| Area Forecast Discussion National Weather Service Los Angeles/Oxnard CA 813am PST Wednesday Nov 4 2026 Synopsis 04/251 AM. Mostly clear skies, dry conditions, a general warming trend and periods of offshore winds are likely through the week. Warmest and windiest conditions likely Friday-Sunday. Short Term - Today through Friday 04/811 AM. ***UPDATE*** Latest satellite and surface observations indicate clear skies across the area except for some clouds/fog across interior sections of San Luis Obispo and Santa Barbara counties. Current sounding data indicates a very deep inversion, around 5000 feet in depth. As for winds, northerly winds, gusting 25-35 MPH, are observed across Santa Barbara county. Forecast-wise for the immediate short term, no significant issues are expected. Current interior clouds/fog will dissipate by late morning with sunny skies expected for all areas this afternoon. As for winds, current northerly winds will diminish a bit through the day, but will likely increase once again this evening. At this time, do not see any potential for widespread advisory-level winds. Overall, current forecast has good handle on the immediate short term. So, no significant updates are expected. ***From Previous Discussion*** A weak trough that brought some showers to the Central Coast last evening is now moving out of the area. A small ridge will follow in its footsteps today. That will transition to dry NW flow Thursday. A sharper ridge will then push into northern CA on Fri. This will switch the upper level flow to the NE. 1 to 2 mb of offshore flow will develop today and then increase to about 4 mb by Friday. There will be some low clouds and dense fog across the Central Coast early this morning, but aside from the that skies will be mostly clear through the short term. The csts and vlys will warm a little today as the offshore flow starts up. Cooler air moving in to the far interior will bring 4 to 8 degrees of cooling to that area. Max temps will end up 3 to 6 degrees below normal today. Thursday will be warmer as the offshore flow kicks in and hgts rise a little. Look for 4 to 6 degrees of warming across the csts and vlys and 2 or 3 degrees over the rest of the area. Friday will see another 2 to 4 degrees of warming which will bring max temps across the csts/vlys into the upper 70s and lower 80s. There will not be too much wind today and only weak offshore canyon winds on Thursday. Friday's winds will be stronger and more noticeable but should remain below advisory level. Long Term - Saturday through Tuesday 04/251 AM. Ridging and offshore flow will continue over the weekend. While There will be canyon winds each morning there is only a 30-40 percent chance that they will reach low end advisory criteria. Skies will be mostly clear through the period. Max temps should bump up another 2 to 3 degrees Saturday and then change little on Sunday. Weekend max temps will be in the lower to mid 80s for almost all of the csts/vlys or 5 to 10 degrees above normal. A high hgt dry upper low forms under the ridge and aporaches and moves over Srn CA during the Mon/Tuesday time frame. It should have little effect on the sensable weather. The more important factor will be the weakening of the offshore flow. There should be enough to keep the low clouds away, but not enough to prevent an earlier sea breeze. Max temps should cool 2 or 3 degrees each day. Despite this cooling max, max temps will remain at least 5 degrees over normal. It should then remain dry through Wednesday the 11th. After that all long range mdls, AI, Deterministic and Ensemble all show an increased chance of rain from the 12th to the 19th. Marine 04/811 AM. For the Outer Waters, high confidence in current forecast. Today through Friday, a combination of Small Craft Advisory (SCA) level winds and seas will prevail. For Saturday and Sunday, SCA (Small Craft Advisory) level seas are expected to continue with winds dropping below SCA levels. For the Inner Waters north of Point Sal, moderate to high confidence in current forecast. Today through Thursday, there is a 50-60% chance of SCA (Small Craft Advisory) level winds in the afternoon and evening hours. For Friday through Sunday, there is a 20% chance of SCA (Small Craft Advisory) level north to northeast winds, mainly in the overnight and morning hours and seas will approach SCA (Small Craft Advisory) levels. For the Inner Waters south of Point Conception, moderate to high confidence in current forecast. Today through Thursday, high confidence in winds and seas remaining below SCA (Small Craft Advisory) levels, except for SCA (Small Craft Advisory) winds in the western Santa Barbara Channel in the late afternoon and evening hours. For Friday through Saturday, there is a 20-30% chance of SCA (Small Craft Advisory) level northeast winds from Ventura south to Santa Monica in the night and morning hours. On Sunday, winds and seas are expected to remain below SCA (Small Craft Advisory) levels. Through Thursday, the gusty winds will likely result in choppy, short-period, seas.
