...Showers and thunderstorms will develop over parts of the
Western/Central Gulf Coast...

...An overall tranquil Thanksgiving on the way with widespread
above-average temperatures east of the Rockies...

A front extending from the Lower Great Lakes roughly southwestward to the
Central Gulf Coast will move off the Northeast/Northern Mid-Atlantic Coast
by Thanksgiving evening.  Showers and thunderstorms will develop along and
ahead of the boundary along the East and Gulf Coasts on Thanksgiving.  The
front will linger over the Southeast on Friday producing showers and
thunderstorms along and near the boundary.

Meanwhile, another boundary will move southward from the Central Rockies
to the Western/Central Gulf Coast by Friday.  The northern end of the
front will move off most of the East Coast by Saturday, while the western
end of the boundary lingers over the Western/Central Gulf Coast.  Moisture
from the Western Gulf of Mexico will overrun the front aiding in producing
showers and thunderstorms over the area through Saturday.  Areas of heavy
rain may accompany some of the thunderstorms.

In the meantime, upper-level energy over the Northwest will move
southeastward to the Southern High Plains by Saturday.  The energy will
aid in producing light rain and snow showers over parts of the Northwest
through Friday morning.  On Friday, the upper-level energy will aid in
producing snow showers over parts of the Southwest and Southern Rockies. 
The light snow will move to parts of the Southern High Plains by Saturday.
 Furthermore, moisture coming off the Pacific will move into the Pacific
Northwest overnight Friday into Saturday producing rain with snow
developing over the higher elevations early Saturday morning.
