... Unsettled weather expected across southwest California Friday
afternoon through Saturday...

A cold upper level trough of low pressure and surface cold front
will bring periods of rain... possible thunderstorms... some mountain
snow... and gusty winds to southwest California Friday afternoon
through Saturday.

A fast moving cold front will spread rain along the central coast by
midday Friday. The precipitation will move inland over San Luis
Obispo and Santa Barbara counties Friday afternoon... then southeast
across Ventura and Los Angeles counties through Friday evening.
Showers will persist into Saturday morning across the region... with
a chance of residual showers mainly on north facing mountain slopes
by Saturday afternoon and lingering into early Sunday morning. Most
areas are expected to see 3 to 4 hours of rain with the initial
front... then turn showery as the front moves east. There will also
be a slight chance of thunderstorms over San Luis Obispo and Santa
Barbara counties Friday night as colder air moves in aloft. Any
thunderstorms would have the potential to bring brief heavy rain and
small hail.

Rainfall amounts from Friday afternoon through Saturday are
generally expected to range between one quarter to one half inch
along the central coast... with local amounts up to one inch across
northwestern San Luis Obispo County. Otherwise... rainfall of one
tenth to one third of an inch can be expected for most areas... with
local amounts up to one half of an inch on south facing slopes and
near thunderstorms.

Snow levels will start out above 7500 feet through Friday evening
then fall to near 6500 to 7000 feet by late Friday night... and to
near 6000 feet by Saturday morning. Most of the steady precipitation
should be over before the snow levels lower significantly... so any
snow accumulation above 6500 feet is expected to be less than an
inch.

Southwest winds gusting to 35 to 45 mph are also expected over the
mountains of Ventura and Los Angeles counties and in the Antelope
Valley Friday afternoon and Friday night in advance of the front.
Winds will turn northwest over the area by Saturday morning with
gusts over 50 mph possible in the mountains... and over 40 mph in the
Antelope Valley.

The rain will impact travel across the region. Since this will be
the first widespread rain event in quite some time... roads will be
extra slick due to months of oil buildup on paved surfaces.
Motorists are urged to use extra caution in the rain. In
addition... people planning to travel into the mountains should be
prepared for winter weather driving conditions over the higher
elevations.
