SYNOPSIS
05/216 PM.

Locally gusty northeast winds will weaken this evening, with mostly clear skies continuing into tonight and Wednesday morning.
A weather disturbance will affect the region later Wednesday into Thursday, bringing cooler temperatures and scattered light showers over portions of the area. Drier conditions and strengthening offshore flow are expected by Friday, continuing into this weekend and next week. A warming trend is expected to commence by late this weekend.

.SHORT TERM (TDY-FRI)...05/216 PM.

Gusty northeast to east-northeast winds continue early this afternoon through the Santa Clarita Valley to the Santa Susana Mountains and vicinity. Gusts in this area have generally ranged from 30 to 35 mph, and should subside this evening into tonight as offshore pressure gradients have already started to weaken and will continue to do so. Otherwise, skies will remain mostly clear through tonight and into Wednesday. However, with the onset of midlevel height falls on Wednesday and weakening offshore gradients, Wednesday high temperatures will cool by a few degrees compared to those of Tuesday. Regardless, Wednesday high temperatures should still reach the 70s in many areas, except cooler toward the beaches and over the mountains.

By Wednesday night, deep cyclonic flow aloft that has been persistent over the north Pacific waters is forecast to begin gradually shifting eastward, in response to a strong upper-level jet streak progressing through its broad base. The main track of the jet streak and accompanying midlevel height falls will remain north of the region. However, the glancing influence of these features will bring changes to sensible weather conditions along their southern peripheries and across southern California for mid to late week.

Surface pressure gradients are expected to turn onshore Wednesday night into Thursday as surface pressure falls beneath the left- exit region of the midlevel speed maximum track eastward over the northwest CONUS. As a result, low clouds and fog are expected to overspread the Central Coast and nearby valleys, along with coastal LA County and nearby inland areas, in response to the marine layer extending farther inland. Continued midlevel height falls, the influx of the marine layer, and some high clouds will collectively result in high temperatures Thursday cooling by several more degrees in most areas. High temperatures on Friday are forecast to change minimally from Thursday into Friday, remaining a few degrees below normal in many areas, as midlevel troughing is reinforced over the western states.

The bulk of precipitation accompanying large-scale ascent should remain north of the forecast area. However, the southern end of an area of showers accompanying a warm conveyor structure, along the leading edge of cyclonic flow aloft, may graze coastal San Luis Obispo County as early as Wednesday mid-day and continue at times into the evening. Precipitation in this regime will be light, with totals below one-tenth inch expected. Thereafter, from Wednesday night into Thursday, reinforcement to western-CONUS upper troughing along with increasing upslope flow along the Transverse Ranges will support 20-30-percent chances for light showers spreading over the mountains of Santa Barbara and Ventura Counties and toward the the Interstate-5 corridor. Precipitation in this regime will also be light, with totals below one-tenth inch. Snow levels through the duration of this precipitation will generally be around 6000-6500 ft, keeping any very light snow showers confined to the highest elevations. Precipitation should end by Thursday night as subsident flow aloft and drier air overspread the region.

Meanwhile, the previously mentioned late-week reinforcement to western-CONUS troughing will be followed by an extended duration of longwave troughing over the central and eastern United States, while a midlevel anticyclone builds over the Pacific waters off the southern California coast. This stable longwave pattern will encourage the expansion of a strong surface ridge across the Great Basin starting late this week. In response to these developments, pressure gradients are expected to quickly turn offshore Thursday night into Friday. LAX-DAG offshore gradients are forecast to quickly fall to 3-6 mb by Friday, 3-5 mb SBA-BFL and 2-4 mb SBA- SMX. And with ample upper support over the region from the midlevel speed maximum reorienting to more northwesterly, a moderate to locally strong offshore wind event is expected to begin Thursday night, and continue into Friday and beyond.
Probabilities are high (60-80 percent) for widespread Wind Advisories to become necessary for the mountains and foothills of Santa Barbara, Ventura, and Los Angeles Counties starting on Thursday night or Friday, perhaps extending toward the coast in more wind-prone areas. There is also a 20-40 percent chance for local gusts to reach 60-70 mph over areas particularly prone to more northerly surges of offshore flow such as Montecito Hills and the I-5 corridor.

.LONG TERM (SAT-TUE)...05/216 PM.

Moderate to locally strong offshore flow is expected to continue into this weekend and next week, as ensemble model guidance indicates the large-scale pattern undergoing little overall change. Persistent warming from downslope flow in many of the lower elevations, combined with continued midlevel ridging offshore that will brush southern California, should allow temperatures to rise to several degrees above normal by late this weekend into early next week. Dry conditions are expected to prevail across the region. Model cluster analysis indicates a small subset of solutions amplifying the large-scale central/eastern-CONUS trough southwestward over the region toward the end of the period. While this casts some uncertainty on how warm the temperatures will be at the end of the period, these solutions suggest that dry conditions should prevail.

AVIATION
05/1805Z.

Around 18Z at KLAX, there was a surface based inversion with a top at 1500 feet with a maximum temperature of 22 C.

High confidence in VFR TAFs.

KLAX...High confidence in TAF. There is a 20 percent chance of some marine clouds late tonight. There is a 30% chance of an east wind component of 5 kts through 17Z Tues.
KBUR...High confidence in TAF.

MARINE
05/1243 PM.

For the Outer Waters, moderate to high confidence in forecast.
Winds are expected to remain below Small Craft Advisory (SCA)
levels through Wednesday morning. However, SCA level seas are expected into Saturday, with a dip below advisory levels possible this afternoon. There is a 50% chance of SCA level winds returning to the waters south of Point Conception as early as Wednesday afternoon. Then, winds will expand across all the outer waters overnight Wednesday and continue through Friday, with a 40% chance of Gale Force winds Thursday afternoon into Friday morning. There is a 30-40% chance of SCA winds continuing through Saturday with a brief decrease below advisory levels possible Friday night.

For the Inner Waters north of Point Sal, moderate confidence in forecast. Seas are expected to be at or near SCA level through early this morning. However, there is a 40-50% chance of SCA level seas returning tonight and lasting through Friday. Winds are expected to be below advisory levels through Thursday morning with a 30-40% chance of winds increasing to SCA levels Thursday afternoon into early Friday morning.

For the Inner Waters south of Point Conception, moderate to high confidence in forecast. There is a 15% chance of SCA level NE winds from Ventura south to Malibu this morning. There is a 30-40% chance of NW SCA level winds across the western portion of the Santa Barbara Channel on Wednesday during the afternoon/evening hours, and the western portions of all the southern inner waters during the same hours on Thursday. Late Thursday night into Friday morning, there is a 20% chance of strong SCA level N to NE winds across the eastern portions of the waters.

BEACHES
05/1243 PM.

A long period NW swell (17-19 seconds) will result in high surf of 8 to 11 feet to west- and northwest-facing Central Coast beaches this morning. Surf may subside briefly this afternoon before the next system of long period NW swell (18-21 seconds)
arrives tonight and lasts through Thursday.

Peak wave heights will occur tonight through Thursday. Expect 10 to 14 feet for the Central Coast beaches, 4 to 7 feet with local sets to 8 feet for Ventura County beaches, and elevated surf for LA County beaches. Surf heights will be highest across west and northwest facing beaches. Due to low astronomical tides, coastal flooding is not expected.
