Valid 211200Z - 221200Z

...NO SEVERE THUNDERSTORM AREAS FORECAST...

...SUMMARY...
Severe-thunderstorm potential is expected to be low on Sunday.

...Synopsis...

A weak mid/upper flow regime will persist with upper ridging over
the West and upper troughing over the eastern two-thirds of the
CONUS. A seasonally moist and unstable airmass will envelop the
south-central and southeast states into the Mid-Atlantic, and less
moisture with northward extent across much of the eastern Plains
into the Midwest. Widespread thunderstorm activity is expected from
the southern/central Rockies into the Plains, Southeast and
Mid-Atlantic. A few areas of convectively enhanced vorticity maxima
may float through southwesterly flow over the Southeast to the
Carolinas, and in northwesterly flow from the central/southern High
Plains into OK/TX. Pockets of moderate destabilization will be
rather widespread across the vast warm sector east of the Rockies.
Sporadic strong storms producing gusty to locally damaging winds are
possible across the central/southern Plains vicinity eastward across
the southern tier of the U.S. Poor midlevel lapse rates and weak
vertical shear, along with a lack of large-scale ascent, will
preclude focused areas of organized severe convection.
