...NO SEVERE THUNDERSTORM AREAS FORECAST...

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

...DISCUSSION...
An upper-level low will move east-northeastward from near the
central coast of California into the Intermountain West on Monday. A
trough extending southwestward from the low will approach the coast
of southern California during the afternoon. Thunderstorm
development will be possible within a plume of mid-level moisture
associated with the trough. The chance for lightning will gradually
increase southeastward along the coast from Santa Barbara into the
Los Angeles vicinity during the day. Instability will be weak which
will limit any severe potential. Elsewhere across the continental
United States, thunderstorm development is not expected Monday or
Monday night.
