Area Forecast Discussion...UPDATED National Weather Service Los Angeles/Oxnard CA 508 PM PST Wed Nov 29 2023
SYNOPSIS
29/507 PM.
A few light showers are possible through this evening, mainly along the Central Coast and in the San Gabriel Mountains, as well as early Friday over the Grapevine. Otherwise, partly cloudy skies and cooler temperatures are expected through Saturday, along with increasing northerly winds. A warming trend is expected Sunday into early next week, with dry Santa Ana winds expected at times.
.SHORT TERM (TDY-SAT)...29/159 PM.
A couple of fairly weak shower bands are moving through the area today, mostly along the Central Coast and in the mountains. Little if rainfall expected elsewhere as the system is moving through from the northwest which is causing downsloping (drying) flow south of the mountains. Could see a stray sprinkle or two into the LA valleys this afternoon and evening but that's about it. The upper low itself continues to slide south well off the coast and won't have much impact locally.
The biggest impact this system will have locally will be the increase in northerly winds that will begin later tonight but really kick in Thursday night into Friday and continue into Saturday. The focus of the winds will be in the mountains and around the Santa Ynez Range in southern Santa Barbara County where wind advisories will likely be needed by Thursday night or early Friday morning. Could even see some localized gusts to around 60 in the usual favored spots like Whitaker Peak. Winds are expected to reach some of the LA/Ventura Valleys and even down into West LA through Santa Monica and LAX, though probably just below advisory levels in those areas.
One last rain chance will develop later Thursday night into early Friday, but mainly just for the northern mountains near the Grapevine where the combination of increasing moisture and strong upslope flow from the north winds may generate some light showers there. Could see a very light dusting of snow on the higher peaks above 6000 feet but no snow expected on the Grapevine.
The windy scenario will continue into Saturday but the flow aloft will be slowly shifting towards the northeast which will result in some areas getting a little less wind but others getting more, especially at lower elevations where winds are highly sensitive to the direction.
Temperatures will remain on the cooler side, mostly in the 60s at lower elevations.
.LONG TERM (SUN-WED)...29/156 PM.
NAEFS forecast pressure gradients continue to strongly favor a lengthy offshore pattern next week with warm and dry conditions and periods of gusty north to northeast winds. Still somewhat uncertain whether it will be a true Santa Ana (northeast) event or whether it will have more of a northerly component. The latest ensembles seem to suggest more of northerly flow, then possibly turning northeast by Tuesday but with very little upper support.
Either way, dry and warmer conditions expected next week with highs warming into the 70s and 80s at lower elevations as a ridge of high pressure develops over southern California.
AVIATION
30/0104Z.
At 2356Z, there was no marine layer at KLAX.
Low to moderate confidence in the coast and valley tafs, except for moderate to high confidence for desert terminals.
As a frontal system moves out of the area, showers have mostly ended. There is uncertainty in how much of a marine layer will form over the coast and valleys. In general, models indicate MVFR conds developing for these areas, but there is a 30 percent chance of lower cigs/vsby forming, and a 30 percent chance that many of these locations remain VFR through the period.
KLAX...Low to moderate confidence in the 00Z TAF. MVFR cigs are forecast between 10Z-16Z, but with low confidence in timing and equal chances of lower cigs, or cigs above MVFR. Any easterly winds will remain less than 7 knots.
KBUR...Low to moderate confidence in the 00Z TAF. There is a 30 percent chance of MVFR cigs during the night to morning period, most likely between 06Z to 15Z.
MARINE
29/207 PM.
Winds and seas will remain below Small Craft Advisory (SCA)
levels through early Thursday morning.
For the waters southwest through northwest of the Channel Islands and along the Central Coast, winds will increase and seas will build between early Thursday morning and Thursday afternoon. The chance for SCA level winds will increase to 90-100 percent by 1 pm PST Thursday. Gale Watch remains in effect due to low confidence in GALE FORCE wind speeds. There is a 40-60 percent chance of GALE FORCE winds between late Thursday afternoon and late Friday night, highest west of a line from Point Sal to San Nicolas Island to 60 NM offshore. There is a moderate- to-high chance of short- period hazardous seas between late Thursday night and Friday.
Winds and seas will diminish some late Friday night into Saturday, but there is a 40-60 percent chance of SCA level winds lingering into Sunday.
Inside the southern California bight, winds and seas will increase to SCA levels between late Thursday morning through Thursday night. There is a 40-70 percent chance of widespread SCA conditions with short-period hazardous seas and gusty west to northwest winds by 8 pm PST Thursday night increasing to 70-100 percent by 8 am PST Friday. An extended period of winds and seas above SCA levels is likely to occur Friday and Friday night, before winds and seas start to diminish late Friday night. Winds and seas should drop below SCA levels between Saturday and Sunday, except for a 40-60 percent chance of SCA level winds across the western portion of the Santa Barbara Channel.
