Area Forecast Discussion National Weather Service Los Angeles/Oxnard CA 850 PM PDT Sat Jun 1 2024

SYNOPSIS
01/836 PM.

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 (SAT-TUE)...01/849 PM.

Another warm day across the interior, with some of the warmest locations (including Antelope Valley) climbing to around 90 degrees. A weak upper level trough across the region combined with a strong onshore flow pattern near the surface will continue to bring a persistent marine layer presence. 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 1700 feet this evening across the LA Basin. Little changes in temperatures expected on Sunday, then gradual warming trend (especially interior areas) on Monday, becoming more pronounced on Tuesday when warmest portions of the Antelope Valley will be approaching 100 degrees.

The LAX-DAG gradient peaked at around +9 mb again 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 Sunday into Monday. The wind advisory for the Antelope Valley will expire at 9 pm, but may need to be reissued for Sunday afternoon/evening. The other area of wind concern tonight is Southwest Santa Barbara county, where a wind advisory is in effect until 3 am tonight for gusts up to 45 mph (strongest near Gaviota/Refugio).

*** From previous discussion ***

High pressure tries to build over the area Monday, however, there is one more weak trough that will pass through the West Coast, keeping temperatures on the cooler side still. By Tuesday the trough will be east of California. With weakening onshore flow and a warmer air mass in place most areas should experience a warming trend and much earlier clearing of the marine layer. The one exception will likely be the immediate coast where onshore flow and a strengthening inversion may keep low clouds lingering into the afternoon. Coastal valley highs Tuesday should be close to 90 and even farther inland in the deserts temps should be close to 100.

.LONG TERM (WED-SAT)...01/209 PM.

The warmest day of this stretch will be Wednesday in most areas as high pressure is at it's peak locally and onshore gradients are weakest. Still, due to the cold ocean SST's and likely a strong and low marine inversion, coastal areas temps will only rise to around normal for this time of year. Inland temperatures, though, will climb into the lower 90s for coast valleys and lower 100s for the deserts.

A cooling trend will begin in most areas Thursday as high pressure shifts east and onshore flow strengthens. By next Friday and especially Saturday highs will again be 2-5 degrees below normal for coast/valleys with a very likely return of a deepening marine layer that will keep skies cloudy into the afternoon.

AVIATION
01/2309Z.

At 2215Z at KLAX, the marine layer was 2600 ft deep. The top of the inversion was at 4800 feet with a temperature of 20 deg C.
