Area Forecast Discussion . UPDATED National Weather Service Los Angeles/Oxnard CA 1056 PM PDT Fri Oct 15 2021

updated aviation discussion

SYNOPSIS. 15/808 PM.

Santa Ana winds will bring continued warm and dry conditions to Southwest California through Saturday. By Sunday, winds will switch back to onshore with cooler temperatures and higher humidities. A deepening marine layer with coastal low clouds and fog is expected to return early next week, bringing more seasonable temperatures to the area.

SHORT TERM (FRI-MON). 15/915 PM.

***UPDATE***

Moderate Santa Ana winds brought very warm and dry with Red Flag conditions across Los Angeles and Ventura counties today, with similar conditions expected on Saturday. The LAX-DAG offshore pressure gradient peaked this morning at -5.6 mb, with the highest wind gust reaching 59 mph this afternoon over the L.A. County mountains. Santa Ana winds are now focused on the area from the I-5 cooridor through the Santa Clarita Valley to the Santa Monica Mountains. The Ventura County Coast got some relief from the dry, warm air with a decent late afternoon sea breeze, but remaining areas with the Santa Ana winds had relative humidities below 15%. Offshore winds are expected to remain gusty overnight, primarily affecting wind prone areas of Ventura and LA Counties, as well as the Santa Lucia mountains in San Luis Obispo county.

Overnight lows tonight will be quite warm in the foothills and windy areas, remaining in the 70s. Minor adjustments were made to the forecast, and temperatures were decreased a few degrees for interior San Luis Obispo County as values there appeared a bit too warm given what happened today.

***From Previous Discussion***

Santa Ana winds brought red flag warning conditions to most of Los Angeles and Ventura Counties today. Widespread humidities less than 15 percent and gusty east to northeast winds of 25-45 mph have been common. A few foothills wind sensors peaked between 50-55 mph before noon. Temperatures warmed well into the 80s in the windier corridors with a few 90+ readings from Lake Casitas to Camarillo in Ventura Co. and near 90 degrees around the Long Beach area. For tonight, many breezier foothills in eastern Ventura County and western LA County may remain well above 70 degrees for minimum temperatures along with 10 percent humidity, a significant fire weather risk at nighttime.

East to northeast winds will likely increase late tonight for the typical Santa Ana corridors, but also downslope of the Santa Lucia Mountains in western San Luis Obispo County. Wind advisories will remain in effect for most areas through midday on Saturday. Computer model data continues to show upper level wind support a little stronger in the morning compared to today, along with surface pressure gradients nearly the same at -5mb for LAX-DAG. Temperatures and humidities will have a head start for reaching their peak/trough, respectively on Saturday. Fire starts are more concerning due to the duration of very low humidities and winds tomorrow. Many temperatures will be at least as warm as today with highs 85-95 degrees for valleys and coasts in Ventura and Los Angeles Counties.

Winds will reverse to onshore at coastal areas late Saturday afternoon and evening, then continue to advance more humid air into the valleys Saturday night. The mountains and deserts will continue to see poor overnight recoveries and rather dry conditions extending into Sunday afternoon. For the coast side of the mountains, Sunday will be a much cooler day with afternoon seabreezes. By Sunday night, an upper trough swings across northern CA with a cold front sliding through the central coast. The ability of this front to hold together and bring anything more than a few light sprinkles of rain to the SLO County coast early Monday morning is highly unlikely. The main effect will be a stronger onshore push of low clouds and patchy drizzle in the morning with more seasonal temperatures.

LONG TERM (TUE-FRI). 15/122 PM.

Model deterministic runs and ensembles are coming into better alignment for a ridge to pop back up across CA beginning Tuesday with heights pushing 585dm by Thursday. There are at least weak offshore pressure gradients showing up (-2.7mb on ECM) on Thursday and anything stronger could contribute significantly to downslope heating and drying. That leads to uncertainty in the temperature forecasts with model data ranging from 75 to 90 degrees potentially for some coastal zones. For the most part, expect a shrinking marine layer for beach areas with temperatures climbing back above normal during the week and humidities dropping again. A peak in temperatures on Thursday looks reasonable.

The greatest uncertainty in the forecast comes toward the end of next week and the following weekend. The ridge will breakdown and slide east beginning Friday with a weakening cold front approaching the area late Saturday (Oct 23). Ensemble runs have indicated many members with precipitation on Sunday into Monday, however, newer runs have shown much drier scenarios due to the location of a large trough over the eastern Pacific. Trends in the ensembles are for a weaker part of the trough to pass through southwest CA, kind of a glancing blow. Then the trough digs well out over the central Pacific which will likely force the jet stream well to our north (get used to this sentence as La Nina will help repeat this pattern all winter). The bottom-line is that we might get a little precipitation late next weekend, but it doesn't look like it will amount to much and will have minimal impacts on our current fire season.

AVIATION. 16/0555Z.

At 0503Z at KLAX, there was no marine layer. There was a surface- based inversion with a top around 800 feet at a temperature of 26 degrees C.

High confidence in CAVU TAFs with moderate confidence in wind speed for Santa Ana winds through 21Z. There is a chance of LLWS and moderate turbulence for LA/Ventura County TAF sites through 21Z, especially around higher terrain. There is a 20% chance of restricted visibility at KSBA due to smoke from the Alisal fire.

KLAX . High confidence in CAVU TAF. Any east wind component should be less than 7 knots.

KBUR . High confidence in CAVU TAF. There is a chance of LLWS and moderate turbulence through 21Z.

MARINE. 15/952 PM.

From Ventura to Santa Monica and out to the Channel Islands, northeast Santa Ana winds close to shore will increase this morning and peak before noon. Small Craft Advisories (SCAs) will be in effect starting at 3 AM Saturday for these winds. The strongest winds will likely be closest to shore. While there is a chance that these winds will affect Santa Catalina Island including Avalon Harbor, moderate confidence that any winds that form there will be less than 15 knots.

Otherwise, not expecting SCA conditions across the coastal waters through Sunday night. For Monday and Monday night, northwest winds will strengthen across the waters with moderate confidence in SCA level winds returning to the outer waters off the Central Coast to San Nicolas Island, and possibly to the east Santa Barbara Channel. Winds and seas are then expected to be below SCA levels for all coastal waters Tuesday and Wednesday.

LOX WATCHES/WARNINGS/ADVISORIES. CA . Wind Advisory in effect until noon PDT Saturday for zones 40-41-44>46-53-54-88-547. (See LAXNPWLOX). Red Flag Warning in effect until 8 PM PDT Saturday for zones 240-241-244>246-253-254-288-547. (See LAXRFWLOX). PZ . Small Craft Advisory in effect from 3 AM to 3 PM PDT Saturday for zones 650-655. (See LAXMWWLOX).

.HAZARD POTENTIAL OUTLOOK (MON-FRI).

Gusty northerly winds may occur across southern Santa Barbara County and the Interstate 5 Corridor on Sunday night and Monday.
