...Discussion from Monterey...

Seasonal to slightly below normal temperatures continue through the
weekend with the marine layer to deepen to around 2000 ft by
midweek. Excellent overnight humidity recoveries and poor to fair
daytime humidity retention continue for areas within the marine
layer. Localized elevated fire weather concerns continue for the
higher elevations above 2000 ft where poor to fair overnight
humidity recoveries and poor daytime humidity retention continue
through the end of this week. Persistent upper level troughing will
maintain light, onshore flow with diurnally breezy conditions
expected each afternoon/evening along the coast, mountain
gaps/passes, and along ridgetops.

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

...WIDESPREAD ELEVATED TO LOCALLY BRIEF CRITICAL FIRE WEATHER
CONDITIONS ACROSS THE INTERIOR VALLEYS, MOUNTAINS, AND DESERTS
THROUGH TUESDAY DUE TO GUSTY ONSHORE WINDS, VERY WARM TEMPERATURES,
AND LOW HUMIDITIES...

...SMALL RISK OF MONSOONAL THUNDERSTORMS THURSDAY THROUGH SUNDAY
ACROSS THE MOUNTAINS AND ANTELOPE VALLEY...

An upper level high pressure system over the region will continue to
bring very warm and dry conditions to far interior areas today. The
interior valleys, lower mountains, and deserts are seeing high
temperatures between 95 and 106 degrees today, with 5 to 7 degrees
of cooling likely by Tuesday and Wednesday. Meanwhile, minimum
humidity values will likely range between 10 and 20 percent in these
areas through Tuesday. The hottest and driest conditions will likely
be in the Antelope Valley during this period.  Strengthening onshore
flow has maintained marine layer low clouds across  coastal and
coastal valley areas, with a marine layer depth around 2000 feet.
Little change to this marine layer pattern is expected tonight, then
slight deepening is expected Tuesday night. This will maintain
benign weather conditions for coastal and coastal valley locations.

Gusty and widespread onshore winds are expected today through
Tuesday, with sustained winds of 15 to 30 mph and gusts of 30 to
45 mph common across the interior valleys, mountains, and deserts.
The strongest winds each day will mostly be focused during the
afternoon and evening hours, strongest across the Antelope Valley
and adjacent foothills extending through the Highway 14 corridor and
I-5 corridor, as well as the interior valleys of San Luis Obispo
County. The combination of strong onshore winds, very warm
temperatures, and low humidities will bring widespread elevated to
locally brief critical fire weather conditions across the interior
valleys, mountains, and deserts today through Tuesday, with the
highest probability of brief critical fire weather conditions in the
Antelope Valley.  As a result, there will be an increased risk of
large grass fires with rapid fire spread through Tuesday. There is
also a 10-15 percent chance of monsoonal showers and thunderstorms
over the mountains and deserts Thursday through Sunday.
