...NO SEVERE THUNDERSTORM AREAS FORECAST...

...SUMMARY...
Severe thunderstorms are not currently expected on Sunday.

...Synopsis...
Within a broad, large-scale trough covering much of the
central/eastern CONUS, a low-amplitude shortwave is forecast to move
from the southern Great Plains into the Southeast on Sunday. In
response to this system, some low-level moisture return is possible
into parts of the upper TX coast and southern LA, in advance of an
approaching cold front. However, persistent surface ridging will
tend to keep the richer Gulf moisture mostly suppressed offshore.

Early-day elevated convection will be possible across parts of the
Gulf Coast, to the north of the primary baroclinic zone. Convective
showers may develop later in the day across parts of LA and southern
MS along/ahead of the approaching cold front, though forecast
soundings currently suggest that this convection may not be
sufficiently deep for lightning production.

Farther east, thermodynamic profiles may become at least marginally
supportive of thunderstorm development across parts of the FL
Peninsula and Keys. Isolated diurnal storm development cannot be
ruled out near any sea breeze boundaries and a remnant baroclinic
zone across the peninsula, though large-scale forcing will be
limited. Late in the period, thunderstorms over the Gulf may
approach parts of the FL Panhandle and Keys. While some increase in
deep-layer shear is possible with time, generally weak lapse rates
and modest buoyancy are currently expected to limit the
organized-severe threat.
