Area Forecast Discussion...UPDATED National Weather Service Los Angeles/Oxnard CA 1015 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 (WED-SAT)...29/816 PM.
***UPDATE***
Latest satellite and surface observations indicate mostly cloudy skies across interior sections and mostly clear skies elsewhere.
Based on latest radar imagery, shower activity has greatly diminished.
Forecast-wise for the immediate short term, do not think measurable precipitation will be an issue. So, have diminished POPs below 15% for tonight. However, plenty of low level moisture will keep partly to mostly cloudy skies across most areas, especially away from the coast. Overnight, northerly winds should become more pronounced (gust 20-40 MPH) across the I-5 Corridor as well as the Santa Ynez Range.
With the evening update, have decreased POPs for the overnight period. Otherwise, no significant changes have been made.
***From Previous Discussion***
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
30/0614Z.
At 0455Z at KLAX, there was no marine layer nor an inversion.
High confidence in desert TAFs.
Low to moderate confidence in the coast and valley tafs. Cigs will likely fluctuate between 015 and 035 with ocnl SCT conds as well.
Low confidence in VFR transition which may occur anytime between 16Z-19Z.
KLAX...Low confidence in TAF through 19Z then good confidence.
There is a 30 percent chc of no cigs. If cigs do arrive they may arrive as late as 12Z and linger as late as 19Z. Any easterly winds will remain less than 7 knots.
KBUR...Low confidence in TAF through 18Z then good confidence.
There is a 30 percent chc of no cigs. If cigs do arrive they may arrive as late as 14Z. There is a 40 percent chc of BKN025 conds.
MARINE
29/815 PM.
Winds and seas will remain below Small Craft Advisory (SCA)
levels through early Thursday morning, with winds increasing significantly through the day.
For the outer waters and nearshore along the Central Coast, winds will increase and seas will build between early Thursday morning and Thursday afternoon. The chance of SCA level winds will increase to 90-100 percent by 1 pm PST Thursday. Gale Watch remains in effect due to lower confidence in Gales occuring.
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. Short- period hazardous seas are expected 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 in the Santa Barbara Channel will increase to SCA levels between late Thursday morning through Thursday night. There is a 40-60 percent chance of widespread SCA conditions with short-period hazardous seas and gusty west to northwest winds by 8 pm PST Thursday night, then increasing to 70-90 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.
