959 FXUS66 KLOX 020342 AFDLOX Area Forecast Discussion National Weather Service Los Angeles/Oxnard CA 842 PM PDT Tue Jul 1 2025 .SYNOPSIS...30/1100 PM. Skies will be clear except for night through morning low clouds across the coasts and some valleys through next weekend. Afternoon high temperatures will be 3 to 6 degrees below normal through the weekend. && .SHORT TERM (TUE-FRI)...01/838 PM. ***UPDATE*** Quiet weather continues over the region today, with marine layer clouds affecting the coasts and coastal valleys. Temperatures were a little warmer than expected over the interior, so highs were warmed a few degrees for Wednesday as marine layer clouds should be similar in coverage tonight into Wednesday morning. Breezy onshore winds (generally 20 to 35 mph)developed over the Antelope Valley, the I-5 Corridor, and interior San Luis Obispo County. Expecting these winds to reoccur each afternoon, along with some overnight breezy northerly winds affecting interior mountains. Will need to look into adding fog to the forecast, especially for Thursday but otherwise the forecast looks on track. STDAFDLOX ***From Previous Discussion*** Small day-to-day changes in temperatures and night to morning low clouds through at least Friday 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. A few fair weather cumulus clouds this afternoon for interior mountains with no showers expected. Interior areas will continue to be dry and breezy with elevated fire weather through at least Friday with weak Sundowner winds likely returning to southwest Santa Barbara County by Friday. .LONG TERM (SAT-TUE)...01/148 PM. A slight warming trend is likely this upcoming weekend with temperatures returning to near normal and night to morning low clouds gradually retreating closer to the coast. Above normal confidence in a significant warm up by early next week with moderate to high heat impacts possible from the coastal valleys to interior by Tuesday and possibly extending through mid week with triple digit heat possible for warmer coastal valleys to the interior. Monsoon moisture may push into Los Angeles and Ventura Counties in particular by the middle of next week and could increase heat concerns closer to the coast as well as monsoon moisture tends to disrupt the cooling effects of the marine layer. There is a small (10 percent chance) of thunderstorms focused across the mountains and deserts of Los Angeles and Ventura Counties beginning Tuesday. Dry lightning fire starts, gusty winds, and local flooding are potential monsoonal thunderstorm hazards. && .AVIATION...01/2354Z. At 2324Z at KLAX, the marine layer was 1100 ft deep. The top of the inversion was at 3600 feet with a temperature of 24 C. High confidence in VFR TAFs for KPRB, KWJF, and KPMD. Low confidence in TAFs for KBUR and KVNY with 30% percent chc of LIFR to IFR cigs 08Z-17Z. Moderate confidence in remaining airfields through 02Z. Timing of CIG/VSBY restrictions may be off +/- 2 hours and flight cats may be off by one cat during presence of low clouds. KLAX...Moderate confidence in TAF. Low clouds this evening could arrive anytime between 01Z and 05Z and cigs could be as low as 005. No significant east wind component is expected. KBUR...Low confidence in TAF with 30% chc of BKN002-008 conds 08Z-17Z Wed. && .MARINE...01/751 PM. Small Craft Advisory (SCA) winds are likely across the Outer Waters much of the time through the 4th of July Weekend. Winds are marginally at SCA levels currently and there will be a long enough lull overnight into Wednesday afternoon to end the SCA tonight and start a new one tomorrow afternoon. 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 (30-40% chance). For the nearshore waters along the Central Coast, winds and seas will likely remain below SCA levels through Thursday afternoon, then SCA level winds are likely each afternoon and evening through the weekend, especially during the afternoon and evening hours. 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. A shallow marine layer depth in place will continue to create patchy dense fog that will affect the coastal waters, especially north of Point Conception through this morning. && .BEACHES...01/1245 PM. A longer period southerly swell with marginally high heights has a moderate chance of producing strong rip currents Thursday through the upcoming holiday weekend. A beach hazards statement may be issued to highlight elevated surf conditions and strong rip current activity in the surf zone, with most powerful current expected for Independence Day and Saturday. If planning on heading to the beach over the holiday weekend, please check with a lifeguard before entering the water. Always swim near an occupied lifeguard tower. && .LOX WATCHES/WARNINGS/ADVISORIES... CA...NONE. PZ...Small Craft Advisory in effect from 3 PM Wednesday to 3 AM PDT Thursday for zones 650-670-673-676.
