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

...Elevated fire danger likely Sunday through middle of next week week
across portions of Southwest California due to weak offshore  flow
with warmer and drier conditions...

An upper level low pressure system will deepen across the region
through Thursday, maintaining a deep marine layer pattern which is
expected to rise to over 5000 feet across the LA basin by Thursday
morning. As a result, low clouds and fog are expected to spread well
into the coastal slopes by Thursday morning, with drizzle and a
chance of light rain showers, especially Los Angeles county.  There
will be gusty southwest to northwest winds through Thursday evening,
especially across the mountains, Antelope Valley, and Santa Barbara
South Coast where gusts between 35 and 45 mph will be common.

For this weekend and into the middle of next week, the upper level
trough will move to the east while surface high pressure builds into
 the Great Basin. At this time, some locally gusty northeast winds
are expected across the usual northeast wind-prone areas. With this
week offshore flow, afternoon temperatures will exhibit a
significant warming trend Sunday through the middle of next week.
Relative humidity will fall into the teens across many areas each
afternoon with limited overnight recoveries away from the coast. As
a result, there will likely be elevated fire danger across the area
Sunday through the middle of next week.


...Discussion from Monterey...

A cold front will push through the area this evening with some
sprinkles or drizzle across the Bay Area. Thursday will be the
coolest day of the next week with easing northwest winds. High
pressure will begin to rebuild on Friday with light north winds and
seasonable temperatures. Noticeable warming and drying trend will
continue through the weekend and into early next week with periods
of moderate north winds and lowering humidity.

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