Area Forecast Discussion National Weather Service Los Angeles/Oxnard CA 401 PM PST Mon Jan 18 2021

SYNOPSIS. 18/202 PM.

There will be weak offshore flow today and temperatures will begin to cool down. Very strong northeast winds will affect the area late tonight through Wednesday morning, especially across Los Angeles and Ventura Counties. It will likely remain dry except for possible showers over the eastern San Gabriels on Tuesday. There will be a widespread chance for light rain Friday through the weekend.

SHORT TERM (TDY-THU). 18/202 PM.

Overall, 12Z models in very good synoptic agreement through the short term period. At upper levels, strong low will retrograde over the area Tuesday then southwest and south of the area on Wednesday and Thursday. Near the surface, moderate to strong offshore flow will continue.

Forecast-wise, main issue continues to be a strong Santa Ana wind event tonight through Wednesday morning. 12Z models do not indicate any major changes to previous forecast thinking with respect to the strength of the event. Offshore gradients will increase tonight/Tuesday then weaken slightly Tuesday night/Wednesday then weaken more noticeably on Thursday. On Tuesday morning, the LAX- DAG is forecast to range between -7.0 and -9.2 mb and between -6.5 and -7.5 mb on Wednesday morning. Just for reference, the 97th percentile LAX-DAG gradient is -6.8 mb. So, these forecast gradients are very noteworthy. Additionally, models continue to indicate very impressive upper level support (northeast winds 45-55 knots) with strongest winds Tuesday and Tuesday night. With strong offshore gradients and impressive upper level support, high confidence in a strong Santa Ana wind event. Will continue with current HIGH WIND WARNINGs from early Tuesday morning through Wednesday morning. Also, will issue WIND ADVISORIES leading into the current slate of warnings as well as issue WIND ADVISORIES for the Central Coast, Antelope Valley and interior sections of San Luis Obispo and Santa Barbara counties. Please refer to LAXNPWLOX for more detailed info about the plethora of wind products in effect. For Wednesday night and Thursday, the offshore winds will be much weaker, but still likely at advisory levels for many areas, especially Ventura and LA counties.

Otherwise, secondary issue continue to be the possibilty of some light showers as moisture wraps around the upper low. Models indicate the potential for some very light, scattered showers across the San Gabriel Mountains as well as the southern Inner Coastal Waters Tuesday and Tuesday evening. Will keep mention of slight chance showers for these areas with the afternoon forecast. Precipitation totals, if any, will be very light.

As for temperatures, Tuesday will be cooler for most areas as offshore winds bring in some significant cold air advection. The only exception will be coastal areas where the downsloping effect of the winds will bring some warming. On Wednesday, all areas will warm up with continued offshore flow and more limited cold air advection. On Thursday, expect some cooling most areas as weak onshore flow returns Thursday afternoon.

LONG TERM (FRI-MON). 18/202 PM.

For the extended, 12Z models have the same general synoptic idea through the period. At upper levels, low develops along the Northern CA coast on Friday then drop southward Saturday and Sunday with another trough moving across the area on Monday. Near the surface, weak onshore flow is forecast to prevail.

Forecast-wise, this will be a noticeable pattern change for the area. With the upper low dropping south, it will be able to pick up some moisture. So, there is the potential for some precipitation across the area Friday afternoon through Sunday morning. At this time, there could be some decent rainfall totals with this system. Preliminary QPF amounts range from 0.10 to 0.50 inches across San Luis Obispo, Santa Barbara and Ventura counties with 0.50 to 1.00 inch possible across LA county (with highest amounts over the foothills). For Monday, models differ a bit with the timing of the upper level trough, but still indicate the chance for some additional light precipitation.

As for temperatures, expect much cooler conditions through the extended with all areas well below seasonal normals.

AVIATION. 18/1824Z.

At 1657Z at KLAX, there was no marine layer. There was a surface- based inversion with a top at 1000 feet at 19 degrees C.

High confidence in CAVU TAFs. Moderate confidence in timing of gusty winds for KOXR, KCMA, and KVNY which could arrive 1-2 hours later than forecast tomorrow morning.

KLAX . High confidence in CAVU TAF. Good confidence that an east wind component will remain below 5kt through 09Z. Moderate confidence in gusty easterly winds developing after 15Z, which may occur 1-2 hours earlier than forecast.

KBUR . High confidence in CAVU TAF. There is a 30 percent chance of 15KT easterly winds 15Z-21Z.

MARINE. 18/956 AM.

High confidence that Small Craft Advisory (SCA) level hazardous seas over 10 feet will continue through Tuesday afternoon across the waters along the Central Coast southward to San Nicolas Island. There is also a 30% chance of SCA level northwest winds late this afternoon across the northern outer waters. High confidence that SCA level northeast winds will develop by late tonight and last through at least late Tuesday night north of Point Conception. There is a 30-40% chance that winds may exceed Gale force.

High confidence in gusty northeast winds and choppy short-period seas across all the inner waters inside the Southern California Bight and out to all the Channel Islands, San Nicolas Island, and Catalina Island late tonight through Wednesday morning. The strongest winds are expected Tuesday morning through afternoon. A Gale Watch is in effect from late tonight through Wednesday morning with winds likely peaking between 30 and 40 kt with local gusts to 50 kt. Choppy wind-generated waves of 5 to 8 feet are also expected. These conditions are expected to impact the eastern Channel Islands and Catalina Island. East facing harbors, such as Avalon Harbor and other east facing harbor entrances across the Channel Islands will be affected with strong winds and steep seas. These conditions are hazardous to boaters, and there may be damage to boats that are not anchored properly. Mariners should avoid these areas, or remain in safe harbor until conditions improve.

FIRE WEATHER. 18/400 PM.

Gusty offshore winds and low humidities will continue to bring elevated to brief critical fire weather conditions through early evening for Los Angeles and Ventura counties as well as the coastal foothills of San Luis Obispo County. Wind gusts will continue to range between 30 and 50 mph across these areas, with humidities in the 12 to 25 percent range.

A very strong and damaging northeast to east wind event is expected to impact a large portion of Southwest California late tonight through Wednesday morning. Red Flag Warnings are in effect for many portions of Southwest California later this evening through Wednesday morning. The strongest and most widespread winds are expected to be Tuesday through Tuesday night when widespread damaging wind gusts of 60 to 80 mph will be likely in the mountains, foothills, and some valley locations in Los Angeles and Ventura counties. Isolated gusts as high as 90 mph will be possible in the mountains of Los Angeles county. Even coastal areas (including portions of the LA Basin) will likely see locally damaging wind gusts of 50 to 65 mph. Portions of San Luis Obispo and Santa Barbara counties (especially the mountains,Central Coast, and Santa Ynez Valley) could see strong northeast to east winds Tuesday into Tuesday night, with wind gusts of 30 to 50 mph at lower elevations and 50 to 70 mph at higher elevations. Humidity levels tonight through Tuesday are expected to range between 12 and 25 percent across coastal and valley areas, and 15 to 30 percent across the mountains, with humidity levels gradually rising on Tuesday night.While humidity levels will be above 15 percent for some areas, the strength of this wind event and the current state of the very dry fuels warranted this Red Flag Warning issuance. Significant wind impacts will be likely with this event, including the threat of widespread downed trees and powerlines, as well as power outages. Winds are then expected to diminish Thursday through next weekend, with a chance of precipitation Friday and Saturday, and additional precipitation chances next week.
