***UPDATE***
A weak storm system is crossing the area tonight, with an upper closed low moving inland over Central California. Rain began to affect the area this morning, mainly affecting San Luis Obispo and Santa Barbara Counties (although light amounts were recorded over Ventura and LA Counties as well). For the northern counties, top rainfall amounts so far range from around a tenth of an inch to a quarter of an inch, highest over the mountains. Gusty south to west winds have been observed over the interior sections, strongest through passes and canyons of LA County into the Antelope Valley. The gusts are generally 30 to 40 mph, but with a couple of sites showing up to 45 mph. The winds will diminish some overnight but will resume again Sunday afternoon and may see more widespread gusts between 40 to 45 mph.
As for rainfall tonight, expect scattered light showers through the night with additional totals generally below 0.05 inch except for up to 0.15 inch over the mountains. Some areas may remain dry, and there is a slight chance of showers lingering along the Central Coast and mountains into Sunday morning.
Skies will begin clearing by late morning into Sunday afternoon, especially for the coast and valleys south of Point Conception. Daytime highs are expected to remain in the 60s, 6 to 12 degrees below normal. As mentioned above, breezy winds through the interior passes and canyons into the Antelope Valley Sunday afternoon may approach Advisory levels.
Looking into early next week, decreasing clouds are forecast along with a warming trend. Monday will see a few degrees of warming, with more substantial rises well into the 70s on Tuesday. Wednesday may see a few locations hit 80 degrees.
(Wed-Sat), 25/218 PM.
Still quite a bit of uncertainty mid to late next week as another weak upper level low approaches the area Wednesday. The system is partially cut off from the jet stream so timing is an issue and it's lacking in moisture. Models have been slowing the arrival of this system and it now looks like it will be at least Thursday before it arrives locally. There are some small rain chances in the forecast but will probably need another few days to get a better handle on it.
Following that, weak high pressure will return to the West coast through Saturday for warming temperatures.

For the Outer Waters, high confidence in current forecast. Through Sunday, winds and seas are expected to remain below SCA levels. Chances for SCA level winds will increase from Monday afternoon onward. Seas will increase Wednesday onward and flirt with advisory levels (10 ft) 30 NM from shore Thursday into Friday.
For the Inner Waters north of Point Sal, moderate to high confidence in current forecast. High confidence in winds and seas remaining below SCA levels through Monday morning. Chances for SCA winds will increase each day next week. Seas are likely to remain below advisory levels through this timeframe.
For the Inner Waters south of Point Conception, moderate to high confidence in current forecast. West winds just below SCA levels will continue until midnight tonight. Sunday afternoon and evening, W winds will increase back up to SCA levels across the entire Santa Barbara Channel and an advisory has been issued for that zone. For PZZ655, the northern portion of the zone will be impacted by near advisory levels, and may expand further southward into the San Pedro Pass. An advisory may be needed for that zone for Sunday afternoon and evening, but held off as current guidance suggests winds will be just below advisory levels for the larger portion of the zone. Generally moderate chances for SCA winds each afternoon and evening across the western half of the SB Channel next week.
A weak system will bring spotty showers across the coastal waters into tonight with a slight chance of showers lingering into Sunday (especially morning hours).
Ca, NONE. PZ, Small Craft Advisory in effect from 3 PM to 9 PM PDT Sunday for zone 650. (See LAXMWWLOX).
