Area Forecast Discussion National Weather Service Los Angeles/Oxnard CA 807 PM PST Fri Dec 13 2019

SYNOPSIS. 13/741 PM.

Morning low clouds and fog will spread into the valleys this morning. There is a slight chance of very light showers today through Sunday morning. Elevated surf will persist this weekend. A moderate Santa Ana is expected Monday and Tuesday, followed by rain on Wednesday.

SHORT TERM (FRI-MON). 13/806 PM.

***UPDATE***

For the immediate short-term, everything looks on track. Latest satellite and surface observations indicate partly to mostly cloudy skies across the area. Current soundings indicate marine inversion around 1000 feet deep early this evening and some stratus is impacting the coastal plain. Overnight, expect the inversion to deepen as cold front approaches. So, low clouds should push into the coastal slopes late tonight with the possibility of some light drizzle.

With regard to the cold front, its still forecast to move across the area tonight. There will continue to be a threat of light showers across the Central Coast tonight and over the interior and northern mountain slopes late tonight through Saturday afternoon.

Other issue of note this evening is gusty northerly winds. Latest surface observations indicate northerly winds around 40 mph across southern Santa Barbara county. So, will keep WIND ADVISORY in effect for these areas through tonight. Otherwise, winds are relatively light this evening, but west to northwest winds should start to increase overnight as the cold front sweeps through.

Overall, current forecast has good handle on the situation. So, no significant updates are planned.

***From Previous Discussion***

Interesting day along the coast today where a shallow marine layer pushed onshore and lingered for much of the day near Lompoc, the Oxnard coastal plain, and parts of the LA coast. Even parts of the southern Salinas Valley stayed cloudy. The strong onshore trends were a big reason for this and temperatures definitely trended cooler for coastal areas and some of the valleys too.

A weak cold front is approaching from the north and this will further increase onshore flow and cause the marine layer to rapidly deepen later tonight into Saturday, mainly across LA/Ventura Counties. In fact, there's a good chance we'll see some drizzle or even light showers, especially along the foothills of the eastern San Gabriels. Increasing west to northwest flow will help clear skies out along the Central Coast south through Ventura County by afternoon but clouds will likely linger in LA County much of the day. Several degrees of cooling all areas Saturday as a result with highs just in the low to mid 60s for coast/valleys. Slightly warmer across srn SB County due to downslope flow there.

It will be a breezy afternoon in many areas with marginal advisory level winds. Even stronger winds expected Sat night into Sunday morning, especially srn SB County with sundowners and in the I5 corridor and Antelope Valley. Some of those winds will filter down into the coast and valleys of LA/Ventura Counties as well but probably below advisory levels.

Moist, upslope flow near the Grapevine late Saturday into Sunday morning will likely generate some showers there with the snow level lowering to 3500-4000'. Good chance we'll see some light snow at pass level and possibly even an inch or two of accumulation. May need to consider a winter weather advisory due to snow and gusty winds and the impacts to major highways like Interstate 5.

Breezy north winds expected to continue in many areas Sunday but strongest in the mountains. Otherwise mostly sunny in most areas with temps still a few degrees below normal.

By Monday we shift to a moderate Santa Ana wind event. The NAM checked in with a LAX-DAG gradient close to -6mb with better upper support than would be expected given the upper level pattern. The ECMWF has been pretty consistent showing near advisory level northeast winds across the usual favored parts of LA/Ventura Counties Monday and the NAM would certainly agree. With the ridge building in from the west we can expect at least a few degrees of warming Monday with the warmest temps along the LA/Ventura coast.

LONG TERM (TUE-FRI). 13/206 PM.

One more day of Santa Anas/offshore flow Tuesday. The EC has been consistent showing the strongest gradients Tuesday morning but would have to think that upper support would be weaker with the ridge right overhead. EC ensembles have been favoring Tuesday as the strongest day for Santa Ana winds but would not be surprised if that's reversed or at the very least similar. Either way probably a second day of low end advisory level winds in LA/Ventura Counties with similar or slightly warmer temps.

Forecast confidence drops quite a bit for mid week as models have not been in good agreement on the pattern evolution and timing of the next trough. GFS and EC are in better agreement today on the pattern but the GFS is finding a much deeper source of moisture than the EC is. So still a chance of rain Wed into Thu with best odds across SLO/SB Counties. Rainfall amounts probably under a half inch either way, and possibly much less.

Good confidence in dry and slightly warmer weather the last part of Thursday and Friday with an upper ridge returning.

AVIATION. 13/2313Z.

At 2245Z, the marine inversion at KLAX was based at 1400 feet. The top of the inversion was 3600 feet with a temperature of 18 degrees Celsius.

Overall, moderate confidence in 00Z TAF package. High confidence in CIG/VSBY restrictions at all coastal/valley sites, but low confidence in flight categories and timing of flight category changes. Most sites will have CIGs start out at IFR/LIFR levels, but will increase to MVFR levels overnight and into Saturday morning.

KLAX . Overall, moderate confidence in 00Z TAF. Timing of change from IFR to MVFR conditions could be +/- 3 hours of current 09Z forecast. Timing of dissipation of MVFR CIGs could be +/- 2 hours of current 22Z forecast. No significant easterly wind component is expected.

KBUR . Overall, moderate confidence in 00Z TAF. Timing of arrival of MVFR CIGs could be +/- 3 hours of current 10Z forecast with a 30% chance of CIGs starting at IFR levels. Timing of dissipation of MVFR CIGs could be +/- 2 hours of current 22Z forecast.

MARINE. 13/806 PM.

For the Outer Waters, moderate to high confidence in current forecast. Small Craft Advisory (SCA) level winds and/or seas will continue through at least late Sun night. The GALE WARNING is in effect for Saturday afternoon and Saturday night for PZZ676. With the gusty winds, short-period, choppy seas will be likely. High seas over 10 feet will continue through late Sun night, therefore a SMALL CRAFT ADVISORY is not only in effect for winds, but for hazardous seas. There is a 30% chance that GALE force winds could occur across the southern portion of zone PZZ673 for areas S of Point Conception during the same time as the Gale Warning in the southern zone. On Tuesday and Wednesday, there is a 50% chance of SCA level east to southeast winds.

For the Inner Waters north of Point Sal, moderate to high confidence in current forecast. SCA level winds are expected Saturday and Saturday night with short-period, choppy seas. Additionally, SCA level seas will continue through Saturday night. On Tuesday, there is a 50% chance of SCA level southeast winds.

For the Inner Waters south of Point Conception, moderate to high confidence in current forecast. For tonight through Sunday, SCA level west to northwest winds are expected with a 70% chance of Gale force winds Saturday and Saturday night (with the strongest winds across western sections). A GALE WARNING will remain in effect for Saturday and Saturday night. From Sunday night through Wednesday, the winds will shift to the northeast with SCA level winds likely Sunday night through Tuesday.

A large and long period west to northwest swell will impact the coastal waters through at least late Sunday night, resulting in hazardous sea conditions and large breaking waves near shore, especially with a large short period wind swell on top of that. Breaking waves at the Morro Bay and Ventura Harbor entrances will be possible.

BEACHES. 13/806 PM.

A large long-period west to northwest swell will continue across the coastal waters of southwest California, peaking through Saturday morning, then slowly diminish over the remainder of the weekend.

Surf will likely peak between 12 and 16 feet for the Central Coast. A HIGH SURF ADVISORY is in effect for the Central Coast through Monday morning.

A HIGH SURF ADVISORY is also in effect through noon Sunday for the beaches south of Point Conception with surf between 6 and 10 feet possible. Highest surf will occur across exposed west facing beaches. Strong rip currents and dangerous breaking waves are expected.

With high tides around 6.5 feet Saturday, minor coastal flooding is possible during the late morning high tide. Any coastal flooding impacts should be confined to the beaches, with flooding possible in the most vulnerable parking lots, bike paths, and walkways.

LOX WATCHES/WARNINGS/ADVISORIES. CA . High Surf Advisory in effect until noon PST Monday for zones 34-35. (See LAXCFWLOX). High Surf Advisory in effect until 4 AM PST Sunday for zone 39. (See LAXCFWLOX). Wind Advisory in effect until 3 AM PST Saturday for zones 39-52. (See LAXNPWLOX). High Surf Advisory in effect until noon PST Sunday for zones 40-41-87. (See LAXCFWLOX). PZ .
