Area Forecast Discussion National Weather Service Los Angeles/Oxnard CA 746 PM PST Tue Jan 21 2020

SYNOPSIS. 21/555 PM.

There will be a possibility of light showers over northern San Luis Obispo County tonight, otherwise cloudy skies will prevail. A ridge of high pressure will build from Wednesday through Saturday, bringing dry weather and warming temperatures. A cold front will sweep through on Sunday bringing increasing clouds and a chance of rain.

SHORT TERM (TUE-FRI). 21/740 PM.

***UPDATE***

Th tail end of a weak storm crossing northern and Central California will cross San Luis County overnight, bringing a slight chance of light rain to that area. The best chance of rain will be late tonight, from around 3 AM through 9 AM, but even then only a hundredth or so will be possible. Light drizzle may be more likely, along with a chance of fog in the Salinas Valley. Stratus clouds are also expected to push over the L.A. Basin overnight, and should be high enough to preclude any issues with fog. Finally, Weak northerly gradients are producing north winds in some areas, including passes and canyons of the Santa Barbara South Coast and the Interstate 5 Corridor. So far winds are only gusting up to 25 mph, except for local westerly gusts around 30 mph near Lake Palmdale. The winds should increase some overnight, with gusts up to 35 mph in the L.A. mountains and west of Refugio on the South Coast. The northerly flow is expected to continue through Wednesday night, shifting to weak northeast flow late in the week.

***From Previous Discussion***

Overall, 12Z models in good synoptic agreement through the short-term period. At upper levels, ridge will build along the West Coast through Thursday then remain in place on Friday.

For Wednesday and Thursday, benign weather will continue across the area. Other than some night and morning clouds across interior sections of SLO/SBA counties, skies should generally be mostly clear. Northerly flow will continue through Wednesday night then will shift to the northeast on Thursday. Surface gradients are not too strong from either the north or northeast and upper level support is minimal. So, do not anticipate any widespread advisory level winds across the area. However, through Wednesday evening there may be some localized advisory-level gusts around Gaviota and Refugio. The combination of the building upper level ridge and weak offshore surface gradients, temperatures will exhibit a warming trend through Thursday. In fact on Thursday, many coastal and valley areas will be in the lower to mid 70s.

For Thursday night and Friday, a swath of mid and high level clouds will drift over the area, bringing partly to mostly cloudy skies, but no rain. With weak offshore flow continuing, temperatures will remain warm on Friday with many areas a few degrees above seasonal normals.

LONG TERM (SAT-TUE). 21/202 PM.

For the extended, models continue to exhibit good synoptic agreement. At upper levels, ridge will hang tough on Saturday, then a trough will swing through the area on Sunday with a ridge building behind the trough on Monday and Tuesday. Near the surface, weak offshore will linger on Saturday, shift to onshore on Sunday then good northerly flow on Monday and Tuesday.

For Saturday, the weather should be very unexciting. With upper level ridge still hanging on, it will still be rather warm with many coastal and valley areas still in the lower to mid 70s. Clouds ahead of an upper level trough will start to move into the area, bringing partly to mostly cloudy skies to the area, especially across SLO/SBA counties. With weak offshore gradients, there will be some local, sub-advisory level, winds.

On Sunday, the upper level trough will sweep over the area with an associated cold front. Front looks to lose steam as it round Point Conception, so best chances for any appreciable rain will be over SLO/SBA counties. Will go with chance POPs for SLO/SBA counties and slight chance POPs for Ventura/LA counties during the day on Sunday with some lingering small chances Sunday night (especially over the north-facing slopes). Rainfall totals, if any, look to be pretty light, generally under 0.25 inches. Snow levels will drop to around 7000 feet, so there may some light dusting of snow at higher elevations.

For Monday and Tuesday, dry and mostly clear conditions are expected. Will need to monitor the potential for some gusty northerly winds across the area. Both the GFS and ECMWF are forecasting decent northerly gradients (LAX-BFL, SBA-SMX and SBA- BFL) especially out to 6-7 days. Additionally, there looks to be some decent thermal and upper level winds on Monday and Tuesday. So, there is a decent chance of at least advisory-level northerly winds across the area. With the northerly flow and plenty of sunshine, temperatures will rebound a few degrees both Monday and Tuesday.

AVIATION. 22/0016Z.

At 2300Z, there was no marine inversion at KLAX.

Moderate confidence in TAFs overall, with moderate confidence in the SLO County TAF sites where there is a slight chance of -RA or DZ and lower cigs. Also moderate confidence in LA coast and valley sites with MVFR cigs/vsby are likely overnight. There is a 20% chance of reduced cigs/vsby at other coastal sites for the overnight period.

KLAX . Moderate to high confidence in the 00Z TAF. The timing of MVFR cigs may differ by 2 hrs from TAF times. There is a 20% chance the site will remain VFR overnight. East winds overnight are expected to remain under 06 knots.

KBUR . Low to moderate confidence in the 00Z TAF. There is a 30% chance the site will remain VFR through the period. Timing of MVFR cigs may differ by at least 2 hrs from TAF times, and there is a 30% chance conditions lower to IFR.

MARINE. 21/739 PM.

Hazardous seas will continue to affect the outer waters and inner waters north of Point Sal through late Wed night. There is a 50% chance that seas will remain above Small Craft Advisory (SCA) levels through much of the week. Winds are expected to remain below SCA levels through Thu, though there is a 40% chance of SCA level wind gusts across portions of the outer waters Wed afternoon and evening. SCA level NW winds are likely across the outer waters Fri thru Sunday, possibly beginning as early as late Thu night.

SCA level NW winds will be possible across the northern inner waters Fri evening and Sunday.

SCA conds are not expected thru the period across the southern inner waters or the Santa Barbara Channel, although there is a chance of SCA gusts over the western SBA Channel Sunday.

BEACHES. 21/742 PM.

A large long-period WNW swell will affect the coastal waters through Wednesday night. Surf of 10-13 feet is expected on west and northwest facing beaches of the Central Coast. The peak of the surf is likely occuring this evening with max sets to 14 feet possible. The surf will then gradually diminish late tonight through Wednesday. A High Surf Advisory is in effect for the Central Coast beaches through 6 PM Wednesday.

LOX WATCHES/WARNINGS/ADVISORIES. CA . High Surf Advisory in effect until 6 PM PST Wednesday for zones 34-35. (See LAXCFWLOX). PZ . Small Craft Advisory in effect until 3 AM PST Thursday for zones 645-670-673-676. (See LAXMWWLOX).

.HAZARD POTENTIAL OUTLOOK (FRI-TUE).

There is the possibility of gusty north winds on Monday and Tuesday, especially through the Santa Ynez Range and the Interstate 5 Corridor.

In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
