Area Forecast Discussion National Weather Service Los Angeles/Oxnard CA 958 AM PDT Sat Jun 1 2024

SYNOPSIS
01/953 AM.

A persistent marine layer with cooler than normal weather will remain in place through the weekend as strong onshore flow continues across the area. High pressure aloft will build in next week, weaken onshore flow, and bring a warming trend to area. The hottest temperatures are expected for the interior portions of the area Tuesday through Thursday.

.SHORT TERM (TDY-MON)...01/958 AM.

***UPDATE***

Marine layer depth back up to 3500 feet this morning across the LA Basin, sloping down to around 1500 feet north of Pt Conception.
Across southern areas clouds have pushed back up the coastal slopes and all the way to Acton. Drizzle was persistent enough to create measurable rain across portions of Ventura and southern Santa Barbara Counties. Gradients are almost 3mb stronger than yesterday at this time. All this points to a very slow (if any)
clearing day across coast/valleys, especially south of Pt Conception, with temperatures 4-8 degrees below normal.

***From Previous Discussion***

A cooler than normal weather pattern is expected to persist through the weekend as strong onshore flow will remain in place.
The forecast remains near persistence along the coast while continuing a cooling trend across the interior portions of the area. Low clouds will likely struggle to clear again today, but there is a moderate chance that southern Santa Barbara County and the Ventura County coast could break out of the low clouds this evening as a northerly surface pressure gradient develops.
Statistics favor portions of the area breaking out of the clouds late this afternoon and evening, but May Gray has had its grip on the region with the month of May finishing out cooler than normal.
June is shaping up to start similarly.

Strong onshore pressure gradients will develop gusty onshore winds in the Antelope Valley and adjacent foothill areas this afternoon and evening. The latest forecast guidance puts KPMD and KWJF in the range of advisory outcomes, and a wind advisory was added from noon today to 9 pm. Certainly, the strongest winds will be expected in wind-favored locations, such as Lake Palmdale and Sierra Pelona.

A wind advisory was also added for southwestern Santa Barbara County tonight as the trough passing by will bring a tightening northerly pressure gradient. Gusty Sundowner winds will develop tonight, strongest west of Goleta out toward Gaviota and Refugio State beaches in the evening. As the northerly pressure gradient will remain in place for Sunday night and again Monday night, wind advisories may be needed again the next several nights, possibly spreading east into the southeastern portion on Monday night. EPS ensemble members continue to suggest advisory level winds developing for KSDB on Monday night and into Tuesday morning.

With the trough passing by, high pressure aloft will build into the region on Monday. A warming trend will establish and the region will start to heat up.

.LONG TERM (TUE-FRI)...01/444 AM.

The warming trend will turn more significant away from the coast across the interior portions Tuesday through Thursday. Broad troughing over the region will dig south of the border and carve out a cutoff low into the middle to late next week. An upper-level ridge will nose into southeast California. The air mass will heat up away from the coast. The latest NBM solutions suggest an 80 to 90 percent chance of KPMD and KWJF hitting the 100 degree mark by Wednesday. As well, there are low-to-moderate chances of 100 degree days on Tuesday and Thursday with chances climbing for later in the week over the previous runs. Closer to the coast, the marine layer depth will shrink some, but strong onshore flow is progged to remain in place. Thus, night through morning low clouds and fog will likely remain a staple of the forecast for the coastal and valley areas through the period. The beaches and immediate coastal areas could remain shrouded in clouds into late next week at times.

While not definite, there is an outside chance that given the southeast flow aloft, an early start to the southern California Desert Monsoon Season could begin early. EPS solutions highlight a 5-10 percent chance of precipitation at KGXA, KPMD, and KSDB and pattern recognition of the deterministic GFS solutions suggest a pattern consistent with such an outcome. For now, the forecast goes with NBM values, but there is a non-zero chance for late next week of afternoon and evening showers and thunderstorms.

AVIATION
01/1304Z.

At 12Z at KLAX, the marine layer was 2800 ft deep. The top of the inversion was at 5100 feet with a temperature of 19C.

Low clouds and fog in all coastal/valley areas, except the Cuyama Valley. Clouds have pushed into the coastal mountain slopes as well. There will be local drizzle this morning. Conds were mostly IFR to LIFR, with some VLIFR conds in the valleys/foothills and N of Pt. Conception, and MVFR conds in coastal sections of L.A./VTU Counties. Clearing will likely be slow again today, with clouds scattering out by late morning in the valleys and early afternoon across the coastal plain. Clouds will likely linger at the beaches S of Pt. Conception thru the day. Low clouds and fog will spread inland this eve, reaching the valleys (except the Cuyama Valley) and coastal slopes overnight. Conds should be mostly low MVFR to high IFR, except LIFR/VLIFR in the foothills/mtns.

KLAX...Moderate confidence in the 12Z TAF. There is a 20% chance that IFR cigs will linger until as late as 17Z. There is a 20-30% chance that cigs will scatter out between 20Z today and 02Z Sun.
There is a 20% chance that cigs will be IFR 06Z-12Z tonight.
There is a 20% chance of an east wind of 7-8 kt 09Z-16Z Sun.

KBUR...Moderate confidence in the 12Z TAF. There is a 20% chance that cigs will linger thru 20Z or 21Z. There is a 20-30% chance that cigs will arrive as early as 04Z Sun.
