Area Forecast Discussion National Weather Service Los Angeles/Oxnard CA 401 PM PST Fri Jan 24 2020

SYNOPSIS. 24/1244 PM.

High pressure will keep the area dry through Saturday, with above normal temperatures expected. A very weak cold front will bring clouds and a slight chance of rain for northern areas Sunday, along with some cooler temperatures. Dry and breezy conditions are expected Monday through Thursday.

SHORT TERM (TDY-MON). 24/131 PM.

Another fine winter day across southern California with highs 5-10 degrees above normal in many areas under sunny skies except for some wispy high clouds. Winds are really the only impactful weather concern over the next few days. A moderate northerly flow has developed today that has created advisory level winds in parts of srn SB County and locally breezy north to northeast winds elsewhere. Some patchy dense fog is possible again tonight across interior SLO County and also extreme southern LA County and adjacent coastal waters.

A weak trough passing north of the area Saturday into early Sunday will briefly turn gradients onshore leading to less wind in most areas but cooler temps by a few degrees, especially on Sunday as the marine layer rapidly spins up south of Pt Conception.

However, by Sunday afternoon and night after the trough passes northerly winds will be on the increase again, likely stronger than tonight with advisory level winds in srn SB County and the I5 corridor and at least near advisory level winds in the Antelope Valley. The trough itself should be dry for most areas but the northerly flow behind it combined with lingering moisture in the Central Valley could spawn a few light showers late Sunday.

As the flow turns northeast Monday downslope flow along with a building ridge aloft will bring warmer temps back to the area once again with highs bouncing back up 3-6 degrees from Sunday's levels.

LONG TERM (TUE-FRI). 24/150 PM.

The ridge will keep the storm track well to the north and east through the week and likely into the following week. Between that and light to moderate offshore gradients temps will remain several degrees above normal. Gusty north to northeast winds at times, likely advisory levels in srn SB County and the I5 corridor. Winds will get another boost Tuesday night into Wednesday following the passage of an inside slider through the Great Basin and into northern AZ/NM. During this time there may be some isolated warning level wind gusts through the I5 corridor and srn SB County and more widespread northerly winds into the coast/valleys of LA/Ventura Counties.

The trough passage will result in some cooling for interior areas due to the cold advection but continued downslope flow will offset the cold advection aloft for coast/valleys and keep temps pretty steady.

After the inside slider moves into nrn Mexico Thursday the models have been in excellent agreement showing an even stronger ridge developing later next week into next weekend. With offshore gradients expected to continue through the period it's looking more and more likely we'll see numerous 80+ degree temps by Saturday and possibly as early as Friday. And models are still in almost unanimous agreement that this dry pattern will persist through at least the first full week in Feb.

AVIATION. 25/0000Z.

At 2355Z at KLAX, the marine layer was around 400 ft deep. The top of the inversion was near 900 ft at 17 degrees C.

High confidence in all 00Z TAFs except for KPRB, KLAX, and KLGB. For KPRB, good confidence in IFR/LIFR conditions returning late tonight, lower confidence on timing. For KLGB and surrounding south bay areas, increasing confidence of IFR/LIFR cigs/vsbys this evening, potentially becoming VLIFR overnight. There is a 40 percent chance of IFR/LIFR conditions at KLAX between 08z-16z. There is a chance of moderate wind shear and turbulence through tonight.

KLAX . High confidence in 00Z TAF through 08Z, then moderate confidence. There is a 40% chance of LIFR to IFR conditions after 08Z. There is a 30% chance of moderate wind shear and turbulence between 03Z and 07Z.

KBUR . High confidence in 00Z TAF. There is a 40% chance of moderate wind shear and turbulence through 08Z.

MARINE. 24/202 PM.

For the Outer Waters, high confidence in the current forecast. In addition to the Small Craft Advisory (SCA) level northwest winds currently impacting all the outer waters, hazardous seas will build to at least 10 feet by this evening. A combination of SCA level winds and seas are likely to continue through the forecast period. There is a 50 percent chance of gale force winds Tuesday and Wednesday.

For the Inner Waters north of Point Sal, moderate-to-high confidence in the current forecast. There is a 40% chance that marginal SCA level winds could develop this afternoon and evening, but SCA level hazardous seas above 10 feet will be very likely by late this evening. A brief break in SCA level winds and seas could develop late Saturday night through Sunday morning, but there is a 70% chance of SCA conditions Sunday afternoon through Wednesday.

For the Inner Waters south of Point Conception, moderate-to-high confidence in the current forecast. There is a 60% chance of SCA level winds across the western portion of the Santa Barbara Channel this afternoon and evening, and a SCA has been issued. There is a 70% chance of SCA level west to northwest winds and SCA level seas Sunday afternoon through Wednesday, mainly across western portions.

BEACHES. 24/152 PM.

A large, long-period northwest swell is expected to move into the coastal waters this evening and last through at least Sunday morning. A HIGH SURF ADVISORY will be in effect for all west-facing beaches starting this evening for the Central Coast, tonight for the Ventura and LA County Coast, and Saturday morning for the Santa Barbara South Coast. There is a period on Sunday where surf may drop below High Surf criteria, but another larger northwest swell is expected to move into the waters Sunday evening and last through early next week. Therefore there is a 40% chance that the High Surf Advisory may need to be extended through Tuesday.

LOX WATCHES/WARNINGS/ADVISORIES. CA . High Surf Advisory in effect until 3 AM PST Sunday for zones 34-35. (See LAXCFWLOX). Wind Advisory in effect until 3 AM PST Saturday for zones 39-52. (See LAXNPWLOX). High Surf Advisory in effect from 6 AM Saturday to noon PST Sunday for zone 39. (See LAXCFWLOX). High Surf Advisory in effect from 10 PM this evening to noon PST Sunday for zones 40-41-87. (See LAXCFWLOX). PZ . Small Craft Advisory in effect until 9 PM PST Saturday for zone 645. (See LAXMWWLOX). Small Craft Advisory in effect until 3 AM PST Saturday for zone 650. (See LAXMWWLOX). Small Craft Advisory in effect until 3 AM PST Monday for zones 670-673-676. (See LAXMWWLOX).

.HAZARD POTENTIAL OUTLOOK (MON-FRI).

Gusty northerly winds are expected through at least Wednesday, especially through the Santa Ynez Range and the Interstate 5 Corridor.
