Area Forecast Discussion . UPDATED National Weather Service Los Angeles/Oxnard CA 1108 AM PST Fri Nov 27 2020

updated aviation and fire discussions

SYNOPSIS. 27/532 AM.

Gusty offshore winds will persist over the region into Sunday with the strongest winds occurring over portions of Ventura and Los Angeles counties through this afternoon. Temperatures will warm slightly through Wednesday then will cool at the end of next week.

SHORT TERM (TDY-SUN). 27/828 AM.

The LAX-DAG pressure gradient at 16Z was -5.1 mb (down 2.1 mb in 24- hours), and the LAX-BFL gradient was -3.8 mb (up 1.1 mb in 24- hours). These moderate to strong offshore gradients combined with good upper level support has kept strong and gusty NE winds over much of VTU/L.A. Counties this morning, especially in the foothills and mtns. The strongest gusts as of 7 AM included 65 mph at the Mill Creek RAWS, 58 mph at SCA Sierra Pelona West, and 56 mph at SCE Magic Mtn Truck Trail. With the morning sunshine there should be mixing down to lower elevations with higher gusts close to 60 mph possible in the foothills adjacent to the vlys, and gusts to 45 mph or more over the coastal areas from Oxnard to Malibu. High Wind Warnings and Wind Advisories remain in effect for these areas into this afternoon. Please see the latest Non- Precipitation Weather Message (LAXNPWLOX) for further details. In addition, a very dry air mass with humidities in the single digits and teens will prevail across the area today. This combined with the strong and gusty winds will continue critical fire weather conditions over a large portion of VTU/L.A. Counties today and Red Flag Warnings will continue. Please see the Fire Weather Discussion below for further details.

Sunny skies will prevail across the forecast area today. High temps are expected to warm to a few degrees above normal for many areas S of the mtns, and to near normal to a few degrees below normal for the mtns and deserts. The warmest vlys and coastal areas should reach the low to mid 70s this afternoon.

An upper level low over AZ this morning will move E into New Mexico this afternoon. This will allow upper level ridging to build into the forecast area with H5 heights increasing to around 575-576 dm by late today. This weak upper level ridging will continue over the forecast area tonight and Sat, then a weak 575 dm upper level trof will move into the area Sat night before another weak pop-up ridge moves in for Sun with H5 heights around 576-577 dm.

Good offshore pressure gradients to the N and E will continue tonight into Sat morning, with the NAM predicting the 12Z Sat LAX- DAG gradient to be -5.6 mb, and LAX-BFL to be -2.9 mb. These gradients will help to support another round of gusty NE winds across portions of VTU/L.A. Counties tonight into Sat morning, but the upper level support will diminish enough that Advisory level winds should be more localized. Still, some wind gusts could still be around 45 mph in the windiest mtn and foothill locations. Otherwise, most of the wind-prone areas should see winds in the 15 to 30 mph range during the period.

Mostly clear skies will continue tonight through Sun. Daytime temps will turn a few degrees warmer each day through the weekend. Highs will be several degrees above normal for all areas by Sun, with readings in the 70s for much of the coast and vlys. Nighttime temps will turn quite cold in wind-sheltered locations over the weekend. It looks like frost will be possible in the interior vlys, the Ojai Vly, and possibly even some inland coastal areas of SLO/SBA Counties. It looks like Frost Advisories may be needed for some of these areas.

LONG TERM (MON-THU). 27/534 AM.

Offshore flow will likely continue across the region Mon thru Thu. The ridge across the area will flatten a bit Mon as a trough pushes into the Pac NW. Then, the models show the trough digging on Tue to various degrees. The EC shows it evolving into a strong upper low over the Four Corners area, while the GFS shows a larger upper low across the Plains states. Meanwhile, both show a highly amplified upper ridge developing just off the West Coast. The EC maintains offshore flow the entire time, while the GFS shows flow turning negligibly onshore Tue afternoon. Either way there could be some gusty northeast winds through and below passes and canyons during the night/morning hours Sun night thru Tue (below advisory levels). Max temps should be a few degrees above normal, but it will be chilly at night, especially in wind sheltered locations.

Beyond Tue, the models show major discrepancies and are a having a very difficult time resolving the development and movement of multiple upper lows across the country and another one approaching the West Coast by Thu. The GFS is extremely aggressive with its offshore gradient on Thu, with the gradient table showing a gradient of -9.4 mb at 12Z between KLAX and KDAG. That seemed out of line, but a look at its surface pressure map verified it. The EC shows much more modest gradients Wed/Thu. At this point, expect mostly clear skies and dry weather to continue, with some possible cooling, at least for Thu as heights/thicknesses lower. There will likely be gusty winds at time, with the potential for a significant wind event if the operational run of the GFS is correct.

AVIATION. 27/1906Z.

At 1811Z at KLAX, there was no marine layer nor an inversion.

High confidence in all CAVU TAFs. Light to moderate turbulence is likely over and near higher terrain through 23Z. LLWS up to 10 kt is possible as well.

KLAX . High confidence in CAVU TAF. No significant east wind is expected.

KBUR . High confidence in CAVU TAF. Light to moderate turbulence with up to 10 kt of LLWS is possible through 23Z.

MARINE. 27/827 AM.

Seas have started to subside across the northern outer waters, so have decided to expire the Small Craft Advisory (SCA) over PZZ670. Otherwise moderate confidence that SCA level seas will continue across the outer waters from Point Conception to San Nicolas Island through this afternoon with a chance they may subside earlier. For the waters inside the Southern California Bight, moderate confidence in SCA level NE winds through early this afternoon from Point Mugu to Santa Monica likely remaining close to shore. There will be steep, short-period seas across these waters through the afternoon

High confidence that winds and seas will be below SCA criteria on Sunday. There is a chance of SCA level winds on Monday and Tuesday for the outer waters from the Central Coast to San Nicolas Island.

FIRE WEATHER. 27/950 AM.

Strong and gusty northeast winds will continue across the area into early this afternoon, strongest over Los Angeles and Ventura counties. The offshore winds will weaken later today, but remain breezy in many areas into Saturday. Wind gusts of 40 to 60 mph are expected over Ventura and much of Los Angeles Counties this morning, strongest over the most wind-exposed foothills and the mountains. Minimum humidities are expected to be in the 5 to 15 percent range in many areas today and Saturday, with very poor overnight recoveries. Red Flag Warnings conditions are expected to continue across Los Angeles and Ventura Counties except for the Antelope Valley through early this evening, when the winds begin to ramp down. However, the winds are expected to increase again some later tonight into Saturday, with minimum humidities remaining very low, in the single digits to mid teens. As a result, the secondary Red Flag criteria are expected to be met tonight through early Saturday evening for the Los Angeles and Ventura mountains and windiest valleys (Santa Clarita and Ventura Valleys) and the Red Flag Warning has been extended for these areas through 6 PM Saturday.

Mild temperatures will persist through the weekend, with highs generally between 65 and 75 degrees. Northeast wind gusts of 20 to 35 mph are also expected over the wind prone areas of Santa Barbara and San Luis Obispo Counties at this time as well, resulting in elevated to brief critical fire weather conditions. Dry air will persist across the area through next Thursday, with gusty north winds possible Monday night into Tuesday. There is a growing potential for moderate Santa Ana winds and possible ed Flag conditions developing over Los Angeles and Ventura Counties sometime between Wednesday and Thursday.

LOX WATCHES/WARNINGS/ADVISORIES. CA . Wind Advisory in effect until 3 PM PST this afternoon for zones 40-41-547. (See LAXNPWLOX). High Wind Warning in effect until 3 PM PST this afternoon for zones 44>46-53-54-88. (See LAXNPWLOX). Red Flag Warning in effect until 6 PM PST this evening for zones 240-241-547-548. (See LAXRFWLOX). Red Flag Warning in effect until 6 PM PST Saturday for zones 244>246-253-254-288. (See LAXRFWLOX). PZ . Small Craft Advisory in effect until 3 PM PST this afternoon for zones 655-673-676. (See LAXMWWLOX).

.HAZARD POTENTIAL OUTLOOK (SUN-THU).

An extended dry and warmer pattern is expected Saturday through Monday with persistent elevated fire weather conditions. Another strong Santa Ana wind event is possible next Wednesday and Thursday.
