...THERE IS A MARGINAL RISK OF SEVERE THUNDERSTORMS ACROSS SOUTHEAST STATES...

...SUMMARY...
Isolated severe thunderstorms are possible across parts of the
Southeast today into this evening. Damaging wind gusts, large hail,
and perhaps a tornado are the expected hazards.

...Southeast States...
Clustered bands of thunderstorms have increased across east-central
Mississippi and central Alabama into northwest/west-central Georgia
during the predawn hours. These elevated storms are occurring on the
immediate cool side of a front that is draped
west/southwest-east/northeast across the region. These storms may
further increase and organize early today. The aggregating storm
mode and residually warm mid-level temperatures/modest mid-level
lapse rates should tend to temper hail potential. However, the
storms may become surface-based with time owing to diurnal heating
cycle and potential gradual cold pool-related storm propagation
toward the warm/moist side of the front where upper 60s F surface
dewpoints will persist through peak boundary layer mixing. This
scenario will potentially contribute to damaging wind potential into
late morning, and more so this afternoon across southeast Alabama
into southwest/south-central Georgia. Additional strong/severe storm
development may occur farther west later this afternoon across a
broader part of far southern Alabama/Florida Panhandle near the front.

Low-level shear is initially strong but low-level flow is veered
west-southwesterly and will tend to weaken over time. Regardless,
long semi-unidirectional hodographs, particularly above 2.5 km AGL,
will persist with 50+ kt effective shear. This will support
organized storm modes potentially including bowing segments and
possibly a couple of splitting supercells.

Overall, damaging winds and hail are expected to be the primary
hazards, with some tornado potential as well, albeit relatively
limited and dependent on warm-sector development. While short-term
uncertainties exist regarding the magnitude of today's severe risk,
areas such as southeast Alabama and southwest/south-central Georgia
will be closely reevaluated in subsequent outlooks for a possible
categorical Slight Risk upgrade, mainly for damaging wind potential.
