Area Forecast Discussion National Weather Service Los Angeles/Oxnard CA 1140 PM PST Tue Dec 10 2019
SYNOPSIS. 10/827 PM.
Temperatures will trend warmer into Friday despite some periods of clouds as high pressure shifts off to the east. A large westerly swell is expected to arrive Thursday, bringing high waves to most coastal regions through the weekend. Additionally, breezy northerly winds will develop Wednesday and last into the weekend.
SHORT TERM (TUE-FRI). 10/801 PM.
***UPDATE***
Overall, a very quiet evening across the district. Latest satellite and surface observations indicate partly cloudy skies with varying amounts of high clouds moving overhead. Latest sounding data indicates decent inversion based around 1700 feet across the Central Coast, but a much weaker inversion based around 600 feet south of Point Conception. With gradients remaining weakly offshore or neutral overnight, do not anticipate much coastal stratus/fog. Best chances for low clouds and fog will be across the Central Coast and the interior valleys of San Luis Obispo county, but only a moderate confidence forecast. South of Point Conception, expect skies to remain stratus-free although there is a slight chance of some stratus/fog across the LA coast late tonight. As for winds, no issues are expected as current wind speeds are very light.
Current forecast has a good handle on the immediate short term. So, no updates are planned at this time.
***From Previous Discussion***
A weak trough and cold front are approaching from the west. The ridge over us today will hold together long enough to keep rain to the north but there will be some clouds and cooler temps with it on Wednesday.
Behind that Thu/Fri we'll see an increase in northerly winds, especially in favored areas like srn SB County and the I5 corridor but should be below advisory levels. At the same time an upper ridge will rebuild from the west and peak in strength on Friday. So between the ridge and light offshore gradients temps will warm up in all areas with Friday likely the warmest day we've seen since well back into November and also likely the warmest day of many after that as we shift into a much cooler pattern again next week.
LONG TERM (SAT-TUE). 10/147 PM.
The ridge will break down Saturday as the next trough drops in from the northwest. This one is not taking a favorable path for precip in our area but there could be some showers late Saturday near our shared border with Kern County, from southeast SLO County through the Grapevine area. Otherwise expect several degrees of cooling Saturday as onshore flow returns to lower elevations. Still gusty northerly winds expected in the mountains but likely below advisory levels on Saturday.
The trough passes through on Sunday which will provide a boost to the northerly flow already in place. Models showing anywhere from 5-7mb northerly gradient to BFL late Sunday into Monday and also 3-5mb SBA-SMX gradient so we'll likely see advisory level north winds developing in srn SB County and the I5 corridor and likely the Antelope Valley as well. Highs Sunday will drop a few more degrees as cooler air aloft moves in behind the trough passage putting most areas a few degrees below normal.
A brief upper ridge will move overhead Monday for slightly warmer temps and highs near seasonal norms. Northerly winds should decrease after the morning.
The models diverge Tuesday with the ECMWF showing a stronger and longer lasting ridge. However a vast majority of the ensembles support the cooler GFS solution which shows the next system rapidly approaching the Central Coast Tuesday with some rain chances there by afternoon. Those model differences continue through the end of the week with the deterministic EC favoring a dry/warmer pattern while the GFS and at least some of both ensembles much cooler with some precip at times.
AVIATION. 11/0740Z.
At 06Z, there was no marine inversion at KLAX.
Lots of high clouds across the region overnight, especially across northern sections. Expect stratus on the Central Coast and in the Santa Ynez and Salinas Valleys overnight and Wed morning. Conds will generally be IFR to LIFR, except VLIFR in the Salinas Valley. S of Pt Conception, patchy low clouds and fog are expected, and IFR to low MVFR cigs are a possibility late tonight/Wed morning at coastal TAFs in VTU and L.A. County.
KLAX . Moderate confidence in 06Z TAF. There is a 30% chance of IFR to low MVFR conditions between 09Z-17Z. No significant east wind component is expected.
KBUR . High confidence in 06Z TAF with VFR conds expected thru pd.
MARINE. 10/801 PM.
Moderate confidence that winds will stay under Small Craft Advisory (SCA) through Wednesday morning, with a long duration of SCA conditions likely starting Wednesday afternoon, which will continue through at least Sunday. These winds will be focused from the Central Coast to San Nicolas Island, but will affect portions of the Santa Barbara Channel and Santa Monica Basin at times, especially over the weekend when the winds peak. Short period choppy seas will become more prevalent everywhere.
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 is possible anywhere through at least Wednesday.
BEACHES. 10/801 PM.
A large long-period west to northwest swell will push on to the coast of central and southern California Thursday night, peak on Friday, then slowly diminish over the weekend. Surf will likely peaks Swells off the Central Coast will likely peak between 12 and 16 feet and 6 to 10 feet over the southern waters. High Surf Advisories will likely be needed over all beaches during the peak, with strong rip currents and dangerous breaking waves.
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. There is a small chance of more impactful flooding over vulnerable roads in the Ventura area.
