Area Forecast Discussion National Weather Service Los Angeles/Oxnard CA 907 PM PST Wed Dec 11 2019
SYNOPSIS. 11/907 PM.
Temperatures will warm through Friday as the region remains dry with periods of sunshine. A large westerly swell will bring high waves and surf from Thursday through the weekend, and light rain is expected Saturday in mountain areas. Areas of gusty winds will persist through the weekend and Santa Ana winds are expected to develop Monday of next week.
SHORT TERM (WED-SAT). 11/837 PM.
***UPDATE***
Overall, another quiet evening across the district. Latest satellite shows plentiful mid to high clouds moving over the area which will keep skies partly to mostly cloudy tonight. With respect to stratus, weak offshore flow should keep most areas stratus-free overnight. The only exception may be the interior valleys of SLO county and the Central Coast where patchy low clouds/dense fog will be possible later tonight. A stray light shower would not be out of the question across far northern SLO county overnight, but not enough concern for measurable rainfall to include in the forecast at this time.
As for winds, do not anticipate any significant issues overnight. Current observations indicate some gusty northerly winds across the mountains and SBA South Coast, but winds are generally below advisory levels. Overnight, expect the northerly flow to continue then shift more northeasterly towards morning. However, given weak gradients and limited upper level support, do not anticipate any widespread advisory-level north to northeast winds.
Current forecast looks to have very good handle on the immediate short term. So, no updates are planned at this time.
***From Previous Discussion***
Building high pressure aloft and light offshore flow through Friday will lead to significant warming the next couple days, peaking Friday with highs in the mid to even upper 70s in some of the warmer valleys of LA/Ventura Counties. These will be the warmest temps we've seen since before Thanksgiving and likely the warmest we'll see in the next week to ten days at least. High clouds will increase tonight into Thursday morning but should clear out for plenty of sunshine both days.
There will be some locally gusty northerly winds in the mountains and in srn SB County but speeds should be below advisory levels.
The ridge will break down Saturday and allow a weak front to pass through. Given the path this system is taking it doesn't have much moisture with it but as the moisture banks up against the north facing mountains from the Grapevine through southeast SLO County light showers are possible Saturday with snow levels possibly lowering to around 4000' (Grapevine level) by late Saturday night. Advisory level northwest winds possible Friday night into Saturday for the Grapevine and possible srn SB County and the Antelope Valley. Temperatures will cool several degrees Saturday as gradients turn onshore and cooler air aloft arrives with the front.
LONG TERM (SUN-WED). 11/152 PM.
Gusty northerly winds will continue in the mountains and srn SB County Sunday before shifting to northeast Monday and Tuesday. The ECMWF is much stronger with the offshore flow than the GFS and seems overdone given the more progressive upper level pattern and the EC ensembles. So breezy offshore winds are possible both days but below advisory levels. The air mass is much cooler than it will be this Thu/Fri so even with the offshore flow temps will still mostly be in the 60s at lower elevations which is near seasonal norms.
Models in better agreement Tue night into Wed now both showing a weak trough coming through. Not much moisture going for it and only a small chance of showers, better north of Pt Conception.
AVIATION. 11/2308Z.
At 2245Z, the marine inversion at KLAX was based at 700 feet. The top of the inversion was 1600 feet with a temperature of 18 degrees Celsius.
Overall, moderate to high confidence in 00Z TAF package. North of Point Conception, there is a 60% chance of VLIFR conditions at KPRB and a 50% chance of VLIFR conditions at KSMX. South of Point Conception, conditions are expected to remain VFR through TAF period.
KLAX . High confidence in 00Z TAF as VFR conditions are expected through the TAF period. There is a 10% chance of IFR/LIFR conditions 10Z-16Z. No significant easterly wind component is expected.
KBUR . High confidence in 00Z TAF as VFR conditions are expected through the TAF period.
MARINE. 11/836 PM.
For the Outer Waters, high confidence in current forecast. Small Craft Advisory (SCA) level winds will continue across PZZ673/676 through Thursday night then spread into PZZ670 on Friday. The SCA level winds will continue across all the Outer Waters through Sunday with a 50% chance of Gale force winds Saturday and Sunday. With the gusty winds, short-period, choppy seas will be likely.
For the Inner Waters north of Point Sal, moderate to high confidence in current forecast. There is a 50% chance of SCA level winds Thursday and Friday then a 70% chance of SCA level winds on Saturday and Sunday (with a 20% chance of Gale force gusts Saturday and Sunday). With the gusty winds, short-period, choppy seas will be likely.
For the Inner Waters south of Point Conception, moderate to high confidence in current forecast. There is a 30% chance of SCA level winds across the western half of the Santa Barbara Channel Thursday and Friday. From Friday night through Sunday, there is an 80% chance of SCA level northwest winds (especially across western sections) and a 30% chance of Gale force gusts. On Monday, the winds will shift to the northeast with a 50% chance of SCA level northeast winds on Monday.
A large and long period west to northwest swell will impact the coastal waters Thursday through Sunday, 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 are possible.
BEACHES. 11/836 PM.
A large long-period west to northwest swell will fill into the coastal waters of southwest California Thursday, peak on Friday, then slowly diminish over the weekend. Surf will likely peak between 12 and 16 feet and 6 to 10 feet over the southern waters. Will issue the High Surf Advisory for the Central Coast today, but will hold off on the southern beaches until tomorrow (since it starts later). Strong rip currents and dangerous breaking waves are expected.
With high tides around 6.5 feet Friday 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. A Coastal Flood Advisory may be issued tomorrow. There is a chance of more impactful flooding over vulnerable roads in the Ventura area.
LOX WATCHES/WARNINGS/ADVISORIES. CA . High Surf Advisory in effect from 6 AM Thursday to noon PST Monday for zones 34-35. (See LAXCFWLOX). Beach Hazards Statement in effect from Thursday evening through Sunday morning for zones 39>41-87. (See LAXCFWLOX). PZ . Small Craft Advisory in effect until 3 PM PST Saturday for zones 673-676. (See LAXMWWLOX).
.HAZARD POTENTIAL OUTLOOK (SAT-WED).
High surf is likely and minor coastal flooding is possible this weekend at area beaches. Strong northwest winds expected over the weekend in southern Santa Barbara County, and parts of LA/Ventura Counties.
