...ELEVATED TO BRIEF CRITICAL FIRE WEATHER CONDITIONS THROUGH AT LEAST
TUESDAY OVER INTERIOR MOUNTAINS, DESERTS, AND VALLEYS DUE TO HOT AND
VERY DRY CONDITIONS WITH LOCALLY GUSTY ONSHORE WINDS AND POTENTIAL
VERTICAL PLUME GROWTH....

A strong upper level high pressure system centered over the four
corners area will continue to bring hot and very dry conditions to
interior sections of Southwest California through Tuesday. High
temperatures are expected to generally range between 95 and
105 degrees across the deserts, as well as warmer mountain and
interior valley locations. Minimum humidities will generally range
between 5 and 20 percent through Tuesday across interior valleys,
mountains, and deserts, with the driest air focused across the Los
Angeles county mountains and Antelope Valley. Some interior mountain
areas will also continue to experience very poor overnight humidity
recoveries remaining below 20 percent. Onshore winds gusting between
20 and 30 mph are expected across interior areas each afternoon and
evening, with local gusts up to 40 mph in the foothills of the
Antelope Valley. The combination of hot and very dry conditions with
moderate onshore winds will bring elevated to brief critical fire
weather conditions across all interior areas through Tuesday,
especially the Highway 14 corridor from Santa Clarita Valley to
Antelope Valley, and the Los Angeles county mountains. Any fire
ignitions during the afternoon hours across interior wind sheltered
areas  will also have the potential for significant vertical plume
growth, with peak mixing heights ranging between 10,000 and
15,000 feet through Tuesday.

There will also be weak and localized sundowner winds with warm and
dry conditions each evening through Wednesday across the western
canyons of the Santa Ynez mountains and Santa Barbara south coast,
with gusts generally in the 25 to 35 mph range (strongest near
Gaviota). There is expected to be a gradual cooling trend Wednesday
through Friday, followed by another potential warm-up over the
weekend.


...Discussion from Monterey...

A gradual inland cooling trend is forecast through much of the week
ahead. Overnight humidity recoveries will increase in the hills by
midweek as the marine layer deepens. Winds will remain light for the
most part, except for locally moderate and gusty onshore breezes
during the afternoon and evening hours. High clouds streaming in
from the south will  continue to move across the district through
Tuesday, and  possibly into Wednesday. High-based showers are
thunderstorms are not currently expected to develop from this
elevated moisture.

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