SYNOPSIS
24/233 AM.

Strong onshore flow and a deep marine layer will maintain much cooler than normal temperatures across much of Southwest California through at least Friday. Areas of night through morning low clouds with patchy fog and drizzle are expected across the coast, valleys, and foothills, with only partial afternoon clearing. Warmer weather is expected by the weekend into early next week.

.SHORT TERM (TDY-FRI)...24/311 AM.

The next three days will be all about how the marine layer low cloud pattern develops and dissipates each night and morning.
Synoptically a broad upper trof will move over the area today followed by fast NW flow Thursday and then a fast moving inside slider on Friday. The onshore flow will weaken each day with diurnal afternoon maxes to the east about 8 mb today, 7 tomorrow and 6 on Friday. The corresponding push to the north will be 2, then 1 with Friday's gradient switching to about a mb offshore.

The one thing to watch today is the trof that the mdls are not impressed with. Satellite shows a slightly stronger looking system that has even produced a lightning strike in the last two hours. That said it looks like the bulk of this trof's energy is going to pass to the south.

Low clouds currently cover most of the csts/vlys with a notable exception of the SBA south coast and the VTA coast. The low clouds will likely move over the VTA coast but expect the SBA south cst to remain clear. The capping inversion is very weak and this combined with the deep marine layer should result in decent coastal clearing for the coasts and partly cloudy skies due to strata cu formation in the vlys. With similar cloud condition as ydy the lower hgts from the approaching trof should bring a few degrees of cooling to most areas. Max temps today across the csts/vlys will be in the 60s or 6 to 12 degrees blo normal.

The trof moving over the area late this afternoon and evening should deepen the marine layer again there will be enough lift to produce some patchy evening drizzle. With the offshore trends esp from the north there should be decent clearing Thursday afternoon.
The csts/vlys will respond to the additional sunshine and weaker sea breeze with 1 to 3 degrees of warming but residual cool air from the trof will cool the interior 3 to 5 degrees.

On Thursday evening/Friday morning the lift from the inside slider should somewhat counter act the offshore trends in the sfc gradients and bring low clouds to much of the csts/vlys but it does look like the the VTA and South SBA csts will be clear. Some north flow will bring clouds to the north slopes near the Kern County line. The NW-N flow from the inside slider will bring near advisory level winds to the northern LA mtns and portions of the Antelope Vly. The developing offshore flow from the north should bring total clearing. The offshore flow form the north, plenty of sunshine will bring 3 to 6 degrees of warming to most areas. Max temps will still mostly be 4 to 8 degrees blo normal.

.LONG TERM (SAT-TUE)...24/319 AM.

Xtnd mdls and ensembles are all in good agreement that weather will take decidedly clearer and warmer turn for the weekend and Monday. A ridge will move into and over the state hgts will reach about 578 dam Sunday and might hit 580 dam on Monday. There will only be weak onshore flow to the east and 2 to 4 mb of offshore flow from the N. Skies should be clear through the period. Max temps will rise 2 to 4 degrees each day. Monday's Max temps will be in the 70s and lower 80s or a few degrees above normal.

The ridge is forceast to break down on Tuesday and onshore flow will increase. There might be some patchy low clouds in the morning. Max temps will cool a few degrees.

AVIATION
24/0545Z.

At 0505Z at KLAX, the marine layer was 1900 feet deep. The top of the inversion was at 5300 feet with a temperature of 11 C.

Low to moderate confidence for coastal/valley TAFs and high confidence for desert TAFs. The low clouds will reform in a fairly haphazard manor. There is a 30 percent chc that KSBA will have MVFR cigs through 17Z. Good confidence that cigs will remain in MVFR range. Low confidence in VFR transition which could be off by as much as 2 hours.

KLAX...Moderate confidence in TAF. No east wind component is expected. Low clouds may not arrive until 09Z-10Z. There is a 30 percent chc that cigs will remain under 030 through 17Z. Good confidence that there will be no east wind component.

KBUR...Low confidence in TAF. Low clouds could arrive any time between 08Z-13Z. Cigs hgts will likely fall somewhere between 015 and 020. VFR conds likely by 19Z but SCT conds may hold off until 22Z.

MARINE
23/1011 PM.

For the Outer Waters, moderate to high confidence in current forecast. Today through Wednesday afternoon, high confidence in winds and seas remaining below Small Craft Advisory (SCA) levels.
For Thursday through Sunday, high confidence in combination of SCA level winds and seas. Across the two southern outer water zones (PZZ673/676), there is a 50-60% chance of Gale force winds Thursday and Friday afternoon/night.

For the Inner Waters north of Point Sal, moderate to high confidence in current forecast. Today through Wednesday night, high confidence in winds and seas remaining below SCA levels.
For Thursday through Friday, there is a 60-80% chance of SCA level winds, especially in the afternoon and evening hours. For Saturday and Sunday, there is a 40-50% chance of SCA level winds, especially in the afternoon and evening hours.

For the Inner Waters south of Point Conception, moderate to high confidence in current forecast. Winds are increasing through the Santa Barbara Channel tonight and the current SCA looks on track.
Expecting a break in the winds Wednesday morning, with a high chance (60-80%) for SCA winds Wednesday afternoon/evening for both inner waters zones. Winds will pick back up Thursday morning for the SBA channel (with a 20-30% chance of Gale force winds on Thursday), and reaching the waters south of Point Mugu Thursday afternoon. SCA wind or seas will last much of the time Thursday through Saturday.

LOX WATCHES/WARNINGS/ADVISORIES
CA...NONE.
PZ...Small Craft Advisory in effect from 3 PM this afternoon to 3 AM PDT Thursday for zones 650-673-676. (See LAXMWWLOX).
