248 FXUS66 KLOX 290548 AFDLOX Area Forecast Discussion National Weather Service Los Angeles/Oxnard CA 1048 PM PDT Sun Jun 28 2026 ***UPDATED AVIATION AND MARINE SECTIONS*** .SYNOPSIS...28/745 PM. Night through morning low clouds will prevail through most of this week, with temperatures well below normal through at least Thursday. Modest warming is likely to follow. Drizzle will be possible each night, especially near the foothills. Gusty winds will continue over the interior mountains and deserts, as well as southwest Santa Barbara County through at least early next week. && .SHORT TERM (SUN-WED)...28/810 PM. ***UPDATE*** The short term forecast issues continue to be gusty winds, cooler than normal temperatures, and extensive night to morning low clouds cover. A Wind Advisory is now in effect for the Antelope Valley (SW winds) and western Foothills, and for SW Santa Barbara County (NW winds) where gusts up to 45 mph are likely. While confidence in this forecast is moderate due to weaker gradients, winds are increasing in the areas under the Advisory this evening and believe they will not have too much trouble reaching criteria within the next few hours. Onshore gradients between LAX to Daggett are forecast by the NAM12 to increase the next few days, so the gusty winds near or above Advisory levels are likely to continue into at least mid-week. Heights aloft will lower through Tuesday, with below normal temperatures expected to persist through Thursday. High temperatures tomorrow are expected to be in the 70s and 80s, except for some 60s near the coasts. Interior temperatures will be 10 to 15 degrees below normal during this time. The extensive low clouds will continue to move inland each night, at times reaching the interior valleys and with periods of drizzle possible. The best chances of drizzle will be across the foothills of the San Gabriels, but any lower mountain or foothill locations could see occasional light drizzle. ***From Previous Discussion*** The upper trough situated over the Great Basin is expected to lift northeast into Monday. In tandem, a shortwave trough will dive due south along the British Columbia coast deepening some into Socal. The upper pattern will slow down with weak troughing continuing across the west into Thursday. Evening NW winds across SW SB county will continue Monday into Tuesday (Sub-advisory). Better chance for advisory Wed & Thurs, but marginal if it materializes. Gusty winds will continue across the far interior thru the period. .LONG TERM (THU-SUN)...28/209 PM. Good consensus among ensemble and deterministic guidance of high pressure building over the region Friday and Saturday. This will result in a warming trend into July 4th weekend as 500mb heights continue to rise and gradients trend offshore. Temperatures will likely warm even more into next week - however, there is quite the range in solutions. Stay tuned for updates. && .AVIATION...29/0545Z. At 05Z at KLAX, the marine layer was 3800 ft deep. The top of the weak inversion was 5500 ft with a temperature of 14 Celsius. High confidence in VFR TAFs for KPMD KWJF. 20% chance of MVFR ceilings at KPRB 10-16Z. Moderate confidence in ceilings at all other airports. Moderate confidence in timing (+/- 3 hours) and flight categories (+/- 1 category. KLAX...High confidence in ceilings forming tonight. Moderate confidence in timing (+/- 3 hours) and flight categories (+/- 1 category). High confidence in any easterly wind staying under 6 knots. KBUR...High confidence in ceilings forming. Moderate confidence in timing (+/- 3 hours) and flight categories (+/- 1 category). && .MARINE...28/1013 PM. High confidence in Small Craft Advisory (SCA) level winds continuing for the outer waters from the Central Coast through San Nicolas Island through this morning (lingering longer for the far northern waters), with some improvement still expected after. Chances for SCA winds will decrease today and Tuesday for the nearshore Central Coast waters. There is around a 40% chance of SCA winds over the western Santa Barbara Channel this afternoon and evening and again Tuesday. The rest of the waters will likely stay under SCA. All waters will see short-period choppy seas into early next week. && .LOX WATCHES/WARNINGS/ADVISORIES... CA...Wind Advisory in effect until 3 AM PDT Monday for zones 349-351-381-383.
