Area Forecast Discussion National Weather Service Los Angeles/Oxnard CA 946 AM PDT Thu Sep 23 2021

SYNOPSIS. 23/944 AM.

A cooling trend will continue today as onshore flow strengthens ahead of an area of low pressure over the Great Basin. This trough will back into the region through the weekend and a cooling trend will likely linger. Another area of low pressure will keep temperatures below normal through the middle of next week.

SHORT TERM (TDY-SAT). 23/941 AM.

Cooling trend to finally make it inland today as onshore gradients to the east are significantly stronger. Look for coastal valleys to cool by 5-10 degrees on average. Elsewhere either similar or slightly cooler. Cooling to continue Fri and Sat with coastal temps dropping a few degrees below normal, however remaining slightly above normal for inland areas.

Smoke from fires in the southern Sierra is pouring into the area. Smoke models keeping most of it aloft except across the Antelope Valley and in the mountains where some of it may reach the surface. Expect smokey skies to linger through Friday night with some improvement possible in southern areas Saturday as winds shift to the east in response to a weak cut off low developing over northern Baja.

The easterly flow will usher in some moisture aloft late Friday into Saturday but models still keep the low too far south to have much impact here. At this point chances for rain/storms appear to be too low to keep in the forecast. Will probably see some mid/high clouds at times across LA/Ventura Counties.

LONG TERM (SUN-WED). 23/332 AM.

After Sunday, the operational model solutions diverge more as ECMWF solutions are more progressive with the cutoff trough's movement. GFS solutions are tending to be slower with the trough movement. Given the history of cutoff troughs in the region, the GFS solution could end up playing out. Ensemble members both of the ECMWF and GFS solutions seem to favor cooling extending for early next week, but there is some variance of the ensemble members toward the warm side. For now, the forecast keeps consistent with a cooling trend for early next week.

By midweek, a majority of the ensemble members of the GFS, ECMWF, and CMC are indicating the possibility of another trough bring light rain or showers to the region. Ensemble indicate light rainfall occurring between Tuesday and Wednesday. Run-to-run consistency is lacking in the operation model runs, but confidence is moderate in a very deep marine layer (around 3000 or 4000 feet deep) developing during this time period. Precipitation could end up being night through morning drizzle and/or showers along the coastal slopes of the mountains, but there are some members which lean toward amounts between a tenth and a half inch. Higher confidence exists for a continued cool weather pattern with gusty winds over the northern areas as a frontal boundary fall apart just north of the area. Almost all ensemble members indicate the possibility of advisory level wind gusts possible along the Central Coast and extending into southern Santa Barbara County Wednesday into Thursday. This will need to be monitored over the next several days as the model performance issues should improve between Friday and Saturday.

AVIATION. 23/1227Z.

At 12Z, the marine layer was around 1100 ft deep at KLAX. The top of the inversion was around 1700 ft with a temp of 26 C.

Low clouds were widespread of the Central Coast, in the Santa Ynez Valley, on the south coast of SBA County, and across coastal sections of Ventura County. Clouds have spread into portions of the Ventura County valleys and the immediate coastal sections of L.A. County. Conds were mostly LIFR to VLIFR. Skies should clear in most areas by mid to late morning, though cigs could linger at the beaches into the afternoon. Expect widespread low clouds in all coastal areas tonight, in the Santa Ynez Valley, and portions of the Ventura County valleys and the San Gabriel Valley tonight. Conds should be mostly IFR to VLIFR conds.

KLAX . Low to moderate confidence in the 12Z TAF. There is a 20-30% chance that cigs this morning will clear as early as 14Z. There is a 30% chance that cigs tonight will arrive as early as 05Z.

KBUR . High confidence in the 12Z TAF with VFR conditions thru the period.

MARINE. 23/326 AM.

Moderate to high confidence that Small Craft Advisory (SCA) level winds across the southern two outer waters zones (PZZ673/676) will decrease below SCA levels by mid morning. Otherwise and elsewhere, expect winds and seas to remain below SCA level through Monday. However, short-period, choppy, wind-driven seas will continue across the waters today. With the shallow marine layer, there will likely be patchy dense fog with visibility one nautical mile or less across the coastal waters at times thru Fri night.

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

.HAZARD POTENTIAL OUTLOOK (SAT-WED).

No significant hazards expected.
