| Area Forecast Discussion National Weather Service Los Angeles/Oxnard CA 248am PST Tuesday Nov 3 2026 Synopsis 03/221 AM. Partly cloudy skies today will turn mostly clear by Wednesday. Otherwise it will be dry conditions with a general warming trend and periods of offshore winds through the week. Warmest and windiest conditions likely Friday-Sunday. Short Term - Today through Thursday 03/221 AM. A 560 dam upper low will pass through northern CA today and drag a mostly dry front through the Central Coast. Rain chances have been diminishing with time and now there is less than a 20 percent chc of rain there. For the rest of the area there will just be partly cloudy skies. The front will bring 2 to 3 degrees of cooling to the Central Coast while areas south of Pt Conception will see a degree or two of warming. Offshore flow will develop in the wake of today's system. Sub advisory level winds will develop through the I-5 corridor and Santa Ynez range tonight. Northerly winds will continue overnight into Wednesday morning and then will turn to the NE in the afternoon. These winds will not reach advisory levels. As is typical will November offshore flow the interior will cool by 3 to 6 degrees while the csts and vlys will see 2 to 4 degrees of warming. Still max temps will only end up in the 70s across the csts and vlys which is 1 to 3 degrees below normal. Stronger offshore flow Thursday (2 to 4 mbs) from both the N and E will bring stronger offshore winds. Low level advisory gusts are possible across portions of the Central Coast as well the area close to the VTA/LA county line. The offshore flow and rising hgts to 578 dam will bring 2 to 4 degrees of warming to all of the area. Long Term - Friday through Monday 03/220 AM. Friday and Saturday will have the strongest winds. Offshore flow at the surface will increase to 3 to 4 mb. At the same time a ridge will nose into Northern CA and bring some offshore upper level support to Srn CA. Hgts will be near 584 dam. It looks like there will be low end advisory gusts from a few miles either side of a line drawn from Santa Clarita down through Simi Valley and out through the Pt Mugu area. Skies will be clear through the period. 2 to 4 degrees of warming each day will bring max temps into the lower to mid 80s across almost all of the csts and vlys. A large high hgt upper low develops under the ridge on Sunday and then swings to the east on Monday. This in of itself will not have too much of an effect on the SoCal weather. The most important change during this time will be the substantial weakening of the offshore flow. This along with slight hgt falls will bring 3 to 5 degrees of cooling over the 2 day period with Monday's highs still well above normal in the upper 70s to lower 80s across the csts and vlys. Looking into the crystal ball the next chance of rain will be Wed/Thu the 11th or 12th. Marine 03/221 AM. High confidence in Small Craft Advisory (SCA) west winds quickly forming this afternoon over most if not all waters south of Point Conception, including the nearshore waters of the Santa Barbara Channel and Santa Monica Bay. Short period choppy seas will also form. High confidence in SCA (Small Craft Advisory) NW to N winds shifting on Wednesday to the more traditional areas from the Central Coast to San Nicolas Island and will continue through Thursday. Short period choppy seas should be expected most areas through Thursday as a result. There is a moderate risk for low-end SCA (Small Craft Advisory) level NE winds forming this weekend from Ventura through Santa Monica. NOAA Los Angeles/Oxnard CA Office: Watches - Warnings - Advisories CA...NONE. PZ...Small Craft Advisory in effect from 1pm this afternoon to 4 am PST Wednesday for zones 650-655.
