840 ACUS11 KWNS 272142 SWOMCD SPC MCD 272142 ALZ000-FLZ000-MSZ000-272345- Mesoscale Discussion 1022 NWS Storm Prediction Center Norman OK 0442 PM CDT Mon May 27 2024 Areas affected...Southern Alabama Concerning...Severe potential...Watch possible Valid 272142Z - 272345Z Probability of Watch Issuance...60 percent SUMMARY...A severe thunderstorm watch is being considered to address convection developing to the west of WW 334 into southern and southwest Alabama. DISCUSSION...Over the past hour, scattered thunderstorms have developed along a residual outflow boundary across south-central to southwest AL with bubbling cumulus noted in GOES visible imagery further west into southeast MS. This convection is developing just to the west of WW 334, but should mature in a similar thermodynamic/kinematic environment characterized by roughly 3000 J/kg MLCAPE and 35-45 knots of effective bulk wind shear. Storm motions and deep-layer shear vectors oriented along the boundary should favor upscale growth into clusters with time (with an increasing wind threat), but a large hail threat should manifest in the short term (next 1-2 hours). ..Moore/Smith.. 05/27/2024 ...Please see www.spc.noaa.gov for graphic product...
