....NO SEVERE THUNDERSTORM AREAS FORECAST...

....SUMMARY...
A few thunderstorms are possible Saturday into Saturday night
across parts of the Southeast, as well as portions of the Colorado
Rockies and adjacent central Plains.

....Synopsis and Discussion...
A cool and dry continental air mass will be in place across much of
the central and eastern CONUS early Saturday, with any low-level
moisture confined to the immediate Gulf Coast and FL. A surface low
will likely be over southeast LA Saturday morning, on the western
edge of a stalled front that extends from the low northeastward
through far northern FL. This low is forecast to progress gradually
eastward throughout the day, as a weak shortwave trough moves from
east TX across the Lower MS Valley and Southeast. Showers and
thunderstorms will likely be ongoing near this low early Saturday,
with at least isolated thunderstorms anticipated throughout the day
as the low moves eastward. Some localized enhancement of the
low-level flow is possible in the vicinity of the low, but the
strongest shear and better low-level moisture/buoyancy are expected
to stay offshore, mitigating the severe potential.

Farther west, lee troughing is anticipated across the central and
southern High Plains ahead of a shortwave trough moving through the
Intermountain West and Rockies and into the Plains. Moisture return
will be limited ahead of this shortwave, but a few lightning flashes
could result from the high terrain in CO into the central Plains
where modest mid-level moistening and cold temperatures aloft may
result in limited buoyancy.
