Area Forecast Discussion National Weather Service Los Angeles/Oxnard CA 422 PM PDT Sat May 25 2024

SYNOPSIS
25/200 PM.

The May gray pattern will continue through next Saturday. Varying amounts of night and morning low clouds and fog are expected for the coast and valleys during the period. Otherwise mostly clear skies will prevail. Temperatures are forecast to be a few degrees below normal into early next week then warm to near normal to a few degrees above normal for mid to late next week.

.SHORT TERM (TDY-TUE)...25/153 PM.

Marine layer clouds from this morning mostly cleared SLO/SBA Counties except for the eastern Santa Ynez Mtns and adjacent coast early this afternoon, while the low clouds over the VTU/L.A. County coast, vlys and coastal slopes changed to broken stratocu especially away from the coast. The stratocu over these areas will probably persist thru mid afternoon but should scatter out before sunset this evening. Otherwise and elsewhere, mostly sunny skies should prevail for the rest of the day.

Gusty NW winds will persist over SW SBA County thru this afternoon, with gusty W-NW winds for the Antelope Vly into the foothills and I- 5 Corridor. Winds are expected to be mostly sub- Advisory thru this afternoon. Elsewhere, breezy to gusty SW-NW winds can be expected thru this afternoon.

Temps this afternoon should be slightly warmer than yesterday but remain significantly below normal by as much as 6-12 degrees.
Highs should reach the upper 60s to low 70s for the inland coast, vlys and lower mtns.

A broad NW flow aloft with H5 heights increasing to about 576-577 dam this afternoon will turn more WSW thru Sun with H5 heights rising to 579-580 dam by Sun afternoon. Little change can be expected thru Mon night then flat upper ridging should move in with H5 heights expected to be around 584 dam by Tue afternoon.

The marine layer May gray pattern will continue thru Tue across SW CA. The marine inversion is forecast to be around 3000-3500 ft tonight then slowly lower to around 1500 ft Sun night and to about 1200-1400 ft or so Mon night. Low clouds and some fog should affect much of the coast and adjacent vlys tonight into Sun morning and up to some of the lower cstl slopes. Night and morning low clouds and fog should persist Mon thru Tue as well, with the low clouds not having as much inland penetration as the marine inversion lowers. The low clouds should clear to or off the coast for the most part each afternoon, with Santa Catalina Island probably having some low clouds linger thru much of the day.

Sundowner winds at mostly sub-Advisory levels should affect the western portions of the S SBA County coast and mtns each evening thru Tue. Otherwise, strong onshore gradients will bring breezy to gusty onshore flow to many areas, strongest afternoon and evening hours. Winds could approach Advisory levels at times in the Antelope Vly and foothills.

Temps will have a warming trend Sun and Mon then should change little for Tue. Even so, it should remain several degrees below normal during the period, except increasing to a few degrees above normal for the interior areas including some of the mtns and into the Antelope Vly for Mon and Tue. Highs for much of the inland coast, vlys and lower mtns should be in the upper 60s and 70s Sun, and in the 70s to lower 80s Mon and Tue. The warmest areas should be in the Antelope vly, with highs in the upper 80s to around 90 by Mon.

.LONG TERM (WED-SAT)...25/155 PM.

Not a whole lot of change can be expected in the extended period.
It looks like very weak upper troffiness with H5 heights around 584 dam will prevail Wed and Thu, then slightly stronger upper level troffiness will persist Fri and Sat with H5 heights around 581-582 dam.

Good onshore pressure gradients to the N and E will help to keep the marine layer pattern over the forecast area Wed thru Sat.
Varying amounts of night and morning low clouds and fog are expected for the coast and vlys, moving farthest inland Fri and Sat as the marine inversion deepens. Otherwise, mostly clear skies can be expected.

Just subtle changes in temps can be expected each day, with reading expected to be a few degrees below normal for the coast and some vlys and a few degrees above normal elsewhere over inland areas. Afternoon highs for the inland coast, vlys and lower mtns should be in the 70s to mid 80s, while the Antelope Vly heats up into the upper 80s to lower 90s each day.

Seasonably breezy onshore to northwest winds will likely continue each afternoon to evening with interior areas prone to west to northwest winds as well as southwest Santa Barbara County potentially reaching close to Advisory levels at times.

AVIATION
25/2321Z.

At 2215Z at KLAX, the marine layer was 3100 ft deep. The top of the inversion was at 6600 feet with a temperature of 12 C.

For 00Z TAF package, high confidence in desert TAFs and low to moderate confidence in coastal/valley TAFs. Lower confidence for coastal/valley sites due to uncertainties in the behavior of the marine layer stratus. Timing of flight category changes could be off by +/- 4 hours and CIGs will range from IFR/MVFR levels north of Point Conception and MVFR levels south of Point Conception.

KLAX...Low to moderate confidence in 00Z TAF. Timing of return of MVFR CIGs could be +/- 4 hours of current 06Z forecast. Timing of dissipation of MVFR could be +/- 2 hours of current 18Z forecast.
No significant easterly wind component is expected.

KBUR...Low to moderate confidence in 00Z TAF. Timing of return of MVFR CIGs could be +/- 3 hours of current 09Z forecast. Timing of dissipation of MVFR could be +/- 2 hours of current 18Z forecast.

MARINE
25/206 PM.

Moderate to high confidence in forecast.
