| Area Forecast Discussion National Weather Service Los Angeles/Oxnard CA 156pm PDT Tuesday Jun 16 2026 Synopsis 16/155 PM. A trough building into the region for the second half of this week through this weekend will continue the night through morning low clouds and fog, even pushing them further inland, and will lead to a sharp cooling of temperatures away from the coast. Temperatures are expected to warm up again next week with increasing odds of impactful heat toward the second half of next week. Short Term - Today through Friday 16/1232 PM. Very similar conditions this afternoon to yesterday with moderate onshore flow both to the north and east. Srn CA is under a weak ridge that is nosing in from the west with H5 hgts near 590 dam. Max temps will come in within a degree or two of ydy's readings. The csts will mostly be in the 70s and the vlys in the 80s (the western San Fernando Vly will soar into the 90s again). Most areas, save for the beaches, will have above normal temps. Slight cooling is on track for Wednesday. The ridge will weaken and hgts will fall a few dam. Onshore flow will increase and the marine layer will deepen some. More of the vlys will wake up to low clouds. All of this will translate to about 3 to 6 degrees of cooling across the board. A switch to cyclonic flow aloft along with a substantial increase in onshore flow will bring a deep marine layer that will cover almost all csts/vlys with marine stratus. Strong onshore flow (~9mb) to the east will bring slow clearing to all areas with no clearing likely for some beach and nearshore areas. The deepening marine layer may support spotty offshore and some coastal drizzle in the mornings Thursday and Friday. The strong onshore push to the east will bring near advisory level winds to the western Antelope Vly in the afternoons, likely peaking on Friday as the trough axis pushes inland. The deep marine layer and strong onshore push will drop temperatures away from the csts by 5 to 10 degrees (csts will only cool 1 to 3 degrees). This cooling will bring upper 60s to mid 70s to the csts and upper 70s and lower 80s to the vlys. These vly temps are 4 to 8 degrees below normal. Long Term - Saturday through Tuesday 16/143 PM. The end of this week through at least Saturday is set to be peak June Gloom. Broad trough.ing will persist over the state through the weekend and will provide the gentle lift needed for a deep marine layer. At the surface there will be stg onshore flow to start the weekend, esp to the east. Low clouds and fog should cover the csts and all vlys and will likely xtnd into the mtn passes. The low clouds will be slow to clear and early to return. Some, perhaps many, coastal locations will see little if any clearing. Max temps will only be in the mid and upper 60s across nearshore locations with only 70s across the rest of the csts/vlys. Most max temps will end up 5 to 10 degrees below normal. The trough will then diminish heading into Monday and the onshore flow will subside somewhat. This will lead to a lessening of the amount of morning low clouds, esp in areas like the Santa Clarita Vly, and an earlier and more complete afternoon burn off. Look for 1 to 2 degrees of warming on Sunday and 2 to 3 degrees on Monday. Looking further ahead into the middle of next week there are good indications of a strong upper high building into the area which would lead to well above normal temps for the vlys and inland areas (continued onshore flow will moderate the heat for the csts). There are already low probabilities (10-30%) for major heat risk for the warmer inland valleys beginning Wednesday next week. The heat next week, if it comes to fruition, may pose significant impacts to residents and especially for out of towners. Marine 16/148 PM. Moderate to high confidence in current forecast. Conditions are generally expected to remain below Small Craft Advisory (SCA) levels across most of coastal waters through the forecast period. Winds approach SCA (Small Craft Advisory) levels with gusts 20 to 25 knots through this evening across the eastern Santa Barbara Channel. Local gusts could reach 21 kts during the afternoon and evening timeframe across the western Santa Barbara Channel, Santa Monica Basin, and nearshore Los Angeles Harbor into the San Pedro Channel NOAA Los Angeles/Oxnard CA Office: Watches - Warnings - Advisories CA...Beach Hazards Statement in effect through late Wednesday night for zones 349-350-354-362-366.
