.SYNOPSIS...
Fair, cool and dry weather will continue through Saturday. A 
winter storm will move south along the Coast, spreading rain from 
north to south over Southern California beginning Saturday night, 
and continuing through Monday. Steadier rainfall and strong, 
southwest winds will accompany the cold front on Sunday, becoming 
more showery and colder on Monday, with snow showers over the 
mountains. Locally heavy rainfall is possible at times. The storm 
will exit to the east Monday night, but colder than normal 
conditions will continue through at least the middle of next week.
Another storm could impact the region next weekend.

.DISCUSSION...FOR EXTREME SOUTHWESTERN CALIFORNIA INCLUDING ORANGE...
SAN DIEGO...WESTERN RIVERSIDE AND SOUTHWESTERN SAN BERNARDINO
COUNTIES...

Quiet before the storm arrives, with cool and dry and tranquil 
conditions continuing through Saturday, although look for some 
increasing cloudiness by Saturday afternoon from the north. 

A major winter storm will develop Saturday over the PacNW, 
sweeping a strong Pacific front across coastal California through 
Sunday. Rain will develop over Orange and San Bernardino Counties 
Saturday evening, spreading southeast through Sunday morning. Rain
will be heavy at times on Sunday, with the potential for both low
lying and urbanized flooding, as well as flash flooding in steep 
terrain and near recent burn scars in San Bernardino and Riverside
Counties, mainly during the day Sunday. Precipitation totals have
not changed much with this latest forecast cycle; here are the 
latest expected amounts:

Storm total precipitation amounts: 

Coast and Valleys: 0.75 to 1.50" 
Mountains: 2-4" (except locally 4-6" on the coastal slopes
                 of the San Bernardino Mountains) 
Deserts: 0.25-0.50"

Rain will change to snow later in the day as snow levels tumble 
from around 7000 feet Sunday morning, to as low as 3500 feet by 
Sunday evening over San Bernardino County, with the cold air 
spreading into San Diego County by late Sunday night. Snowfall 
will be heaviest in the upslope areas of San Bernardino and 
Riverside County mountain areas, with several feet of snow 
possible above 7000 feet, and 5 to 10 inches possible in the Big 
Bear and Wrightwood areas. Impacts to the busy mountain freeways 
will be possible as well Sunday evening through Monday as those 
snow levels come crashing down. Continued snow showers on Monday 
could continue to impact the passes, through Monday evening in San
Diego County, with favored wrap around and island banding setting
up on Monday. 

Expected snowfall amounts:

Above 7500 feet: 1 to 2' 
6000-7000 feet: 4 to 10" 
5000-6000 feet: 2 to 4" 
3500-5000 feet: 1 to 2"

Wind energy will be robust with this winter storm. Winds at the 
coast could easily hit 35 mph especially with the frontal band on 
Sunday, spreading gusty winds inland of 30 to 35 mph at times. 
Winds will be stronger over the mountains and deserts with gusts 
through the passes of 60 to 70 mph possible. 

Showers will come to an end up Monday evening in San Diego 
County. Ensemble forecasts favor West Coast troughing persisting 
through the middle of next week, with very cold conditions in the 
sheltered valleys, high desert, and especially in the mountains 
with fresh snow pack possible. Low temperatures in the single 
digits will be likely in the San Bernardino Mountains. 

Cool conditions will moderate briefly later next week, before 
another storm system arrives next Friday and Saturday, with colder
conditions and the potential for another significant rain and 
mountain snow event.

.AVIATION...
092005Z...Mostly clear with unrestricted VIS through tonight. SCT 
low clouds with bases around 2500 feet are expected near the coast 
08Z-16Z Saturday. Low confidence for CIG impacts at TAF sites.

&&

.MARINE...
No hazardous marine conditions are expected through Saturday. For 
Saturday night through Monday, a storm will likely generate west-
northwest winds gusting to 25-30 kt, rough seas, and reduced 
visibility at times in moderate to heavy rain. Conditions will 
improve on Tuesday.

&&

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