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

....SUMMARY...
A severe threat is not expected to develop across the continental
U.S. through tonight.

....DISCUSSION...
The latest water vapor shows west-northwesterly flow over much of
the continental U.S., with a embedded shortwave trough in the
Southeast and another upper-level trough in the Northeast. Further
west across California, an upper-level trough over the far eastern
Pacific is approaching from the southwest. Ahead of the trough, flow
is southwesterly and divergent, with several bands of large-scale
ascent approaching the California coast.  As these bands of
large-scale ascent move inland this evening, isolated thunderstorms
will be possible across parts of central and northern California. A
lack of instability will make a severe threat unlikely. Elsewhere
across the continental U.S. thunderstorms are not expected through
tonight.
