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

...Gusty northwest to north winds will bring elevated fire danger
today into tonight for portions of Southwest California...

...Gusty north winds with warming and drying trend will bring
elevated fire danger to much of Southwest California on
Saturday...with critical conditions possible in the mountains...

...Gusty Santa Ana winds with hot and dry conditions will bring
elevated to critical fire weather conditions to Southwest California
Sunday through Tuesday...

A weakening cold front will bring isolated showers and drizzle to
portions of Southwest California this morning. The main impact will
be increasing northwest to north winds behind the front which will
bring elevated fire danger to many areas today through tonight. The
strongest winds today through tonight will be focused across the
mountains, Antelope Valley, Central Coast, and Santa Barbara County
south coast where gusts between 40 and 55 mph will be common.
Humidites are not expected to be sufficiently low during this time
to warrant any Red Flag Warnings, however a drying trend will
beginning to occur across downslope portions of the mountains
overnight.

Northerly flow on Saturday and Saturday night is expected to bring a
warming and drying trend along with elevated fire danger to the
region. The strongest winds during this period will remain focused
across the mountains, especially the Interstate 5 corridor and Santa
Ynez mountains where gusts between 40 and 50 mph can be expected. A
Fire Weather Watch is in effect for the mountains beginning Saturday
morning and will likely be converted to a Red Flag Warning later
today.

From Sunday through Tuesday, there is the potential for a prolonged
duration of gusty Santa Ana winds with hot and very dry conditions.
The strongest Santa Ana winds during this period is expected to be
Monday through Tuesday when gusts between 40 and 50 mph will be
possible across wind prone passes and canyons of Los Angeles and
Ventura counties. Record breaking triple digit heat and humidities
lowering into the single digits and lower teens will be possible
during this time. In addition, very warm and dry conditions during
the overnight hours in the mountains, foothills, and wind prone
areas will add to this fire weather threat during this long duration
of dangerous fire weather conditions. A Fire Weather Watch is in
effect for all mountain and  valley areas of Los Angeles and Ventura
counties Sunday through Tuesday, and may need to be expanded into
coastal areas as we draw closer to the event.


...Discussion from Monterey...

Overnight cold front brought measurable and even wetting rains to
much of the district. Rainfall exiting to the southeast this
morning. Breezy northwest winds and cooler conditions expected today
behind the front. Significant warming  and drying trend starts
Saturday and lasts into next week as  strong high pressure rebuilds
and weak offshore flow develops.

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