...Discussion from Los Angeles/Oxnard...


A weak upper level trough of low pressure will evolve into a  cutoff
low pressure system moving across Central California on Friday. This
will maintain strong onshore flow and a deep marine layer pattern,
with low clouds and fog reaching the coastal slopes each night and
morning. This pattern will maintain cool temperatures and high
humidities from the mountains to the coast. Gusty onshore winds will
continue across the Los Angeles county mountains and Antelope Valley
through Friday, with gusts generally in the 35 to 45 mph range each
afternoon and evening, except isolated gusts up to 50 mph near Lake
Palmdale. Increasing sundowner winds are expected over southern
Santa Barbara County Friday evening and continuing through the
weekend, strongest in the late afternoon and evening hours.


...Discussion from Monterey...

An upper level low pressure system off the California coast will
move slowly inland across central California late in the week. This
low will maintain unseasonably cool conditions across inland areas
through Friday and also produce  shower chances across the district
from late Thursday through  early Saturday. Although thunderstorms
are not currently forecast  to occur, they can`t be ruled out
entirely, especially on Thursday   night and Friday morning. Drier
and warmer conditions are expected from midday Saturday through the
rest of the holiday weekend.

Note : All winds are 20-foot Winds Unless otherwise specified.
Thunderstorms imply strong, gusty and erratic winds.
