| Area Forecast Discussion National Weather Service Los Angeles/Oxnard CA 327am PST Monday Jan 19 2026 Synopsis 19/314 AM. High pressure and offshore flow will bring warm and dry conditions through midweek along with gusty northeast winds at times across Los Angeles and Ventura Counties. A significant cooling trend is expected to begin Wednesday, with minor light rain or drizzle possible Thursday and Friday. Short Term - Today through Wednesday ...19/255 AM. No big changes to the short term with this forecast package. Breezy offshore flow and dry weather will continue through Tuesday, with one last hurrah for Santa Ana winds on Tuesday morning with this seemingly never ending period of offshore flow. While offshore gradients are nearly the same or have weakened compared to yesterday, paired with lowering 500 mb heights, a little bit of cooling will be possible today compared to yesterday. Then, offshore gradients strengthen again tonight into Tuesday morning bringing a slight increase in winds (compared to this morning), and maybe a few favored mountain locations will have some isolated advisory level gusts. Otherwise, temperatures will be about the same today and Tuesday with highs ranging around 70s to low 80s (still 10-15 degrees above normal for this time of year). On Wednesday, the ridge of high pressure that's been over the west coast these past few days will finally break down, bringing a drop in 500mb heigheights and a reverse to onshore flow (finally) ahead of a weak low pressure system that will move into the area later this week. Wednesday will see a widespread 4-8 degree drop in high temperatures for coast and valleys, with the highest drop near the coasts. Long Term - Thursday through Sunday 19/318 AM. The cooling trend will continue through at least Friday as a low pressure system around 560 dam, will move about 150 mb SW of SoCal. This system will be pretty weak in terms of rain, with light rain showers or drizzle possible Thursday through Friday, mainly for areas south of Point Conception. However, as this system doesn't have a ton of moisture with it, rainfall totals of around 0.10 inches or less is expected. The lowering heigheights and lack of significant offshore flow will lead to at least a 3 day cooling trend with coast and valley max temps falling from the lower to mid 70s Wednesday to the mid to upper 60s on Friday. Marine layer stratus will likely redevelop and will affect portions of the coast through the period. Aside from the low clouds, skies will be partly cloudy Thursday and Friday. As for Saturday and Sunday, weather those days seem fairly benign so far, as both EC and GFS (Global Forecast System) suggest a return to weak offshore flow and increasing 500 mb heigheights once again. The famous pair of offshore flow and increasing 500mb heigheights will likely lead to widespread warming of 2-5 degrees each day. Both the EC and GFS ensembles and their AI equivalents suggest rain the last few days of the month and possibly into the beginning of the new month, but the timing has been pushed back and amounts have seemed to lightened over the past 3 runs or so. Marine 19/140 AM. High confidence in conditions remaining below Small Craft Advisory (SCA) levels through Wednesday, with moderate confidence through Friday. Peak gusts of 15-20 knots are possible through later this morning for the western Channel Islands to Point Conception with just a 10 percent chance of reaching SCA (Small Craft Advisory) levels. Localized northeast Santa Ana wind gusts of 20-25 knots may occur at times Monday afternoon through Tuesday afternoon between Ventura and Santa Monica (and potentially out to Santa Cruz and Anacapa Islands). Highest chances (40-60% chance) exist Tuesday morning to early afternoon. Patchy dense fog with visibilities less than 1 NM may impact the coastal waters at times into next week, but low confidence in timing and location of fog.
