.areas of patchy fog, locally dense, across the coastal waters overnight and Saturday morning... There will be areas of patchy fog, locally dense with visibility one nautical mile or less, across the coastal waters overnight and Saturday morning. The dense fog is most likely to develop across the outer waters, off of the central coast, and off of los angeles county. Mariners should be prepared for abrupt visibility changes down to one nautical mile or less. Reduce speeds and be on the lookout for exposed rocks and other vessels, including large ships in the shipping lanes. Use radar or gps navigation if available, and consider remaining in harbor if such equipment is unavailable.

SYNOPSIS. 04/218 PM.
High pressure will bring dry and warmer conditions through Friday. There is a slight chance of light rain over northern areas on Saturday, otherwise it will be dry through the weekend with cooler temperatures. A couple of stronger and colder storms are possible between late Monday and Wednesday night with the potential for significant rain and mountain snow.
SHORT TERM (TDY-SUN). 04/216 PM.
Sunny skies covered the forecast area early this afternoon with little change expected thru sunset. Breezy to locally gusty S-NW winds will cover much of the forecast area thru the afternoon. With the abundant sunshine today, temps will warm about 6-12 degrees compared to yesterday but still be only near normal to slightly above normal overall. Highs are expected to be in the 60s to low 70s for much of the coast and vlys.
Upper level ridging with H5 heights up to 573-575 dm this afternoon will persist tonight then slowly weaken on Fri in response to an approaching E Pac upper level trof. H5 heights Fri afternoon should lower to around 571-573 dm. The upper level trof is forecast to move quickly E and reach the central CA coast by late Fri evening, then push inland late Fri night. Generally flat upper level ridging can be expected across the region on Sat with a broad westerly flow aloft. A large upper level trof over the E Pac will approach the W coast on Sun, bringing a broad SW flow aloft and H5 heights over the fcst area lowering to 566-570 dm.
Low clouds are expected to affect the Central Coast, Santa Ynez Vly and Salinas Valley tonight into Fri morning, otherwise mostly clear skies should prevail across the region tonight thru Fri. There should also be offshore pressure gradient trends tonight into Fri morning. These trends and plenty of sunshine on Fri will help to boost temps another 2-8 deg for many areas, and highs should reach the 70s for many inland coast and vly areas.
A surface cold front associated with the first E Pac upper level trof will approach the Central Coast Fri evening with increasing clouds, then the front will move thru the region while dissipating late Fri night into early Sat. There should be some light rain with the front mainly over SLO County but may briefly extend into nrn SBA County. This will be a weak and rapidly moving system so any rain should be quite light and generally less than 0.10 inch. Further S over VTU/SBA Counties, it looks like marine layer clouds should expand along the coast and into some of the adjacent vlys Fri night into Sat morning. Skies are expected to become sunny to partly cloudy Sat afternoon. Temps will turn 6-12 deg cooler for many areas on Sat, with highs in the warmest vlys and inland coastal areas in the 60s.
Some low clouds are forecast to develop along the L.A. County coast and into some adjacent vlys later Sat night into Sun morning. Otherwise, it should be mostly clear Sat night with increasing mainly hi level clouds on Sun for mostly cloudy skies. Hi temps will remain on the cool side Sun with most inland coastal areas and vlys reaching into the 60s.
Gusty sub-Advisory N winds should affect the SBA County S coast and mtns Fri evening, with Advisory-level N winds possible Sat evening. Otherwise, increasing NW-N winds should move into SLO/SBA Counties by Sat afternoon, with breezy to gusty SW-W winds over portions of VTU/L.A. Counties.
LONG TERM (MON-THU). 04/212 PM.
The 12Z deterministic EC and GFS are in fairly good agreement for the extended period, with a cool and unsettled weather pattern in the offing. The mean ensembles largely agree with this scenario as well. The large upper level trof over the E Pac will draw closer to the W coast Mon with a surface cold front approaching the Central Coast along with a slight chance of rain for that region. This front should move inland later Mon night and Tue with an increasing chance of rain and mountain snow across the forecast area. The upper level trof is forecast to move into CA Tue night and Wed with a secondary front expected to bring additional chances of rain and mtn snow to the region. The upper level trof is forecast to remain over srn CA Wed night then move very slowly E of the region on Thu. At this time it looks like there many be some residual moisture with a slight chance of showers into Thu.
It is still too early to pin down pcpn amounts for the extended period, but there is the potential for significant amounts of rain along with mtn snow down to perhaps as low as 3000 feet. Potential impacts from next week's weather system include slick roads with minor street flooding, and wintry driving conditions in the mtns with poor visibilities and snow covered roads, including in and around Interstate 5 over the Grapevine.
Needless to say, temperatures will turn well below normal by Tue and should be at least 6-12 deg below normal in all areas for Wed. Hi temps on Wed, the coolest day next week, should only be in the mid 50s to low 60s for most of the coast and vlys.
AVIATION. 04/1819Z.
At 1417Z at KLAX, There was an inversion at 900 feet at 10 degrees C, but no marine layer.
High confidence in 18Z TAFs through 06Z with VFR conditions expected throughout the area. Moderate confidence for coastal TAF sites following 06Z with the best chance of reduced vis and cigs for KSMX.
KLAX . Fairly good confidence in TAF. Good confidence that there will be no east wind component greater than 8 kt.
KBUR . Good confidence in VFR TAF.
MARINE. 04/1248 PM.
Outer Waters . Good confidence in forecast through tonight with no Small Craft Advisory (SCA) (winds or seas). High confidence in current SCA for high seas Friday, and areas of SCA level winds Friday night, especially near the Channel Islands. Good confidence in widespread winds above SCA levels Saturday, with a 10-20% chance of GALE FORCE winds Saturday night. Winds exceeding SCA levels should last into Sunday. Lower confidence in the forecast for next week. Seas and winds should come down Monday before another storm brings large swell and winds early next week.
Inner Waters N of Point Sal . Good confidence in winds and seas forecast through Friday. Moderate confidence that SCA hazardous level seas will begin Friday night and high confidence of SCA winds and sea conditions Saturday into Sunday. Lower confidence Monday into next week with another storm around Monday night into Tuesday.
Inner Waters S of Point Conception . Good confidence in sub SCA level conditions Today and Friday. There is a 30% chance of SCA winds starting Friday night near the Channel Islands and west of Santa Catalina Island. High confidence in SCA conditions developing Saturday esp in the western half of the inner waters. Lower confidence in a return to below SCA conditions Sunday. There is a chance for more SCA conditions next week.
LOX WATCHES/WARNINGS/ADVISORIES. CA . High Surf Advisory in effect from 10 PM this evening to 4 AM PST Sunday for zones 34-35. (See LAXCFWLOX). PZ . Small Craft Advisory in effect from 9 AM Friday to 6 AM PST Monday for zones 670-673. (See LAXMWWLOX). Small Craft Advisory in effect from 3 PM Friday to 6 AM PST Monday for zone 676. (See LAXMWWLOX).
.HAZARD POTENTIAL OUTLOOK (SUN-THU).
High surf and dangerous rip currents are likely through the middle of next week. Gusty west to northwest winds will create driving and boating hazards at times through next Wednesday. A couple of storms could bring winter hazards to the mountains Tuesday and Wednesday.
