...NO SEVERE THUNDERSTORM AREAS FORECAST...

...SUMMARY...
Organized severe thunderstorms appear unlikely across the contiguous
United States on Saturday.

...Synopsis and Discussion...
A closed mid/upper-level low should move slowly eastward across the
southern Plains on Saturday. A prolonged period of precipitation
will likely have been ongoing since Friday across much of
central/east TX ahead of this feature, limiting instability. A weak
surface low is forecast to develop from the lower TX Coast vicinity
northeastward towards coastal LA through the period. A cold front
will probably move off the TX Coast Saturday morning, with elevated,
non-severe thunderstorms possible to its north across parts of
central/east TX. At this point, it appears that a marine warm front
extending east-northeastward from the surface low will not make
substantial progress inland across coastal LA/MS/AL through late
Saturday night. Accordingly, the potential for surface-based
thunderstorms posing even an isolated/marginal severe risk across
this area currently appears low.
