Area Forecast Discussion . UPDATED National Weather Service Los Angeles/Oxnard CA 1106 PM PDT Sat Aug 8 2020

SYNOPSIS. 08/908 PM.

Near to above normal temperatures are expected across Southwest California Sunday through Monday, with slight cooler temperatures Tuesday, and additional warming at the end of the week. Low clouds and fog will persist over coastal sections during this time, otherwise clear skies are expected.

SHORT TERM (SAT-TUE). 08/734 PM.

***UPDATE***

An upper trough over the region will weaken some overnight, and the surface pressure gradient from LAX to Daggett is very slightly weaker than yesterday at this time. This adds up to a persistence forecast for marine layer coastal clouds for tonight into Sunday morning. However, the NAM shows a coastal eddy spinning up over the San Pedro Channel later tonight, which should help to bring low clouds into the LA Basin whereas last night there were none. Otherwise, expect low clouds along the Central Coast and the western Santa Ynez Valley, and over the western Ventura Coast, west of Camarillo. The SBA South Coast should see some patchy low clouds after midnight, but this is a lower confidence forecast. Winds tonight are mainly light, except for gusts 30 to 40 mph in the Antelope Valley between Poppy Park and Lake Palmdale.

Expect slightly warmer temperature Sunday, and slightly lower humidities. Otherwise, little change expected for the area.

***From Previous Discussion***

The very weak upper level low, currently spinning over northern California, will get pushed to the west Sunday through Tuesday by an upper level high expanding over northern Mexico. This will bring some warming to the region tomorrow with very little change through Tuesday. Temperatures should push back up to normal, especially over the mountains and valleys where daytime temperatures between 90 and 100 are expected in the warmest spots. Coastal plains and nearest valleys will continue to be driven by the ebbs and flows of the marine layer, which continues to be on a frustratingly unpredictable bent. Still expecting temperatures to generally be higher in these areas, but the trends will be more of a mixed bag in space and time. Sunday should generally be the warmest, when onshore flow is the weakest of the next few days and the low clouds and fog should be the shallowest. There may even be some dense fog with low visibility, especially on the Central Coast. Gusty onshore winds will impact the interior valleys and deserts each afternoon and evening, especially Monday and Tuesday, but should stay under advisory and in the envelope of what is typical for this time of the year.

LONG TERM (WED-SAT). 08/152 PM.

Warming trend looking more likely starting Wednesday or Thursday and lasting through at least Saturday, as the previously mentioned high over northern Mexico steadily expands and strengthens each day, while shifting northward into the four corners. Projections still differ as to how much warming we can expect however. The ECMWF and most of it ensembles remain very bullish, with the core of the high expanding into southern California and onshore gradients turning slightly offshore each morning. The GFS and nearly all of its ensembles keep the core from expanding out of Arizona, with similar but weaker trends in the surface pressure pattern. While confidence is growing for widespread above normal temperature and a shrinking marine layer, to what degree is still very much an unanswered question. Prefer to lean toward the more bullish ECMWF as it seems that the GFS is trending toward it as opposed to the other way around. By leaning the forecast in that way, starting to see more daytime temperatures around 100 degrees in the warmer valleys and mountains by Friday and Saturday. At this point, not expecting an Heat Advisories, but there is a small chance in the event that the ECMWF solution wins out. No appreciable threat of any monsoonal surge through next week, but there is a window for the following week, as well as a chance for even more warming.

AVIATION. 09/0605Z.

At 0530 at KLAX . The marine layer was 800 feet deep. The top of the inversion was around 2300 feet with a temperature of 21 C.

Moderate confidence in coastal TAFs KSBA and south with a 30 percent chc of LIFR cigs 12Z-16Z. Moderate confidence in KSMX and KSBP TAFs flight cat changes could be off by 90 minutes.

Good confidence in inland TAFs.

KLAX . Moderate confidence in TAF with a 30 percent chc of 2SM BR OVC004 11Z-16z. Good confidence in TAF 17Z-06Z then low confidence with an increasing chc of LIFR conds after 06Z. There will not be any east winds greater than 6 kts.

KBUR . Good confidence in CAVU TAF. There is a 20 percent chc of 5SM HZ 13Z-16Z.

MARINE. 08/1259 PM.

High confidence that winds and seas will remain below Small Craft Advisory levels through Tuesday night across all waters. However, there is a 30% chance of SCA level gusts over portions of the coastal waters Wednesday and Thursday.

LOX WATCHES/WARNINGS/ADVISORIES. CA . NONE. PZ . NONE.

.HAZARD POTENTIAL OUTLOOK (TUE-SAT).

No significant hazards expected.
