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

...Brief critical fire weather conditions likely this afternoon for
eastern foothills of the Antelope Valley into adjacent mountains...

Elevated fire weather conditions are expected for inland portions of
the mountains this afternoon and early evening due to gusty south to
southerly winds and low humidities. Brief critical fire conditions
are likely in wind prone areas of  the Antelope Valley foothills
into the adjacent mountains during this time. Humidities in this
area will likely drop to between 7 and 15  percent with peak
southerly winds gusting to around 35 mph. The other concern of the
day is further north into the Santa Barbara mountains into far
interior SLO County where an isolated thunderstorm or two  is
possible with fire starts due to any lightning being the greatest
concern there.

Onshore flow continue weaken through the week as a weak trough aloft
is gradually replaced by a moderate ridge. This will support gradual
warming for the first half of the week with more significant warming
becoming more likely late 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 excellent. 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.
