Area Forecast Discussion National Weather Service Los Angeles/Oxnard CA 1208 AM PDT Sat Apr 27 2024

SYNOPSIS
26/159 PM.

An upper-level trough of low pressure will continue to move over the region through tonight. Any shower activity will likely be across the northern portion of the area and along the northern slopes of the mountains and into the San Gabriel Mountains and the San Gabriel Valley. A tightening pressure difference across the region will bring gusty and potentially damaging winds to the region through tonight. Otherwise, dry weather can be expected along with gradually warmer temperatures this weekend into the middle of next week.

.SHORT TERM (SAT-TUE)...26/845 PM.

***UPDATE***

Quite an active weather day. An inside slider moved down the CA/NV border and is now in AZ. The trof did bring quite a few showers to the upslope areas and a few showers even made it out of the mtns and into the vlys. Rainfall totals were under a a tenth of an inch. Snow levels were over 6500 ft and no measurable snowfall was reported.

Winds were the major talking point today. West to east pressure gradients peaked today near 8mb and this drove advisory level westerly winds into the coastal areas. The inside slider brought increasing offshore flow from the north as well as good upper level support and this brought warning level winds to the I-5 corridor and western AV with advisory levels winds across the rest of the mtns.

The westerly winds are subsiding as the W to E gradients relaxes the northerly winds will continue til a few hours past midnight until the cool air advection stops.

A forecast update will be issued after 900 pm to clean out the expired wind advisories and reduce the shower coverage.

***From Previous Discussion***

A warming and drying trend will develop through the weekend as an upper-level ridge developing off the Pacific Northwest coast will drop south into the state through Saturday night. Enough of northerly pressure gradient could remain to continue another round of gusty winds through the Interstate 5 Corridor and across southern Santa Barbara County Saturday night and into Sunday. While a weak semblance of a marine layer depth remains as a deep moist layer today, a return of low clouds and fog should take place over the weekend as onshore flow strengthens. The forecast brings in some mention of low clouds and fog as early Sunday morning along the Central Coast and into southern Los Angeles County.

.LONG TERM (WED-SAT)...26/326 PM.

A general ridge pattern looks to remain in place into early next week and keep a warming trend in the mix. Forecast ensembles do disagree on how warm it will get as there is a quite a mix of solutions into Monday and beyond. An onshore flow pattern will remain in place through at least the early portion of next week, but there could be a more-entrenched marine layer depth that develops if onshore flow strengthens in combination with a strengthening ridge aloft. If this occurs, the warming trend could be more muted along the coast.

AVIATION
27/0703Z.

At 0530Z at KLAX, there was no marine layer nor an inversion.

Good confidence in flight cat fcst at all sites. Wind speeds may be off by +/- 10kt through 16Z.

KLAX...Good confidence in TAF. There is a 20% chance of an 8 kt east wind component through 18Z.

KBUR...Good confidence in TAF.

MARINE
26/1045 PM.

In the Outer Waters, NW winds are at/approaching gale force, and will continue much of the time through late Sat night, with a brief drop in winds to Small Craft Advisory (SCA) level late tonight in the northern zone (PZZ670). There is a 50-60% chance of gales returning to the northern zone (PZZ670) Sat evening into Sat night. SCA level winds and seas are expected for all the outer waters after the gales subside, and will last through Tue.
There is another chance (50-70%) of gale force winds Sun through Tue, with the highest chances during the afternoon and evening hours.

In the Inner Waters N of Pt. Sal, NW winds are at/near gale force, and will drop to SCA level later tonight. SCA level winds/seas are expected much of the time Sun through Tue night, with a 30% chance of gales during afternoon and evening hours Sun and Mon.

In the Inner Waters S Pt Conception, widespread W winds are at/near gale force. Gales for all the nearshore waters will likely continue thru late tonight, then decrease to SCA level.
Then, SCA level wind and seas are likely to continue much of the time through late Sun night, (possibly Mon night in the western SBA Channel), with the strongest winds during the late afternoon thru late evening hours. There is a 50% chance of gales across the western portions of the SBA Channel late Sat afternoon into late Sat night, with a 20% chance elsewhere during that time.

Widespread strong to gale force winds will create dangerous sea conditions across the coastal waters thru the weekend, with short-period, steep, and choppy waves. There may be dangerous breaking waves near west-facing harbors. Mariners should remain in safe harbor until conditions improve.

BEACHES
26/311 PM.

Into Saturday morning, low level high surf is expected for west- facing beaches of Los Angeles/Ventura county and Catalina Island (4-7 feet, local sets to 8), and northwest to west- facing beaches along the Central Coast (7-10 feet). Moderate confidence in heights and surf will be choppy and rough, with a high risk of rip currents through Sunday.
