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

...Elevated fire weather conditions through early this evening for  Los
Angeles and Ventura County Mountains into the Antelope Valley  due
to low humidities and breezy winds...

Elevated fire weather conditions will continue this  evening for the
Los Angeles and Ventura County Mountains into the  Antelope Valley
with humidities generally between 8 and 20 percent  during the day
and breezy winds with gusts locally up to 30 mph. A  few cumulus
build-ups have been observed across interior SLO county  into the
Santa Barbara Mountains, but the lack of available moisture  at
lower levels should prevent any thunderstorms from forming.

After a slight increase in onshore flow for Wednesday, onshore flow
will 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 late in the
week with gradually warming likely continuing early next week. As a
result, an extended heat wave is looking more likely starting this
weekend and possibly continuing into the middle or end of next week.
 The warmer temperatures combined with a receding marine layer will
also support overall drier conditions, most notable across the
valleys into the coastal foothills. There is also the potential for
weak to moderate northerly winds each night beginning as early as
Wednesday for Southwestern Santa Barbara County and the I-5 corridor
through the Grapevine.


...Discussion from Monterey...

Typical summer weather conditions will continue  this week. Locally
gusty winds are a possibility along mid slopes and peaks through the
middle of the week. Overnight recoveries  are expected to remain
good to very good. 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.
