Day 2 Convective Outlook

Valid 101200Z - 111200Z

....THERE IS A MARGINAL RISK OF SEVERE THUNDERSTORMS NEAR THE CENTRAL
AND SOUTHERN CALIFORNIA COAST AND ADJACENT COASTAL MOUNTAINS...

....SUMMARY...
Isolated strong to severe thunderstorms capable of producing
damaging winds and perhaps a brief tornado may occur Tuesday across
parts of southern/central California.

....CA...
A potent mid-level shortwave trough will move ashore the CA coast
during the day with this feature moving to the Four Corners by
daybreak Wednesday.  Mid-level cold air advection accompanying the
trough will act to weakly destabilize the airmass primarily in the
vicinity of the central and southern CA coast and adjacent
mountains.  A plume of deep-layer moisture from the eastern Pacific
will favor scattered to widespread showers and isolated
thunderstorms from the coast to areas farther inland (i.e., Mojave
Desert and southern Great Basin).  Forecast soundings near the coast
show weak buoyancy with a strong wind profile featuring veering flow
strengthening with height.  A few weak, transient embedded cells
near the central-southern CA coast may exhibit episodic weak
rotation, and perhaps be capable of a localized risk for wind damage
or a brief/weak tornado during the day.
