FXUS66 KLOX 081006 AFDLOX Area Forecast Discussion National Weather Service Los Angeles/Oxnard CA 306 AM PDT Wed Apr 8 2026 .SYNOPSIS...08/227 AM. It will be a little warmer today. Cooler conditions arrive Thursday followed by a chance of rain and thunderstorms Friday and over the weekend. && .SHORT TERM (TDY-FRI)...08/1226 AM. A small eddy will bring low clouds and fog to the LA cst and portions of the San Gabriel Vly today. Northerly flow will bring gusty winds to the mtns this morning. By the afternoon increasing onshore flow to the east will bring gusty winds to the I-5 corridor and the western Antelope Vly. The gusts will be near advisory levels but will likely come in just under the thresholds. At the upper levels a ridge will cover the state and 576 dam hgts will be over Srn Ca. These hgts and the northerly offshore flow will team up to bring 2 to 4 degrees of warming to most areas. Onshore flow and an eddy will bring low clouds and fog to the csts and many of the vlys including the Paso Robles area Thursday morning. Increasing onshore flow in the afternoon will produce slower than normal clearing. The ridge will push to the east as cool upper low approaches the northern third of the state. The deeper marine layer and stronger onshore flow will cool max temps by 3 to 5 degrees. Despite this cooling most areas will end up 3 to 6 locally 8 degrees warmer than normal. The 555 dam upper low will not make much progress on Friday and will remain to the west of Humboldt County. Still Srn CA will be under its cool moist cyclonic flow and the clouds and chance of rain will increase through the day from the NW to the SE. The best chc of rain will occur north of Point Conception where rain and a slight chc of TSTMs will occur in the afternoon. LA county may well have to wait until the evening before seeing some rain. Since the storm is so far away the amount of rainfall that will likely fall during the day will only be around a tenth of an inch north of Pt Conception (Higher amounts, as usual, over the far NW tip of SLO county) and a trace to less than a tenth south of Pt Conception. Max temps will plummet 2 to 4 locally 4 to 8 degrees due to the combination of onshore flow, clouds, falling hgts and strong onshore flow. Most max temps will end up 2 to 3 degrees blo normal. A decent lobe of PVA moves through the area Friday evening and overnight. Rain will be likely across the entire area and there will be a slight chc of TSTMs as well. Most areas will see between a quarter and a third of an inch of rain. But there could be localized areas of higher rainfall amounts in places that experience TSTMs. .LONG TERM (SAT-TUE)...08/227 AM. The weekend will be cloudy, cool and showery. Friday night's trof will exit the area Saturday morning. Hot on its heels, however, will be an even colder (534 dam) upper low that will sweep into the area and transverse the state by late Sunday. This cold, dynamic and unstable system will bring showers and a chc of TSTMs to the area. On average this system will produce about a half inch of rain over the 2 day period. Rainfall amounts, however, will likely not be too homogeneous due to the convective nature of the system. Some area may only see a quarter inch of rain, while others could see an inch or more. Most rainfall rates will be between 0.25 to 0.75 in/hr but higher rates will be possible under any TSTM that develops. Snow levels will fall to about 6000 ft and several inches of snow is possible above that elevation. Max temps both days will only be in the 60s or 4 to 8 locally 10 degrees blo normal. There is some chc of lingering showers Sunday night, but by Monday dry NW flow will set up over the area. Both Monday and Tuesday will have mostly clear skies with rebounding temperatures (2 to 4 degrees Mon and 3 to 6 degrees Tuesday). && .AVIATION...08/0928Z. At 0822Z at KLAX, the marine layer was 900 ft deep. The top of the inversion was at 2300 ft with a temperature of 20 C. High confidence in VFR TAFs, except for KOXR (30 percent chc of IFR cigs 13Z-17Z) and KSMO, KLAX, & KLGB (20 percent chc of no low clouds, timing could be off +/- 1 hour cig hgt by +/- 200 ft) KLAX...Moderate confidence in TAF. There is a 20 percent chc that there will be no cigs. If cigs do arrive they could arrive as late as 13Z and as low as BKN003. No significant east wind component expected. KBUR...High confidence in VFR TAF. && .MARINE...07/1130 PM. Current Small Craft Advisories (SCA) look on track. SCA winds will continue across all Outer Waters through the evening and overnight hours. Local Gale force gusts (35 kts) are likely this evening through the overnight hours south of Point Conception. Gale force winds are possible south of Point Conception, especially near the Channel Islands this afternoon and evening. GALE Watches are in effect from this afternoon to early morning Thursday for the waters near the Channel Islands down south to San Nicolas Island (PZZ676) and for the Santa Barbara Channel (PZZ650).
