927 FXUS66 KLOX 291053 AFDLOX Area Forecast Discussion...UPDATED National Weather Service Los Angeles/Oxnard CA 353 AM PDT Sun Jun 29 2025 .SYNOPSIS...28/211 PM. Dry conditions and near-normal temperatures will persist for the remainder of this weekend and through early next week. A slight cool-down is expected for the middle of next week, though dry conditions will persist. Expect night through morning low clouds and patchy fog over the coasts and some coastal valleys. && .SHORT TERM (TDY-TUE)...29/258 AM. The streak of uneventful typically June weather will continue through the 3 day short term and beyond. Currently the marine layer is about 1000 ft deep there is no eddy so low clouds have been slow to develop and will not make much of penetration into the vly. Clearing will be a little faster and complete today as well. As a result there will be above normal temps across the LA/VTA vlys as well as some of the interior coastal sections. The onshore push will be at a minimum tonight and Monday morning. This will keep most of the vlys cloud free and will allow for another day of good clearing. The onshore push increases noticeablyin the afternoon and the stronger seabreeze will bring several degrees of cooling to the VTA and LA vlys. Many areas of LA County will see above normal temperatures, but SLO/SBA/VTA counties will likely all come in with blo normal temps (5 to 10 degrees blo normal in the case of the Central Coast). On Tuesday a high hgt (580 dam) upper low that has been spinning harmlessly to the west of the area will begin to move to the east and will turn the flow aloft more cyclonic. Moderate onshore flow to the east will combine with the lift form the upper levels to bring the low clouds back into the vlys and also delay clearing. After a two day reprieve the west coasts of SBA/VTA counties will see limited or no clearing. The increased onshore push to the east will bring gusty (but sub advisory level) winds to the western Antelope Vly. .LONG TERM (WED-SAT)...29/1223 AM. There will be very little change in the benign weather through the course of the xtnd period. The high hgt upper low will slowly transverse the state on Wed and Thu. A broad troffing pattern will set up behind it for Fri and Sat. H5 hgts will rise from 582 dam to ~586 dam from Wed to Sat. At the sfc the onshore push to the east will continue its diurnal cycle varying from about 4 mb in the morning to 8 mb in the afternoon. The onshore push to the north will follow a similar pattern (varying from about 2 mb to 5 or 6 mb) on Wed and Thu, but will weaken considerably on Fri and Sat even going weakly offshore in the mornings. The low cloud pattern will continue through the period. The clouds coverage will be greatest and the clearing the slowest (and non existent across the west facing beaches of VTA/SBA counties) on Wed and Thu with the strongest onshore push and greatest cyclonic turning aloft. Look for a reduction in the low clouds for the LA/VTA vlys as well as the SBA south coast on Fri and Sat with slightly faster/better clearing. Max temps will not exhibit much day to day variance with the exception of a slight warming trend for the csts/vlys Fri and Sat due to the lesser marine layer. Look for mostly 70s across the csts (some 60s for the Central Coast), 80s for most of the vlys and 90s across the lower elevation mtns and far interior. These Max temps are 3 to 6 locally 8 degrees blo normal for this time of year. With continued strong afternoon onshore pressure gradients, gusty southwesterly winds can be expected each afternoon/evening across interior sections. However, speeds should remain below advisory levels. && .AVIATION...29/1053Z. At 0718Z at KLAX, the marine layer was 1000 ft deep. The top of the inversion was at 1500 ft with a temperature of 25 C. High confidence in VFR TAFs with afternoon/evening gusty SW winds at airfields: KPRB, KWJF and KPMD. Timing of CIG/VSBY restrictions may be off +/- 2 hours and flight cat minimums off by one. KLAX...Moderate confidence in 12Z TAF. There is a 30% chance of LIFR CIGs 003-004 through 15Z Sunday. Timing of flight cat changes may be off +/- 2 hours. No significant wind issues expected through the forecast period. KBUR...Moderate confidence in 12Z TAF. There is a 30% chance that IFR/MVFR cigs arrive after 06Z Mon. Otherwise, VFR conditions are expected to prevail with seasonable onshore flow. && .MARINE...29/239 AM. For the Outer Waters, moderate to high confidence in current forecast. Through Tuesday, high confidence in winds and seas remaining below Small Craft Advisory levels and much quieter than usual. For Wednesday through Friday, there is a 30-50% chance of both SCA level winds and seas. For the Inner Waters north of Point Sal, moderate to high confidence in current forecast. Through Wednesday, winds and seas will remain below SCA levels and remain much quieter than usual. There is a 25% chance of SCA level seas on Thursday and Friday. For the Inner Waters south of Point Conception, high confidence in current forecast. Today through Thursday, winds and seas will remain well below SCA levels. && .LOX WATCHES/WARNINGS/ADVISORIES...
