Area Forecast Discussion National Weather Service Los Angeles/Oxnard CA 1139 AM PDT Sat Oct 23 2021

SYNOPSIS. 23/415 AM.

Very quiet weather is expected through Sunday afternoon, with partly to mostly cloudy skies. An approaching storm will bring widespread moderate to heavy rain Sunday night and Monday, along with gusty winds and cooler temperatures. Warming and drying are expected the rest of next week.

SHORT TERM (TDY-MON). 23/756 AM.

There was a low level moist layer over the forecast area early this morning, with varying amounts of low clouds and fog noted the coast, vlys and into the mtns. Some drizzle and very light rain persisted this morning in some areas as well. The low clouds are expected to persist this morning before decreasing in coverage this afternoon, with any leftover drizzle or light rain ending before noon. Otherwise, partly cloudy skies should prevail for the most part thru today as hi clouds drift overhead from time to time. Gusty NW winds can be expected today for southern SBA County, especially W of Goleta, and also along the I-5 corridor in the mtns. Gusty W-SW winds will also prevail across the Antelope Vly for much of today. Temps today will be about 5-10 deg below normal in all areas, with highs in the warmest vlys and inland coastal areas in the upper 60s to lower 70s.

A mostly a zonal flow aloft is expected to persist over the forecast area thru tonight, with H5 heights about 574-579 dam from N to S thru the period. The flow aloft will turn more to the SW on Sun as a large upper level trof over the E Pac approaches the CA coast.

There should be plenty of clouds over the fcst area tonight thru Sun, including low clouds along the coast and into some of the vlys overnight into Sun morning. In addition, a warm front associated with a Pacific storm system will approach the Central Coast on Sun, with increasing chances of rain expected mainly over SLO County thru the afternoon. Gusty NW winds can be expected this evening for southern SBA County and in the mtns along the I-5 Corridor, likely to Advisory levels for the Santa Ynez mtns. For Sun afternoon, winds are expected to switch so SW and become quite gusty by late in the day, especially over SLO County. High temps on Sun are expected to remain about 5-10 deg below normal across much of the region.

The large eastern Pac upper level trof is forecast to move E to just off the CA coast Sun night, then move quickly E thru the state Mon and Mon evening. A strong early season storm system associated with this upper level trof will move into SW CA during the period. The main cold front is forecast to push into SLO County late Sun night or early Mon, into SBA County early to mid Mon morning, and thru VTU/L.A. Counties Mon afternoon and early evening. It looks like moderate to heavy rain will affect SLO County Sun night, especially across western areas into the Santa Lucia Range. Moderate to occasionally heavy rain will affect SBA County by early Mon morning, followed by mainly moderate rain into VTU/L.A. Counties starting mid to late Mon morning. The rain will taper off from NW to SE across the forecast area thru Mon afternoon, with lingering chances of rain over VTU/L.A. Counties into Mon evening.

Snow is not going to be a factor with this weather system as snow levels should remain well above 8000 feet until the tail end of the event Mon evening. In addition, the coldest air and most unstable airmass with this storm will remain over northern and central CA thru Mon and no thunderstorms are expected for the forecast area.

Strong and gusty S to SW winds ahead of the main front can be expected across the region Sun night and Mon. Winds may even reach High-end Advisory levels for much of SLO/SBA Counties later Sun night into Mon morning, and Wind Advisories will likely be needed.

Preliminary rainfall amounts for this storm system from Sun night into Mon evening continue to be about 1.00-3.00 inches across SLO/SBA Counties, and 0.50-1.50 inches for VTU/L.A. Counties with local higher amounts over 1.75 inches. The highest rainfall totals will be along south and southwest facing slopes, such as the Santa Lucia Range and Santa Ynez Mtns. Recent burn areas will be susceptible to minor mid and debris flows, especially in and around the Alisal burn area in southern Santa Barbara County. Projected rainfall intensities of 0.25 to 0.50 inch per hour with local intensities up to 0.75 inch per hour are below USGS thresholds for more impactful mid and debris flows. However, this situation will be closely monitored for any changes as we draw closer to the event.

As far as temperatures, it will turn even cooler on Mon with the clouds and rain over the region. Highs will be about 7-14 deg below seasonal norms, and only reach into the upper 50s and 60s for the coast and vlys.

LONG TERM (TUE-FRI). 23/149 AM.

By Tuesday, the upper-level trough will have raced well east and out of California. In its wake, weak ridging will develop through Friday. This will bring us back into a warm and dry pattern. Flow will reverse from onshore to weakly offshore, likely keeping low clouds away through the week. The ECMWF is more bullish with offshore flow through the week, forecasting a LAX-DAG gradient peaking at -5.4 mb on Thursday morning which has been fairly consistent run to run. A quick glance at the ensemble solutions show decent agreement between members for the potential for breezy offshore winds through the typical Santa Ana corridors. The GFS on the other hand is not as excited about it, so confidence is not great at this point. Regardless, this will be worth watching as timing gets closer, especially as conditions dry out. Rising heights and offshore flow will bring a nice warming trend through the end of the week with temperatures rising around 4 to 8 degrees each day through Thursday, then leveling off by Friday. Temperatures will warm back up into the mid- to upper-70s for most areas, and the lower to mid-80s for the warmest valley spots.

AVIATION. 23/1836Z.

At 1757Z at KLAX, there a deep moist layer with a depth of 4600 feet.

Moderate confidence in the 18z TAFs, except low confidence in the LA valleys.

Low clouds were persistent in the coastal and valley sections of LA and Ventura counties and may last all day. Residual moisture will allow for redevelopment or an extension of cloudy skies tonight. Again, the situation will be uncertain for the LA valleys as there is a 50 percent chance of VFR conditions there tonight.

Generally hi confidence at KPMD, KWJF with VFR conditions thru the period. Strong and gusty SW winds will prevail today into this evening for KPMD and KWJF.

KLAX . Moderate confidence in the 18Z TAF. Low clouds and fog with a mix of MVFR and VFR cigs can be expected thru 18Z Sun morning. Timing between flight cats may be off several hours. East wind component should remain below 6 kt Sun morning.

KBUR . Low confidence overall in the 18Z TAF. There is a 50 percent chance of VFR conditions tonight.

MARINE. 23/1121 AM.

Moderate to high confidence in Small Craft Advisory (SCA) winds 20 to 30 knots continuing for the outer waters through tonight. SCA is also in effect for the western portions of the southern inner waters. The winds will generate choppy seas over all waters through at least tonight, with 3 to 5 foot 6 second period waves common. High confidence in a long period swell leading to greater than 10 foot (SCA threshold) seas off the Central Coast through Saturday.

A storm system is still on track to impact the area Sunday and Monday. This storm will bring a period of gusty SW winds everywhere, including a 70 percent chance of 6 or so hours of Gale Force Winds north of Point Arguello Sunday Night. This storm will also bring a large swell impacting all areas by Monday and last through Wednesday, peaking Monday afternoon through early Tuesday. During this peak, large breaking waves will pose dangers to boats and divers nearshore, with breaking waves possible over the Morro Bay and Ventura Harbor entrances. The chance of thunderstorms is minimal.

BEACHES. 23/1138 AM.

High Surf Advisories are in effect for the Central Coast and Ventura County, with a Beach Hazards Statement for Los Angeles County (which is likely to be borderline High Surf). This is to cover the increasing surf through 10 pm tonight, but also to message the larger more impactful swell and surf for Monday and Tuesday.

Moderate to high confidence in a very large west-northwest swell peaking at 15 to 20 feet with a 17 second period over the Central Coast, with about half those heights for the inner waters from Santa Barbara to Orange County. The peak of the swell will be Monday afternoon through early Tuesday morning. A swell this size will result in High Surf Advisories and dangerous currents over nearly all coasts. There is a chance that surf heights reach around 20 feet on the Central Coast, which could result in damage to coastal structures like piers. A High Surf Warning will be considered in the coming days.

LOX WATCHES/WARNINGS/ADVISORIES. CA . High Surf Advisory in effect until 10 PM PDT this evening for zones 34-35-40. (See LAXCFWLOX). Beach Hazards Statement in effect until 10 PM PDT this evening for zones 41-87. (See LAXCFWLOX). PZ . Small Craft Advisory in effect until 9 PM PDT this evening for zones 645-650-655. (See LAXMWWLOX). Gale Watch in effect from Sunday evening through late Sunday night for zones 645-670-673. (See LAXMWWLOX). Small Craft Advisory in effect until 3 AM PDT Sunday for zones 670-673-676. (See LAXMWWLOX).

.HAZARD POTENTIAL OUTLOOK (MON-FRI).

High surf and dangerous rip currents will affect area beaches through Wednesday, largest Monday and Tuesday with potential harbor closures. Moderate to heavy rain expected Monday with roadway flooding, possible shallow debris flows around the Alisal burn scar, and gusty winds focused in the mountains.
