&&
.DISCUSSION...FOR EXTREME SOUTHWESTERN CALIFORNIA INCLUDING ORANGE...
SAN DIEGO...WESTERN RIVERSIDE AND SOUTHWESTERN SAN BERNARDINO
COUNTIES...
From previous discussion...
The cold low currently over SoCal will slowly fill and become an
open wave as it moves inland this afternoon/evening. It will
still have enough instability and moisture to trigger scattered
showers through the afternoon, but that will diminish this
evening as the moisture decreases and the airmass stabilizes. The
potential still exists for the odd tstm, but the probability of
occurrence is very small.
The band of light rain with embedded showers persists over San
Bernardino County, western Riverside County and Orange County, but
is weakening steadily. A few light showers continue over San
Diego County, from near the coast to the Borrego Desert. In those
areas where rain is falling, it's accumulating at a rate of
approximately 0.01 to 0.10 inch per hour. Additional rainfall
could range from a few hundredths to nearly three tenths of an
inch in some locations. As the low pressure system moves
eastward, the rain and showers will continue to taper off and will
likely end by late evening.
Sunday will be dry and warmer with weak offshore flow, followed
by a period of much stronger offshore flow Monday and Tuesday as a
deep trough over Utah moves southwest into AZ and a sfc high
moves into the Great Basin. The wetting rains will mitigate the
fire weather concerns somewhat, at least at the beginning of this
Santa Ana event. But strong, dry Santa Ana winds will surface in
the mountains, foothills, inland valleys and Orange County, and
will dry the fuels fairly quickly Monday. Winds in these areas
will range from 20-40 mph with gusts in the wind prone areas of 60
mph or more. The winds remain fairly strong Tuesday with very low
humidities.
Warm and dry days with cool clear nights will continue for
Wednesday through Friday, with weaker offshore winds.

.AVIATION...
132000Z.... A few light SHRA are persisting in Riverside and Orange
counties at this hour. These showers are expected to taper off
around 21-22Z. SCT-BKN clouds with bases 2500-4000 and tops to 10000
ft will persist at coastal and valley TAF sites through this evening
with coastal mountain slopes obscured. MOD SHRA and a thunderstorm
or two could develop over the mountains through this evening,
tapering off around 01-02Z. Brief, heavy downpours will lower VIS to
1-3 SM at times, with storm bases around 4000 ft MSL and tops to
25000 ft MSL. CIGS may briefly lower to around 1500-2500 ft MSL in
heavier showers. SCT-BKN clouds with bases around 4000 ft MSL
continuing into Sunday with coastal mountain slopes remaining
obscured.
&&
.MARINE...
A few light showers and a thunderstorm or two are possible through
this afternoon. Thunderstorms may produce brief heavy rain, gusty
winds, and cloud to water lightning. A Marine Weather Statement
remains in effect through this afternoon.
&&
.BEACHES...
A long period south-southwest swell of 2-3 ft/17-19 sec from 215
degrees will build today continuing elevated surf and strong rip
currents through the weekend. A Beach Hazards Statement remains in
effect for Orange and San Diego County Beaches through Sunday
evening.
There is also a slight chance of thunderstorms at the beaches
through this afternoon.
&&
.FIRE WEATHER...
Wetting rains last night and today will alleviate the fire
weather concerns, albeit briefly, at the beginning of the Santa
Ana event which begins early Monday morning. Isolated to scattered
showers will end tonight. On Sunday the fuels begin to dry out,
but the really strong offshore winds and dry air won't arrive
until Monday. That's when critical fire weather conditions are
most likely.
Northeast to east winds of 20 to 40 mph with isolated gusts over
60 mph are expected in the foothills and wind prone areas. The
strong winds will likely reach the Orange County coast. Humidity
will fall into the single digits and teens late Monday morning,
with poor recovery Monday night. Winds will be strongest on
Monday, decreasing a little on Tuesday, but conditions will remain
critical. Tuesday night humidity recovery will be better and
winds lighter.

.SKYWARN...
Skywarn activation is not requested. However weather spotters are
encouraged to report significant weather conditions.
