| Area Forecast Discussion ...UPDATED National Weather Service Los Angeles/Oxnard CA 1049am PDT Tuesday Oct 7 2025 Synopsis 07/900 AM. Night through morning low clouds and fog will continue through the week with temperatures near to slightly below normal. There is a slight chance of rain for late Thursday into Friday across Los Angeles County. Short Term - Today through Thursday 07/907 AM. ***UPDATE*** Marine layer firmly entrenched across the coast and valleys with a depth ranging from around 2000 feet in LA County and sloping down to around 1500 feet along the Central Coast. Overall, expecting today to be very similar to Monday, perhaps a degree or two warmer as there is a little offshore component this morning that has some support aloft to the tune of 15-20kt at 850mb. Otherwise, a very quiet day of weather locally and not expecting much change tomorrow. ***From Previous Discussion*** Look for a fairly similar marine layer pattern on Wednesday with just a little less vly coverage. The big news is the pattern shift with strong SW flow setting up over Srn CA in response to the southward progression of a anomalously large upper low west of the WA coast. At the same time Hurricane Priscilla will begin her northward trek just off the Baja coast. This pattern shift will not affect the days weather much which will feature mostly sunny skies save for the morning marine layer stratus and cooler temps due lowering hgts and stronger onshore. It looks like Priscilla will not be near enough to the area on Thursday to affect the weather. The weather then will be dominated by the SW flow around the south end of the upper low. Offshore flow is forecast to develop from the north and this will limit the amount of low clouds south of Pt Conceptions. Max temps will continue to run 2 to 4 degrees below normal. Long Term - Friday through Monday 07/1228 AM. There is, perhaps, a little less uncertainty with the Fri/Sat forecast as more ensembles are now favoring a scenario where the strong SW flow assoc with the large upper low picks up and sweeps the moisture from Priscilla to the east. There are still some ensemble members that show rain for LA county so a 15 to 20 percent chance of rain remains in the forecast. The trough should start to disrupt the marine layer and there will be less and less morning low clouds. Weaker onshore (or even weak offshore) sfc pressure gradients will being warming to most areas Friday. Cool air advection from the trough passing overhead Saturday will cool the csts/vlys 2 to 4 degrees and the interior 4 to 8 degrees. Long wave trough.ing sets up over the area on Sunday. There should be no morning low clouds as the cool air and mixing from Saturday's trough passage will likely destroy the marine inversion. IN addition there will be some offshore flow with some gusty northerly winds. Mostly sunny skies, the lack of cool air advection and the offshore flow will allow for several degrees of warming. Even with the warming most max temps will end up 3 to 5 degrees below normal. Another trough will rotate out of the interior on Monday with another shot of cold air advection. There is the potential for some very gusty northerly winds in the wake of this trough later in the day. Cool air from the trough passage will lower max temps another 2 to 3 degrees. With almost all cst/vly locations expected to see max temps in the 70s. Marine 07/826 AM. Across the outer waters and nearshore along the Central Coast conditions are likely to remain below Small Craft Advisory (SCA) criteria through Thursday, with increasing winds to near or above SCA (Small Craft Advisory) levels possible by Friday, generally south of Point Conception. SCA (Small Craft Advisory) winds are likely for the weekend, with a 30% chance for gale force winds Saturday. For the inner waters south of Point Conception, conditions should generally remain below SCA (Small Craft Advisory) criteria through mid week. Isolated gusts approaching SCA (Small Craft Advisory) levels are possible this evening and Wednesday evening near Point Dume and the San Pedro Channel. There will then be a 30-40% chance for SCA (Small Craft Advisory) level winds Friday, with the highest chance in the Santa Barbara Channel. Similar chances on Saturday.
