Area Forecast Discussion...UPDATED National Weather Service Los Angeles/Oxnard CA 838 AM PDT Fri Jun 21 2024

SYNOPSIS
21/222 AM.

Above normal temperatures are expected today into early next week, particularly for areas away from the coasts. Dangerously hot conditions are possible this weekend, especially for the mountains and Antelope Valley. There is a slight change of rain showers or thunderstorms Saturday through Tuesday.

.SHORT TERM (TDY-SUN)...21/837 AM.

***UPDATE***

The forecast is well on-track, and no changes have been made to the ongoing forecast.

***From Previous Discussion***

Today the trough overhead will weaken, giving way to high pressure creeping in from the east. This area of high pressure will overspread much of the southern United States on Saturday, with SoCal under the westernmost portion. Heights will rise rapidly today and Saturday, and then will stagnate for Sunday, when the center of the high pressure starts to settle over Arizona and New Mexico. With rising heights compressing the marine layer and decreasing onshore pressure gradients, cloud cover will be minimal today. Additionally, temperatures will increase by 4 to 10 degrees across the region compared to the previous day.

For most areas, daytime highs will peak over the weekend. Expect temperatures ranging from 102 to 108 degrees across the Antelope Valley, from 90 to 100 for the interior valleys, and in the mid 80s to mid 90s for inland coastal plains. Only the beaches will see temperatures in the 70s, with upper 60s possible along the Central Coast. Minimum temperatures will be warm Saturday and Sunday night, offering little relief from the heat, especially for inland locations. Overnight lows will be as warm as 80 degrees for portions of the Antelope Valley and some mountain areas.
Excessive Heat Watches have been issued for this weekend, that include the Antelope Valley and foothills, the San Gabriel Mountains, Ventura Mountains, Interior Santa Barbara Mountains, and the I-5 Cooridor. Heat Advisories have also been issued for the weekend, to include interior San Luis Obispo County, the Santa Clarita Valley, the San Fernando Valley, and the San Gabriel Valleys. Please see the product LAXNPWLOX for all of the details.
With little change to the pattern going forward, theses heat products may be extended into mid next week.

There is a chance of showers or thunderstorms across Los Angeles County and the southern coastal waters on Sunday. A stream of moisture from the remnants of Tropical Storm Alberto will be funneled into the region within the anticyclonic flow around the high pressure. Even if no showers develop, the additional mositure will increase humidities and slightly moderate temperatures, dampening daytime highs and raising overnight lows. This will further intensify the impacts of the high temperatures both during the day and overnight. Heat related preparations and precautions are advised for this weekend.

.LONG TERM (MON-THU)...21/308 AM.

Both the GFS and the EC as well as their respective ensembles agree that the large and warm upper high will remain over the AZ/NM region through Wednesday and then push off to the east on Thursday. Hgts will remain near 594 dam though Wed and fall a few dam on Thu.

There is good agreement that the predominate flow pattern will be from the SW on Mon and Tue. This will keep any monsoon moisture well to the east of the area. On Wednesday some ensemble members begin to hint at a more southerly or even southeasterly flow pattern with some chance of a monsoon moisture push. There is still not enough agreement to put convection into the fcst but this day will need watching. The eastward progression of the upper high Thursday will bring dry SW flow to Srn CA and eliminate any convective threat.

The combination of a strong East Pac high and strong thermal low over the CA/AZ border will produce a strong (~9mb) W to E onshore push each afternoon. This will bring near advisory level winds to the western Antelope Valley and foothills each afternoon.

The very strong marine inversion will continue through the period.
Night through morning low clouds and fog (likely dense at times)
will continue across the near shore areas through the period.
Despite the strong onshore push the low clouds will not extend too far inland since the marine will will be squashed down to ~500 ft. The combination of a very strong capping inversion and strong afternoon onshore flow will likely keep many west facing beaches cloudy all day.

Hgts fall just enough Monday to bring 2 to 4 degrees of cooling to the area. This should be enough to bring temps just below advisory criteria. After that, with hgts and gradients fairly similar through Thursday there will not be much day to day change in temperatures. Max temps will remain 8 to 10 degrees above normal across the mtns and far interior, 4 to 6 degrees above normal for the vlys and a few degrees either side of normal for the near shore areas.

AVIATION
21/1152Z.

At 1115Z at KLAX, the marine layer was 1100 feet deep. The top of the inversion was at 2300 ft with a temperature of 21 deg C.

Low confidence in the KOXR TAF with a 40 percent chc of IFR cigs through 15Z.

Moderate confidence in TAFs for KPRB, KSBP and KSMX where flight cat changes could be off by +/- 90 minutes and cigs hgts off by 300 ft.

Moderate confidence in TAFs for KSMO, KLAX and KLGB. There is a 25 percent chc of MVFR vis this morning. There is a 30 percent chc of IFR cigs after 07Z this evening.

KLAX...Moderate confidence in TAF. There is a 25 percent chc of 4SM HZ through 17Z. here is a 30 percent chc of OVC006 conds after 07Z this evening. No significant east wind component is expected.

KBUR...High confidence in TAF.

MARINE
21/233 AM.

For the Outer Waters, high confidence in current forecast. Small Craft Advisory (SCA) winds will continue through this evening.
Thereafter, SCA conditions are not expected through at least early next week.

For the Inner Waters north of Point Sal, moderate to high confidence in current forecast. SCA winds are likely this afternoon and evening after a brief lull this morning. Thereafter, SCA conditions are not expected through at least early next week.

For the inner waters south of Point Conception, moderate to high confidence in current forecast. SCA winds are not expected over most of the area, but the western third of the Santa Barbara Channel will have local gusts to 25 kts this afternoon and evening. Otherwise, SCA conditions are not expected through at least early next week.

There is a slight chc for a few thunderstorms across the southern portion of the local waters this weekend, as remnant upper-level moisture from Tropical Cyclone Alberto advances into the region.
