...Discussion from Monterey...

High pressure will build over the district beginning  today,
resulting in a noticeable warming and drying trend, mainly across
higher terrain and away from the coast. Hot, dry, and gusty onshore
winds each afternoon and evening will lead to elevated fire weather
conditions through at least Thursday. Conditions improving  Friday
and over the weekend as high pressure moves over the interior  west.

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



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

North to northeast winds of 20 to 30 mph with gusts up to 45 mph
across the interior mountains including the I-5 corridor will
continue to  diminish through the morning. High pressure will build
over the West  Coast through Wednesday before pushing east, but
remaining nearby near  New Mexico. This will likely shrink the
marine layer and allow the  warmest coastal valleys to approach
90 degrees Tuesday through Thursday. Over the mountains and interior
valleys, temperatures between 95 and  105 will become common with
humidities likely falling into the 10 to 20  percent range. While
the winds do not look strong, the combination of  hot and dry
conditions with typical breezy diurnal wind patterns will  lead to
an elevated risk for grass fires, especially in the interior  areas
such as Antelope Valley.

As the ridge breaks down over the region Thursday through Saturday,
onshore winds will likely increase with gusts of 25 to 40 mph
(locally  50 mph Antelope Valley Foothills) possible for interior
areas,  potentially extending the elevated fire risk for grass
fires. However,  cooling trends will support an increase in minimum
humidities, rising to 15 to 25 percent for the windier areas by
Thursday.

There is about a 10 percent chance of showers or isolated
thunderstorms focused across the mountains and deserts of Los
Angeles and Ventura  Counties sometime in the Thursday through
Sunday time frame.
