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

....SUMMARY...
Organized severe thunderstorms appear unlikely on Saturday.

....Synopsis...
A shortwave trough is expected to move from the central Plains
eastward through the Mid MS Valley and into the Lower OH Valley on
Saturday. Surface low associated with this shortwave is also
expected to move eastward, from its early period position over
eastern OK through the Mid-South. An attendant cold front will push
southeastward across central/east TX, southern AR, and western LA.
By early Sunday morning, this front is expected to extend from
western TN southwestward into deep south TX.

Modest moisture return will precede this front, with associated
buoyancy contributing to showers and thunderstorms as the front
moves southeastward. The stronger low to mid-level flow will be
displaced to the north of the warm sector, likely limiting storm
severity. Additionally, much of the thunderstorm activity should
occur behind the front. Even so, relatively cold mid-level
temperatures could still result in a few stronger storms capable of
hail, especially later in the period over the middle/upper TX coast
as another southern-stream shortwave trough approaches the region.

Farther west, a series of shortwave troughs will impact the West
Coast, including one early in the period across OR/northern CA and
another near the end of the period across northern and central CA. A
few lightning flashes a possible within the deeper convective cores
associated with these waves, particularly the second wave which has
colder mid-level temperatures and greater buoyancy associated with
it.
