Area Forecast Discussion National Weather Service Los Angeles/Oxnard CA 449 AM PST Fri Dec 13 2019
SYNOPSIS. 13/341 AM.
Today will be partly cloudy with above normal temperatures. Low pressure will bring cooler weather this weekend. There will be a chance of light rain or snow in the mountains Saturday into early Sunday. Dry and warmer weather is expected Monday and Tuesday, then there is a chance of light rain by mid week. Areas of gusty north winds are expected tonight through Sunday, then weak to moderate Santa Ana winds are possible Monday through Tuesday.
SHORT TERM (TDY-SUN). 13/408 AM.
Low clouds were widespread on the Central Coast, in the Santa Ynez and the valleys of SLO County. Another area of low clouds has pushed into coastal sections of southern Los Angeles County. Dense fog was fairly widespread in all of these areas, so a Dense Fog Advisory is in effect through mid morning for the Central Coast, Santa Ynez Valley, Salinas Valley and the L.A. County Coast. Expect low clouds to clear by mid morning, then skies should generally be mostly sunny, with less in the way of high clouds than in recent days.
Profiler data was showing some warming above the shallow 500 foot marine layer, and gradients are starting out a bit more offshore than they were on Thu. In addition, there will be more sunshine due to the lack of high clouds. However, pressure gradients are forecast to turn more strongly onshore this afternoon, and 950 mb temps will be slightly lower as will heights and thicknesses. These factors should offset each other, so expect max temps to be similar to those on Thu in most areas.
N-S gradients will be strong enough for gusts winds again tonight across southern SBA County and through the Interstate 5 Corridor, but winds should remain below advisory levels.
An upper low will approach the Oregon Coast tonight. Models show the tail end of a weakening frontal system moving into SLO and northern SBA Counties, and latest models show this front holding together enough to possibly bring some light rain to SLO and possibly northern SBA County tonight. Elsewhere, skies will become partly cloudy tonight.
As the trough drops through Oregon and northern CA and into the Great Basin Sat and Sat night, moist northerly flow will develop, bringing a chance of showers to interior sections of SLO and SBA County and the northern mountains of VTU County Sat, expanding into the mountains of L.A. County Sat night. Showers will linger on northern slopes of the mtns of VTU and northwestern L.A. County Sunday morning. Snow levels will lower quickly Sat night, possibly down to 4000 feet by early Sunday. While precipitation totals in the mountains are not expected to be excessive, snow could cause some travel problems on portions of Interstate 5 late Sat night/Sun morning.
Elsewhere, expect skies to be partly to mostly cloudy Sat, and there will be significant cooling. Gusty west to northwest winds will develop in the Antelope Valley on Sat, with gusty northwest to north winds through the Interstate 5 Corridor Sat and across southern SBA County Sat night.
Skies will become mostly sunny across the region on Sunday. However, there will likely be a bit more cooling in most areas on Sunday. Expect gusty NW-N winds to continue across the Interstate 5 Corridor on Sunday, and to develop again across southern SBA County Sun evening.
LONG TERM (MON-THU). 13/434 AM.
An upper ridge will amplify just off the West Coast on Mon, then it will move into CA on Tue. Both the GFS and the EC show offshore flow both days, stronger on Tue, with the EC the stronger of the two. As mentioned, there is not much in the way of upper level support, but expect areas of gusty northeast winds across L.A. and VTU Counties mtns, valleys and coastal areas that typically receive Santa Ana winds. The atmosphere will be rather cool, so although max temps will definitely be higher Mon and Tue than over the weekend, it will not be a warm Santa Ana, with the highest temps probably having a tough time reaching 70 degrees.
Beyond Tue, forecast confidence is very low. The GFS continues to be more progressive, with the ridge axis moving into the Great Basin Tue evening, and an upper low approaching the coast of Central CA late Tue night. This low will move across northern CA Wed, while the EC keeps it well off the coast through Wed afternoon, then brings it to near Pt Conception late Wed night, and shows it tracking to the south of the region on Thu. The operational run of the GFS brings rain to northern areas late Tue night, pushing across the entire area on Wed, turning to showers Wed night, then dry weather on Thu. The EC keeps precip off the coast trough Wed night, then takes most of the rain to the south and west of the forecast area. For now, have kept slight chance of chance pops across northern sections late Tue night, and across across the entire region Wed, following the GFS and most of its ensembles.
AVIATION. 13/1248Z.
At 0925Z, the marine layer was around 1300 ft deep. The top of the inversion was 2600 feet with a temperature of 20 degrees Celsius.
For TAF sites south of Point Conception, Low confidence with coastal TAF sites of L.A. County including KLAX, KLGB. CIGs will vary of LIFR/IFR through at least 18z. Otherwise moderate confidence after that.
For TAF sites north of Point Conception, moderate confidence in 12Z TAFs. VLIFR/LIFR conditions will continue through this morning. However, confidence in timing of flight category changes is low. Higher confidence with 12z TAFs after 18z this morning.
KLAX . Low confidence thru 18z in 12Z TAF with LIFR/IFR CIGs through 18z. Then higher confidence with VFR Conds through late this evening. There is a 50% chance for MVFR CIGs after 11z Sat morning.
KBUR . High confidence in 12Z TAF as VFR conditions are anticipated through the TAF period.
MARINE. 13/424 AM.
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 WATCH has been upgraded to a GALE WARNING for Sat afternoon and Sat 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.
For the Inner Waters north of Point Sal, moderate to high confidence in current forecast. There is a 60%-70% chance of SCA level winds Sat thru Sun night. With the gusty winds, short- period, choppy seas will be likely. High seas over 10 feet will develop this evening causing a Small Craft Advisory to go into effect for hazardous seas which, along with the gusty winds, will remain in effect through late Sun night.
For the Inner Waters south of Point Conception, moderate to high confidence in current forecast. There is a 60% chance of SCA level winds across the western half of the Santa Barbara Channel starting by mid afternoon then spread across much of the channel with northwest to west winds. Also, a few hours later, there is a 60% chance for SCA level winds for the western portion of PZZ655. the SCA level winds will continue through noon Saturday, when a GALE WARNING will go into effect for the entire inner waters for gusts to 35 knots. This will continue through late Saturday night. , The winds will shift to the north on Mon then to the east on Tue, with a 30%-40% chance of SCA level winds at times.
A large and long period west to northwest swell will impact the coastal waters through at least late Sun 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. 13/433 AM.
A large long-period west to northwest swell will continue across the coastal waters of southwest California, peaking today into 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 today and Saturday, minor coastal flooding is possible during the late morning high tides. 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 . Dense Fog Advisory in effect until 9 AM PST this morning for zones 34>37-41. (See LAXNPWLOX). High Surf Advisory in effect until noon PST Monday for zones 34-35.
