...GUSTY OFFSHORE WINDS AND LOW HUMIDITIES SUNDAY MORNING...

...CHANCE OF SHOWERS MONDAY AFTERNOON INTO TUESDAY WITH THE
POTENTIAL FOR MORE WIDESPREAD WETTING RAINS LATER NEXT WEEK...

Gusty northwest to north winds will continue through this evening,
with the strongest winds remaining over the mountains, Antelope
Valley, and Central Coast. The winds will shift to the northeast
late tonight into Sunday morning, when gusts between 30 and 40 mph
will be likely across passes and canyons of Los Angeles and Ventura
counties. During this time, humidities will lower to between 10 and
20 percent bringing brief elevated fire weather concerns. The flow
is expected to shift back to onshore Sunday afternoon into evening.

Another cold upper level low pressusre system is expected to drop
over the area late Monday into Tuesday. At this time, the system is
expected to have limited over-water trajectory, but will bring a
threat of showers to the region Monday afternoon into Tuesday.
Highest probabilities of rain with this event will be areas north of
Point Conception, the north facing mountain slopes, and eastern Los
Angeles county. Due to the showery nature of the system, rainfall
amounts are expected to be quite variable, ranging anywhere from
zero to two tenths of an inch, with isolated amounts up to one third
of an inch. If this system shifts a bit further west and develops a
more over-water trajectory, there is a slight chance of higher
rainfall amounts and  intensities. As a result, there is a slight
chance of brief and localized heavier showers Monday night into
Tuesday. At this time, there is only a 10 percent probability of any
heavier showers affecting the recent burn areas, including the
Thomas Fire burn scar. Snow levels are expected to fall to between
2500 and 3000 feet by late Monday night into Tuesday morning, with
the possibility of 1 to 3 inch accumulations in the mountains,
including Interstate 5 near the Grapevine. There is also the
possibility of snow showers in the Antelope Valley with this system,
especially in the foothills. There is a potential for a more
widespread rainfall event later next week, most likely in the
Thursday to Saturday time frame.


...Discussion from Monterey...

Another clear and cold night is expected tonight with lows dropping
to the upper 20s in the coldest interior valleys. Dry and slightly
warmer temperatures are expected  over the weekend. A storm system
will spread rain over the area late Sunday night or Monday with snow
above 2000-3000 feet.

Note : All winds are 20-foot Winds Unless otherwise specified.
