Area Forecast Discussion National Weather Service Los Angeles/Oxnard CA 822 PM PDT Fri Apr 26 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 (FRI-MON)...26/326 PM.

The latest satellite imagery indicate an inside-slider type trough of low pressure moving through the region this afternoon. The trough center, currently located over the California-Nevada border, will continue to push southeast into Arizona through tonight. The main story will be the winds with this system, but shower activity cannot be ruled out across the northern portion of the area, along the northern slopes, and into the San Gabriel mountains and the San Gabriel Valley tonight. There is a non-zero chance of thunderstorms across eastern Los Angeles County, but it seems highly unlikely as the best instability sits east of the area. Gusty west to northwest winds will continue to increase through this evening with the strongest winds expected across the Channel Islands, through the Interstate 5 Corridor, and into the adjacent foothills of the Antelope Valley. Winds are a little slower to develop than anticipated across much of the area, except for the Channel Islands, but multi-model ensembles suggest the winds strengthening late this afternoon. A tightening northerly pressure gradient across the region this afternoon will continue to tighten this evening, then start to relax overnight tonight into Saturday. No changes are planned to the wind headlines at this time.

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 (TUE-FRI)...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
27/0321Z.

At 2357Z at KLAX, the marine inversion was 1300 ft deep. The top of the inversion is at 1800 ft with a temperature of 16 C.

Marine layer clouds are reforming over portions of SLO/SBA Counties, generally MVFR cigs expected with a 20% chance of brief IFR conditions. Also, clouds are possible north facing slopes and in interior SLO/SBA Counties, where IFR to VLIFR conds are possible. Widespread gusty NW winds will affect the mtns and much of SLO/SBA Counties, with gusty W-NW winds in coastal and some valley sections of L.A./VTU Counties and the Antelope Valley.
Speeds may be of by 5 kts during peak winds. There is the potential for LLWS and turbulence, with mdt UDDF, until 15Z Sat.

KLAX...Moderate to high confidence in TAF until 09Z Sat, followed by lower confidence due to uncertainty in wind direction. There is the potential for LLWS and turbulence, with mdt UDDF, until 15Z Sat. There is a 30% chance of northerly cross winds of 15 kt from 09Z-14Z Sat, followed by a 20% chance of the east wind component reaching 8 kts from 14Z-18Z Sat.

KBUR...Moderate to high confidence in TAF for cigs and vis, but low confidence in winds. Wind direction will be highly variable until 10Z Sat.

MARINE
26/324 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 afternoon 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 a 40-60% chance 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/approaching gale force, and will continue through late tonight, and then drop to SCA level. 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/approaching 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.
