Area Forecast Discussion National Weather Service Los Angeles/Oxnard CA 414 PM PST Mon Dec 9 2019

SYNOPSIS. 09/903 AM.

It will be mostly sunny today with slightly below normal temperatures. Other than occasional partly to mostly cloudy skies, the conditions will be dry with mostly sunny skies. A slow warming trend will bring slightly above normal temperatures to the area by Thursday.

SHORT TERM (TDY-THU). 09/132 PM.

High amplitude ridging remains in place over the region this afternoon. Some clouds remain over the interior portions of the area this afternoon and patchy fog should return tonight. Temperatures will remain on the cool side of normal for this time of year for today and tonight as a due northerly flow pattern remains in place.

The latest GOES-West imagery shows a shortwave trough digging south near the California-Nevada border this afternoon. The weak trough will brush the area late this afternoon or early this evening bring mainly middle and high level clouds to the region. Breezy to locally windy northerly winds are possible tonight through the Interstate 5 Corridor tonight, before turning northeast and weakening late.

The ridge axis will push over the region on Tuesday morning, then clouds should increase over the region as a trough near 35N and 150W will advance toward northern California. Isolated shower activity cannot be ruled out for the Central Coast and San Luis Obispo County, but the trough is rather disorganized with the middle and upper-level instability running out ahead of the lower-level moisture. PoPs remain on the dry side, but were increased north of Point Conception. The main impact of the trough will be mostly cloudy skies and cooler conditions for Wednesday along with some breezy to locally windy conditions through the Interstate 5 Corridor and across southern Santa Barbara County.

The trough should exit the region on Wednesday night and high pressure aloft should build in through Thursday. Offshore flow will develop and temperatures should warm to above normal on Thursday. Advisory level northeast winds do not look likely for Thursday, but breezy to locally windy conditions could develop through and below passes and canyons.

LONG TERM (FRI-MON). 09/155 PM.

Warmer than normal conditions should remain into Friday, then a weak trough of low pressure will sag south for the weekend. PoPs and rain chances were tweaked a bit, but the best chance for any rainfall will be for the northern areas, including San Luis Obispo County and the northern slopes of the mountains. Advisory level winds should develop between Saturday and Sunday through the Interstate 5 Corridor and across southern Santa Barbara County.

A moderate Santa Ana could be setting up for early next week in the wake of the storm. ECMWF ensembles indicate several members with strong winds across eastern Ventura and western Los Angeles Counties. More confidence is placed more for the mountains and the Santa Clarita Valley at this time, but the coastal and valley area will have to be watched more closely. The latest GFS surface pressure gradients suggest -5.1 mb pressure gradient between KLAX and KDAG. Regardless, warmer conditions should expected for Monday and Tuesday of next week.

AVIATION. 10/0013Z.

At 2302Z at KLAX, there was no marine layer, but a weak inversion was around 6700 ft deep.

S of Point Conception . High confidence with 00z TAFs except lower at KLAX, where there is a 30% for LIFR conds and 50% at KLGB between 12z-16z Tue.

N of Point Conception . Moderate confidence with 00z TAFs. There will be some LLWS +/- 10kt possible at KSBP KSMX with NE winds aloft and NW-N winds at surface through the overnight hours. There is a 30% chance that patchy stratus will develop along portions of the Central Coast bringing LIFR Conds between 10z-16z Tue. Low confidence on KPRB, with a 50% chance for LIFR/IFR cats lasting a few hours past 17z.

KLAX . High confidence in VFR cats through at least 09Z. Then 30% chance of LIFR cats late tonight into Tuesday, with a potential start window (11-15Z). East winds likely 08-18Z Tuesday, moderate confidence of staying below 8KT.

KBUR . High confidence in VFR through Tuesday.

MARINE. 09/103 PM.

Moderate confidence Small Craft Advisory (SCA) conditions from Point Conception to San Nicolas Island through tonight. Winds will stay under SCA Tuesday through Wednesday morning, with SCA conditions possible for the same area Wednesday afternoon into Thursday. More widespread gusty NW to W winds possible Friday and Saturday with building seas.

A large and long period W to NW swell will impact the coastal waters later Thursday and continue through Saturday, resulting in hazardous sea conditions and large breaking waves near shore. Breaking waves at the Morro Bay and Ventura Harbor entrances are possible.

Patchy dense fog with low visibility possible through at least Tuesday. SE winds up to 15 kt possible Tuesday morning between islands.

BEACHES. 09/959 AM.

A large long-period west to northwest swell will push into southwest California Thursday night, peak on Friday, then slowly decay over the weekend. Swells should peak at 12 to 15 feet off the Central Coast, and 5 to 8 feet over the southern waters. High Surf Advisories look likely, with strong rip currents and dangerous breaking waves. There is a small chance for warning-level surf over 20 feet along the Central Coast. With high tides around 6.5 feet, minor coastal flooding is possible late Friday and Saturday mornings. Any coastal flooding impacts should be confined to the beaches, with flooding in the most vulnerable parking lots, bike paths, and walkways.

LOX WATCHES/WARNINGS/ADVISORIES. CA . NONE. PZ . Small Craft Advisory in effect until 3 AM PST Tuesday for zones 673-676. (See LAXMWWLOX).

.HAZARD POTENTIAL OUTLOOK (THU-MON).

High surf is likely and minor coastal flooding is possible for late this week at area beaches. Strong north winds possible Sunday in southern Santa Barbara County, and parts of LA/Ventura Counties.

It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. 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.
