FXUS66 KLOX 022026 AFDLOX Area Forecast Discussion National Weather Service Los Angeles/Oxnard CA 126 PM PDT Wed Jul 2 2025 .SYNOPSIS...02/121 PM. Near normal weather conditions are anticipated through this weekend with continued night to morning low clouds and fog near the coast. The first significant widespread heatwave of the summer is possible next week. && .SHORT TERM (TDY-SAT)...02/121 PM. Small day-to-day changes in temperatures with night to morning low clouds through at least Saturday for the coasts extending into some coastal valleys. Daytime highs will generally be in the 70s near the coast, 80s coastal valleys and 90s lower mountains to the interior. Interior areas will continue to be dry and breezy with elevated fire weather with weak to moderate (low end advisory level) Sundowner winds likely returning to southwest Santa Barbara County beginning Friday. .LONG TERM (SUN-WED)...02/121 PM. A slight warming trend is likely Sunday into Monday with temperatures returning to or just above normal with night to morning low clouds gradually retreating closer to the coast. Continued above normal confidence in a significant warm up by early next week as all guidance has some flavor of a strong ridge building into the region from the east. Moderate to high heat impacts are likely from the coastal valleys to interior as early as Tuesday and likely Wednesday into Thursday with triple digit (100s) heat. Lower confidence on the extent of the heat closer to the coast. Monsoon moisture may push into the region by the middle of next week and combined with moderate offshore trends from the north could increase heat concerns closer to the coast as monsoon moisture tends to disrupt the cooling effects of the marine layer. Heatwaves combined with instability have supported large wildland fires in the past, so increased fire activity is possible during this period. There is a small (10 percent chance) of thunderstorms focused across the mountains and deserts as early as Tuesday for Los Angeles/Ventura Counties, extending across the remaining interior areas Wednesday into Thursday or Friday. Dry lightning fire starts, gusty winds, and locally heavy rain are potential monsoon thunderstorm hazards. A slow cool down is possible heading into next weekend, however continued heat impacts are likely, especially away from the coast. && .AVIATION...02/1844Z. At 18Z at KLAX, the marine layer was 1600 ft deep. The top of the inversion was around 3600 feet with a temperature of 23 C. High confidence in VFR TAFs for KWJF, KPMD, and KPRB. Moderate confidence in remaining TAFs. Minimum flight cat may be off by one and flight categories off by 2 hours. KBUR and KVNY: there is a 20-30 percent chance that VFR conds prevail. KLAX...Moderate confidence in TAF. Moderate to high confidence in any east wind component remaining below 6 kts between 07Z and 17Z. KBUR...Moderate confidence in TAF. There is a 20% chance for no low clouds tonight. && .MARINE...02/919 AM. Small Craft Advisory (SCA) winds are likely across the Outer Waters much of the time through the 4th of July Weekend, with a lull possible tonight into Thursday morning before ramping back up. SCA winds are also likely each afternoon and evening for the nearshore waters along the Central Coast from Thursday through the weekend. Local Gale Force wind gusts are possible Thursday through Sunday, with best chances around the western Channel Islands and in the northern Outer Waters Thursday afternoon and evening (30% chance). Seas will build to 8 to 10 feet at times from this afternoon through the weekend. Inside the southern California bight, there is a moderate (30-50%) chance of SCA level winds each day through the weekend during the afternoon and evening hours through the Santa Barbara Channel (strongest winds focused in the western portions), near Point Dume, and into the San Pedro Channel. Patchy dense fog may affect the coastal waters, especially north of Point Conception overnight and in the morning hours through this weekend. && .LOX WATCHES/WARNINGS/ADVISORIES...
