.DISCUSSION...FOR EXTREME SOUTHWESTERN CALIFORNIA INCLUDING ORANGE...
SAN DIEGO...WESTERN RIVERSIDE AND SOUTHWESTERN SAN BERNARDINO
COUNTIES...

Weak troughing will linger over the US West Coast into tomorrow,
maintaining onshore flow, near to slightly below average
temperatures, and elevated winds through passes and locally into
the deserts. Peak wind gusts this afternoon will be 35 to 40 mph,
locally up to 50 mph through the San Gorgonio pass. Winds will
weaken as the trough moves north and east Tuesday, allowing for
heights to rise and conditions to begin to warm. Highs on Tuesday
are forecast to be a few degrees above average for inland
locations and 4 to 8 degrees above average for the coast.

Ridging aloft will take the place of the aforementioned troughing
for the middle to end of the week. The main axis of the ridge will
remain over the Pacific Ocean but the periphery of it will be over
the US West Coast. This will result in a warming trend for the
middle to end of the week. Warmest conditions will likely be
Thursday through Saturday, with highs 6 to 12 degrees above average.
Areas of moderate HeatRisk are expected for the Inland Empire and
the deserts.

With the predominately onshore flow, the marine layer will stay on
the deeper side into tomorrow morning, which will push low clouds
into the valleys. Starting Tuesday, the marine layer is expected
to become shallower as heights start to rise. By the end of the
week, low clouds and fog are only expected along the coast.
