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

....SUMMARY...
Severe thunderstorms appear unlikely on Tuesday.

....Synopsis and Discussion...
A pronounced upper trough with associated 80-100+ kt mid-level jet
should move quickly eastward over the western CONUS on Tuesday. A
band of low-topped thunderstorms may be ongoing early Tuesday
morning along/near the central CA Coast. This activity should
generally weaken through the morning hours as it advances inland and
encounters a hostile thermodynamic environment. Otherwise, isolated
lighting flashes appear possible across much of CA and into parts of
the southern Great Basin Tuesday, as strong large-scale ascent
attendant to the upper trough combines with weak elevated
instability to support charge separation in updrafts. Even though
deep-layer shear will be strong, the potential for organized severe
thunderstorms across the southern San Joaquin Valley and southern CA
should be hampered by minimal instability inland due mainly to the
poor timing of the upper trough prior to the diurnal heating cycle.
