Area Forecast Discussion National Weather Service Los Angeles/Oxnard CA 1037 AM PST Sun Dec 8 2019

SYNOPSIS. 08/653 AM.

Showers will continue across the region today with a slight chance of thunderstorms. Conditions will be dry for the remainder of the week with much warmer temperatures by Thursday.

SHORT TERM (TDY-TUE). 08/843 AM.

Showers continue today as a few more mini-frontal boundaries come through. Brief moderate to heavy downpours possible with rain rates up to around .50"/hr and possibly an isolated thunderstorm up north but no threats to burn areas. Snow levels currently in the 7000-8000' range but are lowering as the upper low moves into the Sac Valley but not expected to drop below 6000' so no snow on the Grapevine and only a few inches of snow expected at higher elevations.

***From previous discussion***

North flow will move into the area tonight and the showers will stop except on the north slopes where upslope flow will bring showers that will last into the night. It will be breezy across the SBA south coast and the I-5 corridor but likely under advisory criteria.

Ridging will build into the area on Monday and will persist into Tuesday. Skies will be partly cloudy at worst. There may be some patch low clouds and/or for in the mornings if the skies are clear enough to efficiently radiate. There will also be a little sub advisory NE wind event Tuesday morning. Max temps will rise 1 or 2 degrees each day and by Tuesday most max temps will be near normal.

LONG TERM (WED-SAT). 08/320 AM.

The upper level ridge will move E Tue night as an upper level trof pushes into the area. The trof is dry and there is no rain threat. It will usher in a little north wind event Wednesday morning. There will be enough mid clouds to call the day partly cloudy. Max temps will not change much from Tuesday.

On Thursday a weak ridge extends into the area from the SW and hgts rise to about 584 DM. A SFC high will build into the great basin and there will be offshore flow from both the east and north. It will not be that strong and do not expect advisory level winds probably just 15 to 25 mph in the morning. It should be a sunny day and max temps will jump 4 to 8 degrees ranging from the upper 60s to the mid 70s which is 3 to 5 degrees above normal.

The ridge flattens out a little on Friday but this should not affect the day too much. Expect the day to look much like Thursday perhaps a degree or two warmer.

The ridge begins to break down on Saturday but there will not be much consequences. Skies might be partly cloudy. Max temps will fall 2 to 4 degrees but will still be a degree or two above normal.

Both the EC and GFS hint at a weak system next Sunday but at this point it looks pretty unimpressive.

AVIATION. 08/1836Z.

At 1759Z at KLAX, there was a deep moist layer with no inversion.

Low confidence in all 12Z TAFs except moderate for desert TAF sites. Conditions early this morning will mostly range between IFR and MVFR with frequent fluctuations likely.

KLAX . Low confidence in the 18z TAF. Conditions will likely fluctuate between IFR and MVFR. Good confidence in any east wind component remaining below 5 kt.

KBUR . Low confidence in the 18z TAF. Conditions will likely fluctuate between IFR and MVFR.

MARINE. 08/1020 AM.

For the Outer Waters, moderate confidence in the forecast. Winds will turn northwest this morning and are expected to increase through the day. A SCA has been issued for the southern two zones of the outer waters for this afternoon and tonight, but with no more than moderate confidence. Moderate confidence in SCA level winds over the southern portion of the outer waters on Wednesday.

For the Inner Waters north of Point Sal, high confidence in current forecast. Winds and seas will likely remain below SCA levels through Wednesday.

For the Inner Waters south of Point Conception, moderate confidence in current forecast. Winds will turn northwest this morning and are expected to increase through the day. SCA level winds should develop across the Santa Barbara Channel and southeastward towards Catalina Island this afternoon and lasting through late tonight. Winds weaken early Monday, then conditions will likely remain below SCA level through midweek.

BEACHES. 08/1024 AM.

A relatively large, long-period, west to northwest swell will continue to bring high surf conditions to the Central Coast as well as the Ventura and Los Angeles County coast through Sunday afternoon.

For the Central Coast, surf heights will peak between 9 and 12 feet this morning, before lowering to between 7 and 10 feet. For exposed west-facing beaches of Ventura and Los Angeles counties, surf heights will be 4 to 7 feet with sets to 8 feet near the Ventura harbor as well as between Manhattan Beach to the Palos Verdes Peninsula. High surf advisories will continue for these areas through this afternoon. For the west-facing beaches of southern Santa Barbara county, there will be elevated surf conditions across exposed west facing beaches through this afternoon with surf heights of 3-5 feet.

For all coastal areas . there will be an increased risk for ocean drowning. Rip currents can pull swimmers and surfers out to sea. Large breaking waves can cause injury . wash people off beaches and rocks . and capsize small boats near shore.

Late this week there will be the potential for a larger surf episode along our west-facing beaches originating from a northern Pacific storm system. Tides will be building toward 7.0 feet by Friday which would also bring a risk of coastal flooding. Stay informed about this event if you have plans near the ocean next week.

LOX WATCHES/WARNINGS/ADVISORIES. CA . High Surf Advisory in effect until 5 PM PST this afternoon for zones 34-35-40-41. (See LAXCFWLOX). PZ . Small Craft Advisory in effect until 3 AM PST Monday for zones 650-655-673-676. (See LAXMWWLOX).

.HAZARD POTENTIAL OUTLOOK (TUE-SAT).

No significant hazards expected.

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
