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).
