Area Forecast Discussion...UPDATED National Weather Service Los Angeles/Oxnard CA 1133 AM PDT Wed May 8 2024

Updated aviation section

SYNOPSIS
08/1004 AM.

Gusty northeast winds will continue across portions of Los Angeles and Ventura Counties this morning and some warming is expected today. Otherwise, a quiet weather pattern is expected through early next week, with dry conditions. Night through morning low clouds should become more extensive late in the weekend and early next week. Mostly minor day to day changes in temperatures are expected through Sunday, with some cooling possible Monday and Tuesday.

.SHORT TERM (TDY-FRI)...08/1011 AM.

***UPDATE***

Offshore gradients ended up being somewhat weaker than expected and a 2000' marine layer along with an eddy circulation helped spread low clouds into some of the LA coast and valley areas this morning. Despite this, temperatures should still warm up slightly over yesterday. Otherwise, a quiet weather pattern today and through most of the week.

***From Previous Discussion***

The high resolution models have really keyed in on a good eddy circulation tonight, with rather strong SE flow spreading thru the Santa Barbara Channel tonight. By Thu morning, this will evolve into a full blown southerly surge as southerly winds at the surface round Pt. Conception and spread northward into and off the Central Coast. Expect more widespread low clouds/fog in coastal areas and in the the lower valleys tonight/Thu morning. The question is whether or not the eddy circulation tonight shifts westward too much, and actually pulls clouds off the coast of L.A.
County. But in general, clouds should be more widespread tonight/Thu morning, with clearing expected in most areas by late Thu morning. There will be a fair amount of cooling at 950 mb due to the southeasterly flow, so expect several degrees of cooling in most areas west of the mountains. The exception may be across the Santa Ynez Valley and southern portions of the Central Coast, where southerly flow will downslope, producing some warming.

The upper low will drift southwestward into southern Nevada Thu night/Fri, but it will weaken, and heights will actually rise across the area. Expect night thru morning low clouds in coastal and some valley areas Thu night/Fri morning. Max temps should be up a few degrees in most areas Fri, at least away from the coast.

.LONG TERM (SAT-TUE)...08/431 AM.

The operational runs of both the GFS and the EC show the upper low reversing course and shifting eastward Fri night and Sat, with an amplifying ridge moving into the West Coast. At the surface, low level N-S gradients will increase across SLO and SBA Counties, possibly resulting in some gusty winds across southern SBA County during the evening hours Fri and Sat. Low clouds may be a bit less widespread Fri night/Sat due to the northerly flow. Also, the marine layer may become shallow enough for clouds to be confined to coastal areas. Max temps may edge upward slightly Sat. The upper ridge will flatten Sun, but heights will change little, so do not expect major changes, with night thru morning low clouds in coastal areas and locally in the valley Sat night/Sun. Max temps may come down a tad Sun as onshore flow increases slightly.

A weak upper low will move across the eastern Pacific Mon and over the region Tue. With lowering heights and increasing onshore flow, expect some cooling Mon and Tue, with more extensive night thru morning low clouds and fog extending farther inland.

AVIATION
08/1831Z.

At 16Z, the marine layer depth was around 2100 feet deep at KLAX.
The top of the inversion was near 4600 feet with a temperature near 14 degrees Celsius.

Moderate-to-high confidence in the current forecast. Higher confidence in flight categories for Los Angeles County terminals.
Less confidence in flight categories for terminals for north of KNTD. Timing could be off by up to 3 hours. VFR conditions will develop through 18Z. MVFR conditions will spread back into coastal and valley terminals south of Point Conception after 04Z. There is a low chance that conditions could arrive in the IFR category for Ventura County coastal terminals and KSBA for up to the first two hours after arrival. There is a moderate chance that MVFR conditions could linger longer on Thursday at coastal terminals.

KLAX...VFR conditions should persist through at least 04Z. MVFR conditions could arrive as soon as 05Z, or as late as 09Z.
Confidence higher flight categories relative to timing. There is a 30 percent chance that MVFR conditions could linger up to 4 hours longer than the forecast indicates.

KBUR...VFR conditions should persist through at least 08Z. MVFR conditions could arrive as soon as 09Z, or as late as 13Z.
Confidence higher flight categories relative to timing. There is a 30 percent chance that MVFR conditions could linger up to 2 hours longer than the forecast indicates.

MARINE
08/955 AM.

There is a 60-90 percent chance of Small Craft Advisory (SCA)
conditions through at least this evening for the waters northwest through southwest of the Channel Islands and along the Central Coast. SCA conditions may linger longer into tonight across the outer waters. Then, winds and seas will drop below SCA levels through at least Saturday. There is a moderate chance of SCA level winds developing late Saturday through Sunday, increasing to a high chance of Sunday afternoon and night.
