Valid 281200Z - 291200Z

...NO SEVERE THUNDERSTORM AREAS FORECAST...

...SUMMARY...
Severe thunderstorms are not forecast across the U.S. on Monday or
Monday night.

...DISCUSSION...
At mid-levels, a ridge will be in place over the central U.S. on
Monday, as a trough moves into the Desert Southwest. Between these
two features, moisture and instability will be sufficient for
scattered thunderstorm development from parts of the Desert
Southwest and Intermountain West eastward into the Great Plains.
Instability is forecast to remain relatively weak, and severe
thunderstorms are not forecast across the continental U.S. Monday or
Monday night.
