damaging gusts are both a concern. A WW issuance will be needed in the next hour or so to address the severe threat. DISCUSSION...In addition to an ongoing supercell over western Georgia, thunderstorm development and intensification is underway over eastern AL. These storms are forming within an environment characterized by 80+ F surface temperatures and low to mid 70s F dewpoints, yielding 2000+ J/kg MLCAPE. Strong mid-level westerly flow is overspreading the region, contributing to 50+ kts of effective bulk shear. As such, multicell clusters and transient supercells should develop through the afternoon. Given steep low and mid-level lapse rates, these storms will be accompanied by severe hail and wind. A WW issuance will be needed in the next hour or so to address the impending severe threat. ..Squitieri/Guyer.. 05/27/2024 ...Please see www.spc.noaa.gov for graphic product...
