Area Forecast Discussion National Weather Service Los Angeles/Oxnard CA 153 PM PST Tue Mar 2 2021

SYNOPSIS. 02/152 PM.

Today will be warm and dry with breezy offshore flow. A weak storm system may bring light to moderate rain and a thunderstorm to the area on Wednesday, mainly closer to Los Angeles County. Warming and drying Thursday and Friday. Another weak system may bring light rain to the area on Saturday, closer to San Luis Obispo County. Gusty west to northwest winds to follow through next Tuesday.

SHORT TERM (TDY-FRI). 02/1248 PM.

A low pressure system, currently centered 600 miles west of Los Angeles, will move in and through southern California tomorrow afternoon and evening. Areas north of the core will see little to no rain tomorrow, while areas in and south of the core will see rain. This means that how the rain will play out is highly sensitive to the precise track of the storm. The current trajectory has the core going through somewhere over Los Angeles or Orange County. If it is more towards Orange County, LA County will see significantly less than advertised. If it tracks more towards Ventura County, chances and amounts of LA and Ventura County will need to be upped. As such, keeping highest PoPs and rain amounts over eastern LA County, with generally 0.10 to 0.50 inches of rain. Areas north of that will see 0.10 or less if any. Snow levels should be around 5000 feet for the bulk of precip, so 2 to 4 inches of snow above those elevations are possible over the San Gabriel Mountains. Will be issuing a Winter Weather Advisory to cover that, and some gusty southeast winds over the mountains. Gusty southeast winds are also expected over much of LA and Ventura Counties at times, which may impact travel at LAX airport. Otherwise, all areas will see a drastic 10 to 20 degree cool down compared to today, along with way more clouds.

Any showers should quickly end by later Wednesday evening, with gusty sub-advisory winds filling in the interior valleys of San Luis Obispo and LA Counties. High pressure will then quickly build over the region Thursday and Friday, along with some locally breezy but sub-advisory east winds. This should bring healthy warming each day Thursday and Friday, with highs approaching 80 by Friday in the warmest spots.

LONG TERM (SAT-TUE). 02/1255 PM.

A trough of low pressure will push through northern California early Saturday, with a decaying cold front moving down the coast. Not expecting precipitation from this front being much, and at this points looks to dissipate by it enters Santa Barbara or Ventura County. What is more impactful from this is the wind. Gusty west to northwest winds are expected to quickly form on Saturday and Saturday night behind the front, impacting most coastal and interior areas. Wind Advisories are possible, especially over Santa Barbara County. These winds look to persist through Tuesday. Temperatures will drop down to below normal on Saturday with the cold front, and should wobble around seasonal norms into next week. Still looking at a potential change to a wetter pattern for the middle to end of next week.

AVIATION. 02/1843Z.

At 1600Z at KLAX, there was no marine layer nor an inversion.

High confidence in all TAFs through 15Z. Moderate confidence in timing of showers south of Point Conception and a slight chance of thunderstorms for KLGB. KLAX . High confidence in TAF before 15Z, moderate confidence in timing of showers and cig heights. Any east wind component will be under 6kts.

KBUR . High confidence in TAF before 17Z, then moderate confidence.

MARINE. 02/113 PM.

Outer Waters . Good confidence in winds and seas forecast. Small Craft Advisories (SCA) are not expected through the week however winds may be gusty at times Wednesday afternoon into the evening as a low pressure system moves through the southern portion of the region. This low will bring a 15% chance of a thunderstorms south of San Nicolas Island. Seas will increase into Wednesday, but are expected to remain below 10 feet. By Friday, a larger swell will bring the potential of 10 to 12 foot seas throughout the outer waters. NW winds will likely reach SCA levels Saturday.

Inner Waters N of Point Sal . Good confidence in winds and seas forecast. Small Craft Advisories (SCA) are not expected through the week. The chance for SCA hazardous seas and winds starts Friday night into Saturday.

Inner Waters S of Point Conception . Moderate confidence Wednesday as a storm will move across the area during the afternoon. There is a 20% chance of S-SE 25 kt gusts across the San Pedro Channel during the day, but guidance is trending towards lighter winds so holding off on a SCA. There is a 15% chance of thunderstorms for the LA and Orange County Coast Wednesday afternoon. The next chance for SCA winds is Saturday, and seas will begin to near 7 feet over the weekend.

LOX WATCHES/WARNINGS/ADVISORIES. CA . Winter Weather Advisory in effect from 1 PM to 10 PM PST Wednesday for zone 54. (See LAXWSWLOX). PZ . NONE.

.HAZARD POTENTIAL OUTLOOK (FRI-TUE).

High surf and dangerous rip currents are likely Thursday night through the middle of next week. Possible light rain on Saturday could create hazardous road conditions. Gusty west to northwest winds will create driving and boating hazards Saturday through at Tuesday.
