Area Forecast Discussion ...UPDATED National Weather Service Los Angeles/Oxnard CA 1005pm PST Wednesday Jan 22 2025 Synopsis 22/138 PM. Warm and dry conditions will continue through Thursday as another Santa Ana pattern develops. Gusty northeast winds will develop today and peak overnight tonight and into Thursday morning. A significant cooling trend will begin Friday and continue through the weekend as a cold storm system moves over the region. Showers are expected off and on through Monday morning with mountain snow above 3000 to 4000 feet. Short Term - Wednesday through Saturday 22/813 PM. ***UPDATE*** Good hgt rises and moderate offshore flow brought 8 to 12 locally 14 degrees of warming to the area. This unfortunately really lowered humidities and created (along with the NE winds) a dangerous fire environment which led to the explosive growth of the Hughes fire. This fire has produced quite a bit of smoke which has been carried by the Santa Ana wind to much of southeastern VTA county and southwestern LA county. The wind forecast is on track with a steady increase in the NE winds slated to start around 9pm and continue through 10am Thursday. The peak of the winds will be around 9am Thursday. This tracks with the gradient forecast which calls for an offshore push from the east near 9 mb just after sunrise. Pretty much a classic Santa Ana directional pattern with the axis of strongest winds in a line from the Santa Clarita Valley to Leo Carillo Beach. The forecast was updated for tomorrows temperatures which should be a little cooler than today's rather robust values. ***From Previous Discussion*** Quick update to the forecast to add areas of smoke across Los Angeles and Ventura Counties from the Hughes Fire. No other changes. Santa Ana winds have returned to LA/Ventura Counties and expected to really kick into gear later tonight into Thursday. Wind advisories and warnings are in effect for all the usual Santa Ana areas. As usual this does not include most of the LA metro area or the San Gabriel Valley. So far winds have mostly been at or below advisory levels with just a couple sites in the mountains reporting 50+ mph winds. As gradients and upper support increase, especially after midnight tonight into Thursday morning, winds will increase as well peaking in the 60-65 mph range in the mountains and up to 50 mph in the valleys and Oxnard plain. Gusty east winds also expected through the Santa Lucias in SLO County but mostly under 35 mph. Winds expected to slowly taper off through the afternoon Thursday and evening, though given the strong gradients in the morning some wind hazards, particularly across inland areas, may need to be extended beyond the current 2pm expiration. Temperatures today have climbed to the 70s to lower 80s. Expecting one more day of well above normal temperatures and even a few degrees warmer with a few areas in the mid 80s. This would be roughly 15-20 degrees above normal across coast and valleys. Gradients will quickly turn onshore Friday, resulting in a much cooler day for coast and valleys, likely dropping back into the 60s to lower 70s. May still have some local northeast winds in the valleys and mountains early Friday before onshore flow kicks fully into gear Friday afternoon. On Saturday a cold upper low will be dropping south through California and be centered somewhere in the vicinity of the Bay Area Saturday afternoon. As the low continues its track to the south, shower chances will be increasing across the area. Most of the ensemble solutions indicate showers holding off until later in the afternoon or even into Sunday morning, but cutoff lows are very difficult to predict the movement of and the timing could be off by several hours or more. Snow levels will be lowering and if showers start Saturday there could be snow down to 4000 feet by evening, possibly leading to light snow accumulations in the higher portions of the Eaton fire as well as the Tejon Pass on Interstate 5. Temperatures Saturday will be much cooler with highs in the 50s to lower 60s for coast and valleys. Long Term - Sunday through Wednesday 22/235 PM. The upper low is expected to remain in the vicinity of southwest California through at least Sunday night and possibly into Monday. Ensemble solutions have been pretty consistent showing the best chances of showers later Saturday into Sunday. Given the location of the upper low, the most favorable area for precipitation will be across the eastern portion of the San Gabriel mountains and the adjacent foothills as that is where the best forcing and upslope flow will be. While showers will mostly be on the lighter side, under a quarter inch per hour, the longer duration of showers across the eastern San Gabriels from late Saturday through early Monday will allow rain totals be higher there than other areas, possibly an inch or more. Rain totals expected to taper off to a half inch or less west of LA County. With the upper low overhead there is still a chance of thunderstorm or two across the area with rain rates around a half inch per hour. If this happens over a burn scar it could initiate a debris flow but the chances of that happening are only 5-10%. Snow accumulations could reach 4-8 inches in the eastern LA mountains and will have to consider a winter weather advisory as we get closer. Lower snow amounts expected to the west of LA County. Dry conditions expected Tuesday through Wednesday. There are a few ensemble solutions showing some offshore winds next week but chances are under 20%. Marine 22/1005 PM. In the Outer Waters, SCA (Small Craft Advisory) level NE winds are expected (70% chance) in the southern zone (PZZ676) from this evening thru Thu afternoon.

In the southern zones (PZZ673/676), SCA (Small Craft Advisory) level seas are likely Sat into Sun, with a 30% chance of SCA (Small Craft Advisory) level winds. In the Inner Waters off the Central Coast, there is a 20% chance for local SCA (Small Craft Advisory) conditions near Morro Bay late tonight. Then SCA conditions are not Thursday thru Fri night. SCA (Small Craft Advisory) level seas are likely (60% chance) Sat/Sat night. For the Inner Waters S of Pt. Conception: From Ventura/Oxnard to Malibu and out to Anacapa and E Santa Cruz Island, SCA (Small Craft Advisory) level NE winds will continue.

Elsewhere, there is a 30% chance of SCA (Small Craft Advisory) level NE winds late tonight/Thu morning.
