Santa Ana winds will continue into Saturday, with the strongest 
winds occurring this afternoon across the mountains and coastal 
mountain slopes. A weak low pressure will allow for light rain and 
snow showers to develop across the mountains on Saturday. 
Precipitation amounts will remain very light with this activity. 
Onshore flow is expected to return on Sunday and persist through 
Tuesday before turning offshore again on Wednesday.



Evening Update: The Santa Ana winds are easing this evening in the 
northern areas and the wind advisory will be allowed to expire. 
Gusty winds will continue overnight in San Diego County, and the 
wind advisory will continue in effect in those areas through mid-
morning Saturday. No other updates were needed to the forecast this 
evening. The offshore pressure gradient will continue to relax 
through tonight as the ridge moves eastward towards the Rockies. 
Winds look to slowly weaken through this evening across northern 
areas, and overnight across San Diego County.

Short Term Discussion: An upper-level low pressure system will 
progress eastward on Saturday over our region, but it is lacking any 
substantial moisture. There is a very slight chance for flurries 
over the mountains Saturday afternoon and evening but any 
precipitation will remain light. Highs will cool by several degrees 
as winds turn back onshore, and relative humidity will increase. 
This system will quickly move east of the region on Sunday and 
warmer temperatures will redevelop.

Longwave troughing looks to develop across the West Coast later on 
Monday into Tuesday. Models begin to diverge on strength and timing 
of shortwaves moving through the region. The 12z ECMWF EPS mean is 
showing a slightly stronger ridge off of the West Coast and a 
stronger trough. However, ensemble members amongst the 12z ECMWF 
suite show a wide range of solutions in regards to timing of the 
trough moving through Southern California; a slower progression will 
lead to weaker winds. After the trough passes winds will turn back 
offshore. This uncertain timing is leading to a large spread in high 
temperature guidance. However, a ridge looks to rebuild sometime 
towards the middle of next week with a slow warming trend expected.


FIRE WEATHER...Improving RH and decreasing wind tonight through 
Saturday will help to ease local fire weather conditions, and that 
trend will continue through early next week.


290405Z...Northeast to east winds will continue through Sat morning 
across the coastal mountain slopes and into the valleys and inland 
Orange County with gusts of 25-30 kt and local gusts to 40 kt 
possible in the Santa Ana Mountains, below San Gorgonio Pass and 
along the coastal slopes of the San Diego mountains. Moderate to 
strong up/downdrafts and LLWS are expected over and west of the 
mountains through Sat morning, including vcnty KSNA, KONT and KCRQ 
at times.

Otherwise, SCT-BKN high clouds at/above 25,000 feet MSL and 
unrestricted vis tonight, with clouds lowering to 15,000 feet MSL 
Sat morning. 


Easterly winds will weaken tonight and Saturday. No hazardous marine 
conditions are expected tonight through Wednesday.


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


CA...Wind Advisory until 10 AM PST Saturday for San Diego County 
     Mountains-San Diego County Valleys.
