Area Forecast Discussion National Weather Service Los Angeles/Oxnard CA 415 PM PST Thu Jan 21 2021

SYNOPSIS. 21/135 PM.

Much cooler and unsettled weather is expected Friday through the weekend. There is a chance of light showers and mountain snow Friday afternoon through Saturday night. For Monday through Thursday, more significant rain and mountain snow is likely as a couple systems impact the area.

SHORT TERM (TDY-SUN). 21/135 PM.

Overall, 12Z models in good synoptic agreement through the short term period. At upper levels, low will develop along the NorCal coast tonight/Friday then will move southeast to south, reaching Arizona on Sunday. Near the surface, onshore flow will continue.

Forecast-wise, looking for very cool and unsettled weather Friday through the weekend. Main story will be the potential for some rain and snow across the area this weekend. As the upper low moves southward, a weak front will sweep across the area Friday and Friday night, bringing some light rain. Behind the front, a cold and unstable air mass will keep a threat of showers going through Saturday evening. At this time, do not anticipate this system to have a lot of moisture to work with. So, rainfall totals will not be too impressive with most areas receiving under one quarter inch of rainfall (with locally amounts up to around one half inch across the San Gabriel Mountains). However, given the cold nature of this system, snow levels will be an issues. On Friday, snow levels will range around 5000 feet, but will drop to near 4000 feet Friday night and Saturday. So, there could be some winter weather issues for the mountain passes, including the Grapevine area. Will need to monitor the potential need for winter weather products as we get closer to the event. Also, will need to watch for the potential for thunderstorms on Saturday as the cold and unstable air is overhead. Not confident enough to include any thunderstorm mention yet in the forecast, but future shifts may need to add some thunderstorms.

After a bit of a break Saturday night and Sunday morning, the next system will begin to impact the area Sunday afternoon and evening. Rain will become likely across San Luis Obispo and Santa Barbara counties late Sunday afternoon and evening with a chance of rain across Ventura and Los Angeles counties. Rainfall amounts Sunday afternoon and evening will range around one tenth of an inch across San Luis Obispo/Santa Barbara counties with a few hundredths possible across Ventura/Los Angeles counties.

As for temperatures, expect a very cool weekend for all areas. Afternoon temperatures will struggle in the 50 to lower 60s with cool overnight low temperatures.

LONG TERM (MON-THU). 21/135 PM.

Overall, the 12Z models continue to exhibit decent synoptic agreement through the extended period. At upper levels, another low will move over the area Sunday night through Tuesday morning, followed by another system Wednesday and Thursday. Near the surface, onshore flow will continue.

Forecast-wise, the cool and unsettled weather will continue. For Sunday night and Monday morning, cold front will sweep across the area, bringing a period of steady rain and snow. Behind the front, showery precipitation will continue through the Monday night/Tuesday morning time frame. Moisture with this system will be a little more impressive, resulting in some higher rainfall totals. Preliminary rainfall totals are expected to generally range between 0.25 and 0.75 inches with most areas receiving under 0.50 inches. Snow levels with this particular system will also be more impressive, dropping from around 4500 feet Sunday night to around 2000 feet Monday night and Tuesday morning. So, once again, there could be some winter weather issues for the local mountain passes. Also, once again, will need to monitor the potential for thunderstorm development on Monday as the cold and unstable air (associated with the low) moves overhead.

After a brief respite Tuesday afternoon/evening, attention turns to around system with the potential to be a significant rainfall producer on Wednesday/Thursday. At this time, the GFS and ECMWF differ on the timing and strength of this storm. The GFS is faster with the system, pushing the front through quicker and producing more rainfall. However, even the ECMWF solutions indicates pretty healthy rainfall for the area. Looking at the respective ensemble members, the potential for significant rainfall is supported by most ensemble members. Very preliminary rainfall estimates at this time range between 1 and 3 inches (with the potential for heavier amounts if the GFS is correct). Snow levels will continue to be on the low side, so some significant snowfall will be possible in the local mountains.

AVIATION. 22/0007Z.

At 2332Z at KLAX, there was no marine layer.

High confidence in VFR conditions for all sites through 04Z, then low to moderate confidence for coastal and valley sites. Low clouds appear likely for coastal sites, but lower confidence on timing which may occur +/- 2 hours of forecast. There is a 50% chance of low clouds reaching KBUR and KVNY.

KLAX . High confidence in TAF through 04Z, then moderate confidence. Low clouds may arrive between 05Z-09Z. There is a 20 percent chance of an east wind component greater than 7 kt after 08z.

KBUR . High confidence in TAF through 08Z, then low confidence in timing and occurrence of low clouds. There is a 50% chance of low clouds after 09Z.

MARINE. 21/222 PM.

High confidence in winds and seas remaining below Small Craft Advisory (SCA) levels for the inner and outer waters through Friday morning. By late Friday afternoon into Friday evening, moderate confidence in increasing winds and seas across the region. Northwest winds and seas should increase to SCA level from north to south along the Central Coast to San Nicolas Island, continuing through Saturday.

By Sunday night into Monday morning, stronger northwest winds will spread across all the coastal waters, bringing at least SCA level winds for the inner and outer waters. There is a good chance for widespread gales, especially for the outer waters. Along with the winds, a very large northwest swell should arrive arrive late Sunday to Monday morning, with swell heights greater than 15 feet appearing likely.

LOX WATCHES/WARNINGS/ADVISORIES. CA . NONE. PZ . NONE.

.HAZARD POTENTIAL OUTLOOK (SUN-THU).

Light to moderate precipitation and low elevation snow is possible Sunday night through Tuesday. A stronger system will impact the area Wednesday and Thursday with significant rain and mountain snow.

In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
