Valid 241200Z - 251200Z

...NO SEVERE THUNDERSTORM AREAS FORECAST...

...SUMMARY...
Isolated weak thunderstorms will be possible on Saturday and
Saturday night across portions of eastern Texas into Louisiana and
southern Mississippi.

...Synopsis...

An arctic cold front will continue to develop southeast across the
western and central Gulf Coast vicinity on Saturday. Warm advection
atop the boundary and cooling aloft will support modest instability.
Isolated to widely scattered thunderstorms will be possible in the
vicinity of the front from the Upper Texas Coast into southern LA.
Some thunderstorm potential may even accompany convective elements
within wintry precipitation to the cold side of the surface front.
Severe storms are not expected.

Day 4-8 Convective Outlook

...DISCUSSION...
A surface low over the Deep South on Day 4/Sunday morning will
develop east/northeast through early Monday, moving offshore the
Carolinas coast. As this occurs, an arctic cold front will continue
to push southeast across the Southeast U.S. Ahead of the front,
modified Gulf moisture will be in place, supporting weak
instability. As an upper trough approaches, large-scale ascent and
warm advection atop the surface front will support isolated
thunderstorms across southern MS/AL into northern FL and southern
GA. Modest instability and poor lapse rates should limit severe
potential within the warm sector.

By Day 5/Monday, the cold front will have moved well offshore the
Gulf and Atlantic coasts and an arctic airmass will envelop much of
the CONUS. Mean troughing is forecast to persist, allowing
reinforcing shots of colder air to filter southward east of the
Rockies and preclude any return flow across the Gulf basin.
