| Area Forecast Discussion National Weather Service Los Angeles/Oxnard CA 136pm PDT Monday August 17 2026 Synopsis 17/1213 PM. Night through morning marine layer clouds will be confined to the coastal areas through much of this week. Warmer and drier conditions are expected away from the immediate coast, with peak heat likely being Tuesday through Thursday when moderate heat risk is expected in warmest locations. Short Term - Today through Thursday 17/107 PM. Heat continues to be the main story this week as a very large upper high shifts westward from Texas to Arizona over the next few days. 500 mb heigheights will increase from around 592 dam to 594/595 dam on Tuesday. Meanwhile, the surface gradients won't change too much, with the general trends of the W/E (LAX-DAG) gradient weakly onshore during the mornings, increasing slightly during the afternoons, while the N/S (LAX-BFL) gradient near neutral or weakly offshore in the mornings becoming weakly onshore in the afternoons. Between the slight increase in 500 mb heigheights and the weak onshore flow in the morning, marine layer clouds will stay confined to the coastal locations south of Point Conception (if they even get to the beaches at all). For the Central Coast, good confidence in marine layer clouds each morning. The high pressure with higher than normal heigheights for this time of year, along with weaker than normal onshore flow, will bring another round of heat to Southern CA. Temperatures will increase each day through at least Thursday, bringing above normal temps to all areas, save for the Central Coast which will end up a few degrees within to below normal. 2 to 4 degrees of warming (locally 6 degrees across the Central Coast) will occur Tuesday and an additional 1 or 2 degrees of warming on Wednesday. Thursday, 1 to 2 degrees of warming will be possible for Ventura and Los Angeles Counties, though up to 3 degrees of cooling is possible for the Central Coast. The strong inversion, much warmer than normal sea surface temps and the warm atmosphere will also bring warmer than normal overnight low temps to much of the area. Most coast/valley locations will only have lows in the upper 60s to lower 70s. The combination of warmer than normal highs and lows will bring Moderate HeatRisk to many areas. Heat advisories go into effect Tuesday through Thursday for the San Fernando, San Gabriel, and Santa Clarita Valleys as well as the lower mtn elevations. There is a 40 percent chance the downtown LA area, the VTA county valleys, and the Santa Monica mountains will also need heat advisories starting Wednesday. Additionally, there is a small chance that heat advisories will need to be extended into Friday. Please see the product LAXNPWLOX for all of the details. Gusty north winds will affect southwest Santa Barbara County and the I-5 corridor near the Grapevine each evening and overnight. While most of these winds are expected to remain below advisory levels, there is a chance for advisory level winds in the Gaviota area this evening. Long Term - Friday through Monday 17/136 PM. There will be a little bit of cooling on Friday mostly due to an increase in mid and high level clouds. Still, max temps will remain well above normal, and like mentioned in the short term discussion, there is a small chance of heat advisories needing to be extended for portions of the area. The upper high is forecast to migrate to the four corners area by Thursday night, which will set up SE monsoon flow over Southern CA. This SE flow will allow precipitable Water values to approach 1.5" across southern L.A. County starting Friday afternoon. This influx of moisture will allow for a 5-10 percent chance of showers or thunderstorms to to develop over the LA County mountains and Antelope Valley Friday afternoon through the weekend. The upper high will be nudged a little to the east over the weekend as a weak trough moves through the PACNW and the northern half of CA. The weak lift from the trough may bring a little better low cloud development, although this is far from certain. Look for 1 to 2 degrees of cooling each day - maybe a little more for SLO county due to the proximity to the trough. The cooling will bring most areas north of Pt Conception down to near or below normal temps. South of Pt Conception, however, most max temps will remain a few degrees above normal. Marine 17/1207 PM. For the Outer Waters, high confidence in current forecast. Today through Saturday, Small Craft Advisory (SCA) level winds can be expected. Building short-period seas can be expected across the Outer Waters, rising to the 6-9 foot range. For the Inner Waters north of Point Sal, moderate confidence in current forecast. Today through Wednesday, there is a 30-40% chance of SCA (Small Craft Advisory) level winds in the afternoon and evening hours. For Thursday through Saturday, there is a 50-70% chance of SCA level winds in the afternoon and evening hours. For the Inner Waters south of Point Conception, moderate to high confidence in current forecast. For the western half of the Santa Barbara Channel, there is a 60-80% chance of SCA (Small Craft Advisory) level winds tonight through Tuesday night...then a 30-40% chance of SCA (Small Craft Advisory) level winds Wednesday through Saturday. Elsewhere south of Point Conception, high confidence in winds and seas remaining below SCA (Small Craft Advisory) levels today through Saturday. NOAA Los Angeles/Oxnard CA Office: Watches - Warnings - Advisories CA...Heat Advisory in effect from 10am Tuesday to 8pm PDT Thursday for zones 38-88-343>345-351-353-371>373-375-376-379-380-548.
