MD 0661 CONCERNING TORNADO WATCH 187... FOR SOUTHEASTERN MISSISSIPPI INTO CENTRAL/SOUTHERN ALABAMA Mesoscale Discussion 0661 NWS Storm Prediction Center Norman OK 0813 PM CDT Wed May 06 2026 Areas affected...southeastern Mississippi into central/southern Alabama Concerning...Tornado Watch 187... Valid 070113Z - 070315Z The severe weather threat for Tornado Watch 187 continues. SUMMARY...Threat for large hail and tornadoes continues within WW186 and WW187. DISCUSSION...Along and south of the cold front in central Alabama, supercells have produced large to very large hail (up to 2.75 inches). This threat will likely continue over the next couple of hours, given strong deep layer shear and MLCAPE around 1000-1500 J/kg. The increase of the LLJ has been noted across southern Mississippi over the last couple of hours, with notable increase in supercell intensity. Guidance suggests that through time, the 40-50 kt LLJ will increase and move northeastward into southern Alabama over the next several hours. Mature supercells coming out of Mississippi may continue to pose a risk for tornadoes into Alabama as a result. Cells along the front may tend to grow upscale into clusters but will still pose some risk for line embedded circulations and potentially tornadoes. ..Thornton.. 05/07/2026 ...Please see www.spc.noaa.gov for graphic product...
