Area Forecast Discussion National Weather Service Los Angeles/Oxnard CA 405am PDT Sunday July 13 2025 Synopsis 13/158 AM. Night through morning low clouds and patchy fog will affect the coasts and most valleys into next week. Max temperatures will warm slightly today and Monday but remain below normal except for far interior valleys. A cooling trend will develop Tuesday and continue through the middle of next week when valley highs are only expected to be in the 80s. Short Term - Today through Tuesday ...13/158 AM. A small upper high over Srn CA will slowly break down today through Tuesday. Hgts today will be an impressive 596 dam and will slowly fall to 591 dam by Tuesday. The effects of these higher than normal higheights will be greatly mitigated by the strong onshore push both to the east (5 to 9 mb) and north (4 to 6 mb). There will be minimal day to day changes with the cloud cover where skies will be clear with the major exception of a night through morning low cloud pattern that will cover the csts and vlys. The strong onshore flow will make for slower than normal clearing and no clearing at many west facing beaches. The low clouds will also arrive earlier in the evening for the coastal areas. Max temperatures today and Monday will mostly be in the 70s across the coasts (mid to upper 60s beaches), with 80s and lower 90s in the valleys. These max temps are mostly 3 to 6 degrees below normal for this time of year. The Antelope Valley, however, with no marine influence will continue to see max temps from 100 to 105 each day which is 5 degrees above normal. The lower hgts on Tuesday will bring max temps down by 2 to 4 degrees at the csts and 3 to 6 degrees elsewhere. Lastly the strong push to east will bring gusty winds to the interior each afternoon and evening, especially the western Antelope Valley and foothills. Wind speeds will be close to advisory levels but likely just under with a few of the typical gusty locations seeing gusts to 45 mph. Long Term - Wednesday through Saturday 13/304 AM. For the long term period the upper pattern will become very weak with no synoptic scale features to speak of. Hgts will be near 590 dam through the period. At the surface the strong onshore flow will continue through Thursday, and may even become a mb stronger, before starting to weaken thursday night through Friday. The condtions for Wednesday and Thursday will be very similar to Tuesday. The night through morning low clouds and fog will continue unabated and the beaches will continue to struggle with clearing. Max temps will continue to run 3 to 6 locally 8 degrees below normal with highs only in the 80s across the vlys. Strong onshore flow will continue to bring gusty (likely advisory level) winds to some of the mountains as well as the western portions of the Antelope Valley and foothills. Both the GFS (Global Forecast System) and EC agree that starting Thursday evening and really ramping up Friday there will be a significant amount of moisture advecting in from the SSE at 700 mb and above. Yesterday both the GFS and EC were dry below 700 mb, but the 00Z run of the EC now shows significant moisture down to 850 mb. The NBM has little in the way of cloud cover forecast but would not be surprised is skies were at least partly cloudy. As of now, there is a 10 percent chance for monsoonal thunderstorms during the afternoon and evening hours Thursday through Sunday. Marine 13/404 AM. This afternoon and evening, localized Small Craft Advisory (SCA) W to NW winds may impact the waters around Point Conception south to the Channel Islands, and nearshore from Point Mugu to Pacific Palisades and through the San Pedro Channel. Expecting similar winds for the same areas Monday evening. Otherwise, relatively benign conditions will continue through Wednesday. More widespread SCA (Small Craft Advisory) level winds are possible Friday, focused on the outer waters. Night to morning patchy dense fog is possible through at least Monday.
