| Area Forecast Discussion ...UPDATED National Weather Service Los Angeles/Oxnard CA 1017am PDT Tuesday September 22 2026 Short Term - Today through Thursday 22/936 AM. Ydy's upper low will morph into a weak and trough pos tilt trough today. Hgts will rise a couple dam to 582 dam. Most importantly, offshore trends will bring weak offshore flow from the north in the morning and much reduced onshore flow to the east in the afternoon. The first effect of these gradients (as well as the lack of lift compared to ydy with the upper low overhead) will be a dramatic reduction in the amount of morning low clouds. The next will be a 2 to 4 degrees warm up across the area (3 to 6 degrees for the Central Coast). Despite this warming most max temps will end up 3 to 6 degrees under normal. Breezy but sub-advisory northwest winds are probable this evening for wind prone areas of southwest Santa Barbara County. Wednesday will be the warmest day of the next 7 as a little Probability of Precipitation up ridge arrives overhead. There will be weak offshore flow from both the east and the north in the morning and only weak onshore flow in the afternoon. There will be very limited morning low clouds mostly confined to the SBA county west coast. Total sunshine, offshore flow in the morning and the ridge will all combine to warm max temps 8 to 12 degrees. This warming will bring 80s to the csts and 90s to the vlys with a moderate risk of heat exhaustion. On the plus side, a dry airmass and light winds will allow for good evening to overnight temperature recoveries, limiting heat impacts and NO need for heat products. The max temps are about 5 degrees above normal for areas south of Pt Conception but are 10 degrees above normal for the Central Coast. AVDAFDLOX Thursday weak trough.ing and a return to onshore flow will result in an increase morning low clouds across the csts as well as a 2 to 4 degree cool down. Max temps, still, will end up 2 to 4 degrees above normal (4 to 8 across the Central Coast). Long Term - Friday through Monday 22/936 AM. On Friday Srn CA will be sandwiched between a decent sized trough to the north just off the WA coast and a large upper high over TX. This will result in dry SW flow over the Srn CA. Hgts will be near 584 dam. This pattern will be fairly stagnant and will last through Sunday. At the surface fairly AVDAFDLOXweak onshore flow will persist except in the mornings where there will be weak offshore flow from the north. The weather will be pleasant and benign with low clouds across the some of the csts (esp the western SBA county cst), but otherwise mostly clear skies. Most max temps will cool a little Friday and Saturday. The best cooling will be north of Pt Conception where the trough will have the greatest effect. Even with this cooling max temps will remain a few degrees over normal. Blended ensemble guidance still shows 4 to 8 degrees of cooling on Sunday, which now seems a little more reasonable as now a sharper trough with falling hgts will likely move into the state. Still the amount of cooling may be overdone esp over LA county. Weak ridging and building offshore flow from the north builds in on Monday. There is a 50-60 percent chance of weak offshore flow from the east in the morning as well. Look for a mostly sunny day with some warming esp across the Central Coast. Breezy northerly winds are possible for prone interior areas to the Santa Ynez mountain range. Distant tropical cyclones to the SSW may send another round of swells and large surf and dangerous rip currents to south or southwest facing coasts by late this weekend (see Beaches section below for additional information. There is also a good chance of some increasing mid to high clouds well ahead of these systems. The deepest tropical moisture will likely be shunted to our east through the period with only a 5-10 percent chance that deep enough moisture makes it far enough north for showers focused across LA to maybe Ventura Counties early next week. Marine 22/939 AM. Good confidence in Small Craft Advisory (SCA) west to northwest winds increasing in the afternoon hours today into early Wednesday morning across the Outer Waters. These winds will reach into the nearshore waters along the Central Coast and the Santa Barbara Channel this afternoon/eve. 30% chance that advisories across the outer waters (PZZ670/673) will need to be extended into Wednesday afternoon/eve. SCA (Small Craft Advisory) winds may return as early as Thursday evening across the Outer Waters with increasing chances Friday into the weekend, along with a low to moderate potential of reaching into portions of our inner waters. Beaches 22/939 AM. The eastern pacific is currently active with hurricane Polo, tropical storm Odalys and a developing disturbance southeast of Hawaii. This activity will produce southerly swells (SW-SE) which will impact the southern california coastline as early as Friday into the weekend, with better chances early next week. Confidence is currently low on the evolution of these systems and the maginitude and exactly how the swells will propagate. Stay tuned for future updates as we continue to monitor these storms.
