Area Forecast Discussion National Weather Service Los Angeles/Oxnard CA 831 PM PDT Fri May 31 2024

SYNOPSIS
31/817 PM.

A cooler than normal weather pattern will continue across much of the area through the weekend as a persistent marine layer remains in place with strong onshore flow. A warming trend is expected next week, especially for the interior portions of the area Wednesday and Thursday as onshore flow weakens.

.SHORT TERM (FRI-MON)...31/829 PM.

Another warm day across the interior, with some of the warmest locations (including Antelope Valley and Paso Robles) climbing into the lower to mid 90s. A weak upper level trough across the region combined with a strong onshore flow pattern near the surface will bring a deepening marine layer trend. As of 8 pm, satellite imagery showing a rapid surge of low clouds into coastal and coastal valley locations. Current ACARS data showing the marine layer depth around 2000 feet this evening across the LA Basin so we will likely see low clouds spreading into some of the interior valleys overnight. This will also lead to a few degrees of cooling for most areas on Saturday/Sunday. The LAX-DAG gradient peaked at around +9 mb this afternoon, with similar gradients expected through Monday. Onshore wind gusts between 25 and 35 mph have been common this afternoon/evening across the interior, with local gusts to 45 mph in the Antelope Valley foothills. Similar onshore wind gusts are expected through the weekend.

*** From previous discussion ***

A few degrees of warming and slightly earlier marine layer clearing are likely Sunday and Monday as the trough starts to shift east and high pressure begins to assert itself over the west. Still below normal temperatures for coast/valleys but not as much so.

.LONG TERM (TUE-FRI)...31/230 PM.

High pressure will be building over the western states starting Tuesday and lasting through Wednesday and possibly Thursday before another trough of low pressure returns for later next week into next weekend. The warmup will be brief, and mostly confined to the interior areas, but will likely result in our first 100 degrees readings in quite some time. Based on all the ensemble runs from the NAEFS and EPS there is a greater than 80% chance of 100 degree or higher temperatures in the Antelope Valley on Wednesday with lower chances Tuesday and Thursday. Similar chances for far interior SLO County.

Closer to the coast it's a much different story. Though warming is expected for all areas, the amount of warming will be much more moderate, and for coastal areas high will likely only top out in the lower 70s at most with some beaches staying cloudy much of the day. Onshore flow is expected to weaken and be at its lowest point Tuesday and Wednesday but SST's are still only around 60 which will keep temps from warming up too much. Ensembles still indicating around 60% chance of low 90s in the warmer valley areas like Woodland Hills Wednesday, but likely in the mid to high 80s otherwise.

Troughing returns later next week into next weekend for a likely return of June gloom conditions and well below normal temperatures for coast and valleys.

AVIATION
31/2323Z.

At 2230Z at KLAX, the marine layer was 1500 ft deep. The top of the inversion was at 5200 feet with a temperature of 21 deg C.

For the 00Z TAF package, high confidence in deserts TAFs as well as KPRB. For other TAF sites (coastal and coastal valley), moderate confidence in TAFs. High confidence in return of CIG and VSBY restrictions for coastal and coastal valley sites, but low to moderate confidence in timing of flight category changes.

KLAX...Moderate confidence in 00Z TAF. High confidence in CIG/VSBY restrictions, but moderate confidence in timing of flight category changes (could be +/- 2 hours of current forecasts). No significant easterly wind component is expected.

KBUR...Moderate confidence in 00Z TAF. High confidence in return of CIG/VSBY restrictions, but moderate confidence in timing of flight category changes (could be +/- 2 hours of current forecasts).

MARINE
31/815 PM.

In the northern outer waters zone (PZZ670), SCA winds are expected to continue through at least Sunday night. Elsewhere in the outer waters, winds and seas are expected to remain below SCA levels thru Saturday morning. SCA level winds are likely (70% chance) in zones 673/676 by starting Saturday afternoon and continue through at least Sunday night. SCA conds are likely (70% chance) in all the outer waters Mon and Monday night before gradually subsiding Tuesday. Conds will likely be below SCA levels for Wed.

In the inner waters N of Pt. Sal, there is a 30% chance of SCA level winds Saturday afternoon. SCA conds are likely (60-70% chance) during the afternoon/eve hours Sun through Mon. Conds should then be generally below SCA levels Tuesday and Wednesday.

In the inner waters S of Pt. Sal, there is a 40% chance of SCA winds in western portion of the SBA Channel during the afternoon and evening hours Saturday through Sunday. Otherwise, conds over the inner waters should be below SCA levels through Wednesday.
