...Discussion from Monterey...

Warm and dry conditions through Friday. Gusty northwest winds
develop late Friday to Sunday, with gusts to 45-50 mph across the
ridgetops, along the coasts, and through gaps and passes. Winds will
veer to the north late Sunday and Monday, leading to some offshore
flow in the North Bay. This will reinforce a warming and drying
trend early next week, and result in lower relative humidities
across the interior, increasing fire weather concerns.

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



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

is  expected. Minimum humidities away from the coast will generally
stay in  the 20 to 40 percent range, except down to 12 to 25 percent
for the  Antelope Valley and the highest interior mountain peaks.
Humidities will be the driest today and the moistest on Saturday
through the weekend.  Areas of gusty northwest to southwest winds
will occur at times. Winds  will be the strongest Saturday and
Sunday, when gusts of 25 to 45 mph  will be common for the Antelope
Valley and foothills, and Santa Barbara  southwest coast.

Monday into mid-to-late next week, a warming a drying trend is
expected, with temperatures rising to 85 to 95 degrees across the
valleys and deserts on Wednesday. Light offshore flow with mountain
gusts of 15 to 30 mph will be possible Monday and Tuesday, peaking
Tuesday. Expect relative humidities next week away from the coast to
be  in the 15 to 25 percent range, except for 8 to 15 percent across
