COUNTIES...

...Updated aviation section for 06Z TAF package...

Low clouds in the coastal basin are making their retreat to the
coast with clearing skies behind and to the east of the mountains.
Clearing at the coast will be short lived with the marine layer
expected to move back in later this afternoon and once again
filling into the coastal basin late tonight into the early Monday
morning. High temperatures will be near to just below the seasonal
average as an upper level low moves from just off the coast and
to the east Monday.

As low pressure decreases at the surface through Thursday,
temperatures will continue to cool and the marine layer will deepen.
This will increase chances for patchy drizzle west of the mountains
beginning Monday night through Thursday morning and bring daily
highs 10-15 degrees below average for the Inland Empire, mountain
areas, and deserts by Thursday afternoon.

An upper level trough is expected to slide down the coast Tuesday
through Thursday before moving out to the northeast Friday. This
trough will produce gusty onshore winds in the mountains and
deserts, especially in the desert mountain slopes and passes. The
strongest winds are expected Tuesday and Wednesday in the afternoons
evenings with wind gusts around 35-55 mph in desert areas, with
isolated gusts up to 60 mph through the passes.

Temperatures will begin to increase Friday, reaching near the
seasonal average by the weekend.
