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

Isolated thunderstorms are a possible each afternoon through Monday,
focused across the mountains, mainly for Ventura  and Santa Barbara
Counties. The main concern with any thunderstorms that form is the
potential for fire starts from lightning,  especially with the dry
fuels in place. Elevated fire weather  conditions are possible late
Monday into Tuesday across the Los  Angeles County Mountains as
humidities fall well into the teens with  southeasterly winds gust
up to around 30 mph.

Onshore flow will gradually weaken through the week as a weak trough
 aloft is gradually replaced by a weak ridge. This will support
gradual warming for the first half of the week with more significant
 warming possible later in the week. The warmer temperatures
combined  with a receding marine layer will also support an overall
drying  trend away from the coast.


...Discussion from Monterey...

Seasonal conditions will continue throughout the Bay Area and
Monterey Bay region this week. Min RH is expected to remain
moderate, in conjunction with locally gusty winds, along the mid
slopes and peaks through the middle of the week. Overnight
recoveries are forecast to remain strong. Temperatures should
remain seasonal. By late week a slight warming and drying trend is
expected to develop as high pressure builds over the area.

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