Area Forecast Discussion...UPDATED National Weather Service Los Angeles/Oxnard CA 1128 PM PDT Sat Apr 20 2024

SYNOPSIS
20/145 PM.

Low clouds and fog will be present on the coastal side of the mountains through at least the middle of next week, least expansive on Sunday. Sunday will be the warmest with temperatures 5 to 15 degrees above normal, with steady cooling to follow.
Drizzle is expected Tuesday through Thursday with a chance for light rain around Friday.

.SHORT TERM (SAT-TUE)...20/933 PM.

***UPDATE***

Low cloud pattern largely behaving as expected this evening with some tweaks to match the latest trends. There is a surge of low clouds that may (30-50 percent chance) reach portions of the Central Coast by sunrise. Slow to no clearing is possible again Sunday for some coastal areas south of Point Conception. Adjusted Sunday highs downward for some coastal areas, especially south of Point Conception with the entrenched marine layer pattern in place. Some breezy but sub- advisory northerly winds will continue above and inland of the marine layer with a focus along interior mountains.

***From Previous Discussion***

Low clouds are slow to burn off from Santa Barbara to Oxnard this afternoon, and look poised to be around for most if not the rest of the afternoon, and push into Los Angeles County quickly by Sundown. The expected clearing trend over the Central Coast materialized, but the wisps of clouds left in its wake bring little confidence on what will happen overnight. Could see it stay clear with the added bonus of light offshore flow forming overnight, but could also see low clouds forming as it cools down this evening.

A ridge of high pressure will quickly form overhead on Sunday, while onshore pressure gradients weaken. This should result in less marine layer coverage and noticeable warming away from the coast. Highs in the 80s will be common, with a 90 or two in the range of outcomes. The Central Coast could also see warming well into the 70s and maybe lower 80s if they stay clear. All coastal areas however will be at the mercy of the often unpredictable ebbs and flows of the marine layer.

As quickly as the ridge forms, it will be replaced by lower pressure aloft Monday and Tuesday with strengthening onshore flow.
As a result, the marine layer should expand and deepen each day.
Drizzle is possible, especially on Tuesday when most projections show low clouds pushing deep into the coastal slopes. Temperatures will lower everywhere as a result.

Northwest to northeast wind gusts of 20 to 30 mph will form over the mountains and deserts this evening, then turn onshore by Monday and Tuesday.

.LONG TERM (WED-SAT)...20/222 PM.

Most computer projections (EPS, GEFS, CMC) show a low pressure system forming over the western United States for the back half of next week. There is a wide range of outcomes however in terms of path and timing. The outcome will likely fall between two potential scenarios of 1) an inside slider (system tracks over Eastern California) which would bring no rain and some gusty north winds, and 2) a system riding the coastline which would bring some light rain and winds delayed into the follow week. There are enough solutions (20-30%) that show some rain, and considering the presence of a lot of low-level moisture from the marine layer leading up, a slight chance of rain seems warranted. The NBM blend of models continue to project chances of rain under 10%, but that is likely a consequence of model post-processing artificially lowering those chances based on the mostly dry last couple of weeks. Despite the uncertainty, fairly confident that temperatures will be well below normal for the end of next week with the cooler air mass around. One thing that this low should do in either scenario is dissolve the marine inversion which could actually result in more sunshine than what we have seen over the last few days, despite the chance of rain. As a result, the cooling will likely be mostly felt away from the coast.

AVIATION
21/0631Z.

Around 0530Z, the marine layer depth was around 1100 feet deep at KLAX. The top of the marine inversion was near 4100 feet with a temperature around 19 degrees Celsius.

Moderate-to-high confidence in the current forecast. Less confidence for coastal terminals north of Point Conception and valley terminals south of Point Conception. IFR to MVFR conditions will continue to spread back into coastal and valley terminals south of Point Conception. There is a low-to-moderate chance of LIFR conditions for coastal terminals north of Point Conception and valley terminals south of Point Conception between 10Z and 16Z. There is a moderate to high chance of no clearing at coastal terminals south of Point Conception on Sunday afternoon. An early return of IFR to MVFR conditions is expected for coastal terminals on Sunday evening.

KLAX...MVFR conditions will spread back into KLAX between 08Z and 11Z. MVFR conditions will persist through at least 17Z, or as late as 21Z. There is a 30 percent chance of MVFR conditions lingering through the day. IFR to MVFR conditions will spread back into KLAX between 01Z and 04Z. No wind impacts are expected at this time.

KBUR...IFR conditions will spread into KBUR between 11Z and 13Z.
There is a 20 percent chance of LIFR conditions between 13Z and 16Z. VFR conditions should develop around 17Z. No wind impacts are expected at this time.

MARINE
20/837 PM.

For the Outer Waters, high confidence in current forecast. Through Sunday night, Small Craft Advisory (SCA) level winds and choppy seas are expected, generally north of San Nicolas Island with the most widespread winds across PZZ670/673. For Monday through Wednesday, winds and seas will remain below SCA levels, then there is a 40%-50% chance of SCA wind gusts at times for Thursday.

For the Inner Waters north of Point Sal, high confidence in current forecast. SCA level winds are expected in the afternoon and evening hours through Sunday. For Monday through Thursday, winds and seas will remain below SCA levels.

For the Inner Waters south of Point Conception, moderate to high confidence in current forecast. For most of the southern waters, high confidence in winds and seas remaining below SCA levels through Thursday. The only exception will be the western half of the Santa Barbara Channel where there is a 50-60% chance of SCA level winds Monday night and a 40%-50% chance of these winds again on Thursday.
