Mesoscale Discussion 0853
NWS Storm Prediction Center Norman OK
1223 PM CDT Mon May 25 2026
Areas affected...portions of the northern Gulf Coast and Southeast
Concerning...Severe potential...Watch unlikely
Valid 251723Z - 251930Z
Probability of Watch Issuance...5 percent
SUMMARY...Scattered to numerous thunderstorms this afternoon may
pose a sporadic risk for strong wind gusts. Little in the way of
storm organization is expected.
DISCUSSION...As of 1715 UTC, visible and radar imagery showed a
broad area of thunderstorms ongoing over the central Gulf Coast
states associated with a remnant MCV. Widespread anvil debris
remains apparent and should limit destabilization over much of MS,
western AL and the western FL Panhandle. To the east of the MCV and
clouds, strong diurnal heating is rapidly destabilizing the air mass
across eastern AL, northern FL and much of GA and into SC. Despite
the poor mid-level lapse rates, 70s F surface dewpoints are
supporting ~2000 J/kg of MLCAPE. Sufficient for periodic stronger
updrafts, scattered to numerous thunderstorms are expected this
afternoon and evening as convective temperatures in the mid to upper
80s F are breached.
While some low and mid-level flow enhancement is occurring closer to
the MCV farther west, little in the way of vertical shear is present
over much of the Southeast (EBWD <25 kts). This suggests storm
organization will be quite limited, with a predominant pulse/multi
cell storm mode. High PWAT content (greater than 2 inches) may
support a few stronger downdrafts capable of sporadic damaging
gusts.
Storm coverage should increase this afternoon, along the eastern
edge of the remnant cloud shield and differential heating zone in
AL/GA, and in association with sea breeze convection in northern FL.
A few stronger clusters may evolve as outflows consolidate. However,
the lack of border upper air support should limit a sustained
severe threat and a watch appears unlikely.
