Area Forecast Discussion . UPDATED National Weather Service Los Angeles/Oxnard CA 1016 PM PDT Mon Jul 6 2020

updated aviation discussion

SYNOPSIS. 06/1013 PM.

Temperatures will be a little cooler Tuesday and Wednesday, especially for areas that see more coastal clouds. Gusty Sundowner winds will continue into early Tuesday morning. High pressure will build over the region later this week, bringing another warming trend for the weekend.

SHORT TERM (MON-THU). 06/808 PM.

***UPDATE***

Clear skies covered the forecast area early this evening. Some Low clouds were noted along and off the San and Orange County coast early this evening. There will be an eddy spinning up over the SoCal Bight overnight which should help to expand and spread these low clouds into the L.A. County coast later tonight. Patchy low clouds may form late tonight along the SBA County Central Coast as well. Otherwise, the clear skies will prevail across the region thru the night.

Northerly pressure gradients along the SBA County S coast were decent, with SBA-SMX at -3.8 mb at 03Z. These gradients were strong enough to produce north wind gusts up to 46 mph at the Gaviota RAWS and 42 mph at the Refugio RAWS early this evening. A Wind Advisory is in effect for the SBA County S coast and Santa Ynez Mtns thru 3 AM Tue, with these gusts persisting west of Goleta. Please see the latest Non-Precipitation Weather Message (LAXNPWLOX) for further details on the gusty winds.

***From Previous Discussion***

Sundowner winds are expected to reach wind advisory criteria west of Goleta this evening/night with isolated gusts to 50 mph near Gaviota. Locally gusty to 30 mph will be possible along the ridges toward San Marcos Pass later this evening. A few hours of humidities into the upper teens and lower 20s could result in elevated fire weather conditions for the SBA south coast (refer to fire discussion below).

Tuesday will be just a few degrees cooler than today as the temperatures trend lower through Wednesday. After morning coastal stratus and fog, expect another sunny day with the hottest conditions remaining over the interior valleys. The onshore LAX- DAG pressure gradient peaks over 8 mb on Wednesday afternoon, and the heights will lower slightly allowing a deeper marine layer and therefore more widespread low clouds for coastal areas by Wednesday morning. Similar conditions will persist into Thursday before the four-corners high pressure system begins to expand westward across southwest CA. Temperature trends will begin to reverse direction and move upward then.

LONG TERM (FRI-MON). 06/111 PM.

High pressure continues to build over southwest CA late in the week and looks likely to persist well into next week. By Friday, heights build to 594dm with the heat expanding back into the interior valleys and mountains. High temperatures are likely to push into triple digits in the Antelope Valley by Friday. Even warmer temperatures look reasonable for the weekend with lower to mid 90s downtown, near 100 for valleys, 105 for the AV, and even 90 degrees near Camarillo. The ongoing maximum temperature forecasts were pushed just slightly above model guidance numbers and this remains on-track as heights exceed 597dm over southern CA during this timeframe. Latest heat risk calculations indicate moderate to high categories across parts of the Ventura Co. valleys and a larger portion of LA County over the weekend. At least heat advisories may be needed or considered. Another interesting development is the first indication of monsoon flow moving through Mexico with a few thunderstorms possible near the border by Saturday afternoon. All deterministic and ensemble model data show a decrease in temperature trends, although still hot early next week. A notable southwest flow aloft during this time would also shunt any monsoon moisture well to our south and east. This is the time of year to see afternoon cumulus and possible monsoon storms over the mountains and deserts, so pay attention to the latest forecasts for this type of development.

AVIATION. 06/2358Z.

At 2330Z, the marine inversion at KLAX was based at 900 feet. The top of the inversion was 2300 feet with a temperature of 27 degrees Celsius.

Overall for the 00Z TAF package, moderate confidence in coastal sites and high confidence in valley/desert sites. Overnight, moderate confidence in return of IFR/LIFR conditions to KSMX as well as LA Basin sites (KLAX/KLGB/KSMO), but low confidence in timing. For other coastal sites, there is a slight chance of CIG/VSBY restrictions tonight. Otherwise, VFR conditions will prevail thru Tue afternoon.

KLAX . Overall, moderate confidence in 00Z TAF. High confidence in VFR conditions through this evening. Overnight, moderate confidence in return of IFR restrictions, but low confidence in timing (could be +/- 3 hours of current 12Z forecast). Otherwise, VFR conditions will prevail thru Tue evening.

KBUR . High confidence in 00Z TAF as CAVU conditions are expected through TAF period.

MARINE. 06/815 PM.

For the Outer Waters, moderate to high confidence in current forecast. For PZZ670/673, high confidence in Gale force winds through tonight. For Tuesday through Saturday, high confidence winds remaining at Small Craft Advisory (SCA) levels. There is a 40% chance that the Gale winds may continue through Tuesday night. For PZZ676, high confidence in SCA level winds continuing through Saturday.

For the Inner Waters north of Point Sal, high confidence in current forecast. SCA level winds will continue through Wednesday night with the strongest winds during the afternoon and evening hours. After a lull on Thursday, there is a 60% chance of SCA level winds once again Friday and Saturday during the afternoon and evening hours.

For the Inner Waters south of Point Conception, moderate to high confidence in current forecast. For a majority of the area, high confidence in winds and seas remaining below SCA levels through Saturday. The only exception will be the western half of the Santa Barbara Channel where there is a 70% chance of SCA level winds through tonight then a 50% chance of SCA level winds late Tuesday afternoon through Tuesday night. After a lull on Wednesday/Thursday, there is a 50% chance of SCA level winds again on Friday/Saturday during the late afternoon through overnight hours.

Patchy dense fog, with visibility 1 nautical mile or less, will affect the waters south of the Channel Islands late tonight and Tuesday morning.

There will be dangerous steep seas across much of the waters through Wednesday night.

FIRE WEATHER. 06/821 PM.

Locally gusty southwest to northwest winds (gusting between 25 and 40 mph) will continue across interior sections through this evening, strongest in the Antelope Valley. Warm and dry conditions are also expected to linger through the nighttime hours in the foothills and mountains. The combination of warm temperatures, low humidities, locally gusty winds, and drying fuels will continue to bring elevated fire weather conditions to interior areas through this evening, including the Soledad Fire burn area. The rapid fire spread seen yesterday afternoon and evening across the Soledad Fire (near Agua Dulce) are indicative of the large fire growth potential across interior areas.

Elevated fire weather conditions are also expected through this evening across the western portions of the Santa Barbara south coast and adjacent foothills. These areas can expect gusty sundowner winds, mainly from Gaviota to San Marcos Pass, with gusts of 35 to 45 mph this evening. The sundowner wind conditions will also bring warm and dry conditions, with humidities lowering into the teens and 20s across foothill areas.

A cooling trend is expected Tuesday through Wednesday as a weak upper level trough of low pressure passes to the north and onshore pressure gradients increase. Despite the cooling trend, interior areas will continue to see humidities between 10 and 20 percent along with onshore wind gusts between 25 and 40 mph, with isolated gusts as high as 45 mph in the foothills of the Antelope Valley. Hotter and drier conditions are expected to return to the region Friday through Sunday, with the potential for triple digit temperatures across warmest interior areas. This in combination with gusty onshore winds during the afternoon and evening hours will likely bring elevated fire weather concerns Friday through Sunday across interior areas.

LOX WATCHES/WARNINGS/ADVISORIES. CA . Wind Advisory in effect until 3 AM PDT Tuesday for zones 39-52. (See LAXNPWLOX). PZ . Small Craft Advisory in effect until 9 PM PDT Wednesday for zone 645. (See LAXMWWLOX). Small Craft Advisory in effect until 3 AM PDT Tuesday for zone 650. (See LAXMWWLOX). Gale Warning in effect until 3 AM PDT Tuesday for zones 670-673-676. (See LAXMWWLOX).

.HAZARD POTENTIAL OUTLOOK (THU-MON).

Hot temperatures will return to sections of the coastal and interior valleys of southwest California Saturday through Monday. Moderate to high heat risk will be possible.
