FXUS66 KLOX 080231 AFDLOX Area Forecast Discussion National Weather Service Los Angeles/Oxnard CA 731 PM PDT Tue Apr 7 2026 .SYNOPSIS...07/158 PM. Warmer temperatures will return briefly Wednesday before a sustained cooling trend takes us into the weekend, along with a chance of rain. && .SHORT TERM (TUE-FRI)...07/157 PM. Relatively quiet weather is anticipated through Thursday with a modest bump up in Temperatures into Wednesday thanks to a pop up ridge and weak offshore flow from the north. There is a 30-50 percent chance of advisory level northerly winds this evening through Thursday morning focused across interior mountains from the I-5 corridor west to the Santa Barbara Mountains including the Santa Ynez Range to southwest Santa Barbara where a Wind Advisory is in effect 4 pm to midnight tonight. The transition towards offshore flow from the north and modest ridge building aloft will limit night to morning low clouds into Wednesday and Thursday mornings, however where they occur such as southern LA County, patchy dense fog will be possible. An unusually strong storm for April, a bit more typical of winter, will likely push into the region Friday from northwest to southeast across the region. Showers and scattered (20-30 percent chance) thunderstorms are likely for San Luis and Santa Barbara counties to western Ventura County through Friday afternoon, becoming widespread across the region into Friday night. Isolated minor flooding is possible with heavier showers or thunderstorms, especially where training of storms (prolonged periods of rain) occurs. Additional storm hazards may include strong winds, small hail, and cloud-to-ground lightning due to moderate instability and winds aloft. Advisory level winds are likely Friday afternoon through Saturday evening focused across interior mountains and valleys. Some cooling is expected into Friday with highs generally 70-75 and even those will likely occur early in the day, especially towards the Central Coast. .LONG TERM (SAT-TUE)...07/157 PM. Showers and thunderstorms will continue through Saturday morning or afternoon, at least for Los Angeles and Ventura counties with similar risks highlighted in the short term. Rainfall amounts of 0.5 to 1.5 inches will be common through Saturday night, highest across the mountains of Los Angeles and Ventura mountains and where thunderstorms occur. Peak rainfall rates of 0.25 to 0.75 inches seem likely given the convective nature of this cold April storm. Several inches of snow is possible mainly above 7000 feet, but locally lower. Daytime highs in the 60s will be common at low elevations Saturday and into Sunday. Broad westerly flow aloft sets up in the storms wake with isolated to scattered showers continuing through at least Monday. There is a 60-80 percent chance of a second uptick in shower activity Sunday into Sunday night as a second disturbance passes to the north with around a 10 percent chance of thunderstorms focused from Ventura County and especially to the north. Drier west to northwest flow sets up atop the region early next week with rebounding temperatures into the 70s to near 80. Above normal temperatures are favored into Mid April with odds slightly favoring above normal precipitation. So we might not be done with rain just yet. && .AVIATION...08/0227Z. At 2328Z at KLAX, the marine layer was 1000 ft deep. The top of the inversion was at 3500 ft with a temperature of 19 C. High confidence in VFR TAFs, except for KOXR, KSMO, KLAX, & KLGB. Some uncertainty vis and cigs, which may be shorter lived than forecast. Vis could be as low as 1SM at times. KLAX...Moderate confidence in TAF due to uncertainty in arrival time of cigs, and how far vis will fall. There is a 30% chance CIGs do not arrive. No significant east wind component expected. KBUR...High confidence in VFR TAF. && .MARINE...07/203 PM. Current Small Craft Advisories (SCA) look on track. SCA winds will continue across all Outer Waters through Wednesday.

The Inner Waters will reach SCA levels at times mainly during the afternoon and evening hours - through Wednesday along the Central Coast and through Thursday south of Point Conception. Localized GALE force gusts may occur near the Channel Islands Wednesday evening.
