Valid 111200Z - 121200Z

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

....SUMMARY...
Severe weather is not expected across the U.S. Sunday.

...Discussion..
As a large upper trough/low moves onshore, and begins moving
southeastward across the western U.S. Sunday, evolution into a
closed low is expected.  Showers -- and possibly some embedded
lighting at times -- will spread across portions of California and
Nevada, and possibly as far southeastward as the Grand Canyon
region.

Meanwhile, a weaker wave is forecast to continue moving
east-southeastward, crossing the Lower Mississippi Valley during the
day, and then continuing into the Southeast.  Showers and a few
thunderstorms will also accompany this feature, from portions of
southern and eastern Texas eastward to Georgia.  However,
instability should remain very weak, precluding any appreciable
severe potential.

Elsewhere, thunderstorms are not expected across the U.S. through
Monday morning.

...Goss.. 12/10/2022
