...NO SEVERE THUNDERSTORM AREAS FORECAST...

...SUMMARY...
Isolated thunderstorms will be possible on Monday along the coast of
California but no severe threat is expected.

...DISCUSSION...
An upper-level low will move eastward into the Intermountain West on
Monday. To the south of the low, an upper-level trough will approach
the southern California coast during the day. Strong large-scale
ascent within a plume of mid-level moisture will support isolated
thunderstorm development along the central and southern California
coast. Instability will be insufficient for a severe threat.
Elsewhere, thunderstorms are not forecast across the continental
United States.
