713 FXUS66 KLOX 111525 AFDLOX Area Forecast Discussion...UPDATED National Weather Service Los Angeles/Oxnard CA 825 AM PDT Fri Jul 11 2025 .SYNOPSIS...11/133 AM. Night through morning low clouds and patchy fog will affect the coasts and lower valleys into next week. Max temperatures will cool today and Saturday and will end up several degrees below normal. There will be continued cooling through the middle of next week with valley highs on Tuesday only in the 80s. && .SHORT TERM (TDY-SUN)...11/747 AM. ***UPDATE*** An eddy spun up overnight, allowing marine layer clouds to push into the coastal valleys south of Point Conception, including into Burbank. The marine layer has risen to about 1000 ft south of Point Conception while it remains under 500 ft north as a result of the eddy. In addition, onshore gradients will continue to strengthen into the afternoon, and clouds may remain hugging the coasts through the day. These onshore gradients will also help cool down the areas on the coastal side of the mountains (including the coastal slopes) today, while the temperatures across the far interior areas will remain in the low triple digits. Max temperatures today will range from 60s to 70s across the beaches up to 80s to mid 90s across the coastal valleys. Additionally, the strong onshore push will bring gusty winds to the interior, such as the Antelope Valley western foothills, where local gusts to 45 mph will be possible. ***From Previous Discussion*** The onshore push is stronger by 2 to 3 mb this morning compared to ydy both to the north and east. As a result there is better marine layer stratus coverage. By sunrise low clouds will cover almost all of the coasts and much of the lower vlys. The increase in marine layer and onshore flow will bring 1 to 2 degrees of cooling to the csts and 3 to 5 degrees across the vlys. This cooling will bring most cst/vly locations down to a couple degrees blo normal. The onshore push this afternoon is forecast to be near 9 mb and this is strong enough to keep a few west facing beaches cloudy all day. Saturday will be very similar to today. There will likely be a little more marine layer clouds in the vlys as an eddy should spin up. This will result it a few more degrees of cooling. Look for 70s and lower 80s for most of the csts (mid to upper 60s for the Central Coast`s beaches) and mid 80s to mid 90s for the vlys. The strong onshore flow will, again, keep a few beaches socked in with clouds. Gusty west winds across the Antelope Vly may reach low end advisory levels. Very similar weather is likely Sunday as there will be little to no change in the major weather parameters. .LONG TERM (MON-THU)...11/133 AM. Fairly dull weather on tap for the xtnd fcst. Weak ridging extending from the SW will cover the state through Wednesday. On Thursday weak cyclonic flow is forecast to move over the state. Hgts will fall slowly through the period from 594 dam Monday to 590 dam on Thursday. More importantly there will be mdt to stg onshore flow both to the north and east. The afternoon push to the east is forecast to be near 10 mb each day. Look for night through morning low clouds and fog across the coasts and into the lower vlys (the 590+ dam hgts should smoosh the marine layer low enough to prevent deep vly penetration). The strong onshore flow will likely mean slow to no clearing for many beach areas. Monday`s max temps will be near 70 at the beaches with 70s across the rest of the coastal areas. The vlys will see max temps in the 80s and lower 90s. Tuesday`s max temps will be 2 to 4 degrees cooler and end up 4 to 8 degrees blo normal for this time of year. Temps will not change much from those readings on Wed and Thu. The strong onshore flow will bring gusty likely advisory level winds some of the mtns and the western portions of the Antelope Vly and foothills. Additionally, the gusty winds across the mtns and interior along with fairly warm temperatures and fairly low humidities will bring an uptick in fire weather danger. At this time there is no monsoon threat. && .AVIATION...11/1053Z. At 08Z at KLAX, the marine layer was 800 ft deep. The top of the inversion was near 2700 feet with a max temperature of 27 C. High confidence in TAFs for KPMD, KWJF, and KPRB. Moderate confidence elsewhere. Flight category changes may be off by two hours and one flight category. There is a 20-30 percent chance of IFR or lower cigs/vsbys for KBUR and KVNY through 17Z. KLAX...Moderate confidence in TAF, except low confidence after 00Z when flight category changes may be off by 3+ hours. There is a 10 percent chance of 6 kts east wind component at times between 10-17Z. KBUR...Moderate confidence in VFR TAF. There is a 20-30 percent chance of IFR or lower cigs/vsbys between through 17Z. && .MARINE...11/824 AM. No hazardous winds or seas expected through the forecast period. Night to morning patchy dense fog is possible at times through this weekend, with highest chances along the Central Coast. && .LOX WATCHES/WARNINGS/ADVISORIES... CA...NONE. PZ...Small Craft Advisory in effect until 9 AM PDT this morning for zones 673-676.
