Area Forecast Discussion National Weather Service Los Angeles/Oxnard CA 1002 AM PDT Sat May 4 2024

SYNOPSIS
04/922 AM.

A cold storm system will move over the region through Sunday bringing periods of light rain to the area this afternoon and evening. Temperatures will be much cooler than normal through Sunday and there will be gusty winds at times. Dry and warmer weather is expected next week.

.SHORT TERM (TDY-MON)...04/947 AM.

***UPDATE***

A weak but unusually cold storm system will move through California today into early Sunday. Really no changes in the timing and amounts from earlier predictions. Light rain has made it as far south as Monterey as of 9am and should be reaching the SLO County line by early afternoon. While northwest SLO County still stands to get around a quarter to half inch of rain with this system, due to the storm moving inland over northern California rain amounts drop off pretty fast to the south. The exception being southeastern LA County and the north facing mountain slopes where up to a third of an inch of rain is expected. In the downsloping area between southern Santa Barbara County and western LA County amounts drop off to a tenth of an inch or less. In most areas the duration of rain will be short, around 3-4 hours.

***From Previous Discussion***

Snowfall amounts will be light. While snow levels will lower down to 4000 to 4500 feet late tonight or early Sunday morning, most of the moisture will likely vacate the area by that time. At most, a dusting to an inch of snow are likely with local amounts up to two inches.

Gusty winds will start to develop across the San Gabriel Mountains, and the Antelope Valley and the adjacent foothills this afternoon and this evening as the surface pattern tightens ahead of the cold front. A wind advisory remains in effect for this afternoon and tonight for these areas. After the front passes over the region, a tight surface pressure gradient will remain into Sunday and Sunday night. There is a good chance that the advisory for the San Gabriel Mountains, and the Antelope Valley and the adjacent foothills may need to be extended into Sunday and Sunday night. Wind advisories were added for the entire coastal areas and into the Santa Ynez Valley for gusty west winds on Sunday afternoon and evening, and for the Transverse Ranges and into southern Santa Barbara County for gusty northwest winds developing late tonight through early Monday morning.

A cold air mass will spread into the area today and Sunday. There is a moderate chance that low maximum temperatures records could fall on Sunday out in the desert as the air mass will be cold for May, more inline with February or March. Temperatures in the 60s will be common across most areas the next several days, coldest on Sunday for areas south of Point Conception.

.LONG TERM (TUE-FRI)...04/529 AM.

The forecast ensemble members continue to suggest a warming and drying trend developing through Wednesday as high pressure aloft reestablishes over the eastern Pacific Ocean and a low pressure system dives through the Great Basin. There is a chance that a cool down could arrive for late week as onshore flow increases.
EPS ensembles continues to keep cloud cover means free of the marine influence, but confidence remains moderate at best due to the time of the year.

AVIATION
04/1701Z.

At 1600Z at KLAX, the marine layer was 3800 feet deep. The top of the inversion was at 5600 feet with a temperature of 13 degrees Celsius.

Overall, low to moderate confidence in 18Z TAF package. Combination of deep marine inversion with approaching weak system will bring clouds and visibilities ranging from IFR to MVFR through the period. Confidence in timing of flight category changes will be low through the period. Light showers will be possible across the area late this afternoon through tonight.

KLAX...Moderate confidence in 18Z TAF. There is a 30% chance of MVFR CIGs 18Z-04Z. For tonight, high confidence in return of MVFR CIGs , but only moderate confidence in timing (could be +/- 3 hours of current 04Z forecast). High confidence in VFR conditions after 15Z. No significant easterly wind component is expected.

KBUR...Moderate confidence in 18Z TAF. There is a 40% chance that VFR conditions will develop 18Z-03Z. For tonight, high confidence in return of MVFR CIGs , but only moderate confidence in timing (could be +/- 3 hours of current 03Z forecast).
