Area Forecast Discussion . UPDATED National Weather Service Los Angeles/Oxnard CA 406 PM PST Fri Dec 6 2019

updated aviation discussion

SYNOPSIS. 06/814 AM.

An eastern Pacific storm system will bring increasing clouds today with rain becoming likely between tonight and Saturday and snow above seven thousand feet. Showers will linger into Sunday, then a general warming and drying trend starts next week.

SHORT TERM (TDY-MON). 06/204 PM.

A small area of light rain came through early this afternoon, even sooner than the high res models were showing this morning. Amounts were under a tenth of an inch. Not seeing much immediately behind this but models are showing increasing moisture and shower chances later on tonight especially south of Pt Conception and across nw SLO County. However, given the events from today do not have any confidence on timing these waves as they move through. Overall, it still looks like a damp weekend with on and off light showers. Latest model output suggests forecast amounts might be on the high side but either way impacts will be minimal.

Models definitely in better alignment today showing more of westerly track to the main upper trough coming through Sunday and Sunday night. This provides a little more upper support for showers in the form of colder and more unstable air aloft.

All precip should be over by Monday with the trough axis south of LA County. Will likely have some lingering upslope clouds near the Grapevine and some breezy northerly winds but otherwise dry.

Snow concerns minimal as well as snow levels will be at or above 8000' through Saturday night then lowering to between 6000-7000' Sunday. No snow expected on the Grapevine and a few inches at higher elevations.

LONG TERM (TUE-FRI). 06/210 PM.

Still looks like a dry pattern through next week though models have scaled back on the strength of the ridge later in the week. A weak trough will pass north of the area Wednesday and increase high clouds but no precip. Temps will warm up to above normal levels Tuesday and remain that way through Friday.

AVIATION. 07/0001Z.

At 2330Z, there was no marine inversion at KLAX.

Overall, low to moderate confidence in 00Z TAF package. High confidence in VFR conditions for all sites through early this evening. Late this evening through Saturday afternoon, high confidence in development of light rain, but low confidence in timing of rain as well as associated CIG/VSBY categories (MVFR likely with a chance of IFR, and a small chance of VFR at times especially for KBUR, KVNY and KLGB).

KLAX . Overall, moderate confidence in 00Z TAF. High confidence in VFR conditions through this evening. For tonight, high confidence in light rain developing, but low confidence in timing. As for CIG/VSBY categories, high confidence in MVFR conditions overnight and Sat, but low confidence in timing of flight category changes. Moderate confidence in easterly winds around 8 knots after 08Z.

KBUR . Overall, moderate confidence at best in 00Z TAF. High confidence in VFR conditions through this evening. For tonight, high confidence in light rain developing, but low confidence in timing. As for CIG/VSBY categories, high confidence in MVFR conditions late tonight and Sat (with a small chance of IFR conditions, and even VFR conditions at times), but low confidence in timing of flight category changes.

MARINE. 06/1225 PM.

For the Outer Waters, moderate to high confidence in current forecast. Gusty southeast winds will continue through Saturday with a 70% chance of Gale force winds across PZZ670, an 80% chance of SCA level wind and seas across PZZ673 and a 40% chance of SCA level winds across PZZ676 (mainly north of San Nicolas Island). On Tuesday and Wednesday, there is a 60% chance of SCA level winds across PZZ673 and PZZ676.

For the Inner Waters north of Point Sal, moderate to high confidence in current forecast. There is an 80% chance of SCA level winds and seas tonight through Saturday morning. There is a 50% chance of SCA winds continuing into Saturday afternoon. For Sunday through Wednesday, high confidence in winds and seas remaining below SCA levels.

For the Inner Waters south of Point Conception, moderate to high confidence in current forecast. There is a 50% chance of SCA level southeast winds across the western half of the Santa Barbara Channel tonight through Saturday morning. Otherwise, high confidence in winds and seas remaining below SCA levels through Tuesday. On Wednesday, there is a 50% chance of SCA level northwest winds across the western half of the Santa Barbara Channel.

BEACHES. 06/1225 PM.

A large, long-period, west to northwest swell will bring high surf conditions to the Central Coast as well as the Ventura county coast tonight through Sunday morning.

For the Central Coast, surf heights will peak between 9 and 12 feet with local sets to 16 feet. For west-facing beaches of Ventura county, surf heights between 4 and 7 feet with local sets to 9 feet can be expected. For these areas, HIGH SURF ADVISORIES will remain in effect through Sunday morning.

For the west-facing beaches of southern Santa Barbara county and Los Angeles county, elevated surf conditions can be expected through Sunday with surf heights of 3-6 feet for Los Angeles county and 2-5 feet for southern Santa Barbara county.

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.

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.
