Area Forecast Discussion...UPDATED National Weather Service Los Angeles/Oxnard CA 1101 PM PDT Wed Mar 27 2024
SYNOPSIS
27/231 PM.
Expect cooling temperatures ahead of a storm which will affect the region over the weekend. A weaker rain band will pass over the San Luis Obispo and western Santa Barbara Counties tonight through Friday. The main storm will affect the whole area with rain and mountain snow, gusty winds, and isolated thunderstorms from Friday to Monday.
.SHORT TERM (WED-SAT)...27/1037 PM.
***UPDATE***
Marine layer clouds and fog worked their way into portions of the Central Coast this morning as a ridge of high pressure hangs onto the region. Temperatures warmed 3-8 degrees over the interior under mostly sunny skies. Clouds are increasing over the area this evening as a weak cold front approaches, bringing rain chances to San Luis Obispo, Santa Barbara and interior portions of Ventura and LA Counties. Things still look on track, but may need to move back the timing of rain to begin closer to 5AM as most of the rain remains north of Salinas. Rain chances linger over the interior and mountains of Ventura and LA County Thursday, with higher elevation snow for the mountains. Shortly after, the next low pressure system slides down the California Coast bringing more rain and gusty winds. Will likely need some wind advisories as the system moves through, especially for the Central Coast and higher terrain.
***From Previous Discussion***
Synoptically, the area is under a positively tilted east-pac ridge between a 521 dam upper-level low pushing down from the Gulf of Alaska to the west and a trough extending through all of central CONUS to our east. A weak frontal band will swing through the northern portion of the CWA tonight and Thursday producing some light precipitation. By Friday the low will have filled to about 536 dam and be west of San Francisco and an associated front will move through the CWA Friday and Saturday. The low will still affect our weather on Sunday from an offshore position just to our southwest before moving eastward, where it could drive some northslope activity similar to last week's. Once the ridge re- established itself overhead on Tuesday, it should remain there through Thursday before another system makes its way down the coast potentially bringing more rain next weekend.
High clouds have increased throughout the day ahead of the weak weather system set to arrive in SLO Co later tonight. High- res ensembles are keeping the rain for the northern areas tonight through Thursday night. Amounts will likely be a quarter inch or less, with most locales only receiving a few hundredths. Stratus clouds will become more organized tonight and into Thursday as an eddy circulation develops in the southern California bight.
Thursday's rain should stay confined to SLO and western Santa BArbara Counties. Temperatures will remain below seasonal normal and skies will remain partly to mostly cloudy. Marine layer induced low clouds and fog will spread well into the coastal slopes by late Thursday night or early Friday morning. Night through morning drizzle cannot be ruled out for Thursday night and Friday as the marine layer depth could approach 4000-5000 feet deep.
The more significant storm system will push into the region on Friday. All the GEFS, EPS, and CMC forecast ensemble members indicate rain developing at central California terminals starting Friday, spreading south into the remaining areas into Saturday.
The higher precip amount ensemble members have moved much more towards their mean, for a more confident forecast in rain amounts. The forecast keeps a slight chance of thunderstorms beginning late Friday, but they are much more likely (10-20%) after the front has moved through, later on Saturday. Thunderstorms and ensemble precipitable waters values approaching 1 inch indicate brief heavy downpours with small hail are possible.
Friday afternoon will also bring gusty southerly winds across the area, especially over the higher terrain, across the interior portion of the area, and for San Luis Obispo and Santa Barbara Counties.
Rain and mountain snow with a slight chance of thunderstorms will move into the southern areas on Saturday, along with the possibility of gusty southerly winds. The threat for brief heavy downpours causing minor flooding and small hail will shift south into the Southland. Roadway flooding will be a particular hazard on Saturday, so if you are planning to travel into or out of southern and central California, plan for more time to reach your destination over the weekend. Snow levels will drop to around 4500 feet, affecting the higher mountains roadways, such as Angeles Crest Highway and Highway 39 in Los Angeles County, and Lockwood Valley Road in Ventura County. There is a moderate to high chance that the snow level could lower enough to affect the lower mountain passes, such as the Tejon Pass on Interstate 5 near the Kern-Los Angeles County border and Highway 33 in Ventura County.
All EPS members are indicating snow for Sandberg (KSDB) as early as Saturday afternoon. A Winter Storm Watch may be needed by Thursday for some mountain areas due to the potential of significant snowfall above 6000 feet and gusty winds with the storm system.
.LONG TERM (SUN-WED)...27/236 PM.
The precip will likely remain through showers on Sunday with the low to our southwest, and even into Monday as it moves to the east setting up a pattern favorable for north slope precip in the mountains of LA, Ventura, and SBA Counties. Unlike the last low that then stalled around the CA- AZ border, this one should kick out to the east and we will see the ridge re- establish over the area for Tuesday and Wednesday at least, bringing a warming and drying trend.
Another system could be heading down the west coast by next Friday with another period of rain.

Low confidence in TAF package due to uncertainty with cigs and vsby tonight. Expect mostly MVFR to IFR cigs, with 10-20% chance of dense fog for all coasts and valleys from 06Z-17Z. Light rainfall is expected starting around 06Z for SLO County portions of SBA County by around 12Z.
KLAX...Low confidence in TAF. Cig arrival may be off by +/- 2 hours with a chance of BKN015 cigs to start before lowering to BKN004. There is a 20% chance of dense fog from 06Z-17Z, and a 10% chance for an 8 kt easterly wind component wind between 12Z-16Z.
KBUR...Moderate confidence in TAF, there is a 30% chance of BKN004-BKN015 cigs from 10Z-16Z.
MARINE
27/1059 PM.
Small Craft Advisory (SCA) level winds are expected to start Thursday morning, first impacting in the Santa Barbara Channel, spreading to to all the waters in the afternoon. SCA winds will last through Friday morning for the southern outer waters. For the northern outer waters and the inner waters north of Pt.
Sal, there is a 40% chance of SCA level winds dropping off Thursday night however seas should reach SCA level as winds drop off.
Late Friday through Friday night, as a front moves into the waters, the next period of SCA level winds (SE-S) is likely (60-70% chance) in the outer waters and the inner waters N of Pt Sal. SCA winds are expected (70% chance) to reach the SBA Channel Friday night, and there is a 50% chance for the southern inner waters. SCA conds may persist (60% chance) for all the waters through Saturday, and for the outer waters through Sunday.
There is a 10-20% chance of thunderstorms Sat thru Sun.
BEACHES
27/1041 PM.
A return of high surf is expected between Thursday afternoon and the weekend as a storm system will bring a large northwesterly swell to the region. Surf as high as 8 and 12 feet with local sets to 13 feet is expected at Central Coast beaches, and 4 to 7 feet with local sets to 8 feet for Ventura County beaches. Los Angeles and Santa Barbara South Coast will see surf 3 to 6 feet, with local sets to 7 feet. Surf should peak on Saturday or Saturday night. Strong and dangerous rip currents are expected during this period.
